What do you think of the annual inspection report of the car？ What does the so-called braking rate and braking imbalance rate mean？

Original Lao Hou unpacking the car I want to share

The performance is undoubtedly one of the most important active safety features, and its function is to slow down according to the driver’s will until it stops. According to different functions, it can be divided into driving, parking and auxiliary (emergency); according to different structural types, it can be divided into drum and disc types; according to different media, it can be divided into hydraulic and pneumatic types. Generally, hydraulic disc type is used in small, while pneumatic drum type is generally used in medium and large and passenger cars. We can’t simply use good or bad to evaluate them. Although hydraulic disc type has fast response and good heat dissipation, its force is not as large as that of pneumatic drum type, so air pressure is still used more on heavy loads or passenger cars.

The three parameters for evaluating the pros and cons of a car are:, the constancy of, and the directional stability of time. For ordinary people, it is generally used to measure the performance. But for medium and large or passenger cars, the constancy and the directional stability of time are also very important indicators. The most common unqualified items encountered by many cars during annual inspections are unevenness, which actually refers to the imbalance of forces on both sides, and the phenomenon of deviation will occur at time. The whole process is as follows, which can be divided into six stages: driver reaction time, mechanism reaction time, force growth time, device action time, duration, and release time.

The current "Motor Vehicle Safety Technical Inspection Items and Methods" is the national mandatory standard GB21861-2014 that was implemented in 2015. Among them, there are very clear inspection items and inspection standards for the performance of motor vehicles. The inspection items are divided into no-load and parking. For models with more than three axles, the loading is also inspected. The reaction time, constancy, and blocking force are not tested. The inspection instrument is generally a drum-type or skateboard-type force detector. The inspection standards are: single-axis force and not less than 60% of the axle load, the whole vehicle force and not less than 60%, the parking force shall not be less than 20%, the left and right force imbalance of one axis (steering shaft) shall not exceed 20%, and the left and right force imbalance of two axes and three axes (driving and load-bearing axes) shall not exceed 24%. Here are some examples to illustrate the meaning of these parameters.

1. Axle load: also called axle load, which is the load on the axle, which can be understood as the weight borne on the axle. Add the axle load of all axles together. For example, the axle load of one axle is 2829kg, and the axle load of two axles is 6244kg, then the axle load of this car is 2829 + 6244 = 9073kg.

2. Force and force sum: The force here refers to the maximum force generated by each process, and this maximum force is not necessarily generated at the same time. The ratio of the maximum force of the left and right on each axle to the axle load is the axle force sum, and the ratio of all the maximum forces together is the total force sum. They must meet relevant standards. Force sum is also called rate.

For example, in a certain car, the revolver force of one axle is 1017kgf, the right wheel force of one axle is 960kgf, the two-axle revolver force is 1698kgf, and the right wheel force of two axles is 1604kgf. Calculate the force and:

The force sum of one axis: (1017 + 960)/2829 = 69% > 60%, qualified;

The force sum of the two axes: (1698 + 1604)/6244 = 53% < 60%, unqualified;

Total vehicle power: (1017 + 960 + 1698 + 1604)/(2829 + 6244) = 58%, unqualified.

Because the car’s two-axis force and the whole vehicle force are unqualified, the car’s force is determined to be unqualified. It can be seen from the test data that its unqualified force is mainly caused by the small force of the two axles, so we need to focus on repairing the pipeline and device of the two axles. First check whether there are leaks in the pipeline of the two axles. If there are any leaks, we need to deal with them in time. Then check whether the pressure leading to the two axles is normal. If the pressure is obviously too low, it may be a fault or the air pressure of the two-axis air reservoir is insufficient, which should be dealt with separately. If the pipeline fault is dealt with and the force is still too small, the disassembler needs to be disassembled. Generally speaking, it is caused by the wear of the basin and the friction area between the two. It needs to be replaced and the basin is

3. Parking force and parking force sum: Parking force refers to the force generated by pulling up the hand, and parking force sum refers to the sum of the maximum parking force of the left and right wheels. According to relevant standards, the parking force sum shall not be less than 20%.

For example, for a car, the left rear wheel parking force is 1110kgf, the right rear wheel parking force is 949kgf, which is 11514kg, then the parking force of the car is:

(1110 + 949)/11514 = 18% < 20%, unqualified.

The current medium and large and passenger cars generally use the strong pump as a parking, and the parking force is also generated by the two rear wheels. Therefore, the unqualified parking force is generally caused by the unqualified force of the two rear wheels. Generally, the vehicle devices of the two rear wheels need to be overhauled. In addition, the internal fracture of the strong pump, the failure of the hand switch, and the failure of the hand relay valve will also cause the strong pump to fail to fully eject, resulting in too little force. In this case, the relevant pipelines and valves need to be overhauled. Some models use central parking. If the force fails, it is generally caused by the poor contact surface with the basin and needs to be disassembled and repaired.

4. Unbalance rate: The so-called force imbalance rate is also called the left and right force imbalance, which refers to the maximum value of the left and right wheel force difference during the force growth process, and the ratio of the maximum force of the left and right wheels of the shaft measured during the whole process. Generally, it is required that the left and right force imbalance of one axis (steering shaft) shall not exceed 20%, and the left and right force imbalance of two axes and three axes (driving and load-bearing axes) shall not exceed 24%.

For example, the revolver force of one axle of a car is 1312kgf, the right wheel force of one axle is 858kgf, the two axle revolver force is 2360kgf, and the right wheel force of two axles is 2505kgf. Calculations show that the unbalance rate of one axle of the car is 35.6%, which is unqualified; the unbalance rate of two axles is 17.3%, which is qualified.

It is important to note that the maximum force difference does not occur when the maximum force appears at the same time, but occurs during the process of force rise, so its calculation is not simple addition, subtraction, multiplication and division, but is automatically calculated by the detection equipment.

The main reason for the imbalance of the left and right forces is that the difference between the left and right forces is too large or the reaction time is not synchronized. For example, if one side of the device is new and the other side is old, the forces of the two may be very different, and the imbalance rate will be unqualified. There is also a difference in the performance of the left and right pump, resulting in a large difference in the reaction time. In addition, the rust of the shoe shaft can also lead to an imbalance of the left and right forces.

In addition, for multi-axle, it is also necessary to detect its loading rate and unbalance rate. Its detection method is to apply a load to the detected axle to simulate the force under actual driving conditions. It can more accurately detect the force and better fit the actual driving state. Generally, only semi-trailers or four-axle bicycles are detected, and only the second and third bridges are detected. The specific parameters are that the loading rate of the second bridge is greater than 50%, and the unbalance rate is less than 10%; the loading rate of the third bridge is greater than 50%, and the unbalance rate is less than 30%. The reasons for its failure are similar to the above, all due to insufficient force.

Overall, it is very difficult to pass the force test of medium and large or passenger cars at one time. This is mainly because many times, the test line is a quantitative test, and the specific force of each one will be tested, and then whether it is qualified according to the relevant standards is determined. When we drive the vehicle ourselves, it is more of a perceptual cognition. Many times we feel that the performance is good, but as soon as we get on the test line, it fails. Some people do four-wheel maintenance before the inspection, and replace the basin with a new one, but it still fails. This is mainly because the newly replaced basin has burrs on the surface, and the contact surface is not good at first. It takes some time to achieve the best results (more than 75% of the contact surface).

Jiangsu Satellite TV’s 2023 New Year’s Eve concert gathers the spirit of struggle and lights up a happy life

2022 is about to become the past, and a new year is just around the corner! Jiangsu Satellite TV’s spiritual guidance of "lighting up happiness with struggle" once again brings an audio-visual feast to the national and even global audiences at such a moment of saying goodbye to the old and welcoming the new!

The annual New Year’s Eve concert also went to the Cotai Arena in Macau for the sixth time at 19:30 on December 31, and was broadcast live to the world. At this moment in Macau, more than 1,500 people are ready to go, from the directors, stage art, lighting, sound, and visual technology teams behind the scenes to the performers and dance troupes in front of the stage. With their passion for more than a year and the same passion for a happy life, they will present a New Year’s show for all audiences!

From the lineup point of view, every year from January to the beginning of December, Jiangsu Satellite TV’s every big and small news about the New Year’s Eve concert has attracted much attention. This year, the same is true. After several official announcements and the hot search of "small island news" from enthusiastic fans, waves of star and big name franchise news have topped the chart one after another. It shows the appeal and influence of Jiangsu Satellite TV’s New Year’s Eve concert!

From Wang Junkai to Liao Changyong, from Tan Weiwei and Zhang Yifan to Liu Wei, as well as "regular" G.E.M. Deng Ziqi of Jiangsu Satellite TV, the addition of this super-strong lineup has made the 2023 New Year’s Eve concert more popular than ever. After a year, Wang Yuan joined for the first time in his personal capacity, this time he interacted with fans with three very different styles of songs, including "New Boy", "I Can Light a Torch by Myself" and "Living Room Carnival", all of which are new songs.

In addition, Liao Changyong, the original singer of "Tribute to the Warriors", who came with the grand promotion of songs at the 2022 Beijing Olympic Winter Games and Winter Paralympic Awards Ceremony, once again showed the high level of his excellent baritone singers on this familiar stage. And Tan Weiwei’s "explosive" level singing skills and stage appeal; G.E.M. Deng Ziqi’s 2022 almost highlights a whole year’s courage; Zhang Yifan’s extraordinary dance talent; and Liu Wei’s hidden secrets… All in this ordinary and great New Year’s Eve, leaving every viewer with an extraordinary physical and mental experience!

At the same time, the evergreen singer Yang Hongji, the modern brother Liu Yuning, "Principal Tan" Tan Yonglin, the men’s singing group INTO1, "Jiangnan’s first pipa master" Lin Yun, and the powerful female singer Zhang Shaohan in the Chinese music industry will also determine to use their strongest strength and most infectious performances to show their singing voice and stage charm at the Cotai Arena. I still remember that one year ago today, the 80-year-old artist Yang Hongji’s pride did not decrease, and he sang the passionate and striving life of audiences of all ages in the new era with a song of "struggle" 68 times. This time, "The Rest of Life" is more affectionate! Just like the loud slogan of "Lighting up happiness with struggle" always advocated by Jiangsu Satellite TV, it will once again become a loud voice at the end of this year.

As the top show in Asia, Jiangsu Satellite TV’s New Year’s Eve concert is not without the figures of Li Yuchun, Xue Zhiqian, Zhang Jie and Zhou Shen and many other big names. The "god-level" singers, in this new New Year’s Eve ceremony, together with many behind-the-scenes creators of Jiangsu Satellite TV, present a "new" performance and singing mode to the audience. Whether from the perspective of singing or acting, the high-tech presentation method, as well as the new year’s new atmosphere and many other aspects, it is a new "adventure music journey"! Destined, this is another extraordinary night full of endless expectations!

After the release of Xiaomi SU7, many netizens don’t understand why Xiaomi can build a car in three years! Lei Jun： Xiaomi has accumulated 14 years of experience in intellectual creation.

Fast technology news on April 18, this afternoon, Lei Jun started the live broadcast and talked with netizens about Xiaomi car.

Lei Jun said in the live broadcast that after the release of Xiaomi Automobile,Some people on the Internet don’t understand that it took Xiaomi Auto only three years to build a car, which is much faster than the industry average.

In this regard, Lei Jun introduced,Xiaomi has been established for 14 years. Behind the car built by Xiaomi Automobile for 3 years is the 14 years’ experience and technology accumulation of Xiaomi Group.

In addition, some time ago, Tamia Liu, CEO of Zhiji Automobile, also issued a document saying that Xiaomi Automobile started to produce the first complete vehicle from the platform in three years, and began to do research and development from the original platform, and it took 2-3 years to test and verify the complicated complete vehicle and parts.

It doesn’t seem to be enough to optimize it at will. Who knows how to achieve such high efficiency and speed?

Lei Jun also explained that Xiaomi has 14 years of experience and accumulation in starting a business, and has set up a very reliable R&D team.Now there are about three or four thousand engineers, of whom at least one thousand are experts. These experts help Xiaomi avoid many detours.

Moreover, the industrial chain in China has a good foundation, and it is perfect to be an intelligent electric vehicle. Therefore, if we don’t take detours and get the first car out in three years, there is a chance.

Huawei’s automobile leading action! Xiaokang shares announced its name change to ＂Sailis＂

Xiaokang, a local listed company in Chongqing, announced its name change!

Xiaokang Co., Ltd. is the first partner of Huawei’s smart car selection, and its Celestial car and Huawei have built the series of cars. On July 12th, Xiaokang shares opened slightly higher, and then remained volatile. As of press time, Xiaokang shares rose 0.26% to 74.69 yuan. On April 27 this year, the intraday low of Xiaokang shares was 32.70 yuan.

On July 11th, Xiaokang announced that in order to facilitate investors to accurately understand the current company positioning, match the company name with business and strategic planning, unify the company brand image and enhance the brand value, the company intends to change the company name and adjust the company securities abbreviation accordingly. Among them, the abbreviation of the company’s securities is planned to be changed from "Xiaokang Shares" to "Sailis".

"Well-off" represents a glorious past.

"Sailis" represents the future of transformation and development.

"Sailis" is the name of the brand of new energy vehicles under Xiaokang. In 2017, Jin Kang New Energy, a subsidiary of Xiaokang Co., Ltd., acquired AM General’s civil automobile factory in Indiana in the United States. In 2019, Jin Kang New Energy launched the new energy SUV SF5 of the Celeste brand. In May this year, Jin Kang New Energy was renamed Sailisi Automobile Co., Ltd. As a result, Cyrus has basically become synonymous with the new energy automobile sector of Xiaokang shares.

As to why the group name should be changed to "Sailis" this time, Xiaokang shares explained in the announcement that it is to facilitate investors to accurately understand the current company positioning, match the company name with business and strategic planning, unify the company brand image and enhance brand value.　

The word "Xiaokang" has been used as the enterprise name of Xiaokang shares for 15 years. The birth of Xiaokang shares can be traced back to 1986, originally called Chongqing Baxian Phoenix Electric Spring Factory, and later evolved into Yu ‘an Group. In June 2003, Yu ‘an Group and Dongfeng Company jointly established "Dongfeng Yu ‘an Vehicle Co., Ltd." to produce and sell "Dongfeng Xiaokang" brand mini-cars.

In 2007, Dongfeng Xiaokang won the endorsement of Wang Baoqiang, the star of Soldier Assault, which was quickly spread all over the country by regional brands. Together with Wuling Hongguang and Changan Star, Dongfeng Xiaokang was also called "the three giants of China mini-cars". Seeing that the name of "Dongfeng Xiaokang" is so resounding, Yu ‘an Group took the opportunity to directly change its name to Chongqing Xiaokang Automobile Group Co., Ltd. in 2007. Although it was renamed as "Xiaokang Shares" again in 2011, the word "Xiaokang" still exists.

It can be seen that the word "Xiaokang" represents the once glorious past of Xiaokang shares, while the word "Sailis" is regarded by Xiaokang shares as the future of its own transformation and development.

Rename Cyrus

Xiaokang started the third venture.

The renaming of Cyrus is also the inevitable result of Xiaokang’s third venture. In fact, Xiaokang is an enterprise with a history of 36 years. In the fierce market changes, it dares to seize the trend of the times and boldly innovate, and has gone through three ventures. In 1986, well-off people started from a spring and started their first entrepreneurial journey; In 2003, Xiaokang cooperated with Dongfeng Group to enter the field of vehicle manufacturing; Since 2016, Xiaokang has begun to enter the field of new energy, and is committed to transforming the enterprise from a traditional automobile manufacturer into a global smart car brand enterprise with international competitiveness.

Among many enterprises that claim to expand their territory in the field of new energy, Xiaokang is the one with the longest layout and the most practical actions. In the past six years, Xiaokang has invested nearly 10 billion yuan in research and development, and the annual investment in innovative research and development exceeds 10% of sales revenue. It has cultivated and formed core technologies such as electronic control and electric drive with independent intellectual property rights. At present, Xiaokang shares have nearly 3,000 patented technologies, including more than 150 invention patents. The brand-new Phoenix Smart Factory and Liangjiang Smart Factory built in accordance with the Industry 4.0 standard provide a strong guarantee for the company’s new energy vehicle delivery.

Last year, the cooperation between Xiaokang and Huawei pioneered the deep cross-border integration of smart car joint business. The two sides have empowered each other, and the cooperation in core technologies, products and channels has been deepened. The product strength and brand strength of Cyrus have been significantly improved and become a strong dark horse in the new energy vehicle market.

The sales of Wenjie series cars are hot.

Xiaokang Co., Ltd. is the first partner of Huawei’s intelligent car selection model. Sailis Automobile, a subsidiary of Xiaokang Co., Ltd., and Huawei have built AITO brand high-end smart cars, and Huawei also sells cars in stores.

As the first smart car equipped with a HarmonyOS smart cockpit, the sales volume of the M5 has been increasing since it was delivered in March this year.

On July 9, the data released by the Association showed that in June 2022, in the sales ranking of new energy SUV vehicles, the M5 ranked eighth in China with 7021 vehicles, and its sales ranking was one place behind BYD Tang.

In December 2021, the share price of Xiaokang shares fluctuated downward, all the way down to the intraday low of 32.70 yuan/share on April 27, 2022. Affected by factors such as the rising sales of M5, the share price of Xiaokang shares rose sharply in May and June, and rose to 90.5 yuan/share in intraday trading on June 28th, hitting a new high. On July 11th, the share price of Xiaokang shares closed at 74.50 yuan/share, with a total market value of 101.3 billion yuan.

Huawei recently released M7, the second smart car of AITO brand. On July 7th, at the 14th China Automotive Blue Book Forum, Yu Chengdong, managing director of Huawei and CEO of smart car solutions business group, said that the order volume of M7 has exceeded 50,000.

Soochow securities believes that the sales volume of M7 is worth looking forward to. 2022 -2025 is the golden period for the penetration rate of new energy vehicles in China to break through from 15% to over 50%, and it is also the period for business model innovation. The innovative cooperation model between Huawei and Xiaokang is in an important verification period.

AVIC Securities said that there are currently more than 5,500 offline experience stores in Huawei, much higher than other new energy vehicle companies. Huawei’s brand influence and strong channel advantages will empower car companies and help them sell good cars. It is expected that more car companies will choose Huawei’s smart car selection mode cooperation in the future.

Xingyue L car machine update, Baidu Apollo blessing, what upgrades are there in the experience？

Galaxy OS, the vehicle system carried by Xingyue L, is developed by its technology company Yikatong, which integrates the navigation and small voice of Baidu Apollo. It was officially launched in July 2021, equipped with Qualcomm Snapdragon 8155 chip and three screens.

Since its release, Galaxy OS has been upgraded twice. In the latest version 1.2, a lot of simplified upgrades have been made, and AutoLab has the following highlights to share after the experience.

Lightweight application of turning machine

Our mobile phone applications have also developed towards lightweight, and WeChat applets and Alipay applets have been able to replace most APP applications. In addition, in the latest system versions of Huawei and Apple, card-type fast APPlications have been added, so that the functions in the APP can be used conveniently without opening the APP, which saves the process of opening the app.

Xingyue L’s car machine update has also made a light APPlication of the APP, such as Bilibili of the co-pilot entertainment screen. You can see the recommended video content on the homepage of the screen without opening the app.

In addition, temperature control, music switching, and common map functions can be easily completed without opening the application. For example, the temperature can be adjusted by holding down the temperature number by hand and sliding up and down, which is more convenient than the physical knob. In addition, like the shortcut bar of mobile phone, Galaxy OS can open the shortcut button of vehicle control by pulling it from top to bottom, and can also add and subtract functions that can be operated quickly.

Since the Star Yue L central control is a widescreen, the Galaxy OS1.2 version is adapted to the widescreen homepage card, and the owner can directly slide up and down the homepage and choose to display four applications: music, map, WeChat applet and weather. Moreover, compared with the hidden sliding cards of many car companies, the cards of Galaxy OS 1.2 can guide the car owners to use correctly on the UI, which is more convenient and has lower learning cost.

The cockpit experience enters the scene

"Scene" is the most frequently mentioned word in the field of autonomous driving, and now the intelligent cockpit has begun to split the scene. In the Galaxy OS 1.2 version, the thinking of "scene" has also been added.

For example, when the main driver gets on the bus, the central control panel will pop up a shortcut bar for car control for about 5 seconds. In the shortcut bar, it can be used to adjust the seat and open the trunk, which is very convenient. When we experience other smart cars, we need to operate 2 to 3 steps on the screen every time we get on the bus to find the corresponding car control shortcut bar. This function of Galaxy OS is very practical and has a good impression of MAX.

In addition, there are many scenes on the central control screen and the passenger screen, which can be activated by touch screen click or voice control. For example, there is a car wash mode on the central control panel, which automatically closes the window skylight and retracts the rearview mirror after use. The nap mode is common to everyone. You can put down the seat with one button, turn on the ventilation and set an alarm clock.

There are also unusual scenes, such as the Goddess mode. After being enabled, the passenger seat will move backwards, and the seat will move forward after closing the door. The passenger screen will show a pink dynamic effect, and at the same time, a small voice will say: Welcome to the fairy, pick up hot chicks’s skills are full.

For the co-pilot screen, there will be a movie viewing mode. The co-pilot has an independent Bluetooth module, which can connect Bluetooth headsets and enjoy the independent sound source of the co-pilot screen without interfering with the driving of the main driver.

In addition, there is a co-pilot exclusive wallpaper, which can be used by users in need to declare sovereignty.

For the driver, the car WeChat has also been upgraded. When there is no one in the car, the message will be played directly. When there are other people in the car, the message from which friend will be displayed on the central control screen. Only when the owner presses the corresponding button will WeChat broadcast.

Thanks to the powerful computing power of Qualcomm 8155 chip, the co-pilot screen, the central control screen and the instrument screen can also be linked. Through three-finger sliding, the navigation map of the central control screen can be dragged to the instrument screen, and music and movies can be dragged to the co-pilot screen. The co-pilot screen can also query the map and send it to the central control screen for use.

The experience of Galaxy OS made my eyes shine. Personally, I think the user experience is better than that of most new car brands, and it is also better than the Baidu turnkey solution used by some brands before.

Behind this is the advantage of the tripartite joint model of car companies+technology companies+Baidu. Yikatong has assumed the role of product manager, collecting feedback from the daily use of tens of thousands of users, and then integrating Baidu’s technical solutions to polish the functions better.

Press conference of TV series ＂Foreign Aid Doctors＂ showing the feelings of great doctors was held in Beijing.

　　Cctv news(Reporter Zhang Xiaolin Li Yinan) On January 19th, a TV series "Foreign Aid Doctors" was held in Beijing to let more people know about the kindness of foreign aid doctors and feel the essence of China culture and China values.

Launching ceremony site

Launching ceremony site

　　The year 2020 marks the 57th anniversary of China’s dispatch of foreign aid medical teams. China Foreign Aid Medical Team is an international cooperation organization of the Ministry of Health of China. In April 1963, China dispatched the first batch of foreign aid medical teams. The great spirit and touching deeds of China’s foreign aid medical team and foreign aid doctors have enabled China to gain the support of all recipient countries and people in the process of stepping onto the world stage and win international reputation and prestige.

　　Based on the real experiences and events of China’s foreign aid medical team in Africa, The Doctor for Foreign Aid fills the gaps in the related topics in the domestic TV drama field, truly restores the lives of foreign aid medical staff and their selfless and fearless spirit for the broad audience, shows the hard experience unknown to the world in the process of medical aid, and fully reflects the major events that have crossed the medical front in China for more than half a century and the international humanitarian spirit that it reflects to heal the wounded and rescue the dying.

　　Hu Kun, a screenwriter, said in his speech that the actions of the China Foreign Aid Medical Team perfectly explained the sixteen words of "not afraid of hardships, willing to contribute, saving lives and saving lives, and having boundless love". Every time they rescue and help, they plant one friendly seed after another in the hearts of those who have been rescued, in that distant land, and those friendly seeds will grow friendship flowers day by day. He said, "Foreign Aid Doctors" aims to let more people know about the kindness of foreign aid doctors, the essence of China culture and China’s values, and also let other brotherly countries know about the goodwill and beauty released by China to the whole world in the new era.

　　The film was produced by China Population and Culture Promotion Association, and was produced by Beijing Chinese Film and Television Culture Co., Ltd.. Relevant leaders of China Population and Culture Promotion Association, National Health and Wellness Committee, China Foreign Aid Medical Team and other units attended the launching ceremony.
