Not yet from the air suspension “ aluminum 、 steel 、 iron ” Come out of the storm of material dispute , Ideal L9 Recently, something big has happened —— This time, the air suspension failed .

In recent days, , An ideal L9 During the test drive , The front right air spring leaks and is damaged , Unable to drive normally . Once the message flows out , It quickly aroused heated discussion outside , Related topics are also on the hot search . After all , Ideal L9 But it is claimed that “500 Wannei's best home flagship SUV”, As a result, the car hasn't been delivered , The air spring had problems first , This is somewhat beyond the expectations of consumers .

After the event , The ideal aspect is expressed externally , The test drive is due to the use of the buffer ring in the trial production stage , There will be no problem with the actual mass production version , And promised to improve the air spring quality assurance program to 8 Years or 16 Thousands of kilometers .

however , This response to the ideal , Some people think that the ideal is to avoid the important and take the light , It does not state whether there is a problem with the product quality . Ideal L9 What's going on? ？

Ideal L9 can't make a good living 20 Cm deep pit

Discussing ideals L9 Before the incident , Let's first introduce the faulty parts of the vehicle .

Among the statements circulated on the Internet , Ideal L9 It is the air suspension that breaks , But in the ideal external response , Air springs appear again 、 New words such as buffer ring , These professional terms look strange and difficult to understand .

actually ,“ Suspension is a term , We also call it spring .” Automotive analyst 、 Zhang Xiang, Dean of the New Energy Vehicle Technology Research Institute of Jiangxi new energy technology vocational college, told Shentu , Spring is a main part of the traditional automobile suspension system , It mainly plays the role of vibration reduction , The buffer ring is a buffer between the two parts inside the air spring 、 Connecting devices .

Ideal L9 The adaptive air suspension system is made up of air springs 、CDC The variable damping shock absorber and the control arm are jointly composed . among , The function of the air spring is to provide cushioning for the vehicle , But a spring is something that will bounce repeatedly when you press it once , So we also need shock absorbers “ Hold on ” Spring , Don't let it bounce too much .

On the whole , Adaptive air suspension system can be understood as a controllable spring , Whether it's 1 Person or 6 People ride in vehicles , Or passing the deceleration belt , Can make the car body “ suspension ”, Adjust and keep at a proper height .

however , Once there is a problem with the air spring , Bodywork “ Levitation ” It's out of control , For example, like this ideal L9 equally .

In this incident , About the ideal L9 The reason for the problem of the air spring , At present, it is said that “ A deep pit ” Lead to .

Ideal auto official reply said , Chongqing test drive is based on 90 km / Rush through a depth at the speed of hours 20 Cm pit , The buffer ring inside the empty spring is damaged .

As for why the buffer ring is broken , Ideal points the spearhead at the trial parts . It's like interns carrying the pot once something happens , The ideal aspect means , Because of the supply problem , At present, some are ideal L9“ The buffer ring in the trial production stage is used . Although the trial version meets the safety standard , But it will fail occasionally in case of large impact ”.

Besides , Ideal car also emphasizes “ The buffer ring strength of the actual mass production version is that of the trial version 2.5 times ”, There will be no problem in the face of greater impact , And revealed that all test drive vehicles can be replaced with mass-produced parts by next week at the latest .

This simple and crude 、 Reply directly claiming that the vehicle has problems due to the trial parts , Did not calm the external discussion . After all, this air spring failure event , In everyone's eyes, there are too many questionable places .

The biggest doubt is , Why only the air spring fails .

Ideal car official account once published an article about ideal L9 Article on self-developed adaptive air suspension system , It states the ideal L9 The speed is 90 km / Hours 、 And keep it 30 More than seconds , And the speed is lower than 70 km / In an hour , The suspension will be adjusted to a standard attitude , That is, the ground clearance is 176 mm .

The depth of the pit that caused the problem of the air spring this time is 20 centimeter , The outside world generally believes that this ideal L9 When the test drive goes through a deep pit , It is very likely to hit the chassis and the tire will also have problems . But ideal car reply Shenzhen road said , Only the air spring is damaged , There is no problem with other parts .

Former president of Geely Automobile Research Institute 、 Huzhengnan, the current partner of Shunwei capital investment, also questioned this point and said , Ideal L9 The ground clearance of is not so big , If it is true that 90 km / The speed of hours is too 20 Cm deep pit ,“ Under this condition, the tire didn't burst, but the suspension burst , One word for a cow .”

On social platforms , Everyone is also surprised that only the air spring has problems , Many netizens share their experience of driving through pits , Microblogging ID by “ Uncle xiaote ” The blogger said , In order to 60 When passing the pit at the speed of kilometers per hour , His Tesla Model 3 Directly discarded two tires .

Li wants to be beaten in the face ？

At the new car launch , The founder of the ideal car 、 The chairman and CEO Li Xiang revolves around his ideal L9 The suspension introduced a lot , And said “ Even compared with curinan , We are not afraid at all .” In the follow-up marketing , Ideal L9 Also regard suspension as one of the selling points .

This time, the air spring failed due to the trial production , We can't evaluate the ideal L9 Whether there are quality hazards in the suspension , But if according to the ideal present “ Test piece ” Statement , Then ideals need to answer new questions —— Why are trial parts still used now .

From production to market , Need experience CB （Confirmation Build Process validation and manufacturing ） 、VB （Validation Build Engineering validation vehicle ） 、TT （Tooling Trial Production line validation ） 、PP （Pre-Production pre-production ） 、MP （Mass Production batch production ） There are five links .

among , Each phase of vehicle status has corresponding use scenarios . The ideal of this test drive L9 It is the state of quasi mass production vehicles , That is to say, it is in the fourth PP And the fifth MP Between links .

According to the time node revealed before the ideal , Ideal L9 6 month 21 Promulgated by the 、7 Since September, stores across the country have carried out test drive experience 、8 It is officially delivered to consumers in January . Even according to 8 At the end of the month , The formal delivery is less than one and a half months away .

Delivery is imminent , But the ideal test car is still using the parts in the trial production stage , And the strength of mass-produced parts and trial parts is not the same . In this case , Hu Zhengnan raised new questions about the ideal development process and quality management —— Ideal L9 do PPAP （ Production part approval procedure ） Did you? ？

A blogger is driving his dream L9 Later, they also questioned the product . In the video , The blogger's driving ideal L9 The wheel on one side was completely pressed down when turning , The overall chassis is seriously unbalanced . at present , This video has been taken off the Internet , It is not clear whether the problem is also caused by the trial parts .

Besides , For the test drive of the ideal trial model , Zhang Xiang pointed out , This is also a controversial behavior .

“ According to normal requirements , Car companies should not use trial cars for test drives , Because there is no regulation and policy management , Therefore, many car companies use trial cars as test drives , However, the ideal failure is still the first case .” Zhang Xiang told Shentu , The trial production vehicle is mainly used to modulate the process of the production line , You can't sell it , Using it as a test drive can improve utilization .

A function of advertising as a selling point , Overnight, it became the most controversial point of the product , Ideal L9 The changes that have taken place are quite dramatic , However, this transition may have foreshadowed from the beginning .

Before this air spring failure , Ideal L9 The adaptive air suspension system of has also been questioned by consumers because of its material .

Generally speaking , In high-end products , Car companies generally use some aluminum alloy parts to reduce weight , Of course, aluminum alloy is more expensive than steel , The cost of higher . Ideal L9 The rear swing arm of the suspension component is coated with silver similar to aluminum alloy , This is called ideal by consumers L9 Try to fill aluminum with steel .

however , For this question , Li wants to go directly to social platforms “ Open spray ”, He said ：“ I think aluminum must be better than steel and iron , Dismantle the main steel structure of your house , Replace all with aluminum . Where does a car use aluminum , Where to use steel and iron , Not on the head 、 It's decided by typing .”

For the ideal L9 Suspension of , Ideal quickly proposed new solutions , To dispel users' concerns about air springs .

7 month 18 At noon , Ideal car issued a statement saying , Decide to be ideal L9 The air spring （ Including air spring body 、 Air pump 、 Air storage tank ） The quality assurance scheme is upgraded to the same level as the three electricity system 8 Years or 16 Thousands of kilometers , And the second-hand car transaction does not affect the validity of the warranty .

For consumers , Although this commitment seems sincere , However, there are still many doubts about the air spring leakage and damage incident, which have not been explained clearly , This undoubtedly gives ideal L9 The sale of cast a shadow .

As the second mass production vehicle , Ideal L9 High hopes are placed on , From before the press conference “500 Wannei is the best ” Slogan to get BMW at the press conference X7、 Mercedes GLS have undue discussion over sth. , Ideal L9 Have earned enough eyeballs . Ideal tries to rely on L9 To take over the ideal ONE, Create another “ Hot style ”, Realization 9 The monthly delivery volume is more than 10000 . But for now , All this is full of uncertainty .
