2020 September 7, ideal ONE extended-range hybrid vehicles take place on 4 “off axis” accident, then the ideal official statement, “After the accident site survey and driving record instrument playback, the user is not noticed when it rains the road ahead to 51 km / hour speed fitted to the middle of the road cement flower beds. ideal automotive aftermarket team has with the user at the scene confirmed the cause of the accident, and the owners have also been reported Insurance for repair, and made clarifications in the user group where, thanks for your concern. ”
, paragraph 2 of the vehicle over the manufacturing, the ideal extended-ONE hybrid knuckle arm ball pin departing car front suspension occurs, i.e. the media as many accidents “off-axis.” 2020 September 8, ideal ONE on fire accident occurred three, four “off-axis” accident.
with a few cases of “off-axis” accident declared before the occurrence of a phase identical, over the official first four statements “off axis” emphasizes speed because unilateral at 51 km / h collisions, resulting in lower arm front suspension ideal ONE (ball pin) out of the lower section of the front steering.
After a first occurs over ONE “off axis” accident, the media questioned arm strength, “plastic” as used results in insufficient. Then over the official statement, the ideal swing ONE inner member is stamped steel, steel material of the upper layer, the lower layer is a “PA6 + GF5O” Nylon / fiberglass composites, polyurethane and a nylon PA6 in , 50 and added to the percentage of glass fiber reinforced plastic and thus from the surface of the same.
Pictured on August 19, the first three “off-axis” ideal ONE actual scene of the accident occurred close-up status.
In fact over ONE “4 break even” accident, the front suspension arm composite material is not broken, and the sub-frame of the fixed arm ball intact the two groups, but can be found due to the image size is small, and can not confirm the final knuckle under fixed arm ball pin is intact.

confirmed that the accident of three “off-axis”, the over ONE front hem the arm is not broken, and fixed to the front sub-frame, the arm from the ball pin and the knuckle. Can not be confirmed is whether the fracture arm ball pin from the front of the knuckle. In fact, as long as the search keyword “arm broken down”, you can find a plethora of the true meaning of “off-axis” picture accident cases.

Sign close-up state. The use of the same over the ONE model McPherson front suspension structure, and the arm lower front broken into three parts.

should be particularly noted that the true meaning of “off-axis” accident, or shaft fracture, break or lower arm. In the past few years, Nissan sold in China, Toyota, Ford, Buick and other models Tesla have suffered under a different number of front or rear swing arm is ruptured. Rupture of these swing arms, the aluminum material and steel material relates to the swing arm fracture position is also fixed to the arm structure from the ball pin and the subframe. Among them, the most influential, because of “off-axis” and recall the accident was undoubtedly the Beijing Benz E series.
The key mechanism in combination with the swinging arm knuckle
of – a ball pin, is crucial for the operation of a steering member of the vehicle, and includes a longitudinal oscillation of the front suspension function. Accordingly, or bolted, or integrated hem ball pin, it is often “fine” is made, and a sufficient strength to bear. Even in a vehicle on the road bumps occur, to withstand the impact of a range of a collision, under the arm, and a knuckle-ball, must ensure intact.
In the event of a collision, the lower arm, the ball pin and the knuckle withstand impact forces overBy setting the range, or even broken off (suspension) is inevitable. However, similar to some of the brand’s models in a short period of intensive spate of accidents “off-axis”, will lead to aggregation of rights owners and trigger a brand crisis.
over the graph on the lower front arm ONE manufacturing a composite material (yellow arrow), the ball pin (red arrows) and a steering front section close-up detail. It is seen from FIG Sign group, a lower front arm over ONE configuration integrated with the ball pin, and the lower end section of the front steering by gravity “top.”
The picture shows the
May 11, 2 cases of “off-axis” ONE occur over the actual state of close-up scene. ONE and over this shoulder in the collision with the right front wheel, and the knuckle arm departing from a right front suspension.
The picture shows the close-up details on May 11, over the first two ONE occurs “off-axis” accident scenes enlarged image.
Red Arrow: the use of composite materials is not broken arm
yellow arrow: pin fixed to the lower arm ball deletions
blue arrow: front knuckle suspected intact [ 123]
the figure below shows an ideal ONE on the arm, the fitting state of loading is not close-up detail. Visible red arrow ball pin is fixed to the lower front end of the swing arm. Due to lack of material for the study of the more the determination can not be determined over the ONE “4 break even” is deleted because the ball pin is disengaged from the steering knuckle arm, the ball pin without deletion of from about knuckle arm.
I have something to say:
before ES8 Wei to burst into flames when the accident occurred, Wei also the first time to the official statement issued three related, or because the vehicle battery is damaged, or shake the pan to the battery supplier Ningde era design flaw. However, in the event of the four combustion accident, Wei to ES8 we had to be recalled.
after
within 1 month Wei to ES8 “4 even burn”, 4803 Recalled suddenly set to provide a battery module carrier Ningde age, own productionBattery assembly. Wei, vice president of Power Engineering Huang Chendong call issued “a number of issues regarding the battery recall instructions” on Wei to App.
August 29, the new forces repairer ideal leader Lee would like to open a squalling user activity in Chengdu, say three consecutive in a time division multiple ” TMD “. From one perspective, Lee would like the three “TMD” also responded to the question ONE choice for the ideal extended-range electric technology roadmap: Why
Today, I would like to share a topic “can not be extended-range electric? “, which is a very important topic. Let me say that I am a harsh word, ruined a bunch of technology, every day we rushed bb, what is behind the extended-range electric technology, may I ask, do they TMD fart out of the technology? Correct. Let a group of users without thinking and did not care about the user group of people, every day of the Research Technology, TM what technical route ah? Nonsense!
However, the route of the problem drive technology soon attracted media crowd, ideal ONE took place on 4 “off axis” accident. Put aside “4 break even” ideal ONE link in the collision, more than two tons of vehicle weight, McPherson front suspension, designed to balance the needs between the front drive axle load, and whether full and complete prior to listing reliability verification. It seems to be a neglected problem: ideal ONE implemented in August 2020 delivered 2711 units, compared with July delivery rose slightly MoM 10.9 percent (July: 2445), a total of 14,656 deliveries. 1.5 million units in less than ideal ONE sold in total, took place the probability of four incidents of “off-axis”, enough to make cars with the same new forces Wei to ES8 “4 even burn” comparable to. After
will be described on the ideal extended-ONE employed Prospect hybrid multi-dimensional parsing technique, to be continued. . . .
