AutoBeta(AutoBeta.net)01/26 Report--

As a hard-line off-road vehicle, WEY Tank 300 has been very popular in the market since its debut, lowering the cross-country threshold for many consumers. However, the recent online exposure of the WEY tank 300 broken shaft, triangular arm fracture event, once again pushed this model to the forefront of the tuyere and waves. In response to the two online incidents, the Great Wall WEY brand issued a note today in response.

The first is the tank 300 nest incident: a netizen uploaded a video on a short video platform, a gray tank 300 tried to cross a small river ditch when it was cross-country on a prairie, and it drove into the small river ditch at a very slow speed, but as soon as the front of the car was launched, I heard a clear and clear sound coming from the right front of the vehicle. In the video, someone shouted: "the triangular arm is broken."

It is worth noting that from the netizen's short video platform, the Tank 300 has experienced several "alternative challenges" before, not only in a "tug-of-war" with excavators, but also with another hardline off-road SUV model, Beijing BJ40.

The Great Wall WEY released the latest explanation for the suspected "nesting" phenomenon of the online tank 300. Great Wall WEY said that regarding the power interruption of the tank 300 during wading, and the suspected "triangular arm fracture" incident, it had established contact with the car owner at the first time of the day, and completed the rescue back to the shop and fault troubleshooting, which was determined to be a fracture of the output shaft in front of the distributor. The on-site disassembly of the transfer box was completed on January 25, and it was found that there were some damage phenomena such as gear overload fracture.

Combined with the analysis of the background data of the tank 300, it is found that the throttle opening of 90% is 99.99% high torque output and the speed is lower than that of the 10km/h during the period of 10-59-14-29 on January 23. During this period, the alternating large fluctuation of transverse acceleration and longitudinal acceleration yaw velocity has the possibility of abnormal operation, combined with a series of tug-of-war challenge videos released by users, the vehicle is continuously overloaded in bad working conditions. as a result, the transmission system is impacted by continuous large torque and heavy load, the overload fatigue of the output shaft leads to dark damage, and the damage expands in the follow-up driving.

The second is the broken axle incident of the tank 300: a netizen uploaded a video on a short video platform showing a gray tank 300 with big feet and off-road tires. When it was about to climb to the top of the "desperate slope", there was a clear sound in front of it, and the brake lights and reversing lights were on, and then the vehicle slipped slowly. In the video, the photographer asks, "is the bridge broken?" Or is the half shaft broken? "

In response to the suspected broken axle of the tank 300, Great Wall WEY said: the car has been modified and raised the suspension system (2 inches higher), replaced the wheel hub and large-size tires (about 1 inch higher), but the transmission half shaft has not been adjusted for suspension and tire parameters changes. After rising, the swing angle and slip of the drive shaft may be out of the design range. In the original factory condition, the maximum design angle of the tank 300 half-axle ball cage universal joint is 22.5 °, but the limit of the modified vehicle has reached 27.5 °. When the vehicle meets the limit working condition, the half-shaft ball cage will be damaged.

It is understood that Tank 300 is the first hardline cross-country SUV launched by the Great Wall WEY brand, which was officially launched in December 2020 with a price range of 17.58-213800 yuan. The power system uses a combination of 2.0T direct injection turbocharged engine and ZF 8AT transmission, with "three locks", tank turning and peristaltic mode to provide technical support for cross-country.

According to the statement released by the Great Wall WEY, the suspected broken shaft and triangular arm of the tank 300 is not a quality problem, but is caused by improper operation by the customer. The automobile industry is concerned that testing the off-road performance of off-road vehicles should go to special off-road sites and make professional cross-country comparisons, rather than testing the ability of off-road vehicles with BJ40 and excavator tug-of-war, this way has no practical reference value, but will be laughed at.
