Tank 300, as a hard cross-country SUV built by the Great Wall WEY with a new platform, has attracted the attention of the market since its debut. After listing, it also gets many choices from potential consumers. Recently, a Guangzhou car owner drove a tank 300 and broke its shaft while climbing a hill. According to the video picture, we can see that the right front wheel of the vehicle is tilted up during the driving process, and the drive half-shaft ball cage of the main driving position is broken.

For this matter, netizens have also commented: more than 200,000 cars have to play a hundred thousand tricks, but also ask so much. He is a city car, why do they want to run off-road? they really drive 200000 of the cars as tanks.

According to relevant data, Tank 300 has had many cases of broken axes and burrowing, and the Great Wall has also issued relevant instructions on the incidents of broken shafts and nests.

The first is a tank 300 nest incident: a netizen posted a video on a short video platform in which a gray tank 300 tried to drive through a small ditch and drive into the ditch at a very slow speed when it was cross-country on a plain, 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 Beijing BJ40.

In response to the suspected "nesting" phenomenon of the online tank 300, the Great Wall WEY released a description of the recent tank 300 incident. 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 explanation 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.

According to the statement released by the Great Wall WEY, the suspected broken axle and nesting incident of the tank 300 is not a quality problem, but caused by improper operation of the customer. 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. Figures show that 5500 tanks were sold in April, with a cumulative sales of 19823 from January to April.

Great Wall said in April that orders for tank 300s had now exceeded 14000, with deliveries of 12000-13000 if it were not affected by chip shortages. According to the plan, the domestic sales target of tanks is 100000 this year, 350000 in the global market in 2023 and 500000 in 2025.

For the netizens' broken axis incident exactly what caused it, we can only wait for the official announcement. Although Tank 300 is positioned as a cross-country SUV, reasonable cross-country is even more important for cross-country enthusiasts.
