In this state, the front-wheel drive vehicle will cause the left tire to have too small a contact area. After the center of gravity is shifted, the body will greatly compress the tire under the heavy pressure on the left side. At this time, it is very likely that the sidewall of the wheel will be squeezed and damaged, or the wheel hub will directly hit the ground and cause damage. This is why the rear wheel hubs of many front-wheel drive
New Car with torsion beams are easily scratched, or the sidewalls of the rear tires age faster.
In the same state, rear-wheel drive vehicles will cause more serious damage to the wheel hubs and tires, and will also reduce the passing ability (slipping). The rear wheels of front-wheel drive vehicles are driven wheels, and being pulled by the front wheels will not accelerate tire wear or wheel hub bumps at high speeds; but the rear wheels of rear-wheel drive vehicles are power output wheels. At this time, the contact area with the ground is reduced, which will inevitably make it easier to slip, and the high-speed operation of slipping will cause accelerated damage. Many vans or light buses with rear-wheel drive integral bridges are equipped with iron wheels that have obvious line-up. This is the reason.
Note: The structural characteristics of the integral bridge are similar to those of the torsion beam of a New Car, except that it cannot be twisted and deformed, but it also means that the wheels on both sides are fixed on a rigid hard bridge; secondly, rear-wheel drive vehicles will mainly choose an integral bridge with an integrated transmission gear, while the use of a
Fuel Car torsion beam plus rear-wheel drive will have a more complex transmission structure and increase the failure rate of the rear axle. Fortunately, all Fuel Car torsion beam rear-wheel drive vehicles have been discontinued.
