A netizen asked us a question about the use of automotive components, saying that why does the steering wheel of a car automatically return to its original position after turning, that is, the return function of the steering wheel. Some car owners may be confused about this, why does the steering wheel automatically return to its original position?

In fact, the steering wheel return is the basic function of a car. Whether the steering is fully or partially turned, the normal vehicle will automatically return to the correct position after releasing it. This is also an important indicator for evaluating the handling performance of a car. Most car steering wheel assistance is divided into hydraulic assistance, electronic assistance, or zero assistance. But this does not affect the automatic return function of the steering wheel.

In fact, the automatic return function of the steering wheel is directly related to the design of the front suspension of the chassis. The parameters of the main pin inclination angle and the main pin caster angle are closely related to the automatic centering ability of the steering wheel. When the vehicle is driving, the steering resistance should be higher than the straight resistance, and the direction will naturally avoid the high resistance and return to the correct direction without external force. These two parameters can ensure the stability of the car when driving in a straight line and the lightness when turning. At the same time, it can ensure that the steering wheel has the ability to automatically return to its original position. And reduce the wear of the steering system. Therefore, the two parameters of the main selling inclination angle and the deregistration inclination angle play a very important role in the steering system of a car.

When these two parameters are incorrect, or when the vehicle cannot return to its correct position after turning, or when the return function is not functioning properly, or when the tires are eating, we need to consider performing four-wheel alignment. Four wheel alignment can adjust the parameters of vehicle steering, including the aforementioned camber angle of the main pin and the deregistration camber angle, to return all parameters to normal for safe driving of the vehicle. Therefore, if the car owner finds that the steering system of the vehicle is abnormal, they can go to the repair shop for four-wheel alignment.
