汽车的悬架是汽车车架(或承载式车身)与车桥(或车轮)的传力连接装置,它使车轮在行驶中所承受的冲击不直接传到车架(或承载式车身)上,以吸收和减小振动,提高汽车行驶的稳定性和平顺性。悬架的主要部件是弹性元件和减振器。汽车在行驶中,当弹性元件发生变形时,减振器能迅速减弱其振动,缩短振动时间,从而改善车轮与道路的接触状况,改善转向轮的操纵稳定性。下面列举两例在汽车行驶中易于发生的与悬架有关的故障。 Suspension of a car is a force transmission connecting device between a vehicle frame (or a load-bearing body) and an axle (or a wheel), so that the impact on the wheel during traveling is not directly transmitted to the frame (or the load-bearing body) , To absorb and reduce vibration, improve vehicle stability and ride comfort. The main components of the suspension are elastic elements and shock absorbers. When the vehicle is moving, when the elastic element is deformed, the shock absorber can rapidly weaken its vibration and shorten the vibration time, so as to improve the contact condition between the wheel and the road and improve steering stability of the steering wheel. Below are two examples of suspension-related problems that are prone to occur while driving a car.
