一、操纵轮自振的特征有些车型存在着操纵轮的摆振问题,表现为在汽车直线行驶时,操纵轮(一般是前轮)以一定的振幅和频率绕主销轴左右摆动,并进而导致车身的晃动,一般称为“汽车摆头”。汽车操纵轮的摆振,破坏了汽车直线行驶的稳定性,降低了汽车的使用安全性;使转向系统增加了额外负荷,加速转向系和轮胎的磨损。因此,解决汽车操纵轮的摆振问题,是汽车技术发展中的一个重要课题。汽车操纵轮的摆振,按其振动性质和表现特征,大致可以分为两类,一是具有强迫振动性质的高速摆振,一是具有自激振动性质的低速摆振。
First, the characteristics of the wheel self-vibration Some models exist control wheel vibration problems, the performance of the car in a straight line, the steering wheel (usually the front wheel) with a certain amplitude and frequency swing around the main pin axis, and thus Lead to the body’s shaking, generally known as “car head.” Shimmy car steering wheel, undermining the stability of the car driving a straight line, reducing the safety of the car; the steering system to increase the additional load and accelerate the steering system and tire wear and tear. Therefore, to solve the problem of shimmy of automobile steering wheel is an important issue in the development of automobile technology. Shimmy car vibration wheel, according to its vibration properties and performance characteristics, can be divided into two categories, one is forced vibration nature of high-speed shimmy, one with self-excited vibration of low-speed shimmy.
