动平衡是什么?汽车的车轮是由轮胎、轮毂组成的整体。由于制造上的原因,使这个整体各部分的质量分布不可能非常均匀。当汽车车轮高速旋转起来后,就会形成动不平衡状态,造成车辆在行驶中车轮抖动、方向盘震动的现象。为了避免这种现象的发生或是消除已出现的这种现象,就要使车轮在动态情况下通过增加配重的方法,使车轮校正各边缘部分的平衡,这个校正的过程就是人们常说的动平衡。 What is the dynamic balance? The car’s wheels are made up of tires and wheels. Due to manufacturing reasons, the mass distribution of the whole part can not be very uniform. When the car wheels rotate at high speed, it will form a dynamic unbalanced state, resulting in the phenomenon of wheel shaking and steering wheel vibration when the vehicle is moving. In order to avoid the occurrence of this phenomenon or to eliminate the phenomenon that has appeared, it is necessary to make the wheel correct the balance of each edge part of the wheel by increasing the counterweight under dynamic conditions. This correction process is often said Balancing
