补充资料:飘移
归咎到底就是一种:后轮失去大部分(或者全部)抓地力,同时前轮要能保持抓地力(最多只能失去小部分,最好当然是获得额外的抓地力了),这时只要前轮有一定的横向力,车就甩尾,便会产生飘移。

令后轮失去抓地力的方法:

1.行驶中使后轮与地面间有负速度差(后轮速度相对低)

2.任何情况下使后轮与地面间有正速度差(后轮速度相对高)

3.行驶中减小后轮与地面之间的正压力。

这三项里面只要满足一项就够

实际上1,2都是减小摩擦系数的方法,将它们分开,是因为应用方法不同。

保持前轮抓地力的方法:

1.行驶中不使前轮与地面间有很大的速度差

2.行驶中不使前轮与地面间正压力减少太多,最好就是可以增大正压力。这两项要同时满足才行。
