一个可能有帮助的tip：在一个坡度稍微大点的地方练或许更容易。这听起来比较

显。带来的缺点是转弯半径会增大，后胎slip angle减小，understeering多一些。
toe out 相反，可以加快入弯角度，减小转弯半径，增加后胎slip angle，增加
overstering. (我这里说的都是RWD或者AWD啊）
一个车的后轮是调教成toe in还是toe out主要是看这个车干什么用和这个车的其他参

会带来过多的understeering，但出弯的稳定性大大增加，踩油门的时机也可以提前，
踩油门深度加大。总体上是受益的。
3系这种讲究操控的菜车，toe in就没必要了。因为过弯速度不会太快，入弯也不见得

发帖数: 606 | 45 有个事一直想不明白，来请教一下。假如车是前置后驱，想减少understeer，所以就要
增加后轮的slip angle，举几个例子
1-重心后移，这个很好理解，增加后面的压力来增加slip angle
2-后悬挂调硬，过弯的时候如果悬挂越软，外侧的轮子的受力就越大，如果将悬挂调硬
，两侧的受力分布会更平均所以外侧轮的受力会减小，因此后轮slip angle就会减小，
那么为什么还会导致oversteer呢？？？
3-降低后轮胎压和用窄胎也可以减少understeer，但减少胎压增大接触面积不是跟用窄
胎相违背么？？而且autox的时候我问过好几个老油条，他们都说是增加后轮胎压来减
少understeer，谁能帮忙解释下这个？？难道induce和cause oversteer不是一个意思
？ |
|
u******w
发帖数: 1882 | 46 这个是是对轮胎特性的误解。understeering和over在本质上的定义是比较前后轮的
slip angle，而slip angle是只要有侧向里就会发生的，不一定用等到侧滑，因为轮胎
不是刚体。也就是说比如车在前进时哪怕你用人力在侧面推一下车，前后轮都会产生侧
偏角（slip angle），只不过很小。而转弯时就相当于有个侧向力作用，这个时候前后
轮的侧偏角差别决定了整车是过度还是不足转向。
当重心后移时，转弯时相当于后轮受到的侧向力变大，所以后轮的侧偏角变大，整车更
趋于过多转向。
