轴距

轨道和公路车辆中,轴距是指前后车轮轴心的距离。

Wheelbase (measured between rotational centers of wheels)

对于具有两个以上车轴的公路车辆(比如部分卡车),轴距是转向(前)轴与驱动轴组中心点之间的距离;对于三轴卡车,轴距是转向轴与两个后轴之间的中点之间的距离。

公路车辆

[编辑]

汽车轴距是指前轮轴心和后轮轴心之间的水平距离。车辆在平衡时的净转力矩为零,由此轴距和各个车轮承受重量的关系可以用以下公式来表述:

是前轮所受重量, 是后轮所受重量, 是轴距,重心(CG)到后轮的距离, 是重心到前轮的距离, 是车辆的质量重力加速度
