1·The trailing wheel has to the electrical machinery feedback electricity generation performance.

后轮具备对电机反馈发电性能。

2·It is one of trailing arm suspension that can only be applied in the rear axle and cannot be applied in the front steering axle, so there are only two wheel alignment parameters: toe-in and camber.

它属于纵臂式悬架，只能用于后轮，且不能用于转向轮，因此其定位参数只有车轮前束和外倾角两种。

3·Machining precisions of axles and holes correlating with the space position of brake drum's positioning dowel on the trailing arm are the main factors determining the rear wheel alignment parameters.

决定后轮定位参数的主要是与纵摆臂中制动鼓定位销轴空间有关的轴和孔的加工精度。
