For connecting the output shaft of the gear box to the rear axle, a ling shaft known as propeller shaft is used.

为把齿轮盒子的输出桥连结到后面的轮轴，鳕即是螺旋桨桥的桥被用。

The reason the propeller shaft shortens as the Angle increases is that the rear axle and differential move in a shorter ARC than the propeller shaft.

当角度增加时，传动轴变短的原因是后桥和差速器运动的弧度小于传动轴运动的弧度。

This accommodates any effective change of length of the propeller shaft as the rear axles move toward or away from the CAR frame.

当后桥在车架上向前或向上运动时，这种结构足以调整传动轴长度的任何变化。
