The drive train users two differentials, with one to produce forward and reverse motion and the other to produce a difference in speed between the two sides.

传动装置有两个差速器，一个用于产生向前和向后的运动，另一个在两侧形成速度差。

This is another one of the maneuvers that reverse direction. The downline can be used to adjust the altitude and speed at the end of the figure.

这是另个一调转方向的动作。下降航迹线可以用于调整动作结束时的高度和速度。

So instead of controlling one arm of the reverse speed, Q1 and Q2 will put a short across the motor to stop it spinning very quickly.

所以，而非控制一只手臂的反向速度，第一季度和第二季度将在短期内全国汽车停止纺纱非常快。
