As far as the automobile structure be concerned, since the automobile engine output rotation rate is very high, must actual running speed having rotation rate and carriage wheel a set of the speed change device , automobile change gear even if be used to harmonize an engine right away for the optimum performance bringing an engine into play.

就汽车的结构而言，由于汽车发动机的输出转速非常高，为了发挥发动机的最佳性能，就必须有一套变速装置，汽车变速器就是用来协调发动机的转速和车轮的实际行驶速度。

Regarding the speed along with the displacement even change's uniform non-uniform linear motion, its acceleration should define like this: At the unit displacement the speed change (the physics significance is: The speed along with the displacement change "the speed"), like this has:, the acceleration unit should be , Expression speed change which causes in proportion to as a result ,of the speed action of force.if the final velocity is 0, acts according to , namely .

对于速度随位移均匀变化的匀变速直-运动，它的加速度应该这样定义：在-位位移上速度的变化（物理意义是：-速度随位移变化的"快慢"），这样-有：，加速度的单位应该是，表示由于正比于速度的力作用而引起-速度的变化，其中。如果末速度为0，则根据，即。

So it always act as execute component in position control system and wide speed change system. It also fit in situation where need high torque, low speed, or speed change and feed back, or a situation need tensive.

因此，它特别适合于在位置控制系统和宽调速系统中作执行元件，也适用于需要大转矩、低速、转速调节、转速反馈和需要一定张力的场合。
