比如：当内侧半轴转速降低，外侧半轴必须要加速来实现差速。

For example, when the inside axle shaft slows down, the outside shaft must speed up to allow for the difference.

行星齿轮系统(34)与马达的输出轴(33)相连，以产生转速降低的输出。

An epicyclic gear system (34) is attached to the output shaft (33) of the motor, to produce an output of reduced rotational speed.

转速降低以后，泵的流量会反而增加，而且泵的噪音会降低，但肯定打不到理论流量。

Speed is reduced, the pump flow rate will increase instead, and the noise of the pump will be lower, but certainly can't flow theory.
