Abstract

The application provides a vehicle and a power assembly system thereof, and belongs to the field of power transmission. The power assembly system of the vehicle comprises two driving motors and two speed reducers; each speed reducer comprises a parallel-shaft gear reduction mechanism and a planetary gear reduction mechanism; an input gear of each parallel-shaft gear reduction mechanism is connected to one corresponding driving motor, and an output gear is connected to a driving part of one corresponding planetary gear reduction mechanism; and a driven part of each planetary gear reduction mechanism is connected with a power output shaft. At the same rotating speed, the gear processing difficulty in the parallel-shaft gear reduction mechanisms is relatively difficult, the parallel-shaft gear reduction mechanisms are directly connected with the driving motors, and then the planetary gear reduction mechanisms are connected with the parallel-shaft gear reduction mechanisms to reduce the rotating speed of the planetary gear reduction mechanisms and further reduce the requirements for the gear processing accuracy of the planetary gear reduction mechanisms. Moreover, since each speed reducer comprises two cascaded reduction mechanisms, the reduction effect is better.

Description

technical field [0001] The present application relates to the field of power transmission, in particular to a vehicle and its power assembly system. Background technique [0002] The powertrain is a component used to generate power and transmit power, usually including a drive motor and a reducer. [0003] In related technologies, in order to improve handling performance, the powertrain used by the two wheels arranged on the same axis of the vehicle is generally a distributed powertrain, which includes two drive motors, two planetary gear reducers . Wherein, each planetary gear reducer is respectively connected with a drive motor and a power output shaft, and each power output shaft is connected with a wheel. Each drive motor can control a wheel through a planetary gear reducer. This enables independent control of each wheel. [0004] However, in the distributed powertrain of the related art, the driving motor is connected with the planetary gear reducer, which requires ...
