Abstract

A three-in-one electric drive assembly structure comprises an integrated main shell, a drive motor module, a speed reducer module, a controller module and an integrated cooling water channel, the drive motor module, the speed reducer module, the controller module and the integrated cooling water channel are arranged in the integrated main shell, the drive motor module is connected with the speed reducer module through a spline, and the controller module is connected with the drive motor module through a three-phase copper bar. A motor, a controller and the speed reducer module are integrated,and the motor and the controller are connected through a three-phase copper bar; the motor and the speed reducer module adopt the integrated shell, and a motor output shaft and a speed reducer moduleinput shaft are connected through the spline to transmit torque; and the motor and the controller adopt an integrated cooling water channel, the outlet of the controller cooling water channel and theinlet of the motor cooling water channel are coaxially designed and connected through a connecting water pipe, and integrated cooling is achieved.

Description

technical field [0001] The present invention relates to a technology applicable to new energy vehicles, in particular to a three-in-one electric drive assembly structure applicable to the front compartment or rear compartment of pure electric and fuel cell vehicles. Background technique [0002] Most of the existing electric drive assemblies are integrated with the motor and gearbox, and then the controller is assembled. The motor and the controller are connected through an external high-voltage wire harness; the cooling water channel of the motor and the cooling water channel of the controller are connected in series through an external pipeline; this scheme There are disadvantages such as large volume, heavy weight, many connecting parts, and high cost, which are not conducive to the layout of the whole vehicle. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention proposes a three-in-one electric drive asse...
