Abstract

The invention discloses an integrated motor, comprising a motor body and a transmission, wherein the motor body comprises a stator assembly and a rotor assembly, and the motor body is installed in a housing of the transmission; the stator assembly further comprises a stator body and a stator bracket, wherein the stator bracket is mounted on an inner wall of the housing, and the stator body is fixed on the stator bracket. The motor body is integrated into the housing of the transmission, and the motor body and the transmission share the same housing, so that the integrated motor is compact in structure, small in size and light in weight.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an integrated motor of the automobile. Background technique [0002] With the rapid development of new energy vehicles, users have increasingly higher technical requirements for new energy powertrains. Facing the demand for miniaturization, light weight, high efficiency and high performance, the integration of motor and gearbox is a development trend of powertrain. [0003] Some existing motor and gearbox integration schemes are to connect the motor and gearbox through couplings and flanges. Since the connection is only a simple mechanical structure, the size and weight of the integrated assembly are large, which increases the layout of the vehicle. Difficulty increases the energy consumption of the vehicle. Existing motors are generally cooled by water, that is, the motor uses a cooling water jacket structure to realize water circulation and heat exchange. The disadvantage of this ...
