Abstract

The invention belongs to the technical field of electric drive axle assemblies, and particularly provides an electric drive axle assembly for an automobile and the automobile. The invention aims at solving at least one of the problems that an existing electric drive axle assembly for an automobile is small in output torque, and along with increase of the torque, the development difficulty is greatly increased, the service life of a gear and a bearing is shortened, the strength of a shell is reduced, the size of the electric drive axle assembly is too large, and frame suspension design is difficult. In order to achieve the purpose, the electric drive axle assembly comprises a first motor and a second motor, the first motor and the second motor are arranged in the middle of the electric drive axle assembly side by side along the X axis, and output shafts of the first motor and the second motor are parallel to the Y axis. Therefore, the Y-direction layout is optimized, the problem that an existing electric drive axle assembly is too large in size is solved, and then the electric drive axle assembly can be conveniently carried on an automobile frame chassis.

Description

technical field [0001] The invention belongs to the technical field of electric drive axle assembly, and specifically provides an electric drive axle assembly for automobiles and the automobile. Background technique [0002] With the continuous development of automobile technology, the torque requirements for the electric drive axle assembly of automobiles are also increasing. [0003] The existing electric drive axle assembly for automobiles usually adopts the assembly structure of a single motor and a reducer, and usually develops a larger motor, a larger reducer, and a larger inverter to improve the electric drive. The torque of the transaxle assembly. [0004] However, the existing electric drive axle assembly for automobiles has a small output torque, and with the increase of torque, the difficulty of development is greatly increased, the service life of gears and bearings is reduced, the strength of the housing is reduced, and the size of the electric drive axle assem...
