Abstract

The invention provides a power assembly housing and an automobile. The power assembly housing comprises an integrated housing, a speed reducer end cover and a motor end cover, wherein the integrated housing comprises a first mounting space and a second mounting space, the first mounting space and the second mounting space are separated by a connecting structure, and a first positioning hole is formed in the connecting structure; the speed reducer end cover is fixedly connected with a first end of the integrated housing, and a second positioning hole is formed in the speed reducer end cover; and the motor end cover is fixedly connected with a second end of the integrated housing, and a third positioning hole is formed in the motor end cover. By integrating original two housings into the integrated housing, an original spline transition connection structure between a motor and a speed reducer is reduced, and further the problems that the positioning accuracy is low due to spline gaps and the NVH performance of the complete vehicle is low are solved; and a connection structure of a spigot is reduced, so that the positioning accuracy during the assembling of power assemblies is increased.

Description

technical field [0001] The invention relates to the field of power assembly structures, in particular to a power assembly shell and an automobile. Background technique [0002] The lightweight structure has a stronger demand for electric vehicles. The integrated powertrain structure has many advantages of structural optimization and lightweight structure, and has a global development trend. The development of the powertrain structure, the design and development of the integrated shell structure and the realization of the process are of great significance in the entire integrated development. [0003] In the prior art, after the motor and the reducer are installed in their corresponding housings, they are installed and matched as a whole. The two housings mean that there are two partition connection structures, which is not conducive to lightweight design. At the same time, during assembly When the positioning effect is poor, the NVH performance of the assembled vehicle is p...
