Lightweight connection method and device based on limited space driving motor and speed reducer

Abstract

Based on a light-weight connection method and structure of a driving motor and a speed reducer in a limited space, according to the characteristics of a high-power-density heavy-load electric wheel, the speed reducer and the driving motor of the electric wheel are axially compressed and integrated together in the limited space position, the axial structure size of the electric wheel is reduced, and the overall weight of the electric wheel is reduced; and the overall miniaturization and light weight of the high-power-density heavy-load electric wheel are realized. According to the light-weight connection method and device based on the limited space driving motor and the speed reducer, on the premise that the high-power-density heavy-load characteristic is kept, the structure is more compact, the axial size is shortened, and the weight is greatly reduced.

Description

technical field [0001] The invention relates to a connection method and device structure of electric drive powertrain components, in particular to a lightweight connection method and device based on a limited space driving motor and a reducer, which is based on a limited space driving motor and a reducer The lightweight connection method and device can effectively reduce the overall structure of driving electric wheels and reduce the weight of the electric wheels; they belong to the technical field of electric drive manufacturing. Background technique [0002] The electric drive using electric power as the driving power is a new energy drive mode widely promoted and applied at present, and its application range is getting wider and wider, and the "two-in-one electric drive assembly" composed of the drive motor and the reducer, and the The "three-in-one electric drive assembly" composed of drive motor, reducer and brake device is also gradually formed. However, as the applic...

Problems solved by technology

[0008] Through the careful analysis of the above-mentioned patents, although these patents all involve the connection of the driving motor of the electric wheel and the reducer, and also propose some improved technical solutions, these technical solutions are still considered from the perspective of separate support of the driving motor and the reducer , so the structural size, especially the axial structural size is still very long, it is not completely suitable as a high power density electric drive wheel structure, especially the lack of consideration of the overall miniaturization and weight reduction of the electric drive wheel, so there is still room for further development research and improve
