AI Technical Summary

Technical Problem

Existing electric drive assemblies in new energy vehicles have low space utilization due to their split structure, and their cooling systems exhibit long water channel layouts with high flow resistance, leading to low cooling efficiency.

Method used

Integrate the drive motor and speed reducer into a motor assembly, integrate the motor controller, resolver, and on-board charger into the electronic control assembly, and share a unified cooling system between them, with a closed forced circulation water cooling system that includes a first and second cooling unit to shorten the cooling water channel path and reduce flow resistance.

Benefits of technology

Improves space utilization, reduces weight, and enhances cooling efficiency by shortening the cooling water channel path and reducing flow resistance in the electric drive assembly.

Abstract

An electric drive assembly (10), relating to the field of new energy vehicles. The electric drive assembly (10) comprises a motor assembly (100), an electric control assembly (200), and a cooling component (300). The electric control assembly (200) is arranged beside the motor assembly (100), the cooling component (300) being arranged between the electric control assembly (200) and the motor assembly (100). The motor assembly (100) comprises a housing (110), a speed reducer (120), and a driving motor (130). The housing (110) is arranged around the outer side of the driving motor (130) and has a first housing part (113) and a second housing part (114), an accommodating cavity (115) being formed between the first housing part (113) and the second housing part (114). The speed reducer (120) is arranged on the outer side of the housing (110). The cooling component (300) comprises a first cooling unit (310) and a second cooling unit (320), the first cooling unit (310) being arranged between the electric control assembly (200) and the motor assembly (100), and the second cooling unit (320) being arranged inside the accommodating cavity (115). The first cooling unit (310) and the second cooling unit (320) are both provided with cooling channels that are in communication with each other, a cooling medium flowing in the cooling channels so as to cool the electric drive assembly (10). Further provided is a vehicle. In the electric drive assembly and the vehicle, routes of cooling water channels are shortened, thereby improving cooling efficiency.
