Description

technical field

[0001] The invention belongs to the technical field of integration of transmission and maintenance of electromechanical automatic transmissions for pure electric vehicles, and in particular relates to an integrated assembly of transmission and maintenance of electromechanical automatic transmissions for pure electric vehicles. Background technique

[0002] At present, pure electric vehicles at home and abroad are still in their infancy, and are basically produced according to the traditional in-wheel motor direct drive method. Because traditional cars use fuel engines, pure electric vehicles are powered by motors and control systems, and their spatial layout is different. The engine of a traditional car almost occupies the front working compartment, as well as the fuel tank exhaust pipe assembly and so on. The pure electric vehicle is different, it increases the installation position of the battery pack. However, in the traditional pure electric hub motor d...
