Abstract

The invention provides a pure electric wheelhub drive axle unit. The pure electric wheelhub drive axle unit is of a left-right symmetric structure, more uniform in a loading and bearing capacity, low in processing and manufacturing difficulty, adjustable in a total length of the driving axle, adaptable to various models of vehicles, reduces a development cost, improves a reduction ratio and improves an energy utilization rate. The pure electric wheelhub drive axle unit comprises the main axle body; the main axle body is of a left-right symmetric structure; motor arrangement grooves are arranged on two sides of the main axle body; positioning thread holes are arranged on end surfaces on two sides of the main axle body; the housings of the wheelhub decelerators are fixedly connected to the positioning thread holes on end surfaces of corresponding sides through bolts; a driving motor on the corresponding side is arranged inside the motor arrangement groove; a motor seat of the driving motor on the corresponding side is connected to an inner end surface of the housing of the wheelhub decelerator through a connection flange; and a brake assembly is fixed on the outer end surface of the housing of the wheelhub decelerator.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a pure electric wheel drive axle unit. Background technique [0002] The existing wheel-side electric drive axle directly transmits power to the corresponding wheels through the wheel-side reducer, and its power output consumes a lot of energy. In addition, the left and right parts of the existing wheel-side electric drive The cost is high, the load it bears is uneven, and the corresponding wheel drive axle needs to be independently designed for each model, and its research and development cost is high. Contents of the invention [0003] In view of the above problems, the present invention provides a pure electric wheel drive axle unit, which makes the main body of the drive axle a left-right symmetrical structure, more uniform load bearing, low manufacturing difficulty, and the overall length of the drive axle is adjustable and can adapt to different Models, reduce ...
