Abstract

The invention relates to an electric automobile distributed type drive axle assembly. The electric automobile distributed type drive axle assembly comprises a reducer, a left wheel in transmission with a left half axle and a right wheel in transmission with a right half axle. The electric automobile distributed type drive axle assembly further comprises a motor M1 and a motor M2 which are integrally fixed with a reducer shell on the same side and are longitudinally arranged along a vehicle, and a left transmission assembly used for realizing the transmission of the left half axle and the motorM2 and a right transmission assembly used for realizing the transmission of the right half axle and the motor M1 are arranged in a reducer shell. Compared with the prior art, the electric automobiledistributed type drive axle assembly has the advantages of distributed type drive, more steady operation, saving longitudinal arrangement space, better energy consumption and dynamic control performance and the like.

Description

technical field [0001] The invention relates to the field of drive transmission of electric vehicles, in particular to a distributed drive axle assembly of electric vehicles. Background technique [0002] Under the background of vigorously advocating environmental protection, electric vehicles have become a hotspot in the research of the automobile industry due to their low energy consumption and low emissions. The distributed drive system has become an important research direction of new energy vehicles due to its advantages of simple structure and high transmission efficiency. According to the location of the motor, pure electric vehicles can be divided into two categories: centralized motor drive and distributed drive. Distributed drive is divided into two types: wheel hub direct drive and high-speed motor accelerator drive. Distributed drive usually uses motors installed on the drive wheels to transmit power to the wheels directly or via a reduction gear to drive the c...
