Electric drive rear axle assembly

Abstract

The invention provides an electric drive rear axle assembly, and belongs to the technical field of automobiles. The electric drive rear axle assembly comprises a rear auxiliary frame module, an electric drive module, a rear suspension module, a drive shaft module, a rear brake claw module and a rear suspension module. The rear suspension module comprises an H-shaped control arm, a rear spiral spring, a rear shock absorber, a rear upper control arm, a bridging rod and a toe-in adjusting arm, the H-shaped control arm comprises a first mounting arm, a second mounting arm and a connecting arm, andthe first mounting arm, the second mounting arm and the connecting arm are of an integrated structure; the electric drive module is fixedly installed on the rear auxiliary frame module through the rear suspension module, and the output end of the electric drive module is in transmission connection with the rear brake claw module through the rear drive shaft module. The electric drive rear axle assembly is compact in structure and can be suitable for electric vehicles.

Description

Technical field [0001] The present disclosure belongs to the technical field of automobiles, and particularly relates to an electric drive rear axle assembly. Background technique [0002] The rear axle assembly is an important part of the car. It mainly includes a rear subframe module, a rear brake claw module and a rear suspension module. The rear brake claw module is installed on the rear subframe module through the rear suspension module. [0003] In the related technology of fuel vehicles, the four-link suspension is a common rear suspension module, which mainly includes a longitudinal trailing arm, a lower rear control arm, a rear upper control arm and a front adjustment arm. The longitudinal trailing arm is along the body The lower rear control arm, upper rear control arm and front toe adjustment arm are arranged horizontally along the vehicle body. The longitudinal drag arm, rear lower control arm, rear upper control arm and front toe adjustment arm constitute the suspensi...

Problems solved by technology

[0004] However, the above-mentioned rear axle assembly for fuel vehicles, wherein the four-link suspension has four links (longitudinal trailing arm, rear lower control arm, rear upper control arm and toe adjustment arm), the rear lower control arm Compared with the longitudinal trailing arm, it is relatively long, resulting in too high space occupation, and cannot provide space for accommodating the electric drive unit, so it is not suitable for electric vehicles
