A single trailing arm hub motor drive module

Abstract

The invention belongs to the field of vehicle engineering, and provides a hub motor drive module with a single trailing arm, which includes a trailing arm mounting bracket, a trailing arm, a hub motor, cables, brakes, heat dissipation water pipes, fastening screws and spring connecting pins; the trailing arm is thin Wall structure, the pin shaft end is coupled with the longitudinal arm mounting bracket to form a rotating pair; the hub motor is installed on the longitudinal arm interface through the fastening screw; the cable and the heat dissipation water pipe pass through the longitudinal arm arm cavity and are exported at the end of the longitudinal arm support; the motor heat dissipation water pipe The water inlet and outlet are placed at the far end of the trailing arm, and the cable outlet is placed at the spring installation side of the trailing arm. The invention uses the hollow thin-walled trailing arm structure to integrate hub motors, brakes, cables, and pipelines, realizing the trailing arm modular integration of the formal drive system; This module has a large jumping stroke of the vehicle, and the trailing arm is suitable for a wide range of swings, and can provide a large suspension lateral stiffness, which is the technical guarantee for the vehicle to pass through ultra-high geometric obstacles. Moreover, the components are modularized, interchangeable, energy-consuming, low in cost, and easy to maintain.

Description

technical field [0001] The invention relates to a driving system for a wheel hub motor of a light ultra-high motor vehicle, which belongs to the field of vehicle engineering. Background technique [0002] The single trailing arm hub motor drive module in the prior art has a complex structure and is not light enough. At the same time, the cables and water pipes are not integrated and orderly enough, which may easily cause problems such as wear and tear of the cables and water pipes. The vehicle driving system puts forward new requirements: super large suspension stroke; vehicle attitude adjustment function; large lateral rigidity; super large driving torque output, etc., which cannot be met by existing technologies. The invention with the application number 201210323493.3 discloses a single trailing arm type independent suspension with an oil-pneumatic spring. The independent suspension is heavy, bulky, and has insufficient carrying capacity. The structural integration of th...

The invention with the application number 201210323493.3 discloses a single trailing arm type independent suspension with an oil-pneumatic spring. The independent suspension is heavy, bulky, and has insufficient carrying capacity. The structural integration of the bracket and the cable pipeline, and the insufficient longitudinal flexibility of the suspension affect the ability of the vehicle to pass through geometric obstacles; integration while the swing arm is heavy
