Single trailing arm hub motor driving module

Abstract

The invention belongs to the field of vehicle engineering, and provides a single trailing arm hub motor driving module, which comprises a trailing arm mounting bracket, a trailing arm, a hub motor, acable, a brake, a heat dissipation water pipe, a fastening screw rod and a spring connecting pin. The trailing arm is of a thin-wall structure, and a pin shaft end of the trailing arm is coupled withthe trailing arm mounting bracket to form a revolute pair. The hub motor is installed on a trailing arm connector through a fastening screw. The cable and the heat dissipation water pipe penetrate through a trailing arm cavity and are led out from a trailing arm support end. A water inlet and a water outlet of a motor heat dissipation water pipe are formed in the far end of the trailing arm, and acable leading-out opening is formed in the installation side of a trailing arm spring. The hub motor, the brake, the cable and the pipeline are integrated through a hollow thin-wall longitudinal armstructure, and longitudinal arm type modular integration of a form driving system is achieved; according to the module, the jumping stroke of the vehicle is large, the longitudinal arm is suitable forlarge-range swinging, large suspension lateral rigidity can be provided, and the technical guarantee is provided for the vehicle to pass through ultrahigh geometric obstacles. Components are designedin a modular mode, interchangeability is achieved, manufacturing cost is low, and maintenance is easy.

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...

[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 stiffness; 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 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
