A hub motor trailing arm suspension

Abstract

The invention belongs to the field of vehicle engineering and provides a hub motor trailing arm suspension, which includes a trailing arm mounting bracket, a trailing arm, a hub motor, a cable, a brake, a cooling water pipe, a fastening screw and a spring connecting pin; The bracket has a threaded interface, and it is characterized in that a pipeline shield is installed at the opening at the far end of the trailing arm; a metal cover plate is welded at the opening where the spring installation side of the trailing arm is close to the mounting bracket of the trailing arm; the cover plate There is a round hole matching the diameter of the cooling water pipe and the cable; the interface between the trailing arm and the hub motor is a radial flange structure. The structural integration of hub motors, trailing arms, trailing arm brackets, and cable pipelines makes the suspension guide mechanism and motor drive mechanism integrated and becomes a universal interchangeable modular component of the vehicle.

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 br...

Problems solved by technology

[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 brackets, cable pipelines, and insufficient longitudinal flexibility of the suspension affect the ability of the vehicle to pass through geometric obstacles. There is no reasonable design for the heat dissipation of the hub motor, which increases the difficulty of integration
