Trailing arm suspension of hub motor

Abstract

The invention belongs to the field of vehicle engineering, and provides a trailing arm suspension of a hub motor. The trailing arm suspension comprises a trailing arm mounting bracket, a trailing arm,a hub motor, a cable, a brake, a heat dissipation water pipe, a fastening screw rod and a spring connecting pin. The trailing arm mounting bracket is provided with a threaded interface, and is characterized in that a pipeline protective cover is arranged at the opening of the far end of the trailing arm; a metal cover plate is welded at an opening, close to the trailing arm mounting bracket, of the trailing arm spring mounting side; the cover plate is provided with a circular hole matched with the heat dissipation water pipe and the cable in diameter; and the interface of the trailing arm andthe hub motor is of a radiation flange structure. The hub motor, the trailing arm, the trailing arm bracket and a cable pipeline are structurally integrated, so that a suspension guide mechanism anda motor driving mechanism are integrated to form a universal interchangeable modular part 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
