A four-link hub motor trailing arm suspension

Abstract

The invention relates to a light-duty ultra-high motor vehicle hub motor driving system, and discloses a four-link type wheel hub motor trailing arm suspension, including a trailing arm mounting bracket, a trailing arm, a shock absorber, a steering motor, a hub motor, a brake, The steering knuckle and connecting rod, the trailing arm is a thin-walled structure, and the pin shaft end is coupled with the mounting bracket to form a rotating joint; the hub motor is installed on the steering knuckle through a ball stud; the steering motor is connected to the steering knuckle; the steering knuckle is connected to the trailing arm to form a Rotating pair; one end of the shock absorber is connected to the mounting bracket of the trailing arm to form a rotating pair; one end of the shock absorber is connected to the mounting bracket of the trailing arm to form a rotating pair; The arm, the steering knuckle swing arm and the connecting rod form a four-bar linkage mechanism. The trailing arm suspension of the present invention has a steering function, and the steering and braking performance of the trailing arm suspension can be improved through the four-link parameter design. The suspension component has modular design, interchangeable energy consumption, low cost and easy maintenance.

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 trailing arm suspension 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 system puts forward new requirements: super large suspension stroke; vehicle posture 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 brackets and cable pipelines and the i...

[0002] The trailing arm suspension 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 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 brackets and cable pipelines and the insufficient longitudinal flexibility of the suspension affect the vehicle's ability to pass through geometric obstacles, and at the same time have no significant effect on vehicle steering and braking; the application number is 201520481822.6 Suspension rear trailing arm and suspension rear The utility model of the installation structure of the trailing arm assembly discloses a rear trailing arm of a multi-link suspension, which cannot be well integrated with the hub motor, and the trailing arm structure takes up a lot of space and is heavy
