Abstract

The invention discloses a suspension system and steering system for a distributed driving and independent steering electric automobile. The suspension system and steering system is fixed to an automobile body through an installation support and comprises wheels, a hub motor, a wheel support, a brake, a steering system body and a double-cross-arm suspension system. The steering system body is installed on the installation support of the automobile body, the wheel support is connected with the output end of the steering system, the double-cross-arm suspension system is installed on the wheel support, and the movement of the double-cross-arm suspension system does not interfere with the movement of the steering system body. By means of the suspension system and steering system, the double-cross-arm suspension system with a lateral stabilizer is integrated while each wheel can have large steering angular capability, so that the grounding state of tires is improved, the attachment limit is increased, friction of the tires is reduced, and the side lurch rigidity of the automobile is increased; thus, the control stability is improved, and the whole system is easy to calibrate.

Description

technical field [0001] The invention belongs to the technical field of automobile chassis, and in particular relates to a suspension and a steering system for an electric automobile with distributed drive and independent steering. Background technique [0002] The main structural feature of the distributed drive four-wheel independent steering electric vehicle is that the drive motor and the steering system are distributed to each wheel. The power transmission chain is short, the transmission is efficient, the mechanical connection is small, the structure is compact, and the space utilization rate in the vehicle is high. Distributed drive independent steering electric vehicles can achieve a variety of dynamics control, with good maneuverability and stability. At present, in the realization of the structure of distributed drive independent steering electric vehicles, the commonly used scheme is that each wheel is equipped with a hub / wheel drive motor and a set of electric ste...
