Abstract

The invention relates to an independent steering system with a steering motor arranged on a single trailing arm of a single trailing arm suspension, and belongs to the field of independent driving electric vehicles. The system comprises the single trailing arm, the steering motor, a steering knuckle and the like. The steering motor is fixedly connected to the single trailing arm through a motor support, and an output torque of the steering motor is transmitted to the steering knuckle driving a wheel assembly to steer through a motor output shaft, a steering rocker arm, a steering pull rod anda steering knuckle arm. The steering knuckle and a steering knuckle transition flange are connected through a pair of angular contact knuckle bearings and corresponding installation structures to achieve a relative rotation function. The system is compact in structure, flexible in steering and high in integration degree, various problems caused by a fact that the single-trailing-arm independent suspension only depends on differential steering of a hub motor are solved, and the system has important significance in research and development of independently-driven single-trailing-arm suspensions.

Description

technical field [0001] The invention belongs to the field of electric vehicles with single trailing arm independent suspension, in particular to an independent steering system in which a steering motor is placed on a single trailing arm of a single trailing arm suspension. Background technique [0002] The single trailing arm independent suspension using hub motors to directly drive the wheels has a very broad development prospect in the field of electric vehicles. This structure has the advantages of simple structure, saving space in the vehicle, and maintaining the stability of the driving direction. The single trailing arm independent suspension driven by the hub motor generally adopts differential steering. Due to the complexity of its movement, it is difficult to accurately describe the steering characteristics, and the tires are prone to side slip and wear. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the...
