Independent steering system with push-pull cylinder placed on the single trailing arm of the single trailing arm suspension

Abstract

The invention relates to an independent steering system in which a push-pull cylinder is placed on a single trailing arm of a single trailing arm suspension, belonging to the field of electric vehicles; the system includes a single trailing arm, a push-pull cylinder, a steering knuckle and a steering knuckle transition piece; One side is hinged on the steering knuckle, the other side is hinged on the steering knuckle transition piece, the steering knuckle is fixed on the wheel assembly, the steering knuckle transition piece is fixed on the single trailing arm, and the steering knuckle and the steering knuckle transition piece pass through A pair of thrust joint bearings and their corresponding installation structures are connected to realize the relative rotation function; the invention has a compact structure and stable steering, and provides a beneficial measure for independent steering of a single trailing arm suspension, which solves the problem of independent steering of a single trailing arm driven by a hub motor. The various problems caused by the suspension only using differential steering have important reference significance for the research and development of single trailing arm independent suspension.

Description

technical field [0001] The invention belongs to the field of single trailing arm independent suspension electric vehicles, in particular to an independent steering system in which a push-pull cylinder is placed on a single trailing arm of a single trailing arm suspension. Background technique [0002] The use of in-wheel motor drive technology allows functions such as power, transmission and braking to be integrated into the rim. Differential steering is possible with wheeled vehicles with in-wheel motor drive technology. The single trailing arm independent suspension has the advantage that the wheel camber and the wheel base do not change basically when the wheel jumps up and down. At present, the single trailing arm independent suspension wheeled electric vehicle that integrates in-wheel motor drive and realizes differential steering is developing rapidly. Although the traditional differential steering does not require a special steering mechanism, the differential steer...

AI Technical Summary

Problems solved by technology

Although the traditional differential steering does not require a special steering mechanism, the differential steering has complex kinematics that is not easy to describe accurately, and at the same time, it causes severe friction to the tires, which limits the kinematic performance of related vehicles.
