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

Abstract

The invention relates to an independent steering system with a push-pull cylinder arranged on a single trailing arm of a single trailing arm suspension, and belongs to the field of electric vehicles.The system comprises the single trailing arm, a push-pull cylinder, a steering knuckle, a steering knuckle transition piece and the like. One side of the push-pull cylinder is hinged to the steering knuckle, the other side of the push-pull cylinder is hinged to the steering knuckle transition piece, the steering knuckle is fixedly connected to a wheel assembly, the steering knuckle transition piece is fixedly connected to the single trailing arm, and the steering knuckle and the steering knuckle transition piece are connected through a pair of thrust knuckle bearings and corresponding installation structures to achieve a relative rotation function. The system is compact in structure and stable in steering, provides a beneficial measure for independent steering of the single-trailing-arm suspension, solves various problems caused by a fact that a single trailing arm independent suspension driven by a hub motor only uses differential steering, and has important reference significance forresearch and development of the single-trailing-arm independent suspension.

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 push-pull cylinder is placed on a single trailing arm of a single trailing arm suspension. Background technique [0002] The use of hub motor drive technology can integrate functions such as power, transmission and braking in the rim. Wheeled vehicles with in-wheel motor drive technology can achieve differential steering. The single trailing arm independent suspension has the advantage that the wheel camber and the wheelbase basically do not change when the wheel jumps up and down. At present, wheeled electric vehicles with single trailing arm independent suspension integrated with in-wheel motor drive and differential steering are developing rapidly. Although traditional differential steering does not require a special steering mechanism, differential steering has complex kinematics that ...

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.
