Independent steering system with dual motors placed on the steering knuckle of single trailing arm suspension

Abstract

The invention relates to an independent steering system with dual motors placed on a steering knuckle of a single trailing arm suspension, belonging to the field of electric vehicles; the system includes a single trailing arm, a steering motor, a steering knuckle, a steering knuckle transition piece, and the like. There are two steering motors symmetrically arranged, which are respectively connected to the steering knuckle through the output shaft of the motor, and at the same time connected to the steering knuckle transition piece through a thrust joint bearing, thereby realizing the relative rotation between the steering knuckle and the steering knuckle transition piece; the symmetrical arrangement of the present invention The two steering motors provide the torque needed for steering evenly, so that the space occupied by a single steering motor is small, and the steering is smooth. It provides an effective measure for the independent steering of the single trailing arm suspension, and alleviates the difference between the use of hub motors in the whole vehicle. The integration of the single trailing arm suspension and the steering system has been realized, which has important reference significance for the research and development of the steering performance of the single trailing arm suspension.

Description

technical field [0001] The invention belongs to the field of electric vehicles with single trailing arm suspension, and relates to an independent steering system, in particular to an independent steering system with dual motors placed on the steering knuckle of single trailing arm suspension. Background technique [0002] Traditionally, wheeled vehicles with single trailing arm suspension driven independently by in-wheel motors need to use differential speed to complete the steering. However, wheeled vehicles with differential steering have low steering efficiency and high power consumption. The mechanical characteristics of the interaction between the tire and the ground are complex and difficult to describe accurately. The tire wear is serious, which limits the steering performance of wheeled vehicles. After adding the independent steering system, various problems caused by differential steering can be alleviated, and the wheeled vehicle with single trailing arm suspension...
