Embodiment Construction

[0032] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0033] In the present disclosure, the orientation words "inside" and "outside" are usually used for the outline of the component itself. In addition, the terms "first" and "second" used in the present disclosure do not indicate any order or importance, but are used to distinguish one element from another element. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated.

[0034] Such as figure 1 with figure 2 As shown, the present disclosure provides a steering return assist device, which includes an external gear 2, an internal gear 3, a ho...

Abstract

The present disclosure relates to a steering return assist device, a steering mechanism and a vehicle, wherein the steering return assist device includes an external gear (2) fixedly sleeved outside the steering column (1), a The outer internal gear (3), the casing (4) sheathed outside the internal gear, and the elastic element (5), one end of the elastic element is connected with the casing, and the other end is connected with the internal gear. One of the external gear and the internal gear has fixed teeth, and the other has rotatable teeth, so that when the steering column rotates in the first direction, the external gear meshes with the internal gear for transmission, and when the steering column rotates in the second direction, the external gear meshes with the internal gear for transmission. The gear and the internal gear slide relatively. Through the above technical solution, a mechanically structured steering return assisting device is provided, so that even when the vehicle has a small steering force such as low speed and small angle turning, it can produce a better return effect.

Description

technical field [0001] The present disclosure relates to vehicle manufacturing technology, in particular, to a steering return assist device, a steering mechanism and a vehicle. Background technique [0002] The steering return auxiliary device is mainly used for the process of automatically returning from the curve to the straight line after the steering action of the car. The quality of the vehicle's steering return performance directly affects the evaluation of the vehicle performance. At present, there are two types of power steering systems in the market, hydraulic power assist and electric power assist, and they are limited by the structure of automobile tires, and the steering resistance is relatively large. The back-to-center resistance of the car also increases, especially in the process of low-speed turning or small-angle turning of the car, there are phenomena such as insufficient steering torque back to right. The steering torque is small, and the torque generat...
