Centering mechanism used for vehicle steering

Abstract

The invention discloses a steering centering mechanism, which is suitable for a rhombus-like bus. The mechanism comprises a fixing base, wherein a fixing shaft arranged on the fixing base is provided with a rotary drum which can rotate around the shaft; the two ends of the rotary drum are respectively provided with a front side arm and a back side arm; a front ball bearing is hinged with the front end of the first side arm; one end of a front connecting rod is connected with the front ball bearing; a back ball bearing is hinged with the front end of the back side arm; one end of the back connecting rod is connected with the back ball bearing; the lower end of a front centering rotary drum positioned between the front side arm and a front bracket is arranged on the fixing shaft and is rotated around the fixing shaft along with the rotary drum; the front end of the front centering rotary drum is hinged with one end of a front spring; the lower end of a back centering rotary drum positioned between the back side arm and a back bracket is arranged on the fixing shaft and is rotated around the fixing shaft along with the rotary drum; the front end of the back centering drum is hinged with one end of the back spring; and a centering limiting structure is arranged between the front bracket of the fixing base and the front centering rotary drum and between the back bracket of the fixing base and the back centering rotary arm respectively. The mechanism has the characteristics of simple and compact structure, small occupied space, convenient adjustment, simple manufacture and low cost.

Description

technical field [0001] The invention mainly relates to the field of vehicle engineering, in particular to a return mechanism for vehicle steering. Background technique [0002] The return performance of the vehicle is an important part of the steering stability of the vehicle. It means that the steering wheel should automatically return to its position after turning, without deviation, and the steering wheel must not have shimmy or other abnormal phenomena. The steering return performance is not only related to the convenience of car driving and manipulation, but also has a direct impact on the safety of high-speed driving. A car that does not have the ability to return to the center, or does not return to the center, or a car that swings violently during the process of returning to the center, the driver and passengers are not satisfied. Generally, the steering wheel can be automatically returned to its position under the action of gravity and lateral force through the pos...
