The method of detecting the clearance angle of the steering system by specifying the steering force

Abstract

The method for detecting the clearance angle of the steering system by the steering force is stipulated. The steering wheel on one side of the steering shaft stops on the ground plane, and the two sides of the steering wheel are clamped to limit its steering. The steering wheel on the other side can rotate without restriction. Install on the steering wheel Steering force-angle tester, slowly turn the tester in one direction to the specified larger steering force or steering torque, measure the steering angle B1 of the steering wheel, and then measure the steering angle B2 of the steering wheel in the opposite direction, absolute value |B1‑B2| is equal to the steering system clearance angle B under the specified steering force or steering torque. When the free rotation angle A of the steering wheel is detected, the steering transmission mechanism clearance angle C=B‑A can be calculated. During the entire steering force increase process In , the clamped steering wheel does not rotate, and the measured C contains a small amount of wheel deformation.

[0002] The automobile steering system is divided into two mechanism components, one is the steering wheel mechanism component, and the other is the steering transmission mechanism component. The clearance angle of the automobile steering system is the sum of the free rotation angle of the steering wheel and the clearance angle of the steering transmission mechanism. The technology adopts sub-component detection, one is to detect the free rotation angle of the steering wheel, and the steering force on the steering wheel is very small; the other is to detect the clearance angle of the steering transmission mechanism by applying a lateral loading force to the steering wheel, and there is no specified load For a reversible steering gear, a small lateral loading force will cause the steering wheel to rotate, and it is difficult to detect the clearance angle of the steering transmission mechanism under the action of a large specified force
