Abstract

The invention provides a detection device and a detection and adjustment method for an automobile axle maximum steering angle, and belongs to the field of automobile axle detection. The detection device comprises a support fixed to a steering knuckle, a laser transmitter and a machine vision system, wherein the steering knuckle is arranged at the end of the axle and rotationally connected with the axle, the laser transmitter is used for positioning the steering knuckle and arranged on the support, laser rays transmitted by the laser transmitter and the axial lead of the axle intersect with a rotary shaft of the steering knuckle, the laser rays transmitted by the laser transmitter and the axial lead of a flange of the steering knuckle are located on the same plane, the machine vision system is used for detecting the steering angle of the steering knuckle, and a camera shooting mechanism of the machine vision system faces towards the axle. The detection device for the automobile axle maximum steering angle is simple in structure, convenient to use, low in manufacturing cost, and capable of meeting the requirements of various axles for adjustment of the maximum steering angles.

Description

technical field [0001] The invention relates to the field of vehicle axle detection, in particular to a method for detecting and adjusting the maximum steering angle of the vehicle axle. Background technique [0002] When the direction of the car turns to the extreme left or right, the angle between the center plane of the car wheel, that is, the steering axis of the steering knuckle and the axle axis of the car, is the maximum steering angle, which determines the turning radius of the car The size of the car affects the stability, safety and comfort of the car. If the steering angle is adjusted too large, the lateral slip between the tire and the bottom surface will increase when the car turns, causing abnormal tire wear; if the steering angle is adjusted too small, it will be difficult for the car to turn when turning, and driving safety will be affected. Therefore, the maximum steering angle is an important technical parameter of the axle. [0003] The axis line of the ...
