The invention provides a calibrating device of a steering angle measuring instrument, which is characterized in that a base is arranged, a rotary table which has standard rotation angle scale and can rotate around a pin is symmetrically arranged at the two ends of the base, a vertical plate is fixedly arranged on the rotary table, the steering angle measuring instrument is fixedly arranged on the vertical plate by a fixing skeleton provided with a locating pin. The invention can realize calibration to the steering angle measuring instrument of a car, thus ensuring the accuracy of the steering angle measuring instrument of the car; the device has the advantages of simple structure, small space usage, flexible operation and high calibration degree, being capable of simulating the knuckles of different steering angles.
Description
technical field [0001] The invention relates to a calibration device, more specifically a device for calibrating a steering angle measuring instrument of an automobile front axle. Background technique [0002] The steering angle of the front wheels of a car refers to the angle when the front wheels turn to the left or right to the limit position, which not only affects the driving stability of the car, but also has a certain influence on the wear and tear of the tires. Because the steering angle is too large, the lateral slip between the tires and the ground will be increased when the car turns, and the tires, fenders, and straight tie rods may be worn. If the steering angle is too small, the turning radius of the car will increase, making it difficult for the car to turn, and driving safety will be affected. Therefore, the steering angle should be checked and adjusted according to the regulations of the original automobile manufacturer. [0003] figure 1 Shown is the car...
