Problems solved by technology

[0004] Usually, the performance of the wheel speed sensor sample (such as the accuracy and stability of the output signal of the wheel speed sensor) needs to be tested during the mass production process or after the production is completed before it is officially put into use. In general, what the general operator can see is only the processing procedure rather than the design drawing, so it is impossible to accurately determine the installation position of the wheel speed sensor
During the test, the difference in the installation position of the wheel speed sensor will cause the change of its output signal (such as output current or voltage), and the influence of the difference in the installation position on the output current or voltage has been ignored in the prior art

Abstract

The invention relates to a position adjusting method of a wheel speed sensor. The method is applied to a performance test process of the wheel speed sensor so as to adjust an installation position ofthe wheel speed sensor relative to a test gear ring. The method comprises the following steps: building a wheel speed sensor test platform, and completing wiring preparation work among all modules ofthe test platform, wherein a wheel speed sensor is installed at the initial position relative to a test gear ring; rotating the test ring gear relative to the wheel speed sensor to output a sensor signal from the wheel speed sensor; and adjusting the installation position of the wheel speed sensor relative to the test gear ring according to the sensor signal output from the wheel speed sensor so as to determine the optimal installation position. The invention further relates to a position adjusting device of the corresponding wheel speed sensor and wheel speed sensor performance detection equipment comprising the position adjusting device.

Description

technical field [0001] The present invention relates to the field of wheel speed sensors, more specifically, the present invention relates to a method for adjusting the position of the wheel speed sensor during testing, a position adjusting device and performance testing equipment including the position adjusting device. Background technique [0002] The wheel speed sensor is one of the essential sensors in the vehicle, and it plays a vital role in the electronic stability system (ESP) and anti-lock braking system (ABS) of the vehicle. The wheel speed sensor is matched and designed by R&D designers according to the vehicle structure, which is suitable for the chassis shape of the specific model, the size of the axle shaft and the ring gear, the position selected for reading the ring gear, etc., the installation position and installation method of the general wheel speed sensor (including reading position, air gap distance and fixed position of the head bushing, etc.) are mar...
