Abstract

The invention discloses a clutch master cylinder detection method and device. The method comprises the following steps of putting a clutch master cylinder on a support frame, and fixing the clutch master cylinder through a fixing mechanism; sealing and plugging an air hole of the clutch master cylinder by using a sealing and plugging mechanism so as to perform sealing; performing electronificationby connecting an electrifying mechanism with an electric connection opening of the clutch master cylinder; simulating an automobile push rod by using a loading mechanism; loading the clutch master cylinder in a magnetic field interference mode to obtain a change curve of the output pulse duty ratio of a Hall sensor in the clutch master cylinder and magnetic field displacement; setting a thresholdvalue of the output pulse duty ratio of the Hall sensor; analyzing the change curve within the threshold value range; and judging whether the clutch master cylinder is qualified or not. The clutch master cylinder detection method and device have the advantages that whether the clutch master cylinder is qualified or not can be judged; the automation degree of the detection can be improved; and inaddition, the characteristics of high efficiency and high precision are realized.

Description

technical field [0001] The invention relates to the technical field of automatic detection, in particular to a method and device for detecting a clutch master cylinder. Background technique [0002] The automobile clutch master cylinder is installed between the clutch booster and the pedal, and is an important part of the clutch control mechanism. Its performance has a great influence on the braking performance of the clutch. [0003] At present, the method of using a differential pressure sensor to detect the clutch master cylinder is the most commonly used method in China to detect whether leakage occurs within a specified time. Time-consuming, labor-intensive, and highly dependent shortcomings. [0004] Based on this, the present application provides a detection system that uses electrical characteristics to detect the tightness of the clutch master cylinder. This system can not only improve the automation of detection, but also has the characteristics of high efficien...
