A brake wear monitoring system

Abstract

The invention provides a brake abrasion monitoring system, and belongs to the technical field of abrasion monitoring systems. The system solves the problem of how to accurately and comprehensively monitor the abrasion of a brake. The system comprises a data acquisition unit, a friction plate abrasion amount monitoring unit and a brake disc / drum abrasion amount monitoring unit, and further comprises an identification unit and a compensation unit, wherein the identification unit is used for forming a voltage signal variable by comparing the initial voltage according to a real-time received abrasion thickness voltage signal and judging the replacement situation of a friction plate and a brake disc or a brake drum through a voltage variable signal, and the compensation unit is used for enabling an original initial voltage signal difference to be used as an operation compensation value of the initial voltage signal of the current friction plate and the abrasion amount of the friction platethickness. According to the brake abrasion monitoring system, accuracy of the friction plate data of the brake under different conditions is guaranteed, the initial voltage difference is used as the calculation of the abrasion thickness of the brake disc or the brake drum when the friction plate is replaced, and monitoring of the abrasion amount of the brake disc or the brake drum is effectively identified, so that accurate and comprehensive monitoring of the abrasion amount of the brake is realized.

Description

technical field [0001] The invention belongs to the technical field of wear monitoring systems, and relates to a brake wear monitoring system. Background technique [0002] Cars often use friction plates to force the car to slow down and stop. Therefore, the friction plates become thinner and thinner. When the wear reaches the limit, they must be replaced. If it is not replaced in time, it will bring hidden dangers to driving safety. Although the car needs to be inspected and repaired every year, the conditions of use of the car are different. Driving habits such as stepping on and braking hard will cause the friction lining to wear out quickly, and personal maintenance habits are different. In addition to the wear of the friction lining, the brake may also involve to brake disc / drum wear. Although existing automobiles are equipped with wear limit alarms for friction linings, probes are generally installed on brake shoes or brake blocks to detect the wear of friction linin...
