Abstract

The invention discloses a wheel flange wear closed -loop management system and method, which solves the problems of wheel flange wear of a vehicle and untimely noise control. The method comprises thefollowing steps of lubricating a wheel flange according to a lubricating period and a lubricating frequency, and measuring real-time wheel profile information. Performing wheel set equivalent conicityanalysis on the wheel profile information to obtain the equivalent conicity, when the equivalent conicity is greater than a first threshold value, running in a speed reduction mode, and when the equivalent conicity is greater than a second threshold value but smaller than the first threshold value, performing emergent lubricating. The lubricating period is used for determining the lubricating time under a non-emergent lubricating condition, and the lubricating frequency is used for determining the number of times of lubricating within the lubricating period. The system comprises a lubricatingcontrol module for setting the lubricating frequency and the lubricating period, a lubricating system for lubricating, a laser measurement device for detecting and sending the wheel profile information, and a vehicle speed control system for performing running operation in a speed reduction mode.

Description

technical field [0001] The present application relates to the technical field of rail transit equipment, and in particular to a closed-loop management system and method for wheel rim wear. Background technique [0002] As a heavy-duty public transportation tool, how to provide passengers with a more comfortable riding experience and reduce the cost of use is the main direction of research. Studies have shown that as a special form of rail transit products, the wheel rim relationship is an important factor that directly affects the safety and comfort of vehicle operation. At the same time, various contact forms of wheel rims will produce different types of noise and different types of rim wear. The mutual wear of the rims will lead to changes in the equivalent taper of the rim contact. When the change reaches a certain limit, it will affect the safety of the vehicle operation. The usual method is to monitor the wear condition manually, and implement regular maintenance after ...
