MAINTENANCE TIMING DETECTION MECHANISM OF BRAKE CONTROLLING DEVICE FOR RAILWAY VEHICLE

摘要

PROBLEM TO BE SOLVED: To improve detection accuracy of maintenance timing by restraining detection error of the maintenance timing according to actuation environment and conditions at the time of actuating a brake.;SOLUTION: This mechanism comprises a first brake cylinder pressure detector 19a detecting first brake cylinder pressure of a first brake cylinder 7a, a second brake cylinder detector 19b detecting second brake cylinder pressure of a second brake cylinder 7b, and a judging part 34a, into which signals detected by the first brake cylinder pressure detector 19a and the second brake cylinder pressure detector 19b are inputted. The judging part 34a detects the maintenance timing and transmits maintenance signals based on the signals detected by the first brake cylinder pressure detector 19a and the second brake cylinder pressure detector 19b when a condition that pressure difference between both of the brake cylinder pressures is beyond a predetermined value occurs predetermined times.;COPYRIGHT: (C)2006,JPO&NCIPI
