BRAKE MONITORING ASSEMBLY FOR A RAIL SYSTEM

摘要

A brake monitoring assembly and method for monitoring a brake system of a train includes a plurality of train bogeys supporting each train car, each bogey having a wheel axle supporting wheels engaging a train track. Each wheel axle includes a tread brake and a disc brake. A tread brake actuator includes an extendable tread brake pushrod for actuating the tread brake. A disc brake actuator includes an extendable disc brake pushrod for actuating the disc brake. A pneumatic system provides pneumatic pressure for actuating the brakes and includes a sensor for monitoring pressure. Each brake actuator includes a sensor for detecting length of extension of a pushrod. A controller identifies a condition of the actuators when the pressure detected by the sensor is inconsistent with a length of extension of any of the pushrods and signals an indicator for indicating a condition of the actuators.

1. A brake monitoring assembly for a train having a train engine and a plurality of interconnected cars supported on a track, comprising:
a plurality of train bogeys supporting each of said train cars, each of said train bogeys including a wheel axle having opposing wheels engaging the train track, said wheel axle including a tread brake and a disc brake; a tread brake actuator having an extendable tread brake pushrod for actuating said tread brake and a disc brake actuator having an extendable disc brake pushrod for actuating said disc brake; a pneumatic system for providing pneumatic pressure to said tread brake actuator for actuating said tread brake and providing pneumatic pressure to said disc brake actuator for actuating said disc brake with the pneumatic pressure being monitored by a pneumatic sensor assembly; a tread brake actuator sensor for detecting a length of extension of said tread brake pushrod and a disc brake actuator sensor for detecting a length of extension of said disc brake pushrod; a controller electronically connected to said tread bake actuator sensor, said disc brake actuator sensor, and said pneumatic sensor assembly for detecting a fault condition of said tread brake actuator and said disc brake actuator when the pneumatic pressure detected by said pneumatic sensor is inconsistent with a length of extension of said tread bake pushrod or said disc brake pushrod; and an indicator for indicating a condition of the tread brake actuator and the disc brake actuator.
