  • Patent number: 9873419
    Abstract: 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.

  • Patent number: 9855940
    Abstract: A vehicle brake monitor assembly for an air disk brake includes a brake actuator having a pushrod projecting from inside a chamber of said brake actuator. The pushrod releasably actuates a lever arm of a caliper thereby moving the disk brake into a braking position when the pushrod is in an extended position and releasing the disk brake from the braking position when the pushrod is in a retracted position. The pushrod includes a pushrod shaft and a contact member biased in a telescoping relationship relative to the pushrod shaft and the lever arm of the caliper abuts the contact member counteracting the bias of the contact member. A sensor is integrated with the assembly proximate the contact member and detects movement of the pushrod relative to the lever arm and to the pushrod shaft.

  • Patent number: 8994523
    Abstract: A brake monitoring system and method for a vehicle having multiple axles and a plurality of brake actuators and an engine control module, each brake actuator being associated with one of the axle. The system include sensors for measuring, in real-time, brake pressure and brake lining wear, and generating first and second signals. The first and second signals are received and stored in a chassis communications module. The chassis communications module detects fault condition of the brakes as a function of the first and/or second signals and for recording the fault condition, the fault condition being one of a brake monitor warning and a brake lining warning and provides an indication of status via warning lights.
