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.

Brake monitoring assembly for a rail system

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.

Electronic stroke sensor for air disc brake

A brake actuator assembly for an air disk brake includes an actuator housing having a pushrod that is extensible from the actuator housing. A lever arm is disposed inside a caliper housing. The lever arm is actuated by the pushrod for transferring motion from the actuator to a brake pad. A sensor element is disposed between the actuator housing and the caliper housing with the sensor element being sealably engaged to the actuator housing providing an air tight enclosure between the caliper housing and the actuator. An inspection port is disposed in the sensor element providing access to receive a visual sensor and a pressure sensor for identifying a condition of the brake actuator and for identifying a condition of the air tight enclosure.

Electronic stroke sensor for air disc brake with inspection port

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.
