A wheel end component monitoring system includes at least one wheel end component and an aggregator system operably connected to the at least one wheel end component. The wheel end component includes a component body and a sensor assembly configured to detect an input associated with the component body, output sensor data representative of the detected input, and transmit the sensor data. The aggregator system is configured to receive position information for the wheel end component from a user interface, receive identification information for the wheel end component from the wheel end component, associate the position information with the identification information for the wheel end component, receive the sensor data from the wheel end component, associate the sensor data with the position information for the wheel end component, and output the sensor data together with the associated position information for the wheel end component.

Wheel end component monitoring system and method

A brake chamber includes a chamber housing having an end, a push rod configured for reciprocal movement in the chamber housing in a first direction and a second direction over a stroke distance, a return spring disposed in the chamber housing configured to urge the push rod in the second direction and a sensor assembly having a sensor and a magnet movable relative to the sensor with movement of the push rod. The sensor is configured to detect a magnetic field strength of the magnet and output sensor data representative of the detected magnetic field strength. The sensor assembly is configured to determine a position of the push rod based on the sensor data over the entire stroke distance.

A vehicle braking system includes a piston rod extendable from an air brake chamber, a rotatable cam shaft, and a slack adjuster coupled to the piston rod and the cam shaft. The slack adjuster is configured to rotate the cam shaft as the piston rod extends. The slack adjuster has a control gear coupled to the cam shaft such that the control gear rotates as the cam shaft is rotated. A pinion gear meshes with the control gear such that the pinion gear rotates as the control gear rotates, and a take-off gear meshes with the pinion gear such that the take-off gear rotates as the control gear rotates. A magnet coupled to the take-off gear is configured to rotate as the take-off gear rotates. A sensor is configured to sense rotation of the magnet, and an indicator is configured to indicate brake stroke of the piston rod.

Vehicle braking systems with automatic slack adjusters

A brake drum for a vehicle braking system includes a closed end, an open end opposite the closed end, a braking wall axially extending between the open end and the closed end, and a compression device that applies a radial compressive force to the braking wall thereby increasing the thermo-mechanical fatigue resistance of the braking wall. A first restraining tab on the braking wall to axially restrain the compression device on the braking wall.

Vehicle brake drums having braking walls enhanced with compressive stresses

Spring failure detection systems include an air brake cylinder having a spring axially extending therein, a sensor coupled to the air brake cylinder and configured to sense forces applied to the air brake cylinder, an indicator coupled to the sensor and configured to indicate failure of the spring based on the forces sensed by the sensor, and a controller in communication with the sensor and configured to control the indicator. Methods for detecting failure of a spring are also disclosed.
