B60C 23/02 - Signalling devices actuated by tyre pressure
A pneumatic lift axle control system includes a plurality of valves configured to receive first fluid pressure from a first fluid supply and to receive second fluid pressure from a second fluid supply, and to selectively communicate the first fluid pressure or the second fluid pressure as a pilot signal to a lift axle actuator valve.
A rotary union is configured for removable disposition into the central bore of a hubcap through an orifice in the outboard face of the hubcap. The hubcap includes a fluid channel extending from the central bore to the exterior of the hubcap. The rotary union includes a port through which fluid may flow into the fluid channel when the rotary union is disposed in the central bore.

DIGITAL WHEEL END ASSEMBLY TEMPERATURE MONITORING SYSTEM
A wheel end high-temperature warning system for a vehicle having a wheel-end assembly mounted to an axle is described. The system may include a first temperature sensor including a sensor head configured for mounting within a spindle section of the wheel end assembly, the sensor head in a heat exchange relationship with a bearings of the wheel-end assembly. The system may further include a transmitter disposed on the axle to which the wheel-end assembly is mounted, the transmitter being configured to receive a first sensor signal from the first temperature sensor indicative of a wheel-end temperature and transmit the signal to a receiver. A vehicle data acquisition module may be coupled to the receiver, the data acquisition system being programmed to receive the first sensor signal and process the signal to determine a measured temperature of the spindle.

A central tire inflation system for maintaining tire inflation on a vehicle is provided. The central tire inflation system includes a rotary union assembly having a housing that is coupled to and rotates with the hubcap. The housing is rotationally coupled to a stationary shaft. A flexible torque transfer shaft is connected to the stationary shaft on one end and to an axle plug on the other end. The axle plug has a hub forming a bore where the hub is movable on a web of material. The flexible torque transfer shaft and hub have cooperative non-circular shapes to resist rotation. An air vent is provided in the rotary union assembly that is isolated from the lubrication area, which inhibits the pressurized air from the central tire inflation system from pressurizing the lubrication area.
A tire-inflation system for a small trailer may include a fluid pressure source mountable to the trailer, and air conduits providing sealed fluid communication between the air pressure source and the small trailer's pneumatic tires.
