摘要： A rotary union assembly for use in an automatic tire inflation system for maintaining the desired pressure in the tires on a tractor trailer or other vehicle having pressurized axles. The assembly communicates the valve stems on a pair of adjacent tires with the axle interior through the use of a flexible tube extending between a stationary first fitting threadably engaged in the axle spindle and a rotary housing secured against the outside end surface of the hub cap so as to be positioned exteriorly of the wheel lubrication compartment and rotatable with the hub cap. The first fitting defines an open channel extending axially therethrough and includes an o-ring seal extending about the channel and forming an airtight seal within the fitting about the tube. A stationary shaft member having an air passageway extending axially therethrough carries the downstream end of the flexible tube and projects into the rotatable housing to communicate the axle interior with the housing through the flexible tube and provide a rotatable mounting for the housing on the shaft. The shaft defines a stationary bearing surface on its downstream end. A rotary sealing member having an air passageway extending axially therethrough is mounted within the housing for rotation therewith. The rotary sealing member defines a rotary bearing surface which is urged the stationary bearing surface on the shaft member by a spring member. Opposed channels are provided in the housing proximate the bearing surfaces and hose and valve assemblies communicate the opposed channels with the tire valve stems.

摘要： An expansion plug filter assembly adapted to be mounted in an axle spindle for communicating filtered air from an axle to a rotary union assembly in a tire inflation system. The assembly includes a head portion, a body portion, an internal air flow channel extending longitudinally through the head and body portions. A press plate cavity is provided in the head portion of the assembly. A filter unit is carried by the body portion and a press plate is disposed within the press plate cavity. An o-ring mounted in a groove about the head portion provides an airtight seal between the head portion and the interior of the axle spindle. Tightening a plurality of securement bolts embedded in the head portion draws the press plate into the press plate cavity and causes a downstream portion of the head portion of the assembly to expand against the spindle to releasably secure the assembly within the spindle such that air passing therethrough is first caused to flow through the filter unit.

摘要： A failure tolerant tire inflation system for supplying pressurized air from an onboard source to the vehicle tires in the event of a pressure drop in one or more of the tires below a predetermined level. The system includes a tire inflation valve communicable with the source of pressurized air, a tire selector valve assembly for selectively communicating air from the tire inflation valve with the vehicle tires, a plurality of valve assemblies each communicating with at least one tire and selectively communicating with the tire selector valve assembly. A controller selectively activates and deactivates the tire inflation valve and valve assemblies to sequentially check the pressure in the tires and direct air to any underinflated tire. A transducer is provided for detecting the tire pressure levels upon the opening of the valve assembly communicating with that tire and communicating the underinflated condition to the controller.
