摘要： A rotary wheel-end assembly (90) is provided that includes a disc-like member (26) that when secured to a vehicular wheel hub (16) is operative to rotate relative a stationary axle spindle as well as provide a first chamber (28) about the end of axle (2). Assembly (90) has a passageway (36) therethrough for conveying pressurized air to the tire from axle (2) and includes a cover (42) secured in spaced-apart relationship to a side of member (26) facing away from axle (2) to provide a second chamber (46). Chambers (28) and (46) are adapted to hold a lubricant for lubricating frictional interaction between rotary assembly (90) and stationary axle (2) as well as wheel bearings (12) and at least one opening (40) is provided through member (26) for providing fluid communication between chambers (28) and (46) in addition to the preferable inclusion of at least one resilient closable member (48) through cover (42) for conveying lubricant into chamber (46).

摘要： A method of establishing a target pressure for a vehicle tire for storage in a receiver having a microcontroller where a sensor/transmitter combination is mounted on each wheel. After each tire is inflated to the target pressure the sensor/transmitters are sequentially triggered to send an identification code and a target pressure signal to the receiver for storage in memory. In an alternate embodiment, the target tire pressures are statistically averaged and a warning signal is generated if a single tire target pressure deviates a predetermined amount from the statistical average.

摘要： A pressure relief valve (61) including a body (110, 114) interconnecting an inflatable volume (20a,22a) with a source of pressurized fluid (30) and the atmosphere. A pair of valve members (120, 122) cooperate to allow controlled inflation and deflation of the volumes (20a,22a) as well as to close off the fluid path between the source and the volumes and vent fluid from the volumes to the atmosphere in order to achieve at least two predetermined fluid pressures in the volume.

摘要： An apparatus and method for a vehicle central tire inflation system (CTIS) produces a series of valve open signals in response to a demand tire pressure signal in which each valve open signal has a time period and a time space occurs between each open signal. The series of open signals terminates when the current tire pressure is at least equal to the demand tire pressure and upon termination, a count is made of the number of valve open signals. In each successive series of valve open signals, the time period is increased or decreased depending upon whether the previous count is greater or less than a predetermined count range.

摘要： A central tire deflation system for emergency vehicles, such as fire trucks, rescue vehicles located at airports, enabling the operator to deflate all of the tires of the emergency vehicle to a predetermined minimum pressure while traveling to a crash site so that the "footprint" of the tires is increased at or about the time the vehicle reaches soft terrain. The minimum tire pressure is obtained by a minimum pressure valve which senses tire pressure as the tires are being deflated and stops deflation of the tires when the predetermined minimum pressure is sensed.
