  • Pressurized wheel hub system
    Patent number: 7740036
    Abstract: A system for pressurizing wheel hub formed from an air-tight sealing arrangement located on each end of a wheel hub to form a closed air system in the interior of the wheel hub. The closed air system fluidly coupled to a DC power air compressor or pressurized air tank for receiving pressurized air. A pressure gauge provides a visual indication of the air pressure in the closed air system whereby a breached seal condition within the wheel hub can be detected.
