Abstract
A pressurized 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 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.
Claims11
A pressurized wheel hub comprising:
- a wheel hub having bearings that are rotatably securable to an axle;
- seals between said wheel hub and said axle, said seals forming a closed air space around said bearings;
- means for fluidly coupling said closed air space to a source of pressurized air, said source of pressurized air maintaining between 1 psi and 30 psi in said closed air space.
4 The pressurized wheel hub of claim 3, wherein said air pressure gauge includes a dial face and a pressure indicating needle moving relative to said dial face in direct relation to the air pressure within said closed air system.
5 The pressurized wheel hub of claim 3, wherein said air pressure gauge includes a color coded dial face capable of indicating safe operation of the wheel hub.
The pressurized wheel hub of claim 5, wherein said air pressure gauge is fluidly coupled to said pressurized wheel hub aperture.
