A dynamic annular seal chamber is also provided. The annular seal chamber is disposed radially between the spindle and the rotatable part. The fluid conduit and the fluid passage are in fluid communication with each other through the annular seal chamber. The annular seal chamber is disposed axially between a first volume and a second volume. The first volume and the second volume are in fluid communication with each other through at least one fluid channel for leading fluid leaked out of the annular seal chamber and leaked into the first volume and/or into the second volume through the fluid channel.

  • Patent number: 8869850
    Abstract: An automatic onboard drive axle tire inflation system configured for use in vehicles having an articulating joint, including but not limited to drive axles that include a steerable axle and a vertically movable wheel such as used in independent suspension systems. Various embodiments of the invention deliver pressurized air from an inner axle to an outer axle, such as through a CV joint, which embodiments can withstand the significant heating generated by braking systems. One preferred embodiment includes a flexible tube extending from an inner drive axle to an outer drive axle, wherein the tube maintains a seal there between, and articulates in one or both drive axles to accommodate the varying distance and angle therebetween during the steering of the associated wheel. The system can be employed in any vehicle including an automobile, truck and tractor.

  • Patent number: 8757232
    Abstract: Systems for monitoring and adjusting the air pressure in a rotating wheel in air-tight connection with a non-rotating axle. In one embodiment, a non-rotating tank air pressure system is separated from a wheel air pressure system by a fill-purge valve. Manipulating the fill-purge valve changes the air pressure in the wheel air pressure system, while the wheel may be rotating, and the change in air pressure is monitored by a gauge.
