Abstract (en)
[origin: WO2012071579A1] 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.
