ABSTRACT:
A compressed air passage system carried by an axle on a road vehicle for nsferring compressed air from/to a central air pressure source to/from the associated vehicle wheel. The passage system comprises a specially-constructed duct installable in a clearance space between the axle housing and axle; an air transfer slip ring mechanism is arranged at the outer end of the duct to transfer compressed air across the interface between the non-rotating and rotating parts of the axle assembly. The system is specially designed to permit the air passage system to be added to a pre-existing axle construction with minimum modification of existing components.
