Abstract
A pneumatic rotary coupling (,) for an air pressure installation for one or more wheels of a vehicle, in which the wheel's axle (,) is used as the section of the pipe of the static installation, in accordance to the system of the coupling used. The coupling's stem (,) has one end formed in the shape of a nozzle which extends in the plane of the wheel, disposed as an axial extension of the wheel's axle end. The stem is located rotatable and slidable inside block (,) which is fixed to the wheel's hub cover. A cover (,) fixed to the block presents a cavity (,) with an edge that defines a seat for a plastic bushing (,) that supports the coupling's stem. The external surface of this bushing is conformed by grooves (,) that communicate the cavity towards the orifices linking with the tires. One method allows for the detection of bearing faults using the same coupling when the axial sliding of the stem is sufficient to vent the pressurized air.
