In principle, the AIRBOX/drive 1 line technology works by transferring air from a stationary component, the stator, to a rotating component, the rotor. For this process to work, pressure resilient gasket seals are installed in the stator. Together with the rotor, they form annular channels through which the air pressure flows, even while the vehicle is moving.
The rotary joint is screwed onto the wheel studs concentrically to the middle axle using a fitting stirrup. The rotor and stator are embedded and lined up with one another. Both a large line and a small control line rotate synchronously with the rotor and are led to the tire valve.
A ball valve is mounted in the rim and must be closed by hand after the vehicle has been parked.
The system is connected via a safety valve to the air brake system, so that 6.5 bar (94 psi) of pressure supply in the air brake reservoir is guaranteed at all times.
The air line at the rear axle runs over the fender through a telescopic tube and is led to the middle of the wheel. Using the telescopic tube, the clearance to the side of the rotating wheel can be individually adjusted.
The large line is connected to the rotary joints using couplings, so it can be easily removed when not in use and placed on the fenders in dummy couplers.
Operating the AIRBOX/drive 1 line technology is done simply and comfortably using the switch control console in the cab.
