RDS/radial 2L rear axle for tractors

The RDS/radial is the perfect system for comfortably adjusting tyre inflation while on the move. It is suited for all tractors with full-floating axles.

In principle, the system works by transferring air from a stationary component (stator) to a rotating component (rotor). For this process to work, pressure-resistant rotary seals are installed in the stator that together with the rotor form annular channels through which the air pressure flows, of course, also while the vehicle is moving.

The stator is bolted onto the axle housing aligned with the axle centerline the rotor sits lined up with the stator on the axle shaft and is secured using a clamping fastener. Both a working line and a small control line rotate synchronously with the rotor and are led to the tyre valve.

The air supply comes from the vehicle’s own compressor and an air reservoir of the braking system. A brake priority valve, the so-called overflow valve, sees to it that the pressure in the air brake reservoir cannot fall below 6.5 bar (94 psi) so that the brakes have priority over the tyre inflation system.

The patented two-line principle ensures that after every pressure change the tyre is closed off and all rotary joints (including rotary seals) are depressurized, thereby sparing the system from unnecessary wear. This technology also ensures that the tyre loses no air in the event of a leak in the regulating system or a break in the line, thereby guaranteeing increased safety.

In the rim, a wheel valve with check functionality is installed that will immediately close in the event a line tears and will keep the tyre from losing pressure.

Operating the RDS/radial is done simply and comfortably from the cab controller of the digital control system or the ISOBUS terminal of the tractor.

The adjustable tyre pressures for work in the field and on the road are selected at the push of a button for all tyres connected to the system. After activating the system, all selected tyre pressure values in every tyre are automatically adjusted and once that is complete, the system turns itself off. The system can, of course, be turned off at any time at the push of a button.
