    RDS/radial

    2 line tyre regulation system for tractors with bar axles

     

    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.

    RDS/radial rear axle & AIRBOX/drive front axle

    2 line tyre inflation system for tractors with full-floating axles and stub axles

     

    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 RDS/radial and AIRBOX/drive system work by transferring air from a stationary component (stator) to a rotating component (rotor). For this process to work, pressure-resilient gasket seals are installed in the stator that in interacting with the rotor cause annular channels through which the air pressure flows, of course, also while the vehicle is moving.

     

    At the rear axle, the stator is screwed onto the axle-funnel concentrically to the middle axle; the rotor sits lined up with the stator on the axle shaft and is secured using a clamping fastener. Both a large line and a small control line rotate synchronously with the rotor and are led to the tyre valve.

     

    At the front axle, the rotary joint is bolted onto the wheel studs concentrically to the middle axle using a fitting stirrup. Rotor and stator are embedded lined up with one another. Both a large line and a small control line rotate synchronously with the rotor and are led to the tyre valve.

     

    The air lines at the front axle run over the fender through a telescopic tube and are 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 and the control line are connected to the rotary joints using quick-action couplings so that they can be easily removed when not in use and placed on the fenders in dummy couplers.

     

    The rotary joints and the entire air line system at the front and rear axles are pressurized only during an active control cycle. The patented two-line principle ensures that after every pressure change the tyre is closed off and all transfer units (including gasket seals) are depressurized, thereby sparing the system from unnecessary wear.  This technology also sees to it 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.

     

    The air supply comes from the vehicle’s own compressor and an air reservoir of the braking system.  A brake safety 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.

     

    In the rim, a tyre valve with a non-return finger device 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 control console of the digital control 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.

    In the rim, a tyre valve with a non-return finger device is installed that will immediately close in the event a line tears and will keep the tyre from losing pressure.

     

    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.

Systems for Adjusting Tyre Pressure when Stationary

  • AIRBOOSTER® Systems for Adjusting Tyre Pressure when Stationary  mehr >>

    AIRBOOSTER®

    Tyre inflation and fast deflation set for all tractors and vehicles

     

    The AIRBOOSTER® is a transportable and extremely robust system for quickly adjusting tyre pressure when the vehicle is stationary. The user can adjust tyre pressure very quickly using the handheld device included (pressure gange with ball valve and attachments), making this the ideal product for everyone who is looking to change or check their tyre pressure only occasionally as well as for anyone looking to first try out the advantages of driving with adjusted tyre pressure without making a larger investment.

     

    The PTG screw-on coupling with protective cap is screwed on and mounted to the tyre valve after the valve core has been removed (larger opening for the air to pass through).

     

    Quick deflator in action:

    pressure control with 1/10 bar (1.5 psi) precision, deflation in a matter of seconds!

     

    The red hose coupling for the trailer brake connection is an air tap not subject to approval by the technical inspection authorities (TÜV) for fast inflation anywhere.

     

    The filling hose is inserted using a plug nipple into the hose coupling, but can also be connected to any shop compressor.

     

    The securely mounted pressure limitation valve in the filling hose (see arrow) serves as a pressure safety valve when inflating the tyre and prevents in the worst case the tyre from exploding and possible personal and property damage! This is why inflating the tyre is only allowed when using the filling hose.

    AIRBOX/mobil plus

    Transportable tyre inflation system for all tractors and vehicles

     

    The AIRBOX/mobil plus is a transportable system for quickly adjusting tyre pressure when the vehicle is stationary. Unlike the AIRBOOSTER, the AIRBOX/mobil plus has its own, complete control unit integrated into the case. Adjusting the tyre pressure axle by axle is possible without the need of monitoring the system. Simply connect the control unit to the air brake system, set the desired tyre pressure and connect the two spiral hoses to the tyres. The device will then take care of the rest. In the meantime, you can prepare the machine and implement for the next job.

     

    The patented PTG screw-on nipple is screwed onto the tyre valve once, after the valve core has been removed (larger opening for the air to pass through).

     

    The hose coupling for the trailer brake connection is an air tap not subject to approval by the German registration authorities (TÜV) for fast inflation anywhere.

     

    The filling hose is inserted into the hose coupling, but can also be connected to any shop compressor.
