摘要： A tyre inflation feed arrangement for a tyre supported on a wheel carried by a wheel rim rotatably mounted via a wheel hub on an axially outer end of an axle housing. The feed arrangement has an annular support body surrounding the outer end of the axle housing, and three concentric annular seals extending around an axially outwardly facing surface on the support body to seal two concentric annular chambers formed in the axial!y outwardly facing surface between the seals. A first of these annular chambers is connectable with pressurised air to inflate the associated tyre and the second annular chamber is connectable with pressurised air to operate a valve mounted on the wheel for admitting air into the tyre from the first annular chamber or exhausting air from the tyre. The annular seals are each mounted in a respective annular groove in the axially facing surface and each groove is also connectable with a source of pressurised air to press the seals against an annular contact surface on the wheel hub to seal the first and second annular chambers when the tyre is being inflated. The wheel hub is provided with first receiving means which open through the annular contact surface to receive air from the first annular chamber and conduct such air to the tyre and second receiving means which also opens through the annular contact surface to receive air from the second annular chamber and conduct such air to the valve mounted on the wheel. The support body is mounted on the axle housing in a location radially within bolts which attach the wheel to the hub to reduce the rubbing speed of the seals on the contact surface to reducing wear caused by the contact pressure of the seals.

摘要： A vehicle has an engine ( 10) which drives wheels ( 16,24) of the vehicle via a CVT ( 1 1). The vehicle also has a driver operated braking system which brakes wheels of the vehicle, and an electronic control system (28,60) which, in the event of deceleration of the vehicle, detects when the driven wheels are about to lock and increases the currently operative CVT ratio to allow the locking wheels to speed up towards a rotational speed corresponding with the current vehicle speed whilst ensuring that any braking operation selected by the driver is maintained subject to the avoidance of wheel locking. The CVT is of the hydrostatic/mechanical power split type and the braking system includes an anti-lock braking (ABS) function which can provide the wheel speed and vehicle speed values and prevent wheel locking under braking.

摘要： A tyre inflation control system for a tractor (10) has an inflation means (13) for inflating and deflating tyres (11, 12) of the tractor. Conduits (14,15) connect the inflation means (13) with the tyres, and a control means (20) connected with the inflation means is provided for storing predetermined tyre pressure levels and initiating the changing of the inflation pressure of the tyres between the predetermined pressure levels set in the control means. The predetermined tyre pressure levels can conveniently correspond to a field work pressure level and a road work pressure level and the control means can store inflation pressures for the tyres of both the tractor (10) and any associated trailer (16) or machine being towed by the tractor. The control means may include an electronic display monitor (20a) with a touch sensitive screen through which the predetermined levels of tyre pressure can be entered.
