  • Patent number: 9670978
    Abstract: A vehicle brake circuit including a brake actuator, a manually operable valve, an electrically operable valve and a fluid reservoir for the supply of fluid to the actuator. The manually operated valve may be connected to the fluid reservoir either directly or indirectly through the electrically operable valve, when its position blocks a direct fluid connection with the fluid reservoir. The electrically operated valve controls activation or deactivation of the actuator except when the mechanically operated valve is in an unblocked position and overrides the electrically operated valves control of the actuator.

  • Patent number: 9469285
    Abstract: A brake arrangement for a vehicle having a cardan brake and separate left and right brakes. The left brake activated by movement of a first lever and the right brake is activated by movement of a second lever. The left brake, right brake and the cardan brake are activated together by movement of both levers together, characterized in that the cardan brake is connected to a fluid supply in a circuit which comprises a first and a second brake valve arranged in series and the first brake valve is operable by the first lever and the second brake valve is operable by the second lever.

  • Patent number: 9248705
    Abstract: A tire inflation feed arrangement for a tire 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 axially outwardly facing surface between the seals. A first of these annular chambers is connectable with pressurized air to inflate the associated tire and the second annular chamber is connectable with pressurized air to operate a valve mounted on the wheel for admitting air into the tire from the first annular chamber or exhausting air from the tire.

  • Patent number: 8979216
    Abstract: A vehicle power braking system has separate left and right brakes (11, 12) operable from a source of pressurized fluid (13) via relay valve means (16) controlled by separate left and right brake operating pedals (14, 15) to provide steering assistance during a turn. The relay valve means delivers a brake operating pressure proportional to the depression of the associated brake operating pedal to separate left and right shift valves (17, 18), each shift valve being connected with its respective operating pedal (14, 15) by a respective pilot line (19, 20) so that when each pedal is operated the associated shift valve is opened by the respective pilot line pressure to supply the proportional pressure from the relay valve means to the respective brake (11, 12).

  • Publication number: 20130284281
    Abstract: 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.

  • Patent number: 8469157
    Abstract: A brake assembly is provided for a utility vehicle. After a brake operation, a clearance between a control member and an intermediate part and/or between a brake element and an intermediate part is adjusted by means of a displacement or restoring unit arranged in an intermediate part. Wear, and the associated change of clearance, can be compensated for by means of friction gripping devices, located respectively in the control member and in the brake element.

  • Publication number: 20120247860
    Abstract: A vehicle has an engine (10) which drives wheels (16,24) of the vehicle via a CVT (11). 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.

  • Publication number: 20110120817
    Abstract: The invention relates to a brake assembly for a utility vehicle. After a braking operation a clearance between a control member (11) and the intermediate part (13) and/or between a brake element (12) and the intermediate part (13) is adjusted by means of a displacement unit (2) arranged in the intermediate part (13). Any change in wear and therefore any resulting change in clearance can be compensated for by means of a respective tensioning device (15, 15?), respectively located in the control member (11) and in the brake element (12), each of which are connected to the displacement unit (2).
