  • Patent number: 9110493
    Abstract: A device, sometimes referred to as a clutch brake warning indicator, that provides feedback, which may be tactile, audible or visual, to the vehicle operator as the clutch pedal is nearing the point of its stroke where the clutch brake will be engaged. In use, the feedback clutch brake warning indicator will assist the driver against applying the clutch brake during shifting operations, which can cause severe damage to the clutch.

  • Patent number: 6283483
    Abstract: A system is provided for use on a vehicle (10) which allows the relative angle of turn between a first steerable wheel (20) and a second steerable wheel (22) to be established by use of a tie rod assembly (32) which is variable in length. The tie rod assembly (32) includes a hydraulic cylinder assembly to vary the length by introducing or removing pressurized hydraulic fluid. A spring (120) is provided to establish a predetermined length to the tie rod assembly should the hydraulic system fail. The length of the tie rod assembly is controlled by an electronic control (166) which is provided with data from angle sensors (160,162) at each of these steerable wheels. The electronic control can be provided with an electronic table of relative angles for the wheel members and can adjust the length of the tie rod appropriately. The device allows for establishing the desired relationship between the wheel members at any turn angle.
