  • Patent number: 6407526
    Abstract: Some automobiles have mechanisms for adjusting the height of accelerator and brake pedals, and any clutch pedal, so that drivers large and small can adjust the pedals to the best height. All pedals are adjusted by a single reversible electric motor having a shaft connected directly or by a flexible shaft to the adjusting mechanisms. If any fault develops in any mechanism, the pedals may not be adjusted to the same height, which is hazardous to the driver. A safety switching system detects any serious misalignment of the pedals and de-energizes the motor. The system comprises separate switches which are operable by adjustment of the pedals, and are electrically connected in series with the power supply circuit for the motor. When the pedals are aligned, the bridging contactors of the switches are aligned and are effective to maintain the electrical continuity of the motor circuit. Each contactor has three contact sliders which successively engage staggered tabs on contact strips for the respective pedals.

  • Patent number: 6041673
    Abstract: A dual function throttle control system is disclosed for earthmoving machines. The throttle control system includes a hand lever that is electrically connected to a proportional directional hydraulic valve. Rotation of the hand lever controls actuation of an engine speed actuator and thus the speed of the engine. A foot pedal is connected through a three position spring-centered hydraulic valve to the engine speed actuator. The direction of flow of hydraulic fluid through the three position spring-centered hydraulic valve is controlled by the position of the hand lever. When the hand lever is set at the lowest speed setting, rotation of the foot pedal in a first direction increases the engine speed. When the control lever is set at the highest speed setting, rotation of the foot pedal in the first direction decreases the speed of the engine. Thus, the foot pedal operates both as a decelerator or an accelerator depending on the position of the hand lever.

The actuator component of the control arrangement is in the shape and general configuration of a trigger. Together, the trigger and handle assembly are ergonomically styled to form fit the hand. The trigger is spring loaded to provide initial resistance to movement and to return the trigger to its original position as applied pressure is released. The trigger is mechanically coupled to a potentiometer device housed in the handle assembly. As the trigger position is changed by the vehicle operator, the resulting movement of the potentiometer produces a control signal having a variable output voltage that is used by a control mechanism to change the engine throttle position. Thus, the subject invention provides a secondary method of accelerating an automotive vehicle from a stopped position.

  • Patent number: 4712443
    Abstract: An override mechanism is disclosed for connection between the accelerator pedal of a vehicle and the fuel supply for normally enabling the driver to adjust the fuel supply but which can be overriden by speed limiting means. The throttle pedal is connected to move a lever to increase the fuel supply. This lever is pivoted to a clamp member via a shaft. The clamp member is clamped to a shaft whose angular movement adjusts the fuel supply. A spring resists pivoting movement of the lever with respect to the clamp member and therefore movement of the pedal is normally transmitted direct to the clamp and adjust the fuel supply. However, when the speed reaches an upper limit, an actuator pulls on a cable which is clamped to a part rigid with the clamp. Therefore the part moves relative to the cable carrier and the lever against the force of the spring. The clamp therefore closes the fuel supply.

  • Patent number: 4603752
    Abstract: A speed and direction control apparatus for a skid steer vehicle of the type having right and left driven wheels which are caused to be operated by variable displacement pumps. The control apparatus is similar to that found in normal highway vehicles in that a steering wheel is provided for controlling the turning of the vehicle and a foot pedal is provided for controlling the speed of the vehicle. One end of each of a pair of push-pull control cable assemblies is used to move the control arms of the variable displacement pumps and the other end of the pair of control cables are in turn secured to a rotatable element which is in turn supported for rotation on a portion of a rotatable steering column. The rotatable element can be rotated by the steering wheel to cause one control arm to be displaced with respect to the other control arm to effect turning of the vehicle.

  • Patent number: 4553626
    Abstract: A speed control mechanism for a hydrostatically driven vehicle such as a street sweeper is disclosed which includes a selector lever. When the lever is in a variable engine speed position, depression of an accelerator pedal progressively opens the engine throttle from idle speed to high engine speed and progressively closes an inching valve thereby enabling the operator to comfortably drive the vehicle through stop and go traffic. When the lever is in a governor controlled high speed position, the engine throttle is opened and the engine is driven at high speed under control of the governor, and progressive depression of the throttle progressively closes the inching valve thereby providing optimum power while the vehicle is working, such as sweeping streets, with the speed of the vehicle being controlled by the position of the throttle and the position of the inching valve.
