A control lever assembly in the form of a foot pedal includes a pedal arm pivotally mounted on a shaft supported on a base or bracket, and a helical spring for returning the arm to a home position. Lateral displacement of the spring during loading thereof is prevented through the use of either a mechanical stop engaging one side of the spring or eccentric mounting of the spring on relative to shaft.

An integrated throttle position validation sensor includes electrically independent throttle position and position validation components responsive to a single mechanical input applied to a protective sensor housing. By suitable mounting to the throttle control device, the mechanical input corresponds to accelerator pedal position. Within the sensor housing a potentiometer moves with the mechanical input whereby a variable voltage throttle position signal is generated. Also, within the housing a separate validation switch responsive to the mechanical input provides an independent representation of throttle control device position in the form of, for example, a bi-state validation signal. The sensor integrates previous separate throttle control position and position validation functions into a single environmentally secure housing which requires no calibration. The integrated sensor is more reliable and less costly than previously available separate throttle control and idle validation functions.

An accelerator foot pedal suspended from a support structure affixed to the front wall of a vehicle cab, a drum at the proximal end of the foot pedal defining, with the support structure, an enclosure which houses an internal rack-and-pinion gearing. A sensor mounted to the support structure generates a control signal representing the angular position of the foot pedal, the rack and pinion translating rotational movement of the foot pedal to an input of the sensor.

Foot pedal arrangement for electronic throttle control of truck engines

An electronic foot pedal for diesel engine control systems. The pedal provides a voltage signal to a diesel engine electronic fuel control system in response to the drivers demand for engine power. Disclosed is an accelerator pedal assembly containing a potentiometer and pedal interfacing components which provide a voltage signal proportional to pedal position. The pedal assembly is an integral unit which is cab mounted and connected to the engine fuel control via an appropriate wiring harness. An idle stop pin provides a positive pedal idle position. When the idle stop pin is removed, the bias spring load forcing the pedal toward idle is relieved allowing easy assembly of the device.
