Abstract
An electronic accelerator pedal assembly for vehicles including a base bracket adapted to be secured to the floor pan and having an upper housing fixedly supporting the associated electronic componentry indicating accelerator pedal position, including the output wiring free from the hostile environment zone beneath the accelerator pedal. The accelerator pedal is hingedly connected to the basic bracket member at a lower end and rotatably and slidably coupled to a spring biased follower member at its upper end by a jointly radiating coupling, and the follower member transmits pedal travel to the electronic componentry and includes a stop member for retaining the accelerator pedal in idle position.
Claims11
An accelerator pedal assembly adapted to be installed as a completely assembled and pre-adjusted assembly onto the floor of a vehicle cab comprising:
- a base bracket member;
- a housing portion carried by said base bracket member at one end thereof;
- an elongate accelerator pedal rotatably secured to said base bracket member at the opposite end thereof;
- electronic means secured to said housing portion for producing an electrically generated output signal in proportion to the location of said accelerator pedal in any position from an idle position to the wide open throttle position;
- follower means secured to and extending between said accelerator pedal and said electronic means;
- said housing portion being supported by said base bracket member in an elevated position located above the upper extremities of said accelerator pedal, whereby the electronic means will be free of particulates or other contaminants commonly carried by the accelerator pedal or otherwise transferred to the pedal assembly by the operator;
- said electronic means including a rotary potentiometer having a rotary input shaft extending laterally of said base bracket member and said accelerator pedal;
- and
- said follower means including an arm member fixedly coupled at one end to said rotary input shaft and slidingly coupled at the opposite end thereof to said accelerator pedal.

- a base bracket member;
- a housing portion carried by said base bracket member at one end thereof;
- an elongate accelerator pedal rotatably secured to said base bracket member at the opposite end thereof;
- electronic mans secured to said housing portion for producing an electrically generated output signal in proportion to the location of said accelerator pedal in any position from an idle position to the wide open throttle position;
- follower means secured to and extending between said accelerator pedal and said electronic means;
- said housing portion being supported by said base bracket member in an elevated position located above the upper extremities of said accelerator pedal, whereby the electronic means will be free of particulates or other contaminants commonly carried by the accelerator pedal or otherwise transferred to the pedal assembly by the operator;
- said accelerator pedal being secured at one end to said base bracket member by a hinge having an axis extending laterally of said base bracket member, and being biased in an uppermost position representing the idle position of said accelerator pedal;
- and
- said electronic means including a rotary potentiometer having an input shaft with an axis disposed laterally of said base bracket member;
- said follower means being coupled to said input shaft and adapted to oscillate about said input shaft axis between one position representing the idle position of said accelerator pedal and a second position representing the wide open throttle position of said accelerator pedal;
- and
- said follower means being fixed to the free end of said accelerator pedal by a jointly radiating coupling means for providing linearly proportionate travel between said follower means and said accelerator pedal, whereby a specific degree of accelerator pedal travel at any and every pedal position between idle and wide open throttle will cause a specific degree of oscillation in said follower means and thus a constant electrical output from said potentiometer regardless of the specific pedal position of said accelerator pedal.
