Abstract:
An accelerator pedal assembly comprising:a mounting bracket, a pedal arm mounted to the bracket for pivotal movement between an idle position and a full throttle position, a biasing mechanism extending between the pedal arm and the bracket for urging said pedal arm to the idle position, said biasing mechanism comprises a coil having a first and second ends with said second end engaging the mounting bracket, a stationary friction plate, a first friction disc engaging said first end of said coil for movement therewith, said first friction disc in frictional engagement with said friction plate, a second friction disc engaging said second end of said coil, said second friction disc frictionally engaging said pedal arm, wherein movement of said pedal arm from said idle position towards said full throttle position responsively rotates said first friction disc relative to said friction plate and said biasing mechanism responsively increases friction engagement between the first friction disc and the friction plate and said movement of said pedal arm winds said coil to axially extend said coil urging said first friction disc axially and thereby effect said increase in frictional engagement between said first friction disc and said friction plate.
