An accelerator pedal assembly has a mounting bracket and a pedal arm mounted to the bracket for pivotal movement between an idle position and a full throttle position. A biasing mechanism extends between the pedal arm and the bracket for urging the pedal arm to the idle position. A friction disc engages the biasing mechanism for movement therewith. The friction disc is in frictional engagement with a stationary friction plate for relative movement therebetween. Movement of the pedal arm from the idle position towards the full throttle position responsively rotates the friction disc relative to the friction plate and the biasing mechanism responsively increases frictional engagement between the friction disc and the friction plate by urging the friction disc and friction plate together. |
