ETC PEDAL

摘要

A pedal assembly having a hysteresis creating configuration in communication with a sensor of a pedal assembly. The assembly includes a housing and a pedal arm wherein the pedal arm is pivotally mounted by bushings to the housing. A connector and sensor assembly is provided connected through the pivot point (hub) where the pedal arm connects to the housing of the pedal assembly. A spring connects to a spring carrier wherein the spring is depressed upon depression of the pedal arm of the pedal assembly. As the spring applies a force to the spring carrier, the spring carrier slides down an inclined wall and applies a force to a friction shoe. The friction shoe is in contact with the generally circular hub of the pedal arm thus providing a hysteresis effect as the friction shoe contacts the hub of the pedal arm.

1. An electronic throttle control pedal assembly for use with a vehicle producing hysteresis, the assembly comprising:
a housing having an angled wall; a pedal arm pivotally connected to the housing, the pedal arm having an outer surface; and a hysteresis subassembly mounted to the housing, the hysteresis subassembly having a friction shoe and a spring carrier both mounted to the housing, the spring carrier configured to slide along the angled wall, the outer surface of the pedal arm in contact with an outer surface of the friction shoe, the hysteresis subassembly having at least one spring mounted between the spring carrier and the pedal arm; wherein as the pedal arm is depressed, the spring displaces the spring carrier along the angled wall which in turn pushes the friction shoe against the pedal arm as the pedal arm continues to rotate thereby creating friction and thus creating hysteresis between the angled surface and the spring carrier and between the friction shoe and the pedal arm.
