Gas-pedal module
First Claim
1. A gas pedal lever module comprising:
- (a) a gas pedal lever having a journal intermediate the ends thereof to enable pivotal movement of the pedal lever about a pivot axis;
(b) a bearing element having an upwardly facing circumferential surface operably supporting the pedal lever journal, and providing clearance for movement of the journal in the upward direction away from the circumferential surface, the journal and the bearing element having a cooperatively shaped contact surface;
(c) an idling stop and a full load stop positioned to provide a selected range of pivotal movement of the journal within the bearing element and the full load stop to provide a pivot point causing the journal to raise from the bearing element when the gas pedal lever is moved beyond the preselected journal pivot range; and
(d) a pedal-lever position sensor which produces an electric signal corresponding to the pedal lever position.

Abstract
A gas-pedal module has a gas pedal (12) which is mounted pivotably in a housing and can be actuated, counter to a restoring spring, with pedal-force-dependent hysteresis, a pedal-position sensor producing an electric signal corresponding to the pedal position. In view of the high pedal forces, precise and expensive bearings are necessary in order to avoid jamming of the gas pedal (12). In order to reduce the production costs arid nevertheless reliably to prevent jamming, it is proposed to mount the gas pedal (12) in a floating manner in a bearing element (28) which has play in the upward direction. Specific selection of the coefficient of friction on the contact surface (30) between the bearing journal (18) and the bearing element (28) makes it possible to achieve a hysteresis as is desired in the case of such gas-pedal modules.
