Abstract

A clutch pedal (1) for a vehicle, in particular, a motor vehicle, includes at least one side plate (2a, 2b) mounted for rotation spindle (3) connectable to the bulkhead of the vehicle. A peg (5) is fixed to one end of a pedal web (4) and slides in a first slot (21) provided in the side plate. A movement mechanism (7) causes the peg to slide in the slot, defining a length (L) between the rotation spindle of the side plate and the other end of the pedal web. A stud (8) is mounted in the side plate (2a) at a distance (R) from the rotation spindle, for receiving the end of the rod of the clutch mechanism of the vehicle. The clutch pedal operates to provide a constant step-down ratio (L/R).

Claims

1. An adjustable clutch pedal for a vehicle, comprising at least one side plate mounted for rotation about a rotation spindle and connectable to a bulkhead of the vehicle, a pedal web having a peg fixed to a first end and slidably received in a first slot in the side plate, a movement mechanism for causing the peg to slide in the first slot and defining a length (L) between the rotation spindle of the side plate and a second end of the pedal web, a stud mounted in the side plate at a distance (R) from the rotation spindle, for receiving an end of a rod of a clutch mechanism associated with the vehicle, and a link rod having a first end secured to the pedal web and a second end secured to a cam, wherein the cam has a second slot for slidingly receiving the stud, and wherein the side plate includes a third slot for receiving the stud and for causing translation of the stud to obtain a constant step-down ratio (L/R).

2. The pedal of claim 1 wherein the movement mechanism includes an angled reduction gearbox coupled to a worm which slidingly receives a nut secured to the pedal web.

3. The pedal of claim 2 wherein the worm and the angled reduction gearbox are fixed to a face of the side plate.

4. The pedal of claim 1 wherein the link rod is secured directly to the pedal web by the peg.

5. The pedal of claim 1 wherein the cam is secured directly to the side plate by a pivot connection.

6. The pedal of claim 1 wherein the side plate further includes a reinforced peg for receiving an assistance spring.

7. A pedalbox module for a motor vehicle, comprising an adjustable clutch pedal including at least one side plate mounted for rotation about a rotation spindle and connectable to a bulkhead of the vehicle, a pedal web having a peg fixed to a first end and slidably received in a first slot in the side plate, a movement mechanism for causing the peg to slide in the first slot and defining a length (L) between the rotation spindle of the side plate and a second end of the pedal web, a stud mounted in the side plate at a distance (R) from the rotation spindle, for receiving an end of a rod of a clutch mechanism associated with the vehicle, and a link rod having a first end secured to the pedal web and a second end secured to a cam, wherein the cam has a second slot for slidingly receiving the stud, and wherein the side plate includes a third slot for receiving the stud and for causing translation of the stud to obtain a constant step-down ratio (L/R).

8. The pedalbox module of claim 7 which further includes a brake pedal having a movement mechanism for achieving a spatial movement which is the same as a spatial movement achieved for the clutch pedal.

9. The pedalbox module of claim 7 wherein the movement mechanism includes an angled reduction gearbox coupled to a worm which slidingly receives a nut secured to the pedal web.

10. The pedalbox module of claim 9 wherein the worm and the angled reduction gearbox are fixed to a face of the side plate.

11. The pedalbox module of claim 7 wherein the link rod is secured directly to the pedal web by the peg.

12. The pedalbox module of claim 7 wherein the cam is secured directly to the side plate by a pivot connection.

13. The pedalbox module of claim 7 wherein the side plate includes a reinforced peg for receiving an assistance spring.
