Abstract

A clutch having a pressure plate ( 1 ) and a counter plate ( 16 ) is provided, with the pressure plate being displaceable by a clutch actuating mechanism such that a clutch disk can be clamped between the pressure plate and counter plate. The pressure plate is a multi-piece pressure plate having a central body ( 1 ) which includes a friction surface and on which at least one connecting element ( 5 ) is located, which protrudes beyond the friction surface and is connected to the clutch actuating mechanism for burst optimization and cost savings purposes.

Claims (20)

1. A clutch comprising a pressure plate and counter plate, the pressure plate is displaceable by a clutch actuation mechanism for clamping a clutch disk between the pressure plate and counter plate, the clutch actuation mechanism is located on a side of the pressure plate that includes a friction face, the pressure plate is a multiple-part pressure plate that has a central body that comprises the friction face and a back face, and is assembled with at least one connection element that projects radially past a circumferential edge of the pressure plate and the friction face and that attaches to the back face of the pressure plate, and is in connection with the clutch actuation mechanism, the at least one connection element includes two areas arranged in a radial direction and one area arranged in an axial direction, wherein an inner one of the radial areas has a first contact face that abuts and is secured to the back face of the pressure plate and an outer one of the radial areas has a second contact face that abuts and is secured to the clutch actuation mechanism, wherein a projection as a wear stop is arranged on the axially oriented area of the at least one connection element, and the wear stop contacts the counter plate in a maximum wear state.

2. The clutch according to claim 1 , wherein the central body has a rotationally symmetric construction.

3. The clutch according to claim 2 , wherein the central body is a cast body.

4. The clutch according to claim 1 , wherein a plurality of the connection elements are provided.

5. The clutch according to claim 1 , wherein each of the at least one connection elements comprises an angle having a z-shape that is affixed, riveted or screwed, on the central body or are assembled with the central body using a positive-fit and/or material-fit connection.

6. The clutch according to claim 5 , wherein each of the angles contacts a side of the pressure plate facing away from the clutch disk.

7. The clutch according to claim 5 , wherein each of the angles are made from sheet metal.

8. The clutch according to claim 5 , wherein each of the angles have one or more reinforcing sections.

9. The clutch according to claim 1 , wherein a plurality of the connection elements are arranged distributed along a periphery of the central body, which is rotationally symmetric.

10. The clutch according to claim 1 , wherein the central body is a ring body.

11. A clutch comprising a pressure plate and counter plate, the pressure plate is displaceable by a clutch actuation mechanism for clamping a clutch disk between the pressure plate and counter plate, the clutch actuation mechanism is located on a side of the pressure plate that includes a friction face, the pressure plate is a multiple-part pressure plate that has a central body that comprises the friction face and a back face, and is assembled with at least one connection element that projects radially past a circumferential edge of the pressure plate and the friction face and that attaches to the back face of the pressure plate, and is in connection with the clutch actuation mechanism, the at least one connection element includes two areas arranged in a radial direction and one area arranged in an axial direction, wherein an inner one of the radial areas has a first contact face that abuts and is secured to the back face of the pressure plate and an outer one of the radial areas has a second contact face that abuts and is secured to the clutch actuation mechanism, further comprising a tie rod that has an attachment area connected to the at least one connection element and in active connection with a plate spring of the clutch actuation mechanism.

12. The clutch according to claim 11 , wherein the central body has a rotationally symmetric construction.

13. The clutch according to claim 11 , wherein the central body is a cast body.

14. The clutch according to claim 11 , wherein a plurality of the connection elements are provided.

15. The clutch according to claim 11 , wherein each of the at least one connection elements comprises an angle having a z-shape that is affixed, riveted or screwed, on the central body or are assembled with the central body using a positive-fit and/or material-fit connection.

16. The clutch according to claim 15 , wherein each of the angles contacts a side of the pressure plate facing away from the clutch disk.

17. The clutch according to claim 15 , wherein each of the angles are made from sheet metal.

18. The clutch according to claim 15 , wherein each of the angles have one or more reinforcing sections.

19. The clutch according to claim 11 , wherein a plurality of the connection elements are arranged distributed along a periphery of the central body, which is rotationally symmetric.

20. The clutch according to claim 11 , wherein the central body is a ring body.
