Abstract

A friction clutch with at least a clutch cover, at least a pressure plate connected with it non-rotatably, though axially being limitedly displaceable, as well as an actuation means effective between said clutch cover and the pressure plate for axial force-exertion on the pressure plate.

Claims (15)

1 . A friction clutch comprising:

a clutch cover;

a pressure plate non-rotatably connected with the clutch cover, wherein the pressure plate is limitedly axially displaceable;

an actuation means operatively arranged between the clutch cover and the pressure plate arranged to exert axially directed force on the pressure plate; and,

at least a constituent component part having a plurality of recesses arranged to receive a plurality of screw elements, wherein the screw elements are arranged to balance the friction clutch when fixedly received within the plurality of recesses.

2 . The friction clutch recited in claim 1 , wherein the plurality of recesses are arranged in a plurality of groups distributed along the circumference of the friction clutch.

3 . The friction clutch recited in claim 1 , wherein each of the plurality of screw elements includes a threaded section that automatically taps the screw thread.

4 . The friction clutch recited in claim 1 , wherein the clutch cover includes a plurality of recesses arranged to receive the plurality of screw elements.

5 . The friction clutch recited in claim 1 , wherein the clutch cover includes a plurality of radially protruding regions on its outer circumference, having a plurality of recesses arranged to receive a plurality of screw elements arranged to be screwed in axially.

6 . The friction clutch recited in claim 1 , wherein the plurality of screw elements find application with different weights.

7 . The friction clutch recited in claim 1 , wherein each of the plurality of screw elements includes a threaded section and an adjoining screw head, forming a balancing weight, with a socket for a screw-driving tool.

8 . The friction clutch recited in claim 1 arranged as a twin clutch with a clutch cover that can be coupled with a driving flywheel, and a connection cover that can be coupled with a pressure plate of the clutch, wherein a pressure plate respectively is assigned to a clutch which can be pressed by actuation means, which are effective between the clutch cover and said two pressure plates and at least one of the covers featuring recesses for receiving screw elements used as balancing weight.

8 . The friction clutch recited in claim 1 , wherein a second clutch cover is axially at least partially arranged within a connection cover and includes a plurality radially protruding regions along its circumference in which recesses distributed in circumferential direction are provided for receiving the screw elements.

9 . The friction clutch recited in claim 1 , wherein a connection cover forms a plurality of axially extending lobes on its outer circumference which form fastening regions for coupling with a pressure plate and radial regions of the clutch cover, with respect to the circumferential direction of the friction clutch, are provided respectively between two such lobes.

10 . The friction clutch recited in claim 1 , wherein the plurality of recesses are arranged in a plurality of radial regions of the clutch cover opposite the outer fictitious enveloping surface of the connection cover are disposed radially in such a manner that they are at least axially accessible even in a mounted state of the twin clutch.
