Problems solved by technology

[0005] The disadvantage of this solution is that a large number of components must be arranged in a narrow space, which results in correspondingly high manufacturing and installation costs

Embodiment Construction

[0060] exist figure 1 A conventionally constructed friction clutch 1 can be seen in the drawing. Housing 2 is connected in a rotationally fixed manner to a flywheel 3 (shown in dashed lines) of the internal combustion engine, housing 2 being rotatable about a common axis of rotation 4 . Alternatively, a dual-mass flywheel can also be provided as flywheel 3 , as is shown, for example, in DE 139 39 030 A1 or in DE 19820 503 A1. A pressure plate 5 is arranged in the housing 2 in a rotationally fixed manner but axially displaceable, which pressure plate 5 has a wear compensation device 15 in the exemplary embodiment shown here. A clutch disc 7 (not shown) with a friction lining 6 is arranged between the pressure plate 5 and the flywheel 3 . In this case, the friction lining 6 has a friction surface 6 which cooperates with a corresponding counter-friction surface on the flywheel 3 and on the pressure plate 5 in the engaged state for the transmission of torque. A diaphragm spring...

Abstract

A friction clutch has an outer housing; a compaction plate which is axially-movable but can not rotate in the outer housing; a clutch driven disk for at least one friction wafer lining surface is disposed between the compaction plate and a flywheel friction surface; a diaphragm spring which has a manipulate tongue and can apply the compaction force of the load applied to the friction wafer to the compaction plate and is support on a support area of the outer housing; a holding element which extends from the outer housing, directly or indirectly positions the diaphragm spring relative to the outer housing, passes the pass area of the manipulate tongue and is mounted in radial internal part; a support element disposed with a support area, the diaphragm spring is support in the support area during releasing process, the support element is fixed by the holding element relative to the diaphragm spring and is abutted to the diaphragm spring in the support area under pretightening force; and protrusions for extending toward the holding element in radial direction, and these protrusions are supported on the manipulate tongue.

Description

technical field [0001] The invention relates to a friction clutch, in particular for motor vehicles, which has a housing which is rotationally connected to a flywheel about a common axis of rotation and to an internal combustion engine; but axially displaceable pressure plate; a clutch plate with at least one friction lining between said pressure plate and the friction surface of said flywheel; a diaphragm spring with An actuating tongue formed thereon for deflecting the diaphragm spring around its support region, which can act on the pressure plate with a pressure for applying a load to the friction lining lining force and is supported on a support area configured on the housing; extending from the housing, directly or indirectly positioning the diaphragm spring relative to the housing, passing through the operating tongue and a retaining element mounted radially inside; a support element with a bearing section on which the diaphragm spring rests during disengagement, wherei...
