Abstract

In a plate clutch, an annular cylinder chamber with a moveable annular cylinder portion is located in a transition region between a radial flange and a cylindrical external plate carrier integral with the radial flange. The position of the annular cylinder portion is fixed in the radial and axial directions relative to the external plate carrier by the flange which fixes the annular cylinder in one axial direction of the clutch axis and by means of a circlip in the other axial direction of the clutch axis. In order to improve the sealing of the working pressure chamber enclosed by the annular cylinder portion, the annular cylinder is supported in the radial directions by means of a ring seal, so that it can move and be also elastically carried on the external plate carrier.

Claims8

Dependent claims

A plate clutch assembly comprising an annular cylinder chamber;

an annular cylinder portion means mounted in a transition region of the annular cylinder chamber to define in part the annular cylinder chamber between a radial flange means of the annular cylinder chamber and cylindrical external clutch plate carrier means of the annular cylinder chamber;
said cylindrical external clutch plate carrier means being integral with the radial flange means;
means for axial positioning of the annular cylinder portion means relative to the external clutch plate carrier means including the radial flange means which prohibits movement of the annular cylinder portion in one axial direction of an axis of the clutch and a circlip prohibiting movement in an opposite axial direction of an axis of the clutch;
and where the annular cylinder portion means is supported against movement in an outward radial direction from the axis of the clutch by means of an elastic ring seal so that the annular cylinder portion means can be elastically supported on the external clutch plate carrier of the annular cylindrical chamber.
