- a pressure plate for a friction clutch of a motor vehicle is known, which is read on the preamble of claim 1.
- the pressure plate is viewed in the axial direction of the pressure plate substantially annular and divided into a plurality of circumferentially of the pressure plate arranged successively and with respect to each other at least partially displaceable Anpressplattensegmenten.
- the circumferential direction is in a normal plane, that is, in a plane pierced at right angles by a vector of the axial direction.
- Two contact pressure plate segments adjacent in the circumferential direction have two end faces facing one another, which are connected to one another by a connecting device extending in the normal plane, wherein one of the two contact plate segments has a hammerhead-shaped recess essentially corresponding to a contour of the connecting device and receiving the connecting device.
- Such a construction of the pressure plate makes it possible to produce the pressure plate from individual sheet metal segments which can be punched out without excessive punching waste. At the same time, such a pressure plate makes it possible to compensate for unevenness during operation of the friction clutch and to reduce the cupping / shielding, that is to say the deformation of the pressure plate which, due to the introduced thermal energy, is caused by the expansion of the friction surface of the pressure plate facing the clutch disc The duration of time required for this introduced heat energy to spread over the entire volume of the pressure plate arises. It is an object of the present invention to provide a pressure plate for a friction clutch and a corresponding friction clutch, which are inexpensive and reliable to produce, and in which at the same time the Topfung can be reduced.

Since the recess has a uniform width measured in the normal plane, or the width measured in the normal plane decreases starting from the end face of the pressure plate segment into the interior of the pressure plate segment, it is possible to produce the individual pressure plate segments in a cost-effective and reliable manner Pressure plate is inexpensive and reliable to produce. In particular, hammerhead-shaped recesses and connecting devices can be dispensed with, which favors punching technology production.
- the mutually facing end faces are spaced apart from one another, at least in the circumferential direction, by a gap-shaped intermediate space.
- the gap-shaped interspace can be used to ensure that the individual pressure plate segments are relieved to a limited extent. tive to each other, which favors the compensation of unevenness and the reduction of the Topfung the pressure plate.
- the gap-shaped gap preferably includes the entire end faces, that is also the contour of the connecting device and the recess, but may also relate exclusively to the circumferentially facing each other, in particular straight, portions of the adjacent pressure plate segments.
- the recess has a central axis, and the central axis has a non-concentric with respect to a center of rotation of the pressure plate course.
- no additional fastening means are required to hold the individual Anpressplattensegmente relative to each other permanently in position or to allow a limited displaceability of the individual Anpressplattensegmente each other.
- the central axis has at least one direction change. Particularly by means of a hook-shaped or meander-shaped contour of the recess and the corresponding connecting device, a reliable positioning of the pressure plate segments relative to one another or the limited displaceability of the pressure plate segments relative to each other is made possible.
- the change of direction includes an angle greater than 45 °.
- all contact plate segments of the pressure plate each have a first end face with a projecting in the direction of each adjacent Anpressplattensegments connecting device and a second end face with a corresponding, extending into the interior of this respective pressure plate segment recess.
