## Abstract

An end disk of a multi-disk clutch is described, which has a ring plate, the ring plate having a central opening and at least one axial impression on a front side via which a corresponding projection is formed on the opposite front side.

## Claims

### Claim 1

An end disk of a multi-disk clutch, the end disk having a ring plate which has a central opening and at least one axial impression on one front side, via which a corresponding projection is formed on the opposite front side.

### Claim 2 (depends on 1)

The end disk according to claim 1, wherein an impression and an associated projection run annularly around the opening.

### Claim 3 (depends on 2)

The end disk according to claim 2, wherein the impression and the associated projection run centrically to the central axis of the end disk.

### Claim 4 (depends on 2)

The end disk according to claim 2, wherein a plurality of radially spaced apart circumferential, annular impressions and associated projections are provided.

### Claim 5 (depends on 4)

The end disk according to claim 4, wherein the impressions are concentric with each other.

### Claim 6 (depends on 1)

The end disk according to claim 1, wherein a plurality of circumferentially spaced apart impressions and associated projections are provided.

### Claim 7 (depends on 6)

The end disk according to claim 6, wherein the impressions and the corresponding projections thereof form circular or oval surfaces.

### Claim 8 (depends on 7)

The end disk according to claim 7, wherein the oval surfaces have their respective longitudinal central axis oriented obliquely to a respective radially extending straight line intersecting the longitudinal central axis.

### Claim 9 (depends on 1)

The end disk according to claim 1, wherein all projections define a plane outer surface arranged in a radial plane to the central axis of the end disk.

### Claim 10

An assembly of a plurality of end disks of a multi-disk clutch, each end disk having a ring plate which has a central opening and at least one axial impression on one front side, via which a corresponding projection is formed on the opposite front side, the end disks being made of sheet metal and each having the same sheet metal wall thickness, the axial extension of the projections being different when comparing the end disks with each other.

### Claim 11 (depends on 10)

The assembly according to claim 10, wherein the end disks have identical geometries except for the different axial extension of the projections and the corresponding different axial depth of the impressions.

### Claim 12

A method of manufacturing an assembly of a plurality of end disks of a multi-disk clutch, each end disk having a ring plate which has a central opening and at least one axial impression on one front side, via which a corresponding projection is formed on the opposite front side, the end disks being made of sheet metal and each having the same sheet metal wall thickness, the axial extension of the projections being different when comparing the end disks with each other, characterized by the following steps:
providing ring plates of sheet metal, which all have the same sheet metal wall thickness and the same external dimensions, and
manufacturing of end disks differing in their axial disk thickness by producing impressions of different depths and thus projections which differ in their axial extent by means of a forming tool, in particular always by means of the same forming tool which penetrates the end disks at different depths.
