Abstract

A transmitter for a synchronising assembly of a manual transmission has a transmitter disk and at least one clutch disk which is arranged on a side surface of the transmitter disk. The clutch disk and the transmitter disk are fixedly connected together by local welding points. A method for producing a transmitter for a synchronising assembly of a manual transmission consists of providing a clutch disk and a transmitter disk. Then, the clutch disk and the transmitter disk are fastened together by means of projection welding. Finally, the thus formed assembly is hardened.

First claim

1 . A transmitter for a synchronising assembly of a manual transmission, having a transmitter disk and at least one clutch disk which is arranged on a side surface of the transmitter disk, wherein the clutch disk and the transmitter disk are fixedly connected together by local welding points.

2 . The transmitter of claim 1 wherein projections are provided which form the welding points.

3 . The transmitter of claim 2 wherein spacers are provided, on which the projections are formed.

4 . The transmitter of claim 2 wherein spacers are provided on the transmitter disk, on which the projections are formed.

5 . The transmitter of claim 1 wherein four spacers are provided between a clutch disk and the transmitter disk.

6 . The transmitter of claim 3 wherein four spacers are provided between a clutch disk and the transmitter disk.

7 . The transmitter of claim 4 wherein four spacers are provided between a clutch disk and the transmitter disk.

8 . A method for producing a transmitter for a synchronising assembly of a manual transmission by means of the following steps:
a clutch disk and a transmitter disk are provided; the clutch disk and the transmitter disk are fastened together by means of projection welding; the thus formed assembly is hardened.

9 . The method of claim 5 wherein the assembly is freely hardened.

10 . The method of claim 5 wherein the assembly is hardened on a mandrel.

11 . The method of claim 5 wherein the transmitter disk is provided with at least one recess, a pressure piece being mounted in the recess after the assembly has been hardened.

12 . The method of claim 8 wherein the pressure piece is clipped into the recess.

13 . The method of claim 5 wherein the pressure piece is provided with a base part and a guide part, wherein the base part is located between two clutch disks which are arranged on sides of the transmitter disk facing away from each other, and in that the guide part is guided in the axial direction between edges of the recess which are opposite one another in the circumferential direction.
