Abstract

A method for manufacturing a clutch body for a synchronizing device of a transmission includes the steps of:

• • a) providing an externally toothed clutch disk,
  • b) providing a counterfriction ring,
  • c) applying a friction lining onto the counterfriction ring,
  • d) establishing a non-releasable connection between the clutch disk and the counterfriction ring, and
  • e) upsetting a portion of the counterfriction ring at least partly provided with the friction lining in radially inwardly facing direction, so that a counterfriction cone is formed, which is provided for cooperation with a friction surface of the synchronizer ring.

Claims

1. :

A method for manufacturing a clutch body for a synchronizing device of a transmission, comprising the steps of;

a) providing an externally toothed clutch disk which is provided for cooperation with a sliding sleeve,

b) providing a counterfriction ring which is provided for cooperation with a synchronizer ring,

c) applying a friction lining onto the counterfriction ring,

d) establishing a non-releasable connection between the clutch disk and the counterfriction ring, and

e) upsetting a portion of the counterfriction ring at least partly provided with the friction lining in radially inwardly facing direction, so that a counterfriction cone is formed, which is provided for cooperation with a friction surface of the synchronizer ring.

2. :

The method according to claim 1, wherein in method step c) the friction lining is applied onto an external shell surface of the counterfriction ring in a circumferentially closed manner.

3. :

The method according to claim 1, wherein the counterfriction ring provided in method step b) has an at least sectionally circularly cylindrical tubular shape.

4. :

The method according to claim 1, wherein the clutch disk and the counterfriction ring include form elements for establishing a non-releasable positive connection.

5. :

The method according to claim 4, wherein the counterfriction ring includes axially projecting protrusions which after establishing the non-releasable connection according to method step d) engage into recesses formed on the clutch disk.

6. :

The method according to claim 5, wherein the recesses are circumferentially closed, axially continuous windows in the clutch disk.

7. :

The method according to claim 1, wherein clutch disk and counterfriction ring are connected with each other by flow molding, caulking, riveting and/or welding.

8. :

The method according to claim 1, wherein the clutch disk includes at least one abutment surface which is provided for supporting the counterfriction ring on the clutch disk in a radially inwardly facing direction.

9. :

The method according to claim 1, wherein the steps c) and d) are carried out one after the other in the indicated order.
