A transmitter for a synchronizing 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 synchronizing 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.

Transmitter for a synchronising assembly of a manual transmission and a method for producing a transmitter

A synchronizer ring for a synchronization unit of a manual transmission has a ring axis and is formed of a ring-shaped sheet-metal cone with a substantially constant sheet thickness. The ring-shaped sheet-metal cone has a cone-shaped radial outer side and an opposite radial inner side with a cone-shaped friction surface, wherein on its radial outer side the sheet-metal cone includes an integrally molded centering collar for radially centering the synchronizer ring relative to a synchronizer hub of the synchronization unit. The sheet-metal cone is deformed in the region of the centering collar and includes a first sheet portion with a residual thickness reduced as compared to the sheet thickness and axially adjacent a second sheet portion with a collar thickness which at least corresponds to the sheet thickness. The residual thickness of the sheet-metal cone is substantially constant in the first sheet portion.
