A sheet-metal synchronizer ring for a synchronizing device has a conical ring body, an outer toothing for blocking the axial movement of a sliding sleeve, and at least one indexing tab which is bent in the axial direction and limits the rotation of the synchronizer ring in a synchronizer hub. The indexing tab has a tab widened portion on at least one side.

Synchronizer ring made of sheet metal

A synchronizer ring () having a support body (), a conical friction surface (), and a friction layer () of a material including carbon fibers applied to the friction surface (). The material is a compacted carbon fiber reinforced plastic. A synchronizer ring of this type has a longer service life than those of the prior art, on account of the improved dimensional stability of the friction layer, and is inexpensive. Also disclosed is a method for producing the above-described synchronizer ring.
