Abstract
In a synchronizing device for transmission assemblies, a gear shaft includes a detent mounted thereon in a twist-proof manner and at least one speed wheel cooperating with the detent and rotatable on the gear shaft by movement of a sliding sleeve. A clutch is connected in a shape-locking manner to the speed wheel and a synchronizing ring enabling engagable and disengagable friction coupling of the clutch with the detent. The synchronizing ring including a conically-shaped coupling surface and the friction coupling including a friction ring body subassembly with a conical friction surface having a sintered-on friction lining and cams, and is connected in a shape-locking manner by the cams to the clutch and interacts by means of the friction lining with the conical coupling surface.
