Abstract:
An indexing gear assembly (20, 30, 50a, 50b, 60a, 60b) for a synchronizing device for a geared speed change transmission installed in motor vehicles, comprising an indexing gear (21, 31, 41, 51, 61), a coupling body (22, 32, 52, 62) and a friction ring (23, 33, 53, 63), the coupling body (22, 32, 52, 62) having external gearing which is adapted to be joined form-locking with a sliding connector during a shifting operation, the friction ring (23, 33, 53, 63) includes a conical friction area (28, 38, 58a, 58b, 68a, 68b, 68c) which is adapted to interact with a synchronizing ring during synchronization, the indexing gear (21, 31, 51, 61), the coupling body (22, 32, 53, 63) and the friction ring (23, 33, 53, 63) being constructed as component parts which are prefabricated and are joined in a rotatably fixed manner with each other to create the indexing gear subassembly (20, 30, 50a, 50b, 60a, 60b).
