ABSTRACT:
A compact device for synchronizing the rotational speed of a gear with a shaft in a transmission. The device comprises a friction clutch including first and second cone clutch members, a positive clutch including first and second jaw clutch members, a plurality of springs reacting between the second members for biasing the second cone member toward engagement with the first cone member, a stop means for preventing engagement of the second cone with the first cone member until initial sliding movement of the first jaw member, and a blocker means for preventing engagement of the positive clutch until the friction clutch brings the gear to substantial synchronism with the shaft. The second jaw member includes an outer circumferential surface which supports an inner circumferential surface of the second cone member. The blocker means, which are defined on the outer and inner circumferential surfaces, allow limited relative rotation of the second cone clutch member on the second jaw member and prevent sliding movement of the second jaw member into engagement with the first jaw member until substantial synchronism is reached. Initial movement of the second jaw member engages the friction clutch through the springs; thereafter, force for engaging the friction clutch is transmitted through the blocker.
