摘要
A strut-type synchronizer for coupling a gear to a rotating shaft includes a hub rotating with the shaft, a clutch ring rotatable with the gear, and a friction ring disposed between the hub and the clutch ring. The hub supports several struts for relative axial movement, as urged by an encircling splined sleeve through a detent, into engagement with the friction ring. The friction ring, which does not itself directly engage the sleeve, has a friction surface that is thus urged by the struts into engagement with a complementary friction surface of the clutch ring, whereupon relative rotation between the friction ring and the clutch ring ceases, the detent is overcome, and the sleeve's spline teeth engage complementary spline teeth on the clutch ring to fully engage the synchronizer. The friction surfaces include two axially-spaced frustoconical portions, by which an increased cone torque is achieved during synchronization.
