Inertia lock type synchronous clutch mechanism

摘要

An inertia lock type synchronous clutch mechanism wherein a shifting sleeve is splined to a clutch hub and has circumferentially spaced cam portions on each axial side for engaging axially convex portions of an elastic ring on each side which convex portions fit within circumferentially spaced notches formed in the rim of the clutch. The convex portions of the elastic ring engage a blocking ring to cause frictional engagement with the selected gear and synchronize the rotation of that gear and the clutch hub for smooth engagement between the shifting sleeve and that gear.
