ABSTRACT:
A dual cone pin type synchronizing clutch for driveably connecting to a shaft gear wheels journalled on the shaft includes a hub splined to the shaft, a clutch sleeve connected to the hub through spline teeth that permit axial displacement of the sleeve into engagement with clutching teeth formed with the gear wheel. Each gear wheel carries a cone element engageable with a conical friction surface that is fixed to the gear wheels. A cone arm assembly carries cone members adapted to engage frictionally an intermediate cone member when the sleeve is displaced. The frictional contact between the cone elements, which engage before the clutching teeth engage, operate to synchronize the speed of the gear wheels to that of the synchronizer hub. The sleeve defines a space within which a detent spring is trapped and forced radially outward against the inner surface of the cone arm assembly, when the sleeve is displaced from the neutral position, or into a detent groove, when the clutch sleeve returns to the neutral position.
