Abstract

A synchronizer clutch assembly for a transmission comprising a synchronizer hub carried by a torque delivery shaft and including a cone clutch member carried by a gear forming a part of the transmission gearing and a synchronizer blocking ring. A C-shaped spring member is positioned in the inner circumference of the rim portion of the clutch hub and has a plurality of lugs which extend through openings in the hub. The shiftable clutch sleeve has ramped ridges engageable with the lugs on the spring member and compress the lugs radially inwardly. The blocker ring cone clutch frictionally engages the cone clutch of the gear upon movement of the clutch sleeve toward an engagement position until the rotary motion of the gear is brought into synchronism with the rotary motion of the shaft.
