Synchronizer clutch assembly for multiple ratio gearing

A synchronizer clutch assembly for a manual transmission comprising torque transfer gears, a torque delivery shaft, at least one of said gears being journalled for rotation about the axis of said shaft;

• said clutch assembly comprising a clutch hub secured to said shaft, a clutch sleeve secured to said hub and adapted for axial shifting movement relative to said hub;
• a blocker ring between said one gear and said hub, clutch teeth on said sleeve and on said one gear, blocker ring gear teeth between said sleeve clutch teeth and gear clutch teeth, said blocker ring and said one gear having engageable friction clutch surfaces;
• and
• a spring member having at least one spring element which cooperates with said blocker ring including a flexible portion adapted to engage said sleeve teeth as said sleeve is moved toward said blocker ring gear teeth whereby a friction clutch surface engaging force is developed on said blocker ring upon radial deflection of said spring element;
• said spring member having a radially disposed portion located between said blocker ring and said hub, said radially disposed portion being adapted to transfer said friction clutch engaging force to said blocker ring;
• said spring element having an end portion defining a spring retaining clip that engages said blocker ring, thereby holding said spring axially fast when it is assembled on said blocker ring.
