ABSTRACT:
A friction shoe assembly for a speed-responsive clutch adapted for use in a hydrodynamic device to couple turbine and impeller members including a disc secured to the turbine member having a series of cam surfaces thereon formed in apertures in the discs. The friction shoe assemblies are mounted in the apertures in engagement with the cam surfaces. The friction shoe assemblies engage with the impeller at a predetermined speed of rotation of the turbine member, and the cam means induces a wedging engagement of the shoes with the impeller member. The shoe assemblies include a spring mounted roller secured thereto to provide a torque limit for the clutch and include a streamlined shoe body manufactured of sheet metal providing a streamlined configuration toward the oncoming oil stream.
