The present invention broadly comprises a torque transfer apparatus for a torque converter including at least one connection element attached to an inner circumferential surface for a cover of the converter; a lock-up clutch, and at least one resilient element connected to the connection element and the piston plate. The clutch includes a piston plate with extruded rivets and the resilient element is connected to the piston plate with the extruded rivets. In some aspects, the clutch includes a friction material having inner and outer radii and the extruded rivets are disposed at a radial distance greater than the inner radius; the extruded rivets are disposed between the inner and outer radii; a radial segment for the connection element extends radially from the inner surface and has an edge at a greater radial distance than the inner radius; or the resilient element is between the inner and outer radii.

Clutch attached to an outer rim of a torque converter

A torque converter in which a plurality of output openings of the pump form a cone-shape so that a plurality of input openings of the turbine are substantially parallel to the plurality of output openings of the pump.
