Abstract: A torque converter having a pump, a turbine, and a lockup clutch assembly with a piston and a clutch plate. The lockup clutch assembly is capable of balancing pressure on opposing sides of the lockup clutch assembly to facilitate application of the lockup clutch assembly, in particular during an overrun condition in which the turbine rotates faster than the pump.

Abstract: A protective shield configured to protect an oil pan from impact. The oil pan is illustratively formed of a polymer, and the protective shield is illustratively formed of an elastomer. A coupler illustratively secures the protective shield to the oil pan.

Abstract: A torque-transfer assembly includes a fluid transfer tube located within a bore of a shaft. The fluid transfer tube seals to the shaft and includes at least one fluid groove that communicates between a plurality of fluid ports located in the shaft. The fluid groove is defined by an outer surface of the fluid transfer tube.

Abstract: The present invention provides an assembly for attaching a hub to a shaft. The hub, which may be a portion of a gear, pulley, chain sprocket or other power carrying device, includes a collar or annular wall having two axially extending relief cuts on opposite sides of a shaft opening, which define a pair of opposed projections or clamp members. The clamp members include opposed flats on the inside of the shaft opening which engage complementarily configured flats on the shaft. A threaded fastener such as a bolt extends through smooth radial bores in one clamp member and the shaft and into a complementarily threaded bore in the other clamp member. The internal flats of the hub include opposed arcuate, axially extending reliefs. The outside surface of the hub proximate the smooth bore defines a chordal surface which the bolt engages.
