Abstract: A torque converter, including: a cover for receiving torque; a pump non-rotatably connected to the cover; a turbine including a turbine shell; a turbine clutch including a portion of the turbine shell; a first torsional vibration damper including a first input plate non-rotatably connected to the turbine shell, a cover plate, an output flange arranged to non-rotatably connect to an input shaft for a transmission, and a plurality of springs, each spring in the plurality of springs engaged with the first input plate, the cover plate, or the output flange; a second torsional vibration damper including a second input plate, an output plate arranged to non-rotatably connect to the input shaft, and a spring engaged with the second input plate and the output plate; and a lock-up clutch including an axially displaceable piston plate arranged to non-rotatably connect the cover and the second input plate.

Abstract: A clutch plate for a torque converter is provided. The clutch plate includes a core plate and a friction material layer fixed to the core plate. The friction material layer includes an inner radial portion of a first thickness and an outer radial portion of a second thickness less than the first thickness. The friction material layer includes radially extending channels defined therein extending from an inner circumference of the inner radial portion to the outer radial portion. A method for forming a clutch plate is also provided.

Abstract: A rocker one-way clutch includes a stator housing, an inner race, and a strut. The stator housing has a strut pocket and a plurality of stator blades. The inner race has a first angled contact face. The strut is disposed in the strut pocket and has a second angled contact face arranged to contact the first angled contact face. In an example embodiment, an angle between a line passing from the contact face to a rocker pivot center and a line parallel to the contact face is acute. In an example embodiment, the acute angle is approximately 10 degrees.

Abstract: A vibration damper, including a cover plate with an annular portion, and a spring portion including spring retaining portions forming respective spaces and a spring blocking portions including respective protrusion segments and respective tab segments including respective portions of an edge of the cover plate and having a same first thickness. The damper includes springs at least partially located in the respective spaces, and having respective longitudinal ends, and a second cover plate or output flange connected to the cover plate. The springs are arranged to transmit torque to the cover plate. The respective protrusion segments have a same second thickness and include respective protrusions. Respective first portions of the longitudinal ends of the springs are engaged with the respective protrusions. Respective second portions of the longitudinal ends of the springs are engaged with the respective tab segments.

Abstract: The invention presented is an outer race for a stator assembly which includes keys that extend radially outward from the outer circumferential edge. The keys include transverse projecting splines. The splines are configured to cut grooves into the body of a stator to form a press fit connection between the outer race and the stator. The connection reduces or eliminates a loosening of the stator-outer race connection when fluid temperatures increase as well as reducing the effects of lash by reducing or eliminating gaps in the stator-outer race connection.
