A method of constructing a torque transmission assembly is also provided. The method includes providing a first cover plate and a second cover plate supporting a radially inner set of springs therebetween; providing a first radially outer set of springs and a second radially outer set of springs in series with the first radially outer set of springs; and arranging the first radially outer set of springs for transferring torque from the second radially outer set of springs to the radially inner set of springs via the second cover plate.

A torque converter may include: an impeller and a turbine hub to form a chamber together, a damper piston connected to a damper clutch and divide the chamber into a damper chamber and a balance chamber, a discharge path to connect and block the balance chamber and control an internal flow rate of the torque converter, and an O-ring to open or close the discharge path.

A torque converter for a vehicle includes an impeller, a turbine, a stator positioned between the impeller and the turbine, a one-way clutch coupled to the stator and configured to couple to a fixed member, and a controllable clutch assembly. The controllable clutch assembly is configured to selectively engage the stator and the turbine such that the stator is able to rotate with the turbine to facilitate preventing the stator from reacting against the one-way clutch and applying a load to the fixed member and thereby facilitating reducing an output of the torque converter and reducing engine vibration during idle, and disengage the stator from the turbine to enable relative rotation between the stator and turbine.

A hybrid module for a vehicle includes a torque converter and an electric motor. The torque converter includes an impeller shell and a cover. The cover is fixed to the impeller shell to form at least a portion of an outer shell for the torque converter. The electric motor includes a rotor supported on a rotor carrier. The cover and the rotor carrier are integrally formed from a same piece of material. In an example embodiment, the hybrid module includes a resolver rotor fixed to the rotor carrier. In some example embodiments, the hybrid module includes a cover disk, fixed to the rotor carrier and extending radially inward to form a portion of the outer shell.

A method of manufacturing a case for a starting device, the case having at least one curved portion and having an interior configured to be supplied with oil includes forming a thickened portion by partially thickening a metal sheet material and forming the curved portion by bending the sheet material at the thickened portion by press working. An outer surface of the curved portion projects outward of the case beyond a curved surface that is concentric with an inner surface of the curved portion and that has a radius of curvature equal to the sum of the radius of curvature of the inner surface and the thickness of the sheet material forming the case. Metal flows in the curved portion are continuous from the inner surface to the outer surface without any break.

A lock-up device for a torque converter is disclosed. The lock-up device includes a clutch part, first and second rotary members, a plurality of elastic members and a stopper mechanism. The clutch part is provided between a front cover and a turbine, and transmits the torque inputted to the front cover to the turbine. The first rotary member is disposed between the clutch part and the turbine. The second rotary member is rotatable relative to the first rotary member. The elastic members elastically couple an outer peripheral part of the first rotary member and an outer peripheral part of the second rotary member in a rotational direction. The stopper mechanism is disposed axially between the elastic members and an outer peripheral part of a turbine shell. The stopper mechanism includes an engaging portion restricting an angular range of relative rotation between the first rotary member and the second rotary member.
