Abstract: Presented are torque converters (TC) with planetary-type vibration dampers, methods for making/using such TC assemblies, and vehicles equipped with such TC assemblies. A TC assembly includes a TC housing drivingly connected to a prime mover to receive torque therefrom, and a TC output member drivingly connected to a transmission to transfer torque thereto. Rotatably mounted within an internal fluid chamber of the TC housing are juxtaposed turbine and impeller blades. The impeller blades are rotatably mounted to the housing. A TC clutch is operable to lock the TC housing to the TC output member. A torsional vibration damper, which is disposed within the internal fluid chamber, includes a sun gear attached to the TC output member for unitary rotation, a ring gear attached to the TC clutch for unitary rotation, and a planet carrier intermeshed with the ring and sun gears and attached to the turbine blades for unitary rotation.

Abstract: A torque converter assembly includes a pump and a turbine fluidly connected together. A vehicle includes the assembly operable between an output shaft of an engine and an input member of a transmission. The assembly includes a damper and a clutch operable between the pump and the turbine. The damper is operable upstream from the clutch such that oscillation from the pump is reduced by the damper before oscillation reaches the clutch. The clutch includes first and second plates and a friction plate disposed between the first and second plates. The assembly includes a casing that contains the pump, the turbine, the damper and the clutch. A first part of the casing and the first plate define a first chamber. A first part of the turbine and the second plate define a second chamber. The clutch between the first and second plates defines a third chamber.

Abstract: A system for absorbing vibration and transmitting torque from a rotating power source to a rotatable load includes a rotatable driving member configured as an input to be driven by the power source to rotate about an axis of rotation. The system has a cam plate with a cam surface. A spring is configured to extend lengthwise in a radial direction relative to the axis of rotation. The spring is configured to be compressed due to the cam surface during relative rotation of the driving member and a driven member when the cam plate is operatively connected to rotate in unison with said one of the driving member and the driven member. The spring therefore has an effective spring rate dependent upon the cam surface, compression of the spring absorbs torsional vibration of the driving member, and the cam plate.

Abstract: An electrified multiple speed ratio transmission for mounting to an external power-source and transmitting a power-source torque therefrom includes an input member configured to receive the power-source torque. The transmission also includes a torque transfer system configured to receive the power-source torque from the input member and select an input-to-output speed ratio of the transmission. The transmission additionally includes an electric motor operatively connected to the torque transfer system and configured to apply an electric motor torque input thereto. Furthermore, the transmission also includes an output member operatively connected to the torque transfer system and configured to receive the power-source torque and the electric motor torque input therefrom and output a sum of the power-source torque and the electric motor torque input to drive a load. A vehicle having such an electrified multiple speed ratio transmission is also envisioned.
