Abstract: A torsional vibration damper includes a planetary gear set connected to a transmission input shaft, including a sun gear, a carrier, and a ring gear. A spring cage includes a first spring support member connected to the ring gear having multiple first spring contact members. A second spring support member is connected to the carrier and rotates with respect to the first spring support member. The second spring support member has multiple second spring contact members angularly oriented with respect to the first spring contact members. Multiple springs having opposed ends are positioned between and are compressed by rotation of the first or the second spring support member. The springs compress and extend to absorb vehicle engine vibration pulses. Each end of the springs has one of the multiple first spring contact members and or one of the multiple second spring contact members positioned proximate thereto.

Abstract: An electric motor damping module includes an electric motor, a motor damper continuously interconnected with the electric motor, and an input member continuously interconnected with the motor damper. A transmission includes these elements, plus an output member, first, second, and third planetary gear sets each having first, second and third members, a first interconnecting member continuously interconnecting the third member of the first planetary gear set with the second member of the second planetary gear set, a second interconnecting member continuously interconnecting the second member of the first planetary gear set and the output member with the third member of the third planetary gear set, and a third interconnecting member continuously interconnecting the third member of the second planetary gear set with the second member of the third planetary gear set. The transmission also includes six torque transmitting mechanisms and a hydraulic pump. A sealing assembly is also provided.

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.
