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.

Claim (Index 16):
A torque converter assembly for transmitting torque from a crankshaft of an engine to an input shaft of a transmission, the torque converter assembly comprising:\n a pump portion configured to be driven by the crankshaft of the engine to rotate about an axis of rotation; a turbine portion configured drive the input shaft of the transmission and be driven by the pump portion via a fluid coupling to rotate about the axis of rotation and transmit torque from the engine to the transmission; a cam plate operatively connected to the pump portion to rotate in unison therewith, the cam plate having an inner periphery with a plurality of circumferentially spaced cam surfaces separated from each other by a plurality of shoulders, each of the shoulders having a rectilinear wall adjoining a respective one of the cam surfaces; and a plurality of springs connected to the turbine portion to rotate in unison therewith about the axis of rotation, each of the springs extending radially relative to the axis of rotation into operative engagement with a respective one of the cam surfaces such that the spring is compressed by the cam surface during relative rotation between the crankshaft and input shaft whereby the springs cooperatively absorb torsional vibrations generated by the engine, wherein each of the springs is configured to engage a respective one of the rectilinear walls when rotating in a first direction whereby the shoulders restrict rotation of the springs relative to the cam plate.
