Abstract: A powertrain system including an internal combustion engine rotatably coupled to a variator of a continuously variable transmission (CVT) is described. A method for controlling the CVT includes determining a first speed ratio change rate based upon a desired speed ratio and a commanded speed ratio, and determining a commanded speed ratio trajectory based upon the first speed ratio change rate, an actual speed ratio and a commanded speed ratio. A ratio change coefficient and a force ratio factor are determined based upon the commanded speed ratio trajectory. A shift force is determined based upon the ratio change coefficient and a total speed ratio change rate. A primary pulley pressure and a secondary pulley pressure for the CVT are controlled based upon the shift force and the force ratio factor.

Abstract: A system for absorbing vibration in a rotary member having a predetermined rotary speed of the present invention has a selectively moveable mass and a positioning mechanism. The mass is in communication with the rotary member having a predetermined position. The positioning mechanism exerts a force on the mass at least when the rotary member operates below the predetermined rotary speed. The force exerted by the positioning mechanism orients the mass at the predetermined position when the rotary member operates below the predetermined rotary speed.

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: 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.
