摘要： A power transmission unit for a vehicle is provided. In the power transmission unit, torque is transmitted between an input shaft and an output shaft through a continuously variable transmission and a gear train having an intermediate shaft. The continuously variable transmission adapted to alter a speed ratio continuously is disposed between the input shaft to which a torque of a prime mover is inputted and the output shaft that outputs the torque. The gear train is adapted to establish a speed ratio that cannot be established by the continuously variable transmission, and arranged at a different site from positions of the input shaft and the output shaft. The power transmission unit comprises: a torque reversing device that is adapted to perform a differential action among an input element, an output element and a reaction element adapted to rotate the input element and the output element in opposite directions when rotation thereof is halted, and that is disposed coaxially with the output shaft or the intermediate shaft; a first clutch device that connects at least any of two rotary elements of the torque reversing device; and a brake device that halts rotation of the reaction element. The input shaft is connected with the output shaft through the continuously variable transmission, and a second clutch device is disposed on a torque transmitting route from the input shaft to the output shaft via the continuously variable transmission to allow and interrupt torque transmission therethrough. The input shaft is connected with the output shaft through the gear train and the torque reversing device.

摘要： A power transmission system having a pendulum damper is provided. A rolling member of the pendulum damper is arrange in a rotary member, and a vibration damping performance of the pendulum damper is enhanced by increasing an inertia moment of the rolling member to be larger than that of the rotary member. The power transmission system is comprised of a hydraulic route for transmitting power between an input member and an output member through a fluid coupling, a mechanical route for transmitting power between the input member and the output member by engaging a lockup clutch, a pendulum damper that damps torsional vibrations of the output member by an oscillating motion caused by the torsional vibrations, and an elastic damper that damps the torsional vibrations by a relative rotation between a drive member and a driven member connected through an elastic member. The pendulum damper is disposed on the mechanical route, and one of the lockup clutch and the elastic damper is disposed on an output side of the pendulum damper.

In the power transmission unit, a continuously variable transmission to alter a speed ratio continuously is disposed between an input shaft to which a torque of a prime mover is inputted and an output shaft rotated by the torque transmitted from the input shaft.
