<P>PROBLEM TO BE SOLVED: To reduce the minimum shifting ratio of a power transmission device while highly keeping the transmission efficiency of driving force in a stepless transmission. <P>SOLUTION: The fuel consumption ratio of an engine can be reduced by reducing the total transmission ratio of the stepless transmission T and the power transmission device including an acceleration mechanism 34 while keeping the relatively high transmission efficiency by making the transmission ratio of the stepless transmission T a relatively large value because the power transmission device has an acceleration mechanism 34 accelerating and transmitting the rotation of an output shaft 12 of the stepless transmission T to driving wheel transmission shafts 36, 37. Friction can be reduced by setting friction dampers of the one-way clutches weak by such a degree that a required response frequency of the one-way clutches of the stepless transmission T can be reduced the fluctuation of torque of the output shaft 12 generated by the plurality of one-way clutches operating in order can be reduced by the acceleration mechanism 34 and transmitted to the driving wheel transmission shaft 36, 37. <P>COPYRIGHT: (C)2013,JPO&INPIT |
