PURPOSE:To enable a belt type no-stage speed change gear of being varied in speed change ratio through a wide range without any change in specifications thereof by providing an input torque dividing device at the preceedent stage of the speed change gear and also providing a torque combination device at the following stage thereof. CONSTITUTION:Output of an engine is transmitted to a ring gear 5 of an input torque dividing device A which consists of a planetary gear mechanism. The carrier 7 of the input torque dividing device and a sun gear 8 are joined with the driving pulley 9 of a belt-type non-stage speed change gear B and a torque combination device C, respectively. In said torque combination device, one of divided input torques and output of the driven pulley of the belt-type non- stage speed change gear are to be combined with each other. In accordance with speed change ratio of the planetary gear mechanism of the input torque dividing device, speed change ratio of the belt-type non-stage speed change gear may therefore be varied in a wider range with respect to speed change ratio of the pulley of the belt-type non-stage speed change gear. |
