In the V belt type continuously variable transmission, after the output power from the prime mover has been transmitted to the input pulley shaft, two paths are operable to transmit the output power from the input pulley shaft to the output pulley shaft, two paths which are a main power transmitting path through a V belt engaged between the input pulley and the output pulley and a sub power transmitting path through the 2-way differential clutch. The drive ratio of the sub power transmitting path is set in a slightly smaller value than the maximum drive ratio of the main power transmitting path. When the movable input half pulley of the input pulley has been moved near the position of the maximum drive ratio in the main power transmitting path, the rotational speed of the output gear in the 2-way differential clutch become slower than that of the input gear, and as a result a rotational force is given to the output gear so that the output pulley shaft is rotated through the sub power transmitting path in addition to the main power transmitting path so that it becomes possible to increase driving power and accelerating force and also to decrease load to be added to the V belt.

Continuously variable transmission

A continuously variable transmission is provided with a driving pulley comprising a stationary half pulley fixed to a driving shaft and a movable half pulley, and a driven pulley comprising a stationary half pulley fixed to a driven shaft and a movable half pulley. A V-groove is formed between the stationary half pulley and the movable half pulley and adjustable by moving the movable half pulley in the axial direction in each of the driving pulley and the driven pulley. An endless belt is wrapped to each V-groove, and rotation of the driving shaft is transmitted to the driven shaft steplessly. A slider gear disposed in the axial direction is connected one or both half pulleys of the driving pulley, and is threadedly engaged with a slider shaft and driven by a driving source and moved forward or rearward in the axial direction on the slider shaft, so that one or both half pulleys are moved forward or rearward in the axial direction and the distance between both half pulleys is adjusted. A new combination of the control system and drive mechanism provides improved performance.
