Abstract
PURPOSE:To obtain running performance coping with drive requirements by making the slope of the engine speed of respective lines to car speed differ from each other in controlling a speed change ratio corresponding to respective speed change lines of each engine load so that a speed reduction ratio may be reduced according to the increase in car speed. CONSTITUTION:A continuously variable transmission 1 is provided with the drive clutch 20 arranged in the output side of the fluid coupling 10 connected to the output shaft A of an engine and a belt type transmission mechanism 40 transmitting the output of an advance and retract switch device 30 to the wheel side output shaft B. The belt type transmission mechanism 40 comprises a belt 45 belted around the respective pulleys 43 and 44 arranged to an input shaft 41 and output shaft 42. And the speed change ratio of the transmission mechanism 40 is controlled in accordance with each speed change line of the respective engine load set engine speed at a specified slope to car speed so that a speed reduction ratio may be reduced according to the increase in car speed. In this case, the slope of engine speed in each speed change line in relation to car speed is made to differ from each other.
