摘要： PROBLEM TO BE SOLVED: To achieve fail-safe by a simple structure in a full-toroidal continuously variable transmission.
SOLUTION: The abnormality of pressure in the oil chambers 23, 24 of a hydraulic cylinder 20, providing push-pull force to a roller 17 is monitored by first and second pressure sensors 32, 37. For example, when the abnormality of pressure in the first oil chamber 23 is detected, a pressure command value P2d to a second pressure control valve 34, corresponding to the second oil chamber 24, is corrected on the basis of the difference ΔP between the detected values of both sensors 32, 37 (equal to the difference between the detected pressures of both oil chambers 23, 24). Namely, by controlling the second pressure control valve 34 in the hydraulic pressure supply line to the second oil chamber 24, functioning normally, the difference in the pressure between both the oil chambers 23, 24 is prevented from becoming abnormal. The variable transmission functions normally in the overall system.
