Abstract
A reverse sensor lubrication system in a toroidal type continuously variable transmission is disclosed. The transmission includes a forward/backward mode switching mechanism, a toroidal type power transmission unit powered by the switching mechanism, a power transmission shaft driven by an output cone disc of the power transmission unit, a transmission output shaft driven by the power transmission shaft through a gear unit interposed therebetween, a speed change control valve switching means which selectively actuates a forward movement speed change control valve and a backward movement speed change control valve, a reverse sensor which is mounted on the power transmission shaft to cause the switching means to actuate the backward movement speed change control valve when the power transmission shaft is rotated in a backward direction, and a hydraulic circuit which controls operation of the transmission. The reverse sensor lubrication system comprises a first block which, when the power transmission shaft is rotated in a forward direction, lubricates the reverse sensor by using a fluid splashed by the gear unit; and a second block which, when the power transmission shaft is rotated …
