Abstract:
1. An oil supply system for a transmission comprising: a transmission casing; an output shaft disposed in the transmission casing; a plurality of gears relatively rotatably fitted on the output shaft; an oil passage axially formed in the output shaft, wherein the oil passage is opened at outer peripheral portions of the output shaft adjacent to the gears, and opened at one axial end of the output shaft; a trough portion formed on an inside wall of the transmission casing so as to receive oil splashed from the gears, wherein the trough portion is disposed above the output shaft and extended axially along the output shaft; a connection passage formed in a side wall of the transmission casing and extending downwardly from the trough portion to the oil passage; an automatic continuously variable belt transmission disposed outside the transmission casing, and wherein the plurality of gears includes a normal gear and a reverse gear, wherein the normal gear and the reverse gear are drivingly interposed between the belt transmission and the output shaft so that either the normal gear or the reverse gear is selectively fixed to the output shaft so as to determine one of opposite rotary directions of the output shaft.
