Abstract
An output assembly for driving a drive pulley of a continuously variable transmission and for supplying hydraulic fluid thereto is disclosed. The output assembly has a shaft configured to connect to a motor output shaft and to the drive pulley; a cover surrounding a portion of the shaft; a bearing rotationally supporting the shaft in the cover; and a sleeve and two shaft seals disposed between the cover and the shaft. In operation: hydraulic fluid flows from a cover inlet passage to a first high pressure chamber defined between the cover and the sleeve, through a sleeve passage from the first high pressure chamber to a second high pressure chamber defined between the sleeve and the shaft, and from the second high pressure chamber to the drive pulley via a shaft passage and to a cover outlet passage via a low pressure chamber defined between the cover and the shaft.
