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.

Abstract: A powertrain for a vehicle includes an engine, a continuously variable transmission (CVT) operatively connected to the engine, a transmission operatively connected to the CVT, and a driving shaft operatively connected to the transmission. The driving shaft is positioned laterally between the engine and the CVT, and vertically higher than a lowest point of the engine. Additionally, a powertrain for a vehicle includes an engine having engine housing, a CVT having a CVT housing having first and second housing portions, the first housing portion being disposed between the engine housing and the second housing portion, a transmission having a transmission housing, and a driving shaft. The first housing portion is connected to the engine and transmission housing, the first housing portion has a supporting portion supporting the driving shaft, and a mounting bracket for mounting the powertrain to the vehicle. A transmission is also disclosed.

Abstract: A supercharger assembly has a supercharger housing defining an air inlet and an air outlet; an impeller disposed in the supercharger housing; an impeller shaft connected to the impeller for driving the impeller; a driveshaft connected to the impeller shaft for driving the impeller shaft, the driveshaft defining an oil supply passage; and a torsional damper connected to the driveshaft for driving the driveshaft. The torsional damper is configured for being operatively connected to a crankshaft of an internal combustion engine. The oil supply passage is positioned to supply oil to the torsional damper for lubricating the torsional damper.
