Abstract

A vehicle is described having a transmission driven through a propulsion unit such as an engine, and through a CVT. The transmission is comprised of an input shaft and an output shaft which are coaxially disposed. An idler shaft is driven by the input shaft, and the idler shaft drives the output shaft, through selected gear sets, to provide different gear ratios or drive directions. The CVT also has a fan on the driven side which feeds air through the CVT for cooling. The CVT comprises a drive side clutch and a driven side clutch with the output shaft of the extending through the CVT driven clutch.
