Abstract: The invention provides apparatus for cooling at least one sheave and/or an endless belt of a continuously variable transmission (CVT). As previously mentioned, the CVT is comprised of a drive clutch, a driven clutch, and the endless belt disposed about the drive and driven clutches. Both the drive and driven clutches include an axially stationary sheave and an axially movable sheave. Certain embodiments provide a ventilation air path through at least one sheave of at least one clutch of the CVT. In addition, certain embodiments provide a ventilation air path through both sheaves of at least one clutch of the CVT. Further, certain embodiments provide apparatus adapted to direct air proximate to an outer face of at least one sheave of at least one clutch inward to a central area of the at least one sheave when the at least one sheave is rotated in a direction of rotation.
