Abstract

A continuously variable transmission assembly includes a driving pulley rotatable about a driving pulley axis and a driven pulley rotatable about a driven pulley axis. An endless belt operatively connecting the pulleys defines a belt reference plane, the driving and driven pulley axes passing therethrough. A housing encloses a space, the driving pulley, the driven pulley, and the belt being disposed at least in part therein. A driven pulley inlet and outlet defined in the housing are disposed closer to the driven pulley than the driving pulley. The driven pulley inlet, disposed on a first side of the belt reference plane, is configured to direct air from outside the housing into the space toward the driven pulley. The driven pulley outlet is disposed on a second side of the belt reference plane. Air flows from the space to the outside of the housing via the driven pulley outlet.
