Abstract
A drive sheave assembly of a continuously variable transmission is provided that includes a post, a fixed sheave, a movable sheave assembly, a sleeve and an engine braking assembly. The engine braking assembly includes an axial activation member, a one-way engagement member and a flange. The axial activation member is statically mounted within a central recess of the fixed sheave. The axial activation member is movably connected with the one-way engagement member. A central passage of the one-way engagement member is configured to engage a portion of the sleeve. The flange is coupled to the one-way engagement member to selectively engage a side of an endlessly looped member with axial movement of the one-way engagement member during an engine braking condition.
