Claim 18:
19. A vehicle comprising:
an engine to generate engine torque:
a drivetrain configured to deliver the engine torque to wheels of the vehicle; and
a continuously variable transmission (CVT) coupling the engine torque between the engine and the drive train, the CVT including a drive sheave in operational communication with the engine and driven sheave in operational communication with the drivetrain, the drive sheave in operational communication with the drive sheave with an endless looped member, the drive sheave including,
a post;
a fixed sheave statically mounted on the fixed post, the fixed sheave including a central recess;
a movable sheave assembly slidably mounted on the post, the movable sheave assembly including a movable sheave activation assembly to axially move the movable sheave assembly on the post;
a sleeve rotatably mounted on the post, at least a portion of the sleeve positioned between the fixed sheave and the movable sheave assembly; and
an engine braking assembly including,
an axial activation member statically mounted within the central recess of the fixed sheave, the axial activation member having an inner surface that defines a central passage of the axial activation member, the inner surface of the axial activation member including one of a plurality of engaging grooves and a plurality of extending guides;
a one-way engagement member including an inner surface that defines a central passage of the one-way engagement member, the central passage of the one-way engagement member configured to engage a portion of the sleeve, the one-way engagement member including an outer surface, a portion of the outer surface of the one-way engagement member including one of a plurality of engaging grooves and a plurality of extending guides configured to engage the one of the plurality of engaging grooves and the plurality of extending guides of axial activation member to create a moveable connection, wherein the one-way engagement member is configured to rotate freely on the sleeve when the sleeve rotates in a first direction and lock onto the rotation of the sleeve when the sleeve rotates in a second direction causing the moveable connection between the one-way engagement member and the axial member to move the one-way member axially; and
a flange coupled to the one-way engagement member to selectively engage a side of the endless looped member with axial movement of the one-way engagement member.
