Claims33
A vehicle, comprising:
- a plurality of ground-engaging members;
- a frame supported by the ground-engaging members;
- and
- a powertrain assembly supported by the frame and including:
- an engine;
- a continuously variable transmission operatively coupled to the engine, the continuously variable transmission including a drive clutch and a driven clutch, the drive clutch operatively coupled to the driven clutch, the drive clutch including:
- a stationary sheave operatively coupled to the engine;
- and
- a moveable sheave configured for movement relative to the stationary sheave, the moveable sheave including a tower member, an intermediate member positioned adjacent the tower member and having at least one post, a cover member positioned adjacent the intermediate member such that the intermediate member is intermediate the tower member and the cover member, and a position member radially movable relative to the intermediate member and the tower member, wherein the intermediate member includes at least a first post and a second post, and at least a portion of the position member is positioned intermediate the first and second posts.

A continuously variable transmission for coupling a drive shaft and a driven shaft, the continuously variable transmission comprising:
- a housing having an interior and having a first opening adapted to receive the drive shaft and a second opening adapted to receive the driven shaft;
- a driven clutch positioned within the interior of the housing and adapted to be operatively coupled to the driven shaft;
- and
- a drive clutch positioned within the interior of the housing and adapted to be operatively coupled to the drive shaft and the driven clutch, the drive clutch including a first drive clutch sheave and a second drive clutch sheave moveable relative to the first drive clutch sheave, the second drive clutch sheave including a tower member, an intermediate member positioned adjacent the tower member and having at least one post, and a cover member positioned adjacent the intermediate member such that the intermediate member is intermediate the tower member and the cover member, and a position member radially moveable relative to the intermediate member and the tower member, wherein the moveable sheave includes at least one weight positioned generally within the at least one post, and at least a portion of the position member is circumferentially aligned with the at least one weight.
