Continuously variable transmission

A continuously variable transmission for coupling a drive shaft and a driven shaft, the continuously variable transmission comprising:

• a housing including a base having a first opening adapted to receive the drive shaft and a second opening adapted to receive the driven shaft and a cover being coupled to the base, the cover and the base cooperating to define an interior of the housing;
• a drive clutch positioned within the interior of the housing and adapted to be operatively coupled to the drive shaft, the drive clutch including a first drive clutch sheave and a second drive clutch sheave moveable relative to the first drive clutch sheave;
• a driven clutch positioned within the interior of the housing and adapted to be operatively coupled to the driven shaft, the driven clutch being operatively coupled to the drive clutch and including a first driven clutch sheave and a second driven clutch sheave moveable relative to the first driven clutch sheave;
• a first number of air supply conduits coupled to the housing, each providing non-recycled air from an exterior of the housing to the interior of the housing through at least one air supply openings in the housing;
• and
• at least one air outlet conduit coupled to the housing,
• wherein a second number of the first drive clutch sheave, the second drive clutch sheave, the first driven clutch sheave, and the second driven clutch sheave are directly contacted by the non-recycled air provided by the first number of air supply conduits, and
• the second number being greater than the first number and the second number is equal to four.
