Abstract
A drive clutch for a continuously variable transmission that includes an input shaft designed to engage with an engine. A sheave assembly is mounted about the input shaft. A bearing assembly separates the sheave assembly from the input shaft such that the input shaft can rotate independently from the sheave assembly. At least one sheave clutch assembly is positioned about the input shaft. The sheave clutch assembly is configured to provide engagement between the sheave assembly and the input shaft when the rotation of the input shaft increases above a certain threshold value. An axial control mechanism is mounted on the input shaft adjacent to the second sheave. The axial control mechanism controls the movement of the second sheave toward and away from the first sheave as a function of the speed of the input shaft. A continuously variable transmission including the drive clutch and a driven clutch is also disclosed.
