Abstract
A drive clutch having a compressible torque transfer mechanism configured to transfer torque from an engine or motor to a moveable sheave and configured to reduce wear on components of the drive clutch by eliminating sliding contact between surfaces to transfer torque and change the gear ratio. The torque transfer mechanism increases efficiency and reduces wear and may comprise a torque bellows, which is configured to transfer torque from the engine to the moveable sheave upon radial compression of the torque bellows. Sliding blocks and corresponding slide tracks are concentrically positioned between the moveable sheave and the shift plate and centrifugal force provides a force for linear movement for the sliding blocks, which results in movement of the moveable sheave and the cover, which can act to compress the torque bellows. This configuration reduces costs because precise machining is not needed and reduces premature wear and tear on the drive clutch.
