Driven Clutch System
First Claim
1. A secondary driven clutch system for a continuously variable transmission, the secondary driven clutch system coupled to a shaft that is rotatable about a longitudinal axis, comprising:
- a stationary sheave coupled adjacent the shaft;
a movable sheave comprising a slot, and coupled adjacent the shaft, the movable sheave being movable closer to, or further from, said stationary sheave along the longitudinal axis;
a positional motor coupled to the moveable sheave at least in part via said slot, and configured to cause said moveable sheave to move closer or further from the stationary sheave;
wherein said slot is generally at an angle from said longitudinal axis and configured to reduce the longitudinal force needed to move said moveable sheave relative to said stationary sheave, as compared to a slot generally parallel to said longitudinal axis.

Abstract
This disclosure generally includes description of a secondary driven clutch system for a continuously variable transmission. The secondary driven clutch system may be coupled adjacent a shaft that is rotatable about a longitudinal axis. The system may include a movable sheave including a slot, where the movable sheave may be movable closer to or further from a stationary sheave along the longitudinal axis. The slot may be generally at an angle from the longitudinal axis and configured to reduce the longitudinal force needed to move the moveable sheave along the shaft along the longitudinal axis, as compared to a slot generally parallel to the longitudinal axis.

10. A vehicle comprising a continuously variable transmission system wherein the continuously variable transmission system comprises:
-
a secondary driven clutch system for the continuously variable transmission, the secondary driven clutch system coupled adjacent a shaft that is rotatable about a longitudinal axis, comprising; a stationary sheave coupled adjacent the shaft; a movable sheave positioned about the shaft, the movable sheave being movable closer to or further from the stationary sheave along the longitudinal axis; a motor coupled to the moveable sheave via a slot and configured to cause said moveable sheave closer or further from the stationary sheave; wherein said slot is generally at an angle from said longitudinal axis and configured to reduce the longitudinal force needed to move said moveable sheave relative to said stationary sheave, with respect to a moveable sheave with a slot generally parallel to said longitudinal axis. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
