ABSTRACT:
A single drive ring CVT coupler. Opposing inclined planar sides on outer circumferences of the drive ring have a high friction coefficient for enhanced engagement and power transmission between the pulleys and the drive ring. The drive ring rotationally operates between the cooperating pulleys of a moveable sheave CVT transmission. The opposing sides are inclined at an angle to each other for proper fit between the sheaves of the driver pulley and driven pulley. The drive ring operates between the outboard portions of each pulley. In an alternate embodiment, a drive ring operates in a bearing and is retained between the driver and driven pulleys by a retainer that spans between the pulley shafts. The drive ring comprises inclined opposing frictional sides on outer circumferences for frictionally engaging the sheave sides of a driver pulley and driven pulley. The drive ring operates between the inboard portions of the driver and driven pulleys.
