Document Type and Number:
Japanese Patent JP2003536032
Kind Code:
A
Abstract:
The invention comprises a geared drive ring coupler. The geared drive ring coupler comprises two pairs of adjacent drive rings rotatably connected to each end of a frame. Each pair of drive rings is meshed together with the cooperating pair of drive rings on the opposing end of the frame. The relative spatial arrangement of the axis of rotation of each set of drive rings is maintained by the frame, which in turn holds the drive rings in a predetermined relationship between the pulley sheaves. The drive rings on the driver pulley turn in the same direction as the driver pulley through frictional contact with the sides of the CVT driver pulley sheaves. The drive rings on the driven pulley side rotate in the opposite direction to the drive rings on the driver pulley, since they are meshed together. The driven drive rings are then in frictional contact with the sides of the driven pulley sheaves, thereby driving the driven pulley. The effective diameter or radius of each pulley is adjusted by movement of the pulley sheaves. Movement of the pulley sheaves causes the axis of rotation of each set of drive rings to move eccentrically with respect to the axis of rotation of their respective pulley. Since the drive rings are mechanically connected, the drive rings move with the frame as a unit in response to the movement of the pulley sheaves, thereby changing the effective gear ratio of the transmission.
