ABSTRACT:
A continuously variable transmission having first and second rotating conical members; oriented to have parallel longitudinal axis with the smaller diameter end of one adjacent the larger diameter end of the other; a plurality of longitudinal channels disposed in the surface of each conical member; a first device encircling both of the first and second members; a second device disposed in each of the plurality of channels adjacent the first device capable of gripping the first device to transmit rotation of one of the first and second members to the other of the first and second members; a third device disposed adjacent both of the first and second members to control the time when each device grips to effect transmission of the rotation; fourth means coupled to one of the first and second members acting as a drive member to change the longitudinal location of the second device in the plurality of channels of the drive member; and fifth means coupled to the other of the first and second members acting as a driven member and to the second device of the drive and driven members to change the longitudinal location of the second device in the plurality of channels of the driven member to an appropriate longitudinal position relative to the longitudinal position of the first device on the drive member.
