Abstract
A continuously variable transmission in which a circular driver, positioned between and frictionally engaged with op posing surfaces of two oppositely rotatable disks, which are urged towards each other with a biasing mechanism, is mounted to, and is movable axially along, a drive shaft which extends radially from an input shaft which rotates the drive shaft about a longitudinal axis of the input shaft, and wherein output drive is taken from the disks via a speed balancing system.
Claims12
A CVT variator which includes a first disk which is rotatable about a first axis in a first direction and which has a first disk face, a second disk, spaced from the first disk which is rotatable about the first axis in a second direction which is opposite to the first direction and which has a second disk face opposing the first face, a drive device which includes a driver with a circular rim and with a central axis, wherein the driver is mounted at a radial distance from the first axis between the first disk face and the second disk face for rotation about the central axis at a first rotational speed, a clamping mechanism for urging the disks towards each other so that the circular rim of the driver is frictionally engaged at a first contact location with the first disk face and at a second contact location with a second disk face whereby, upon rotation of the driver at the first rotational speed, the first disk and the second disk are respectively rotated and produce respective first and second rotational output drives, an actuator for varying said radial distance, and a coupling system which couples together the first and second output drives to produce a combined output drive at a second rotational speed.
