Abstract:
1. An input torque system for a continuously variable transmission having a longitudinal axis, the input torque system comprising: an input shaft having a splined flange; a torsion disc having a splined bore; wherein the splined flange and splined bore are adapted to couple together operationally to transmit torque from the input shaft to the torsion disc; and a first load cam disc coupled to the torsion disc; a plurality of rollers coupled to the first load cam disc; a second load cam disc coupled to the plurality of rollers; wherein the plurality of rollers is positioned axially between the first load cam disc and the second load cam disc; an input disc coupled to the second load cam disc, the input disc having a plurality of lubrication ports arranged on an outer periphery of the input disc; and a plurality of balls arranged angularly about the longitudinal axis, each ball in contact with the input disc, each ball having a tiltable axis of rotation.
