<p>In an infinitely variable transmission wherein two toric traction discs (20, 22) are rotatably supported in a housing (10) opposite one another so as to define therebetween a toric cavity (24) in which at least two motion transmitting traction rollers (26, 28) are disposed in engagement with the toric discs (20, 22) and supported by pivot trunnions (30, 32), each pivot trunnion (30, 32) is provided with a single support roller (34, 36) disposed on a track section (54) and has an axial control end (56) which is supported so as to be slightly movable in a plane normal to the axis of the toric discs (20, 22) and means (62-70) are provided for controllably moving the trunnion control ends (56) in unison for initiation of a transmission ratio change.</p><p>In this manner ratio changes are initiated mechanically in a simple manner.</p> |
