Abstract
An infinitely variable traction roller transmission which has traction rollers pivotally supported between toric discs mounted opposite each other on coaxial input and output shafts. The traction rollers are rotatably supported on a support block which is laterally movably supported on a pivotal traction roller support structure. The traction roller support block and pivotal support structure have cooperating bearing surfaces with rollers arranged therebetween to permit lateral movement of the support block. The bearing surfaces or bearing rollers are so formed that the support block is lifted off the pivotal support structure upon torque-induced lateral movement of the traction rollers in order to engage the traction rollers with the toric discs.
