ABSTRACT:
An infinitely variable traction roller transmission has traction rollers arranged between toric discs which are forced toward each other for engagement with the traction rollers for the transmission of power. The traction rollers are mounted on pivotal support structures which are supported on tension sheets extending, and balancing the forces effective, therebetween. The tension sheets are held in position by guide blocks extending from the housing into openings in the tension sheets and permitting tilting of the tension sheet to permit axial movement of the roller support structures in opposite directions for initiation of a change of the transmission ratio.
