ABSTRACT:
An infinitely variable traction roller transmission having a housing, input and output shafts rotatably and coaxially journaled to the housing, input and output toric discs mounted on the input and output shafts and rotatable together while being firmly engaged with the shafts, the opposed surfaces of the toric discs cooperating with each other to form a toroidal cavity, a plurality of traction rollers disposed in the toroidal cavity symmetrically with the axis of the input and output shafts, a trunnion device rotatably supporting the traction rollers and pivotably supporting the vicinity of a pivot axis perpendicular to the rotational axis thereof, and forcing means for firmer engaging the input and output toric discs with the traction rollers and generating a traction force, is provided with a support device for mounting the trunnion device on the housing for slight movement in the direction of the pivot axis, a displacing device provided at the end of the pivot axis of the trunnion device to displace the trunnion device in the axial direction, and a spring device cooperating with the displacing device in accordance with the amount of displacement of the displacing device resulting from said rotational movement.
