PCT No. PCT/GB90/01868 Sec. 371 Date May 28, 1992 Sec. 102(e) Date May 28, 1992 PCT Filed Nov. 30, 1990 PCT Pub. No. WO91/08405 PCT Pub. Date Jun. 13, 1991.A variator for a transmission of the toroidal-race rolling-traction type in which a multiplicity of input discs (1-4) and output discs (11-13) are arranged in coaxial sequence, all disc except the first (1) and last (4) in the sequence being formed with races (9, 10) on both of their faces. Drive is transmitted from the output discs to one (35) or several (45-47) output shafts, the output shaft or shafts preferably lying parallel to but displaced from the common axis (8) of the discs. Alternative ways of inter-relating the orientation of the torque-transmitting rollers (20), to produce single or multiple outputs of the transmission, are described. The invention offers the prospect of a variator of higher-than-normal traction-transmitting capacity but using discs of only normal size.
