ABSTRACT:
An infinitely variable traction roller transmission with preferably four traction rollers arranged between, and in engagement with, opposite toric discs for the transmission of motion therebetween includes, for each roller, a pivotal support member having a roller supported thereon by a hydrostatic or an antifriction bearing including hydraulic fluid adapted to force the roller into motion transmitting engagement with the toric discs. The pivotal support member is supported by antifriction bearing segments or hydrostatic means and has gear segments disposed at opposite ends thereof, with the gear segments of adjacent roller support members being in meshing engagement for transmission ratio changing pivot movement of all the traction rollers in unison.
