摘要：An infinitely variable traction roller transmission with preferably four tractionrollers (26, 28, 30, 32) arranged between, and in engagement with, opposite toric discs (20,22) for the transmission of motion therebetween includes, for each roller (26, 28, 30, 32) a
pivotal support member (34) having a roller supported thereon by a hydrostatic or anantifriction bearing (42) including hydraulic means adapted to force the roller (30) intomotion transmitting engagement with the toric discs (20, 22). The pivotal supportmember (34) is supported by antifriction bearing segments (38) or by hydrostatic meansand has gear segments (74) disposed at opposite ends thereof, with the gear segments(74) of adjacent roller support members (34) being in meshing engagement fortransmission ratio changing pivot movement of all the traction rollers (26, 28, 30, 32) inunison.
