Abstract

A continuously variable transmission wherein each of two parallel shafts carries a pulley having a fixed flange and a second flange movable axially of the shaft toward and away from the respective fixed flange. An endless torque transmitting chain or belt is trained over the two pulleys. At least one flange of at least one of the pulleys is assembled of two or more parts which consist of sheet metal and are welded and/or otherwise affixed to each other.
