Various configurations of a continuously variable transmission include a drive pulley, a driven pulley and a belt extending therebetween. The drive pulley is generally comprised of a moveable sheave half and a fixed sheave half. The moveable sheave half is freely rotatable relative to the drive shaft and the fixed sheave half. Torque is transferred between the moveable sheave half and the stationary sheave half through the use of a roller bearing and channel race arrangement; however, the roller bearings are freely translatable within the channel races. The continuously variable transmission also features a differential positioned between the two output pulleys and an articulating member positioned between the two input pulleys. These two members operate together to eliminate bucking of the belts caused by differences in driven speeds of the two driven pulleys in a parallel configuration of the variable speed transmission. Additionally, a method of assembling the transmission is also described.
