FIELD: machine building.
SUBSTANCE: invention relates to a continuously variable transmission drive pulley. Drive pulley has a fixed sheave, a fixed sheave shaft fixedly connected to the fixed sheave, a movable sheave, a movable sheave shaft fixedly connected to the movable sheave, a spider and one centrifugal actuator. Fixed sheave shaft is disposed inside the movable sheave shaft. Movable sheave is disposed axially between the spider and the fixed sheave. Biasing member biases the movable sheave axially away from the fixed sheave. Torque transfer assembly is operatively connected to at least one of the fixed sheave and the movable sheave. Torque transfer assembly transfers torque between the fixed sheave and the movable sheave. Biasing member, one centrifugal actuator and torque transfer assembly are disposed radially outward of the fixed and movable sheave shafts.
EFFECT: higher device reliability.
