DRIVING PULLEY OF CONTINUOUSLY VARIABLE TRANSMISSION Russian patent published in 2020 - IPC B62M9/08 

FIELD: machine building.

SUBSTANCE: group of inventions relates to driving pulleys. Drive pulley comprises fixed and movable disks. Pulley, as per the first version, comprises interval measured between first surface of disc and second surface of disc, at that interval varies around axis of rotation. In compliance with the second version, the pulley comprises an angle between the axis of rotation and at least one of the first surface of the disc and the second surface of the disc, which varies around the axis of rotation. Vehicle comprises frame, engine, drive shaft, stepless transmission. Infinitely variable transmission comprises drive pulley. In compliance with first version, drive pulley is oriented at angle to drive shaft, so that part of drive belt is in contact with drive pulley at maximum interval between discs when engine experiences maximum shift of cyclic shift in direction opposite to driven pulley. According to the second version, the maximum interval is aligned along the line passing through the center of the driving pulley and the center of the driven pulley. According to the third version, the maximum interval is oriented relative to the output shaft.

EFFECT: reduction of vibrations during operation of drive pulley.
