FIELD: engines and pumps.
SUBSTANCE: invention relates to control over variator pulley axial force. Proposed device comprises torque transfer endless element wound around two pulleys, transmission working mode selector and programmable controller. The latter defines stretching of said endless element proceeding from transmission working mode and axial force for limitation of slippage in compliance with the magnitude of stretching. Besides, this controller controls axial force for one of said pulleys for limitation of slippage in compliance with the magnitude of stretching. Besides, this invention relates to control over gear ration of above described transmission.
EFFECT: adequate control at stretching of endless drive.
