Zusammenfassung:FIELD: engines and pumps. ^ SUBSTANCE: invention relates to the two-stage belt transmission system to actuate the vehicle engine auxiliary equipment with the first and second transmission ratios. The system incorporates a clutch assembly fitted on the drive rotary shaft, a one-direction clutch fitted directly on the rotary shaft. The system incorporates also a good few rotary auxiliary appliances coupled to rotate along with the clutch assembly and, via the one-direction clutch, with the rotary shaft connected so that the said auxiliary appliances are driven from the clutch assembly with the first transmission ratio and actuated directly by the rotating shaft via the one-direction clutch with the second transmission ratio. The clutch assembly is designed to operate at a preset engine operating condition so as to set a transfer between the first and second transmission ratios. The clutch assembly is engaged on starting the engine up. ^ EFFECT: two-stage belt transmission, lower and narrower driving speed ranges. ^ 40 cl, 15 dwg, 4 tbl
