    1 The invention relates to mechanical engineering, in particular to vehicle transmissions. The purpose of the invention is expansion. Transmission Functionality FIG. 1 is a schematic diagram of the device for controlling the transmission ratio of the continuously variable V-belt transmission in FIG. 2 shows an embodiment of a control valve. The device for controlling the transmission by the precise ratio of the continuously variable V-belt transmission - contains driving and driven shafts 1 and 2, each of which is equipped with conical disks 3-6, o6pa3yMnpie pulleys covered by a V-belt 7. The conical disks 4 and 5 are axially mounted movement under the action of the pressure of the working fluid supplied by the pump 8 through the admission valve 9 and the control valve 10 to the hydraulic cylinders 11 and 12, and the disk 4 is a piston for the cylinder 11, and the disk 5 a piston for the cylinder 12. Overflow valve 9 coder It is a spring-loaded spool 13, provided with two cavities 14 and 15 of control, a cavity 14 with a pump 8, and a cavity 15 with a pitot tube 16, with the spring 17 of the valve 13 interacting with a conical disk 4 The control valve 10 contains a spring-loaded spool 20 with two control cavities 21 and 22, while the hollow 21 communicates with the pump 8, and the cavity 22 with the Pitot tube 16 and two working edges 23 and 24, communicating the hydraulic cylinder 11. with the pump 8 or with a drain. 25, moreover, the spring 26 of the valve 20 through the element 27 of the interaction with the software cam 28. The pitot tube 16 is placed in the projection rte-29 of the hydraulic cylinder 11, communicated through the opening 30 with the working volume of the hydraulic cylinder 11. 65 2 In an embodiment of the control valve 10 (Fig. 2) the latter has only one control cavity 22 connected to the pitot tube. 16, and an additional piston element 31, the piston 32 of which is located inside the spool 20 and spring-loaded spring 33, the spring cavity 34 through the opening 35, and the springless cavity 36 through the opening 37 communicating respectively through the control valve 10 with the drain 25 and the pump 8, and element 31 through the stopper 38 and the additional spring 39 interacts with the element 27. The device operates as follows. The gear ratio is determined by the force of tightening the spring 26 of the valve 10 controlling the displacement of the cam 28, as a result of which the position of the spool 20 is determined by the ratio of the forces of the spring 26 and the pressures in the cavities 21 and 22. When the speed of the output shaft 2 deviates from setting-. At a given position of the cam 28, the magnitude of the hydrodynamic pressure of the fluid in the protrusion 29 and, respectively, in the control cavities 15 and 22 of the overflow valve 9 and the control valve 10, the movement of the spools -13 and 20 of these valves, as well as the pressure change in the cylinders 11 and 12 and the movement of the conical disks 4 and 5V and the belt 7 with the transition to a new gear ratio, at which the spools 13 and 20 will be in equilibrium. The position of the spool 13 is corrected by the position of the disk 4 through the pull 19 and the lever 18. In the embodiment of the control valve 10 (FIG. 2), the position of the spool 20 is further corrected by changing the position of the element 31 and the ratio of the forces of the springs 33 and 39 by changing differential pressure in the cavity 34 and 36 of the spool 20.
