AUTOMATIC EDGE VEHICLE VARIATOR OF SPEED1 The invention relates to the field of mechanical engineering and can be used in machine drives that require constant angular velocity of the driven shaft while reducing the speed of the drive motor. centrifugal weights for automatic adjustment of the speed of the driven shaft. The proposed variator is characterized in that the centrifugal weights are equipped with tymi gears mounted on the shafts located in the hub is fixed conical disc. The hub of the movable conical disk is equipped with toothed racks, interacting with them with gears, and inside this hub there is a hydraulic cylinder with a piston, provided with holes and rigidly mounted 20 on the shaft. The automatic V-rim speed variator contains a leading / and driven 2 shafts, fixed 3 and movable spring-loaded 4 tapered discs, a device with centrifugal weights 5, equipped with gear gears 6, which are mounted on axles 7 located in the hub of one fixed tapered disc 3. The hub of the movable di Ska 4 is equipped with toothed rails 8 that interact with gears 6, and inside this hub there is a hydraulic cylinder with a piston 9 equipped with holes and fixed on shaft 2. The described speed variator works as follows. At the nominal angular velocity of the drive shaft / weights 5 are in a horizontal position, while the diameter of the belt 10 of the driven shaft 2 is minimal. As the angular velocity of the drive shaft increases, the speed of the driven shaft increases. The weights 5 under the action of centrifugal inertial forces rotate about their axes and force the movable disk 4 to move, thereby increasing the diameter clinging to the V-belt 10 and reducing the angular velocity of the driven shaft 2.
