Изобретение относитс к машиностроению и может быть использовано дл автоматического соединени и разъединени валов, в зависимости от их относительной скорости, в импульсных вариаторах, в автомобил х, в тракторах, в станках, в гидротрансформаторах и в др. машинах.The invention relates to mechanical engineering and can be used to automatically connect and disconnect shafts, depending on their relative speed, in pulse variators, in motor vehicles, in tractors, in machine tools, in torque converters, and in other machines.

Известна муфта, содержаща ведомую полумуфту, контактирующую с баллоном, заполненным жидкостью и соединенным с ведущей полумуфтой, имеющей пазы и взаимдействующей с подвижными порщн ми, воздействующими на жидкость в баллоне LlJ.A clutch is known, comprising a driven half coupling, in contact with a cylinder filled with liquid and connected to a leading coupling half, having grooves and interacting with moving forces acting on the liquid in the cylinder LlJ.

Однако така муфта не может быть применена дл автоматического соединени и разъединени валов в зависимости от их относительной скорости вращени в процессе работы.However, such a coupling cannot be used to automatically connect and disconnect the shafts, depending on their relative speed of rotation during operation.

Отли чительной особенностью описываемой муфты вл етс то, что баллон снабжен камерами , сообшаюшимис с ним и расположенными в пазах ведущей полумуфты, а в одной из стенок каждой камеры установлен упом нутый порщень, контактирующий с боковой The distinctive feature of the described coupling is that the cylinder is equipped with chambers communicating with it and located in the slots of the driving half-coupling, and in one of the walls of each chamber there is an aforementioned gap in contact with the side

поверхностью паза ведущей полумуфты прп передаче вращени .the surface of the groove of the leading coupling half, the transmission of rotation.

Кроме того, баллон выполнен металлическим , а его стенки, не касающиес поверхности ведомой попумуфгсы, вьшолыены жесткими .In addition, the cylinder is made of metal, and its walls that do not touch the surface of the slave popumufgs are chipped hard.

В такой муфте обеспечиваетс автоматическое соединение и разъед1шенпе валов при изменении их относительной скорости и муфта может работать как муфта свободного хода.In such a clutch, an automatic connection and release of the shafts is ensured when their relative speeds change, and the clutch can work as a free-wheeling clutch.

На фиг. 1 показана муфта в разрезе; на фиг. 2 - разрез по А - А на фиг. 1.FIG. 1 shows a sectional coupling; in fig. 2 shows a section along A-A in FIG. one.

Claims

The clutch contains a driven half ftu 1, to the inner cylindrical noBepxJiocTii of which the cylinder 2 is attached, is extended, ny. in the form of women. On the end surface of the balloon there are chambers 3 communicating with the balloon 2 through the openings 4, B. the internal cavity of the balloon 2 to the chambers 3 is filled with a liquid with a slight excess pressure. The balloon can be made of steel, plastic or rubber. The wall of the cylinder 2, adjacent to the driven half coupling 1, is made elastic, anti-friction pads 5 can be attached to it, Other walls of the cylinder 2 are rigid. In one wall of each chamber 3, there are holes 6 in which pistons 7 are hermetically mounted, having the possibility of axial movement. Instead of pistons 7, membranes or diaphragms can be used that are integral with the wall of chamber 3. Chambers 3 with pistons 7 are located in the slots 8 of the drive coupling half 9, while the pistons 7 adjoin 10 grooves 8 on the side surfaces. can touch not only the outer surface of the cylinder 2, but also its inner and end surface, while the corresponding walls of the cylinder must be elastic or rigid. Wallon can be filled with any known liquid, in particular hydroplast. When used as a hydraulic fluid, the sealing of the pistons 7 in the openings 6 of the chamber 3 is simplified. The sealing (sealing) is also simplified if the pistons are made in the form of a membrane or diaphragm. The clutch works as follows. When the leading half coupling 9 is rotated counterclockwise, the lateral surface 10 of the groove 8 presses the piston 7, which moves inside the chamber 3, increases the fluid pressure in the cylinder 2. Due to the elasticity of the cylinder walls, it increases in volume and its outer surface presses against the driven half coupling 1 The greater the pressure on the piston 7, the more forcefully the cylinder presses against the driven half coupling 1. The leading coupling half 9, the cylinder 2 and the driven coupling half 1 rotate as one rigid link. When changing the direction or decreasing the speed of rotation of the heads of the half-coupling 9, the coupling half erodes. As the side surfaces 10 of the grooves 8 of the leading half coupling 9 do not press on the pistons 7, the latter come out of chambers 8, the pressure in them drops and the cylinder 2 presses against the driven coupling half 1 with a small force, depending on the initial fluid pressure, the elasticity of the walls of the cylinder and coupling sizes. The leading coupling half 9 with balloon 2 freely rotates at a slower speed or in a different direction than the driven coupling half 1, the coupling is reversible, i.e. the coupling element may be the coupling half 1. Invention formula 1. The coupling containing the driven coupling half, in contact with the cylinder filled fluid and coupled to the master half coupling, which has grooves and interacts with movable pistons acting on the fluid in the cylinder, characterized in nnym grooves in the leading half of the coupling, and in one of the walls of each chamber is mounted said porschen in contact with the side surface of the groove eeduschey coupling half when transmitting rotation.

2. The coupling according to claim 1, characterized in that the container is made of metal.

3. Mufta on PP. 1 and 2, distinguishing us with the fact that the walls of the cylinder, which do not touch the surface of the driven coupling half, are rigid. Sources of information taken into account in the examination: 1. USSR Author's Certificate No. 115052, cl. F 16 D 43/284, 1958
