    A shaft coupling assembly having a first and a second internal fluid chamber system, each containing therein a fluid medium which is placed under pressure when torque is transmitted through the coupling assembly, each of the fluid chamber systems including a plurality of chambers and a plurality of channels which converge from a common point placing the channels in flow communication with each other and which interconnect the plurality of chambers of each of the systems. The channels of the first and the second systems are axially offset relative to each other and each of the systems is designed to create a throttling effect offering resistance to flow of the fluid medium within each of the systems. The coupling assembly enables compensation for axial, radial, angular and/or torsional shaft offset and, additionally, makes it possible to damp the vibrations in an axial, radial, angular and torsional direction and to adjust the stiffness of the coupling assembly.

    This invention relates to vehicles, in particular elastic hinges.
    The purpose of the invention is to provide compensating and damping abilities.

    The elastic hinge comprises a hub 1 on the drive side, a hub 2 and a cylindrical body 3 with at least three holes 4 evenly spaced around the circumference, in which rubber-metal figured inserts 5 and 5 are installed.
    The hub 1 is connected to the body 3 of the hinge by means of screws 6, and the hub 2 is connected by means of bolts 7 and nuts 8 to pressed rubber-metal figured contributions 5. Each figured insert 5 is made with two protrusions 9 on the lateral surface, forming a jumper in each fiber which are located two cavities 10 11, filled with the working medium and
    environment. Torque is transmitted from | one hub to another through rubber-metal elastic figured inserts of the hinge body. 12 hp f-ly, 16 ill.

    connected by channels 12 and 13. Channels 12, interconnecting one of the cavities 10 of each hole 4, are made in the form of a system of channels star-shaped at the point, and channels 13 connecting the other cavities 11 of holes 4, made in the form of a system of channels, starlike converging at another point, and displaced axially relative to the first channels.
    The hinge is provided with means of providing resistance to the flow of the working medium, which are at least partially located in the channels. All channels 12 and 13 of both systems are radially and closed from the outside by means of screws 14 or plugs 15.
    The means of resistance to flow can be located at the junctions of the channels and made in the form of a s-. 16 cross sections of the channels (FIGS. 12-16) or in the form of rotary bushings 17 with converging to the center. channels 18 corresponding to the channels of the housing. The bushings 17 are installed in cylindrical holes 19 formed in the housing 3, and the points of connection of the channels 18 are located on the axes of the cylindrical holes 19 or on the axis of the housing 3.
    Between the two liners 5 of the housing 3 can be located one channel 11 or 12 of each of the systems of channels, and one channel 12 of one system can also be located, and between ONE of these contributions and adjacent to it. One channel 13 of another system.
    In each cavity 10 and 11 there is a rubber or rigid stop 20. The hinge body 3 is made of plastic with fibrous filler or polyester resin reinforced
    fiberglass, fiberglass tape or cloth seals.
    At least a partial adhesive coating, preferably of resin or polyester resin, is applied to the outer surface of the housing.
    At one diameter of the location of the inserts 5 in the housing 3, holes 21 are made, which serve to install the hub on the housing 3 by means of bolts 6.
    Glycol or silica oil can be used as the working medium filling the systems of channels 12 and 13. The working medium can be redistributed within the same system, but not between channel systems. By varying the diameters of the channels 12 and 13, one can achieve a predetermined throttling of the pulsations of the working medium, i.e. a certain level of damping.
    The baffles formed by the protrusions 9 of the liners 5 can be deformed under the pressure of the working medium, and one of the cavities of one hole 4, for example cavity 10, is larger than the other cavity 11 of the same hole 4. The stops 20 limit the deformation of the jumpers. By means of the rotary sleeve 17, it is also possible to regulate the throttling of the working medium and, accordingly, the damping capabilities of the structure. ,
    Channels 12, 13 and 18 are sealed relative to each other and externally by means of sealed rings 22, therefore the separation of the channel systems of the rotary sleeve is not disturbed and leakage is prevented. The rotary sleeve has a hexagonal head 23, with which you can adjust its position. Two additional slewing sleeves 24 can be installed.
    Torque is transmitted from hub 1 through screws 6 and rubber-metal inserts 5 to body 3, then through bolts 7 to hub 2.
    Damping can be adjusted in both directions of torque transmission.
    Dependencies (figure 1) characterize the hinge, the cavities and channels of which are completely filled with liquid under a pressure of 1 bar. If the systems contain small impurities of air, the characteristics will be softer, i.e. it is displaced into the area under the line b in the direction of the characteristic a of the hinge without liquid filling. If the fluid is compressed under pressure, the hinge will be stiffer, i.e. the characteristic with increasing pressure of the liquid is shifted from line b to line c.
    Fig. 2 shows a plot of fluid pressure in a loaded system versus torque transmitted by a hinge. The torque value of 400 Nm corresponds to the pressure in the cavity of approximately 20 bar.
    . FIG. Figure 3 shows the dependence of the damping acting at the hinge, expressed as the phase angle, of the excitation frequency. With increasing frequency, the damping increases too disproportionately. This growth is based mainly on the increasing proportion of damping at the expense of the liquid, since the proportion of rubber in the frequency range covered only slightly changes. The graph shows two experimentally obtained hysteresis loops at a frequency of less than 10 and 70 Hz. At low frequency, damping is determined solely by rubber. The fluid is completely excluded and does not affect the damping. Conversely, at a frequency of 70 Hz, the hysteresis loop expands significantly. The increase in damping is due to the effect of fluid damping.
