    • 专利摘要:
    A plurality of elastic elements (11) extend radially inwards from an outer driven coupling part, and intermediate pieces (12), are located one between each adjacent pair of elastic elements (11), to form chambers for damping liquid between the elastic elements and the intermediate pieces. The tapered elastic elements have their radially inner ends fitting in axially extending grooves (16) in the periphery of a driving coupling part (20) and the chambers (13, 14) are bounded at their ends by closure walls and, in operation of the coupling, the damping liquid can be displaced through gaps between the elastic elements and one of the closure walls from the chamber (13) to the chamber (14). The elastic elements (11). the intermediate pieces (12) and an outer ring (10), comprise a one-piece member, with minimum rotary mass, or may consist of a laminated set of one-piece members fixed together face to face. <IMAGE>

    FIG. 1 shows a clutch, generally view, in section A-A in FIG. 2; in fig. 2 is a section BB in FIG. one; in fig. 3 - section along elastic elements; in fig. 4 - pressure line; in fig. 5 and 6 are options for measuring the width of the gap to increase or decrease the hydraulic chambers mechanically; in fig. 7 is a variation of the variation of the width of the gap with the help of a piston, driven by a pressure medium in FIG. 8 - change the width of the gap using a friction disk, option; in fig. 9 is a cross-section of the FIG. 10 along elastic elements with holes for supplying the working medium; in fig. 10 is a section B-B in FIG. 9, with the connection of the hydraulic chambers to the annular pipelines; in fig. 11 and 12 seals of adjacent hydraulic chambers, options.
    The elastic coupling contains the leading coupling half 1 and the driven coupling half 2, knowing the coupling half contains elastic elements 3, intermediate inserts 4 and outer ring 5, made as a single unit, and flanges 6 and 7. Elastic elements with intermediate inserts are installed with a gap and form cavities of hydrochambers 8 and. Which, with their walls 10 and 11, perceive the pressure of the fluid and can be made parabolic. On the outer surface 12 of the leading half coupling 1 there are spline-shaped grooves 13 of circular section in which cylindrical bodies 14 are located, and in them are placed the ends 15 of elastic elements, which can be made convex (Fig. 3). The elastic elements 3, the intermediate insert 4 and the ring 5, made as a whole, in the axial direction can be made of composite, for example, of three parts 16-18. In order to transmit the torque smoothly at high speeds, the working chamber from the independent pressure line 19 connected by means of the stationary support 20 with the half coupling 1 is fed into the hydraulic chambers 8 and 9.
    The elastic characteristics of the coupling are achieved by the fact that the widths of the gaps 22 between the adjacent chambers 8, 9 are mechanically, hydraulically or pneumatically adjusted. The flange 7 houses a piston 23, with which the gap 22 is changed by the pressure of the working medium and springs 24. Instead of a piston, an elastic disk 25 can be used. On the disk 25 a small piston 26 is fixed, which moves in the cavity of the cylinder 27 of the external flange 7 and is powered by an independent pressure line 19. If, the piston is unloaded, i.e. removed from it
    pressure, the disk 25 with the help of the return spring 28 enters the cavity 29. In the hydraulic chambers 30 and 31 (Fig.9, 10), the working medium is supplied and discharged through the regulating holes 32 and 33 from the annular pipelines 34 and 35 between the intermediate inserts 4 and the driving floor With the coupling 1, fork shaped seals 36, made of spring steel, are placed, and the sealing strips 37 and 38 are unfolded to the outside during installation, while the coupling is working under the pressure of the working medium, they are pressed against the outer surface of the coupling half, increasing the sealing of the hydraulic chambers. Fork-shaped seals can be made of rubber, they also attach to the leading coupling half 1, improving sealing.
