    A friction clutch comprises a cover member (11) a pressure plate (13) mounted to the cover member by drive straps (21) and a diaphragm spring (12) interposed between the cover member and pressure plate so as to urge the pressure plate towards and into frictional engagement with a driven plate. The diaphragm spring 11 has the usual outer belville portion (14) and inwardly projecting fingers (15). The outer parts of the fingers themselves and particularly the junctions with the belville portion are stiffened by stiffening ribs (31) which resist finger bending and thus reduce release travel. The ribs (31) extend into and terminate within the belville portion without reaching its outer periphery. Fulcrum rings such as 1 incorporate raised bridge portion to provide clearance for the ribs.

    has an outer annular part 5 and fingers 6 with stiffeners (RJ) 20. On both sides of the MP 2 there are annular hinges 8 and 9 in contact with it along an annular swivel line 7. The annular hinge 9, located on the side of RJ 20, can be filled intermittent intersection with them. On the hinge there are arched areas located above RJ 20 with a gap.

    The invention relates to mechanical engineering and can be used dp separation and a smooth connection of two coaxially rotating shafts.
    The purpose of the invention is to improve the performance characteristics of the friction sleeve by increasing the stiffness of the fingers of the membrane spring and connecting them to the outer annular part without significantly changing the performance characteristics of the membrane spring.
    1 shows a section aa in FIG. 2; Fig. 2 is a composite image of the coupling, the left half of which corresponds to the view of Fig. 1, and the right is a modification of this coupling; on fig.Z - part of the membrane spring; figure 4 - section bb in figure 2 (enlarged scale); Fig. 3 shows a composite image of a membrane PR: / VEIN with three options for the placement of stiffeners; figure 6 is a variant of the device in which the ribs on the diaphragm spring are located on the side of the pressure disk.
    The friction clutch shown in Fig. 1 and in the left half of Fig. 2 comprises a stamped steel casing 1, a diaphragm spring 2, a slave 3 and a pressure 4 disks. The diaphragm spring 2, also shown in FIG. 3, includes an outer spring annular part 5 and fingers 6 directed inward from it. The spring 2 is mounted in the case 1 around the circumference 7 formed by two annular hinges 8 and 9, the latter and the diaphragm spring 2 are installed in casing 1 with curved legs 0 constituting a single
    In the casing 1, there are cutouts 25 for accommodating the RJ 20. The last and arched sections can be directed from the MP 2 both towards the casing 1 and towards the pressure disk 4. The stiffening ribs on the fingers 6, which are in contact with the hinges 8 and 9, allow fully engage the clutch with a smaller displacement of the bearing 19. 5 Cp f-ly, 6 ill.
    a whole with a casing 1. The tabs 10 pass through the mounting holes 11 of the fingers 6 (the mounting holes 11 are shown in FIG. 3).
    5 The pressure disk 4 is mounted coaxially with the casing 1 and connected to it by means of three drive belts 12 located between the pressure disk 4 and the mounting points 14.
    0 of the casing 1. The belts 12 have sufficient flexibility, which provides limited movement between the casing I and the pressure disk 4.
    The outer annular part 5 of the membrane spring 5 2 presses the pressure
    the disk 4 relative to the casing 1 to the flywheel 15,
    As shown in FIG. 1, the housing 1 is mounted on the flywheel 15 and mounted
    0 thereto by an external flange 16 and installation bolts 17, the Slave disk 3 is installed between the pressure disk 4 and the flywheel 15 with the possibility of frictional engagement of the latter with the friction surfaces 18 of the driven disk 3.
    The clutch is disengaged by a release bearing 19 mounted on a driven shaft (not shown).
    0 As shown in FIGS. 3 and 4, as well as in the upper part of FIG. I, the membrane spring 2 has protruding stiffening ribs 20 located radially along the axial lines of the fingers 6. The ribs
    5 20 are formed as a result of stamping, in which on one side of the spring recesses 21 are formed, and another - protruding ribs 20 that cross the entire narrow part of the base.

    holes 11, ending within the outer annular part 5 of the spring 2.
    1-3, stiffening ribs 20 occupy approximately one third of the outer annular portion 5 of its inner edge, which is determined by the outer edge 23 of the holes 1 1, It is preferable that this distance be 25-50% of the outer annular portion 5. As shown in FIG. 3, said stiffening ribs 20 also extend in the inner direction, going beyond the internal boundaries of the mounting holes 11.
    As shown in Fig. 1, in the left part of Fig. 2 and in Fig. 4, the annular hinge 9 is provided with a series of protruding arched portions 24, while in the case 1, small notches 25 are provided that serve as recesses to accommodate the protruding arches 24. At least part of the cutouts 25 corresponds along its length to the lengths of the protruding arched portions 24, which ensures the placement of the hinge 9 with regard to rotation relative to the axis of the coupling. The deviation in the design of the annular hinge 9 from the usual type and the use of modification of the casing 1 do not affect the installation of the membrane spring 2 inside the casing I, since the main installation areas provided for the legs 10 are located between the fingers 6 and the corresponding ribs 20. Another option for placing the protruding arched portions -24 is a variant according to which grooves (not shown) are formed in the casing 1 by stamping.
    The right part in Fig. 2 corresponds to the third variant of intersection by the stiffening ribs 20 of the annular hinge 9. The latter are carried out in separate sections 26, each of which passes under the tab 10 and ends, not the income to the fin 20, to form gaps 27 for them. Sections 26 are attached to sheath I by spot welding, although they can be fixed to membrane sheath 2, for example, by means of epoxy glue.
    Figure 5 shows a composite image of parts of the membrane spring 2, showing three possible modifications to the design of the ribs 20. In the upper part of figure 5, two edges are shown
    28, which completely intersect the outer annular part 5 of the membrane spring 2. In another modification, shown in the central part of Fig. 5, the ribs 29 approach a very close distance to the outer border 30 of the spring 2, gradually decreasing its width and height as it approaches 10 and ends within the outer annular part 5. The lower part of Fig. 5 shows shortened ribs 31, which occupy only 25% of the transverse distance of the outer annular part 5.
    FIG. 6 is a view corresponding to FIG. 4, showing a modification in which the stiffening rib 32 faces in the opposite direction — 20 of the SRI, i.e. in line pressure disk 4, not shown in Fig.6. The rib 32 is formed by stamping, as a result of which a recess 33 is simultaneously formed.
    25 The hinge 34 on the opposite side of the diaphragm spring 2, held down in the desired position by means of the tabs 10, has protruding arched portions 35, and the annular hinge 30 36 is flat with no arched portions. The rest of the coupling corresponds to the devices shown in figures 1 and 2.
    The friction clutch works as follows.
    To turn off the clutch, the thrust force from the VYG1F1OGO bearing 19 is transmitted to the ends of the fingers 6 of the diaphragm spring 2, causing them to shift in the direction of the flywheel 15. The shifting of the fingers 6 causes the diaphragm spring 2 to rotate relative to the support rings 8 and 9, resulting in an external. the ring part 5 departs from the clamping disk 4, releasing the driven disk 3.
    Performing on the fingers 6 stiffening ribs 20 located radially along their axial lines, occupying 0-25 - 50% of the outer annular part 5 and extending beyond the inner borders of the mounting holes 11, increases the rigidity of the fingers 6 and connecting them to the outer annular gg part 5, not significantly reducing the performance of the latter. The presence of pins 6 with increased rigidity allows for complete deactivation of the clutch with a smaller displacement of the release bearing 19, which corresponds to a smaller clutch feed stroke or less force on it.
    The distance that the stiffening ribs 20 intersect the outer annular portion 5 can vary over a wide range. However, to ensure effective stiffness of the transition between the fingers 6 and the outer annular part 5 of the membrane spring 2, it is preferable that the fins 20 occupy a distance of 25 to 50% of the width of the outer annular part 5 of the membrane spring 2.
