    A clutch cover assembly suitable for automotive vehicles comprises a generally annular cover by means of which it is adapted to be attached to a reaction plate or flywheel. It further comprises a generally annular pressure plate which is constrained to rotate with the cover but movable relative to it in the axial direction. Elastic means in the form of a diaphragm spring bear on the cover to exert an axial force on the pressure plate through a bearing member. The bearing member is centered on the diaphragm spring by axial lugs which engage in notches provided on the diaphragm spring for this purpose. The bearing member carries a progressively acting spring washer.

    With the feet 23 located in the recesses between the elastic fingers 18. Alternatively, the support part can be mounted on the disk by means of a pin. Elastic means of smoothness can be made together with the support part or in the form of separate elements.
    The invention relates to mechanical engineering and can be used in friction clutches.
    The aim of the invention is to simplify the design by using the support part to center the diaphragm relative to the pressure disc.
    FIG. Figure 1 shows the switching mechanism; in fig. 2 shows a section A-A in FIG. 1 in FIG. 3 is a view B in FIG. one; in fig. node I in FIG. 2; in fig. 5 - the same, the embodiment; in fig. 6 knot

    The activation mechanism comprises a flywheel 1 with gears fixed on it with a crown 2, a feedback disk 3 and a casing 4. The pressure disk 5 is rigidly connected to the casing 4 in the direction of rotation and is spring-loaded along the axis by elastic means of activation - a diaphragm 6. The friction disk 7 is located between the disk 3 feedback and pressure disk 5.
    The casing 4 has a bottom B, in which there is a central opening 9, a side wall 10 located generally along the axis, and at its end there are radial platforms 11 evenly distributed around the circle after 120, having holes in some places
    12 for fastening the cover 4 on the feedback disk 3.
    The pressure disk 5 is fixed to the casing 4 by means of elastically deforming plates 13, which are located almost tangentially to the circumference of the system (Fig. 2 and 3).
    Combi, fixed to the disk screw. The smoothness of the inclusion is ensured by elastic means, located between the support part and the disk. The axial displacements of the elastic elements are limited by the support of the shelves located in the grooves of the disk. 16 hp, f-ly, 1I silt,

    Three sets of such plates 13 can be used, which are evenly distributed around the circumference 120 ° from each other and which include each of the three plates 13 superimposed on each other.
    Each of these sets of plates 13 is fixed on one side to the tab 14 of the pressure disk 5, which projects radially in its outer peripheral part and to which it is attached by a rivet 15, and the other side to the radial platform 11 of the casing 4, to which it is also attached by a rivet sixteen.
    The rivets 16 not only provide the fixing of the sets of plates 13, but, in addition, rigidly connect the casing 4 to the feedback disk 3.
    The diaphragm 6, located between the pressure disk 5 and the casing 4, has a peripheral ring annular portion 17 forming the disc spring and, on the other hand, a central portion divided by slots into radial elastic fingers 18 through which it interacts with the deactivating support (not shown ) to loosen or release the friction disk 7.
    The peripheral part 17 of the diaphragm 6 rests on the bottom 8 of the casing 4, on which an annular shoulder 19 is provided for this.
    Since the casing 4 is formed by sheet punching, the shoulder 19 is the result of a simple stamping.
    Aperture 6 interacts with aa,. press drive 5 through the support ring part 20, which has for this purpose an annular flange 21. An annular flange 21 is obtained by simple
    forms a support ring part 20.
    As in the embodiments shown in FIG. 1-4, we are talking about a clutch of the n type, that is For a clutch, for which the attached stopping point (not shown) should work when the central part of the diaphragm 6, divided into radial fingers 18, is stretched in the direction along the axis of the pressure disk 5 to the bottom 8 of the casing 4, the diameter of the circle along which The support part 20, the diaphragm 6, acts axially on the pressure disk 5, smaller than the diameter of the circle on which it rests on the case 4.
    In order to center the diaphragm 6 on the wall 10 of the casing 4, stamped elements 22 are made (FIG. 2) arranged in places or continuously in a circle on the side wall 10 of the casing 4.
    To take advantage of this placement when mounting, the radius R of the outer peripheral contour of the support part 20 is not larger than the radius R of the opening 9 of the casing 4. In connection with this, the supporting part 20 and the casing 4 can be made of the same sheet blank, accordingly cut and stamped. In other words, the support member 20 is formed from what is usually waste when the casing 4 is made.
    The support piece 20 is centered with the axial legs 23 on the elastic switching means that rest on the casing 4 for axial action on the pressure plate 5.
    Axial tabs 23 are inserted into recesses 24 made between radial fingers 18 at their base near the inner peripheral portion of the disc spring 17. If the axial tabs 23 are three, they are evenly distributed in a circle through 120 ° on the inner peripheral portion 25 of the support part 20 ( Fig. 1 and 2). In this case, the side sections 26 (FIG. 1) can interact with the side contour 27 of the legs 23.
    Due to this, as soon as the axial tabs 23 of the support part 20 are inserted into the recesses 24 of the diaphragm 6, the support detail 20 automatically appears centered on the diaphragm 6. Since the support part 20 is located between the diaphragm 6, the center part

    In the casing 4, and the pressure disk 5 and a significant pressure force acts on it through the diaphragm 6, then no other means of fastening this support part 20 to one or the other of the parts is required.
    The activation mechanism has elastic elements formed in this case by a disk of a cup spring 28 located between the pressure disk 5 and the supporting part 20. Elastic means 28 are fixed on radial protrusions (Figs. 1, 2), which the support part 20 has on one of the its internal or external parts. The radial protrusions 29 are evenly distributed in a circle on the inner peripheral part 25 of the support part 20. There are two diametrically opposed internal radial protrusions 29 (Figures 1-4), with which elastic means of smoothness 28 are fastened with rivets 30. Due to this placement, the application elastic means of smoothness 28, in this case of a cup spring, greatly simplifies-. c, since it suffices to rivet the disc spring 28 on the support part 20 before mounting the system of two parts.
    FIG. 1-3, the engaging mechanism is depicted in the engagement position, and the disc spring 28 is depicted as flat due to the pressure force developed by the support piece 20 on which the diaphragm 6 rests,
    As soon as the mechanism is uncoupled (Fig. 4), the disc spring 28 again takes a non-operating position. Then the elastic means 28 formed by the disc spring disc exert pressure on the pressure disc 5 in the direction of the friction disc 7. There is a danger of the pressure disc 5 being rubbed on the friction disc 7 in the uncoupling position.
    The disc spring disc 28 is selected so that in the off position when disengaging there is no contact between these two parts.
    FIG. 5 shows an embodiment in which means are provided for limiting axial expansion when decoupling the elastic means of smoothness. In this embodiment, the elastic means of smoothness are made in the form of a disk 31 of the disc spring, have 5

    the inner radial protrusions 32 are evenly distributed in a circle on the inner peripheral part of the disk 31. Each protrusion 32 has a hole 33.
    The support part 34 has protrusions 35 evenly distributed in a circle, which also have holes 36.
    As shown in FIG. 5, the projections 32 and 35, as well as their openings 33 36, are opposed to each other. The piece 37 in the form of a chess pawn is riveted after being placed in each of the boring holes 36. The piece 37 has a cylindrical body 38 and a cylindrical head 39 of a much larger diameter. The housing 38 slides in the boring hole 33, while the head 39 performs the role of an abutment.
    The groove 40 is made on the pressure disk 5 against the radial protrusions 32.
    As shown in FIG. 5, in the unlocked position, the head 39 rests on the protrusion 32, thus limiting the axial expansion of the disc spring disc 31 when disengaging.
    FIG. 6 shows a variant in which elastic smoothness means are made integral with the support part 41, which is a disc spring disk, which has an annular shoulder 42 and axial tabs 43 evenly distributed in a circle on the inner peripheral part of the annular shoulder 42.
    Thus, the same part plays the role of a support part and means of smoothness.
    Means are also provided for limiting the axial expansion of the disk 41 of the prrulesine plate during disengagement. In this embodiment, they are formed by curved legs and a support part 41 interacting with grooves 45 on the inner surface of the pressure disk 46. In this case, each foot 44 has a radial section 47, located opposite the face of the 48 grooves 45 to interact with it when uncoupling. Paws 44 and grooves 45 are evenly distributed around the circumference.
    In the embodiment shown in FIG. 6, the support part 41 is centered on the pressure plate 46 by means of pins 49 pressed into the holes 50, which has a pressure

    disk 46, and holes 51, drilled in the protrusions 52 of the support part 41. In this case, the diaphragm 6 is centered on the pressure disk 46 using axial tabs 43, which have a support on the part 41, and axial tabs 43 interact, as in the variant the embodiment of FIG. 1-4, with recesses 24 between the radial fingers 18 of the diaphragm 6. In this case, there is no need to provide other alignment elements for the diaphragm 6.
    FIG. 7-11, two other embodiments are depicted in which the elastic means of smoothness 28 are not fully represented in an annular form.
     FIG. 7 and 8, the elastic means of smoothness 28 are elastic petals evenly distributed in a circle on the pressure disk 53. The elastic petals 54 (FIG. 8) have two end sections 55, which are in an idle state and are axially displaced with respect to the middle section 56, with which the end sections 55 are connected by inclined zones 57.
    Means are provided for limiting the axial movement of these lobes during disengagement, which are bolts 58 screwed into a threaded hole 59. Screws 58 pass through a hole 60 located in the lobes 54 in their middle part 56. The locking means are formed by the head of the screw 61 which abuts against disengagement in the middle section 56 (FIG. B).
    In this embodiment, the support member 62 has opposite screws. 58 cavity 63, made by stamping the corresponding zone of the support part 62 for the screw head 61.
    In the embodiment of FIGS. 9-11, the elastic means of smoothness are formed by petals 54, similar to those shown in FIG. 7 and 8. The means for limiting the axial nepeMenje of the petals 54 when disengaging is also formed by the interaction of the screw 58 with the petals 54 in the middle section 56.

    screw 61 is inserted into hole 64,
    which has the support part 65.
    In the embodiment of FIGS. 9-11, the screw head 61 of the floor has
    a polygonal fingerprint, for example, with six faces, for dismounting with a key of the same shape. This provides a convenient installation of the support part 65.
    In the embodiments of FIGS. 7-10, each petal 54 is fixed on the tab 14 of the pressure disk 5 by means of a rivet 15. For this purpose, a radial tab 66 is provided, rigidly connected to one of the end sections 55 of the petals 54 (Fig. 11 ).
    The device works as follows.
    The diaphragm 6, acting on the pressure disk 4, presses the friction disk 7 against the disk 5, as a result of which the rotation is transmitted. The smoothness of inclusion is ensured by elastic means 28 located between the support part 20 and the disk 5. The elastic means 28 can be made in the form of a conical ring, which pushes the support part 20 from the disk 5
    The centering of the support part 20 relative to the diaphragm 6 is carried out by the tabs 23, and the diaphragm 6 is centered in the casing 4 through the stops, extruded in the form of recesses 22.
    The axial displacement of the elastic element 31 is limited by a stop 39 or tabs 44 located in the grooves 45 of the disk 46.
