    For the operation of a diaphragm by a clutch release bearing, there is attached on the diaphragm an operating member comprising in the form of a single piece, an annular collar intended to act by means of a support face on the ends of the fingers of the diaphragm and at least two retaining shoulders adapted to secure it axially on the diaphragm. The retaining shoulders are turned axially in the direction of the support face of the collar. The support face, being curved, accommodates the bending of the fingers of the diaphragm. Advantageously the operating member is fitted onto the diaphragm without stressing any of the fingers thereof.

    This invention relates to mechanical engineering and can be used in vehicle diaphragm clutches. .
    The object of the invention in terms of the device is to improve performance by simplifying the design and increasing the reliability of fixing the support part relative to the clutch diaphragm.
    The purpose of the method of assembling the inclusion unit is to simplify it and increase its reliability by this means.
    FIG. 1 shows a clutch diaphragm placed on an annular support part in an axial section in FIG. 2; an annular support part in an axial section; in fig. 3 is a section A-A in FIG. 2j in FIG. 4 - isometric holding element; in fig. 5 shows the first step in connecting the diaphragm to the support part in FIG. 6 is a section BB in FIG. five; in fig. 7 shows the second step in connecting the diaphragm to the support part; in fig. 8 is a section bb of FIG. 7; in fig. 9 shows a variant of the first step of connecting the diaphragm with the support part; in fig. 10 shows a variant of the second connection step in FIG. 9; in fig. 11 shows embodiments of retaining elements; on . FIG. 12 shows an embodiment of FIG. 11 in isometry.
    The clutch engagement assembly (see Figs. 1-9) of the vehicle contains a release bearing 1 ton of the hardest type, which interacts with the diaphragm 2 in the direction of arrow F. The diaphragm 2 contains a disk washer located on the periphery and elastic plate fingers 4 integral with it. radially and forming an axial hole 5 in the center. The fingers 4 are delimited by radial slots 6 evenly spaced around the circumference with holes 7 at the base of the fingers 4 adjacent to the disk washer 3.
    The bearing 1 is connected with the free ends of the fingers 4 of the diaphragm 2 by means of an annular support part made in the form of a sleeve 8 with a radially located flange 9 having a bearing surface 10 facing the fingers 4 of the diaphragm 2 on the side opposite to the bearing 1. At the same time with the flange 9 At least there are two retaining elements 11 in contact with the fingers 4 on the bearing side: 1 and fixing the support part 8.9 in the axial direction, with respect to the diaphragm 2.
    The retaining elements 11 are made in the form of evenly spaced around the circumference of the support legs with
    Q radial sections 12, the supporting surfaces 13 of which are parallel to the supporting surface 10 of the flange 9 and with L-shaped elements, have the first section 14 located around the circumference, parallel to the supporting surface 10 of the flange the second section 15 located parallel to the axis of the diaphragm 2. the free ends of the 16 supporting legs 11 are located
    0 tangentially and associated with the second region 15.
    The width of the free end 16 is less than the sum of the width of the fingers 4 on the circumference of their location and the slot 6, with
    In this case, the rigidity of the end 16 is greater, the smaller its width. The support surface 10 of the i9 flange is provided in the form of a rounded annular protrusion formed by punching. The sleeve 8 can be made from a sheet of medium-.
    cutting and subsequent stretching. Sections 14 and 15, 15 and 16 and legs 11 are connected in pairs by two folds 17.
    Section 15 has a thickness less than the thickness of the workpiece sleeve 8 and less than the width of the slot 6 of the diaphragm 2. Thus, the diaphragm 2 is a single unit with an annular support part 8, which is convenient to use when connecting the clutch mechanism with the equipment.
    According to the embodiment (Fig. 10), the support ring part can be included without sleeve 8. In this case, the bearing 1 of the push type is used.
     The support flange 9 of the ring part in this case also has a support surface 10 in the form of an annular protrusion and is made with large radial dimensions to form a support ring 18 interacting with the bearing 1. The support ring 18 can be flat as well as the contacting surface bearing.
    5 With diaphragm 2, the support part contacts on the annular protrusion 10. The support legs 11 MAY be located on the periphery side

    surface of the flange, and from its inner surface, i.e. from the side of the axial bore 5.
    The last indicated variant is shown in FIG. 12, In this embodiment, a 1-ton bearing type is used, the support legs 11 respectively have a section 19 extending in the axial direction and a radial section 20. If the ring part has an axial sleeve 8 connected to the inner side surface of the flange 9, then the section 19 can be made at least part of its length in one piece with the sleeve. 8 and is made continuous in the circumferential direction. In this embodiment, the sleeve 8 is made with smaller axial dimensions and has the shape of a Venturi tube with two truncated cones on both sides of the orifice of reduced diameter located between them. The support surfaces 13 of the tabs 11 are also radially spaced from the sleeve 8. The described embodiment is most suitable for a self-centering release bearing 1.
    The support legs 11 in this embodiment can be obtained by cutting from the material removed to form the axial cavity of the sleeve 8.
    The method of assembling the clutch engagement assembly includes mounting an annular support part 8, 9 on the diaphragm 2, which is carried out as follows. First, axial movement of the sleeve 8 in the slits 5 of the diaphragm 2 is carried out and the ends of the fingers 4 are brought closer together with the flange 9 of the supporting ring part. Then fold three fingers 4, opposite the supporting legs 11, in the direction of the flange 9 and turn

    11 are located in slots 6 that divide the fingers 4. After connecting the diaphragm 2 to the support part 9, they constitute a single unit suitable for connection to equipment. Each finger 4 is in contact with the collar 10, which results in minimal wear.
    A single unit of the diaphragm 2 and the supporting ring parts 8.9 can be supplemented by the bearing 1..
    When connecting the diaphragm 2 and the support part 8.9, the fingers 4 can be bent in the direction opposite to the flange (Fig. 9). The bearing 1 can act on the diaphragm 2 and in the direction of this diaphragm (Fig.10), i.e. in the case of the use of the bearing t pressure type.
    The axial force for bending the fingers 4 can be created by the radial sections 15 of the supporting legs 11 (see. (Fig. 9).
    The assembly method of the assembly of FIG. 10 and 11 are essentially the same as indicated, but in the assembly method of the embodiment of FIG. 11, there is some distinguishing feature according to which the supporting surfaces 13 pass in the axial direction through the diaphragm 2, not because of its notch 6, but through the axial hole 5.
