    A friction clutch wherein, for pivotally mounting a plate spring thereof at a clutch cover, first bracing means are provided at the cover side of the plate spring and second bracing means are provided at the side of the plate spring facing away from the clutch cover and, for forming the second bracing means, holding means punched out of the material of the clutch cover and bent away extend through recesses formed in the plate spring, the holding means being formed from the cover by a punched-out section disposed in a direction selected from the group thereof consisting of a chord direction and circumferential direction of the cover and diverted so as to extend in a substantially radial direction and perpendicularly to the plane of rotation of the clutch.

    (5) Friction clutch
    one
    The invention relates to mechanical engineering, in particular to devices for transmitting rotation.
    A known friction clutch containing two half couplings and a friction 5 disk, compressed by a diaphragm spring f 1 J.
    Its disadvantage is the complexity of the design.
    Closest to the proposed to the technical essence and the achieved result is a friction clutch, comprising a housing with a ring-shaped support at the end and notches forming the figured elements, bent away and supported against the ring-shaped support of the housing, as well as a diaphragm spring, placed between the supports f2j.
    A disadvantage of the known clutch is the complexity of the design and low accuracy of the assembly.
    The purpose of the invention is to simplify the design and improve the accuracy of the assembly.
    The goal is achieved by the fact that the notches are located along the chord, and the figured elements are bent in the axial direction and located in the plane passing through the axis of rotation of the coupling.
    The body is made with radial notches in places of bends of figure elements.
    The support, located against the ring support, is made in the form of an elastic ring and is mounted on the free ends of the figured elements.
    Radial protrusions are made on the free ends of the figured elements, and the elastic ring is made on the inner surface, mounted on the figured elements and fixed against rotation.
    Radial protrusions made integral with curly elements.

    The surface of each shaped element in contact with the elastic ring has an increased hardness. 39 The coupling is equipped with wedge elements mounted between the radial protrusions of the shaped elements. and an elastic ring, the wedge elements being integral with the elastic ring and arranged one side circumferentially of the constricted part 8 with an elastic ring made with stops on the inner surface. The stops are made integral with the elastic ring in the form of radial protrusions. The stops can be made two-sided by them. FIG. 1 shows a friction clutch, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 view B in FIG. 2 (friction clutch part); in fig. C is a section B-B in FIG. 5 embodiment. The friction clutch consists of a body-cap 1, on which a diaphragm trailed spring 2 is rotatably supported on a pressure disk 3. As a support surface for a plate spring 2 on the lid 1 there is an annular support in the form of curved grooves located in In the circle, or ribs, and on the opposite side of the disc spring there is a support 5, which itself forms a support plane for the disc spring and is supported by shaped elements with protrusions 6 vayut disc spring to form a support for the diaphragm support § The shaped elements are formed from a lid la mother and are folded at right angles to the pivot plane of engagement. For easier and more accurate bending, a notch at the bend can be applied. The tray support 5 can be made of spring-loaded or elastic material and attached to the figure elements 6 by means of a wedge. For this talilchat part of the support 5 has a wedge-shaped protrusion 7. and the figured elements - in contact with him stop. For each of the shaped elements 6 in the support 5, a groove 8 is provided with which the ring, through these elements, is moved in the axial direction. The support has a protrusion 9 with a stop contour 10 for the tool for turning it. When turning, the protrusions 7 come into contact with the stops of the shaped elements 6. The projections 9 have gripping sections 11 for the tool, and with the reverse direction of rotation, the support 5 can be detached. In order to avoid the formation of rust during planting or wear, the figured elements 6 at the point of contact with the support 5 may have greater hardness than in other areas. This can be accomplished, for example, by surface hardening using induction heating, etc. , or drawing wearproof material. The shaped elements 6, which are the fixing elements, can be made of the material of the cover 1 by stamping slots (notches) circumferentially or along the chord, and bending them at least at a right angle in the plane passing through the axis of rotation of the friction clutch . Claim 1. Clamp coupling, comprising a housing with an annular support at the end and notches forming figured elements, bent and having a support located opposite the annular support of the housing, as well as a diaphragm spring disposed between the supports, so as to simplify design and increase the accuracy of the assembly, notches are located along the chord, and the figured elements are bent in the axial direction and are located in the plane passing through the axis of the rotary coupling. 1, that is, 2. Coupling according to claim y so that the body is made with radial notches in places of bends of the figure elements. 3. Mufta on PP. 1 and 2, about t that the support, put against ring-shaped support, is executed in the form of elastic; rings and mounted on the free ends of curly elements. . Coupling on PP. 1-3. characterized by the fact that at the free ends φ ((the solid elements are made of radial protrusions, and the elastic ring is mounted on figured elements and fixed against rotation. 5 5. The clutch according to item C, which is that the radial protrusions are integral with the figured elements, 6. Muff according to clauses 3-5 o t l and so that the hardness of the surface of each figurative element in contact with the elastic ring is higher than the hardness of the body. It is necessary that it is supplied on wedge elements mounted between the radial protrusions of shaped elements and an elastic ring 8. The coupling according to paragraphs 3-7, o.tlima with the fact that the wedge elements are made integral with the elastic ring 9. The coupling according to paragraphs 3-8, characterized in that wedge elements are located narrowed in one direction around the circumference. 1 10. The coupling according to paragraphs 3-8, characterized in that the wedge elements are arranged in different directions around the circumference with a narrowed suit. 11. Coupling according to paragraph 3 10, about t l and so that the elastic ring is made with stops on the inner surface. 12. The clutch according to claim 11, characterized in that the stops are made integral with the elastic ring in the form of radial protrusions. 13. Mufta on PP. 11 and 12, from the fact that the stops are two-sided. Sources of information taken into account in the examination 1. US patent number 3160253, cl. 192-89, 196.
