    A diaphragm spring clutch in which the diaphragm spring is secured to the cover member by posts, or a clip ring. Centering studs distinct and independent of the posts or clip ring are carried by the cover member for centering the diaphragm spring on the cover member. Enlarged passages are provided at the radial inner ends of slots between consecutive finger portions of the diaphragm spring, the enlarged passages being of oblong configuration with opposed radial sides, and the centering studs being in contact with portions of the edge defining the enlarged passages.

    I
    The invention relates to the field of machine-building technology, in particular to devices for transmitting rotation.
    A friction clutch is known, which contains a diaphragm spring 5 fixed on the housing and a pressure disk {1.
    The disadvantages of it are large weight and size.
    A friction clutch is known that contains a lid with assembly jq pins fixed on the flywheel, a diaphragm spring with radial slots, and a pressure disk moving in the axial direction, and the assemblies are located in the slots of the diaphragm spring 2.j5
    This device is closest to the invention in its technical essence and the achieved result.
    The disadvantage of it is low durability. -20
    The aim of the invention is to increase the durability of the clutch.
    The goal is achieved by the fact that the friction clutch is fitted with centering on the cover parallel to its axis25
    pins with heads placed in the slotted diaphragm spring.
    FIG. 1 shows a friction clutch, top view; in fig. 2 - view A of FIG. one; in fig. 3 - section bb FIG. one; in fig. 4 - node G of FIG. 3; Fig. 5 shows a section bb of fig. four; in fig. 6 shows a clutch version.
    The friction clutch contains a cover 1 and aperture 2.
    On the periphery of the cover 1 has a flat sections 3, which are attached to the flywheel 4 (Fig. 3), and flat sections 5, axially shifted relative to the first, which it can be coupled with the pressure disk 6.
    The disk 6 is connected to the lid 1 by plates 7, which at one end are attached to the flat sections 5 of the ridge I by means of rivets 8, and the other are rigidly connected to the pressure disk 6 by means of screws 9 mounted against the holes 10 in the crink-bolt 1 allowing installation these screws.

    The peripheral part of the diaphragm 2 forms an elastic ring such as a Belleville ring, with which it is in contact with the pressure disk 6. The central part of the diaphragm is divided into radial petals 12 of the slits 13, which at the base of Petals 12 pass into the oblong holes 14. For connecting the diaphragm with the lid 1 an assembly device is provided, comprising a ring 5, which is installed between the diaphragm 2 and the lid and is centered relative to the axis of the block with the help of shoulders, made for this purpose on the core 1, for example, by stamping, and the number The end part, in this case, the crown 16, which is placed on the other side of the digfgram 2 opposite the lid f and interlocked with the latter with the fingers 17. In the central part of the thing are the holes 18 for the passage of the fingers 17. The periphery on the crown part 19 has the shape of a groove Click on the diaphragm 2 at a right angle. The finger 17 has a head 20, with which it rests on the lid I, and a rod 21 mounted in the hole 22 and in the lid 1 and the passage of the shield simultaneously through the holes 14 and 18. The finger 1. outside the crown 16 compressed. The plates 7, which, while rotating, rotate the pressure disk 6 with the wing 1, allow the disk 6 to move in the axial direction so that under the action of the diaphragm resting on the cover 1 through the opening 14, it can press the friction disk 23 to the flywheel 4 new between 6 and a flywheel 4. A release bearing (not shown) is acting on the ends of the radial lobes of 12 D1fragms 2. The clutch contains means for centering the diaphragm 2 relative to the clutch axis, which are made separately from the assembly tools in the form of centering pins 24 mounted on the lid parallel to its axis in contact with the edge of the diaphragm 2. Centering pins 24 have a head 25 that fits 14 diaphragm 2 and resting at least on one of the sides 26 of this opening. The core. 4 27 gears rigidly mounted in the hole 28, | made in the lid 1. In addition, it can be made with a threaded section with a clamping nut. The centering pin 24 also has two flanges 29 and 30, with which it compresses the cover 1 and, therefore, is rigidly connected to it. In order to effectively ensure the constant centering of the diaphragm 2 relative to the axis of the block, three centering pins 24 are sufficient. in the diaphragm 2, and then go beyond the crown 16, where they are bent, before contact with the latter. The crown 16 has a groove, and the support roller 33, designed to support the diaphragm, is stamped on the lid I. Segments 31 alternate with centering pins 24 and may have legs made integral with one cap 1. Claim 1. Friction clutch comprising a cover fixed to the flywheel with assembly pins, a diaphragm spring with radial slots, and also movable in axial direction a disk, wherein the assembly pins are placed in the recesses of the diaphragm spring, characterized in that, in order to increase the durability of the coupling, it is provided with centering pins attached to the cover parallel to its axis heads placed in the slot x diaphragm spring.
