    This invention relates to mechanical engineering and can be used in vehicle clutches. Automobile clutch is known for containing two friction clutches each of which consists of a drive disk rigidly connected to a cylindrical body connected to a drive shaft. the possibility of axial movement relative to the drive disk and wedged on the corresponding drive shaft, the pressure disk installed in said housing with the possibility of axial movement relates of the drive disk and kinematically associated with the control, and conical strings of inert washers that are located facing each other and supported on one side: a stop element, located on the pressure discs, and on the other side on a corresponding supporting surface Pressure discs A disadvantage of the known clutch design is difficult assembly conditions. The purpose of the invention is to facilitate installation. This goal is achieved by the fact that in a clutch for an automobile containing two friction clutches, which consist of a drive disk rigidly connected to a cylindrical housing connected to the drive shaft, a friction disk mounted axially relative to the drive disk and screwed onto the corresponding a driven shaft, a pressure disk installed in the said housing with the possibility of axial movement relative to the driving disk and kinematically connected with the control element, and horses RP G schayby spring. which are located facing each other and supported on one side on the stop element located between the pressure discs, and on the other hand on the corresponding support surface of the pressure plates ,, the head-e element is made in the form of an o-ring located between the circumferentially conical spring washers, and on the inner cylindrical surface of the housing there is a retaining g: 1 element in the form of an annular stop or B in the form of a conical washer, set OBOB .jeiiHoii in the said casing IC-f, while holding the element mentioned spring;: a ring using axially arranged: these) segments fixed on the y-shaped body,): in the cylindrical case there are grooves for accommodating j3 of these mentioned segments, and for supporting conical and jayb cylindrical core ; clutch contains an additional annular stop. In addition, the annular stop of cylinder1 of the CHAIR of the case has a cross-sectional shape of a rectangular trapezium, moreover (5th AISES are pressed to the inclined IV-circularity of the stop. , top view (partial section A-A in Fig., 1); in Fig. 3, section B-B in Fig. Ij in Fig. 4, section B-B in Fig. 3; Fig. 5-section G-D in Fig. 3; Fig. 6 is a section view; - D in Fig. 3; Fig. 7 is a view of E in Fig. 3; Fig. 8 is a section in ZHZ in Fig. 7; pa; Fig. 9 - the first embodiment of the segment according to Fig. 8 | nt; on ita-ir, 11 - the same, the third option. The proposed clutch (Fig. 3) is double-disc and consists of drive discs 1 and 2, friction 3 and 4, connected to the hubs 5 and 6, respectively, with the possibility of axial movement and pressure plates 7 and 8, connected to drive plates 1 - 2, but axially movable to clamp the respective: 8A friction disc. The drive plate 1 has an almost cylindrical skirt 9 on its periphery, which extends axially around the friction and pressure discs and part of which is free has nasbi O and 11 (FIG. 2), forming between themselves the bases 12 (Fig, 7). The end section of these bases 12 of the drive disk 1 is axially but in alignment with the drive disk 2. Screws not shown in the figures and p1) passing through axial holes 13 in sockets 12s rigidly connect the drive disks 1 and 2. Pokoli 12 (FIG. 2) have a reduced height S and the skirt 9 has cavities 14 for favorable ventilation of the internal volume of the drive disk 1. Since the driving disk 1 has a body with a skirt 9, even cut out and empty, it forms a friction cover 3 and 4 and pressure 7 and 8 discs. The drive disk 2 (in the figures shown partially) is connected to the input shaft, while each hub 5 and friction disks 3 and 4 are connected to the driven shaft. Therefore, the hubs 5 and 6 have longitudinal splines on their inner periphery for gripping on the corresponding driven shaft. Each of the friction discs 3 and the clutch with two outlets and, thus, is mounted rotating on a separate driven shaft. However, if the clutch has one single output, then these two friction discs are mounted on the same drive shaft. Thanks to the grooves 10 of the skirt 9 of the drive disc 1 (Fig. 3), the radially extending legs 15 and 16 of the pressure discs 7 and 8 mounted axially into these grooves provide a rigid connection in the same direction as the pressure disks 7 and 8 rotate. discs 1 and 2, allowing axial movement of pressure discs relative to master discs. Between the pressure 7 and 8 and the leading 1 and 2 disks there are elastic means capable of moving these pressure disks in the hook direction, in which the friction disks and 4 are clamped between the pressure 7 and 8 and the leading 1 and 2 disks (Fig. 3). The two spring washers 17 and 18 of the type of disc spring elements are axially oriented in opposite directions and axially separated from one another by means of an expansion ring annular total 19 as a stop element mounted on the drive disk 1 and in opposite positions. x axially two support surfaces for spring washers 17 and 18. Each spring washer 17 and 18 of the proposed clutch rests with its outer periphery on the supporting shoulder of the spacer 19, and with its inner periphery on The appropriate pressure plate 7 or 8. For this purpose on each pressure plate has an annular flange 20 and 21 respectively. According to the invention, the spacer ring part 19 is made in the form of a simple ring with a transverse annular cross section, freely located between two spring washers 17 and 18, and for its axial installation on the drive disk 1, it is passed through at least one of these spring washers, abutted into annular support means located axially outside the said spring washer with respect to the spacer ring part and connected to the first disk 1 (Fig. 1-8). These annular support means are provided outside of one and the other spring washers and are designed as a shoulder 22 (Fig. 2 and 8). The latter is integral with the drive disk 1 and is formed on the inner surface of its skirt almost perpendicular to the axis of the coupling. With respect to the drive disk 1, the annular support means of the annular spacer 19 are fragmented into three segments of section 23, and each of them is attached to the drive disk 1 in one of the grooves 11, which has its skirt 9. Each segment 23 is connected by rivets 24 to a rod 25 , forming the bottom of the corresponding groove 11 (Fig. 2 to 8). The segments 23 project radially inside the skirt 9 of the leading disk 1, so that the spring washers 17 and 18 and the spacer 19, which they surround, are clamped between these segments 23 and the shoulder 22 of the drive disk 1. In this way, the spacer is axially joined. 19 with a drive disk on one side with the help of segments 23 through a washer 18, and the other with a shoulder 22 through a spring washer 17. A spring washer 18 directly contacts the segments 23, between which a ring can be located, and and the washer 17 is directly in contact with the shoulder 22 of the drive disk 1 (the ring may be located between the spring washer and the shoulder). The clutch contains a set of release arms 26 (in this case, three). Each release lever 26 is mounted on an axis 27, carried by two protrusions 28, which are provided for this purpose on the outer surface of the drive disc 1. The said release levers 26 extend almost radially from the periphery of the drive lead.
    the disk 1 in the direction of the axis of the coupling, and for their control, a release bearing of a clutch mounted on the axle is usually attached at their free end to them.
    According to the invention, the large levers 26 are in the form of a groove made of sheet metal, and in their internal volume there is a plate 29, which is mounted on the corresponding axis 27. By means of such a plate 29, each of the outer arm 26 is in contact with an intermediate lever 30, which Such a contact has a protrusion 31 and is mounted on the axis 32 itself, carried by the protrusions 28 of the drive disk 1 carrying the axis 27 of the release lever 26 (Fig. 3).
    The intermediate lever 30, through its free end outside the protrusion 31, contacts with the pusher 33, which passes axially with a gap through the drive disk 1 ,, screwed into the threaded hole 34 of the pressure disk 7 and contorts the locking nut 35,
    At the same time between the drive disk 1 and each release lever 26, at the free end of the latter, n: and closest to the periphery, there is a lever 36, mounted on the pin 37 and 38, carried respectively by the drive disk 1 and in the lever 26.
    In addition, the clutch contains three release arms 39. Each release lever 39 is mounted on a rotation axis 40 carried by one of the protrusions 28 carrying the axis of rotation 27 of the release lever 26 and a third protrusion 28 which is located on the outer surface of the drive disc 1 and is parallel to the previous one the protrusions 28 (Fig. 1).
    The squeeze levers 39 run almost radially from the periphery of the drive disc 1 to the coupling axis, parallel to the corresponding large lever 26, and for their control, a clutch bearing (not shown) mounted movably around the said axis is attached to them to their free end. At their free end closest to the periphery, the squeeze levers 39 each individually interlock with the pressure disk 8 with the help of stretching elements 41, which are fastened with the squeeze keys 39 and axially from the ground joint) 42 through leading 1 and pressing 7 and 8 71, and which are beyond pressure; -and) R () DISK 8 have an emphasis 43, made; in the form of a nut and lock nut, by means of which they come into contact with a pressure disk 8. Around each element 41. working on the tension between; 1 disk 1 and the release lever 39 is located on the spring 44.
     In all cases, the spring washers 17 and 18 operate independently of one another due to the fact that they rest on the spacer 19, which is mounted axially on the drive disk; In order to simplify the movement, the tilters 13 1nn that the spring washers 17 and 18 undergo during operation Some clearance is provided during their installation and the spacer part 19j which separates them between the shoulder 22 of the drive disk 1 and the segments 23 that support this installation with respect to the indicated drive disk.
    In addition, according to the embodiment (Fig. 9), for the same purpose, a truncated cone is attached to the shoulder 22 of the drive disk 1. A similar arrangement is taken for the corresponding shoulder of the segments 23, and such an arrangement can flow, as shown, from the deformation, which inevitably undergoes a corresponding section of said segments during their cutting into sections.
    Alternatively, the ring forming the annular spacer 19 is made in the form of a tile, i.e. equipped with one or several waves with an axis perpendicular to the axis of the installation, which allows smooth selection of the clearance provided in this installation. According to FIG. 1-9, the spacer part 19 is a simple ring that can be opened by means of a slit, and its circumferential ends are approached by gateways 45, directed outwardly parallel to one another and INPUT radially into passage 46 provided for this in skirt 9 of the drive disc 1 for the circumferential support of the specified spacer (FIG. 7).
    This support is not provided in this manner, for example, by simple friction, or by bald spots provided for this purpose on said spacer to work with bald spots made in series on the skirt 9 of the driving disc 1, and the circumferential ends of this spacer i ali can be deprived of any radial or axial returns or be connected to one another, for example, by welding
    As indicated, the axial installation of the spacer ring part 19 is provided outside the spring washers 17 and 18, therefore in both directions.
    In case one of the spring washers is more powerful (in the case of power take-off), it is sufficient that the axial installation of the spacer part 19 is ensured on one side i.e. in one direction, through the spring washer 17 or 18, the least weak, so that regardless of the speed the load of the spring, the strongest washer was higher than the load of the spring washer, the least weak. In this case, the very strong spring washer (without support from the side opposite the spacer ring part) constantly ensures that the spacer ring part 19 is pressed against the spring plate, the least weak, and through it to the support means located outside for this purpose (Fig. 10 and 11).
    FIG. 10 spring washer 17 vlets the strongest. Therefore, the segments 23 are provided outside the spring washer 18, and the shoulder 22 of the drive disk 1 is eliminated.
    In the embodiment of FIG. 11 spring washer 18 is the strongest. Only the shoulder 22 of the drive disk 1 outside the spring washer 17 is provided, and the holding segments 23 are eliminated.
    In all cases, spring washers 17 and 18 are axially opposed to each other and act, i.e. increase their load, independently of one another.
    Coupling works as follows.
    Under the action of the 5 flush clutch bearing, the release levers 26 move, in turn, turn the intermediate levers 30. By means of the pushers 33 on which they act, these intermediate levers 30 cause the axial movement of the pressure disk 7, which, moving away from the drive disk 1, meet spring washer 17, frees friction disc 3.
    This friction disk 3 is thus decompressed, and the corresponding output shaft is no longer connected when rotating with the input shaft, on which the drive disk 1 is mounted by means of the drive disk 2.
    When the proper clutch release plate ceases to act on the release levers 26, the spring washer 17 causes the clamping of the friction disk 3 again, and also, together with the springs 36, returns to the original position of the release levers 26.
    Under the action of the clutch release bearing, the release levers 39 are actuated, which are carried out by means of tension members 41 to retract the pressure disc 8. The latter in this case is removed from the drive disc 2 towards the spring washer 18.
    The friction disk 4 is rashy and the corresponding output shaft is no longer connected when wound up with the input shaft on which the drive disk 2 is mounted,
    When the proper clutch release bearing no longer acts on the release levers 39, the spring washer 18 causes the friction disk 4 to re-seize 1 and, together with pin 44, return to the initial position of the starting levers 3
    In addition, clutch release bearings connected to the start levers 26 and 39 can act simultaneously on the latter.
    . The invention facilitates the complexity of the clutch assembly by eliminating labor-intensive operations due to the simplified manufacture of previously difficult clutch parts. 11 6.-1
