    A wet friction clutch for automotive vehicles wherein the clutch plate between the flywheel and the pressure plate is assembled of two spaced-apart friction discs and a spacer disc therebetween. The friction discs are coupled to each other by leaf springs which prevent relative angular but allow relative axial movements of the two friction discs. Additional leaf springs connect the spacer disc and the pressure plate to the cover, and elastic lamellae are used to couple the two friction discs to the flywheel and the pressure plate, respectively. The clutch plate drives the input shaft of the transmission and carries a distributor for lubricating coolant which is supplied by a tubular guide for the disengaging unit and serves to cool the friction discs.

    The invention relates to mechanical engineering, in particular to devices for transmitting rotation. . A friction clutch for automobiles is known, which contains a casing mounted on the flywheel, a naskimny disk mounted in it and a friction disk located between it and the flywheel l J. The disadvantage of this clutch is low load capacity due to the presence of only one friction disk. The closest to the invention to the technical essence and the achieved result is a friction clutch for automobiles containing a casing fixed on the flywheel, mounted therein with the possibility of axial movement of the pressure disk and at least one intermediate plate, between them friction disks, connected with a sleeve mounted on the shaft through the base, and a disc spring mounted between the casing and the pressure disc. The known adhesion is reliable in view of the insufficient contact of the friction surfaces during switching on and their interaction when disconnected 21. The purpose of the invention is to increase reliability by improving the contact of friction surfaces at switching on and their dilution when disconnecting. The goal is achieved by the fact that the friction clutch for automobiles contains a casing fixed on the flywheel, mounted in it with the possibility of axial movement of the pressure disk and at least one intermediate plate, friction disks located between them, connected to an axle-movable axle mounted on the shaft through the base, and the disk spring, mounted between the casing and the pressure disk, is equipped with flat springs that are hinged at their ends with friction disks, which fixes them from rovorota at ztom friction discs mounted for axial displacement relative to one another. The flat springs are mounted between the friction discs with a pre-jbiM compression stress. 782 In addition, the clutch is provided with axial-force flat springs located between the friction discs in the axial direction. Limiters can be made adjustable. The axial stroke of the friction discs relative to each other is equal to at least half the axial stroke of the pressure disc. Moreover, one friction disc is connected to the sleeve by a base, and the other friction disc is mounted on the base with the possibility of axial movement by means of flat springs. . The restraints can be rivets fixed on one of the friction disks and located in the holes of the other friction disk - with their heads resting on the surface of the latter. Flat springs are attached to one of the friction discs using the stops. In this case, one of the friction disks is made with protrusions directed radially to the center for fastening the stops. FIG. 1 shows the clutch in the engaged position, the slit; in fig. 2 of type a in fig. 1. The clutch is mounted on a flywheel 1 having a bearing surface 2. The base 3 has two friction disks 4 and 5, between which there is an intermediate plate 6 and a pressure disk 7, which presses the disks to the supporting surface 2 using a disc spring 8 supported by one on side cover 9 ,. and on the other, to the pressure plate 7. The base 3 has a sleeve 10 common to both friction disks mounted on a 1 G drive shaft through a splined engagement so that it can be axially displaced along the shaft. The carrier disk 12 of the friction disk 4 is made integral with the base 3 and has friction linings 13 on its periphery on both sides. lining 16. The disk 15 and the carrier disk 12, and the friction disk 4 are interconnected
    flat springs 17 rigid in the direction of rotation and elastic in the axial direction. The springs 17 are hinged to the carrier disk 12 and the friction disk 4 by means of rivets 18. In the radial protrusions 19 of the annular friction disk 5, rivets 20 can also be mounted. The flat springs 17 are located between the friction disks 4 and 5 with a preload in the direction of the sliding of the friction disks 4 and 5. The relative axial arrangement of both friction discs 4 and 5 is fixed by limiters 21. In the example shown, the limiters 21 are formed by axial elongation of 22 rivets 20, fastening flat strings line 17 with a friction disk 5. The axial extensions 22 pass through the friction disk 4 through the holes 23 formed in it and interact with it through the collar 24. The disk 4 is fixed axially at a distance L, which corresponds to at least half of the axial movement of the push disk 7.
    In the disengaged position, the friction discs 4 and 5 are in the osvo-. waiting position.
    The spring means can be made in the form of coil springs 25 mounted between the two friction discs onto axial extensions 22 of the stops 21. With this design, the flat springs 17 are not required to be made with special prestressing.
    The means limiting the axial displacement of the X friction disks 4 and 5 can also be made in the form of bolts 26, are located in the holes of the annular disk 5 and are screwed into the nuts 27 fixed on the disk 4. The stop made in this way makes it possible to adjust the size of the gaps between the disks. The nut 27 must have self-locking properties.
    Friction clutch has oil cooling. In order to better distribute the cooling oil on the friction disk 4 or the carrier disk 12, an oil catching sheet 28 is attached, having profiled bends 29 and. 30, which should distribute evenly cooling oil over the friction surfaces of the discs. The outer, distal from the axis, part of the bend 30 in the bearing disk 12 is provided with holes 31 for supplying cooling oil to the friction surfaces 4 interacting with the supporting surface 2. Supply of oil for cooling the clutch occurs through the inlet pipe 32, which is connected to the stop device interrupting the flow of oil when disengaging the clutch
    The intermediate plate 6 and the pressure plate 7 are connected by flat springs 33 and 34 to the casing 9. The stop 35 is fixed on the pressure disk 7 and interacts with the intermediate plate 6.
    The flat springs 33 and 34 are located circumferentially in the depressions 36 of the casing 9. The flat springs 33 are pivotally attached on one side by a rivet 37, and on the other side by a rivet 38 to the radial protrusion of the intermediate plate 6. The flat springs 34 are pivotally attached to the casing 9 on one side rivets 39 in the places of attachment of 40 recesses 36, and on the other to the pressure disk 7 by rivets 41.
    The stops 35 are formed in the form of bent plates, which are attached to the pressure disk 7 by rivets 41 connecting the flat springs 34 to the pressure disk 7.
    The stop 35 is in contact with the radial protrusion of the intermediate plate 6 and limits the axial gap Z between the pressure disk 7 and the intermediate plate 6. The gap Z corresponds to the size of the gap X between the friction disks 4 and 5.
    Flat springs 33 and 34 are installed with preload in opposite directions. The flat springs 33 connecting the intermediate plate 6 with the casing 9 act in the direction of the supporting surface 2, and the flat springs 34 connecting the pressure plate 7 with the casing 9 in the direction of the belleville spring.
    The flat springs 34 are given a greater pre-stress, whose flat springs 33, which, when the clutch is engaged, ensure that the pressure disk 7 fits on the cup spring 8 and the intermediate plate 6 to the stops 35, which, in turn, are provided on both sides of the intermediate plate 6 Between the support surface 2 and the friction disk A, as well as between the pressure disk 7 and the friction disk 5, spring plates 42 and 43 are installed, which press the friction disks 4 and 5 from the support surface 2 and the pressure disk 7 in axially direction. The force of the springs 42 and 43 is weaker than the springs interconnecting the friction disks 4 and 5. To disengage the clutch, a sleeve 44 is used, moved by fork 45 towards the disc spring 8. In this case, the outer edge of the spring plate of the spring moves in the direction of the casing 9 Since the flat springs 34 act in the direction of the spring-loaded spring 8, the pressure disk 7 follows the disk-shaped spring 8, followed by which the pressure disk 7 is first moved away from the friction disk 5. After selecting the clearance Z with the help of a retaining abutment 35The blade 6 is retracted from the friction disk 4 and is held at a corresponding distance from it, since the action of force: flat springs 33 is opposite to the action of flat springs 34, however the force of flat springs 33 is much weaker than flat springs 34. Flat springs 33 and 34 provide the discharge of the pressure disk 7 and the intermediate plate 6, while at 1 8 m as the stop 35 provides the specified axial position of the intermediate plate 6 and the gaps on both sides. The friction discs 4 and 5 are moved away from the intermediate plate 6 by the action of the flat springs 17 and are kept in the extended position with a common axial clearance X. At the same time, the friction discs also have gaps on both sides. In addition to the pre-tension of the flat springs, in the event that the flat springs 17 were not installed with a corresponding pre-stressing force, spacer springs 25 may be used. Spring plates 42 and 43, the spring force of which is less than the force developed by the spring 17 or 25, ensure that all the friction surfaces of the friction disks do not adhere to all the friction surfaces of the pressure disk, the intermediate plate and the support surface, as a result of which there is no transmission of right moment. Very little friction between the springs 42 and 43 and the friction discs 4 and 5 can be eliminated with a mounting device that operates between the base 3 and the drive shaft 11. When disengaged, the base 3 moves away from the supporting surface 2 at a distance that corresponds to half the way X or Z.
