    The friction means acting between the two rotary parts constituting a torsion-damping device comprises at least one annular component which is engaged by means of an axial bearing surface with an axial bearing surface of one of the rotary parts and which, by engagement means, is capable of being connected in rotation to the one rotary part over at least one range of the angular movement between the rotary parts. According to the invention, the annular component is opened circularly by means of at least one slit, and elastic means are associated with it which permanently stress it radially in the direction of the axial bearing surface of the one rotary part.

    The invention relates to mechanical engineering, in particular to torsional damping devices for friction clutches.
    The purpose of the invention is to improve performance.
    FIG. 1 shows a torsional damper device for friction clutch, front view; in fig. 2 shows section A-A in FIG. one; in fig. 3-11 are frontal embodiments; in fig. 12 is a view B in FIG. eleven; in fig. 13, 14 - section A-A in FIG. 1, embodiments.
    A torsional damping device for friction clutch, containing two coaxial parts (leading and driven, respectively) mounted rotatably one relative to the other within a given angular deviation, and
    also placed around the circumference between the said parts are elastic means, one part of which is made in the form of springs 1 and 2.
    The driven portion comprises a hub 3 and a disc 4 mounted thereon. The hub 3 is mounted on the driven shaft (not shown) by means of the splines 5.
    The leading part contains two guide rings 6 located at some distance from both end sides 7 of the disk 4. Between the rings 6 are connected axially mounted with a gap in the recesses 8 located along the periphery of the disk 4, with spacers 9. In addition, the leading part contains a friction disk 10 with friction linings 11 connected to guide rings 6 in the middle

    s
    strut 9. The friction disk 10 is adjacent to one of the guide rings 6. Between the friction disk 10 and the hub 3 there is a monoblock ring part 12, forming a bearing with the rim 13 and contacting one of its axial bearing surfaces 14 with one part and the other sides - another axial bearing surface 15c with the second part. The elastic means of circumferential action, located between the leading and the driven parts of the device, are formed by the said cylindrical helical springs 1, 2, some of which are made with lower rigidity than the others. Windows 16, 17 are made in the disk 4 of the driven part, and windows 18, 19 are in the guide rings 6 and the friction disk 10 of the leading part.
    The said lower stiffness springs 1 are located with contact with the edges of the windows 16, 18 of the two parts in their neutral position, and the springs 2 of greater rigidity are located with contact with the edges of the windows 19 of one part, i.e. driven, since the circumferential extent of windows 17 of disk 4 exceeds the circumferential extent of windows
    19 guide rings 6. In the initial position, there is a gap between each end of the springs 2 and the edges of the windows 17 of the disk 4.
    The second part of the elastic means is made in the form of a dry friction damper, which on the one hand is made in the form of the aforementioned ring part 12 with the rim 13, and on the other hand - in the form of a ring part
    20radial friction. This part 20 is connected by means of engagement 21 with one of said coaxial parts rotatably at least within a certain angular deviation and is in contact with another part. One of the said ring parts 20 is made with a slot 22 located between the outer and inner side peripheral surfaces 23 with the possibility of radial compression and dividing said ring member 20 into two sectors 24. At the same time, the torsional damper device is provided with radially in the direction of said axial bearing surface 14 or 15 onto said annular part 20 with the possibility of reducing its slot 22.
    Ring part 20 can be made in one piece with additional elastic means 25.
    The additional resilient means 25 can be made as a separate resilient element interacting with said part.
    The elastic element 25 can be installed with the possibility of interaction with the edges 26 of the ring part 20, limiting its slot 22.
    The elastic element 25 may be made in the form of an annular part 27 coaxial with the device.
    The elastic element 25 can be made in the form of a harness covering the ring part 20.
    The edges 26 of the ring part 20, bounding the slot 22, are circumferentially spaced from one another. The edges 26 of the ring part 20, the mixing slots 22, may be overlapped.
    The engagement means 21 may be located diametrically opposed to the slit 22 on the ring part 20.
    0 The engagement means 21 may be located on the ring part 20 in several of its zones evenly distributed around the circumference around the device axis,
    5 The engagement means 21 may be located on the annular part 20 in one zone, placed outside the zone of the diametrically opposite slot 22,
    The engagement means 21 can be executed as a plug-in element 28, made in one piece with the said ring part 20, and as an additional plug-in element 29 interacting with it, connected to one of the
    5 coaxial portions, wherein said insertion elements 28, 29 are arranged with a circumferential gap between them.
    The springs 2 of greater rigidity are diametrically opposed located at about 17,19, with one part of these springs 2 installed with a gap in the windows 17 larger than the second part.
    Between the driving and driven parts, various other
    5 means of training.
    The device works as follows.
    When transmitting torque, the flanges (not shown) compress the friction
    0 disk 10. In the first stage, the torque is transmitted from the driver to the driven part by means of springs 1 of lesser rigidity. At the second stage, due to the deformation of the said springs 1, a smaller distance of 5 eors is chosen between one part of the springs 2 of greater rigidity and they come into operation. At the third stage, a larger gap is selected and the second part of the springs 2 comes into operation, after which the torque is transmitted through all groups of springs 1,2.
    At all stages, the ring parts 12, 20 create an additional moment of friction between the master and the driven parts, and due to the rotation and depending on its direction, one of the sectors 24, carried along by this rotation, tends to press against the hub 3 and the second sector 24 is pressed . In the event that the sector 24, which presses against the hub 3, is of greater length, then at a given direction of rotation, the ring part 20 creates a greater moment of friction than when rotated in the opposite direction.
