    Clutch mechanisms are disclosed having two clutch assemblies associated with a single or two separate output shafts. To minimize the axial dimension of the clutch mechanism and yet provide the required spring loading when the clutch assemblies act independently, for example, the spring loading is provided by two Belleville type spring washers interposed between the pressure plates of the clutch assemblies. The spring washers are arranged axially and their configurations tends to converge in the same direction. Spacer ring members are interposed between the spring washers at both their inner and outer peripheries and between each of the spring washers and the pressure plate facing it so that the spring washers are borne exclusively by the spacer ring members.

    This invention relates to mechanical engineering, in particular to friction clutches.
    The known free-ion clutch contains two clutch units, each of which includes a bearing disk connected to the drive shaft, a friction disk mounted on the driven shaft, a pressure disk mounted with axial displacement, and elastic elements placed between the pressure discs and pushing the friction disc to the reference CL.
    In order to reduce the axial dimensions and increase the load capacity, in a friction clutch containing two clutch units, each of which includes a bearing disc connected to the drive shaft 11M 20, a friction disc mounted on the driven shaft, a pressure disc mounted with axial movement, as well as elastic elements placed between the pressure 25 disks and below the friction disk to the support disk; elastic elements are made in the form of at least two disk springs axially oriented in one Nom direction and AOR
    separated by spacer rings, one of which is located in the area of the outer diameter of the disc spring, and the other in the area of its internal diameter, with ring gaskets being installed between the disc springs and each pressure disc.

    The clutch contains two clutch units 1 and 2 located coaxially one after the other. Each of the blocks comprises support disks 3 and 4, friction disks 5 and 6, associated with hubs 7 and 8 and axially movable with respect to the support disks. The pressure discs 9 and 10 are connected during rotation with the support disks 3 and 4 and are movable with respect to them for clamping the respective friction disks 5 and 6. The support disk 3 can be made in the form of a flywheel and is connected during rotation to the drive shaft, and each of hubs 7 and 8 friction disco
    5 and 6 may be associated with a driven shaft, for which grooves are provided on the inner surface of the hubs. Since this clutch has two outlets, each of the friction discs is mounted on a separate shaft.
    The supporting disk 4 has an annular protrusion 11 in the peripheral part, closing the friction and pressure disks and in contact with the disk 3. The supporting disks 3 and 4 are connected with screws (not shown in the figures) passing into the hole 12. The lateral surface of the annular protrusion 11 is made grooves l3, in which the protrusions 14 and 15 of the pressure disks 9 and 10 are arranged with an axial clearance, ensuring engagement with the rotation of the pressure disks with the supporting disks 3 and 4 and the tolerance axial movement of the pressure disks with respect to the supporting disks.
    Between the pressure discs 9 and 10, located against each other, there are elastic elements acting on the disks 9 and 10 in the direction
    clutch positions, i.e. clamping the friction discs 5 and 6 between the pressure and support discs.
    The elastic elements are made in the form of two Belleville springs 16 and 17, axially oriented in one direction and separated one from the other: by spacer rings 18 and 19, located in the zone of the inner diameter of the disc springs, and rings 20 and 21, located in the zone
    their outer diameter. The disc springs are located between the pressure disk 9, on which the spring 16 with the ring 20 / and the pressure disk 10 rests on the outer section, on which the spring 17 with the ring 19 relies on the internal section. Thus, each spring 16 and 17 contact only the rings as for mutual cross-linking and for interacting with pressure discs 9 and 10, which makes it possible to reduce the friction during uncoupling, and hence the firing force. To accommodate the disc springs 16 and 17, annular grooves 22 and 23 are provided on the pressure discs 9 and 10. Disc springs can be made in the form of an annular section 24 and radial projections 25.
    Disengaging levers 26 are attached to clutch unit 1. Each of them is mounted on axle 27 passing through protrusions 28 on supporting disc 4. At the free end most distal from the block axis, uncoupling levers 26 are attached to pressure plate 9 using t g 29 , pivotally attached at point 30 to the release levers 26 and passing with clearance through the supporting disc 4, the pressure discs 10 and 9. On the stops are mounted the stops 31.
    Springs 32 are mounted around each of the ribs 29 between the supporting disk 4 and the corresponding release lever 26. The clutch block 2 also includes the release levers 33, mounted on the axis 34, mounted in the projections 28. The levers 33 are located radially and have stops 35, through which they come into contact with the intermediate levers 36, which are mounted on the axis 37, mounted in the projections 28.
    At the free end of the lever 36, you have a stop 38 through which the OI contacts the stop 35 on the lever 33. A push rod 39 with a thread 40 and a lock nut 41 passes through the pressure disk 10. The springs 42 are mounted between the release levers 33 and the support disk 4.
    When moving the release lever 26 in the direction of the left arrow (Fig. 3), force 29 is applied to the axle disk 9, which is then removed from the support disk 3 towards the disc springs 16 and 17. The friction disk 5 is released, and the corresponding The driven shaft is no longer associated with rotation with the drive shaft on which the supporting disk 3 is mounted. When the action on the release levers 26 stops, the springs 16 and 17 reapply the friction disk 5, and the springs 32 return the levers 26 to their original position.
    Similarly, when the release lever 33 is moved against the h & arrow (Fig. 3), the intermediate lever 36 rotates and the pressure disk 10 retracts through the pushers 39, releasing the friction disk 6, the corresponding driven shaft is no longer connected to the drive shaft, on which is mounted, bearing disc 3.
    When the action on the release levers 33 ceases, the springs 16 and 17 again clamp the friction disc into the disk 6 and return the intermediate levers to their original position. 36, and the springs 42 return to their original position.
    Spacers placed between the cup springs can have cross sections of various diameters, and the cup springs themselves may have different characteristics.
