    专利说明:

    The invention relates to mechanical engineering and can be used in disc friction clutches, in particular vehicles, with one or two discs and diaphragm springs.
    The purpose of the invention is to increase the reliability of operation by increasing the synchronism of removal of friction discs.
    Figure 1 shows the disk friction clutch in the plan; figure 2 - friction clutch in single-disk performance, side view; on fig.Z - friction clutch in a double-disc version, side view.
    The friction clutch disc, in particular, for vehicles includes a housing 1, on which three eyelets 2 are made at equal central angles of 120 °. A pressure plate 3 is attached to the eyelet 2 by means of three flat springs attached to its eyelets 4. Springs 5 are attached to eyelets 2 and 4 by means of rivets 6. A pressure element in the form of a diaphragm spring 7 contacts the surface of the pressure plate 3. The connecting elements made of iron are riveted to the pressure plate 3 together with flat springs 5 e tacks 8, adjacent to the membrane spring 7 and pressing it to the pressure plate 3. The friction disk 9 is placed between the flywheel 10 and the pressure plate 3.
    The double-disk clutch (fig.Z and 1) is composed using parts of the previously presented single-plate clutch.
    On the lugs 2 provided on the coupling body 1, a pressure plate 3 is attached by means of flat springs 5, and an additional pressure plate 11 is fixed by means of flat springs 12. The flat springs 5 and 12 are arranged on both sides of the eyes 2 and attached by rivets 6.
    The design of the pressure plate 3 removed from the flywheel 10 and the membrane spring 7 is as described. On the pressure plate 11 adjacent to the flywheel 10, the lugs 13 are provided and the other end of the flat spring 12 is attached to them using rivets 14. The flat spring 12 is shorter than the flat spring 5, but can be made the same by changing the layout.
    . In the pressure plate 3 on the eyelet 4 and in the housing 1, opposite holes are made for placing the ball ends of the two-arm lever 15c to be rotatable. In the intermediate point of application of force in the middle part
    The lever 15 is parallel to the axis of adhesion, a hole is made in which the connecting element 16 in the form of a rod is arranged with a gap. Central angles formed by the same points of the adjacent two shoulders 15, are equal to each other.
    Between the pressure plate 11 and the flywheel 10 is placed the second friction disk 17. One of the ends of the connecting
    0 of the element 16 is fixed in the eyelet 13 provided on the pressure plate 11, while at its other end on the opposite side of the pressure plate 11 the side of the two shoulders lever 15 is fixed to the stop 18. Consisting of the double shoulders lever 15 and
    5 of the connecting element 1b, the mechanism can be performed as follows. that one end of the connecting element 16 is attached to the two arms of the lever 15, and the other end of it is attached to the pressure plate 11 by means of a friction connection (not shown) which, when reaching the axial superior force, allows the end of the connecting element 16 to move relative to the pressure plate 11 for
    5 compensate for the effect caused by the possible uneven wear of the friction discs 9 and the amount of decoupling.
    Odnodiskovo.e clutch works as follows,
    In the closed state, the diaphragm spring 7, through the pressure plate 3, presses the friction disk 9 to the flywheel 10. When the clutch opens, i.e. tap him
    5 by means of pressure on the middle of the diaphragm spring, its flange moves away from the flywheel 10 and with the help of claws 8 it captures with itself a pressure plate 3, as a result, the friction is released
    0 disk 9 and there is a departure.
    Dual clutch works as follows.
    In the closed state of adhesion, the diaphragm spring 7, through the pressure plate 3, presses the friction disk 9 to one of the sides of the pressure plate 11 and through the friction disk 17 using the other side of the pressure plate 11 to the flywheel 10. Thus,
    0, torque transmissions accept both friction disks 0 and 17.
    When uncoupling, the diaphragm spring 7 using clamps 8 removes the pressure plate 3 from the flywheel 10, while
    5, the first engages a double-arm lever 15. The double-armed lever 15 removes the pressure plate 11 simultaneously by means of the connecting element 16.
    the clamping plate 3 from the flywheel 10, resulting in a simultaneous disengagement of both pressure plates 3 and 11. The connecting element 16 provides a drain, i.e. lift, the pressure plate 11 and its approach to the flywheel 10 together with the friction disk 9 by means of a two-arm lever 16.
