    专利说明:

    The invention relates to mechanical engineering, in particular to devices for transmitting rotation,
    The aim of the invention is to increase the reliability of operation by compensating for changes in the compressive force of the friction surfaces as a result of their wear.
    FIG. 1 shows a frictional 1-clutch, partial section; FIG. 2 — view A in FIG. 1, in FIG. 3 - a triangle of forces resulting from the action of elastic plates; FIG. 4 is a diagram of the effect of forces on friction surfaces
    The friction clutch includes a housing 1, a pressure disk 2 located therein, a diaphragm spring 3 and a friction disk 4. The housing 1 is fixed with screws 5 on the flywheel 6 of an internal combustion engine. The pressure disk 2 is connected to the clutch housing 1 with elastic plates 7, In this case, there are three elastic plates, but if necessary, their number may increase. The plates 7 are fixed on the clutch housing 1 and on the pressure disk 2 with the possibility of rotation around the axis 8,
    The clutch rotates in the direction indicated by the arrow, while the clutch body 1 carries the pressure disk 2 with the aid of elastic plates 7,
    The ends of the elastic plates 7 are fixed on the surface 9 of the clutch housing 1 and on the surface 10 of the pressure disc 2 in planes parallel to the surface of the pressure disc 2. Considering that the end of the elastic plate 7 fixed on the pressure disc 2 is at a greater distance from the surface of the flywheel 6, than the end fixed on the housing 1 on the elastic plates 7, two bends are made. The area between the two points of its clamping angle with the surface of the pressure plate 2 is o4. The clamping points are those points of the elastic plate 7 between which its deformation is not limited. When the flywheel 6 rotates and together with the housing 1, there is a tangential moment ti FIG. 3) creates in the elastic plates 7 a force FP in the direction of the elastic plate 7. This force creates on the pressure disk 2 a vertically directed to the max

    Vick 6 Force Rd. Force F increases with silt FP diaphragm spring 3,
    Due to the wear of the friction elements, t, e, of the pressure disk 2, i of the flywheel 6 and the friction disk A, the angle oi between the elastic plate 7 and the surface of the pressure disk 2 is reduced. This angle is in the normal clutch 2.5-3. In order to have a positive effect also when worn friction elements, it is advisable to choose a larger value,
    When the angle oi is 5 greater than the angular deviation, arising due to the wear of the friction elements and when calculating with a friction coefficient of 0.3, the force Fg gives an increase in the transmitted torque of several percent. When the angle about is chosen to be 15 greater, this increase may be 15
    20%, With a value less than 5, there is no tangible result.
    When an increase in torque is not necessary, a proportionally weaker diaphragm spring 3 may be applied in the same clutch. In this case, the load of the diverter (not shown) becomes less
    By means of an appropriate dimensioning, the ability to transfer the clutch during the entire service life of the friction disk 4 can be maintained substantially at the same level and the characteristic of force and moment is much more stable. The design tools required for this are simple and cheap, they do not require substantial changes in the normal performance of the clutches with the diaphragm springs.
    In diagram 4, the displacement of the pressure disk 2 arising due to the wear of the friction disks 4 is applied on the abscissa, and the force of the diaphragm spring 3, respectively, the elastic force of the plate 7, is applied along the ordinate. that the resultant characteristic remains largely constant over the entire life cycle.
    In addition to the forces described above, the elastic plates 7 are also affected by a force in their own plane.

    This force arises due to the fact that during operation the pressure plate 2 heats up more than the body 1 and its dimensions change to a greater degree, therefore the ends of the elastic paper 7 move in the radial direction differently. In connection with this, the plates 7 would be bent in their own plane if they were rigidly fixed on the pressure disk 2 or on the housing 1. Such a load is undesirable. Therefore, it is advisable to fasten the elastic plates 7 using such axes 8, which allow their rotation.
