    The invention relates to mechanical engineering, in particular to transport engineering, and can be used in the structures of friction clutches of automobiles.
    The aim of the invention is to increase the reliability of operation by changing the stiffness of the elastic elements under the action of the transmitted torque.
    Reliability is achieved by the presence of at least two elastic elements between the case elements of the disk and the hub, one of which is made in the form of a plate with a leg connected to one of the case elements and an elastic console-radius lever, the end of which is made with a shoulder-shaped protrusion. for engaging with a protrusion formed on another body member.

    The shock-absorbing torsion mechanism, mainly for automobile clutch discs, in its present form contains a housing element in the form of a tubular hub I and a housing element in the form of a casing 2, which are connected respectively to the driven and driving shafts (not shown). Between the hub 1 and the casing
    2, inserts 3 are installed. The casing 2 is formed by two plates 4 and 5, which are inserted into each other by edges 6 and 7, connected by welding. On the plate 4, rivets 8 are attached a friction disk 9, and in the edge 6 there are made two pairs of diametrically spaced tabs 10 and 11 in the form of legs ,; cut down and bent into the casing 2 in opposite directions on the circumference.
    The tubular hub 1 is provided with an inner surface of a spline 12 or oval 13 shape for connection with the driven shaft, and on the outer surface with diametrically opposite slits 14 for connection with other elements 15-17.
    The resilient elements in the embodiments of FIG. 7-12 and 15, 17 are co-plates with plates 18 in the form of washers, made with central slots 19, forming a Zimi support surface, and one or two radially protruding legs 20 and 21 in the shape of a trapezium or a spitz-dog 22, as well as with external slits 23 forming one or two elastic cantilever-radius levers 24 and 25 with protrusions 26 at the ends in the form of hooks in the form of hooks oriented outwards.
    Plates 18 can be made with two levers 24 and 25 located on both sides of the leg 20 and the protrusions protrusions 26 in opposite directions from the legs 20, silt with two levers 24 and 25, the directional protrusions 26 in one direction relative to the Spitz 22.
    - To improve elasticity, one or both of the levers 24 and 25 can be made in the form of a spiral. Plates 18 in the form of washers can be made with a central slot 19 in a shape that forms diametrically arranged legs 20 n 21 different views and is cut, and also (to improve elasticity) with triangular holes 27 in the zone between the bases of the levers 24 and 25 and legs 20. The second elastic elements 16 are made in the form of ring springs with ends in the form of legs 28 and hooks 29. Elastic elements 17 are made in the form of plates with legs 30 of trapezoidal shape and with external slots 31 and 32, forming S-shaped elastic cantilever arms 3 radius levers with protrusions 34 equipped with friction elements 35. The mechanism contains four elastic elements 15 in the form of plates 18 of various thickness installed in pairs, two elastic elements 16 in the form of ring springs and two elastic elements 17 in the form of plates with friction elements 35, which installed legs 20, 21, 28 and 30 in the slots of the hub 14 is diametrically opposed to each other, while the hooks 29 of the elastic elements 16 are hooked with the projections 10 and 11 of the casing 2, and the projections 26 made in the form of shoulders on the market. Chaga 24 and 25 of the elastic elements 15 are loosely spaced with respect to the projections 10 and 11 of the casing 2 Cushioning of the torsion mechanism (Mostly for automobile clutch discs works as follows. When the casing 2 is driven in rotation in the direction (Fig. 2.3) , counterclockwise, which corresponds to the operation in the traction mode, first comes into effect one elastic element 16 in the form of an annular spring, and then, when the projections 10 and 11 of the casing 2 come into engagement with the projections 26 of the elastic elements 15 in the form of plates 18 , The forces are added to the forces of the elastic elements 16. At the same time, the friction elements 35 attached to the elastic elements 17, which are sensitive to the influence of centrifugal forces, interact with the edges of the casing 2. When operating in the reverse mode, the angular deviation between the rotating parts is reversed. and there is a process similar to that described, and the other elastic element 16 is loaded into action in the form of an annular spring. In comparison with known devices of similar purpose, prototype and ba By this object, this device has a relatively small stiffness at small values of torque, which ensures good absorption of noise from the dead point to a stop, and on the other hand, it has the ability to increase stiffness with more significant values of torque. In addition, this device is characterized by compactness and ease of installation and disassembly.
