    This invention relates to an automatic coupling for rail vehicles.
    The purpose of the invention is to increase reliability.
    Fig. 1 shows a coupler that is in a state of readiness for connection, a section; Figure 2 is the same in the process of connecting the two clutch heads; on fig.Z - the same, both halves of the coupler are connected and locked; 4, in the unlocked and disconnected positions, with the couplings still not disengaged; 5 is the same, the coupler heads are partially out of engagement.
    Coupling head consists of front 1 and rear 2 tail parts. In the front part 1 of the head there is a pull pin 3 and a clamp 4 for the pin. The trailing finger 3 contains a conical head 5, an annular groove 6 with a face-shaped clamping surface 7 and two cylindrical centering elements 8.
    The clamp 4 comprises a wear-resistant centering ring 9 located in the front part 1 of the head and a receiving part 10 which is rigidly connected to it. At the receiving part 10 on two fingers 11, with the possibility of swinging, one locking lever 12 is fastened, the protrusion-shaped locking elements 13 of which can be inserted through the holes 14 of the receiving part 10 into its inner space 15. In the front part 1 of the automatic coupler head covers the receiving part 10 with locking levers 12 and is mounted for movement in the direction of the longitudinal axis 17. The frame 16 contains a contour 18 that interacts with the locking levers 12 An insertion rod 20 is inserted through the opening of the yoke 19, the push rod 20, one end 21 of which extends in the opening 22 of the receiving part 10 to its internal space 15, and the other end 23 is guided into. blind hole 24 of the tail element 2.
    On the push rod 20, adjacent to the protruding surface, is a gripper 25, which contains two radially opposite nozzles 26. A compression spring 27 is located between the gripper 25 and the tail element 2, which pushes the gripper 25 in the direction of the protruding surface of the push rod 20. both sides of the push rod 20 are reinforced with guide rods 28, the free end of which is guided into the blind holes 29 of the tail element 2 and on which the compression springs 30 are located resting on the tail element 2 and the grass rsu 19.
    A retainer 32 is located on the yoke 19 with the possibility of swinging around the finger 31, which, above and below the yoke 19 or the push rod 20, contains a lever arm 33 with a notch 34 and an abutting surface 35. Between the yoke 19 and the locking 32, stretching springs 36 are located above and below which squeeze the retainer 32 in the direction of the gripper 25, so that their pins 26 are held in the recesses 34. The locking lever 12 contains in the attachment area on the finger 11 a pressure cam 37 with a surface 38 of abutment. In order to displace the frame 16 against the pressure of the springs 39, two guide pins 40 are fastened to the frame. In the tail element 2 there is an unlocking bar 41 with a shoulder 42. The bar 41 interacts with the actuating part 43.
    To seal the hole 14, the lever 12 encloses the seal 44, which prevents the head element from entering the inner space. Instead of a power magnet 4, a pneumatic cylinder operated by means of a magnetic valve or an electric motor with a reduction gear can also be used, for example. Located on the side of the push rod 20 in the tail element, the actuating part 43 is driven by the pull rod and rod mechanism. Swinging movement of the Executive part 43 passes preferably transversely to the longitudinal axis 17.
    The ratio of the lever on the retainer 32 relative to the point of impact of the unlocking rod 41 and the executive part 43 to the fit of the nozzles 26 in the recess 34 is preferably in the case L; l 5: 1.
    Fig. 1 shows an automatic coupler head in a state ready for connection, with the spring 19 of the yoke 19 being pressed to the pressing cams 37 of the locking levers 12 so that they are in the inserted position with the seal against the receiving part 10. The frame 16 and the push rod 20 located in the clamping direction for the traction pin in the final position, which is also provided by compression springs 30 or compression springs 27.
    When connecting the coupler (Figures 1 and 2), both coupler heads are automatically aligned due to the shape of the head, pull fingers and sonic notch in the head member 1 when clamping 4 for the pull pin, with the result that the pull fingers 3 of the same coupler can
    enter the clamp 4 for the pull fingers of the other coupling head.
    Upon further alignment of the couplers, the locking levers 12, due to the conical shape of the finger head, rotate outwardly until they are adjacent to the cylindrical part of the head 5 of the finger. At the same time, the yoke 19 under the influence of the pressure cams 37 of the locking levers 12 is retracted a short distance, and the springs 27 and 30 of compression are also compressed and carries away the frame 16 with the force of the preload tension of the springs 39 of compression.
    Upon further insertion, the head 5 of the finger interacts with the push rod 21 end located on the front side and squeezes it back, while the traverse 19 is displaced through the nozzles 26 of the gripper 25 and the clamp 22 located on the traverse 19. Formed by springs 27 and 30 compressing the spring the drive undergoes further tension. The yoke 19 carries the frame 16 through the springs 39 until it is held by the locking levers 12 on its beveled portion 18a of the contours 18 of the abutment.
    Due to further reduction (Fig. 2), the yoke is pushed back by the action of the thrust pin 3, the push rod 20, the gripping nozzles 26 and the notches 34 of the clamp 32, and the spring drive formed by the springs 27 and 30 is further tensioned. the compressions are compressed by the backward-moving cross member 19 and blocked by the locking levers 12 and the frame 16. With further insertion of the hitch, the spring drive formed by the compression springs 27 and 30 is further tensioned, as well as the compression springs 39, until contact of the impact surfaces of the head elements 1 will be achieved.
    A few millimeters before the collision of the impact surfaces of the coupling elements 1 are precisely aligned or centered under the influence of the centering element 8 of the trailing finger 3 and the centering ring 9. When both impact surfaces of the head elements 1 are connected, the further advancement of the traction finger 3 stops (Fig. 3) . The pull pin 3 displaces the yoke 19 through the push rod 20, the gripper 25 and the latch 32 into its rearmost position so that a complex compression occurs between the springs of the spring drive formed by the springs 27 and 30. By releasing the displaced head 5 of the finger of the trailing finger 3, the locking elements 13 of the locking levers 12 rotate from the frame 16 into the annular groove 6 tons of the finger 3.
    The rotation is carried out due to the displacement of the frame 16 under the influence of the tensioned springs 39, and the inclined part 18a of the contour 18 of the abutment presses the locking levers 12 inward. Now the coupler is locked due to the tight fit of the locking levers 12 with the locking element 13 to the end-shaped surface of 7 tons of the pivot pin 3, and
    5, the locking lever is blocked by adhering to the straight loop 18 in the frame 16 (FIG. 2). The ratio of the lever on the locking lever 12 is H: h 3: 1.
    Figure 4 shows the automatic coupling in the unlocked and disconnected position, with the couplers not yet shredded one after the other. For the purpose of disconnection, the release is carried out either by the train driver using remote control by turning on the power magnet 45 or the pneumatic cylinder or by manually actuating the actuator 43. In one case, the release bar 42 is pressed, and in the other case the actuator 43 with manual actuation against the stop surface 35 of the latch 32, wherein the latch 32 is tilted
    5 and its release from engagement with the gripping nozzles 26. Due to this, the connection between the crosshead 19 and the push rod 20 is disconnected, and the crosshead 19 together with the frame 16 is pre-displaced under
    0 by the action of the compression springs 30 until the traverse resists the stop surfaces of the locking levers 12. The latter are unlocked, as they can now be rotated by means of the locking of the contour 18.
    When separating the coupler heads (Fig. 5), the locking levers are rotated, and their pressure cams 37 slightly displace the yoke 19 back into
    0 against the pressure of the springs 30. If the trailing pin 3 is outside the area of the locking levers 12, the latter are pressed again under the pressure of the springs 30 through the yoke 19 onto the pressure jaws 37
    5 in the direction of the seals 44. When the thrust finger 3 is extended, the pressure rod 20 under the force of the compression spring 27 and the gripper 25 also moves up to the stop of the gripper 25 in the yoke 19. Under the action of the extension springs 36, the retainer 32 grips its
    the recess 34 of the nozzle 26 of the gripper 25, as a result of which the common mechanism is automatically automatically transferred to the Ready for connection position (Fig. 1).
    The proposed design and principle of operation of the locking mechanism when a small force is applied provides the possibility of disconnection under conditions of influence of substantial tractive force, which is possible with the help of a correspondingly small and inexpensive power magnet.
