Definitions

  • a shunting coupling is understood here to mean a coupling with which the locomotive driver couples the locomotive and the wagons from his cabin, in other words, the locomotive is quickly and easily coupled to the train unit during the shunting work and uncoupled from the train unit.
  • a line clutch is to be understood here as a clutch which is similar to the clutch mentioned above but also fits line service.
  • pulling hooks and so-called screw couplings are used as couplings between the wagons as well as between the locomotive and the wagons in the countries belonging to UIC.
  • the cars and locomotives are equipped with side buffers.
  • the coupling element used between the cars and the locomotive and between the various cars is the so-called central buffer, which always couples itself automatically when the cars are pressed together.
  • the wagons equipped with the central buffers have no side buffers.
  • the wagons fitted with towing hooks cannot easily be coupled together with the wagons provided with central buffers.
  • the design of the interchangeable coupling according to Patent No. FI 78031 represents an improvement of the design according to Patent No. FI 41039 (DE-A-1 605 210), in which e.g. the transition bridge of the passenger carriage prevents the pulling bracket from being coupled to the pulling hook from above.
  • This invention relates to such a supplement to the above-mentioned shunting couplings, the so-called VAPITI couplings, that they can also be used as line couplings for pulling express trains.
  • the structure according to patent no. FI 78031 or FI 41039 is best suited for shunting and it cannot necessarily be used when pulling passenger or freight trains on scheduled services, because it has been thought possible that the pulling bracket can go through could loosen the influence of quick jerks or inertial forces from the hook.
  • the improvement according to the invention ensures that fast jerks and inertial forces, e.g. when pulling an express train, will not cause the coupling bracket to loosen from the pull hook of the train.
  • FIG. 1 represents the various functional positions of the line clutch
  • FIG. 2 illustrates the function of the locking bolt of the clutch according to the invention.
  • lever 3 shows the following positions of a lever 3: a) driving position, b) coupling position, c) uncoupling position and d) vertical position.
  • the locomotive is in turn uncoupled from the car in that the driver, who is in the driver's cab, raises the lever 3 into position c by means of the working cylinder 8 by actuating a pressure valve, the front part of the bracket 5 detaching from the pulling hook and the locomotive can thus be driven backwards and away from the car.
  • the coupling on the pull hook is secured by such flexible pressing of the bracket 5 on the pull hook that in the event that the distance between the train and the locomotive suddenly becomes smaller or the train and the locomotive e.g. jump on the switch, the bracket and the lever 3 are immediately stretched into position a, the fit of the coupling being maintained.
  • the function according to the invention thus gives the bracket 5 and the lever 3 a flexible function, so that when the locomotive pulls, they are able to stretch and the coupling can withdraw immediately when the tractive force is reduced.
  • Such a function can be achieved, for example, by a spring or by the hydraulics provided with pressure accumulators or by using a compressed air cylinder as the working cylinder of the lever 3, it being possible for the invention to implement the function by means of the elastic properties of the compressed air.
  • the force required for this due to the weights of the coupling parts 3 and 5 to counteract jerk and inertial forces is approximately 7 kN.
  • FIG. 2 the locking bar 10 is shown enlarged for better clarity with respect to FIG. 1.
  • the piston rod 11 of the working cylinder 8 is coupled to the lever 3 in FIG. 2 by a lever spindle 12.
  • the locking bolt 10 is connected by a bolt 17 to the lever spindle.
  • the lower position of the lever 3 in relation to the lever spindle is adjusted by a screw 13.
  • the lever 3 has a small margin between a cam 16 of the locking bar and the adjusting screw 13. In the travel position (a), the cam 16 presses the lever down, the bracket 5 remaining pressed on the pull hook.
  • the locking bar 10 is turned to the "open” position, the cam 16 of the lever rotating out of the way of the lever.
  • the locking bar can have a tubular extension 18, on which e.g. the locking pin (d) of the lever can be placed in the vertical position. This pin holds the locking bar in the "open” position when the lever 3 is lifted by hand on the locking fork.
  • the solution according to the invention guarantees that, for example, rapid jerks and inertial forces which occur when the fast train is being pulled are not able to cause the bracket 5 to be released from the pull hook.
  • the invention also reduces jolts and bumps between the locomotive and the wagon, and thus also movement movements with respect to other cars.
  • the coupling according to the invention enables the coupling of a locomotive to a car equipped with a pull hook but also to a car equipped with a central buffer, because the lever which is coupled to the pull hook is mounted on the central buffer of the locomotive.
  • the devices of these couplings include an electrical control system, the control push button housing of which is placed in the driver's cabin of the locomotive.
