Definitions

  • the invention relates to a coupling, in particular for the mechanical and / or electrical coupling of rail-bound vehicles.
  • Such a coupling with which tensile and compressive forces can be absorbed, is known from German utility model 87 07 485. So that when coupling, starting and braking e.g. Let railroad railcars and / or wagons encounter very large tractive and impact forces and achieve the most noise-free operation possible, this known coupling has energy-absorbing elements, such as ring springs and / or gas-hydraulic, preferably a large energy consumption ensuring double-acting shock absorbers.
  • a difficulty of these couplings which are otherwise excellent in practical operation, is that the coupling and uncoupling requires manual activities outside the vehicle. In addition, uncoupling under high tensile force, for example over 10 tons, is not possible.
  • the invention has for its object to provide a clutch or coupling half, which enables decoupling both at high tensile and compressive forces; Furthermore the coupling should be user-friendly, in particular accessible from above, for example from the bottom of a railway wagon.
  • this object is achieved by at least one, preferably vertical conical bolt connecting the coupling heads of two coupling halves, which advantageously has an inner bore provided with a left-hand thread, into which a screw having a threaded section can preferably be screwed with a threaded pin.
  • a bushing is screwed onto the threaded section and projects with diametrically extending shoulder pieces into corresponding recesses in two receiving blocks.
  • an operator For coupling or uncoupling, an operator only needs a key, for example a ratchet with a certain torque, e.g. 300 Nm on the key head of the screw in the tapered bolt and turn it counterclockwise for coupling or uncoupling.
  • the ratchet or a torque wrench can alternatively be placed captively on the screw head, for example welded there.
  • the shoulder pieces of the socket which is preferably arranged with axial play in the recesses and is advantageously fixed there against rotation by at least one bolt, lie against the recesses bounding surfaces defining above or below. Because of the then fixed position of the bushing, when the screw is turned further, the rotational movements are converted into translatory movements which push the conical bolt either into or out of the bores.
  • the interlocking coupling heads advantageously have chamfers on the front. When coupling, these compensate for any horizontal and / or vertical misalignment, the interlocking surfaces maintaining a slight play to one another which enables decoupling even under high pressure forces.
  • the game is chosen so that in the coupled position only the cone or pins - and not the interlocking surfaces - transmit the compressive and tensile forces; a clearance of approx. 0.1 mm is sufficient for this purpose.
  • swiveling coupling hooks which relieve the conical bolts are arranged on the coupling heads. Due to the interlocking coupling hooks of two coupling halves, the coupling can be separated even with large tractive forces, such as those caused by non-synchronous brakes, particularly in the case of emergency braking.
  • the coupling hooks are each advantageously loaded by a spring.
  • the springs acting on the lever end of the coupling hook facing away from the hook maintain the engagement of the hooks.
  • an adjustment eccentric which can be pivoted against the force of the spring and advantageously has a screw head can be used.
  • a key on the screw head which can be designed as a hexagon, for example, like the head of the taper bolt, and turning the adjustment eccentric of the two coupling hooks, the hooks are pressed apart to decouple the hook connection.
  • the coupling head can be combined with a one-part or two-part electrical coupling arranged on or in the coupling head, which can preferably be connected to a turntable by means of a lever linkage, with the articulation point of a lever of the lever linkage on the by the when the electrical coupling is withdrawn Electric clutch is located distant periphery of the turntable.
  • the lever of the lever linkage which is angled in the retracted position of the electrical coupling or couplings, assumes an extended position if the turntable, which preferably has a screw head, is in accordance with after the key has been placed on it the heads of the tapered bolt and the adjusting eccentric hexagonal screw head is turned.
  • the electric couplings are moved back into their starting position, the levers buckling at their articulation points.
  • At least one compression spring acts on the lever linkage. In this way it can be achieved that the opposite couplings in the extended position of the lever linkage move beyond the ideal center lay against each other and automatically take a middle position, the springs yielding accordingly. Pressing the couplings firmly against one another prevents water, dirt or other contaminants from getting into the coupling and impairing the electrical contacts there.
  • a coupling half 1 e.g. a so-called close coupling, i.e. Coupling half to be connected manually with a second coupling half, or an automatic coupling, is supported with an articulated rod 2 in a bearing 3 which is fastened, for example screwed, to a rail car or wagon (not shown) by means of a flange 4.
  • the coupling half 1 accommodates 5 energy dissipation elements in a housing, such as ring springs and / or gas-hydraulic shock absorbers, and is provided with a coupling head 6 at the end facing away from the bearing 3; this is connected to the housing 5 by half-shell-like sleeves 7 with the interposition of a bellows 8.
  • the bellows 8 automatically adapts to the changes in length caused by tensile or compressive forces on the one hand and on the other hand prevents dirt from penetrating into the tubular housing 5.
  • the coupling head 6 of the coupling half 1 according to FIG. 1 has, in addition to a mechanical coupling part 9, a two-part electrical coupling 10, 11.
  • the electrical couplings 10, 11 are articulated on the coupling head 6 by means of a multi-lever linkage 12, 13, 14, 15.
  • a spring 16 acts on the lever 14 of the lever 13, 14 forming a knee joint in the inoperative position of the couplings 10, 11 shown in FIG. 2.
  • the levers 15 are at the periphery with their ends remote from the couplings 10, 11 a turntable 17 articulated at points 18, 19.
  • the turntable has a hexagonal screw head 20 and can be swiveled through 180 ° by means of a key placed on the screw head 20 or a ratchet.
  • the mechanical coupling part 9 of the coupling head 6, shown in detail in FIGS. 4 and 5, consists of two plates 26, 27, which project parallel and one above the other at a distance, projecting in the coupling direction 22 via the central layer 21, and a plate set back, in alignment with the clearance between the Plates 26, 27 extending locking plate 28.
  • the top and bottom plates 26, 27 and the locking plate 28 are with themselves from above provided through tapered through holes 29.
  • the plates 26, 27, 28 have insertion bevels 30.
  • a conical bolt 31 inserted from above through the bores 29 of the plates 26 to 28 secures the coupling assembly.
  • the coupling assembly can also be achieved if, instead of the locking plate 28, an eyebolt 55 of the opposite coupling half, shown alternatively in FIG. 5, which, for example, can also be only a rigid tube, engages between the plates 26, 27.
  • the conical bolt 31 has an inner bore 32 with a left-hand thread 33 in its upper end face, ie the larger diameter in the installation direction, into which the threaded pin 34 of a screw 35 is screwed.
  • a bushing 38 is screwed onto a threaded section 36 of the screw 35, approximately in the middle between the pin 34 and a hexagonal screw head 37 of the screw 35, which engages with recesses 40 with diametrical shoulder pieces 39.
  • the recesses 40 are arranged in two receiving blocks 41, which are opposite each other at a distance and are fastened on the upper plate 26.
  • the screw 35 together with the tapered pin 31 and the bush 38 is in alignment when inserting the tapered pin 31 into the one above the other lying holes 29 of the plates 26, 27 and 28 or the eyebolt 31 first inserted between the receiving blocks 41.
  • the bushing 38 with the flattened outer surfaces of the shoulder pieces 39, assumes a position parallel to the receiving blocks 41 and is then brought into the position shown in FIG. 4 by rotating through 90 °, in which the shoulder pieces 39 engage in the recesses 40.
  • the screw 35 is turned clockwise, the conical bolt 31 is moved further and further downwards, ie in the direction of the cone.
  • the position of the bush 38 is secured by a bolt 43 which is captively attached to a chain 42 on the mounting block 4l;
  • the bolt 43 is inserted through bores 44, 45 of the holding block 41 or of the shoulder piece 39.
  • the screw 35 is turned counterclockwise and the tapered pin 31 is moved upwards out of the holes 29 in the plates 26, 27, 28.
