Definitions

  • the invention relates to an automatic clutch for rail vehicles, as characterized in the preamble of claim 1.
  • the object of the present invention is to create an automatic clutch of the type mentioned at the outset, in which a disengagement under a large amount of tensile force is possible with a small amount of force, with disengagement of the clutch being completely excluded in the engaged state.
  • Fig. 1 shows in cross section one of the two coupling heads of the same type, on the head piece 1 a draw bolt 3 and a draw pin receptacle 4 is arranged.
  • the tension bolt 3 has a tapered bolt head 5, a recess 6 with an end-shaped clamping surface 7 and two cylindrical centering parts 8.
  • the draw bolt receptacle 4 has a wear-resistant centering ring 9 arranged in the head piece 1 and a receiving part 10 which is fixedly connected to the head piece 1.
  • a locking lever 12 is pivotally mounted on two bolts 11, the nose-shaped closing part 13 of which can be pivoted through openings 14 of the receiving part 10 into the interior 15 thereof.
  • the locking lever 12 has a pressure cam 37 with a contact surface 38 in the region of the bearing on the bolt 11.
  • the openings 14 are sealed by the closing lever 12 resting on seals 44 so that no contaminants can get into the interior of the coupling piece 1 from the draw bolt receptacle 4.
  • a frame 16 is mounted displaceably in the direction of the longitudinal axis 17 of the draw bolt receptacle 4 or the draw bolt 3 of the second coupling head and surrounds the receiving part 10 with the locking levers 12.
  • the frame 16 each has a contact contour 18 which interacts with the locking levers 12.
  • Two guide bolts 40 are fastened to the frame 16, on which a cross member 19 is mounted so as to be displaceable relative to the frame 16 against the pressure of springs 39.
  • a push rod 20 Coaxial to the longitudinal axis 17 is a push rod 20 which is inserted through a bore in the cross member 19, one end 21 of which sticks in a bore 22 of the receiving part 10 and extends into its interior 15 and the other end 23 in a blind hole 24 of the rear piece 2 is led.
  • guide rods 28 are fastened on both sides of the push rod, the free end of which are guided in blind holes 29 of the rear piece 2 and on which compression springs 30 are arranged on the rear piece 2 and on the crossbar 19.
  • a bolt 32 is arranged on the cross member 19 so as to be pivotable about the bolt 31 and has a lever arm 33 above and below the cross member 19 and the push rod 20, each with a recess 34 and a stop surface 35. Between the cross member 19 and the bolt 32 tension springs 36 are arranged above and below, which press the bolt 32 against the driver 25, so that their tops 26 are held in the recesses 34.
  • a lifting magnet 45 is arranged in the rear piece 2, to which an unlocking rod 41 is provided, which is provided with a collar 42 forming a stop surface, the direction of movement of which extends preferably transversely to the longitudinal axis 17.
  • Solenoid valves controllable compressed air cylinders or an electric motor with reduction gear can be used.
  • An active part 43 is arranged in the rear part 2 to the side of the push rod 20 and is actuated by a linkage (not shown). The pivoting movement of the active part 43 preferably runs transversely to the longitudinal axis 17.
  • Fig. 1 shows the coupling head in the ready-to-couple state, wherein the crossbar 19 is pressed against the pressure cams 37 of the locking lever 12 by the pressure of the springs 30, so that they bear sealingly against the receiving part 10 in the pivoted-in position.
  • the frame 16 and the push rod 20 are in the direction of the draw bolt receptacle in the end position, which is also brought about by the compression springs 30 and the compression spring 27.
  • the locking levers 12 are pivoted outwards by the conical shape of the bolt head until they rest on the cylindrical part of the bolt head 5.
  • the crossbeam 19 is pushed back by the pressure cams 37 of the locking lever 12 by a small amount (approx. 2 mm), the compression springs 27 and 30 also being compressed by the amount and pulling the frame 16 with the prestressing force of the compression springs 39.
  • the cross member 19 When retracting further, the bolt head 5 comes to rest against the front end 21 of the push rod 20 and pushes it back, the cross member 19 also being displaced via the attachments 26 of the driver 25 and the bolt 32 arranged on the cross member 19, which is carried out by the compression springs 27 and 30 formed spring 50 is further tensioned.
  • the cross member 19 pulls the frame 16 via the springs 39 until it is held by the locking levers 12 on its inclined part 18a of the contact contours 18.
  • the couplings are precisely aligned or centered by the centering part 8 of the tension bolt 3 and the centering ring 9.
  • Locking lever (12) H: h is preferably 3: 1.
  • Fig. 4 shows the clutch in the unlocked and uncoupled position, the couplings have not yet been pulled apart.
  • unlocking takes place either from the driver's cab of the train by remote control by switching on the solenoid 45 or an air cylinder or geared motor or by manual actuation of the active part 43.
  • This creates a required feed force V on the frame 16 with a friction coefficient ⁇ 1 between the locking lever and the frame of V ⁇ 1 ⁇ P.
  • the force required for unlocking the unlocking rod is thereby significantly reduced compared to the tensile force acting on the draw bolt.
  • the arrangement according to the invention of a spring accumulator makes it possible for it to be charged when coupling and to release its energy when uncoupling, in order to return the locking mechanism to the "ready to couple” position.
  • the locking lever When engaged, the locking lever is securely locked by the frame.
