Definitions

  • the invention relates to a coupling, in particular for a rail vehicle, with a coupling head which is provided with a locking and unlocking mechanism and with an electric coupling for the connection of electric lines, according to the preamble of claim 1.
  • the electric coupling is driven by a pneumatic or electric drive whose control functions via valves or switches.
  • Such a clutch is in the EP 3 750 771 A1 disclosed, in which the electric clutch couples pneumatically by a cylinder-piston unit, the control of which is carried out with the compressed air of the main air line via two-way and multi-way valves.
  • a control in the usually rough driving operation, disturbances can arise, also because of the sensors to be activated.
  • the object of the invention is to avoid the disadvantages mentioned above and to create a clutch of the type mentioned at the outset, which ensures functionally reliable control of the electric clutch drive using structurally simple means.
  • this object is achieved in that mechanical adjustment means are integrated in the electro-coupling, by means of which it can be moved forwards into the coupled position or backwards into the uncoupled position.
  • a locking means that can be actuated by the locking and unlocking mechanism and is operatively connected to one of the mechanical adjustment means is integrated in the coupling head, by means of which locking means the electric coupling is released for coupling.
  • the invention provides that the electric clutch is integrated with a compression spring for the forward movement and a cable pull as an adjusting means for the retraction, the activation of which is kinematically connected to the locking and unlocking mechanism axis takes place, which interacts during coupling and uncoupling with a stop on the guide tube that limits the mobility of the electric coupling.
  • an air coupling is equipped with a spring-loaded coupling piece that can be pushed forwards by the spring force and, in the decoupled state, protrudes from the contact surface of the coupling head, whereby during the coupling process the coupling piece can be driven over laterally by the other coupling head and pushed backwards against the spring force acting on it .
  • FIG. 1 shows a coupling especially for rail vehicles with a mechanical coupling head 1 and an electric coupling 4 for electrical lines.
  • a main air line 3 and an air coupling 2 contained therein is illustrated, which protrudes from the front at a contact surface 10.
  • a container air line could also be provided.
  • a guide vane 30 is provided which projects laterally to the contact surface 10 and clamping jaws 31 are provided on the rear for fastening the same to a connecting part 32.
  • the electrical lines of the rail vehicles are connected to one another in such a way that the power supply and electrical control lines to the coupled vehicles are guaranteed.
  • An electric coupling 4 is mounted on the front and rear of each rail vehicle in such a way that they can each be coupled to any other vehicle when driving against one another.
  • the electro-coupling 4 is fitted in a cylinder 11 and in a tubular housing 26 supporting it below the coupling head 1 and is mounted such that it can be moved back and forth together with a guide sleeve 12 which is similar to a piston rod.
  • a guide sleeve 12 which is similar to a piston rod.
  • plugs or sockets 6 for connecting the electric lines and a cover 21 are arranged.
  • This closure cover 21 is advantageously pivotably mounted and, if necessary, can be pressed at least approximately perpendicularly onto the support surface by a lever arm of an angle lever. It is used either for the sealing closure of the plugs or sockets 6 in the uncoupled state, as shown, or for releasing the same in its pivoted open position in the coupled state of the same.
  • the electric lines are routed from the plugs through the cylinder 11 and the guide sleeve 12 into the respective vehicle.
  • the tubular housing 26 is provided at the opposite end to the plugs 6 with a final hub 22 in which the guide sleeve 12 is mounted so that it can move longitudinally.
  • a sleeve 23 Inside the cylinder 11 is a sleeve 23 and in the latter the guide sleeve 12 is fixed at the front end.
  • This sleeve 23 protrudes laterally from the tubular housing 26 Web 18 associated with a stop 18 ', which cooperates with a locking and unlocking mechanism in the coupling head 1 actuated locking means 25.
  • This locking means 25 has an axis 16 which extends into the coupling head 1 and is rotatably connected to a locking and unlocking mechanism of the coupling in the coupling head, which is not shown in detail.
  • a longitudinal groove 27 is formed in the tubular housing 26, through which this protruding web 18 is guided, which is accommodated together with the locking means 25 in a sealed holder 28 of the tubular housing 26 on the coupling head 1.
  • a spring element and a cable running inside it are integrated, each as a mechanical adjusting means 13, 14.
  • the spring element is designed as a compression spring 13 and the cable 14, which can be actuated externally, extends through the hub 22 of the tubular housing 26 into the front area of the cylinder 11 Contact surface 10 pulled away to the rear.
  • the locking and unlocking mechanisms When coupling a coupling head of another rail vehicle with the coupling head 1, the locking and unlocking mechanisms are activated mechanically, from the in 1 only a locking element 15 is visible, which is swiveled in by the other coupling head and thus initiates the coupling and the locking.
  • the axis 16, which is kinematically connected to the locking and unlocking mechanism, is also rotated with its head piece 17 through a certain angle and the web 18 and with it the cylinder 11 are released. which are pushed forward by the adjusting means 13, so that the electric coupling 4 is coupled to that of the coupling rail vehicle by plugging.
  • the electric clutch 4 can be moved in its longitudinal axis into three positions “coupled”, “uncoupled” or “ready for coupling”, which is advantageous compared to the previous clutches with only two positions.
  • the electric coupling 4 is pushed forward by the integrated adjusting means 13 until the stop 18 on the head piece 17 on the guide sleeve 12 is blocked. This position is released via a rotary movement of the axis 16 by the locking and unlocking mechanism 15, which then changes into its locking position and the electric clutch 4 is thus likewise coupled.
  • the electric clutch 4 In the “disengaged” position, the electric clutch 4 is disengaged by the externally manually operable cable as adjusting means 14 and blocked at the rear end of the axle 16, with the locking and unlocking mechanism 15 moving into its unlocked position.
  • the air coupling 2 of the main air line 3 has a sleeve-shaped coupling piece 7, which is slidably mounted in a guide sleeve 8 fastened in the coupling head 1 and is pressed forward by a compression spring 9 surrounding it in such a way that it is in the decoupled state shown with its front surface 7 'to the contact surface 10 of the coupling head 1 protrudes slightly, to an annular stop surface 8' is provided on the inside of the guide sleeve 8 for the coupling piece 7.
  • the front surface 7′ is expediently designed in a conical manner in such a way that it runs approximately flush with the contact surface 10 on the outer circumference.
  • the coupling piece 7 is then run over laterally by the coupling head of the other vehicle and pushed backwards against the spring force of the compression spring 9 acting on it to such an extent that an airtight connection is established with the counterpart of the other coupling head, in which the coupling piece 7 is in the coupling position again snaps forward into an opening in the other coupling head.
  • the connection of the air coupling 2, including its activation by the coupling coupling head, thus takes place automatically without the need for any actuating elements.
  • an adjusting means in the form of a screw, bayonet or the like could be used, which would effect the uncoupling by turning instead of pulling.
  • an electric or piston drive could also be provided as the adjusting means, which could be activated by an actuating element such as a rotary, pressure or similar switch, with these also being controlled in the vicinity of the coupling or from the driver's cab in the locomotive or could be done from somewhere external.
