Definitions

  • the invention relates to an actuating magnet, with an actuating means for exerting a tensile or compressive force on a to be moved, to be switched or arretierendes or de-arret Schl target element, and with a locking means for locking the actuating means in a desired position.
  • An actuating magnet in the form of a lifting magnet which has an armature which is suitable for exerting a tensile or compressive force on a target element to be moved.
  • the known actuating magnet also has locking means for locking the armature.
  • the document GB 1,102,167 A discloses an actuating magnet with magnetic coils and two functioning as an actuating means anchors, which are independently movable by means of the respective magnetic coils.
  • the first armature is provided at its first end with a protruding part which can exert a tensile or compressive force on a target element to be moved via an actuator.
  • the other end of the first anchor is provided with a flange and an adjacent part.
  • the second armature is designed as a movable piston inserted within the first armature and has a conical tip at one end. Further, a locking means for locking the functioning as an actuating means first armature is provided in a desired position.
  • the document DE 196 27 925 A1 discloses an actuating magnet for internal locking of bistable electromagnetic valves.
  • the prior art device has exciting coils which are used to apply a tensile or compressive force to a valve sealing body via an armature tappet.
  • a locking means is provided, which serves for locking the anchor tappet.
  • target element is understood to mean all components of a device which are to be moved, pivoted, switched or locked or deprived, for example electrical switches, locking bolts which are inserted into corresponding locking grooves, pivot bearings and in particular locking devices for coupling arrangements for rail vehicles have at least one pivotable coupling head, and the same similar components.
  • Actuating magnets are known in principle from the prior art. They are used for example in clutch assemblies for rail vehicles their application and allow here, for example, the targeted locking and unlocking the coupling heads or the locking and unlocking of any existing articulated joints.
  • the actuating magnet usually has an actuating means that, when the magnet is activated, exerts a tensile or compressive force on the respective target object.
  • a spring normally prevents unintentional or undesired movement of the actuating element.
  • the prevailing demands often lead to such a phenomenon. This unwanted Movement of the actuator can lead to serious accidents and should therefore be avoided.
  • Object of the present invention is thus to develop an actuating magnet of the type mentioned above such that a secure locking and unlocking of the actuating means of the actuating magnet is ensured
  • this object is achieved by a locking magnet, which allows safe locking and unlocking of the actuating means.
  • a significant advantage here is that even with large acting on the actuating magnet vibrations or accelerations, the actuating means is not moved from its position.
  • the use of a locking means with a locking magnet for locking and unlocking the actuating means guarantees a secure locking of the actuating means in a desired position.
  • EP is, before the actuation of the actuating means, released by means of the locking magnet, the locking device, so that the actuating means of the actuating magnet can be moved freely.
  • Such a design generally has the consequence that, dispensing with expensive and sensitive electronic circuits, with simultaneous delivery of a switching signal for both magnets, first the locking magnet and then the actuating magnet responds and thus first released the lock and then the actuating means of the actuating magnet is moved ,
  • the locking means on a movable by means of the locking magnet locking arm which is arranged transversely to the actuating axis (AA) of the actuating magnet and engages in a locking position in a locking groove on the actuating means of the actuating magnet.
  • This embodiment has several advantages: First, it allows the strict separation between the locking means that locks the actuating means and the locking magnet triggering this locking. Especially with highly loaded actuating magnet, this leads to an extension of the life of the actuating magnet, since the forces of the actuating magnet do not act directly on the sensitive locking magnet but on a preferably robust locking member, here the locking arm. In addition, the aforementioned embodiment allows the space-saving arrangement of the locking magnet, since with a corresponding design of the locking arm almost any orientation and arrangement of the locking magnet is possible. Finally, the use of a rotatably mounted locking arm allows the use of very small locking magnets, which are naturally less powerful than larger models. However, since the well-known lever laws act via the rotatably mounted locking arm, a very small locking magnet with a correspondingly larger stroke or working travel can be used even with larger locking and unlocking forces.
  • the above-mentioned actuating magnet is used in particular also in clutch arrangements for rail vehicles, which have at least one coupling head pivotable in an articulated joint.
  • the above-mentioned actuating magnet in turn serves as a locking device for the articulated joint to lock the coupling head in a certain position or to allow its pivoting.
  • the articulation functions in this case as the target element to be locked or de-locked by the actuating means of the actuating magnet. It is conceivable here, inter alia, the formation of a locking groove in the articulated joint, from which the actuating means of the actuating magnet after its activation slips and so the articulated joint is no longer locked and the coupling head is free to pivot.
  • the locking means according to the invention is used.
  • Fig. 1 shows a detailed isometric exploded view of the actuating magnet 1. Shown is a magnet housing 3, that along an axis A-A movably mounted actuating means 2; 2 '- here explicitly an anchor - includes.
  • the internal structure of this armature housing device corresponds to the known from the prior art embodiment of a standardized electromagnet.
  • the actuating magnet 1 is designed as a simple lifting magnet, which means that a lifting movement in only one direction is possible by the electrical enervation or energization, while the Gegenhubterrorism takes place by an externally applied spring force.
  • the actuating magnet 1 has a spring cup 4, which is fastened by means of screws 9 on the magnet housing 3.
  • This spring cup includes a compression spring 6, via a spring plate 5 against the movably mounted actuating means 2; 2 'is supported.
  • the actuating means 2 has for this purpose a splint hole 13, via which the spring plate 5 is locked by means of a clamping pin 7.
  • the actuating magnet 1 includes an additional locking device, which here exemplarily housed in a lock housing 19 and on the front side of the magnet housing 3 by means Screws 9 'is arranged.
  • the locking device comprises a locking arm 12 (see FIG. 2) which, in the locking state, bears against a locking groove 14 on the actuating means 2 in a locking manner.
  • Fig. 2 shows the actuating magnet 1 according to the invention in a front view.
  • the locking housing 19 is shown that is applied by means of screws 9 'on the magnet housing 3.
  • the locking means has a locking arm 12 which engages with a locking extension 15 in a locking groove 14 on the actuating element 2.
  • the locking arm 12 is mounted rotatably in the locking housing 19 via a bearing pin 16. The activation and deactivation of this locking means is achieved here via a locking magnet 11 in conjunction with a counter-pressure spring 18.
  • This embodiment allows easy replacement of the individual components, since between the locking magnet 11, the counter-pressure spring 18 and the locking arm 12 only compressive forces are to be absorbed and so no tensile forces taking over connection must be formed.
  • the lock housing 19 can be dispensed with the lock housing 19, in which case the individual components of the locking device are to be attached directly to the magnet housing 3 or a corresponding storage.
  • the electrical Enerv réelle the locking magnet 11 is interrupted whereby the locking actuator 17 extends out of the locking magnet 11 and the locking arm 12 is pivoted against the counter-pressure spring 18 and the engagement between locking extension 15 and Locking groove 14 triggers.
  • the locking magnet 11 is constructed identically to the actuating magnet 1 already described in FIG. 1. It therefore also has a spring cup (not shown) which contains a compression spring (not shown). which pushes the locking actuator 17 back to its original position after switching off the Enerv réellesstromes.
  • the entire structure with a locking magnet Execute 11 the locking actuator 17 extends when Enerv réelle and after switching off the Enerv réelle by the force of the counter-pressure spring 18, applied via the locking arm 12, is pushed back into its original position.
  • Fig. 3 shows the actuating magnet 1 described above in a side view, wherein the electrical Enerv michsniklauf is shown schematically.
  • the actuating magnet 1 and the locking magnet 11 is activated by the same current source 20, wherein the output from this switching signal via the same tracks 22; 24 to the magnets 1; 11 is delivered.
  • the locking magnet 11 is considerably smaller in this embodiment in its design than the actuating magnet 1, which means that with simultaneous activation of the two magnets 1; 11 the smaller locking magnet 11 reacts faster and thus the locking (not shown) of the actuating means 2 is released before the actuating magnet 1, the movement of the actuating means 2 along the axis A-A executes.
  • Fig. 4 shows an isometric view of a buckling coupling.
  • This articulated coupling corresponds to a coupling arrangement known from the prior art, consisting of a coupling head 32, which is connected via a coupling shank 31 to a mounting head 33, which in turn can be mounted on a rail vehicle (not shown).
  • the coupling shaft 31 consists here of two components 31a and 31b, which are pivotally connected to each other via an articulated joint 34. This allows, for example, the pivoting of the coupling head 32 in the uncoupled state in a designated protective housing on the rail vehicle (not shown). It should be ensured, however, that it does not unintentionally come to a pivoting of the Kupplungskop fes 32.
  • the hinge 34 has a locking device, which allows a locking of the hinge 34 in the respective desired positions.
  • this locking means comprises a locking bolt 38 which locks in a locking groove (not shown) on the coupling shaft 31b intervenes.
  • this locking pin 38 is pivoted out of the locking groove (not shown).
  • This swinging can be done in different ways.
  • the at least one electric or hydraulic actuator (not shown).
  • an electric actuating magnet is used for this, as previously described.
  • the activation of the actuating magnet takes place via electrical lines 22 '; 24 '.
  • the actuating magnet is arranged so that, after electrical Enerv réelle the locking of its actuating means released by the locking magnet according to the invention and then the actuating means is moved in the direction of the locking pin 38 to move it from its locking position and to allow pivoting of the clutch assembly.
