Definitions

the invention relates to a train coupling according to the preamble of claim 1.
the object of the invention is to design a train coupling of the type in question so that coupling in the curve of the track is possible without the side buffers having to be pressed in, nevertheless it should be ensured that there are no excessive longitudinal impact forces on the straight track occur that normal dome spacing can be maintained.
the coupling shown in the drawing in partial section according to the invention has a coupling arm 1, which is preferably articulated by means of an elongated hole 3 on a joint 5.
the coupling arm 1 is assigned a coupling head 7 which is longitudinally displaceable in it and on which an angle lever 9 is pivotably arranged.
the coupling arm is arranged on the end face of a rail vehicle, the coupling head being able to be coupled to the counter-coupling head of a further rail vehicle.
pulling elements such as pulling hooks, are provided on the coupling head (not shown in the drawing), which are able to engage in a coupling manner with the corresponding counterparts of the counter-coupling head (not shown). It is a pure train coupling.
the angle lever 9 is articulated on a so-called button 11, which extends in the longitudinal direction through a bore 13 of the Coupling head 7 extends, at the front, that is, as shown in the drawing left end of the button 11, a button head 15 is formed, against which a spring 17 acts, the spring 17, which is supported on an inside shoulder of the coupling head 7, has the tendency to axially follow the button to move outside.
the coupling head 7 has in the interior of the coupling arm a radially projecting stop 19 which, in the manner described below, can come into contact with an inwardly projecting stop 21 of the coupling arm 1.
the stop 21 can also cooperate with a stop 23 projecting outside the coupling arm 1 from the coupling head, as a result of which a movement of the coupling head 7 toward the right can be limited.
a spring 25, which is supported on a stationary abutment 27 of the rail vehicle, acts against an extension 29 which projects outwards from the coupling head 7, so that the coupling head is directed to the left in the manner also described below by the force of the spring 25 as shown in the drawing is movable.
the angle lever 9 is rotatable by actuation by the button around the center of the bearing 31 and acts against a stop 33 which projects laterally from a pawl 34, with the result that the pawl can be pivoted about its bearing 35 when the angle lever 9 is rotated and can disengage from the engagement in a recess or in a slot 37 of the coupling head 7.
the coupled position is shown, in which the button 11 is shifted into the position shown by the mating coupling head (not shown), the spring 17 correspondingly is tense.
the button 11 becomes free in that it can move axially outward from the coupled position shown in the drawing. This is done in that the spring 17 acts on the button head 15 and thus pushes the button 11 directed outwards.
the angle lever 9 connected to the button 11 rotates correspondingly around the center of the bearing 31, so that the leg 39 of the angle lever acts on the stop 33 and lifts it out together with the pawl 34 from the slot 37 as shown in the drawing.
the coupling head 7, which is under the action of the spring 25, is moved after unlocking, ie after lifting the pawl 34, as shown to the left, that is to say the push button head 15 is moved by a corresponding, predeterminable amount.
the coupling head 7 thus assumes an advanced position in which it is in the coupling position; this position is of particular advantage when coupling in the track curve, ie when the distances between the rail vehicles to be coupled are greater in the area of their center line.
the button head 15 When coupling, the button head 15 is first pressed in by the corresponding mating coupling head or its button, whereby the pawl 34 has the possibility of falling back into the slot 37 as soon as the coupling head 7 is pushed back as far as the train is pushed further in a straight track so that its front contour 45 comes to lie at the level of the level 47 of the side buffers. In such a position, the coupling is automatically shortened in the aforementioned manner in order to be automatically extended to the required extent after a subsequent disconnection.
pawl 34 and the angle lever 9 there are also other pawls, e.g. in the manner of a Willison clutch, can be used.
the coupling is preferably mounted in the elongated hole 3, the stop 23 coming into contact with the stop 21 if necessary, or a stop at the end 49 of the coupling head 7 acting against the coupling arm 1 is, while at the same time there must be a correspondingly large game in the recess or in the slot 37.
the pawl 34 can optionally be reinforced by additional springs.
An additional device for example a handle 51 shown in the drawing, which is connected to the pawl 34, makes it possible, by pulling this handle and possibly by fixing it (for example by a pawl not shown), to release the pawl from engagement to bring the coupling head 7. In this way, the coupling could be brought into the long position in the case of coupled vehicles which are standing in a curve, in order subsequently to facilitate unlocking. Since in this case the surfaces 41 and 43 press against one another under a correspondingly high load, it may be appropriate to interpose a corresponding lever ratio between the pawl 34 and the handle 51 or even to provide a releasable auxiliary drive for this.
