The invention relates to a horizontal center adjustment device for a rigid central coupling, in particular for rail vehicles, the horizontal restoring forces of a spring simultaneously stabilizing the running of the coupled vehicles in the horizontal plane and a roller cooperating with roller tracks at the end of the vehicle beyond its pivotable mounting elongated coupling shaft is arranged. ίο

It is primarily used to stabilize the run of the coupled vehicles in horizontal plane serving device known, the two on both sides of the vehicle longitudinal axis side by side has arranged compression springs, which are pivoted horizontally on the vehicle frame and about handlebars with one another and with one another

Pins pivotable coupling are connected. With a horizontal pivoting of the coupling in In curves, the springs are tensioned by means of the handlebars via fixed points. The arrangement of the handlebars and springs is made so that when pivoting the coupling in the desired manner a degressive characteristic of the restoring forces results. This known device is due to the Arrangement of several links, two springs and the necessary joints and guides complicated and prone to repair.

Subject of an older German patent - the version according to this patent is not pre-published - is also primarily used to stabilize the run of the coupled to each other Device serving vehicles in the horizontal plane, in which also the restoring forces become smaller with increasing horizontal deflection of the coupling. This device has a under spring pressure, guided or articulated on the vehicle frame, the lever via telescopic rods or a support triangle is connected to the deflectable coupling. Also this device has a complicated one due to the need for a relatively large number of joints or complex guides and failure-prone structure.

There is also a device of the type specified in which the spring applying the restoring forces presses on a plunger which is displaceable in the longitudinal direction of the coupling shaft and which interacts via a roller mounted at its end with an angled roller track. This known device has the disadvantage that the restoring forces increase with increasing horizontal deflection of the central coupling

instead of becoming smaller, so that this device is not very suitable for horizontal stabilization.

The invention is based on the object of creating a device of the type specified at the beginning, which has a structure that is as simple and robust as possible and which nevertheless maintains a favorable horizontal stabilizing effect with increasing horizontal deflection of the central buffer coupling falling characteristic of the restoring forces is present.

According to the invention, this object is achieved in that the roller is firmly attached to the pivotable roller Storage is mounted on the extended end of the coupling shaft and on both sides of the roller as runways that have one leg of two double-armed levers that can be pivoted on the vehicle are stored and with their other legs held between stops on both sides the spring lock in. When the desired degressive restoring effect is achieved, this solution results in a very high simple design of the device with a small number of wear points, whereby the The need for repairs is particularly low.

The structural design is expediently carried out according to the further invention such that the double-armed levers are angle levers which are pivotably mounted on the vehicle at their apices, with according to a further feature of the invention when driving straight ahead, the apex of the two angle levers have a smaller distance from each other than the ends of the bell crank. Finally can after According to a further concept of the invention, the stops of the angle levers can be adjusted.

An embodiment of the invention is shown schematically in the drawing in a plan view.

A coupling head! is mounted on a rail vehicle 2 via a pivotable mounting 3. At

Claims (4)

I 248 the coupling shaft 4, which is extended beyond the pivotable mounting 3, is mounted at the end of a roller 5 with a vertical axis of rotation. On both sides of the roller 5 roller tracks are arranged with which the roller 5 interacts. The runways are formed by one of the legs of two double-armed angle levers 6 and 7, which are pivotably mounted on the vehicle 2 in their apices 8 and 9 in the horizontal plane. The contact of the roller tracks on the roller 5 is ensured by a pretensioned spring 10 which is arranged between the legs of the angle levers 6 and 7 which face away from the roller 5. The ends of these legs of the angle levers are located between two adjustable stops 11 and 12. The angle levers 6 and 7 are angled so that when driving straight ahead the distance between the apices 8 and 9 of the angle lever is smaller than the distances between the free ends of the angle lever. The center adjustment device according to the invention can be arranged at both ends or, if necessary, only at one end of the vehicle 2. With mutual horizontal pivoting movements of two coupled vehicles of a train, the coupling head 1 is pivoted horizontally. The corresponding angle lever 6 or 7 is pivoted via the roller S, while the respective other angle lever 7 or 6 is prevented from giving way to the side by one of the stops 11, 12, so that the spring 10 is increasingly tensioned. In spite of this increasing spring tension, the force counteracting the pivoting of the coupling decreases with increasing pivoting due to the associated ongoing enlargement of the effective lever arm of the angle lever pivot that interacts with the roller. The characteristic of the stabilizing effect of the device according to the invention can be changed by the adjustable stops 11 and 12. Adjusting these stops changes the preload of the spring 10. Claims: 1. Horizontal center adjustment device for a rigid central coupling, in particular for rail vehicles, the horizontal restoring forces of a spring simultaneously stabilizing the running of the coupled vehicles in the horizontal plane and a roller cooperating with roller tracks at the end of the coupling shaft which is extended beyond its pivotable mounting on the vehicle is arranged, characterized in that the roller (5) is fixedly mounted on the end of the coupling shaft (4) extended beyond the pivotable bearing (3) and on both sides of the roller as roller tracks the one leg of two double-armed levers (6,7 ) , which are pivotably mounted on the vehicle and with their other legs, held between stops (11, 12) , enclose the spring (10) on both sides. 2. Apparatus according to claim 1, characterized in that the double-armed levers (6,7) are angle levers which are pivotably mounted on the vehicle at their apices (8,9). 3. Apparatus according to claim 2, characterized in that when driving straight ahead the vertices (8, 9) of the two angle levers (6,7) have a smaller distance from one another than the ends of the angle lever. 4. Device according to one of claims 1 to 3, characterized in that the stops (11, 12) of the angle lever (6, 7) are adjustable. Considered publications:
