Definitions
- the invention relates to a coupling rod, in particular for a rail vehicle, which has a tie rod unit and a linkage device on both sides.
- a plurality of spring elements for damping the tensile or compressive forces generated during coupling and also a support flange for a connection to a respective rail vehicle are preferably mounted on the two end parts of the tie rod unit.
- a linkage device for a pulling and pushing device has one that can be connected to a coupling head Drawbar, several spring elements mounted on this, in particular for damping the rail vehicle of the compressive and tensile forces arising during coupling, and a flange with a housing that can be connected to the rail vehicle.
- This pull rod for a deflection at least in a horizontal plane is mounted in a plate which is rotatable in the housing and which is arranged between the spring elements.
- the invention is based on the object of creating a coupling rod of the type mentioned at the beginning, which consists of a simple and inexpensive construction.
- this object is achieved in that the two articulation devices provided are rigidly connected to one another on both sides of the tie rod unit, the tie rod unit with its end parts preferably being produced in one piece.
- the tie rod unit with the two articulation devices can thus easily be manufactured according to the invention as an independent structural unit, which can be assembled outside the vehicle and then mounted for connecting two vehicles, for which purpose the two support flanges of the articulation devices can be attached to corresponding brackets in the vehicle body.
- This coupling rod is therefore particularly suitable for freight cars as rail vehicles, which sometimes do not have any shear elements and tubes to absorb impact forces in collisions.
- this tie rod unit which connects the two articulation devices, is manufactured in one piece with the end parts on both sides as a continuous connecting rod. This simplifies the manufacture of this coupling rod and this also results in advantages in terms of strength compared to a multi-part tie rod.
- the connecting rod between the articulation devices is dimensioned with a larger diameter than the end parts for the articulation devices.
- the holding means or the spring elements can be supported directly against the shoulders of the connecting rod formed as stops.
- this tie rod unit connecting the articulation devices is produced by a connecting tube and the end parts as a permanent connection, preferably by welding, to form a one-piece unit.
- the strung together spring elements are supported on the inwardly facing side by locking flanges to each of which one end of the connecting pipe is welded.
- the invention provides for the connection between the articulation devices to be formed by a combination of a one-piece connecting rod with the end parts and a connecting tube slipped over this as a tie rod unit, which is therefore particularly stable and is therefore suitable for rail vehicles that are in operation particularly high tensile and impact forces can occur.
- the tie rod unit In order to increase the spatial deflection of the tie rod unit, it is also provided according to the invention that it is mounted in the associated support flanges arranged between the spring elements.
- the coupling rod 1 shown is particularly suitable for freight cars or similar cars as rail vehicles. It consists of a tie rod unit 4 and a linkage device 2, 3 on both sides, each preferably several on a respective end part 4 ′, 14 of the tie rod unit 4 comprises spring elements 5, 15 mounted on bearings for damping the tensile or compressive forces arising during coupling, as well as a support flange 6, 16 each for attachment to a vehicle body of a respective rail vehicle.
- These spring elements 5, which are lined up outside the respective support flange 6, 16, or the spring elements 15 located inside each of these, are usually made of a resiliently compressible plastic and their number on both sides of the respective support flange 6, 16 is five such elements, which are arranged in rows .
- their number and also the material can be selected differently depending on the requirements. This could vary on both sides between one and more, such as eight such spring elements 5, 15. This depends on the required energy absorption capacity, the stroke and also on the deflection angle of the tie rod unit.
- retaining sleeves 7, 17 are attached to the outside of the end parts 4 ', 14 in a known manner by removable retaining sleeves 7, 17 with loose pressure plates 7', 17 'for supporting the spring elements 5.
- These retaining sleeves 7, 17 preferably each consist of a screw-on nut with a securing element. This enables the spring elements 5, 15 to be pretensioned with a defined pressing force against a respective locking flange 8, 18 on the inner side of the respective end part 4 ′, 14 of the tie rod unit 4.
- both articulation devices 2, 3 are rigidly connected to one another by the tie rod unit 4, the latter being very advantageously in one piece with the end parts 4 ', 14 on both sides as one continuous connecting rod 9 is made. In this way, in addition to achieving better strength, the manufacturing costs of this coupling rod 1 can be reduced.
- this connecting rod 9 between the articulation devices 2, 3 is dimensioned with a larger diameter than the end parts 4 ', 14.
- the tie rod unit 4 For sufficient mobility of the tie rod unit 4 both horizontally and vertically, its end parts 4 ′, 14 are mounted in swivel joints 13 at the support flanges 6, 16.
- the rectangular support flanges 6, 16 are provided, for example, with bores 6 'on both sides. These can of course also be designed differently.
- a tie rod unit 24 is provided, which is produced by a connecting tube 11 and the end parts 4 'as a permanent connection to form a one-piece unit, so that the articulation devices 2 are also rigidly connected to one another by this tie rod unit 4'.
- the end parts 4 ' are each provided with a locking flange 21 on the inside, to which the connecting pipe 11 is welded with one end face each in a coaxial alignment.
- These locking flanges 21 serve, as it were, as stops for the spring elements 15 and they are advantageously assigned in one piece to the end part 4 '.
- FIG. 3 Another variant of a coupling rod 1 according to Fig. 3 based on the one after Fig. 1 . There are therefore again the same reference numerals for the same parts as in the coupling rod 1 according to FIG Fig. 1 and only the differences are explained below.
- both articulation devices 2, 3 are rigidly connected to one another by the tie rod unit 22, which is manufactured in one piece with the end parts 4 ′, 14 on both sides as a continuous connecting rod 9.
- a connecting tube 23 is slipped over this connecting rod 9, with inner sleeves 23 'arranged at the ends between these.
- the connecting pipe 23 strikes locking flanges 8, 18 on both sides. However, it can also be connected to these by welding or the like.
- the retaining sleeves 7, 17 with the loose pressure plates 7 ′, 17 ′ enable the spring elements 5, 15 to be pretensioned with a defined pressing force against the respective locking flange 8, 18 of the tie rod unit 22.
- the connecting rod 9 is provided with the two-sided end parts 4 ', 14 with a continuously identical outer diameter and can therefore be manufactured very easily. In principle, however, could also be done as with the one after Fig. 1 corresponding paragraphs 9, 19 may be provided.
- This coupling rod 1 can thus be designed to be more robust if necessary, which also enables subsequent reinforcement, in particular for the after Fig. 1 but also with those after Fig. 2 permitted.

Description
Die Erfindung betrifft eine Kuppelstange insbesondere für ein Schienenfahrzeug, die eine Zugstangeneinheit und beidseitig je eine Anlenkungseinrichtung aufweist. Auf den beiden Endteilen der Zugstangeneinheit sind jeweils vorzugsweise mehrere Federelemente zum Dämpfen der beim Kuppeln entstehenden Zug- bzw. Druckkräfte und zudem je ein Stützflansch für eine Verbindung mit einem jeweiligen Schienenfahrzeug gelagert.The invention relates to a coupling rod, in particular for a rail vehicle, which has a tie rod unit and a linkage device on both sides. A plurality of spring elements for damping the tensile or compressive forces generated during coupling and also a support flange for a connection to a respective rail vehicle are preferably mounted on the two end parts of the tie rod unit.
Eine Anlenkungseinrichtung einer Zug- und Stossvorrichtung gemäss der Druckschrift
Der Erfindung liegt die Aufgabe zugrunde, eine Kuppelstange der eingangs genannten Gattung zu schaffen, die aus einer einfachen und kostengünstigen Konstruktion besteht.The invention is based on the object of creating a coupling rod of the type mentioned at the beginning, which consists of a simple and inexpensive construction.
Diese Aufgabe ist erfindungsgemäss dadurch gelöst, dass die beiden vorgesehenen Anlenkungseinrichtungen beidseitig der Zugstangeneinheit starr miteinander verbunden sind, wobei die Zugstangeneinheit mit ihren Endteilen dabei vorzugsweise einstückig hergestellt ist.According to the invention, this object is achieved in that the two articulation devices provided are rigidly connected to one another on both sides of the tie rod unit, the tie rod unit with its end parts preferably being produced in one piece.
Die Zugstangeneinheit mit den beiden Anlenkungseinrichtungen kann somit erfindungsgemäss als eigenständige Baueinheit einfach gefertigt werden, die ausserhalb des Fahrzeugs zusammengesetzt und anschliessend für das Verbinden von zwei Fahrzeugen montiert werden kann, wozu die Befestigung beider Stützflansche der Anlenkungseinrichtungen an entsprechenden Halterungen bei den Fahrzeugkasten erfolgen kann.The tie rod unit with the two articulation devices can thus easily be manufactured according to the invention as an independent structural unit, which can be assembled outside the vehicle and then mounted for connecting two vehicles, for which purpose the two support flanges of the articulation devices can be attached to corresponding brackets in the vehicle body.
Diese Kuppelstange eignet sich damit insbesondere für Güterwagen als Schienenfahrzeuge, die vorzugsweise mitunter keine Abscherelemente und Rohre zum Absorbieren von Stosskräften bei Zusammenstössen aufweisen müssen.This coupling rod is therefore particularly suitable for freight cars as rail vehicles, which sometimes do not have any shear elements and tubes to absorb impact forces in collisions.
Es ist gemäss der Erfindung in einer ersten Variante vorgesehen, dass diese die beiden Anlenkungseinrichtungen verbindende Zugstangeneinheit mit den beidseitigen Endteilen einstückig als eine durchgehende Verbindungsstange hergestellt ist. Dies vereinfacht die Fertigung dieser Kuppelstange und es ergeben sich dadurch auch festigkeitsmässig Vorteile gegenüber einer mehrteiligen Zugstange.According to the invention, it is provided in a first variant that this tie rod unit, which connects the two articulation devices, is manufactured in one piece with the end parts on both sides as a continuous connecting rod. This simplifies the manufacture of this coupling rod and this also results in advantages in terms of strength compared to a multi-part tie rod.
Die Verbindungsstange zwischen den Anlenkungseinrichtungen ist mit einem grösseren Durchmesser als die Endteile für die Anlenkungseinrichtungen dimensioniert. Dadurch können die Haltemittel bzw. die Federelemente direkt gegen die als Anschläge gebildeten Absätze der Verbindungsstange abgestützt werden.The connecting rod between the articulation devices is dimensioned with a larger diameter than the end parts for the articulation devices. As a result, the holding means or the spring elements can be supported directly against the shoulders of the connecting rod formed as stops.
Bei einer zweiten Variante ist erfindungsgemäss vorgesehen, dass diese die Anlenkungseinrichtungen verbindende Zugstangeneinheit durch ein Verbindungsrohr und den Endteilen als unlösbare Verbindung, vorzugsweise durch Schweissen, zu einer einstückigen Einheit hergestellt ist. Mit dieser Lösung kann die Vorrichtung leichter gebaut werden.In a second variant, it is provided according to the invention that this tie rod unit connecting the articulation devices is produced by a connecting tube and the end parts as a permanent connection, preferably by welding, to form a one-piece unit. With this solution, the device can be built more easily.
Es ist dabei herstellungstechnisch vorteilhaft, wenn bei den Anlenkungseinrichtungen die aneinandergereihten Federelemente auf der gegen innen zugekehrten Seite durch Arretierflansche gestützt sind, an welchen je ein Ende des Verbindungsrohr angeschweisst ist.It is advantageous from a manufacturing point of view if, in the articulation devices, the strung together spring elements are supported on the inwardly facing side by locking flanges to each of which one end of the connecting pipe is welded.
Bei einer dritten Variante sieht die Erfindung vor, die Verbindung zwischen den Anlenkungseinrichtungen durch eine Kombination einer einstückigen Verbindungsstange mit den Endteilen und einem über diese gestülpten Verbindungsrohr als Zugstangeneinheit zu bilden, welche damit besonders stabil ausgeführt und sich somit für Schienenfahrzeuge eignet, bei denen im Betrieb besonders hohe Zug- und Stosskräfte auftreten können.In a third variant, the invention provides for the connection between the articulation devices to be formed by a combination of a one-piece connecting rod with the end parts and a connecting tube slipped over this as a tie rod unit, which is therefore particularly stable and is therefore suitable for rail vehicles that are in operation particularly high tensile and impact forces can occur.
Um die räumliche Auslenkung der Zugstangeneinheit zu erhöhen, ist es auch erfindungsgemäss vorgesehen, dass sie in den dazugehörigen Stützflanschen zwischen den Federelementen angeordneten Drehgelenken gelagert ist.In order to increase the spatial deflection of the tie rod unit, it is also provided according to the invention that it is mounted in the associated support flanges arranged between the spring elements.
