Description

Die Erfindung betrifft eine Vorrichtung zum Montieren von Achsen für Schienenfahrzeuge, insbesondere von Niederflurachsen.The invention relates to a device for mounting Axles for rail vehicles, in particular from Low-floor axles.

Bei der Montage von Achsen für Schienenfahrzeuge werden die zu montierenden Räder, Bremssättel etc. jeweils für beide Enden der Achse nacheinander unter Zuhilfenahme von Montagehilfen montiert. Die Aufgabe der Montagehilfen besteht dabei darin, das exakte zentrische und positionsgenaue Ausrichten der einzelnen an der Achse zu montierenden Elemente zu ermöglichen. Darüber hinaus werden die Montagehilfen gegebenenfalls auch für die Befestigung oder das Halten von weiteren Hilfsmitteln benutzt, die zum Befestigen der an der Achse zu montierenden Elemente benötigt werden. Bei diesen Hilfsmitteln kann es sich um Meßuhren für die zentrische und positionsgenaue Einstellung von Kegelrollenlagern, Bremssätteln, Rädern etc. handeln. Ebenso werden Pressen benötigt, um beispielsweise die Lager oder die Räder auf die Achse aufzupressen.When assembling axles for rail vehicles the wheels, brake calipers, etc. to be assembled for both ends of the axis one after the other with the help of Assembly aids installed. The task of the assembly aids consists in the exact centric and positionally accurate alignment of the individual on the axis to enable mounting elements. Furthermore are the assembly aids also for the Attachment or holding other aids used to attach the to the axle too mounting elements are required. With these Aids can be dial gauges for the centric and precise positioning of tapered roller bearings, Act calipers, wheels, etc. Likewise, presses needed, for example, on the bearings or the wheels to press the axle.

Die zur Befestigung der einzelnen Elemente benutzten Montagehilfen haben sich in der Praxis bewährt. Es hat sich jedoch gezeigt, daß aufgrund der Tatsache, daß die einzelnen den beiden Enden der Achsen zugeordneten Elemente einzeln nacheinander montiert werden, ein erheblicher Zeitaufwand für das jeweils erforderliche Justieren der Montagehilfe an dem zu montierenden Achsende benötigt wird.Use those to fix the individual elements Assembly aids have proven themselves in practice. It has it has been shown, however, that due to the fact that the individually assigned to the two ends of the axes Elements are assembled one by one considerable expenditure of time for the respectively required Adjust the assembly aid to the one to be assembled Axle end is needed.

Die Aufgabe der Erfindung besteht darin, eine Vorrichtung zum Montieren von Achsen, insbesondere Niederflurachsen, zu schaffen, mit der die Montage der betreffenden Achsen in kürzerer Zeit durchgeführt werden kann, als dies unter Zuhilfenahme bekannter Montagehilfen möglich ist.The object of the invention is a device for mounting axles, especially low-floor axles, to create with the assembly of the axes concerned can be done in less time than this under Known assembly aids are possible.

Die voranstehend genannte Aufgabe wird erfindungsgemäß mit einer Vorrichtung der eingangs genannten Art gelöst, welche einen auf der Achse aufsetzbaren und lösbar mit dieser verbindbaren Rahmen umfaßt, der an seinen den Enden der Achse zugeordneten Endabschnitten Mittel zum Zentrieren und Halten der jeweils zu montierenden Räder aufweist.The above-mentioned object is achieved according to the invention solved with a device of the type mentioned, which can be placed on the axle and detachable with this connectable framework includes that at its the End portions associated with ends of the axis means for Center and hold the wheels to be mounted having.

Die erfindungsgemäße Montagevorrichtung besteht aus einem Rahmen, der an seinen den beiden Achsenden zugeordneten Enden Abschnitte aufweist, welche Zentriereinrichtungen für die an der Achse zu montierenden Räder tragen. Dies macht es möglich, die erfindungsgemäße Montagevorrichtung vor dem eigentlichen Montagevorgang lösbar mit der zu montierenden Achse zu verbinden und exakt so auszurichten, daß sowohl das eine als auch das andere Ende der Achse ohne ein Umsetzen der Montagevorrichtung montiert werden kann. Auf diese Weise ist es nicht mehr erforderlich, die Montagevorrichtung nach der Fertigmontage des einen Achsendes auf das andere Achsende umzurüsten. Die bei bekannten Montagehilfen für diese Arbeitsgänge erforderliche Arbeitszeit wird daher nicht mehr benötigt. Gleichzeitig kann mit Hilfe des erfindungsgemäßen Rahmens die Montage der Achsen von beiden Seiten gleichzeitig erfolgen. The mounting device according to the invention consists of a Frame that is assigned to the two axle ends End portions has centering devices for the wheels to be mounted on the axle. This makes it possible to use the mounting device according to the invention before the actual assembly process detachable with the to connect the mounting axis and so align that both one and the other End of the axis without moving the mounting device can be assembled. That way it is no longer required the mounting device after the Final assembly of one axle end on the other axle end convert. The known assembly aids for this Working hours required therefore will not needed more. At the same time, with the help of frame according to the invention the assembly of the axes of on both sides at the same time.

Günstig ist es, wenn die Endabschnitte des Rahmens das jeweilige Ende der Achse nach Art eines Käfigs umgreifen. In diesem Fall ist es besonders leicht möglich, an dem Rahmen die Zentriervorrichtung für das Ausrichten und Montieren des jeweiligen Rades zu befestigen. Auch bieten die nach Art von Käfigen ausgebildeten Endabschnitte eine hohe Verwindungssteifigkeit, wodurch die positionsgenaue Montage der zu montierenden Elemente auch unter Belastung sichergestellt ist.It is advantageous if the end sections of the frame grasp each end of the axle in the manner of a cage. In this case it is particularly easy to do that Frame the centering device for aligning and Mount the respective wheel to attach. Also offer the end sections designed in the manner of cages high torsional rigidity, which makes the position accurate Assembly of the elements to be assembled even under load is ensured.

Vorteilhaft ist es auch, wenn an dem jeweiligen Endabschnitt ein Tragarm gelenkig befestigt ist. Dieser Tragarm kann benutzt werden, um verschiedenste für das Montieren benötigte Hilfseinrichtungen zu halten. Dabei können die jeweiligen Hilfsmittel aufgrund der Verschwenkbarkeit des Tragarms auf einfache Weise aus dem jeweiligen Arbeitsbereich herausgeschwenkt werden, um beispielsweise den freien Zugang zum jeweiligen Achsende zu ermöglichen. In diesem Zusammenhang günstig ist es auch, wenn der Tragarm gelenkig an einer seitlich zum jeweiligen Ende der Achse angeordneten Seitenwand des Endabschnitts befestigt ist und mit seinem freien Ende mit der der ersten Seitenwand gegenüberliegenden Wand verriegelbar ist. Auf diese Weise kann der Tragarm zum Abstützen von Einrichtungen benutzt werden, die bei der Montage der auf der Achse zu montierenden Elemente erhebliche Kräfte aufbringen.It is also advantageous if at the respective End section of a support arm is articulated. This Support arm can be used to make various for the Assemble required auxiliary devices. Here can the respective aids because of the Swiveling of the support arm in a simple manner from the respective work area can be swung out to for example free access to the respective axle end to enable. In this context it is cheap also if the support arm is articulated on one side to the each end of the axis arranged side wall of the End section is attached and with its free end with the wall opposite the first side wall can be locked. In this way, the support arm for Supporting facilities are used in the Assembly of the elements to be assembled on the axis apply considerable forces.

Da beispielsweise die zu montierenden Räder in der Regel in einer koaxial zur Längsachse der Achse gerichteten Bewegung auf diese aufgeschoben werden müssen, ist es sinnvoll, wenn wenigstens einer der Tragarme eine koaxial zur Längsachse der Achse verstellbare Aufnahme trägt. Diese Aufnahme kann nicht nur zum Ausrichten des jeweiligen Schienenrades, sondern auch zum Ausrichten oder Befestigen anderer zu montierender Elemente, wie beispielsweise der Bremssättel, genutzt werden.As a rule, for example, the wheels to be assembled in a direction coaxial to the longitudinal axis of the axis It must be postponed movement on this useful if at least one of the support arms is coaxial supports adjustable to the longitudinal axis of the axis. This recording can not only be used to align the respective rail wheel, but also for alignment or attaching other elements to be assembled, such as for example the brake calipers.

Für den Fall, daß die Aufnahme zum koaxialen Verschieben beispielsweise der Räder genutzt werden soll, ist es sinnvoll, wenn die Aufnahme an dem dem jeweiligen Ende der Achse zugeordneten Ende einer Gewindespindel befestigt ist, welche drehbar in einer an dem jeweiligen Tragarm befestigten Führungsmutter gelagert ist. In diesem Zusammenhang vorteilhaft ist darüber hinaus, wenn die Drehachse der Gewindespindel koaxial zur Längsachse der zu montierenden Achse ausgerichtet ist.In the event that the receptacle for coaxial displacement for example, the wheels should be used, it is useful if the recording at the end end of a threaded spindle assigned to the axis is attached, which is rotatable in one at the respective Support arm attached guide nut is mounted. In this context is also advantageous if the axis of rotation of the threaded spindle coaxial to the longitudinal axis the axis to be assembled is aligned.

Eine einfache, zweckentsprechende Möglichkeit der Verstellung der Gewindespindel kann dadurch verwirklicht werden, daß an dem vom Ende der Achse abgewandten Ende der Gewindespindel eine Angriffsfläche für einen Schraubenschlüssel ausgebildet ist. Selbstverständlich kann bei zweckentsprechender Ausbildung der Angriffsfläche auch jedes andere Hilfsmittel zum Drehen der Gewindespindel eingesetzt werden, das hierzu geeignet ist.A simple, appropriate way of This allows adjustment of the threaded spindle be that at the end facing away from the end of the axis the threaded spindle is a target for one Wrench is formed. Of course can with appropriate training the Any other tool for turning is also a target the threaded spindle are used, which is suitable for this is.

Zusätzlich vereinfacht wird das positionsgenaue, zentrische Ausrichten der zu montierenden Elemente dadurch, daß der jeweiligen Aufnahme mindestens ein an dem jeweiligen Tragarm befestigter Zentrierbolzen zugeordnet ist.The positionally precise, centric alignment of the elements to be assembled in that the respective recording at least one centering bolt attached to the respective support arm assigned.

Kostengünstig herstellen läßt sich die erfindungsgemäße Vorrichtung dann, wenn der Rahmen als Schweißkonstruktion aus Stahlprofilen gebildet ist. Ein derart ausgebildeter Rahmen weist eine hohe Stabilität und Verwindungssteifigkeit auf. Darüber hinaus ist es bei einem als Schweißkonstruktion ausgebildeten Rahmen leicht möglich, zusätzliche Aufnahmen oder ähnliches an diesem anzuschweißen, die bei der Montage der Achsen von Nutzen sind.The invention can be produced inexpensively Device if the frame as a welded structure is formed from steel profiles. Such a trained one Frame has high stability and Torsional stiffness. In addition, it is at a frame designed as a welded construction possible additional recordings or the like on this to weld, which is useful in the assembly of the axes are.

Das Aufsetzen der erfindungsgemäßen Vorrichtung auf die zu montierende Achse kann dadurch erleichtert werden, daß an dem Rahmen Bolzen ausgebildet sind, welche nach dem Aufsetzen des Rahmens in Öffnungen der Achse eingreifen. Bei diesen Öffnungen kann es sich beispielsweise um die Aufnahmebohrungen für den Wagenkasten handeln. Dabei kann eine besonders sichere Befestigung des Rahmens auf der Achse dadurch erreicht werden, daß die Bolzen als Schraubenbolzen ausgebildet sind. Auf diese Weise kann nach dem Aufsetzen des Rahmens auf die Achse dieser durch Aufschrauben von Muttern auf die Schraubenbolzen fest mit der Achse verbunden werden.The placement of the device according to the invention on the axis to be assembled can be facilitated in that bolts are formed on the frame, which according to Place the frame into openings in the axle. These openings can be, for example, the Actuate mounting holes for the body. It can a particularly secure attachment of the frame on the Axis can be achieved in that the bolt as Bolts are formed. That way after placing the frame on the axle by Screw nuts tightly onto the bolts the axis.

Das positionsgenaue Ausrichten und Befestigen der einzelnen zu montierenden Elemente kann zusätzlich dadurch begünstigt werden, daß in dem Rahmen Führungen für beispielsweise die Räder, den Bremssattel etc. befestigt sind.The precise alignment and fastening of the individual elements to be assembled can additionally be favored in that guides in the frame for example for the wheels, the brake caliper etc. are attached.
