Abstract
Description
Die Erfindung bezieht sich auf ein spurweitenverstellbares Fahrwerk mit Einzelradsätzen, bei dem das Funktionsprinzip der Spurweitenveränderung des bekannten Systems Talgo so modifiziert wurde, daß sowohl die Federaufhängung System Niesky mittels Schaken für Blatttragfedern als auch die Federaufhängung SNCF 2000 mit Druckfedern verwendet wer-den können.The invention relates to a track-adjustable undercarriage with individual wheel sets, in which the functional principle of changing the track width of the known Talgo system was modified that both the spring suspension system Niesky using shackles for Leaf suspension springs as well as the spring suspension SNCF 2000 with compression springs are used can.
Für den Schienengüterverkehr mit der Iberischen Halbinsel ist das Problem des Spurwechsels
an der Systemgrenze Normalspur 1435 mm / Breitspur 1668 mm von wesentlicher Bedeutung.
An dieser Schnittstelle werden die Ladegüter umgeladen bzw. an geeigneten Güterwagen
werden die Radsätze getauscht.
Da aber umachsfähige Wagen nicht in ausreichender Menge vorhanden sind, die Kapazität
der TRANSFESA - Umachsanlage begrenzt ist und durch das Umladen der Ladegüter es
zu Ladegutbeschädigungen, längeren Wartezeiten und höheren Dispositionsaufwand
kommen kann, sind alternative technische Lösungen notwendig.The problem of changing lanes at the system boundary of normal gauge 1435 mm / wide gauge 1668 mm is of major importance for rail freight transport with the Iberian Peninsula.
The loads are reloaded at this interface or the wheel sets are exchanged on suitable freight wagons.
However, since there are not enough vehicles that can be re-axleed, the capacity of the TRANSFESA re-axleing system is limited and the reloading of the cargo can result in damage to the cargo, longer waiting times and higher planning requirements, so alternative technical solutions are necessary.
Eine Möglichkeit, diese Nachteile zu vermeiden, ist die Anwendung einer automatischen Spurwechseltechnik, wobei für den Güterverkehr gegenwärtig auf keine zugelassene Lösung zurückgegriffen werden kann.One way to avoid these disadvantages is to use an automatic one Lane change technology, although currently no approved solution for freight transport can be used.
Bisher existierte das Halbradsatzsystem der Firma Talgo mit verstellbaren Fahrwerken nur
als Reisezugwagenlaufwerk, wobei die Anlenkung der Losräder über eine spezielle Konstruktion
erfolgt (s. Radsätze mit veränderlicher Spurweite", José Luis Sanchez Gonzalez,
Schienen der Welt, Juli 1982). Dieses Radsatzsystem ist erprobt und zugelassen. Für Gü
terwagen wurde dieses Reisezugwagensystem weiterentwickelt (s.
Es ist für eine Radsatzlast von 22,5 t bei einer Geschwindigkeit bis 120 km/h geeignet und
es kann in Drehgestellen konventioneller Bauart für Güterwagen anstelle der Achsen mit
festem Radabstand montiert werden. Dieses System befindet sich in der Erprobung und ist
noch nicht zugelassen.Up to now, the Talgo half-wheel set system with adjustable undercarriages only existed as a passenger coach drive, with the idler wheels being articulated using a special design (see Wheel sets with variable track width ", José Luis Sanchez Gonzalez, rails of the world, July 1982). This wheel set system has been tested and approved. This passenger car system has been further developed for freight cars (see.
It is suitable for a wheelset load of 22.5 t at a speed of up to 120 km / h and can be mounted in bogies of conventional design for freight cars instead of axles with a fixed wheelbase. This system is currently being tested and has not yet been approved.
Die Achsbaugruppe besteht aus einem Rahmen, an dem die beiden Fahrwerke mit ihren Verriegelungselementen und einer Einrichtung zur Verbindung der Fahrwerke, zwei Armaturen zur Verschiebung der Bremsschuhe, einem System zur Herstellung der elektrischen Verbindung und einer Einrichtung zur Erkennung heißgelaufener innerer Lager montiert wird.The axle assembly consists of a frame on which the two trolleys with their Locking elements and a device for connecting the trolleys, two fittings to move the brake shoes, a system for manufacturing the electrical Connection and a device for detecting hot internal bearings installed becomes.
Darüberhinaus existieren noch weitere automatische Spurwechselsysteme, z.B. die Systeme OGI, RAV, Vevey, Bauart V Rafil/DB AG, die sich noch in Entwicklung bzw. Erprobung befinden und noch keine Zulassung besitzen. There are also other automatic lane change systems, e.g. the systems OGI, RAV, Vevey, type V Rafil / DB AG, which are still in development or testing and are not yet licensed.
Zur Verbesserung der Fahreigenschaften von zweiachsigen Wagen bei gleichzeitiger Anhebung der Geschwindigkeit und der Achsfahrmasse wurden zwei Federaufhängungen entwickelt, welche diese Forderungen erfüllen.To improve the driving characteristics of two-axle wagons while raising them the speed and the axle mass were two spring suspensions developed which meet these requirements.
Aus einer für Drehgestelle mit einstellbaren Radsätzen üblichen Abstützung wurde die Aufhängung
Mit der DE 44 46 687 C2 ist eine Federschake bekannt, die in ihren Auflagebereichen unterschiedliche
Durchmesser aufweist. Gemäß DE 43 05 518 C2 ist außerdem ein Schakengehänge
bekannt, bei dem ebenfalls die Federschake in ihren Auflagebereichen unterschiedliche
Durchmesser und/oder die Federschakensteine unterschiedliche Radien aufweisen.
Dieses weiterentwickelte Einfachlangschakengehänge ist auch als ,

Das erfindungsgemaße Fahrwerk besteht aus einem Rahmen (1), in dem zwei Radsatzsysteme
Talgo mit ihren Verriegelungselementen und den für Einzelradsätze erforderlichen
Radsatzführungen untergebracht sind. Jedes der beiden Radsatzsysteme besteht aus einem
Rad (2), einer kurzen Radsatzwelle (3) und zwei speziellen Radsatzrollenlagern (4 und
5). Diese Einheit kann zur Veränderung der Spurweite im Rahmen (1) axial verschoben
werden.
Beide Radsatzsysteme sind durch längenverstellbare Wellen (6) drehfest miteinander gekuppelt.
Weiterhin ist jedes Radsatzsystem mit einer automatischen Bremsklotzumstelleinrichtung
(7), einem System zur Herstellung der elektrischen Verbindung (8) und einer Einrichtung
zur Erkennung heißgelaufener innerer Radsatzrollenlager (4) ausgerüstet.
Während des Umspurvorganges werden die Räder (2) vollständig über den Rahmen (1) mit
Gleitschuh (9) entlastet und die Verriegelungen der Radsatzrollenlager (4 und 5) im Rahmen(1)
gelöst, wodurch die axiale Verschiebung der kompletten Radsatzrollenlager (4 und
5) mit der Radsatzwelle (3) und dem Rad (2) ermöglicht wird. Nach ihrer Verschiebung werden
die Radsatzsysteme in ihrer neuen Stellung verriegelt.
Wie aus Figur 1 zu entnehmen erfolgt die Aufhängung der Radsatzsysteme einschließlich
Rahmen (1) mit Druckfedern und beidseitig angeordneter lastproportionale Dämpfung
gemäß System SNCF 2000 (10).The chassis according to the invention consists of a frame ( 1 ) in which two Talgo wheel set systems with their locking elements and the wheel set guides required for single wheel sets are accommodated. Each of the two wheelset systems consists of a wheel ( 2 ), a short wheelset shaft ( 3 ) and two special wheelset roller bearings ( 4 and 5 ). This unit can be moved axially in the frame ( 1 ) to change the track width.
Both wheelset systems are coupled to each other by means of length-adjustable shafts ( 6 ). Furthermore, each wheelset system is equipped with an automatic brake pad changeover device ( 7 ), a system for establishing the electrical connection ( 8 ) and a device for detecting overheated inner wheelset roller bearings ( 4 ). During the re-gauging process, the wheels ( 2 ) are completely relieved via the frame ( 1 ) with sliding block ( 9 ) and the locking of the wheelset roller bearings ( 4 and 5 ) in the frame ( 1 ) is released, which causes the axial displacement of the complete wheelset roller bearings ( 4 and 5 ) with the wheelset shaft ( 3 ) and the wheel ( 2 ). After their displacement, the wheelset systems are locked in their new position.
As can be seen in FIG. 1, the wheelset systems including the frame ( 1 ) are suspended with compression springs and load-proportional damping arranged on both sides in accordance with the SNCF 2000 system ( 10 ).
Die Figur 3 zeigt das Radsatzsystem Talgo mit Rahmen in einem radsatzhaltergeführtem
Laufwerk mit Federaufhängung System Niesky (11).
Der Rahmen (1) und das Radsatzrollenlager (5) werden konstruktiv an die Radsatzführung
eines 2- achsigen Güterwagens derart angepaßt, daß das jeweils außenliegende Radsatzrollenlager
(5) Führungswinkel (12) erhält, die die Führung des Radsatzsystems Talgo über
dem Radsatzhalter (13) übernehmen. Der Rahmen (1) wird zur Schaffung des erforderlichen
Freiraumes für die Anordnung der Radsatzhalter (13) nach außen gezogen.
Zur Verhinderung des Herunterklappens des Rahmens (1) infolge von Torsionskräften beim
Bremsen ist der Rahmen (1) über Wankstützen (14) beziehungsweise Seile (15) mit der
Feder (16) und der Federaufhängung (11) verbunden.FIG. 3 shows the Talgo wheelset system with a frame in a wheelset-guided drive with spring suspension system Niesky ( 11 ).
The frame ( 1 ) and the wheelset roller bearing ( 5 ) are structurally adapted to the wheelset guidance of a 2-axle freight wagon in such a way that the respective outer wheelset roller bearing ( 5 ) receives guide brackets ( 12 ) which guide the Talgo wheelset system above the wheelset holder ( 13 ). take over. The frame ( 1 ) is pulled outwards to create the required space for the arrangement of the wheel set holder ( 13 ).
To prevent the frame ( 1 ) from folding down due to torsional forces when braking, the frame ( 1 ) is connected to the spring ( 16 ) and the spring suspension ( 11 ) via anti-roll supports ( 14 ) or ropes ( 15 ).
