Abstract

The invention relates to a bogie for rail vehicles in which a transverse spring path is present between the carriage body (9) of the rail vehicle and the wheels or wheel sets (4) of the bogie. The object of the invention consists in finding a way of decoupling carriage body (9) and wheels or wheel sets (4) which acts not only in straight pieces of track but also when going round bends with an excess of centrifugal force, so that the decoupling in the bend corresponds virtually to that in straight pieces of track. This object is achieved in that carriage bodie (9) and wheels or wheel sets (4) are connected to one another directly or with the intermediate connection of components of the bogie by means of an air cylinder (12) adjustment element which, when there is an excess of centrifugal force, keeps the carriage body (9) near to the centre position in a strong fashion with variable spring force. At the same time, the spring force of the air cylinder (12) adjustment element is controlled by a displacement sensor and/or force sensor (displacement meter 21) which measures the relative movement between carriage body (9) and wheels or wheel sets (4) ... a control circuit (control element 22) connected downstream thereof. <IMAGE>

Description

Die Erfindung betrifft ein Laufwerk für Schienenfahrzeuge bei dem ein Querfederweg zwischen dem Wagenkasten des Schienenfahrzeugs und den Rädern oder Radsätzen des Laufwerks vorhanden ist.The invention relates to a drive for rail vehicles in which there is a transverse spring travel between the body of the rail vehicle and the wheels or wheelsets of the drive.

Der genannte Querfederweg ist erforderlich, um eine Entkopplung zwischen den Rädern bzw. Radsätzen des Laufwerks und dem Wagenkasten zu erreichen. Diese Entkopplung ist notwendig, um ein hohes Maß an Laufkomfort zu gewährleisten und unerwünschte Querstöße im Wagenkasten zu vermeiden.The above-mentioned transverse spring travel is necessary in order to achieve a decoupling between the wheels or wheel sets of the drive and the car body. This decoupling is necessary in order to ensure a high level of running comfort and to avoid undesirable cross bumps in the car body.

Bekannt sind Entkopplungen mit linear oder progressiv ansteigenden Querkennlinien und linear bzw. progressiv bzw. linear und dann progressiv verlaufenden Querkennlinien. Der Querweg zwischen Wagenkasten und Rädern oder Radsätzen ist begrenzt durch die Anforderung an größtmöglichen Fahrgastraum oder Wagenquerschnitt einerseits und dem zur Verfügung stehenden Umgrenzungsprofil für Schienenfahrzeuge andererseits. Üblicherweise wird ein Teil des zur Verfügung stehenden Querweges durch die meist linieare Quersteifigkeit der Vertikalfeder und zur Abdeckung größerer quasistatischer Fliehkräfte bei Bogenfahrt ein weiterer Teil des zur Verfügung stehenden Querweges durch eine progressive zusätzliche Querfederung, z. B. in Form eines Gummipuffers genutzt.Decouplings with linear or progressively increasing transverse characteristic curves and linear or progressive or linear and then progressive transverse characteristic curves are known. The transverse path between the body and the wheels or wheelsets is limited by the requirement for the largest possible passenger compartment or wagon cross-section on the one hand and the boundary profile available for rail vehicles on the other. Usually, part of the available transverse path through the mostly linear transverse stiffness of the vertical spring and to cover larger quasi-static centrifugal forces when traveling through bends another part of the available transverse path through a progressive additional transverse suspension, e.g. B. used in the form of a rubber buffer.

Nachteilig bei dieser vorbeschriebenen Querentkopplung ist, daß bei Bogenfahrt schon unter geringem Fliehkraftüberschuß der Wagenkasten sich im Bereich der progressiven Querkennlinie befindet. Da der Fliehkraftüberschuß bei Bogenfahrt kontinuierlich wirkt, ergibt sich für diesen Zustand ein neuer quasistatischer Gleichgewichtszustand. Aufgrund von Gleislagefehlern wird das Fahrzeug in diesem neuen Gleichgewichtszustand noch mit Stößen beaufschlagt. Diese Stöße werden durch die höhere Quersteifigkeit dieses Gleichgewichtszustandes (Progressivität des Querpuffers) mit einer harten Kopplung zwischen Wagenkasten und Rädern oder Radsätzen in den Wagenkasten übertragen.A disadvantage of this cross-decoupling described above is that, when traveling through bends, the car body is in the region of the progressive transverse characteristic even with a slight excess of centrifugal force. Since the excess centrifugal force acts continuously when traveling through bends, a new quasi-static equilibrium state results for this state. Due to track position errors, the vehicle is still subjected to shocks in this new state of equilibrium. These shocks are transmitted through the higher transverse rigidity of this state of equilibrium (progressiveness of the transverse buffer) with a hard coupling between the body and wheels or wheelsets in the body.

Das Ziel der Erfindung bestand darin, eine Entkopplung zwischen Wagenkasten und Rädern oder Radsätzen zu finden, die nicht nur in der Geraden, sondern auch bei Bogenfahrt unter Fliehkraftüberschuß so wirkt, daß die Entkopplung im Bogen nahezu derjenigen in der Geraden entspricht.The aim of the invention was to find a decoupling between the body and wheels or wheelsets, which not only acts in the straight line, but also when traveling under bends with excess centrifugal force, so that the decoupling in the bend corresponds almost to that in the straight line.

Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß Wagenkasten und Räder bzw. Radsätze direkt oder unter Zwischenschaltung von Bauteilen des Laufwerks durch ein Stellelement miteinander verbunden sind, daß mit variabler Federkraft den Wagenkasten bei Fliehkraftüberschuß federnd nahe der Mittellage hält. Hierbei ist die Federkraft des Stellelementes gesteuert durch einen die Relativbewegung zwischen Wagenkasten und Räder oder Radsätzen messenden Weg- und/oder Kraftsensor und einen diesem nachgeschalteten Regelkreis. Das Stellelement ist dabei hydraulisch, pneumatisch oder elektromotorisch beaufschlagbar.According to the invention, this object is achieved in that the car body and wheels or wheel sets are connected to one another directly or with the interposition of components of the drive by an actuating element that keeps the car body resiliently close to the central position with excess centrifugal force. Here, the spring force of the control element is controlled by a displacement and / or force sensor measuring the relative movement between the body and wheels or wheel sets and a control circuit connected downstream of the latter. The actuating element can be acted upon hydraulically, pneumatically or by an electric motor.

Durch die Erfindung wird vorteilhaft auch im Bogenlauf eine gute Entkopplung zwischen Wagenkasten und Rädern oder Radsätzen erreicht. Der Laufkomfort wird dadurch im Bogenlauf wesentlich verbessert. Querstöße werden vermieden und das Durchleiten von hochfrequenten Querschwingungen unterbleibt.By means of the invention, good decoupling between the car body and the wheels or wheel sets is advantageously achieved even in sheet travel. This significantly improves running comfort in sheet travel. Cross jolts are avoided and the passage of high-frequency cross vibrations is avoided.

Durch die Regelung kann weiter eine geringe Quersteifigkeit im jeweiligen Gleichgewichtszustand erreicht werden.The control can also achieve a low transverse stiffness in the respective state of equilibrium.

Einzelheiten der Erfindung sind an Hand eines Ausführungsbeispiels in der Zeichnung erläutert.Details of the invention are explained using an exemplary embodiment in the drawing.

The transverse spring characteristic of a rail vehicle conventional and with decoupling according to the invention
The drive shown in the drawing consists essentially of an H-shaped drive frame (1) with two cross members (2). Wheel sets (4) are supported on the side long beams (3) of the drive frame (1) via primary springs (5). Between the cross members (2) of the drive frame, a cradle cross member (6) is supported by air springs (7) on the side long members (3). A receptacle for the pivot pin (8) of the car body (9) is provided centrally in the cradle cross member (6). On the cradle cross member (6) are near the transverse ends of sliders (10) for supporting the car body (9).

Der Wagenkasten (9) ist mit dem Wiegenquerträger (6) quer beweglich über die Luftfeder (7) auf dem Laufwerkrahmen (1) gelagert.The car body (9) is mounted with the cradle cross member (6) so that it can move transversely via the air spring (7) on the drive frame (1).

An den Seitenlangträgern (3) des Laufwerkrahmens (1) ist innen je ein Luftzylinder (12) gelenkig befestigt, der mit seiner Kolbenstange (13) ebenfalls gelenkig am Wiegenquerträger (6) gelagert ist. Die Luftzylinder (12) sind doppelt wirkend ausgebildet. Beide Arbeitsräume (Kolbenraum (14) und Ringraum (15)) jeden Luftzylinders (12) sind durch Luftleitungen (16) verbunden, wobei der Kolbenraum (14) jeweils eines Luftzylinders (12) mit dem Ringraum (15) des anderen Luftzylinders (12) durch die Luftleitungen (16) verbunden ist. Die Luftleitungen (16) wiederum sind verbunden mit einem Luftbehälter (17), der von einem Drucklufterzeuger (19) gefüllt wird. Ein dem Luftbehälter (17) nachgeschalltetes Überdruckventil (18) sowie ein Luftmengenregler (20) regeln generell die Luftzufuhr zu den Steuerelementen (22).An air cylinder (12) is articulated inside each of the side long beams (3) of the drive frame (1) and is likewise articulated on the cradle cross member (6) with its piston rod (13). The air cylinders (12) are double-acting. Both working chambers (piston chamber (14) and annulus (15)) of each air cylinder (12) are connected by air lines (16), the piston chamber (14) of one air cylinder (12) each with the annulus (15) of the other air cylinder (12) through the air lines (16) is connected. The air lines (16) are in turn connected to an air tank (17) which is filled by a compressed air generator (19). A pressure relief valve (18) downstream of the air tank (17) and an air volume regulator (20) generally regulate the air supply to the control elements (22).

Jeder Luftzylinder (12) ist mit einem Wegmesser (21) ausgestattet, über den in die Luftleitungen (16) zwischengeschaltete Steuerelemente (22) die Luftzufuhr bzw. Luftentnahme der Luftzylinder (12) geregelt wird.Each air cylinder (12) is equipped with a travel meter (21), via which control elements (22) interposed in the air lines (16) regulate the air supply or air extraction of the air cylinders (12).

In Mittenstellung des Wagenkastens (9) ist jeder Arbeitsraum (Kolbenraum (14), Ringraum (15)) jeden Luftzylinders (12) mit gleich hohem Luftdruck beaufschlagt. In dieser Stellung sind alle Arbeitsräume (Kolbenraum (14), Ringraum (15)) der Luftzylinder (12) über die Luftleitungen (16) durchgängig miteinander verbunden. Es kann ein Austausch der unter Druck stehenden Luftmengen beider Luftzylinder (12) ohne Rückstellkräfte stattfinden.In the middle position of the car body (9), each working chamber (piston chamber (14), annular chamber (15)) of each air cylinder (12) is acted upon with the same high air pressure. In this position, all working spaces (piston space (14), annular space (15)) of the air cylinders (12) are continuously connected to one another via the air lines (16). The pressurized air quantities of both air cylinders (12) can be exchanged without restoring forces.

Bei einem Auswandern des Wagenkastens (9) mit dem Wiegenquerträger (6) aus der Mittelstellung, z. B. bei Kurvenfahrt, durch den Fliehkraftüberschuß mißt der Wegmesser (21) der Luftzylinder (12) den Querweg und gibt diese Information an die Steuerelemente (22) weiter.When the car body (9) migrates with the cradle cross member (6) from the central position, e.g. B. when cornering, by the centrifugal excess, the odometer (21) of the air cylinder (12) measures the transverse path and passes this information on to the controls (22).

Das Steuerelement (22), daß in die Luftleitung (16) der belasteten Arbeitsräume (Kolbenraum (14), Ringraum (15)) beider Luftzylinder (12) zwischengeschaltet ist, sperrt jetzt diese Luftleitung (16) und bewirkt damit ein statisches Luftpolster, während das Steuerelement (22), daß in die Luftleitung der unbelasteten Arbeitsräume (Kolbenraum (14), Ringraum (15)) der Luftzylinder (12) zwischengeschaltet ist, die in diesen Arbeitsräumen vorhandene Druckluft abblasen läßt. Durch die so entstehende Druckminderung in den unbelasteten Arbeitsräumen (Kolbenraum (14) bzw. Ringraum (15)) der beiden Luftzylinder (12) kommt das in den belasteten Arbeitsräumen abgesperrte Luftpolster voll zum Tragen. Die Querkraft wird abgefangen und der Wagenkasten (9) mit dem Wiegenquerträger (6) etwa in Mittellage zurückgeführt. Nach Beendigung des Fliehkraftüberschusses, d. h. bei Geradeausfahrt des Fahrzeugs wird über die entsprechende Information des Wegmessers (21) an die Steuerelemente (22) die Ausgangssituation wieder hergestellt. Der Wegmesser (21) und die Steuerelemente (22) sind zweckmäßiger Weise so ausgebildet, bzw. eingestellt, daß geringe Querwege des Wagenkastens (9) mit dem Wiegenquerträger (6), z. B. beim Sinuslauf in der Geraden und bei Gleislagefehlern in der Geraden die Steuerelemente nicht ansprechen lassen.The control element (22), that in the air line (16) of the loaded working spaces (piston chamber (14), annular space (15)) of both air cylinders (12) is interposed, now blocks this air line (16) and thus causes a static air cushion while the control element (22) that in the air line of the unloaded work spaces (piston chamber (14), annular space (15)) of the air cylinder (12) is interposed, which allows existing compressed air to be blown off in these work spaces. The resulting reduction in pressure in the unloaded work spaces (piston chamber (14) or annular space (15)) of the two air cylinders (12) means that the air cushion blocked in the loaded work spaces is fully effective. The transverse force is intercepted and the car body (9) with the cradle cross member (6) is returned approximately in the middle position. After the centrifugal excess has ended, d. H. when the vehicle is traveling straight ahead, the starting situation is restored via the corresponding information from the odometer (21) to the control elements (22). The odometer (21) and the control elements (22) are expediently designed or set so that small cross paths of the car body (9) with the cradle cross member (6), for. B. with sinusoidal movement in the straight line and with track position errors in the straight line, the controls do not respond.

Es ist weiter denkbar, anstelle der zwei Luftzylinder (12) gemäß vorstehend beschriebenen Ausführungsbeispiel nur einen Luftzylinder (12) zu verwenden.It is further conceivable to use only one air cylinder (12) instead of the two air cylinders (12) according to the exemplary embodiment described above.

Es ist weiter denkbar, anstelle der Druckluftelemente, Hydraulikelemente mit Gaspolster zu verwenden. Es ist auch weiter denkbar, die Stellelemente elektromotorisch, eventuell mit Gaspolster zu beaufschlagen.It is also conceivable to use hydraulic elements with a gas cushion instead of the compressed air elements. It is also conceivable to apply electric cushioning to the control elements, possibly with a gas cushion.

Es ist ebenso denkbar, daß mittels einer entsprechenden Elektronik die Steuerelemente so geregelt werden, daß eine beliebige Kennlinie der Querentkopplung erreicht wird.It is also conceivable that the control elements are regulated by means of appropriate electronics in such a way that any desired characteristic of the transverse decoupling is achieved.

Die Anordnung der Erfindung ist nicht auf das in der Ausführung beschriebene Beispiel beschränkt. Sie kann vorteilhaft auch direkt zwischen Wagenkasten und Rädern oder Radsätzen, ggf. unter Zwischenschaltung geeigneter Bauelemente an anderer Stelle angeordnet sein.The arrangement of the invention is not limited to the example described in the embodiment. It can advantageously also be arranged directly between the car body and the wheels or wheel sets, if appropriate with the interposition of suitable components at another point.
