Description

Die Erfindung betrifft ein vierachsiges Drehgestell für Niederflurwagen, mit zwei je zwei Radsätzen tragenden, H-förmigen Rahmen, die mit einem einen Querbalken bildenden und die Drehlagerung des Drehgestelles aufnehmenden Hauptträger gelenkig verbunden sind.The invention relates to a four-axle bogie for low-floor wagons, with two H-shaped frames each carrying two sets of wheels, which are connected in an articulated manner to a main beam forming a crossbeam and receiving the rotary bearing of the bogie.

Durch die DE-OS 1 605 094 ist ein Radgestell für niedrig gebaute Eisenbahnwagen bekannt geworden, bei welchem zwei H-Rahmen mittels eines gemeinsamen Gelenks verbunden und über Federn an einem Mittelquerträger abgestützt sind.From DE-OS 1 605 094 a wheel frame for low-build railway wagons has become known, in which two H-frames are connected by means of a common joint and are supported on a central cross member via springs.

Die AT-PS 305 360 zeigt ein vierachsiges Drehgestell mit zwei H-förmigen Rahmen für je zwei Achsen und einen Hauptträger, mit welchem die H-Rahmen gelenkig verbunden sind. Bei dieser Konstruktion ist der Hauptrahmen oder Hauptträger H-förmig und umfaßt mit den Enden seiner Schenkel gelenkig die Querstege der H-Rahmen.The AT-PS 305 360 shows a four-axle bogie with two H-shaped frames for two axles each and a main beam with which the H-frames are articulated. In this construction, the main frame or main girder is H-shaped and, with the ends of its legs, articulates around the crossbars of the H-frame.

Die Erfindung hat zum Ziel, eine gleichmäßige Verteilung der Achslasten auch bei schlechtem Gleis und damit gute Laufeigenschaften zu erreichen; des weiteren soll sich das erfindungsgemäße Drehgestell mit einer mechanischen oder hydraulischen Ausgleichsvorrichtung auch für extreme Rampenfahrten und für den Fährbetrieb eignen.The aim of the invention is to achieve a uniform distribution of the axle loads even on poor track and thus good running properties; Furthermore, the bogie according to the invention with a mechanical or hydraulic balancing device should also be suitable for extreme ramp journeys and for ferry operation.

Diese Aufgabe konnte mit den bekannten Konstruktionen nicht oder nur ungenügend gelöst werden.This task could not be solved with the known constructions or only insufficiently.

Das gesteckte Ziel wird dadurch erreicht, daß bei einem Drehgestell der eingangs erwähnten Art erfindungsgemäß der Wagenaufbau mittels eines starr an ihm befestigten Tauchzapfens am Querträger gelagert ist, daß die dem Querbalken zugewendeten Enden der Längsträger der H-förmigen Rahmen um je eine horizontale Achse unmittelbar oder unter Zwischenschaltung eines zweiarmigen Hebels schwenkbar am Querbalken angelenkt sind und daß in an sich bekannter Weise der Fahrzeugaufbau an jedem Längsträger mittels jeweils einer Tragfeder abgestützt ist.The objective is achieved in that, in a bogie of the type mentioned at the outset, the vehicle body is mounted on the cross member by means of a plunger rigidly attached to it, in that the ends of the longitudinal members of the H-shaped frame facing the cross bar are each directly or horizontally about a horizontal axis with the interposition of a two-armed lever are pivotally articulated on the crossbar and that the vehicle body is supported in a manner known per se on each side member by means of a respective suspension spring.

Bei diesem Drehgestell hat sich gezeigt, daß selbst bei ungünstigen Fahrweisen keine Achsfehler entstehen, da beide Seiten des Drehgestelles gleichmäßig gebremst werden, wodurch keine einseitige Belastung entstehen kann, gleichgültig, ob die Lagerung der H-Rahmen unter Vermittlung eines zweiarmigen Hebels erfolgt oder nicht.With this bogie it has been shown that even with unfavorable driving methods there are no axle errors, since both sides of the bogie are braked evenly, which means that there can be no one-sided loading, regardless of whether the H-frame is supported by a two-armed lever or not.

In vorteilhafter Weise sind die Widerlager der in der Fahrtrichtung hintereinander gelegenen Tragfedern durch eine z.B. als Zug- oder Druckstange ausgebildete Ausgleichsvorrichtung verbunden. Hiebei könnten die Widerlager in bekannter Weise auch als Kolben hydraulischer Zylinder, die durch eine Ausgleichsleitung verbunden sind, ausgebildet sein.Advantageously, the abutments of the suspension springs located one behind the other in the direction of travel are e.g. connected as a pull or push rod compensation device. The abutments could also be designed in a known manner as pistons of hydraulic cylinders which are connected by an equalizing line.

Wohl sind mechanische und hydraulische Ausgleichsvorrichtungen bekannt. So zeigt die DE-PS Krupp 439 045 ein Untergestell für Eisenbahnwagen, bei welchem die einen Enden je zweier mit ihren anderen Enden an je einen LängsausgleichhebeLangeschlossener Achsfedern eines Radsatzpaares durch Teile derartig miteinander verbunden sind, daß eine.Mehrbelastung der einen Feder sich gleichmäßig auf beide Federn verteilt.Mechanical and hydraulic balancing devices are well known. For example, DE-PS Krupp 439 045 shows a base frame for railway carriages, in which one end each has two ends with its other ends to a longitudinal compensation lever are connected to each other so that an additional load on one spring is evenly distributed over both springs.

Weiters offenbart die AT-PS 325 663 eine Vorrichtung zum Ausgleichen der Achsdrücke an einem Fahrgestell eines Schienenfahrzeuges mit zwei wechselweise beaufschlagbaren pneumatischen oder hydraulischen Druckelementen zum Übertragen je einer im wesentlichen abwärts gerichteten Ausgleichskraft auf das vordere bzw. das hintere Ende des Fahrgestelles, wobei die beiden Druckelemente je über eine Druckleitung verbunden sind.Furthermore, AT-PS 325 663 discloses a device for balancing the axle pressures on a chassis of a rail vehicle with two alternately pressurized pneumatic or hydraulic pressure elements for transmitting a substantially downward balancing force to the front or rear end of the chassis, the two Pressure elements are each connected via a pressure line.

Schließlich zeigt die DE-OS 2 317 562 ein Schienendrehgestell, mit vier Radsätzen, von denen jeweils zwei auf beiden Fahrzeugseiten durch über Längsausgleichhebel miteinander verbundene Achsfedern am Fahrgestellrahmen abgestützt sind, wobei auf einer Fahrzeugseite die Längsausgleichhebel am Fahrgestellrahmen höhenbeweglich und über ein Hydrauliksystem ausgeglichen sind.Finally, DE-OS 2 317 562 shows a rail bogie, with four wheel sets, two of which are supported on both sides of the vehicle by axle springs connected to one another via longitudinal compensation levers on the chassis frame, the longitudinal compensation levers on the vehicle frame being vertically movable on one side of the vehicle and balanced by a hydraulic system.

Alle bekannten Konstruktionen stehen in Verbindung mit Drehgestellen anderer Bauart als das erfindungsgemäße, so daß mit den bekannten Ausbildungen andere Fahreigenschaften des Drehgestelles als mit den erfindungsgemäßen Vorschlägen erzielt werden.All known constructions are in connection with bogies of a different type than the one according to the invention, so that different driving properties of the bogie than with the proposals according to the invention are achieved with the known designs.

Weitere Merkmale der Erfindung werden im folgenden an Hand der Zeichnungen erläutert, welche drei Ausführungsbeispiele des erfindungsgemäßen Drehgestelles veranschaulichen. Es zeigen

Der Hauptquerträger des Drehgestelles ist mit 1 bezeichnet und besteht aus einem kastenartigen Tragteil 2, der in seiner Mitte mit einer Ausnehmung 3 zur Aufnahme einer nicht gezeigten Lagerung für den am Wagenaufbau starr befestigten Tauchzapfen versehen ist. Diese Tauchzapfen-Lagerung besteht im wesentlichen aus einer Hülse, in welche der Tauchzapfen axial verschiebbar paßt, einer kugelförmigen, auf der Hülse sitzenden Verdickung und einer diese kugelförmige Verdickung aufnehmenden Halterung, die in der Ausnehmung 3 befestigt wird. Diese Lagerung kann sich in einem Ölbad befinden und ist daher wartungsfrei. Der Hauptträger 1 kann sich daher gegenüber dem Tauchzapfen axial, d.h. vertikal, verschieben, verdrehen und nach jeder Richtung schräg stellen.The main cross member of the bogie is designated 1 and consists of a box-like support part 2, which is provided in its center with a recess 3 for receiving a bearing, not shown, for the plunger rigidly attached to the car body. This plunger bearing essentially consists of a sleeve in which the plunger fits axially displaceably, a spherical thickening seated on the sleeve and a holder receiving this spherical thickening which is fastened in the recess 3. This storage can be in an oil bath and is therefore maintenance-free. The main carrier 1 can therefore move axially, ie vertically, shift, twist and obliquely in any direction relative to the plunger put.

An jedem Ende des kastenartigen Tragteils 2 sind bei den Ausführungsformen des Drehgestelles nach den Figuren 1 und 2 sowie 4 und 5 zwei mit diesem starr verbundene bzw. von diesem ausgehende Fortsätze 4 vorgesehen, an welchen die H-förmigen Rahmen 5 an den dem Haupt-Querträger 1 zugekehrten Enden ihrer Längsteile 8 um horizontale Achsen 6 schwenkbar angelenkt sind.In the embodiments of the bogie according to FIGS. 1 and 2 and 4 and 5, two extensions 4 rigidly connected to or extending from this are provided at each end of the box-like support part 2, on which the H-shaped frames 5 on the main Cross member 1 facing ends of their longitudinal parts 8 are pivoted about horizontal axes 6.

Diese Rahmen 5 bestehen aus einem als Kastenträger ausgebildeten Querteil 7 und den Längsteilen 8, die mit je zwei Ausnehmungen 9 zur Aufnahme der die Achsstummel 10 der Radsätze 11 haltenden Achslager - nicht gezeigt - versehen sind. Bei der Ausführungsform des Drehgestelles nach den Figuren 1 und 2 ist an der übergangsstelle zwischen Querteil 7 und jedem Längsteil 8 eine topfartige, oben offene Ausnehmung 12 vorgesehen, deren quer zur Fahrtrichtung gelegene Mittelebene mit der Längsmittelebene des Querteiles 7 vorzugsweise zusammenfällt; in diesen Ausnehmungen befinden sich die noch zu beschreibenden Federn samt Unterstützungen. Die H-förmigen Rahmen 5 haben auf Grund ihrer Form und auch durch ihre Dimensionierung eine gewisse Verwindungsfähigkeit, von welcher beim erfindungsgemäßen Drehgestell bewußt Gebrauch gemacht wird.These frames 5 consist of a cross member 7 designed as a box girder and the longitudinal parts 8, which are each provided with two recesses 9 for receiving the axle journals 10 of the wheel sets 11 - not shown. In the embodiment of the bogie according to FIGS. 1 and 2, a pot-like recess 12 open at the top is provided at the transition point between the transverse part 7 and each longitudinal part 8, the central plane of which is transverse to the direction of travel preferably coinciding with the longitudinal central plane of the transverse part 7; The springs to be described, including supports, are located in these recesses. The H-shaped frame 5 have due to their shape and also by their dimensioning a certain ability to twist, which is consciously used in the bogie according to the invention.

Die nicht gezeigten Achslager für die Achsstummel 10 sind an der Oberseite 13 der Ausnehmung 9 durch Gummiplatten abgestützt und können daher geringfügige Vertikal- sowie Schwenkbewegungen gegenüber dem Rahmen 5 ausführen, wenn sich dieser infolge von Gleisunebenheiten verwindet.The axle bearings (not shown) for the stub axles 10 are supported on the top 13 of the recess 9 by rubber plates and can therefore perform slight vertical and pivoting movements relative to the frame 5 if the frame twists as a result of unevenness in the track.

Zur Abfederung des nur angedeuteten Wagenaufbaues 14 sind an jedem Drehgestell vier Tragfedern 15 vorgesehen. Diese sind als Schraubenfedern ausgebildet und können in üblicher Weise durch Ineinander- oder Hintereinander-Anordnen zweier Schraubenfedern mit verschiedener Kennlinie und verschiedener Länge, gegebenenfalls durch Zwischenschalten eines Blockiertopfes, in bevorzugter Weise eine nichtlineare oder progressive Gesamtkennlinie haben. Die Oberseite jeder Feder 15 ist mit einer Tragplatte 16 versehen, die über einen daran befestigten Gleitbelag 17 die Unterseite des Wagenaufbaues 14 trägt.Four suspension springs 15 are provided on each bogie to cushion the car body 14, which is only indicated. These are designed as helical springs and can preferably have a non-linear or progressive overall characteristic curve in the usual manner by arranging two helical springs with different characteristics and different lengths, one inside the other or one behind the other, if necessary by interposing a blocking pot. The top of each spring 15 is provided with a support plate 16 which supports the underside of the carriage structure 14 via a sliding coating 17 attached to it.

Bei der Ausführungsform des Drehgestells nach den Figuren 4 und 5 sind zur Führung der Federn 15 nur angedeutete Bolzen 18 vorgesehen, die am Boden der Ausnehmungen 12 befestigt sind und nach oben ragen.In the embodiment of the bogie according to FIGS. 4 and 5, only indicated bolts 18 are provided for guiding the springs 15, which are fastened to the bottom of the recesses 12 and project upwards.

Bei der Ausführungsform nach Figur 3 ist an Stelle der beiden Fortsätze 4 mindestens an einem Ende des Hauptquerträgers 1 ein doppelarmiger Hebel 4' vorgesehen, welcher mit dem Tragteil 2 gelenkig verbunden ist bzw. auf diesem um eine in der Längsmittelebene des Hauptquerträgers 1 gelegene Längsachse 2' schwenkbar gelagert ist. Auf den Enden dieser Hebel 4' sind über Silent Blocks die Längsteile 8 der Querteile 7 schwenkbar gelagert.In the embodiment according to FIG. 3, instead of the two extensions 4, a double-armed lever 4 'is provided at least at one end of the main cross member 1, which is articulated to the support part 2 or on the latter about a longitudinal axis 2 located in the longitudinal center plane of the main cross member 1 'is pivoted. On the ends of these levers 4 ', the longitudinal parts 8 of the transverse parts 7 are pivotally mounted via silent blocks.

Bei der Ausführungsform des Drehgestells nach den Figuren 4 und 5 sind die Federn 15 an ihrer Unterseite mit je einer Tragplatte 19 versehen, welche ihrerseits auf dem freien Ende eines Stützhebels 20 aufliegt. Das Ende dieses Stützhebels ist gegabelt und umfaßt den Bolzen 18. Wie in Figur 4 des weiteren zu erkennen ist, haben die Enden der Stützhebel 20 gewölbte Oberseiten 21, sodaß sie sich bei ihren Schwenkbewegungen an der Unterseite der Tragplatte 19 ohne jede Reibung abwälzen können.In the embodiment of the bogie according to FIGS. 4 and 5, the springs 15 are each provided on their underside with a support plate 19, which in turn rests on the free end of a support lever 20. The end of this support lever is bifurcated and comprises the pin 18. As can also be seen in FIG. 4, the ends of the support lever 20 have domed tops 21 so that they can roll on the underside of the support plate 19 during their pivoting movements without any friction.

Die Stützhebel 20 sind an je einer kurzen Welle 22 befestigt, die in den beiden Wänden der topfartigen Ausnehmung 12 drehbar gelagert sind. Die zu beiden Seiten jedes H-förmigen Rahmens 5 angebrachten Wellen haben eine gemeinsame horizortale Achse 22' , welche in einer mittleren Vertikalebene des Trägers 7 verläuft, die zu den Achsen der beiden Radsätze 11 des H-förmigen Rahmens 5 vorzugsweise gleichen Abstand hat (vgl. insbes. Figur 4 links). Ein Ende jeder Welle 22 ist über die Außenwand des Längsteiles 8 hinaus verlängert und trägt dort einen Ausgleichshebel 23. Die beiden an der gleichen Drehgestellseite befindlichen Ausgleichshebel 23 sind in der Zeichnung nach oben hin zueinander geneigt angeordnet und durch eine Ausgleichsvorrichtung miteinander gekoppelt. Sie können aber auch vorzugsweise lotrecht und parallel zueinander angeordnet sein.The support levers 20 are each attached to a short shaft 22, which is rotatably mounted in the two walls of the pot-like recess 12. The shafts attached to both sides of each H-shaped frame 5 have a common horizontal axis 22 ', which runs in a central vertical plane of the carrier 7, which is preferably at the same distance from the axes of the two wheel sets 11 of the H-shaped frame 5 (cf. especially Figure 4 left). One end of each shaft 22 is extended beyond the outer wall of the longitudinal part 8 and carries a compensating lever 23 there. The two compensating levers 23 located on the same bogie side are inclined upwards in the drawing and are coupled to one another by a compensating device. However, they can also preferably be arranged perpendicularly and parallel to one another.

Beim gezeigten Ausführungsbeispiel besteht diese Ausgleichsvorrichtung aus je einer Zugstange 24, welche mit ihren Enden an die Ausgleichshebel 23 über Bolzen 25 gelenkig angeschlossen ist. Jeweils zwischen den Zugstangen 24 oder einen der beiden Ausgleichshebel 23 und die Seitenwandung des Drehgestells kann ein Schwingungsdämpfer gelegt sein; vorteilhafterweise werden diese Schwingungsdämpfer, im wesentlichen horizontal liegend, jeweils zwischen den Zugstangen 24 und den Enden des Haupt-Querträgers 1 angelenkt.In the exemplary embodiment shown, this compensation device consists of a pull rod 24, which is connected at its ends to the compensation lever 23 via bolts 25 in an articulated manner. A vibration damper can be placed between the tie rods 24 or one of the two compensating levers 23 and the side wall of the bogie; These vibration dampers, lying essentially horizontally, are each articulated between the tie rods 24 and the ends of the main cross member 1.

Selbstverständlich kann im Rahmen der Erfindung an Stelle der Zugstange 24, wie Figur 6 zeigte -ine Druckstange 24' treten. Zu diesem Zwecke sind die .Tragfedern 15 nicht wie in den Figuren 4 und 5 dargestellt, zwischen dem dem Hebel 23 und dem äußeren, sondern wie Figur 6 zeigt, dem benachbarten inneren Radsatz 11 angeordnet, wobei die Hebel 23 nach oben auseinander laufen können. Durch diese Konstruktion wird der-Abstand zwischen Drehzapfen und Gleitplatte geringer, wodurch die Rückstellkraft in der Gleitplattenabstützung herabgesetzt wird.Of course, in the context of the invention, instead of the pull rod 24, as shown in FIG Push push rod 24 '. For this purpose, the suspension springs 15 are not arranged as shown in FIGS. 4 and 5, between the lever 23 and the outer one, but, as shown in FIG. 6, the adjacent inner wheel set 11, wherein the levers 23 can diverge upwards. This construction reduces the distance between the pivot pin and the slide plate, which reduces the restoring force in the slide plate support.

Die Wirkungsweise der beschriebenen Ausgleichsvorrichtung wird im folgenden an Hand der Figuren 7 und 8 erläutert.The operation of the compensation device described is explained below with reference to Figures 7 and 8.

Gemäß Figur 7 haben zwei Achsen des Drehgestells den Beginn (Punkt A) einer Rampe B bereits überfahren (Fahrtrichtung Pfeil B). Dadurch haben sich die beiden Achsen des in Figur 7 rechten H-förmigen Rahmens um die Beträge a1 und a2 gehoben. Damit heben sich aber auch die Berührungsstellen zwischen den Stützhebeln 20 und den Tragplatten 19 der Federn 15' dieses Rahmens an, d.h. die beiden vorderen Federn 15' dieses Rahmens müßten stärker zusammengedrückt werden. Die Kraft, mit der diese Federn auf ihre Stützhebel 20 drücken, wird größer. An den Kräfteverhältnissen bei den anderen Federn 15" (Figur 6 links) hat sich aber noch nichts geändert. Weil daher auf die Stützhebel 20 der Federn 15' eine größere Kraft als auf die Stützhebel der anderen Federn 15" wirkt, werden sich beide Stützhebelpaare, verbunden durch die Zugstangen 24, im Uhrzeigersinne soweit verschwenken, bis alle vier Federn der beiden H-förmigen Rahmen mit gleicher Kraft auf ihre Stützhebel einwirken. Durch die Anordnung der Achsen der Wellen 22 vorzugsweise in der Mitte zwischen den Radsätzen 11 jedes H-Rahmens 5 werden beide Radsätze gleich stark belastet.According to FIG. 7, two axles of the bogie have already passed the start (point A) of a ramp B (direction of travel arrow B). As a result, the two axes of the H-shaped frame on the right in FIG. 7 have been raised by the amounts a 1 and a 2 . But this also raises the points of contact between the support levers 20 and the support plates 19 of the springs 15 'of this frame, ie the two front springs 15' of this frame would have to be compressed more. The force with which these springs press on their support levers 20 increases. Nothing has yet changed in the force relationships in the other springs 15 "(FIG. 6 left). Because therefore a greater force acts on the support levers 20 of the springs 15 'than on the support levers of the other springs 15", both pairs of support levers connected by the tie rods 24, pivot clockwise until all four springs of the two H-shaped frames act on their support levers with the same force. By arranging the axes of the shafts 22 preferably in the middle between the wheel sets 11 of each H-frame 5 both wheelsets are loaded equally.

In Fig. 8 ist jene Stellung des Drehgestells gezeigt, in welcher sich die erste Achse des Drehgestells um den Betrag a3 gehoben und seine letzte Achse den Beginn A der Rampe B gerade erreicht hat. Es ist gut zu erkennen, daß sich, weil auch der linke H-Rahmen angehoben ist, die Ausgleichshebel 23 noch etwas weiter im Uhrzeigersinn verschwenkt haben. Es ist aberrauch zu sehen, daß die Längen der Federn 15' und 15" einander gleich geblieben sind. Die beim Auffahren auf die Rampe B eingetretene Neigung des Tragteils 2 gegenüber der Horizontalen (vgl. den Verlauf der Geraden zwischen den Achsen 6 in Figur 7) und damit die Schrägstellung des Hauptquerträgers 1 gegenüber dem im wesentlichen vertikal bleibenden Tauchzapfen wird durch die eingangs beschriebene kugelgelenksartige Halterung der den Tauchzapfen aufnehmenden Hülse in der Ausnehmung 3 ausgeglichen.8 shows that position of the bogie in which the first axis of the bogie has increased by the amount a 3 and its last axis has just reached the start A of the ramp B. It can be clearly seen that, because the left H frame is also raised, the compensating levers 23 have pivoted a little further clockwise. It can be seen, however, that the lengths of the springs 15 'and 15 "have remained the same. The inclination of the support part 2 with respect to the horizontal when the ramp B is approached (cf. the course of the straight line between the axes 6 in FIG. 7) ) and thus the inclination of the main cross member 1 with respect to the essentially vertical plunger is compensated for by the above-described ball-and-socket mounting of the sleeve receiving the plunger in the recess 3.

Anstelle der Zug- bzw. Druckstange 24 kann auch eine hydraulische Ausgleichsvorrichtung vorgesehen werden. Dabei ist jeder Ausgleichshebel übereiren vorzugsweise auf Druck beanspruchten Lenker mit der Stange eines Kolbens verbunden, der sich in einem im wesentlichen horizontalen, am H-förmigen Träger befestigten Zylinder verschieben kann. Die Zylinder sind einer, ends verschlossen und mit einer Flüssigkeit (Hydrauliköl u.dgl.) gefüllt. Die zwei Zylinder jeder Drehgestellseite sind durch eine druckfeste Leitung miteinander verbunden.Instead of the pull or push rod 24, a hydraulic compensation device can also be provided. Each compensating lever is connected to the rod of a piston, which can be moved in a substantially horizontal cylinder attached to the H-shaped support, preferably under pressure. The cylinders are closed at one end and filled with a liquid (hydraulic oil and the like). The two cylinders on each side of the bogie are connected by a pressure-resistant line.

Es besteht auch die Möglichkeit, die Tragplatte 19 als Kolben eines Zylinders auszubilden und beide einander quer zur Fahrtrichtung gelegenen Zylinderpaare mit einer Öldruckleitung zu verbinden, wobei die mechanische Ausgleichsvorrichtung entfällt.There is also the possibility of designing the support plate 19 as a piston of a cylinder and of both cylinders lying at right angles to the direction of travel To connect pairs with an oil pressure line, the mechanical balancing device is omitted.

Die Wirkungsweise dieser hydraulischen Ausgleichsvorrichtungen ist jener der mechanischen Ausgleichsvorrichtungen - mit Zugstange - gleich.The operation of these hydraulic balancing devices is the same as that of the mechanical balancing devices - with tie rod.

In der die beiden Zylinder verbindenden Druckleitung kann eine Drosselstelle, etwa in Form eines Ventils, vorgesehen sein, um Schwingungen, die bei schlechten Gleisen auftreten können, zu dämpfen.A throttling point, for example in the form of a valve, can be provided in the pressure line connecting the two cylinders in order to dampen vibrations which can occur on poor tracks.
