Description

Die Erfindung bezieht sich auf ein selbstlenkendes, dreiachsiges Laufgestell mit Lenkbalken gemäß dem Oberbegriff der nebengeordneten Ansprüche 1 und 4.The invention relates to a self-steering, three-axle bogie with steering beam according to the preamble of the independent claims 1 and 4.

Ein solches selbstlenkendes, dreiachsiges Laufgestell mit Lenkbalken ist aus der DE 38 24 709 C2 bekannt. Dort wird ein Eisenbahnfahrzeug mit einem durch ein Laufgestell mit mindestens zwei Rad/Achsen-Anordnungen abgestützten Wagenkasten beschrieben, wobei das Laufgestell einen Laufgestellrahmen mit zwei parallelen Seitenträgern enthält, die durch mindestens einen sich quer dazu erstreckenden Querbalken verbunden sind und der Laufgestellrahmen von den Achsen durch Primärfederungsmittel getragen ist, die Gier-Bewegungen zum Lauf längs eines gekrümmten Gleises zulassen. Ein erstes Kraftübertragungsgestänge verbindet die Achsen mit dem Laufgestellrahmen und enthält mindestens einen querverlaufenden Lenkbalken, der mit einer Achse verbunden ist und ein schwenkbar mit dem Laufgestellrahmen verbundenes Zentrum besitzt, um ein Lenken der damit verbundenen Achse zur Verbesserung ihrer Radialstellung und eine Übertragung von Längskräften zwischen ihr und dem Laufgestellrahmen zu ermöglichen.Such a self-steering, three-axle bogie with steering beam is known from DE 38 24 709 C2. There, a railroad vehicle is described with a car body supported by a bogie with at least two wheel / axle arrangements, the bogie containing a bogie frame with two parallel side members, which are connected by at least one transverse beam extending transversely thereto and the bogie frame from the axles Primary suspension means is carried, which allow yawing movements to run along a curved track. A first transmission linkage connects the axles to the bogie frame and includes at least one transverse steering beam which is connected to an axle and has a pivotally connected center to the bogie frame to steer the associated axle to improve its radial position and to allow transmission of longitudinal forces between it and the bogie frame.

Eine Kraftübertragungsanordnung verbindet den Laufgestellrahmen mit dem Wagenkasten. Die Kraftübertragungsanordnung ist als ein zweites Kraftübertragungsgestänge mit Pfosten, Platte und Stab ausgebildet, das folgende Merkmale aufweist:

  • a) einen am Wagenkasten in Seitenrichtung zwischen den Seitenträgern und in Längsrichtung benachbart zu dem mindestens einen Querbalken angeordneten und von dem Wagenkasten nach unten abstehenden Wagenkastenpfosten,
  • b) eine schwenkbar an dem Wagenkastenpfosten gehaltene Wagenkastenplatte mit seitlich einander gegenüberliegenden Schwenkstellen, die jeweils zwischen dem Wagenkastenpfosten und einem der Seitenträger angeordnet sind, und
  • c) bewegbar angebrachte Verbindungsstäbe, die in Längsrichtung jede Schwenkstelle an der Wagenkastenplatte mit dem benachbarten Querträger verbinden, um Zug- und Bremskräfte zu übertragen und Gier- und Seitenbewegungen des Wagenkastens relativ zum Laufgestellrahmen zuzulassen.
A power transmission assembly connects the bogie frame to the body. The power transmission arrangement is designed as a second power transmission linkage with post, plate and rod, which has the following features:
  • a) a car body post arranged on the car body in the lateral direction between the side supports and in the longitudinal direction adjacent to the at least one crossbeam and projecting downward from the car body,
  • b) a car body plate pivotally held on the car body post with laterally opposite pivot points which are each arranged between the car body post and one of the side members, and
  • c) movably attached connecting rods that connect each pivot point on the body plate with the adjacent cross member in the longitudinal direction to transmit tensile and braking forces and allow yaw and lateral movements of the body relative to the bogie frame.

In weiterer Ausgestaltung dieses bekannten Eisenbahnfahrzeuges ist der Wagenkasten an dem Laufgestellrahmen durch elastische Sekundärfederungsmittel abgestützt, die seitlich beabstandet in Richtung auf gegenüberliegende Seiten des Laufgestellrahmens angeordnet sind, wobei das Laufgestell mindestens drei Rad/Achsen-Anordnungen enthält.In a further embodiment of this known railway vehicle, the car body is supported on the bogie frame by elastic secondary spring means, which are arranged laterally spaced in the direction of opposite sides of the bogie frame, the bogie containing at least three wheel / axle arrangements.

Der Laufgestellrahmen weist zwei Querbalken der genannten Art auf, die jeweils zwischen einer Endachse und den restlichen Achsen mit Abstand angeordnet sind. Das erste Kraftübertragungsgestänge enthält zwei Lenkbalken, die jeweils einzeln mit jeder Endachse verbunden sind, und Verbindungsmittel, die die Lenkbalken so verbinden, daß Selbstlenk-Gier-Bewegungen der Rad/Achsen-Anordnungen einander entgegengesetzt gleich sind. Die Verbindungsmittel weisen folgende Merkmale auf:

  • a) ein von jedem Lenkbalken nach oben abstehendes und schwenkbar an einem der Querbalken angebrachtes Drehmomentrohr mit einem oberhalb des jeweiligen Lenkbalkens angeordneten Hebel, wobei sich die Hebel quer in entgegengesetzte Richtungen erstrecken und
  • b) eine die beiden Hebel zu gleichen, entgegengesetzt gerichteten Schwenkbewegungen verbindende Stange, die sich zur Verbindung der Lenkbalken diagonal über einen Abschnitt zwischen den Querbalken erstreckt.
The bogie frame has two crossbeams of the type mentioned, which are each spaced between an end axis and the remaining axes. The first transmission linkage contains two steering beams, each are individually connected to each end axle, and connecting means connecting the steering beams so that self-steering yaw motions of the wheel / axle assemblies are opposite to each other. The connecting means have the following features:
  • a) a torque tube protruding upwards from each steering beam and pivotably attached to one of the crossbars with a lever arranged above the respective steering beam, the levers extending transversely in opposite directions and
  • b) a rod connecting the two levers to the same, oppositely directed pivoting movements, which extends diagonally to connect the steering beams over a section between the transverse beams.

Der Erfindung liegt die Aufgabe zugrunde, ein selbstlenkendes, dreiachsiges Laufgestell mit Lenkbalken der eingangs genannten Art anzugeben, bei dem auch der Mittelradsatz an dem Steuerungssystem beteiligt ist.The invention has for its object to provide a self-steering, three-axle bogie with steering beams of the type mentioned, in which the center wheel set is also involved in the control system.

Diese Aufgabe wird alternativ in Verbindung mit den Merkmalen des Oberbegriffes erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 und 4 angegebenen Merkmale gelöst.This object is alternatively achieved in connection with the features of the preamble according to the invention by the features specified in the characterizing part of claims 1 and 4.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß ein selbstlenkendes, dreiachsiges Laufgestell für ein Schienenfahrzeug geschaffen wird, bei dem alle drei Radsätze zur Steuerung bei Kurvenfahrt herangezogen werden, und das nur relativ wenig Teile erfordert.The advantages that can be achieved with the invention are, in particular, that a self-steering, three-axle bogie for a rail vehicle is created, in which all three wheel sets are used for control when cornering, and that requires only relatively few parts.

Durch die aktive Mitwirkung des Mittelradsatzes am Steuerungssystem werden die der Steuerbewegung entgegenstehenden horizontalen Federauslenkkräfte der Radsatzfedern leichter überwunden und insbesondere bei kleinen Bogenradien, bei denen für die radiale Stellung größere horizontale Auslenkungen der Radsatzfedern erforderlich werden, wird die Ausrichtung der Radsatzwelle zur Bogenmitte verbessert.Through the active participation of the center wheel set on the control system, the horizontal spring deflection forces of the wheel set springs opposing the control movement are more easily overcome, and in particular in the case of small radii of curvature, in which larger horizontal deflections are required for the radial position If the wheelset springs are required, the alignment of the wheelset shaft to the center of the bow is improved.

Die Erfindung wird nachstehend anhand der in der Zeichnung dargestellten Ausführungsbeispiele erläutert.The invention is explained below with reference to the embodiments shown in the drawing.

Es ist ein dreiachsiges Laufgestell für ein Schienenfahrzeug zu erkennen, das einen nicht dargestellten, aus Längs- und Querträgern bestehenden Laufgestellrahmen aufweist. An den Längsträgern sind Radsatzlagergehäuse 2 bis 7 der drei Radsätze 8, 9, 10 über nicht dargestellte Federelemente befestigt, und zwar Radsatzlagergehäuse 2, 3 für den ersten Radsatz 8 (= Außenradsatz), Radsatzlagergehäuse 4, 5 für den zweiten Radsatz 9 (= Mittelradsatz) und Radsatzlagergehäuse 6, 7 für den dritten Radsatz 10 (= Außenradsatz). Die Laufräder der Radsätze sind mit Ziffer 11 bezeichnet. Die Radsätze können durch nicht dargestellte Antriebsmotoren (beispielsweise Tatzlagermotoren oder Gestellmotoren) angetrieben werden.In Figure 1, a first variant of a drive with coupling via two steering beams is shown. A three-axle bogie for a rail vehicle can be seen, which has a bogie frame, not shown, consisting of longitudinal and cross members. Wheelset bearing housings 2 to 7 of the three wheel sets 8, 9, 10 are fastened to the longitudinal members via spring elements, not shown, namely wheel set bearing housings 2, 3 for the first wheel set 8 (= outer wheel set), wheel set bearing housings 4, 5 for the second wheel set 9 (= center wheel set ) and wheelset bearing housings 6, 7 for the third wheelset 10 (= outer wheelset). The wheels of the wheel sets are designated with number 11. The wheel sets can be driven by drive motors (not shown) (for example Tatzlagermotoren or rack motors).

Die Radsatzlagergehäuse 2, 3, 6, 7 der beiden Außenradsätze 8, 10 sind unter anderem in Fahrtrichtung bzw. entgegengesetzt zur Fahrtrichtung des Schienenfahrzeuges beweglich, was durch Richtungspfeile x1, x2 jeweils angedeutet ist. Die Radsatzlagergehäuse 4, 5 des Mittelradsatzes 9 sind unter anderem senkrecht zur Fahrtrichtung des Schienenfahrzeuges beweglich, was durch Richtungspfeile y1, y2 jeweils angedeutet ist.The wheelset bearing housings 2, 3, 6, 7 of the two outer wheel sets 8, 10 can be moved, inter alia, in the direction of travel or opposite to the direction of travel of the rail vehicle, which is indicated by directional arrows x1, x2. The wheelset bearing housings 4, 5 of the center wheel set 9 can be moved, inter alia, perpendicular to the direction of travel of the rail vehicle, which is indicated by directional arrows y1, y2.

Zur Steuerung des Laufwerks bei Kurvenfahrt sind zwei Lenkbalken 12 bzw. 13 mit jeweils rahmenfester Schwenkachse 14 bzw. 15 (Vertikalachse) vorgesehen. Diese Schwenkachsen 14, 15 befinden sich jeweils auf der Fahrzeuglängsmitte. In jeweils gleichem Abstand beidseitig zu der Schwenkachse eines jeden Lenkbalkens sind Gelenke 16 vorgesehen, die zur Kopplung der einzelnen Radsatzlagergehäuse der Außenradsätze über Lenkerstangen mit den Lenkbalken dienen. Im einzelnen sind Radsatzlagergehäuse 2 über eine Lenkerstange 17 mit dem Lenkbalken 12, Radsatzlagergehäuse 3 über eine Lenkerstange 18 mit dem Lenkbalken 12, Radsatzlagergehäuse 6 über eine Lenkerstange 19 mit dem Lenkbalken 13 und Radsatzlagergehäuse 7 über eine Lenkerstange 20 mit dem Lenkbalken 13 verbunden. Die Gelenke zur Befestigung der Lenkerstangen mit den Radsatzlagergehäusen sind mit Ziffer 21 bezeichnet.To control the drive when cornering, two steering beams 12 and 13 are provided, each with fixed frame pivot axis 14 and 15 (vertical axis). These pivot axes 14, 15 are each located on the longitudinal center of the vehicle. At the same distance on both sides of the pivot axis of each steering beam, joints 16 are provided, which are used to couple the individual wheel set bearing housings of the outer wheel sets via handlebars to the steering beams. Specifically, wheelset bearing housings 2 are connected to the steering beam 12 via a handlebar 17, wheelset bearing housings 3 are connected to the steering beam 12 via a steering rod 18, wheelset bearing housings 6 are connected to the steering beam 13 via a handlebar 19, and wheelset bearing housings 7 are connected to the steering beam 13 via a handlebar 20. The joints for attaching the handlebars to the wheelset bearing housings are marked with number 21.

Die Kopplung zwischen den Lenkbalken und den Radsatzlagergehäusen des Mittelradsatzes erfolgt über Lenkerstangen 22 und Winkelhebel 26, 27, wobei die Gelenke zur Verbindung der Lenkerstangen mit den Lenkbalken mit Ziffer 24 und die Gelenke zur Verbindung der Lenkerstangen mit den ersten Armen der Winkelhebel mit Ziffer 25 bezeichnet sind. Die Gelenke 24 weisen einen größeren Abstand zur Fahrzeuglängsmitte auf als die Gelenke 16. Die Winkelhebel haben rahmenfeste Drehachsen 28 und sind über Gelenke 29 über ihre zweiten Arme mit den Stirnseiten der Radsatzlagergehäuse des Mittelradsatzes verbunden. Im einzelnen ergibt sich eine Kopplung vom Lenkbalken 12 über die Lenkerstange 22 und den Winkelhebel 26 zum Radsatzlagergehäuse 5 sowie eine Kopplung vom Lenkbalken 13 über die Lenkerstange 23 und den Winkelhebel 27 zum Radsatzlagergehäuse 4.The coupling between the steering beam and the wheelset bearing housings of the center wheel set is carried out via handlebar rods 22 and angle levers 26, 27, the joints for connecting the handlebar rods to the steering beams being numbered 24 and the joints for connecting the handlebar rods to the first arms of the angle levers being numbered 25 are. The joints 24 are at a greater distance from the longitudinal center of the vehicle than the joints 16. The angle levers have axes of rotation 28 fixed to the frame and are connected via joints 29 via their second arms to the end faces of the wheel set bearing housings of the center wheel set.

Während sich die Lenkbalken 12, 13 der Variante gemäß Figur 1 jedoch außerhalb der Radsätze 8, 10 befinden, sind die Lenkbalken 12' bzw. 13' bei der Variante gemäß Figur 2 zwischen den Radsätzen 8' und 9' bzw. 9' und 10' angeordnet.In principle, the same components as described in FIG. 1 are present in the second variant of a drive shown in FIG. 2 with a coupling via two steering beams. The components are each identified by simple deletions, that is, bogies 1 ', wheelset bearing housings 2' to 7 ', wheelsets 8' to 10 ', wheels 11', steering beams 12 ', 13', swivel axes 14 ', 15', joints 16 ', handlebars 17 'to 20', joints 21 ', handlebars 22', 23 ', joints 24', 25 ', angle lever 26', 27 ', axis of rotation 28', joint 29 ', trailing arms 30', 31 'and joints 32', 33 '. However, while the steering beams 12, 13 of the variant according to FIG. 1 are located outside the wheel sets 8, 10, the steering beams 12 'and 13' in the variant according to FIG. 2 are between the wheel sets 8 'and 9' or 9 'and 10 'arranged.

Entsprechend sind die Lenkerstangen 22' bzw. 23' zwischen Lenkbalken 12' und Winkelhebel 26' bzw. zwischen Lenkbalken 13' und Winkelhebel 27' kürzer ausgebildet, als die entsprechenden Lenkerstangen 22, 23 gemäß Figur 1. Die Funktionsweise des Laufgestells 1 gemäß Figur 2 ist wie unter Figur 1 beschrieben.Correspondingly, the handlebars 22 'and 23' between the steering beam 12 'and the angle lever 26' or between the steering beam 13 'and the angle lever 27' are shorter than the corresponding handlebars 22, 23 according to FIG. 1 is as described in Figure 1.

In Figur 3 ist eine erste Variante eines Laufwerks mit Kopplung über lediglich einen Lenkbalken dargestellt. Die Konfiguration des Laufgestells 1'' mit Radsatzlagergehäusen 2'' bis 7'', Radsätzen 8'' bis 10'' und Laufrädern 11'' ist wie unter Figur 1 beschrieben. Das gleiche gilt für die Beweglichkeit der Radsatzlagergehäuse in x1/x2- bzw. y1/y2-Richtung. Der einzige Lenkbalken 12'' mit rahmenfester zentrischer Schwenkachse 14'' (Vertikalachse) ist über Gelenke 16'' mit den Lenkerstangen 17'' bis 18'' verbunden, die andererseits über Gelenke 21'' an den Radsatzlagergehäusen 2'' bzw. 3'' befestigt sind. Die Lenkerstange 22'' ist zwischen Gelenk 24'' des Lenkbalkens 12'' und Gelenk 25'' des Winkelhebels 26' angeordnet. Am hierzu entgegengesetzten Ende des Lenkbalkens 12'' ist der Lenkbalken im Vergleich zur Ausbildung gemäß Figur 1 verlängert, wobei an diesem verlängerten Ende ein Gelenk 40'' angeordnet ist, das zur Befestigung einer Lenkerstange 41'' dient, die andererseits zum Winkelhebel 27'' führt. Die Winkelhebel 26'' bzw. 27'' haben rahmenfeste Drehachsen 28'' und sind über Gelenke 29'' an den Radsatzlagergehäusen 5'' bzw. 4'' befestigt, im Unterschied zu Figur 1 jedoch nicht an deren Stirnseiten.FIG. 3 shows a first variant of a drive with coupling via only one steering beam. The configuration of the bogie 1 ″ with wheelset bearing housings 2 ″ to 7 ″, wheelsets 8 ″ to 10 ″ and wheels 11 ″ is as described under FIG. 1. The same applies to the mobility of the wheelset bearing housings in the x1 / x2 or y1 / y2 direction. The only steering beam 12 '' with a frame-mounted central pivot axis 14 '' (vertical axis) is connected via joints 16 '' to the handlebars 17 '' to 18 '', which on the other hand is connected via joints 21 '' to the wheelset bearing housings 2 '' or 3 are attached. The handlebar 22 ″ is arranged between the joint 24 ″ of the steering beam 12 ″ and the joint 25 ″ of the angle lever 26 ′. At the opposite end of the steering beam 12 ″, the steering beam is elongated in comparison to the design according to FIG. 1, a joint 40 ″ being arranged at this elongated end, which serves to fasten a steering rod 41 ″, which on the other hand forms an angle lever 27 ′. ' leads. The angle levers 26 ″ or 27 ″ have frame-fixed axes of rotation 28 ″ and are fastened to the wheelset bearing housings 5 ″ or 4 ″ via joints 29 ″, however, in contrast to FIG. 1, not on the end faces thereof.

Die Kopplung der weiteren Radsatzlagergehäuse 6'', 7'' mit den Radsatzlagergehäusen 4'', 5'' erfolgt nicht wie bei der Anordnung gemäß Figur 1 unter Einsatz eines eigenen Lenkbalkens, sondern über Lenkerstangen-Drehhebel-Konfigurationen. Dem Radsatzlagergehäuse 7'' ist ein Drehhebel 35'' mit rahmenfester zentrischer Drehachse 38'' zugeordnet, wobei die zum Radsatzlagergehäuse 7'' führende Lenkerstange 20'' am ersten Gelenk 39'' dieses Drehhebels angreift und das zweite Gelenk 37'' dieses Drehhebels mit einer Lenkerstange 34'' verbunden ist, die andererseits zum bereits erwähnten Gelenk 25'' des Winkelhebels 26'' führt. In gleicher Art und Weise ist dem Radsatzlagergehäuse 6'' ein Drehhebel 36'' zugeordnet, an dessen erstem Gelenk die zum Radsatzlagergehäuse 6'' führende Lenkerstange 19'' angreift und mit dessen zweiten Gelenk eine Lenkerstange 42'' verbunden ist, die zum Winkelhebel 27'' führt.The coupling of the further wheelset bearing housings 6 ″, 7 ″ to the wheelset bearing housings 4 ″, 5 ″ does not take place, as in the arrangement according to FIG. 1, using a separate steering beam, but rather via handlebar-rod-rotary lever configurations. The wheelset bearing housing 7 '' is assigned a rotary lever 35 '' with a frame-fixed central axis of rotation 38 '', whereby the handlebar rod 20 '' leading to the wheelset bearing housing 7 '' engages the first joint 39 '' of this rotary lever and the second joint 37 '' of this rotary lever is connected to a handlebar rod 34 '' which, on the other hand, forms the already mentioned joint 25 '' of the angle lever 26 '' leads. In the same way, the wheel set bearing housing 6 ″ is assigned a rotary lever 36 ″, on the first joint of which the handlebar rod 19 ″ leading to the wheel set bearing housing 6 ″ engages and on the second joint of which a steering rod 42 ″ is connected, which forms the angle lever 27 '' leads.

Auf diese Weise ergibt sich eine bezüglich der Fahrzeuglängsmitte symmetrische Anordnung mit nur einem Lenkbalken.In this way, there is a symmetrical arrangement with respect to the longitudinal center of the vehicle with only one steering beam.

Nachfolgend wird die Funktionsweise des selbstlenkenden, dreiachsigen Laufgestells 1 gemäß Figur 3 beschrieben. Durch die Konfiguration Radsatzlagergehäuse 2'', 3'', 6'', 7'' mit Gelenken 21'' - Lenkerstangen 17'', 18'', 19'', 20'' - Lenkbalken 12'' bzw. Drehhebel 35'', 36'' - Lenkerstangen 22'', 34'', 41'', 42'' - Winkelhebel 26'', 27'' - Radsatzlagergehäuse 4'', 5'' mit Gelenken 29'' ergibt sich in Verbindung mit den in Fahrtrichtung/entgegengesetzt zur Fahrtrichtung (x1,x2) des Schienenfahrzeuges beweglichen Radsatzlagergehäusen 2'', 3'', 6'', 7'' der Außenradsätze 8'', 10'' und den senkrecht zur Fahrtrichtung (y1, y2) beweglichen Radsatzlagergehäuse 4'', 5'' eine gegenläufige Kopplung der Außenradsätze bei Kurvenfahrt des Fahrzeuges. Bewegt sich beispielsweise das Radsatzlagergehäuse 2'' in Richtung x2, so müssen sich zwangsläufig das Radsatzlagergehäuse 6'' in Richtung x1 und das Radsatzlagergehäuse 4'' in Richtung y1 bewegen. Gleichzeitig bewegen sich das Radsatzlagergehäuse 3'' in Richtung x1, das Radsatzlagergehäuse 7'' in Richtung x2 und das Radsatzlagergehäuse 5'' in Richtung y1.The mode of operation of the self-steering, three-axle bogie 1 according to FIG. 3 is described below. Due to the configuration of the axlebox bearing housing 2 '', 3 '', 6 '', 7 '' with joints 21 '' - handlebars 17 '', 18 '', 19 '', 20 '' - steering beam 12 '' or rotary lever 35 '', 36 '' - handlebars 22 '', 34 '', 41 '', 42 '' - angle lever 26 '', 27 '' - wheelset bearing housing 4 '', 5 '' with joints 29 '' results in connection with the wheelset bearing housings 2 '', 3 '', 6 '', 7 '' of the outer wheel sets 8 '', 10 '' movable in the direction of travel / opposite to the direction of travel (x1, x2) of the rail vehicle and perpendicular to the direction of travel (y1, y2 ) movable wheelset bearing housing 4 '', 5 '' an opposite coupling of the outer wheel sets when cornering the vehicle. For example, if the wheelset bearing housing 2 ″ moves in the x2 direction, the wheelset bearing housing 6 ″ inevitably has to move in the x1 direction and the wheelset bearing housing 4 ″ in the y1 direction. At the same time, the wheelset bearing housing 3 ″ move in the x1 direction, the wheelset bearing housing 7 ″ in the x2 direction and the wheelset bearing housing 5 ″ in the y1 direction.

Während sich der Lenkbalken 12'' der Variante gemäß Figur 3 jedoch außerhalb des Radsatzes 8'' befindet, ist der Lenkbalken 12''' bei der Variante gemäß Figur 4 zwischen den Radsätzen 8''' und 9''' angeordnet. Entsprechend sind die Lenkerstangen 22''' bzw. 41''' zwischen Lenkbalken 12''' und Winkelhebel 26''' bzw. zwischen Lenkbalken 12''' und Winkelhebel 27''' kürzer ausgebildet als die entsprechenden Lenkerstangen 22'', 41'' gemäß Figur 3. Die Funktionsweise des Laufgestells 1''' ist wie unter Figur 3 beschrieben.In principle, the same components as described in FIG. 3 are present in the second variant of a drive shown in FIG. 4 with a coupling via only one steering beam. The components are each denoted by three lines, i.e. bogie 1 '' ', wheelset bearing housing 2' '' to 7 '' 'with wheelsets 8' '' to 10 '' ', wheels 11' '', steering beam 12 '' 'with swivel axis 14 '' 'and joints 16' '', 24 '' ', 40' '', handlebars 17 '' 'to 20' '', joints 21 '' ', 25' '', handlebars 22 '' ', 34 '' ', 41' '', 42 '' ', angle lever 26' '', 27 '' 'with axes of rotation 28' '' and joints 29 '' 'as well as lever 35' '', 36 '' 'with joints 37 '' ', 39' '' and axis of rotation 38 '' '. However, while the steering beam 12 ″ of the variant according to FIG. 3 is located outside the wheel set 8 ″, the steering beam 12 ″ ″ in the variant according to FIG. 4 is arranged between the wheel sets 8 ″ ″ and 9 ″ ″. Accordingly, the handlebars 22 '' 'or 41' '' between the steering beam 12 '' 'and the angle lever 26' '' or between the steering beam 12 '' 'and the angle lever 27' '' are shorter than the corresponding handlebars 22 '', 41 ″ according to FIG. 3.
