Definitions
- the invention relates to a motor bogie for electric locomotives, in particular high-performance locomotives, with a bogie frame resiliently mounted on wheel axles, on which the vehicle frame is resiliently mounted, the traction motor and the gearbox flanged thereon being arranged inside the bogie frame and suspended at three points.
- Such a powered bogie is known for example from DE-PS 28 22 992, the motor-transmission unit being mounted on one point as a fulcrum in the locomotive body and in the vicinity of the wheelset on two pendulums. Finally, switchable coupling elements are provided between the unit and the bogie frame or the locomotive body. In this construction, the high-speed running should only be influenced by the fact that the drive bogie is coupled in a transverse direction when the locomotive is traveling straight.
- the effect generally known in the art as repayment is to be used to influence transverse and torsional vibrations about the vertical axis of the powered bogie and thereby decisively improve the stability of the vehicle.
- the traction motor and the gear unit flanged to it are pivotally mounted on the outside of the bogie frame and connected to the bogie frame inside by means of springs running perpendicularly and by means of a damper installed in the transverse direction to the longitudinal axis of the vehicle.
- This design has a very high moment of inertia around the vertical axis of the bogie, since the inherent moment of inertia of the motor-gear unit is fully effective.
- the object of the present invention was therefore to construct a motor bogie of the type specified in the introduction, in which the moment of inertia of the bogie is reduced as much as possible about its vertical axis, while at the same time improving the stability of the The Tilger effect comes into play when the vehicle runs, which is to be achieved in the simplest possible way using fewer and less complex components.
- the motor-gear unit is suspended on the bogie frame on the outer side of the wheelset with respect to the transverse center plane of the bogie frame on two perpendicular spring elements, preferably leaf springs.
- the spring elements in particular leaf springs, are relatively simple components which combine the carrier effect for the motor-transmission unit with a precisely defined elasticity, especially in the transverse direction.
- the absorber effect of the motor-transmission unit can be used for the torsional vibrations of the bogie about its vertical axis.
- a preferably hydraulic damper which acts in the transverse direction to the longitudinal axis of the vehicle is provided between the motor-gear unit and the bogie frame in a manner known per se.
- a variant that is structurally simple due to a small number of components, in which the moment of inertia of the bogie is reduced as far as possible about its vertical axis, can be achieved in that the unit on the motor side at a fixed pivot point on the inner side of the wheel set with respect to the transverse center plane of the bogie frame, preferably in the vicinity of the fulcrum of the bogie frame. This almost completely eliminates the unit's moment of inertia.
- the unit is suspended on the motor side on a pendulum on the bogie frame and is connected at least to the bogie frame via two links with intersecting axes.
- This makes it possible to arrange the fulcrum fixed to the bogie, but at any point which is given by the intersection of the lines of action of the two links.
- the rotation pole of the motor-transmission unit can be placed, for example, at the point most favorable for the vehicle running due to the stability conditions.
- An at least partial decoupling of the weight of the motor-gear unit from the bogie frame and at least partial cushioning of the mass of the unit via the secondary suspension results in a relatively simple construction in that the unit is mounted on the motor side at a pivot point in or on the vehicle frame.
- the moment of inertia of the bogie can also be reduced by reducing the influence of the moment of inertia of the unit in a variant with mounting of the unit on the vehicle frame if, according to a further feature of the invention, the unit on the motor side on a pendulum in Vehicle frame suspended and connected to the vehicle frame and / or the bogie frame via two links with intersecting axes.
- the fulcrum of the motor-gear unit can be fixed to the bogie or fixed to the vehicle frame.
- a handlebar can also be articulated on the vehicle frame, preferably parallel to the vertical vehicle center plane and oriented essentially horizontally.
- moments in defined directions can be decoupled from the bogie frame and absorbed by the vehicle frame, since the greatest accelerations of the motor-gearbox unit occur in the event of impact impacts (8 up to 5g).
- a longitudinal decoupling of the unit and the bogie frame is particularly advantageous, which is achieved by the parallel to the vertical vehicle center plane and substantially horizontal handlebar, which is provided between the motor-transmission unit and the vehicle frame, the special orientation of the handlebars gives the greatest possible load-bearing capacity even with the lowest possible weight of the arrangement.
- an improvement in the behavior in the case of torsional vibrations of the drive bogie can be achieved by arranging the two links parallel to one another in a manner known per se to the vertical vehicle center axis and to one another, these links preferably being essentially horizontal.
- the pivot point of the unit comes to infinity, so that only pure transversal shifts occur.
- the right part of a bogie frame 4 with the unit consisting of motor 1 and transmission 2 arranged in its interior.
- the unit 1, 2 is on two vertical leaf spring arrangements 5 on the outer side of the bogie frame 4 hung up.
- the unit 1, 2 is suspended from a fixed pivot point, which pivot point 21 is fixed to the bogie in the variant shown in FIG.
- a pivot point 31 can also be provided on the vehicle frame.
- FIG. 1c and 1d show suspensions of the motor-gear unit 1, 2 on pendulums, with additional links being provided between this unit 1, 2 and the bogie frame 4.
- the unit 1, 2 is suspended on the bogie frame 4 via the pendulum 41, and links 42 and 43 also connect the unit 1, 2 to the bogie frame 4.
- a pendulum 51 is used to suspend the unit 1, 2 provided on the vehicle frame, and links 52 and 53 are arranged according to Fig. 1c.
- a preferably electric traction motor 1 is connected to a flanged gear 2 and drives the wheel set 3 via conventional connecting elements.
- the wheel set 3 is mounted in a known manner via the primary suspension in the bogie frame 4, of which only the right half is closed see is.
- the motor-gear unit 1, 2 is suspended on the outside of the bogie frame 4 via two leaf spring arrangements 5 on the bogie frame 4. These leaf spring arrangements simultaneously fulfill the carrying function and also offer a precisely defined transverse elasticity for displacements or rotations of the unit 1, 2 transversely to the direction of travel of the rail vehicle.
- 2b shows the additionally provided, preferably hydraulic damper 6 for improved tuning and for more precise determination of the eradication effect of the motor-transmission unit 1, 2 for vibrations of the drive bogie about its vertical axis.
- the third suspension point of the unit 1, 2 is given in the variant according to FIGS. 2a and 2b by a fixed pivot point 21 on the central cross member 4 'of the bogie frame 4.
- this pivot point 21 which is arranged in the vicinity of the vertical axis of rotation of the bogie, allows a certain mobility of the unit 1, 2 about an axis passing through the pivot point 21 and oriented parallel to the vertical axis of rotation of the bogie frame 4.
- a likewise fixed pivot point 31 is provided, but which is provided on the vehicle frame and therefore decouples the majority of the weight of the unit 1, 2 from the bogie frame 4. Due to the engine-side suspension of the unit 1, 2 instead of on the central cross member 4 'of the bogie frame 4 via the pivot point 31 on the vehicle frame, the main part of the weight of the unit 1, 2 is suspended on the vehicle frame and is thus supported by the secondary suspension. For the mobility of the unit 1, 2 about the pivot point 31, what has been said in connection with the bogie fixed pivot point 21 applies.
- the engine-side suspension of the unit 1, 2 on the central cross member 4 'of the bogie frame 4 is realized via a pendulum 41.
- two links 42, 43 are provided which connect the unit 1, 2 in the illustrated case to the bogie frame 4, in particular to its central cross member 4 '.
- the handlebar 42 is preferably arranged parallel to the vertical vehicle center plane and oriented essentially horizontally in order to absorb the longitudinal forces emanating from the unit 1, 2 and to introduce them into the bogie frame 4 with the smallest possible structural size.
- the fulcrum of the unit 1, 2 is given by the intersection of the lines of action of the links 42, 43 and, with a suitable arrangement, can lie essentially anywhere at or outside the bogie. In the example shown, it is approximately at the location of the center of gravity of unit 1, 2.
- the handlebar 42 and / or the handlebar 43 can also be articulated on the vehicle frame instead of on the bogie frame 4.
- this is associated with the advantage that the longitudinal forces can no longer be introduced into the bogie frame 4 but into the vehicle frame and can be absorbed by the latter. This is particularly favorable because of the high accelerations that occur during impact impacts, which can amount to accelerations of up to 5 g.
- the pivot point of the unit 1, 2 instead of the variant fixed to the bogie shown in FIGS. 4a and 4b, can also be fixed, if desired, with respect to the vehicle frame by articulation of the two links 42, 43.
- the motor-gear unit 1, 2 is suspended via a pendulum 51, which, however, does not hang on the central cross member 4 ′ of the bogie frame, but is articulated in the vehicle frame.
- a pendulum 51 which, however, does not hang on the central cross member 4 ′ of the bogie frame, but is articulated in the vehicle frame.
- the pivot point of the unit 1, 2 is defined by two links 52, 53 with intersecting lines of action which, as shown, are arranged on the bogie frame 4 or its central cross member 4 '. As discussed previously, one or both of the links 52, 53 can also be connected to the vehicle frame.
- both handlebars are arranged both in FIGS. 4a and 4b and in FIGS. 5a and 5b both parallel to the vertical vehicle center plane and also parallel to one another, resulting in a pivot point at infinity and the unit 1, 2 performs only pure transverse movements compared to the bogie frame 4.

Abstract
Description
Die Erfindung betrifft ein Triebdrehgestell für elektrische Lokomotiven, insbesondere Hochleistungslokomotiven, mit einem auf Radachsen federnd gelagerten Drehgestellrahmen, auf dem federnd der Fahrzeugrahmen gelagert ist, wobei der Fahrmotor und das daran angeflanschte Getriebe im Inneren des Drehgestellrahmens angeordnet und an drei Punkten aufgehängt sind.The invention relates to a motor bogie for electric locomotives, in particular high-performance locomotives, with a bogie frame resiliently mounted on wheel axles, on which the vehicle frame is resiliently mounted, the traction motor and the gearbox flanged thereon being arranged inside the bogie frame and suspended at three points.
Ein derartiges Triebdrehgestell ist beispielsweise aus der DE-PS 28 22 992 bekannt, wobei die Motor-Getriebe-Einheit auf einem Punkt als Drehpunkt im Lokkasten und in der Radsatznähe auf zwei Pendel gelagert ist. Schließlich sind zwischen der Einheit und dem Drehgestellrahmen oder dem Lokkasten schaltbare Kupplungselemente vorgesehen. Bei dieser Konstruktion soll der Hochgeschwindigkeitslauf lediglich dadurch beeinflußt werden, daß das Triebdrehgestell bei gerader Fahrt mit dem Lokkasten in Querrichtung gekoppelt ist.Such a powered bogie is known for example from DE-PS 28 22 992, the motor-transmission unit being mounted on one point as a fulcrum in the locomotive body and in the vicinity of the wheelset on two pendulums. Finally, switchable coupling elements are provided between the unit and the bogie frame or the locomotive body. In this construction, the high-speed running should only be influenced by the fact that the drive bogie is coupled in a transverse direction when the locomotive is traveling straight.
Beim Triebdrehgestell gemäß der EP-OS 0 444 016 soll der in der Technik allgemein als Tilgung bekannte Effekt herangezogen werden, um Quer- und Drehschwingungen um die Hochachse des Triebdrehgestelles zu beeinflussen und dadurch die Stabilität des Fahrzeuges entscheidend zu verbessern. Zu diesem Zweck ist der Fahrmotor und das daran angeflanschte Getriebe an der Außenseite des Drehgestellrahmens schwenkbar gelagert und im Inneren über lotrecht verlaufende Federn und über einen in Querrichtung zur Längsachse des Fahrzeuges eingebauten Dämpfer mit dem Drehgestellrahmen verbunden. Diese Konstruktion weist ein sehr hohes Trägheitsmoment um die Hochachse des Drehgestelles auf, da das Eigenträgheitsmoment der MotorGetriebe-Einheit voll zum Tragen kommt.In the powered bogie according to EP-OS 0 444 016, the effect generally known in the art as repayment is to be used to influence transverse and torsional vibrations about the vertical axis of the powered bogie and thereby decisively improve the stability of the vehicle. For this purpose, the traction motor and the gear unit flanged to it are pivotally mounted on the outside of the bogie frame and connected to the bogie frame inside by means of springs running perpendicularly and by means of a damper installed in the transverse direction to the longitudinal axis of the vehicle. This design has a very high moment of inertia around the vertical axis of the bogie, since the inherent moment of inertia of the motor-gear unit is fully effective.
Die Aufgabe der vorliegenden Erfindung lag daher darin, ein Triebdrehgestell der eingangs angegebenen Art zu konstruieren, bei welchem das Trägheitsmoment des Drehgestells um seine Hochachse so weit als möglich verringert ist, wobei gleichzeitig zur Verbesserung der Stabilität des Fahrzeuglaufes der Tilger-Effekt zum Tragen kommt, welcher auf die konstruktiv einfachst mögliche Weise unter Verwendung weniger und wenig aufwendiger Bauteile erzielt werden soll.The object of the present invention was therefore to construct a motor bogie of the type specified in the introduction, in which the moment of inertia of the bogie is reduced as much as possible about its vertical axis, while at the same time improving the stability of the The Tilger effect comes into play when the vehicle runs, which is to be achieved in the simplest possible way using fewer and less complex components.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Motor-Getriebe-Einheit auf der äußeren Seite des Radsatzes bezüglich der Quermittelebene des Drehgestellrahmens auf zwei lotrecht verlaufenden Federelementen, vorzugsweise Blattfedern, am Drehgestellrahmen aufgehängt ist. Die Federelemente, insbesondere Blattfedern, sind relativ einfache Bauteile, welche die Trägerwirkung für die Motor-Getriebe-Einheit mit einer genau definierten Elastizität, speziell in Querrichtung, kombinieren. Bei konstruktiv einfacher Bauweise ist dabei die Tilgerwirkung der Motor-Getriebe-Einheit für die Drehschwingungen des Drehgestells um seine Hochachse ausnutzbar. Wenn die Einheit auf der äußeren Seite des Radsatzes auf den Federelementen hängt und damit der Drehpunkt zwischen der Radsatzachse und der Drehgestellmitte liegt, kommt ein zusätzlicher Vorteil hinzu, der darin besteht, daß das Trägheitsmoment des Drehgestells um seine Hochachse vermindert ist, weil der Beitrag des Eigenträgheitsmoments der Motor-Getriebe-Einheit geringer ist.This object is achieved in that the motor-gear unit is suspended on the bogie frame on the outer side of the wheelset with respect to the transverse center plane of the bogie frame on two perpendicular spring elements, preferably leaf springs. The spring elements, in particular leaf springs, are relatively simple components which combine the carrier effect for the motor-transmission unit with a precisely defined elasticity, especially in the transverse direction. With a structurally simple construction, the absorber effect of the motor-transmission unit can be used for the torsional vibrations of the bogie about its vertical axis. If the unit on the outer side of the wheelset hangs on the spring elements and thus the pivot point lies between the wheelset axis and the center of the bogie, there is an additional advantage, which is that the moment of inertia of the bogie is reduced about its vertical axis because the contribution of the The moment of inertia of the motor-gear unit is lower.
Vorzugsweise ist gemäß einem weiteren Merkmal der Erfindung zwischen der Motor-Getriebe-Einheit und dem Drehgestellrahmen in an sich bekannter Weise ein in Querrichtung zur Längsachse des Fahrzeuges wirkender, vorzugsweise hydraulischer, Dämpfer vorgesehen. Damit ist durch die verbesserte Abstimmbarkeit der Schwingungscharakteristik der Einheit gegenüber dem Drehgestellrahmen eine weitere Verbesserung der Tilgewirkung unter Beibehaltung der zuvor angeführtn Vorteile möglich.According to a further feature of the invention, a preferably hydraulic damper which acts in the transverse direction to the longitudinal axis of the vehicle is provided between the motor-gear unit and the bogie frame in a manner known per se. The improved tunability of the vibration characteristics of the unit compared to the bogie frame makes it possible to further improve the tilting effect while maintaining the advantages mentioned above.
Eine durch eine geringe Anzahl an Bauteilen konstruktiv einfache Variante, bei der das Trägheitsmoment des Drehgestells um seine Hochachse im weitestmöglichen Rahmen vermindert ist, kann dadurch erzielt werden, daß die Einheit motorseitig an einem festen Drehpunkt auf der inneren Seite des Radsatzes bezüglich der Quermittelebene des Drehgestellrahmens, vorzugsweise in der Nähe vom Drehpunkt des Drehgestellrahmens, gelagert ist. Dadurch fällt das Eigenträgheitsmoment der Einheit fast ganz weg.A variant that is structurally simple due to a small number of components, in which the moment of inertia of the bogie is reduced as far as possible about its vertical axis, can be achieved in that the unit on the motor side at a fixed pivot point on the inner side of the wheel set with respect to the transverse center plane of the bogie frame, preferably in the vicinity of the fulcrum of the bogie frame. This almost completely eliminates the unit's moment of inertia.
Anderseits kann vorgesehen sein, daß die Einheit motorseitig an einem Pendel am Drehgestellrahmen aufgehängt und über zwei Lenker mit einander schneidenden Achsen zumindest mit dem Drehgestellrahmen verbunden ist. Damit besteht die Möglichkeit, den Drehpunkt drehgestellfest, jedoch an einer beliebigen Stelle, die durch den Schnittpunkt der Wirklinien der beiden Lenker gegeben ist, anzuordnen. Damit kann der Drehpol der Motor-Getriebe-Einheit beispielsweise an die durch die Stabilitätsbedingungen für den Fahrzeuglauf günstigste Stelle gelegt werden.On the other hand, it can be provided that the unit is suspended on the motor side on a pendulum on the bogie frame and is connected at least to the bogie frame via two links with intersecting axes. This makes it possible to arrange the fulcrum fixed to the bogie, but at any point which is given by the intersection of the lines of action of the two links. In this way, the rotation pole of the motor-transmission unit can be placed, for example, at the point most favorable for the vehicle running due to the stability conditions.
Eine zumindest teilweise Entkoppelung des Gewichts der MotorGetriebe-Einheit vom Drehgestellrahmen und zumindest teilweise Abfederung der Masse der Einheit über die Sekundärfederung ergibt sich bei relativ einfacher Bauweise dadurch, daß die Einheit motorseitig an einem Drehpunkt im oder am Fahrzeugrahmen gelagert ist.An at least partial decoupling of the weight of the motor-gear unit from the bogie frame and at least partial cushioning of the mass of the unit via the secondary suspension results in a relatively simple construction in that the unit is mounted on the motor side at a pivot point in or on the vehicle frame.
Unter Beibehaltung des soeben genannten Vorhaltes der zumindest teilweisen Gewichtsentkoppelung kann auch bei einer Variante mit Lagerung der Einheit am Fahrzeugrahmen das Trägheitsmoment des Drehgestells durch Verringern des Einflusses des Eigenträgheitsmoments der Einheit vermindert werden, wenn gemäß einem weiteren Merkmal der Erfindung die Einheit motorseitig an einem Pendel im Fahrzeugrahmen aufgehängt und über zwei Lenker mit einander schneidenden Achsen mit dem Fahrzeugrahmen und/oder dem Drehgestellrahmen verbunden ist. Je nach den gewünschten Bedingungen kann dabei der Drehpunkt der Motor-Getriebe-Einheit drehgestellfest oder gegenüber dem Fahrzeugrahmen fest vorgesehen sein.While maintaining the just-mentioned provision of the at least partial decoupling of weight, the moment of inertia of the bogie can also be reduced by reducing the influence of the moment of inertia of the unit in a variant with mounting of the unit on the vehicle frame if, according to a further feature of the invention, the unit on the motor side on a pendulum in Vehicle frame suspended and connected to the vehicle frame and / or the bogie frame via two links with intersecting axes. Depending on the desired conditions, the fulcrum of the motor-gear unit can be fixed to the bogie or fixed to the vehicle frame.
Sowohl bei einer Aufhängung der Einheit am Drehgestell als auch am Fahrzeugrahmen kann ein Lenker am Fahrzeugrahmen angelenkt, vorzugsweise parallel zur senkrechten Fahrzeugmittelebene und im wesentlichen horizontal orientiert sein. Durch diese Art von Konstruktion können Momente in definierten Richtungen vom Drehgestellrahmen entkoppelt und vom Fahrzeugrahmen aufgenommen werden, da die größten Beschleunigungen der Motor-Getriebe-Einheit bei Auflaufstößen auftreten (8bis zu 5g) ist eine Längsentkoppelung der Einheit und des Drehgestellrahmens von besonderem Vorteil, was durch den parallel zur senkrechten Fahrzeugmittelebene und im wesentlichen horizontalen Lenker, der zwischen Motor-Getriebe-Einheit und Fahrzeugrahmen vorgesehen ist, erreicht wird, wobei die spezielle Orientierung des Lenkers die größtmögliche Belastbarkeit auch der Lagerstellen bei geringstmöglichem Gewicht der Anordnung ergibt.Both when the unit is suspended on the bogie A handlebar can also be articulated on the vehicle frame, preferably parallel to the vertical vehicle center plane and oriented essentially horizontally. With this type of construction, moments in defined directions can be decoupled from the bogie frame and absorbed by the vehicle frame, since the greatest accelerations of the motor-gearbox unit occur in the event of impact impacts (8 up to 5g). A longitudinal decoupling of the unit and the bogie frame is particularly advantageous, which is achieved by the parallel to the vertical vehicle center plane and substantially horizontal handlebar, which is provided between the motor-transmission unit and the vehicle frame, the special orientation of the handlebars gives the greatest possible load-bearing capacity even with the lowest possible weight of the arrangement.
Durch eine Anlenkung beider Lenker am Fahrzeugrahmen kann eine totale Entkoppelung der Momente der Motor-Getriebe-Einheit vom Drehgestellrahmen und ein fahrzeugrahmenfester Drehpunkt der Einheit erreicht werden.By articulating both control arms on the vehicle frame, a total decoupling of the moments of the motor-transmission unit from the bogie frame and a pivot point of the unit fixed to the vehicle frame can be achieved.
Eine Verbesserung des Verhaltens bei Drehschwingungen des Triebdrehgestells kann gemäß einem weiteren Merkmal der Erfindung durch eine parallele Anordnung beider Lenker in an sich bekannter Weise zur senkrechten Fahrzeugmittelachse und zueinander erreicht werden, wobei diese Lenker vorzugsweise im wesentlichen horizontal liegen. Damit kommt der Drehpunkt der Einheit ins Unendliche zu liegen, sodaß nur reine Transversalverschiebungen eintreten.According to a further feature of the invention, an improvement in the behavior in the case of torsional vibrations of the drive bogie can be achieved by arranging the two links parallel to one another in a manner known per se to the vertical vehicle center axis and to one another, these links preferably being essentially horizontal. Thus the pivot point of the unit comes to infinity, so that only pure transversal shifts occur.

Beispielsweise ist in Fig. 1c die Einheit 1,2 über das Pendel 41 am Drehgestellrahmen 4 aufgehängt und Lenker 42 und 43 verbinden die Einheit 1,2 ebenfalls mit dem Drehgestellrahmen 4. Gemäß Fig. 1d ist ein Pendel 51 zur Aufhängung der Einheit 1,2 am Fahrzeugrahmen vorgesehen, und Lenker 52 und 53 sind entsprechend der Fig. 1c angeordnet.1c and 1d show suspensions of the motor-
Nachfolgend sollen die dargestellten Varianten näher erläutert werden. Die allen Varianten gemeinsamen Bauteile werden nur einmal anhand der Fig. 2a und 2b erläutert und sind in allen Fig. mit denselben Bezugszeichen gekennzeichnet.The variants shown will be explained in more detail below. The components common to all variants are only explained once with reference to FIGS. 2a and 2b and are identified in all figures with the same reference numerals.
Ein vorzugsweise elektrischer Fahrmotor 1 ist mit einem angeflanschten Getriebe 2 verbunden und treibt über konventionelle Verbindungselemente den Radsatz 3 an. Der Radsatz 3 ist in bekannter Weise über die Primärfederung im Drehgestellrahmen 4 gelagert, von dem nur die rechte Hälfte zu sehen ist. Die Motor-Getriebe-Einheit 1,2 ist an der äußeren Seite des Drehgestellrahmens 4 über zwei Blattfederanordnungen 5 am Drehgestellrahmen 4 aufgehängt. Diese Blattfederanordnungen erfüllen gleichzeitig die Tragefunktion und bieten auch eine genau definierte Querelastizität für Verschiebungen oder Verdrehungen der Einheit 1,2 quer zur Fahrtrichtung des Schienenfahrzeuges. In Fig. 2b ist der zusätzlich vorgesehene, vorzugsweise hydraulische Dämpfer 6 zur verbesserten Abstimmung und zur genaueren Bestimmung der Tilgungswirkung der Motor-Getriebe-Einheit 1,2 für Schwingungen des Triebdrehgestelles um seine Hochachse gezeigt.A preferably
Der dritte Aufhängungspunkt der Einheit 1,2 ist bei der Variante gemäß den Fig. 2a und 2b durch einen fixen Drehpunkt 21 am mittleren Querträger 4' des Drehgestellrahmens 4 gegeben. Insbesondere erlaubt dieser Drehpunkt 21, der in der Nähe der vertikalen Drehachse des Drehgestelles angeordnet ist, eine gewisse Beweglichkeit der Einheit 1,2 um eine durch den Drehpunkt 21 gehende und parallel zur vertikalen Drehachse des Drehgestellrahmens 4 orientierte Achse.The third suspension point of the
In Fig. 3a und 3b ist ein ebenfalls fester Drehpunkt 31 vorgesehen, der aber am Fahrzeugrahmen vorgesehen ist und daher den Großteil des Gewichts der Einheit 1,2 vom Drehgestellrahmen 4 entkoppelt. Durch die motorseitige Aufhängung der Einheit 1,2 anstelle am mittleren Querträger 4' des Drehgestellrahmens 4 über den Drehpunkt 31 am Fahrzeugrahmen ist der Hauptteil des Gewichts der Einheit 1,2 am Fahrzeugrahmen aufgehängt und damit über die Sekundärfederung abgestützt. Für die Beweglichkeit der Einheit 1,2 um den Drehpunkt 31 gilt das in Verbindung mit dem drehgestellfesten Drehpunkt 21 Gesagte.3a and 3b, a likewise fixed
In Fig. 4a und 4b ist die motorseitige Aufhängung der Einheit 1,2 am mittleren Querträger 4' des Drehgestellrahmens 4 über ein Pendel 41 realisiert. Um nun den Drehpunkt der Einheit 1,2 festzulegen, sind zwei Lenker 42,43 vorgesehen, welche die Einheit 1,2 im dargestellten Fall mit dem Drehgestellrahmen 4, insbesondere mit dessen mittlerem Querträger 4' verbinden. Dabei ist der Lenker 42 vorzugsweise parallel zur senkrechten Fahrzeugmittelebene und im wesentlichen horizontal orientiert angeordnet, um bei geringstmöglicher Baugröße die von der Einheit 1,2 ausgehenden Längskräfte aufzunehmen und in den Drehgestellrahmen 4 einzuleiten. Der Drehpunkt der Einheit 1,2 ist durch den Schnittpunkt der Wirklinien der Lenker 42,43 gegeben und kann bei geeigneter Anordnung im wesentlichen an einer beliebigen Stelle innerhalb oder außerhalb des Drehgestelles liegen. Im gezeigten Beispiel ist er etwa an der Stelle des Schwerpunktes der Einheit 1,2.4a and 4b, the engine-side suspension of the
Selbstverständlich kann der Lenker 42 und/oder der Lenker 43 anstelle am Drehgestellrahmen 4 auch am Fahrzeugrahmen angelenkt sein. Für den Lenker 42 ist dies mit dem Vorteil verbunden, daß die Längskräfte nicht mehr in den Drehgestellrahmen 4 sondern in den Fahrzeugrahmen eingeleitet und von diesem aufgenommen werden können. Dies ist wegen der hohen auftretenden Beschleunigungen bei Auflaufstößen, welche Beschleunigungen bis zu 5g betragen können, besonders günstig. Auch kann der Drehpunkt der Einheit 1,2 anstelle der in den Fig. 4a und 4b gezeigten drehgestellfesten Variante durch Anlenkung der beiden Lenker 42,43, wenn gewünscht, auch gegenüber dem Fahrzeugrahmen festgelegt werden.Of course, the
Analog der Fig.4a und 4b ist bei der Variante in Fig. 5a und 5b die Motor-Getriebe-Einheit 1,2 über ein Pendel 51 aufgehängt, welches aber nicht am mittleren Querträger 4' des Drehgestellrahmens hängt, sondern im Fahrzeugrahmen angelenkt ist. Dadurch kommt es zu einer teilweisen Gewichtsentkoppelung zwischen der Masse der Einheit 1,2 und dem Drehgestellrahmen 4 und durch die motorseitige Anordnung des Pendels 51 kann ein Großteil der Masse der Einheit 1,2 über die Sekundärfederung abgestützt werden.Analogous to FIGS. 4 a and 4 b, in the variant in FIGS. 5 a and 5 b, the motor-
Auch bei dieser in den Fig. 5a und 5b gezeigten Variante wird der Drehpunkt der Einheit 1,2 über zwei Lenker 52,53 mit einander schneidenden Wirklinien definiert, welche, wie dargestellt, am Drehgestellrahmen 4 bzw. dessen mittleren Querträger 4' angeordnet sind. Wie zuvor diskutiert, kann einer oder können beide Lenker 52,53 aber auch mit dem Fahrzeugrahmen verbunden sein.5a and 5b, the pivot point of the
Nicht dargestellt ist eine Variante, bei der beide Lenker sowohl in der Fig. 4a und 4b als auch der Fig. 5a und 5b sowohl parallel zur senkrechten Fahrzeugmittelebene und auch parallel zueinander angeordnet sind, wobei sich ein Drehpunkt im Unendlichen ergibt und die Einheit 1,2 gegenüber dem Drehgestellrahmen 4 nur reine Transversalbewegungen ausführt.Not shown is a variant in which both handlebars are arranged both in FIGS. 4a and 4b and in FIGS. 5a and 5b both parallel to the vertical vehicle center plane and also parallel to one another, resulting in a pivot point at infinity and the
