Definitions
- the invention relates to a working device for a soil treatment device with a milling drum with a Fräswalzenrohr, on the surface of working tools are mounted projecting, which are intended during the milling process in contact with the milled material, wherein the working device comprises a drive train for driving the milling drum.
- Tillage machines are known in many designs.
- the DE 201 22 928 U1 as a tillage machine, a road milling machine. It has a drive train. This includes a drive motor, a clutch and a transmission (the so-called "Fräswalzengetriebe"), and these units mediating organs, in particular shafts, gear or endless drives.
- a drive train is to be understood in particular under the above definition.
- Work tools are understood to mean the assemblies of the milling drum, which functionally interact with the milled material during the working process. For example, these are cutting tools and the tool holders carrying the milling tools. Furthermore, often work tools and ejector tools are mounted on the milling drum as working tools. These have guiding and promotion functions.
- the work result is significantly influenced by the speed of the milling drum.
- the optimum speed is generally dependent on the application.
- a high weight of the tillage machine helps to increase the smoothness even at low speeds.
- this is disadvantageous in several respects, as this must be made on the one hand special demands on the transport (large milling> 40t ⁇ heavy transport) and on the other hand, the application is limited to static unsustainable surfaces.
- At least one load weight is preferably arranged interchangeably on the drive train and / or on the milling drum to increase the kinetic energy.
- the invention is based on the recognition that a higher smoothness of the milling drums can be achieved when the kinetic energy in the drive train and / or the milling drum is increased.
- m is the amount of rotating mass and r is the distance of this mass from the axis of rotation.
- the product mr 2 represents the moment of inertia of the moving Mass and ⁇ the angular velocity (2 * ⁇ * speed). Since the reduction of the speed is desired, the invention now starts on the change of the moment of inertia.
- one or more load weights are installed on one or more rotating parts of the drive train or the milling drum.
- a reduction in the speed also brings the advantage of a longer running time of the machine before it has to be refueled with coolant. Furthermore, due to the lower speed reduces the dust, resulting in a further reduction in water consumption.
- the ballast weight may be located anywhere on the drive train or on the milling drum. Accordingly, it may be positioned, for example, after the drive motor.
- the drive train has a clutch and this downstream, for example via a belt drive, a transmission, and that the load weight downstream to the output side or in the transmission is arranged.
- This arrangement leads to a relief of the clutch and the transmission, since then the shock factor acting on it is reduced. If the or the load weights are arranged after the transmission, this unit can be effectively relieved. This increases the service life of the clutch and transmission.
- the load weight may be fixedly connected to the drive train or the milling drum. Preferably, however, it is interchangeable. In this way it can then be grown on the soil tillage machine when it is needed specifically for the purpose of the desired smoothness.
- a weight-optimized adaptation of the machine can also be made here. It also simplifies the machine transport, since the or the load weights separately handled, for example, can be transported. In addition, the roll change is simplified because a lighter roller is easier to change and handle.
- At least one load weight is arranged in the region of the milling drum.
- the ballast weight can be used particularly effectively, since it can be arranged at a great distance from the axis of rotation. This leads to a particular increase in smoothness, since the moment of inertia, and thus the kinetic energy depend quadratically on the distance of the mass to the axis of rotation.
- the arrangement in the area of the milling drum also brings handling advantages.
- the ballast weights are easily accessible here if they are interchangeable arranged.
- a significant increase in smoothness results when it is provided that the load or weights have a mass which is suitable for increasing the moment of inertia of the milling drum by at least 10%, particularly preferably by at least 20%. With an increase of at least 20%, there is also the advantage that a significant reduction in the weight of the machine is possible.
- An experimental set-up by the inventor showed that an increase of 100 kg in the milling drum enables a reduction of the total machine weight by 100 kg with a constant smoothness.
- a conceivable variant of the invention is such that the drive train and / or the milling drum are prepared in such a way that with the load weights the weight can be increased in two or more stages. In this way, the soil tillage machine can be gradually adjusted to the desired work task.
- this subdivision of the load weights is accompanied by a particularly simple handling.
- a tillage machine may be such that receptacles are arranged on the drive train and / or the milling drum by means of which the load or weights can be interchangeably coupled. In this way, the load weights can be safely and reliably positioned and secured in rough construction site operation.
- the ballast weights can be formed here, for example, by segments or rings or similar units.
- the load or weights are mounted in the space enclosed by the milling drum tube interior, preferably on the inside of the Fräswalzenrohrs. Then the load weights are protected from the attack of the milled material in a simple way.
- a possible inventive design may be such that the ballast weight is formed by a fluid held in a fluid reservoir.
- a fluid for example, water can be used as the fluid. This can easily be drained after use.
- the milling drum can be detachably mounted on coupling pieces of the drive train by means of a fastening arrangement, and that the load weights are interchangeably arranged on the fastening arrangement.
- the load weights are easily accessible, especially when the milling drum is disassembled.
- a conceivable embodiment of the invention is such that a hardened casting compound, preferably concrete, is used as a load-on weight. With this measure, the charge can be made inexpensively and easily effective.
- the charge according to the invention is not possible alone with mechanical drives with an internal combustion engine. Rather, an increase in other drive variants of the milling drum is possible. For example, it is conceivable to load hydraulic or electric milling drum drives on their rotating components and / or the milling drum, wherein the same advantages can be achieved.

Description
Die Erfindung betrifft ein Arbeitseinrichtung für eine Bodenbearbeitungseinrichtung mit einer Fräswalze mit einem Fräswalzenrohr, auf dessen Oberfläche Arbeitswerkzeuge abstehend aufgebracht sind, die dazu vorgesehen sind während des Fräsprozesses in Kontakt mit dem Fräsgut zu treten, wobei die Arbeitseinrichtung einen Antriebsstrang zum Antrieb der Fräswalze umfasst.The invention relates to a working device for a soil treatment device with a milling drum with a Fräswalzenrohr, on the surface of working tools are mounted projecting, which are intended during the milling process in contact with the milled material, wherein the working device comprises a drive train for driving the milling drum.
Bodenbearbeitungsmaschinen sind in vielfältigen Ausführungen bekannt. Beispielsweise offenbart die
Bei der Verwendung einer erfindungsgemäßen Maschine wird das Arbeitsergebnis maßgeblich von der Drehzahl der Fräswalze beeinflusst. Hierbei ist die optimale Drehzahl im Allgemeinen von der Anwendung abhängig.When using a machine according to the invention the work result is significantly influenced by the speed of the milling drum. Here, the optimum speed is generally dependent on the application.
Beim Feinfräsen von Straßenoberflächen, zur Wiederherstellung der Griffigkeit, mit geringer Frästiefe, werden im Verhältnis höhere Drehzahlen benötigt, um ein einheitliches Fräsbild zu erzeugen. Mithin erfolgt hier lediglich eine oberflächliche Bearbeitung.When fine milling road surfaces, to restore the grip, with low cutting depth, relatively high speeds are required in order to produce a uniform Fräsbild. Consequently, only a superficial processing takes place here.
Beim Ausbau von ganzen oder mehreren Schichten des Straßenaufbaus sind tendenziell niedrigere Drehzahlen günstiger, da sich gezeigt hat, dass hierdurch ein besseres Fräsbild unter einer geringeren Entwicklung von Feinkornanteilen und daher reduzierte Staubentwicklung gewährleistet werden kann. Darüber hinaus wird der Verschleiß an den Fräswerkzeugen bei niedrigen Drehzahlen deutlich reduziert. Weiterhin wird bei reduzierter Fräswalzendrehzahl auch eine reduzierte Ausgangsleistung des Antriebes benötigt und somit ein niedrigerer Kraftstoffverbrauch ermöglicht. Insgesamt ist bei solchen Anwendungen daher eine möglichst geringe Fräswalzendrehzahl anzustreben.When removing whole or multiple layers of road construction, lower rotational speeds tend to be more favorable since it has been shown that a better milling pattern can be ensured with a lower development of fine grain fractions and therefore reduced dust development. In addition, the wear on the milling tools at low speeds is significantly reduced. Furthermore, with reduced milling drum speed, a reduced output power of the drive is required and thus enables a lower fuel consumption. Overall, therefore, the lowest possible Fräswalzendrehzahl is desirable in such applications.
Um den verschiedenen Anforderungen gerecht zu werden ist es daher bekannt die Fräswalzendrehzahl bei Straßenfräsen variabel einstellen zu können.In order to meet the various requirements, it is therefore known to be able to variably set the milling drum speed for road milling machines.
Wird die Drehzahl jedoch zu niedrig gewählt reicht die kinetische Energie der Fräswalze nicht mehr aus um das Fräsgut effektiv zu bearbeiten, es kommt zu einem unrunden und unruhigen Lauf der Fräswalze der sich unter anderem durch Vibrationen der gesamten Bodenbearbeitungsmaschine bis hin zum Aufschaukeln der Maschine zeigt, hierbei können auch Beschädigungen an der Maschine auftreten. Weiterhin leidet durch den unruhigen Lauf der Fräswalze die Arbeitsqualität und es können Ungleichmäßigkeiten im Fräsbild auftreten. Im Extremfall kann bei nicht ausreichender kinetischer Energie die Fräswalze "steckenbleiben".However, if the speed is chosen too low, the kinetic energy of the milling drum is no longer sufficient to effectively process the milled material, there is a non-circular and uneven running of the milling drum, which manifests itself, inter alia, as vibrations of the entire soil tillage machine up to the rocking of the machine, Damage to the machine can also occur here. Furthermore suffers due to the troubled running of the milling drum, the quality of work and it may occur irregularities in the milling pattern. In extreme cases, if not enough kinetic energy, the milling drum "stuck".
Ein hohes Gewicht der Bodenbearbeitungsmaschine trägt dazu bei die Laufruhe auch bei niedrigen Drehzahlen zu erhöhen. Dies ist allerdings in mehrfacher Hinsicht nachteilig, da hierdurch zum einen besondere Anforderungen an den Transport gestellt werden müssen (Großfräsen > 40t → Schwertransport) und zum anderen die Einsatzmöglichkeiten auf statisch wenig tragfähigen Untergründen eingeschränkt wird.A high weight of the tillage machine helps to increase the smoothness even at low speeds. However, this is disadvantageous in several respects, as this must be made on the one hand special demands on the transport (large milling> 40t → heavy transport) and on the other hand, the application is limited to static unsustainable surfaces.
Es ist daher bekannt Fräsmaschinen zur Stabilisierung aufzulasten. Hierzu werden auf der Maschine Zusatzgewichte befestigt. So ist es beispielsweise bekannt, bei einer Straßenfräsmaschine mit ca. 4,5 Tonnen Gesamtgewicht 1,3 Tonnen durch Zusatzgewichte verfügbar zu machen. Mit anderen Worten machen die Zusatzgewichte knapp 1/3 des Maschinengewichtes aus. Eine solche Maschine ist somit flexibel einsetzbar, muss jedoch für die optimale Anpassung an die jeweilige Aufgabenstellung mit großen Zusatzgewichten aufgelastet werden.It is therefore known to load milling machines for stabilization. For this purpose, additional weights are attached to the machine. It is known, for example, to make 1.3 tons available through additional weights in a road milling machine with a total weight of approximately 4.5 tons. In other words, the additional weights account for almost 1/3 of the weight of the machine. Such a machine is thus flexible in use, but must be charged for optimal adaptation to the task at hand with large additional weights.
Aus der
Eine flexible Anpassung an die jeweilige Aufgabenstellung kann bei dieser Ausgestaltung des Fräswalzenrohres darüber hinaus nicht erfolgen.A flexible adaptation to the respective task can not take place in this embodiment of the Fräswalzenrohres beyond.
Es ist also Aufgabe der Erfindung, eine Arbeitseinrichtung der eingangs erwähnten Art bereitzustellen, die eine Optimierung der Fräswalzendrehzahl ermöglicht, wobei bei unterschiedlichen Anwendungen auf einfache Weise ein optimales Schnittbild erzeugt werden kann.It is therefore an object of the invention to provide a working device of the type mentioned, which allows an optimization of Fräswalzendrehzahl, wherein in different applications in an easy way, an optimal cross-sectional image can be generated.
Diese Aufgabe wird dadurch gelöst, dass am Antriebsstrang und/oder an der Fräswalze zur Steigerung der kinetischen Energie wenigstens ein Auflastgewicht vorzugsweise auswechselbar angeordnet ist.This object is achieved in that at least one load weight is preferably arranged interchangeably on the drive train and / or on the milling drum to increase the kinetic energy.
Die Erfindung baut auf der Erkenntnis auf, dass eine höhere Laufruhe der Fräswalzen dann erreicht werden kann, wenn die kinetische Energie im Antriebsstrang und/oder der Fräswalze erhöht wird. Die kinetische Energie ergibt sich nach der Formel
Wobei m den Betrag der rotierende Masse und r den Abstand dieser Masse von der Rotationsachse angibt. Das Produkt mr2 stellt das das Trägheitsmoment der bewegten Masse und ω die Winkelgeschwindigkeit (2 * π * Drehzahl) dar. Da die Reduzierung der Drehzahl erwünscht ist setzt die Erfindung nun an der Änderung des Trägheitsmoments an. Dabei werden ein oder mehrere Auflastgewichte an einem oder mehreren rotierenden Teilen des Antriebsstranges oder der Fräswalze verbaut.Where m is the amount of rotating mass and r is the distance of this mass from the axis of rotation. The product mr 2 represents the moment of inertia of the moving Mass and ω the angular velocity (2 * π * speed). Since the reduction of the speed is desired, the invention now starts on the change of the moment of inertia. In this case, one or more load weights are installed on one or more rotating parts of the drive train or the milling drum.
Versuche haben ergeben, dass unter sonst gleichen Bedingungen durch die Reduzierung der Drehzahl bei gleichzeitiger Erhöhung des Trägheitsmomentes die Leistungsaufnahme während des Fräsprozesses um bis zu 30% gesenkt werden kann. Damit reduzieren sich neben dem Kraftstoffbedarf auch der Meißelverschleiß und der Kühlmittelbedarf. Auf diese Weise kann die Masse des mitgeführten Kühlmittels (Wasser) zu Gunsten eines geringeren Maschinengewichts verringert werden.Experiments have shown that under otherwise identical conditions by reducing the speed while increasing the moment of inertia, the power consumption during the milling process can be reduced by up to 30%. This not only reduces fuel consumption but also chisel wear and coolant requirements. In this way, the mass of the entrained coolant (water) can be reduced in favor of a lower machine weight.
Eine Verringerung der Drehzahl bringt darüber hinaus auch den Vorteil einer längeren Laufzeit der Maschine, bevor diese mit Kühlmittel betankt werden muss. Weiterhin verringert sich aufgrund der niedrigeren Drehzahl die Staubentwicklung, was zu einer weiteren Absenkung des Wasserbedarfes führt.A reduction in the speed also brings the advantage of a longer running time of the machine before it has to be refueled with coolant. Furthermore, due to the lower speed reduces the dust, resulting in a further reduction in water consumption.
Weiterhin hat sich gezeigt, dass mit einer Erhöhung des Trägheitsmomentes durch die Auflastung an der Fräswalze und/oder im Antriebsstrang die gleiche Steigerung der Laufruhe erreicht werden kann wie durch eine deutlich höhere Auflastung der Gesamtmaschine. Unter sonst gleichen Umständen können hier ganzzahlige Faktoren dazwischen liegen.Furthermore, it has been shown that with an increase in the moment of inertia by the load on the milling drum and / or in the drive train, the same increase in smoothness can be achieved as by a much higher load on the overall machine. Under otherwise identical circumstances integer factors may lie between them.
Daher besteht durch die Erhöhung des Trägheitsmomentes ebenfalls die Möglichkeit bei gleichbleibender Laufruhe das Gesamtgewicht der Maschine zu reduzieren. Damit ist es möglich die Maschine flexibler einzusetzen und der Transport wird vereinfacht.Therefore, by increasing the moment of inertia, it is also possible to reduce the overall weight of the machine while keeping the running smoothness constant. This makes it possible to use the machine more flexibly and the transport is simplified.
Insgesamt wird somit eine anwendungsgerechte Abstimmung zwischen Walzendrehzahl und Maschinengewicht ermöglicht indem eine entsprechende Auflastung der Fräswalze und/oder des Antriebsstranges für den jeweiligen Anwendungsfall gewählt wird.Overall, an application-appropriate coordination between roller speed and machine weight is thus made possible by a corresponding load of the milling drum and / or the drive train is selected for the particular application.
Dies ist insbesondere bei auswechselbaren Gewichten vorteilhaft, da hiermit eine Maschine und/oder Fräswalze für unterschiedliche Aufgabenstellungen verwendet und einfach für diese jeweils optimal angepasst werden kann.This is particularly advantageous in interchangeable weights, since hereby a machine and / or milling drum used for different tasks and can be easily optimally adapted for each.
Das Auflastgewicht kann an einer beliebigen Stelle des Antriebsstranges oder an der Fräswalze angeordnet sein. Dementsprechend kann es beispielsweise nach dem Antriebsmotor positioniert sein.The ballast weight may be located anywhere on the drive train or on the milling drum. Accordingly, it may be positioned, for example, after the drive motor.
Gemäß einer bevorzugten Ausgestaltungsvariante der Erfindung kann es vorgesehen sein, dass der Antriebsstrang eine Kupplung und dieser beispielsweise über einen Riementrieb nachgeschaltet ein Getriebe aufweist, und dass das Auflastgewicht stromabwärts nach oder ausgangsseitig im Getriebe angeordnet ist.According to a preferred embodiment variant of the invention, it can be provided that the drive train has a clutch and this downstream, for example via a belt drive, a transmission, and that the load weight downstream to the output side or in the transmission is arranged.
Diese Anordnung führt zu einer Entlastung der Kupplung und des Getriebes, da dann der auf sie einwirkende Stoßfaktor reduziert wird. Wenn das oder die Auflastgewichte nach dem Getriebe angeordnet sind, kann auch diese Baueinheit wirkungsvoll entlastet werden. Hierdurch wird die Lebensdauer von Kupplung und Getriebe gesteigert.This arrangement leads to a relief of the clutch and the transmission, since then the shock factor acting on it is reduced. If the or the load weights are arranged after the transmission, this unit can be effectively relieved. This increases the service life of the clutch and transmission.
Das Auflastgewicht kann fest mit dem Antriebsstrang oder der Fräswalze verbunden sein. Vorzugsweise ist es jedoch auswechselbar. Auf diese Weise lässt es sich dann an die Bodenbearbeitungsmaschine anbauen, wenn es speziell zum Zweck der gewünschten Laufruhe benötigt wird. Somit kann auch hier eine gewichtsoptimierte Anpassung der Maschine vorgenommen werden. Darüber hinaus vereinfacht sich auch der Maschinentransport, da das oder die Auflastgewichte separat gehandhabt, beispielsweise transportiert werden können. Zudem wird der Walzenwechsel vereinfacht, da eine leichtere Walze einfacher zu wechseln und handzuhaben ist.The load weight may be fixedly connected to the drive train or the milling drum. Preferably, however, it is interchangeable. In this way it can then be grown on the soil tillage machine when it is needed specifically for the purpose of the desired smoothness. Thus, a weight-optimized adaptation of the machine can also be made here. It also simplifies the machine transport, since the or the load weights separately handled, for example, can be transported. In addition, the roll change is simplified because a lighter roller is easier to change and handle.
Besonders bevorzugt ist es vorgesehen, dass wenigstens ein Auflastgewicht im Bereich der Fräswalze angeordnet ist. Hier ist das Auflastgewicht besonders effektiv einsetzbar, da es mit großem Abstand von der Drehachse angeordnet werden kann. Dies führt zu einer besonderen Steigerung der Laufruhe, da das Trägheitsmoment, und damit die kinetische Energie quadratisch vom Abstand der Masse zur Rotationsachse abhängen. Somit kann mit geringeren Auflastgewichten in großem Abstand zur Rotationsachse der gleiche Effekt erreicht werden wie mit großen Auflastgewichten in geringem Abstand zur Rotationsachse. Die Anordnung im Bereich der Fräswalze bringt auch Handhabungsvorteile. Insbesondere sind die Auflastgewichte hier gut zugänglich wenn sie auswechselbar angeordnet sind.It is particularly preferably provided that at least one load weight is arranged in the region of the milling drum. Here, the ballast weight can be used particularly effectively, since it can be arranged at a great distance from the axis of rotation. This leads to a particular increase in smoothness, since the moment of inertia, and thus the kinetic energy depend quadratically on the distance of the mass to the axis of rotation. Thus, with lower load weights at a large distance from the axis of rotation, the same effect can be achieved as with large load weights at a small distance from the axis of rotation. The arrangement in the area of the milling drum also brings handling advantages. In particular, the ballast weights are easily accessible here if they are interchangeable arranged.
Eine signifikante Steigerung der Laufruhe ergibt sich dann, wenn vorgesehen ist, dass das oder die Auflastgewichte eine Masse aufweisen, die geeignet ist, das Trägheitsmoment der Fräswalze um mindestens 10%, besonders bevorzugt um mindestens 20% zu erhöhen. Bei einer Erhöhung um mindestens 20% ergibt sich zudem der Vorteil, dass auch eine deutliche Entlastung des Maschinengewichts möglich ist. Ein Versuchsaufbau des Erfinders ergab dass eine Auflastung der Fräswalze um 100 kg eine Reduzierung des Gesamtmaschinengewichtes um 100 kg bei gleichbleibender Laufruhe ermöglicht.A significant increase in smoothness results when it is provided that the load or weights have a mass which is suitable for increasing the moment of inertia of the milling drum by at least 10%, particularly preferably by at least 20%. With an increase of at least 20%, there is also the advantage that a significant reduction in the weight of the machine is possible. An experimental set-up by the inventor showed that an increase of 100 kg in the milling drum enables a reduction of the total machine weight by 100 kg with a constant smoothness.
Eine denkbare Erfindungsvariante ist dergestalt, dass der Antriebsstrang und/oder die Fräswalze derart hergerichtet sind, dass mit den Auflastgewichten das Gewicht in zwei oder mehreren Stufen erhöht werden kann. Auf diese Weise lässt sich die Bodenbearbeitungsmaschine schrittweise an die gewünschte Arbeitsaufgabe anpassen. Darüber hinaus geht mit dieser Unterteilung der Auflastgewichte eine besonders einfache Handhabung einher.A conceivable variant of the invention is such that the drive train and / or the milling drum are prepared in such a way that with the load weights the weight can be increased in two or more stages. In this way, the soil tillage machine can be gradually adjusted to the desired work task. In addition, this subdivision of the load weights is accompanied by a particularly simple handling.
Eine erfindungsgemäße Bodenbearbeitungsmaschine kann dergestalt sein, dass am Antriebsstrang und/oder der Fräswalze Aufnahmen mit Befestigungsmitteln angeordnet sind mittels derer das oder die Auflastgewichte auswechselbar ankoppelbar sind. Auf diese Weise lassen sich die Auflastgewichte sicher und zuverlässig im rauen Baustellenbetrieb positionieren und befestigen. Die Auflastgewichte können hier beispielsweise von Segmenten oder Ringen oder dergleichen Baueinheiten gebildet sein.A tillage machine according to the invention may be such that receptacles are arranged on the drive train and / or the milling drum by means of which the load or weights can be interchangeably coupled. In this way, the load weights can be safely and reliably positioned and secured in rough construction site operation. The ballast weights can be formed here, for example, by segments or rings or similar units.
Besonders vorteilhaft ist es, wenn vorgesehen ist, dass das oder die Auflastgewichte in dem von dem Fräswalzenrohr umschlossenen Innenraum, vorzugsweise an der Innenseite des Fräswalzenrohrs angebracht sind. Dann sind die Auflastgewichte vor dem Angriff des Fräsguts auf einfache Art geschützt.It is particularly advantageous if it is provided that the load or weights are mounted in the space enclosed by the milling drum tube interior, preferably on the inside of the Fräswalzenrohrs. Then the load weights are protected from the attack of the milled material in a simple way.
Eine mögliche Erfindungsgestaltung kann dergestalt sein, dass das Auflastgewicht von einem Fluid gebildet ist, das in einem Fluidspeicher gehalten ist. Beispielsweise kann als Fluid Wasser eingesetzt werden. Dieses kann nach Gebrauch einfach wieder abgelassen werden.A possible inventive design may be such that the ballast weight is formed by a fluid held in a fluid reservoir. For example, water can be used as the fluid. This can easily be drained after use.
Erfindungsgemäß kann es auch vorgesehen sein, dass die Fräswalze mittels einer Befestigungsanordnung lösbar an Koppelstücken des Antriebsstranges montiert werden kann, und dass die Auflastgewichte an der Befestigungsanordnung auswechselbar angeordnet sind. Hier sind die Auflastgewichte insbesondere bei demontierter Fräswalze gut zugänglich.According to the invention it can also be provided that the milling drum can be detachably mounted on coupling pieces of the drive train by means of a fastening arrangement, and that the load weights are interchangeably arranged on the fastening arrangement. Here, the load weights are easily accessible, especially when the milling drum is disassembled.
Alternativ ist es möglich die Auflastgewichte zur Gewährleistung der einfachen Zugänglichkeit im axial äußeren Bereich der Fräswalze anzuordnen. Dadurch ergibt sich die Möglichkeit die Zusatzgewichte zu (de)montieren, ohne dass hierfür die Fräswalze vom Antriebsstrang abgebaut werden muss.Alternatively, it is possible to arrange the load weights to ensure easy accessibility in the axially outer region of the milling drum. This results the possibility of (additional) to assemble the additional weights, without that the milling drum must be removed from the drive train for this purpose.
Weiterhin ist es möglich die verschiedenen Befestigungsmöglichkeiten zu kombinieren, damit kann eine "kleine" Auflastung ohne großen Aufwand (bspw. ohne Demontage der Fräswalze) erfolgen. Sollte eine größere Auflastung angestrebt sein können darüber hinaus zusätzliche Gewichte im Inneren der Fräswalze nach deren Demontage befestigt werden.Furthermore, it is possible to combine the different mounting options, so that a "small" load without much effort (eg. Without disassembly of the milling drum) done. Should a greater load be sought, additional weights can be mounted inside the milling drum after disassembly.
Insgesamt empfiehlt es sich zu Gunsten einer hohen Laufruhe die mit dem oder den Auflastgewichten bestückte, rotierende Komponente, beispielsweise die Fräswalze derart zu gestalten, dass sie ausgewuchtet ist. Zur Vermeidung von Unwuchten empfiehlt es sich hierzu beispielsweise auch die Auflastgewichte symmetrisch verteilt anzuordnen.Overall, it is recommended in favor of a high degree of smoothness equipped with the or the load weights, rotating component, such as the milling drum to make such that it is balanced. To avoid imbalances, it is advisable for this purpose, for example, to arrange the load weights symmetrically distributed.
Eine denkbare Erfindungsgestaltung ist derart, dass als Auflastgewicht eine ausgehärtete Gussmasse, vorzugsweise Beton, verwendet ist. Mit dieser Maßnahme lässt sich die Auflastung kostengünstig und auf einfache Weise wirkungsvoll vornehmen.A conceivable embodiment of the invention is such that a hardened casting compound, preferably concrete, is used as a load-on weight. With this measure, the charge can be made inexpensively and easily effective.
Die erfindungsgemäße Auflastung ist nicht alleine bei mechanischen Antrieben mit Verbrennungsmotor möglich. Vielmehr ist eine Auflastung auch bei anderen Antriebsvarianten der Fräswalze möglich. Beispielsweise ist es denkbar hydraulische oder elektrische Fräswalzenantriebe an deren rotierenden Komponenten und/oder der Fräswalze aufzulasten, wobei die gleichen Vorteile erzielt werden können.The charge according to the invention is not possible alone with mechanical drives with an internal combustion engine. Rather, an increase in other drive variants of the milling drum is possible. For example, it is conceivable to load hydraulic or electric milling drum drives on their rotating components and / or the milling drum, wherein the same advantages can be achieved.
