  • the Fräswalzengeophene is almost flush with an end face with an outside of the machine frame, the so-called zero side to allow the closest possible milling along edges or obstacles.
  • the Fräswalzengeophuse is not height adjustable relative to the machine frame, so that the full machine weight can be transferred to the milling drum to allow high cutting forces and thus a high milling depth.
  • the neutral side of a road milling machine is preferably arranged on the right-hand side of the machine in the direction of travel.

Als Großfräsen werden beispielsweise Straßenfräsmaschinen mit einer Fräsbreite ca. 1500 mm und darüber bezeichnet. Derartige Straßenfräsmaschinen haben ein hohes Gewicht und werden daher in der Regel von einem Fahrwerk mit Kettenlaufwerken getragen. Die Fräswalze ist an dem Maschinenrahmen zwischen den Kettenlaufwerken der Vorderachse und der Hinterachse gelagert, und zwar mit Abstand von diesen. Großfräsen haben ein höhenverstellbares Fahrwerk mit in Fahrtrichtung vorderen und hinteren Laufwerken, die die Vorderachse bzw. die Hinterachse bilden. Der Maschinenrahmen wird von dem Fahrwerk getragen, wobei zwischen den Achsen der vorderen und hinteren Laufwerke ein Fräswalzengehäuse am Maschinenrahmen angeordnet ist, das eine einzige, in dem Fräswalzengehäuse drehbar gelagerte Fräswalze aufweist. An dem Fräswalzengehäuse ist mit Hilfe eines Bandschuhs eine Transportbandeinrichtung zum Abtransport des von der Fräswalze abgearbeiteten und ausgeworfenen Fräsgutes in Fahrtrichtung nach vorne gekoppelt.As large milling machines, for example, road milling machines with a milling width of about 1500 mm and above are referred to. Such road milling machines have a high weight and are therefore usually carried by a chassis with crawler tracks. The milling drum is mounted on the machine frame between the crawlers of the front axle and the rear axle, at a distance from them. Large milling machines have a height-adjustable chassis with front and rear drives in the direction of travel, which form the front axle and the rear axle. The machine frame is carried by the landing gear, wherein between the axes of the front and rear drives a Fräswalzengehäuse is arranged on the machine frame having a single, rotatably mounted in the Fräswalzengehäuse milling drum. At the milling drum housing, a conveyor belt device for transporting the milling material processed and ejected from the milling drum is coupled in the direction of travel forward with the aid of a belt shoe.

Eine derartige Großfräse ist beispielsweise aus der EP 2 011 921 A bekannt.Such a large milling machine is for example from the EP 2 011 921 A known.

Das Fräswalzengehäuse ist mit einer Stirnseite nahezu bündig mit einer Außenseite des Maschinenrahmens, der sogenannten Nullseite, um ein möglichst nahes Fräsen entlang von Kanten oder Hindernissen zu ermöglichen. Das Fräswalzengehäuse ist relativ zum Maschinenrahmen nicht höhenverstellbar, so dass das vollständige Maschinengewicht auf die Fräswalze übertragen werden kann, um hohe Schnittkräfte und damit eine hohe Frästiefe zu ermöglichen.The Fräswalzengehäuse is almost flush with an end face with an outside of the machine frame, the so-called zero side to allow the closest possible milling along edges or obstacles. The Fräswalzengehäuse is not height adjustable relative to the machine frame, so that the full machine weight can be transferred to the milling drum to allow high cutting forces and thus a high milling depth.

Großfräsen sind u. a. wegen ihrer eingeschränkten Manövrierfähigkeit bisher hauptsächlich nur zum Bearbeiten großer Flächen eingesetzt worden, wobei entsprechend dem Straßenverlauf auch Straßenkurven mit einem großen Kurvenradius bearbeitet werden konnten.Large milling machines are u. a. because of their limited maneuverability so far mainly been used only for processing large areas, which also road curves with a large radius of curvature could be edited according to the road.

Insbesondere bei Fräsarbeiten, die relativ zur Nullseite nach innen führen, besteht bei Großfräsen das Problem, dass der Fahrzeugführer nicht exakt einer vorgegebenen Kurvenlinie mit einem engen Kurvenradius folgen konnte. Hierzu ist in der EP 2 011 921 eine Lösung entnehmbar, durch die eine Sichtkontrolle für die Lenkung einer Großfräse ermöglicht worden ist, wodurch die Manövrierfähigkeit einer Großfräse verbessert werden konnte.Particularly in the case of milling operations which lead inwards relative to the neutral side, there is the problem with large milling machines that the driver could not exactly follow a predetermined curve line with a tight curve radius. This is in the EP 2 011 921 a solution was removed, through which a visual inspection has been made possible for the steering of a large milling machine, whereby the maneuverability of a large milling machine could be improved.

Bei Straßen mit Rechtsverkehr ist die Nullseite einer Straßenfräsmaschine vorzugsweise auf der in Fahrtrichtung rechten Seite der Maschine angeordnet. Bei Straßen mit Linksverkehr befindet sich die Nullseite vorzugsweise auf der (in Fahrtrichtung) linken Seite. Es versteht sich, dass eine Großfräse, wenn genügend Platz für ein Wendemanöver besteht, auch gewendet werden kann und somit auch eine Großfräse mit der Nullseite auf der in Fahrtrichtung rechten Seite für Straßen mit Linksverkehr verwendet werden kann. Dies hat den Nachteil, dass die Straßenfräsmaschine, die ihre Nullseite auf der in Fahrtrichtung rechten Seite hat, gegen den fließenden Verkehr fahren muss, wenn eine Straße während des Betriebs nicht vollständig gesperrt werden kann. Eine solche Situation tritt beispielsweise auf, wenn auf einer Autobahn die linke Fahrspur bündig mit der linken Straßenseite gefräst werden soll. Nachteilig ist dabei, dass auch die Lastkraftwagen, die das Fräsgut vor der Straßenfräsmaschine aufnehmen, entgegen dem Verkehrsfluss vor die Straßenfräsmaschine fahren müssen und von dort wieder wegfahren müssen. Aber auch im Fall von engen Straßen besteht häufig der Wunsch, die Straße wahlweise auf der linken oder der rechten Seite bündig bearbeiten zu können, ohne die Großfräse wenden zu müssen.For right-hand traffic, the neutral side of a road milling machine is preferably arranged on the right-hand side of the machine in the direction of travel. On roads with left-hand traffic, the null side is preferably on the left (in the direction of travel). It is understood that a large milling machine, if there is enough space for a turning maneuver can also be turned and thus a large milling machine with the zero side on the right in the direction of travel can be used for roads with left-hand traffic. This has the disadvantage that the road milling machine, which has its zero side on the right in the direction of travel, must drive against the flowing traffic, if a road during operation can not be completely disabled. Such a situation occurs, for example, when the left lane is to be milled flush with the left side of the road on a highway. The disadvantage here is that even the trucks that receive the milled material in front of the road milling machine, contrary have to drive the traffic flow in front of the road milling machine and have to drive away from there again. But even in the case of narrow streets is often the desire to edit the road either on the left or the right side flush, without having to turn the large milling machine.

Hierzu ist es beispielsweise aus der DE 83 15 139 U bei einer von einem Räderfahrwerk getragenen Straßenfräsmaschine vorgesehen, eine einzige hydraulisch angetriebene Fräswalze quer zur Fahrtrichtung, längs von Gleitführungen um einen geringen Hub zu verschieben. Es handelt sich nicht um eine Großfräse, mit der hohe Schnittkräfte verwirklicht werden können, da die Fräswalze um eine horizontale Achse schwenkbar gelagert ist und lediglich durch ihr Eigengewicht auf dem Boden aufliegt. Die Fräswalze ist daher relativ zum Maschinenrahmen anheb- oder absenkbar und kann zusätzlich um eine in Fahrzeugrichtung verlaufende Achse verschwenkt werden, um sich der Straßenneigung anzupassen. Die Querverschieblichkeit soll eine genaue Steuerung der Frässpur ermöglichen. Es versteht sich, dass aufgrund dieser pendelnden Lagerung der Fräswalze keine hohen Schnittkräfte aufgebracht werden können und eine derartige Fräse nur für ein Oberflächenfräsen ohne hohe Frästiefen geeignet ist.For this it is for example from the DE 83 15 139 U provided in a road milling machine carried by a wheel gear, to move a single hydraulically driven milling drum transversely to the direction of travel, along sliding guides to a small stroke. It is not a large milling machine, with the high cutting forces can be realized because the milling drum is mounted pivotably about a horizontal axis and rests only by its own weight on the ground. The milling drum can therefore be raised or lowered relative to the machine frame and can additionally be pivoted about an axis extending in the vehicle direction in order to adapt to the road incline. The Querverschieblichkeit should allow precise control of the milling track. It is understood that due to this oscillating mounting of the milling drum no high cutting forces can be applied and such a router is only suitable for surface milling without high cutting depths.

Aus der US 3767262 ist eine Straßenfräsmaschine mit einer sich im Wesentlichen über die gesamte Arbeitsbreite der Maschine erstreckenden Fräswalze bekannt, die um einen Kurvenradius einer Fräsbahn zu reduzieren, zur kurveninneren Seite in eine Außenposition über die Außenkontur der Maschine hinaus verlagerbar ist.From the US 3767262 is a road milling machine with a substantially over the entire working width of the machine extending milling drum is known, which is to reduce the curve radius of a cutting path to the inside of the curve in an outward position beyond the outer contour of the machine out.

Auch diese Straßenfräsmaschine ist keine Großfräse, mit der hohe Schnittkräfte realisiert werden können, da die Fräswalze gegenüber dem Maschinenrahmen höhenverstellbar ist und sich nicht unmittelbar an dem Maschinenrahmen vertikal starr abstützen kann.This road milling machine is not a large milling machine, with the high cutting forces can be realized because the milling drum relative to the machine frame is height adjustable and can not support vertically rigidly directly to the machine frame.

Weiterhin ist aus der EP 0 752 501 eine Straßenfräsmaschine mit einer rotierenden Fräswalze zum Fräsen von Rillen oder Schlitzen in Straßenoberflächen bekannt. Die Fräswalze ist dabei am hinteren Ende der Straßenfräsmaschine querverschieblich unter einem Schienensystem aufgehangen. Die Fräswalze kann entlang des Schienensystems außerhalb des Fräsbetriebs querverschoben werden und wird über ein Verriegelungssystem während des Fräsbetriebs in einer von mehreren Positionen arretiert.Furthermore, from the EP 0 752 501 a road milling machine with a rotating milling drum for milling grooves or slots in road surfaces known. The milling drum is suspended at the rear end of the road milling machine transversely displaceable under a rail system. The milling drum can be transversely displaced along the rail system outside of the milling operation and is locked in one of several positions via a locking system during milling operation.

Der Erfindung liegt die Aufgabe zugrunde, eine selbstfahrende Großfräse der eingangs genannten Art, sowie ein Verfahren zum Bearbeiten von Straßenoberflächen zu schaffen, die universeller einsetzbar ist und deren Manövrierfähigkeit verbessert ist.The invention has for its object to provide a self-propelled large milling machine of the type mentioned, and a method for editing road surfaces, which is universally applicable and their maneuverability is improved.

Zur Lösung dieser Aufgabe dienen die Merkmale des Anspruchs 1 bzw. 14.To solve this problem serve the features of claim 1 and 14th

Die Erfindung sieht in vorteilhafter Weise vor, dass der Fräswalzenantrieb ein in die Fräswalze integrierter hydraulischer oder elektrischer Antrieb ist, und dass die Fräswalze gemeinsam mit dem in Höhenrichtung und in Fahrtrichtung starr an dem Maschinenrahmen befestigten Fräswalzengehäuse und mit dem Fräswalzenantrieb quer zur Fahrtrichtung am Maschinenrahmen verschiebbar gelagert ist, wodurch wahlweise die Nullseite auf der einen Außenseite oder auf der gegenüberliegenden Außenseite des Maschinenrahmens festlegbar ist und wobei an den Stirnkanten der Fräswalze zusätzliche Meißelwerkzeuge zum Querverschieben der Fräswalze während des Fräsbetriebes vorgesehen sind.The invention advantageously provides that the milling drum drive is a hydraulic or electric drive integrated in the milling drum, and that the milling drum is displaceable transversely to the direction of travel on the machine frame together with the milling drum housing fixed rigidly to the machine frame in the vertical direction and in the direction of travel is mounted, whereby optionally the zero side on the one outer side or on the opposite outer side of the machine frame can be fixed and wherein at the front edges of the milling drum additional chisel tools for transversely displacing the milling drum are provided during the milling operation.

Die erfindungsgemäße Lösung hat den Vorteil, dass im Wesentlichen das gesamte Maschinengewicht aufgrund der Anordnung der Fräswalze zwischen den Achsen des Fahrwerks auf die Fräswalze einwirkt, wodurch große Frästiefen bei hohen Vortriebsgeschwindigkeiten möglich sind. Durch die Verschiebbarkeit der Fräswalze kann die Nullseite wahlweise auf der einen Außenseite oder auf die gegenüberliegende Außenseite festgelegt werden, so dass unter Beibehaltung der Fahrtrichtung wahlweise links- oder rechtsbündig entlang von Hindernissen gearbeitet werden kann. Dabei kann erfindungsgemäß die Fräswalze auch während des Fräsbetriebes verschoben werden, wozu die Fräswalze an ihren Stirnkanten die zusätzlichen Meißelwerkzeuge aufweist. Die Fräswalze wird gemeinsam mit dem Fräswalzengehäuse und dem in die Fräswalze integrierten Fräswalzenantrieb linear und quer zur Fahrtrichtung am Maschinenrahmen verschoben. Die lineare Führung unterhalb des Maschinenrahmens hat den Vorteil, dass weder die Frästiefe noch die Querneigung der Fräswalze durch die Linearverschiebung beeinflusst wird. Dies ist von Bedeutung bei der Nivellierung der Großfräse mit Hilfe eines höhenverstellbaren Fahrwerks. Ein wesentlicher Vorteil ist dabei, dass nur die Lage des Maschinenrahmens überwacht werden muss, um ggf. Korrekturen durchführen zu können. Ein weiterer Vorteil besteht darin, dass die Fräswalze während des Betriebes verschoben werden kann, ohne dass eine Betriebsunterbrechung erforderlich wäre.The solution according to the invention has the advantage that substantially the entire weight of the machine due to the arrangement of the milling drum between the axes of the landing gear acts on the milling drum, whereby large cutting depths are possible at high speeds propulsion. Due to the displaceability of the milling drum, the zero side can be set either on the one outer side or on the opposite outer side, so that while maintaining the direction of travel either left or right-aligned along obstacles can be worked. In this case, according to the invention, the milling drum can also be moved during the milling operation, for which purpose the milling drum has the additional chisel tools at its end edges. The milling drum is moved linearly with the milling drum housing and the milling drum drive integrated into the milling drum and transversely to the direction of travel on the machine frame. The linear guide below the machine frame has the advantage that neither the milling depth nor the bank of the milling drum is influenced by the linear displacement. This is important when leveling the large milling machine with the aid of a height-adjustable chassis. A significant advantage is that only the position of the machine frame must be monitored in order to be able to carry out corrections if necessary. Another advantage is that the milling drum can be moved during operation without interrupting the operation.

Die Frästiefe kann über das höhenverstellbare Fahrwerk eingestellt werden. Die hohe Druckbelastung der Fräswalze über den Maschinenrahmen in Verbindung mit dem Fräswalzengehäuse ermöglicht Frästiefen von mindestens 30 cm, so dass in einer einzigen Überfahrt die gesamte Straßendecke entfernt werden kann.The milling depth can be adjusted via the height-adjustable chassis. The high pressure load of the milling drum on the machine frame in conjunction with the milling drum housing allows milling depths of at least 30 cm, so that in a single crossing the entire road surface can be removed.

Die Abkehr von dem üblichen mechanischen Antriebskonzept mit einem Riemenantrieb und die Integration von vorzugsweise zwei Motoren in die Fräswalze ermöglichen es, die Lage der Fräswalze quer zur Fahrtrichtung zu variieren.The departure from the usual mechanical drive concept with a belt drive and the integration of preferably two motors in the milling drum make it possible to vary the position of the milling drum transversely to the direction of travel.

Der Fräswalzenantrieb erfolgt vorzugsweise beidseitig, also mit zwei in den Stirnseiten der Fräswalze integrierten Antriebseinrichtungen.The milling roller drive is preferably carried out on both sides, ie with two integrated in the end faces of the milling drum drive means.

Vorzugsweise ist vorgesehen, dass die lineare Verschiebung der Fräswalzengehäuses entlang von zwei linearen, in Fahrtrichtung des Maschinenrahmens beabstandeten Führungen erfolgt.It is preferably provided that the linear displacement of the Fräswalzengehäuses along two linear, spaced in the direction of travel of the machine frame guides takes place.

Die zwei linearen Führungen bewirken eine steife Lagerung des Fräswalzengehäuses am Maschinenrahmen und damit auch eine steife Lagerung der Fräswalze in vertikaler Richtung, so dass eine präzise Frästiefeneinstellung erhalten bleibt. Desweiteren ist die Lagerung des Fräswalzengehäuses in Fahrtrichtung steif, so dass eine Beweglichkeit der Fräswalze nur in Querrichtung zur Fahrtrichtung besteht.The two linear guides cause a stiff mounting of the milling drum housing on the machine frame and thus also a rigid mounting of the milling drum in the vertical direction, so that a precise routing depth adjustment is maintained. Furthermore, the storage of the Fräswalzengehäuses in the direction of travel is stiff, so that a mobility of the milling drum is only in the transverse direction to the direction of travel.

Eine erste der linearen Führungen ist eine Rohrführung und bildet ein Festlager und eine zweite der linearen Führungen ist eine Führung zwischen ebenen Flächen und bildet ein Loslager.A first of the linear guides is a pipe guide and forms a fixed bearing and a second of the linear guides is a guide between flat surfaces and forms a floating bearing.

Die Lagerung des Fräswalzengehäuses weist demzufolge ein Festlager und ein Loslager auf, wobei das Spiel zwischen den ebenen Flächen des Loslagers einstellbar sein kann.The storage of the Fräswalzengehäuses therefore has a fixed bearing and a movable bearing, wherein the game between the flat surfaces of the movable bearing can be adjustable.

Vorzugsweise ist vorgesehen, dass die linearen Führungen unterhalb des Maschinenrahmens an dem Maschinenrahmen befestigt sind.It is preferably provided that the linear guides are fastened below the machine frame to the machine frame.

Die Anordnungen der Linearführungen unterhalb des Maschinenrahmens haben den Vorteil, dass die Gewichtskraft der Maschine unmittelbar über das Fräswalzengehäuse auf die Fräswalze übertragen werden kann, und dass die Führungen platzsparend angeordnet werden können.The arrangements of the linear guides below the machine frame have the advantage that the weight of the machine can be transferred directly to the milling drum via the milling drum housing, and that the guides can be arranged to save space.

Das Fräswalzengehäuse ist dabei in Höhenrichtung und in Fahrtrichtung starr an dem Maschinenrahmen befestigt.The Fräswalzengehäuse is fixed in the vertical direction and in the direction of travel rigidly to the machine frame.

Das Fräswalzengehäuse weist an den Stirnseiten jeweils ein höhenverstellbares Seitenschild auf. Der Schnittkreis an den Stirnseiten der Fräswalze beim Fräsen entlang eines Hindernisses, z.B. einer Laterne oder eines Brückenpfeilers, hat vorzugsweise einen Abstand von dem Hindernis von weniger als 120 mm, vorzugsweise von 105 mm, oder weniger als 105 mm.The milling drum housing has at the end faces in each case a height-adjustable side plate. The cutting circle at the end faces of the milling drum when milling along an obstacle, for example a lantern or a bridge pier, preferably has a distance from the obstacle of less than 120 mm, preferably 105 mm, or less than 105 mm.

Der maximale seitliche Verfahrweg der Fräswalze beträgt zwischen 500 und 1000 mm. Dieser Verfahrweg ermöglicht es, wahlweise die Nullseite auf der linken oder rechten Seite der Straßenfräsmaschine festzulegen.The maximum lateral travel of the milling drum is between 500 and 1000 mm. This travel makes it possible to optionally set the zero side on the left or right side of the road milling machine.

Die Fräswalze ist vorzugsweise beidseitig hydraulisch antreibbar. Der beidseitige Antrieb hat den Vorteil, dass die Torsionsbelastung der Fräswalze reduziert werden kann, und dass letztlich eine höhere Leistung auf die Fräswalze übertragen werden kann. Alternativ ist ein elektrischer Antrieb möglich.The milling drum is preferably hydraulically driven on both sides. The two-sided drive has the advantage that the torsional load of the milling drum can be reduced, and that ultimately a higher power can be transferred to the milling drum. Alternatively, an electric drive is possible.

An dem Fräswalzengehäuse kann ein Bandschuh zur Aufnahme des unteren Endes der Transportbandeinrichtung höhenverstellbar befestigt sein. Der Bandschuh kann der Bewegung des Fräswalzengehäuses quer zur Fahrtrichtung folgen, so dass das untere Ende der Transportbandeinrichtung stets an der Auswurföffnung für das Fräsgut am Fräswalzengehäuse angeordnet ist.At the Fräswalzengehäuse a band shoe for receiving the lower end of the conveyor belt device can be fixed in height adjustable. The belt shoe can follow the movement of the milling drum housing transversely to the direction of travel, so that the lower end of the conveyor belt device is always arranged at the discharge opening for the milled material on the milling drum housing.

Hierzu ist vorgesehen, dass die Transportbandeinrichtung gelenkig mit dem Bandschuh verbunden ist.For this purpose, it is provided that the conveyor belt device is pivotally connected to the belt shoe.

Der Bandschuh weist zur gelenkigen Aufnahme des unteren Endes der Transportbandeinrichtung eine im Wesentlichen konkave, vorzugsweise sphärische Aufnahmepfanne auf, die mit einer der Form der Aufnahmepfanne angepassten Unterseite des unteren Endes der Transportbandeinrichtung zusammenwirkt.The belt shoe has for the articulated receiving of the lower end of the conveyor belt device on a substantially concave, preferably spherical receiving socket, which cooperates with a shape adapted to the receiving pan bottom of the lower end of the conveyor belt device.

Das vordere Ende der Transportbandeinrichtung am Maschinenrahmen ist entlang der Längsachse der Transportbandeinrichtung längsverschiebbar und kardanisch gelagert.The front end of the conveyor belt device on the machine frame is longitudinally displaceable and gimbaled along the longitudinal axis of the conveyor belt device.

Die Transportbandeinrichtung ist am vorderen Ende um eine bei horizontaler Ausrichtung des Maschinenrahmens vertikale Hochachse sowie eine parallel zur Fräswalzenachse verlaufende Querachse schwenkbar.The conveyor belt device is pivotable at the front end about a horizontal axis of the machine frame vertical vertical axis and a parallel to the Fräswalzenachse transverse axis.

Die Transportbandeinrichtung weist zur beweglichen Lagerung zumindest am vorderen Ende an der Unterseite ein im Wesentlichen in Längsrichtung der Transportbandeinrichtung verlaufendes transportbandseitiges Stützelement mit vorzugsweise konvexer Auflagerfläche auf, das seitlich geführt auf einem quer zur Fahrtrichtung am Maschinenrahmen befestigten rahmenseitigen Stützelement mit vorzugsweise konvexer Stützfläche aufliegt. Die Auflagefläche und die Stützflächen bilden ein kardanisches Gelenk, wobei der zusätzliche Vorteil besteht, dass auch ein geringfügiges Rollen um die Längsachse der Transportbandeinrichtung möglich ist.The conveyor belt device has for movable mounting at least at the front end on the underside a substantially in the longitudinal direction of the conveyor belt device extending conveyor belt side support member with preferably convex bearing surface laterally guided on a transverse fixed to the direction of travel on the machine frame frame-side support member rests with preferably convex support surface. The support surface and the support surfaces form a gimbal joint, with the additional advantage that even a slight rolling around the longitudinal axis of the conveyor belt device is possible.

Das transportbandseitige Stützelement und/oder das rahmenseitige Stützelement können aus einem im Querschnitt gerundeten Profil oder Hohlprofil gebildet sein. Diese können in vorteilhafter Weise aufeinander aufliegen und somit eine punktförmige Lagerung ermöglichen, die eine Verschiebung der Transportbandeinrichtung in ihrer Längsachse zulässt.The conveyor belt-side support member and / or the frame-side support member may be formed from a rounded profile or hollow profile. These can advantageously rest on one another and thus enable point-like storage, which permits a displacement of the conveyor belt device in its longitudinal axis.

Der Bandschuh ist vorzugsweise über eine Gleichlaufführung höhenverstellbar. Dabei erfolgt die Führung des Bandschuhs zum Anheben und Absenken in einer Art Linearführung, bei der die Höhenverstellung auf der rechten und linken Seite des Bandschuhs um den gleichen Betrag synchron erfolgt.The belt shoe is preferably height adjustable via a synchronous guide. The leadership of the belt shoe for raising and lowering in a kind of linear guide, in which the height adjustment takes place synchronously on the right and left side of the belt shoe by the same amount.

An dem Fräswalzengehäuse kann ortsfest ein Hydraulikwinkelverteiler zum Versorgen der an dem Fräswalzengehäuse vorgesehenen hydraulischen Antriebe, zumindest der Fräswalzenantriebe, angeordnet sein.A hydraulic angle distributor for supplying the hydraulic drives provided on the milling drum housing, at least the milling drum drives, can be stationarily arranged on the milling drum housing.

Der ortsfest an dem Fräswalzengehäuse angeordnete Hydraulikwinkelverteiler ermöglicht es, dass die Hydraulikleitungen auf dem Fräswalzengehäuse zu den Antrieben starr ausgeführt werden können und verhindern zu enge Biegeradien der Zuleitungen von den Hydraulikpumpen.The fixedly arranged on the Fräswalzengehäuse hydraulic angle distributor makes it possible that the hydraulic lines can be performed rigidly on the Fräswalzengehäuse to the drives and prevent tight bending radii of the leads from the hydraulic pumps.

Zur Verbesserung der Manövrierfähigkeit und zur universellen Verwendbarkeit einer Großfräse kann auch vorgesehen sein, dass das in Fahrtrichtung hintere Ende des Fräswalzengehäuses mit einem höhenverstellbaren Abstreiferschild abschließt, der seitlich in der Frässpur der Fräswalze federnd gegen die zur Straßenoberfläche orthogonalen Fräskanten der Frässpur anliegt.To improve the maneuverability and universal applicability of a large milling machine can also be provided that the rear end in the direction of travel of the Fräswalzengehäuses concludes with a height-adjustable wiper blade, which rests laterally in the milling track of the milling roller resiliently against the road surface orthogonal Fräskanten the milling track.

Dadurch, dass der Abstreiferschild seitlich einfedern kann, kann die Großfräse enge Kurvenradien fahren, ohne dass sich der Abstreiferschild verkantet. Ein weiterer Vorteil besteht darin, dass der Abstreiferschild durch das elastische Anliegen des Abstreiferschildes gegen die Fräskante der Frässpur die Frässpur ohne Fräsgutrückstände abziehen kann.Due to the fact that the scraper blade can deflect laterally, the large milling machine can drive tight curve radii without the scraper blade tilting. Another advantage is that the wiper blade by the elastic concern of the scraper blade against the milling edge of the milling track can pull off the milling track without milled material residues.

Dabei kann das in Fahrtrichtung hintere Ende des Fräswalzengehäuses mit einem höhenverstellbaren Abstreiferschild abschließen, der an beiden seitlichen Enden jeweils ein bewegliches Schildelement aufweist, das an der Unterkante im Wesentlichen bündig mit dem Abstreiferschild abschließt und mit diesem gemeinsam höhenverstellbar ist, wobei die Schildelemente parallel zu dem Abstreiferschild und der Fräswalzenachse gegen eine Federvorspannung zur dynamischen Anpassung der Abstreiferschildbreite während des Fräsens verstellbar sind.The rear end of the milling drum housing in the direction of travel can conclude with a height-adjustable scraper blade, which has at both lateral ends in each case a movable shield element which is substantially flush with the scraper blade at the lower edge and height-adjustable together with the latter, wherein the shield elements are parallel to the Scraper blade and the Fräswalzenachse are adjustable against a spring preload for dynamic adjustment of the Abstreiferschildbreite during milling.

Ein solcher Abstreiferschild mit seitlichen beweglichen Schildelementen hat den Vorteil, dass die Schildbreite sich dynamisch an die Frässpur anpasst. Dies ist insbesondere von Vorteil bei engen Kurvenfahrten mit Großfräsen, aber auch wenn sich die Frässpur in Querrichtung zur Fahrtrichtung aufgrund einer gesteuerten Querbewegung des Fräswalzengehäuses verlagert.Such a scraper blade with side movable shield elements has the advantage that the blade width adapts dynamically to the milling track. This is particularly advantageous for tight turns with large milling machines, but also when the milling track moves in the transverse direction to the direction of travel due to a controlled transverse movement of the Fräswalzengehäuses.

Die Federvorspannung wird vorzugsweise hydraulisch erzeugt und kann auch hinsichtlich der Höhe der Vorspannung einstellbar vorgesehen sein. Alternativ kann die Federvorspannung mechanisch oder mit einer Gasfeder erzeugt werden. Bei einem Verfahren zum Bearbeiten von Straßenoberflächen, mit einer selbstfahrenden Großfräse mit einem Maschinenrahmen mit seitlichen Außenseiten, mit einer einzigen drehbar gelagerten Fräswalze, und mit einem Fräswalzenantrieb für die Fräswalze, bei dem die Fräswalze mit einer Stirnseite nahezu bündig mit einer seitlichen Außenseite des Maschinenrahmens, der sogenannten Nullseite, abschließt, um ein möglichst nahes Fräsen entlang von Kanten oder Hindernissen zu ermöglichen ist vorgesehen, dass wahlweise die Nullseite auf der einen Außenseite oder auf der gegenüberliegenden Außenseite des Maschinenrahmens festlegt wird, indem der Fräswalzenantrieb in die Fräswalze als hydraulischer oder elektrischer Antrieb integriert wird und die Fräswalze gemeinsam mit dem Fräswalzenantrieb quer zur Fahrtrichtung verschiebbar gelagert wird, wobei zum Verschieben der Fräswalze während des Fräsbetriebes zusätzliche Meißelwerkzeuge an den Stirnkanten der Fräswalze vorgesehen sind.The spring preload is preferably generated hydraulically and may also be provided adjustable in terms of the amount of bias. Alternatively, the spring preload can be generated mechanically or with a gas spring. In a method for processing road surfaces, with a self-propelled large milling machine with a machine frame with lateral outsides, with a single rotatably mounted milling drum, and with a milling drum drive for the milling drum, wherein the milling drum with an end face almost flush with a lateral outside of the machine frame, the so-called zero side closes, in order to allow the closest possible milling along edges or obstacles is provided that optionally the zero side is fixed on the one outer side or on the opposite outer side of the machine frame by the Fräswalzenantrieb in the milling drum as a hydraulic or electric drive is integrated and the milling drum is mounted displaceably transversely to the direction of travel together with the milling drum drive, wherein for moving the milling drum during the milling operation additional chisel tools provided on the front edges of the milling drum are.

Im Folgenden wird unter Bezugnahme auf die Zeichnungen ein Ausführungsbeispiel der Erfindung näher erläutert:An embodiment of the invention will be explained in more detail below with reference to the drawings.

Fig. 1 zeigt eine Großfräse 1 mit einem Maschinenrahmen 8 und einem Fahrwerk 4 mit in Fahrtrichtung 31 vorderen und hinteren Laufwerken 5,6. Die Laufwerke 5,6 bilden eine lenkbare Vorderachse und lenkbare Hinterachse. Das Fahrwerk 4 ist über Hubsäulen 7 mit dem Maschinenrahmen 8 verbunden, mit deren Hilfe der Abstand des Maschinenrahmens 8 von einer Straßenoberfläche 2 einstellbar ist. Jede Fahrwerksachse weist mindestens ein Kettenlaufwerk 5,6 oder ein Radlaufwerk auf. Fig. 1 shows a large milling machine 1 with a machine frame 8 and a chassis 4 with in the direction of travel 31 front and rear drives 5.6. The drives 5.6 form a steerable front axle and steerable rear axle. The chassis 4 is connected via lifting columns 7 with the machine frame 8, by means of which the distance of the machine frame 8 from a road surface 2 is adjustable. Each chassis axle has at least one track drive 5, 6 or a wheel drive.

Am in Fahrtrichtung vorderen Ende der Großfräse 1 ist eine in Höhen- und Seitenrichtung schwenkbare Transportbandeinrichtung 18 zum Abtransport des abgefrästen Fräsgutes angeordnet.At the front end of the large milling machine 1 in the direction of travel, a conveyor belt device 18, which is pivotable in the vertical and lateral direction, is arranged for the removal of the milled material to be milled.

Die vorderen und die hinteren Laufwerke 5,6 des Fahrwerks 4 können aus Kettenlaufwerken oder Rädern bestehen.The front and rear drives 5,6 of the chassis 4 may consist of crawler tracks or wheels.

Der Maschinenrahmen 8 weist im Wesentlichen vertikal und parallel zur Längsmittelachse der Straßenbaumaschine 1 verlaufende seitliche Außenseiten 26,28 auf. Es versteht sich, dass die Außenseiten 26,28 nicht streng vertikal und absolut parallel zur Längsmittelachse der Großfräse 1 verlaufen müssen, sondern dass geringfügige Abweichungen möglich sind. Die Außenseite 26,28 ist vorzugsweise einstückig gefertigt, wobei die Außenseiten 26 und 28 vorzugsweise in einer Ebene liegen.The machine frame 8 has substantially vertically and parallel to the longitudinal center axis of the road construction machine 1 extending lateral outer sides 26,28. It is understood that the outer sides 26,28 do not have to be strictly vertical and absolutely parallel to the longitudinal center axis of the large milling machine 1, but that slight deviations are possible. The outer side 26,28 is preferably made in one piece, wherein the outer sides 26 and 28 are preferably in a plane.

Zwischen den Laufwerken 5,6 ist eine Fräswalze 12 angeordnet, die mit ihrer Fräswalzenachse in einem Fräswalzengehäuse 10 gelagert ist.Between the drives 5.6 a milling drum 12 is arranged, which is mounted with its Fräswalzenachse in a Fräswalzengehäuse 10.

Die Fräswalze 12 reicht mit ihrer einen Stirnseite 22 bis an die in Fig. 1 als Nullseite dargestellte Außenseite 26,28 des Maschinenrahmens 8 heran. Auf der Nullseite befindet sich die entsprechende Stirnseite 22 der Fräswalze sehr nah an der Außenseite der Großfräse 1, so dass sehr eng an Straßenkanten oder Hindernissen vorbei gefräst werden kann.The milling drum 12 extends with its one end face 22 to the in Fig. 1 shown as zero side outside 26,28 of the machine frame 8 zoom. On the null side, the corresponding end face 22 of the milling drum is very close to the outside of the large milling machine 1, so that it can be milled very closely past road edges or obstacles.

In die Stirnseite 22 der Fräswalze 12 sind vorzugsweise auf beiden Seiten hydraulische oder elektrische Fräswalzenantriebe 14 integriert, die von auf dem Maschinenrahmen 8 angeordneten Hydropumpen bzw. Generatoren versorgt werden, die ihrerseits von einem Verbrennungsmotor 3 angetrieben werden, der die Antriebsenergie für den Fahrantrieb, den Fräsantrieb und für Nebenaggregate zur Verfügung stellt.In the end face 22 of the milling drum 12 hydraulic or electric Fräswalzenantriebe 14 are preferably integrated on both sides, which are supplied by arranged on the machine frame 8 hydraulic pumps or generators, which in turn are driven by an internal combustion engine 3, the drive energy for the traction drive, the Milling drive and ancillary equipment provides.

An den Stirnseiten 22 der Fräswalze 12 und neben dem Fräswalzengehäuse 10 ist jeweils ein höhenverstellbarer Seitenschild 15 angeordnet, der als Kantenschutz dient.At the end faces 22 of the milling drum 12 and adjacent to the Fräswalzengehäuse 10 each a height-adjustable side plate 15 is arranged, which serves as edge protection.

The milling drum 12 rotates in the view from the right side of Fig. 2 seen in clockwise direction.

Die einzige Fräswalze 12 kann auch aus mehreren Teilen zusammengesetzt sein, oder beispielsweise aus mindestens einem auf einen Grundkörper aufgeschobenen Walzenrohr bestehen. Desgleichen kann die Fräswalze auch aus mehreren Segmenten zusammengesetzt sein.The single milling drum 12 can also be composed of several parts, or for example consist of at least one pushed onto a base roller tube. Likewise, the milling drum can also be composed of several segments.

Oberhalb der Fräswalze 12 befindet sich ein Fahrstand 16, der zwei Sitze 20 mit zwei Lenkeinrichtungen 24 aufweisen kann, die für links- bzw. rechtsbündiges Fräsen entlang einer Straße vorgesehen sind. Es versteht sich, dass auch ein quer zur Fahrtrichtung verschiebbarer Fahrstand mit einem Sitz mit zugehöriger Lenkeinrichtung 24 verwendet werden kann, der je nach Bedarf auf die linke oder rechte Seite der Großfräse 1 verschiebbar ist.Above the milling drum 12 is a control station 16, which may have two seats 20 with two steering devices 24, which are provided for left- or right-aligned milling along a road. It is understood that also a transverse to the direction of travel control station can be used with a seat with associated steering device 24, which is displaced as needed on the left or right side of the large milling machine 1.

Der Sitz 20 ist vorzugsweise derart zur seitlichen Außenwand 26,28 ausgerichtet, dass der Sitz 20 zumindest teilweise seitlich gegenüber der Außenwand 26,28 übersteht.The seat 20 is preferably oriented in such a way to the lateral outer wall 26,28 that the seat 20 at least partially laterally opposite the outer wall 26,28 protrudes.

Wird die Großfräse 1 mit einer Nullseite an ein Hindernis entlang bewegt, z.B. an einem Laternenmast, kann der Fahrstand 16 mit dem Sitz 20, der Armlehne und dem Bedienpult 25 nach innen verschoben werden, um ein möglichst bündiges Fräsen an dem Hindernis vorbei zu erlauben.When the large milling machine 1 is moved with a null side along an obstacle, e.g. On a lamppost, the control console 16 with the seat 20, the armrest and the control panel 25 can be moved inwards to allow the most flush as possible past the obstacle.

Die Außenseite 26,28 weist vor dem Fahrerstand 16 eine Aussparung 32 auf. Diese Aussparung 32 ermöglicht die Beobachtung des vorderen Laufwerks 5 und damit die Beobachtung des momentanen Lenkeinschlags.The outside 26,28 has a recess 32 in front of the driver's cab 16. This recess 32 allows the observation of the front drive 5 and thus the observation of the current steering angle.

In Fig. 1 ist das Fräswalzengehäuse 10 mit einem angehobenen Abstreiferschild 64 gezeigt, wobei auch der Seitenschild 15 angehoben ist, um die Lage der Fräswalze 12 zu zeigen. Das Fräswalzengehäuse 10 ist linear und quer zur Fahrtrichtung 31 am Maschinenrahmen 8 verschiebbar gelagert, wodurch die Nullseite wahlweise auf der einen Außenseite 26,28 oder auf der gegenüberliegenden Außenseite des Maschinenrahmens 8 festlegbar ist.In Fig. 1 the milling drum housing 10 is shown with a raised scraper blade 64, wherein the side plate 15 is raised to show the position of the milling drum 12. The milling drum housing 10 is mounted linearly and transversely to the direction of travel 31 on the machine frame 8, as a result of which the zero side can be fixed selectively on one outer side 26, 28 or on the opposite outer side of the machine frame 8.

Die Verschiebung des Fräswalzengehäuses 10 erfolgt mit Hilfe von zwei in Fahrtrichtung des Maschinenrahmens 8 beabstandeten Führungen 34,36, die als Linearführungen ausgebildet sind.The displacement of the Fräswalzengehäuses 10 takes place by means of two spaced in the direction of travel of the machine frame 8 guides 34,36, which are designed as linear guides.

Die erste der linearen Führungen 34 ist eine Rohrführung, die in den Fign. 2 bis 4 an der Oberseite des Fräswalzengehäuses 10 angeordnet sind.The first of the linear guides 34 is a pipe guide which fits into the FIGS. 2 to 4 are arranged at the top of the Fräswalzengehäuses 10.

Die zweite lineare Führung 36 ist mit Abstand ebenfalls an der Oberseite des Fräswalzengehäuses 10 angeordnet. Die lineare Führung erfolgt zwischen den ebenen Flächen 37,38, wie sie am besten aus den Fign. 2 und 3 ersichtlich sind. Die ebene Fläche 37 ist sowohl auf der Oberseite als auch auf der Unterseite eines Balkens 39 vorgesehen, der mit Flanschteilen 41 an der Unterseite des Maschinenrahmens 8 ortsfest befestigt ist. Die ebenen Flächen 37 werden von ortsfest mit dem Fräswalzengehäuse 10 verbundenen Führungsteilen 43 umfasst, die die ebenen Flächen 38 aufweisen, die in Kontakt stehen mit den ebenen Flächen 37 des Balkens 39. Der Abstand der mit den jeweiligen ebenen Flächen 37 in Kontakt stehenden ebenen Flächen 38 ist einstellbar, so dass das Spiel zwischen den ebenen Flächen 37 und 38 mit Hilfe der Führungsteile 43 eingestellt werden kann.The second linear guide 36 is also arranged at a distance at the top of the Fräswalzengehäuses 10. The linear guide takes place between the flat surfaces 37,38, as best from the FIGS. 2 and 3 can be seen. The flat surface 37 is provided both on the top and on the underside of a beam 39 which is fixedly secured with flange portions 41 on the underside of the machine frame 8. The flat surfaces 37 are comprised of guide members 43 fixedly connected to the milling drum housing 10 and having the flat surfaces 38 in contact with the flat surfaces 37 of the beam 39. The distance of the flat surfaces 38 in contact with the respective flat surfaces 37 is adjustable, so that the play between the flat surfaces 37 and 38 can be adjusted by means of the guide members 43.

Die zweite lineare Führung 36 bildet dabei ein Loslager, während die Rohrführung der ersten linearen Führung 34 das Festlager bildet.The second linear guide 36 forms a floating bearing, while the pipe guide of the first linear guide 34 forms the fixed bearing.

Die Rohrführung besteht aus einem ortsfest über Flanschteile 42 an der Unterseite des Maschinenrahmens 8 befestigten Innenrohr 33, auf dem ein ortsfest mit dem Fräswalzengehäuse 10 verbundener Hohlzylinder 35 gleiten kann.The pipe guide consists of a stationary over flange 42 on the underside of the machine frame 8 fixed inner tube 33 on which a stationary with the Fräswalzengehäuse 10 connected hollow cylinder 35 can slide.

Eine Kolbenzylindereinheit 45, die mit einem Ende an dem Maschinenrahmen 8 und an dem anderen Ende an dem Fräswalzengehäuse 10 befestigt ist, kann die gesamte Einheit des Fräswalzengehäuses 10 mit der Fräswalze 12 und den in den Fign. 2 und 3 ersichtlichen weiteren Elementen des Fräswalzengehäuses 10, einschließlich des unteren Endes 44 der Transportbandeinrichtung 18, zwischen einer zur Außenseite der Großfräse 1 linksbündigen oder rechtsbündigen Position der Fräswalze 12 verschieben.A piston-cylinder unit 45, which is fixed at one end to the machine frame 8 and at the other end to the Fräswalzengehäuse 10, the entire unit of the Fräswalzengehäuses 10 with the milling drum 12 and the in the FIGS. 2 and 3 apparent further elements of the Fräswalzengehäuses 10, including the lower end 44 of the conveyor belt device 18, between a left-aligned to the outside of the large milling machine 1 or right-aligned position of the milling drum 12 move.

Der Hub der Kolbenzylindereinheit 45 beträgt vorzugsweise zwischen ca. 500 und ca. 1000 mm. Dies bedeutet, dass das Fräswalzengehäuse 10 mit allen in den Fign. 2 und 3 ersichtlichen Komponenten, um diesen Verfahrweg quer zur Fahrtrichtung 31 verschoben werden kann. Ist beispielsweise die Stirnseite der Fräswalze 12 in einer Position auf der in Fahrtrichtung 31 linken Seite der Maschine jenseits oder in der Nähe der Außenseite 26,28, so befindet sich die Nullseite der Maschine auf der linken Seite.The stroke of the piston-cylinder unit 45 is preferably between about 500 and about 1000 mm. This means that the Fräswalzengehäuse 10 with all in the FIGS. 2 and 3 apparent components, this travel can be moved transversely to the direction of travel 31. For example, if the end face of the milling drum 12 in a position on the left side of the machine in the direction of travel 31 on the other side or in the vicinity of the outside 26,28, so is the zero side of the machine on the left side.

Der Hub der Kolbenzylindereinheit 45 ist in Relation zur Breite der Fräswalze 12 zu sehen, die bei Großfräsen ca. 1500 mm und mehr, typischerweise 2000 mm, beträgt. Die Kolbenzylindereinheit 45 kann genügend hohe Kräfte aufbringen, um das Fräswalzengehäuse 10 mit der Fräswalze 12 auch während des Fräsbetriebes zu verschieben. Hierzu können auf der Fräswalze an den jeweiligen Stirnseiten zusätzliche Werkzeuge 13 vorgesehen sein.The stroke of the piston-cylinder unit 45 can be seen in relation to the width of the milling drum 12, which in large milling machines is about 1500 mm and more, typically 2000 mm. The piston-cylinder unit 45 can apply sufficiently high forces in order to displace the milling drum housing 10 with the milling drum 12 during the milling operation. For this purpose, additional tools 13 may be provided on the milling drum at the respective end faces.

Die zwei linearen, in Fahrtrichtung des Maschinenrahmens 8 beabstandeten Führungen 34,36 haben vorzugsweise einen größtmöglichen Abstand voneinander. Sie können das Maschinengewicht auf das Fräswalzengehäuse 10 und auf die darin gelagerte Fräswalze 12 übertragen, um hohe Schnittkräfte bei großen Frästiefen zu ermöglichen.The two linear, spaced in the direction of travel of the machine frame 8 guides 34,36 preferably have a maximum distance from each other. You can transfer the weight of the machine on the Fräswalzengehäuse 10 and mounted on the milling drum 12 to allow high cutting forces at large milling depths.

Die Kombination der linearen Führungen 34,36 erlaubt ein optimales Auffangen der auftretenden Kräfte und Drehmomente.The combination of the linear guides 34,36 allows optimal capture of the forces and torques occurring.

Der Seitenschild 15 ist beidseitig an dem Fräswalzengehäuse 10 über eine Doppelanordnung von Kolbenzylindereinheiten 17 befestigt, wobei die Doppelanordnung einen besonders großen Hub der Kolbenzylindereinheiten 17 ermöglicht.The side plate 15 is fastened on both sides to the milling drum housing 10 via a double arrangement of piston-cylinder units 17, the double arrangement allowing a particularly large stroke of the piston-cylinder units 17.

Die weiteren Hydraulikleitungen 86 sind schematisch als eine einzige Leitung dargestellt. Es versteht sich, dass für den mindestens einen hydraulischen Antrieb 80 zumindest eine Zulauf und -Rücklaufleitung benötigt wird. Der Verteiler 84 ist ortsfest an dem Fräswalzengehäuse 10 befestigt, so dass die hydraulischen Leitungen 82 nicht flexibel sein müssen und lediglich die weiteren hydraulischen Leitungen 86 so verformbar sein müssen, dass der Verfahrweg der verschiebbaren Einheit, wie aus Fig. 2 ersichtlich, ausgeführt werden kann.The further hydraulic lines 86 are shown schematically as a single line. It is understood that at least one inlet and -return line is required for the at least one hydraulic drive 80. The manifold 84 is fixedly secured to the Fräswalzengehäuse 10, so that the hydraulic lines 82 need not be flexible and only the other hydraulic lines 86 must be deformable so that the travel of the sliding unit, as shown Fig. 2 can be seen, executed.

In Fign. 2 und 3 ist auf der Frontseite des Fräswalzengehäuses 10 ein Bandschuh 40 angeordnet, der zur Aufnahme des unteren Endes 44 der Transportbandeinrichtung 18 dient.In FIGS. 2 and 3 is on the front side of the Fräswalzengehäuses 10, a belt shoe 40 is arranged, which serves to receive the lower end 44 of the conveyor belt device 18.
