Description

Die Erfindung bezieht sich auf Fahrzeuge, insbesondere auf Bagger oder Lader, die einen Unterwagen und einen darauf drehbar angebrachten Oberwagen aufweisen. Derartige Fahrzeuge sind allgemein bekannt. Insbesondere bezieht sich die Erfindung auf eine Vorrichtung zum Verstellen des Oberwagens relativ zum Unterwagen sowie auf ein Fahrzeug, das mit einem derartigen verstellbaren Oberwagen ausgerüstet ist.The invention relates to vehicles, in particular excavators or loaders, the one Undercarriage and an upper carriage rotatably mounted thereon. Such Vehicles are well known. In particular, the invention relates to a Device for adjusting the uppercarriage relative to the undercarriage and to a vehicle, which is equipped with such an adjustable superstructure.

Aus dem Stand der Technik EP 187 944 ist eine Maschine für Erdarbeiten mit einem Fahrgestell bekannt. Auf dem Fahrgestell 10 ist eine Drehscheibe 14 mit einem zugehörigen Antriebsmittel 18 drehbar angebracht. Auf der Drehscheibe 14 ist exzentrisch zu dem Antriebsmittel 18 ein drehbarer Schlitten 20 mit dem Mechanismus für die Erdarbeiten angebracht. Der Schlitten 20 mit dem Erdarbeitsmechanismus kann sich unabhängig von dem Drehscheibenantrieb 14,18 um einen Winkelbereich von 360° drehen.From the prior art EP 187 944 is a machine for earthworks with a Chassis known. On the chassis 10 is a turntable 14 with an associated one Drive means 18 rotatably attached. On the turntable 14 is eccentric to that Drive means 18 a rotatable carriage 20 with the mechanism for earthworks appropriate. The sled 20 with the earthwork mechanism can move independently of that Turn the turntable drive 14, 18 through an angular range of 360 °.

Aus der Druckschrift US 4 693 662 ist ferner ein kompakter Bagger bekannt, bei dem der Oberwagen ebenfalls relativ zum Fahrwerk drehbar ist. Zusätzlich kann der Ausleger des Oberwagens durch eine Führung nach links und nach rechts geschwenkt werden. Diese Konstruktion soll es dem Fahrer des Wagens erleichtern, das Gerät mittels einer Zusatzbewegung zu bedienen.A compact excavator is also known from US Pat. No. 4,693,662, in which the Superstructure is also rotatable relative to the chassis. In addition, the boom of the Upper car can be swiveled left and right by a guide. This Construction should make it easier for the driver of the car to use a device Additional movement to use.

Schließlich ist aus dem Stand der Technik GB 2 092 102 ein Drehteil 15 bekannt, das auf der Plattform 11 eines Fahrwerks drehbar gelagert ist, und seinerseits einen Aufbau 17 trägt, der sich um eine zweite Drehachse drehen kann. Wenn sich der Ausleger 19 des Aufbaus 17 von der Baggerstelle 18 wegbewegt, beschreibt die Schaufel des Auslegers 19 eine Bahn X, die weniger als kreisförmig zur Seite hin vorspringt. Finally, a rotating part 15 is known from the prior art GB 2 092 102, which on the Platform 11 of a chassis is rotatably mounted, and in turn carries a structure 17 which can rotate about a second axis of rotation. If the boom 19 of the body 17 of the excavator 18 moved away, the bucket of the boom 19 describes a path X, the protrudes less than circularly to the side.

Diesem Stand der Technik ist gemeinsam, daß außer der konventionellen Drehbewegung des Oberwagens relativ zum Unterwagen eine weitere Dreh- oder Schwenkbewegung auf dem Oberwagen möglich ist. Jedoch ist die Gesamtkonstruktion, welche die zusätzliche Bewegung ermöglicht, in allen bekannten Fällen zu aufwendig. Ferner wird bei diesem Stand der Technik das Verhältnis der Kippbelastung zur rückwärtigen Ausladung des schwenkenden Oberwagens außer Acht gelassen. Außerdem leidet der Stand der Technik unter dem Problem, daß bei kompakten Baggern, deren Oberwagen mit geringer Ausladung konstruiert ist, das auf dem Oberwagen angeordnete Führerhaus sehr beengt wird und die der Wartung unterliegenden Teile schwer zugänglich sind.This prior art has in common that in addition to the conventional rotary movement of the Upper carriage relative to the undercarriage another turning or swiveling movement on the Superstructure is possible. However, the overall construction, which is the additional movement allows, in all known cases, too expensive. Furthermore, this prior art the ratio of the tipping load to the rear outreach of the swiveling superstructure disregarded. In addition, the prior art suffers from the problem that compact excavators, the superstructure of which is constructed with a small throat, on the Upper carriage arranged cab is very cramped and the ones subject to maintenance Parts are difficult to access.

Die Erfindung hat sich daher die Aufgabe gestellt, eine Vorrichtung zum Verstellen des Oberwagens, der relativ zum Unterwagen eines Fahrzeugs in bekannter Weise drehbar angeordnet ist, anzugeben, die so einfach ausgeführt ist, daß sie als Bausatz nachträglich in ein Fahrzeug, wie z.B. einen Bagger oder Lader, eingebaut werden kann.The invention has therefore set itself the task of a device for adjusting the Upper carriage that rotates relative to the undercarriage of a vehicle in a known manner is arranged to specify, which is so simple that it can be retrofitted into a Vehicle such as an excavator or loader.

Diese Aufgabe wird erfindungsgemäß durch eine Verstellvorrichtung nach dem Patentanspruch 1 gelöst. Nach dem Anspruch 2 enthält die Verstellvorrichtung eine Exzenterplatte für eine kreisförmige Verstellbewegung; nach der Alternative des Anspruchs 3 ist eine linear geführte Verstellplatte vorgesehen; im Anspruch 4 ist eine Kombination der Exzenterplatte und der Verstellplatte zur Kombination der kreisförmigen und der linearen Verstellbewegung angegeben. Ein Fahrzeug, insbesondere ein Bagger oder Lader, in den eine solche Verstellvorrichtung eingebaut ist, ist im unabhängigen Anspruch 15 angegeben. Zweckmäßige Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.This object is achieved by an adjusting device according to the Claim 1 solved. According to claim 2, the adjustment device contains one Eccentric plate for a circular adjustment movement; according to the alternative of claim 3 a linearly guided adjustment plate is provided; in claim 4 is a combination of Eccentric plate and the adjustment plate to combine the circular and the linear Adjustment movement specified. A vehicle, especially an excavator or loader, in one such adjustment device is installed is specified in independent claim 15. Appropriate developments of the invention result from the subclaims.

Bei der Erfindung wird der Unterwagen mit einer Exzenterplatte oder Verstellplatte versehen, die einerseits den Drehkranz für den Oberwagen trägt und die andererseits ein Verstellager oder eine lineare Führung aufweist. Diese Exzenterplatte mit Verstellager bzw. diese Verstellplatte mit linearer Führung kann ohne Weiteres z.B. zwischen den Unterwagen und den Oberwagen eines konventionellen Baggers oder Laders eingebaut werden. Die Exzenterplatte und die Verstellplatte können auch miteinander kombiniert werden, indem das Verstellager der Exzenterplatte auf der Verstellplatte montiert wird. In the invention, the undercarriage is provided with an eccentric plate or adjustment plate, which on the one hand carries the slewing ring for the uppercarriage and on the other hand an adjustment bearing or has a linear guide. This eccentric plate with adjustment bearing or this Adjustment plate with linear guide can easily be e.g. between the undercarriage and the uppercarriage of a conventional excavator or loader. The Eccentric plate and the adjustment plate can also be combined with each other by the Adjustment bearing of the eccentric plate is mounted on the adjustment plate.

Der verstellbare Oberwagen nach der Erfindung weist darüber hinaus den Vorteil auf, daß er den zur Verfügung stehenden Verstellspielraum entweder dafür nutzen kann, die zulässige Kipplast einstellbar zu erhöhen, oder alternativ dafür nutzen kann, die rückwärtige Ausladung des Oberwagens beim Schwenken zu verringern. Die rückwärtige Ausladung des Oberwagens wird geringer (d.h. die Arbeitsmöglichkeit unter beengten räumlichen Verhältnissen wird entsprechend verbessert), wenn der Oberwagen relativ zu seiner Basis in Richtung des Auslegers verstellt wird. Umgekehrt wird die zulässige Kipplast erhöht (d.h. der Ausleger kann eine entsprechend größere Arbeitslast aufnehmen), wenn der Oberwagen relativ zu seiner Basis in eine der Richtung des Auslegers entgegengesetzte Richtung verstellt wird.The adjustable superstructure according to the invention also has the advantage that it can use the available adjustment space either for the permissible Can increase the tipping load adjustable, or alternatively can use the rear outreach of the superstructure when swiveling. The rear outreach of the uppercarriage becomes smaller (i.e. the possibility of working in confined spaces improved accordingly) if the superstructure relative to its base in the direction of Outrigger is adjusted. Conversely, the permissible tipping load is increased (i.e. the boom can take on a correspondingly larger workload) if the superstructure is relative to its Base is moved in a direction opposite to the direction of the boom.

Diese verbesserten Arbeitsmöglichkeiten können erfindungsgemäß erzielt werden, ohne den Oberwagen übertrieben kompakt zu bauen und den Fahrer oder Bediener im Führerhaus unzumutbar einzuengen. Auch die Wartungsfreundlichkeit wird wesentlich verbessert, wenn der Oberwagen weniger kompakt als im Stand der Technik ausgelegt ist.These improved work options can be achieved according to the invention without the Superstructure is too compact to build and the driver or operator in the cab unreasonably narrow. The ease of maintenance is also significantly improved if the superstructure is designed to be less compact than in the prior art.

Wände 31 beengten Orten eingesetzt werden, für die ein Einsatz von konventionellen Baggern ausgeschlossen ist. Je nach der relativen Positionierung des Baggers 1 zu den Wänden 31 kann der Oberwagen 3 mit Hilfe der Verstellvorrichtung 10 relativ zu dem am Boden beruhenden Unterwagen 2 so verschoben werden, daß ein durch das Heckteil 8 des Oberwagens 3 beschriebener Heckschwenkkreis 32 sich nicht mit den Hindernissen bzw. mit den Wänden 31 überschneidet. Dies wird mit Hilfe der in den Figuren 1, 2, 4 oder 7 näher dargestellten Verstellvorrichtung 10 erreicht.The excavator 1 with the adjustment device 10 according to the invention can, for example, by Obstacles or walls 31 are used in confined spaces, for which a use of conventional excavators is excluded. Depending on the relative positioning of the excavator 1 to the walls 31, the superstructure 3 can be adjusted relative to by means of the adjusting device 10 the undercarriage 2, which is based on the ground, can be moved such that a through the rear part 8 of the superstructure 3 described rear swivel circle 32 not with the obstacles or intersects with the walls 31. This is explained in more detail with the aid of FIGS. 1, 2, 4 or 7 adjustment device 10 reached.

    Der Einbau der erfindungsgemäßen Verstellvorrichtung 10 in das Fahrzeug, vor allem in den Bagger 1 oder Lader gewährleistet des weiteren auch dessen vorteilhaften Einsatz auf einem schiefen Untergrund, wie dies in den Figuren 5 und 6 dargestellt ist. Der vorteilhafte Einsatz des Baggers 1 ergibt sich in beiden Fällen aus einer für den schiefen Untergrund vorteilhaften Schwerpunktverlagerung des gesamten Fahrzeugs. So führt z.B. das longitudinale Versetzen des Oberwagens 3 relativ zum Unterwagen 2, wie dies in der Figur 5 dargestellt ist, zu einer gleichmäßigeren Gewichtsverteilung zwischen dem Unterwagen 2 und dem Untergrund. Dies hat seinerseits eine erhöhte Traktion und somit eine bessere Steigfähigkeit des Fahrzeugs bzw. des Baggers 1 im steilen Gelände zur Folge. Auch ein laterales Versetzen des Oberwagens 3 relativ zum Unterwagen 2, wie dies in der Figur 6 dargestellt ist, hat den Vorteil, daß eine durch das Versetzen bewirkte Schwerpunktverlagerung des gesamten Fahrzeugs die Gefahr eines seitlichen Umkippens auf einem schiefen Gelände wesentlich vermindern kann. Die oben beschriebene Möglichkeit einer Schwerpunktverlagerung des gesamten Fahrzeugs führt auch dazu, daß das Fahrzeug mit höheren Lasten arbeiten kann, wenn der Schwerpunkt des Fahrzeugs entsprechend der Neigung des Untergrundes mit Hilfe der Verstellvorrichtung 10 vorteilhaft verschoben ist.The installation of the adjustment device 10 according to the invention in the vehicle, especially in the Excavator 1 or loader also ensures its advantageous use on one inclined underground, as shown in Figures 5 and 6. The advantageous use of the excavator 1 results in both cases from an advantageous for the inclined underground Shifting the center of gravity of the entire vehicle. For example, the longitudinal displacement of the superstructure 3 relative to the undercarriage 2, as shown in FIG. 5, to one more even weight distribution between the undercarriage 2 and the ground. This for its part has increased traction and thus better climbing ability of the vehicle or of excavator 1 in steep terrain. Lateral displacement of the superstructure 3 relative to the undercarriage 2, as shown in Figure 6, has the advantage that a due to the shifting of the center of gravity of the entire vehicle, the danger of lateral tipping on a sloping terrain can significantly reduce. The Ability to shift the center of gravity of the entire vehicle as described above also that the vehicle can work with higher loads when the center of gravity of the Vehicle according to the inclination of the ground using the adjusting device 10 is advantageously moved.
