Description

Die vorliegende Erfindung betrifft ein Pistenfahrzeug mit einem am Fahrzeugheck angelenkten Geräteträger für den Heckanbau von Pistenpflegegeräten, der einen nach hinten gerichteten Anschlußrahmen aufweist und jeweils um eine vertikale und um eine horizontale Achse schwenkbar ist.The present invention relates to a snow groomer with a device carrier articulated on the rear of the vehicle for the rear attachment of snow grooming equipment, which has a rear-facing lead frame and can be pivoted about a vertical and a horizontal axis.

Pistenfahrzeuge mit derartigen Geräteträgern dienen dazu, Pistenpflegegeräte zur Pisten- oder Loipenpflege zu schleppen. Die schwenkbare Ausgestaltung des Geräteträgers ermöglicht überhaupt erst das Kurvenfahren solcher Pistenfahrzeuge. Die horizontale Schwenkachse dieser Geräteträger dient in aller Regel dazu, das Pistenpflegegerät auszuheben und in bodenkontaktfreier Lage zu transportieren.Snow groomers with such equipment carriers are used to tow snow grooming equipment for snow grooming or cross-country skiing. The pivotable design of the implement carrier makes it possible for such snow groomers to corner in the first place. The horizontal swivel axis of this equipment rack is usually used to lift the slope grooming device and to transport it in a position that is not in contact with the ground.

Ein solches Pistenfahrzeug ist aus der US-PS 4 572 315 bekannt. Bei diesem Pistenfahrzeug ist der Geräteträger zunächst um eine horizontale Schwenkachse mit dem Fahrzeugrahmen verbunden. Die vertikale Schwenkachse ist in Längsrichtung gesehen etwa in der Mitte des Geräteträgers angeordnet. Obwohl dieses Pistenfahrzeug bereits ein Kurvenfahren ermöglicht, ohne das Pistenpflegegerät ausheben zu müssen, ist die Belastung des Geräteträgers beim Kurvenfahren relativ groß, so daß der Geräteträger entsprechend aufwendig und schwer konstruiert ist. Auch die in den Schwenkachsen vorgesehenen Gelenke sind hohen Beanspruchungen unterworfen, so daß relativ häufig Wartungsarbeiten vorzunehmen sind.Such a snow groomer is known from US Pat. No. 4,572,315. In this snow groomer, the implement carrier is first connected to the vehicle frame about a horizontal pivot axis. When viewed in the longitudinal direction, the vertical swivel axis is arranged approximately in the center of the device carrier. Although this snow groomer already enables cornering without having to lift the piste grooming device, the load on the implement carrier when cornering is relatively high, so that the implement carrier is correspondingly complex and heavy in construction. The joints provided in the swivel axes are also subjected to high loads, so that maintenance work has to be carried out relatively frequently.

Aus der US-PS 3 867 992 ist ein gattungsfremdes Pistenfahrzeug bekannt, bei dem ein Geräteträger ungefähr in der Fahrzeugmitte an einer vertikalen Achse angelenkt ist. Der Geräteträger verfügt über einen in der Draufsicht dreieckförmigen Rahmen, der über die Ladefläche geführt ist und auf derselben lagernd aufgesattelt ist.From US-PS 3 867 992 a non-generic snow groomer is known, in which an equipment carrier is articulated approximately in the middle of the vehicle on a vertical axis. The equipment carrier has a triangular frame in plan view, which is guided over the loading area and is saddled on it.

Eine horizontale Schwenkachse befindet sich mit relativ großem Abstand am heckseitigen Ende des dreieckförmigen Rahmens.A horizontal pivot axis is located at a relatively large distance at the rear end of the triangular frame.

Bedingt durch die geschilderte Lagerung weichen die am Anschlußrahmen angeordneten Pistenpflegegeräte bei Kurvenlauf stark zur Kurveninnenseite hin ab, wodurch erhöhte Vorsicht geboten ist. Der Anschlußrahmen muß stark ausgebildet sein, da er sich über die gesamte Fahrzeugbreite erstreckt und bedingt durch die Lagerung große Momente aufzunehmen sind. Ein schneller Wechsel des gattungsfremden Geräteträgers ist nicht vorgesehen und auch nicht möglich.Due to the described storage, the piste grooming devices arranged on the connection frame deviate strongly towards the inside of the curve when cornering, which means that increased caution is required. The lead frame must be strong, since it extends over the entire width of the vehicle and large moments must be absorbed due to the storage. A quick change of the non-generic device carrier is not provided and also not possible.

Es ist daher Aufgabe der vorliegenden Erfindung, ein Pistenfahrzeug der eingangs genannten Art dahingehend zu verbessern, daß der Geräteträger leichter ausgebildet werden kann, wobei dennoch der Wartungsaufwand verringert werden kann.It is therefore an object of the present invention to improve a snow groomer of the type mentioned at the outset in such a way that the equipment carrier can be made lighter, but the maintenance effort can nevertheless be reduced.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die horizontale Schwenkachse zwischen der vertikalen Schwenkachse und dem Anschlußrahmen angeordnet ist und die vertikale Schwenkachse den Geräteträger mit dem Heck des Fahrzeugs verbindet.This object is achieved in that the horizontal pivot axis is arranged between the vertical pivot axis and the lead frame and the vertical pivot axis connects the equipment carrier to the rear of the vehicle.

Hierdurch ergibt sich zwangsläufig, daß die vertikale Schwenkachse nahe der Hochachse des Pistenfahrzeuges angeordnet ist, um die das Pistenfahrzeug seine Lenkbewegungen ausführt. Die auf den Geräteträger wirkenden Kräfte sind daher wesentlich geringer, so daß der Geräteträger selbst auch wesentlich leichter ausgebildet werden kann. Da die horizontale Schwenkachse zwischen vertikaler Schwenkachse und Anschlußrahmen angebracht ist, ist die Belastung der Schwenkgelenke in der horizontalen Schwenkachse bei Kurvenfahrten des Pistenfahrzeuges beträchtlich vermindert. Beide Schwenkachsen befinden sich relativ nahe an dem Fahrzeugrahmen, so daß der Geräteträger bereits aus diesem Grunde ohne konstruktive Maßnahmen eine für die Fahrsicherheit förderliche erhöhte Steifigkeit aufweist. Der sich von den Schwenkachsen heckwärtig erstreckende Teil des Geräteträgers ist praktisch keinerlei Momentenbelastung unterworfen.This inevitably results in the vertical pivot axis being arranged near the vertical axis of the snow groomer, around which the snow groomer performs its steering movements. The forces acting on the equipment carrier are therefore significantly lower, so that the equipment carrier itself can also be made much lighter. Since the horizontal swivel axis is attached between the vertical swivel axis and the connecting frame, the load on the swivel joints in the horizontal swivel axis is considerably reduced when the snow groomer is cornering. Both swivel axes are located relatively close to the vehicle frame, so that for this reason the implement carrier already has increased rigidity, which is conducive to driving safety, without constructive measures. The part of the equipment carrier which extends rearward from the swivel axes is subjected to practically no moment load.

Besonders vorteilhaft ist es, wenn der Geräteträger mit seiner vertikalen Schwenkachse im Fahrzeugrahmen gelagert ist. Hierdurch besteht der Geräteträger praktisch nur aus einem einer Momentenbelastung nicht unterworfenen Teil, während eine eventuelle Momentenbelastung von dem wesentlich steiferen Fahrzeugrahmen aufgenommen wird. Durch diese Anordung direkt am Fahrzeugrahmen befindet sich der Geräteträger größtenteils zwischen den beiden Laufketten des Pistenfahrzeuges. Hierdurch rückt der Schwerpunkt der Gesamteinheit Pistenfahrzeug mit Pistenpflegegerät weiter nach vorne, was die Fahrsicherheit dieser Einheit günstig beeinflußt.It is particularly advantageous if the equipment carrier is mounted in the vehicle frame with its vertical pivot axis. As a result, the equipment carrier practically consists only of a part not subjected to a moment load, while a possible moment load is absorbed by the much stiffer vehicle frame. Due to this arrangement directly on the vehicle frame, the implement carrier is largely between the two tracks of the snow groomer. As a result, the focus of the entire unit snow groomer with snow grooming device moves forward, which has a favorable effect on the driving safety of this unit.

Ein noch einfacheres Lenken des Pistenfahrzeuges und damit verbunden eine noch geringere Momentenbelastung des Fahrzeugrahmens ergibt sich, wenn die vertikale Schwenkachse des Geräteträgers nahe der Hochachse des Pistenfahrzeuges angeordnet ist.An even easier steering of the snow groomer and, associated therewith, an even lower moment load on the vehicle frame results when the vertical pivot axis of the equipment carrier is arranged near the vertical axis of the snow groomer.

Bei Pistenfahrzeugen, bei denen der Geräteträger mittels Hydraulikzylindern um die Schwenkachse bewegbar ist, ist es vorteilhaft, daß für die Bewegung des Geräteträgers um die vertikale Schwenkachse mit Abstand seitlich neben der Schwenkachse mindestens ein Hydraulikzylinder angeordnet ist, der einerseits an dem Geräteträger und andererseits an dem Fahrzeugrahmen angelenkt ist. Hierdurch können die Schlauchleitungen für die Hydraulikzylinder nahe am Fahrzeugrahmen und sehr kurz gehalten werden.In snow groomers, in which the implement carrier can be moved about the pivot axis by means of hydraulic cylinders, it is advantageous that at least one hydraulic cylinder is arranged for the movement of the implement carrier about the vertical pivot axis at a distance laterally next to the pivot axis, which on the one hand on the implement carrier and on the other hand on the Vehicle frame is articulated. As a result, the hose lines for the hydraulic cylinders can be kept close to the vehicle frame and very short.

Eine günstige Kraftverteilung für die Hydraulikzylinder ergibt sich, wenn diese an den Längsseiten des Fahrzeugrahmens angelenkt sind.A favorable force distribution for the hydraulic cylinders results if these are articulated on the long sides of the vehicle frame.

Bevorzugt ist, daß die Hydraulikzylinder an einem Anlenkrahmen des Geräteträgers mit seitlichen Auslegern zwischen der vertikalen und der horizontalen Schwenkachse angelenkt sind. Hierdurch sind die seitlichen Hydraulikzylinder praktisch parallel nebeneinander angeordnet, wobei sie diesen Zustand nahezu in jeder Schwenkbewegung des Geräterahmens beibehalten, was einen günstigen Kraftangriff gewährleistet und somit die Verwendung relativ kleiner Hydraulikzylinder gestattet.It is preferred that the hydraulic cylinders are articulated on a linkage frame of the implement carrier with lateral arms between the vertical and the horizontal pivot axis. As a result, the lateral hydraulic cylinders are arranged practically parallel next to one another, whereby they maintain this state in almost every pivoting movement of the device frame, which ensures a favorable force application and thus permits the use of relatively small hydraulic cylinders.

Von besonderem Vorteil ist es, daß der Geräteträger im Bereich zwischen der horizontalen Schwenkachse und dem Anschlußrahmen als Kastenprofil ausgebildet ist. Diese äußerst leichte Bauweise ist möglich, da dieser Bereich des Geräteträgers bei Kurvenfahrten des Pistenfahrzeuges praktisch nicht unter einer Momentenbelastung steht. Bevorzugt wird insbesondere auch, daß die sich gegenüberliegenden Kanten des Kastenprofiles jeweils in einer im wesentlichen horizontalen oder vertikalen Ebene angeordnet sind.It is particularly advantageous that the equipment carrier in the area between the horizontal Swivel axis and the lead frame is designed as a box profile. This extremely light construction is possible because this area of the implement carrier is practically not subject to a moment load when cornering the snow groomer. It is particularly preferred that the opposite edges of the box section are each arranged in a substantially horizontal or vertical plane.

Gemäß einer Weiterbildung der vorliegenden Erfindung ist unterhalb des Kastenprofiles ein Schwenkzylinder für die Schwenkbewegung um die horizontale Achse angeordnet, der einerseits mit dem Kastenprofil und andererseits mit dem Anlenkrahmen des Geräteträgers verbunden ist. Dieser Schwenkzylinder dient zum Ausheben des Pistenpflegegerätes. Hierdurch kann der maximale Hub des Schwenkzylinders relativ gering gehalten werden. Dennoch steht zu Beginn des Anhebens eine hohe Druckfläche zur Verfügung. Darüber hinaus liegt der Schwenkzylinder im Schutz des Kastenprofiles, so daß der Schnee von den dachförmigen Schrägen des Kastenprofiles an dem Schwenkzylinder vorbei herabrutscht, ohne daß dies zu einer Schneeansammlung auf dem Schwenkzylinder führen würde. Das ist insbesondere deswegen wichtig, da dieser Schwenkzylinder nicht sehr häufig gebraucht wird und sich dadurch auch nicht durch eigene Tätigkeit von Schnee befreien kann.According to a development of the present invention, a pivot cylinder for the pivoting movement about the horizontal axis is arranged below the box profile, which is connected on the one hand to the box profile and on the other hand to the articulation frame of the equipment carrier. This swivel cylinder is used to lift the slope grooming device. As a result, the maximum stroke of the swivel cylinder can be kept relatively low. Nevertheless, a large printing area is available at the start of lifting. In addition, the swivel cylinder is in the protection of the box profile, so that the snow slides down from the roof-shaped slopes of the box profile past the swivel cylinder without this leading to snow accumulation on the swivel cylinder. This is particularly important because this swivel cylinder is not used very often and therefore cannot free itself from snow due to its own activity.

Gemäß einer bevorzugten Ausgestaltung ist der Schwenkzylinder an dem Anschlußrahmen angelenkt.According to a preferred embodiment, the pivot cylinder is articulated on the lead frame.

Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand einer Zeichnung näher erläutert. Es zeigen:

  • Figur 1 den Heckbereich eines erfindungsgemäßen Pistenfahrzeuges in einer Seitenansicht,
  • Figur 2 den Heckbereich des Pistenfahrzeuges in einer Draufsicht.
An exemplary embodiment of the invention is explained in more detail below with reference to a drawing. Show it:
  • FIG. 1 shows the rear area of a snow groomer according to the invention in a side view,
  • Figure 2 shows the rear area of the snow groomer in a plan view.

In der Zeichnung ist der Heckbereich eines erfindungsgemäßen Pistenfahrzeuges 1 dargestellt. Deutlich zu erkennen ist der Fahrzeugrahmen 2, der zwischen zwei Laufketten 3 des Pistenfahrzeuges angeordnet ist.The drawing shows the rear area of a snow groomer 1 according to the invention. The vehicle frame 2, which is arranged between two crawlers 3 of the snow groomer, can be clearly seen.

An dem Fahrzeugrahmen 2 des Pistenfahrzeuges 1 ist ein Geräteträger 4 für den Heckanbau von Pistenpflegegeräten angebracht. Bei dem hier dargestellten Ausführungsbeispiel ist als Pistenpflegegerät eine Schneefräse 5 an dem Geräteträger 4 befestigt. Anstelle der Schneefräse 5 kann jedoch auch eine Nachlaufwalze, ein Loipenspurgerät oder dergleichen angebracht sein.On the vehicle frame 2 of the snow groomer 1, an equipment rack 4 is attached for the rear attachment of snow grooming equipment. In the exemplary embodiment shown here, a snow blower 5 is attached to the equipment carrier 4 as a slope maintenance device. Instead of the snow blower 5, however, a trailing roller, a cross-country track device or the like can also be attached.

Der Geräteträger 4 weist einen heckwärtigen Anschlußrahmen 6 auf, an dem die Schneefräse 5 unmittelbar befestigt ist.The equipment carrier 4 has a rear connection frame 6 to which the snow blower 5 is directly attached.

Der Geräteträger 4 ist um eine vertikale Achse 7 und um eine horizontale Achse 8 schwenkbar ausgebildet.The equipment carrier 4 is designed to be pivotable about a vertical axis 7 and about a horizontal axis 8.

Die vertikale Schwenkachse 7 ist in unmittelbarer Nähe des Fahrzeugrahmens 2 angeordnet, während die horizontale Achse 8 mit größerem Abstand von dem Fahrzeugrahmen 2 zwischen der vertikalen Achse 7 und dem Anschlußrahmen 6 angeordnet ist.The vertical pivot axis 7 is arranged in the immediate vicinity of the vehicle frame 2, while the horizontal axis 8 is arranged at a greater distance from the vehicle frame 2 between the vertical axis 7 and the lead frame 6.

Wie besonders gut aus der Draufsicht in Figur 2 ersichtlich ist, ist der Geräteträger 4 mit seiner vertikalen Schwenkachse 7 im Fahrzeugrahmen 2 gelagert, d. h. die Halterung für die vertikale Schwenkachse 7 ist Bestandteil des Fahrzeugrahmens 2. Die vertikale Schwenkachse 7 ist somit Verbindungsglied zwischen Fahrzeugrahmen 2 und Geräteträger 4. Die horizontale Schwenkachse 8 ist in geringem Abstand hinter der vertikalen Achse 7 und zwar im oberen Bereich der vertikalen Schwenkachse 7 angeordnet.As can be seen particularly well from the top view in FIG. 2, the device carrier 4 is mounted with its vertical pivot axis 7 in the vehicle frame 2, i. H. the holder for the vertical swivel axis 7 is part of the vehicle frame 2. The vertical swivel axis 7 is thus a link between the vehicle frame 2 and equipment carrier 4. The horizontal swivel axis 8 is arranged at a short distance behind the vertical axis 7 and in the upper region of the vertical swivel axis 7 .

Die vertikale Achse 7 selbst ist aufgrund ihrer unmittelbaren Anordnung an dem Fahrzeugrahmen 2 nahe der Hochachse des Pistenfahrzeuges 1 angeordnet, d. h. nahe der Achse, um die sich das Pistenfahrzeug 1 beim Wenden dreht.The vertical axis 7 itself is arranged due to its direct arrangement on the vehicle frame 2 near the vertical axis of the snow groomer 1, i. H. near the axis about which the snow groomer 1 turns when turning.

Zur Bewegung des Geräteträgers 4 um seine beiden Schwenkachsen 7 und 8 sind Hydraulikzylinder 9 und 10, bzw. ein Schwenkzylinder, der ebenfalls als Hydraulikzylinder ausgebildet ist, vorgesehen.Hydraulic cylinders 9 and 10, or a pivot cylinder, which is also designed as a hydraulic cylinder, are provided for moving the device carrier 4 about its two pivot axes 7 and 8.

Die beiden Hydraulikzylinder 9 und 10 sind in Fahrtrichtung gesehen beidseitig der vertikalen Schwenkachse 7 angeordnet. Mit jeweils einem Ende sind die Hydraulikzylinder 9 und 10 an dem Fahrzeugrahmen 2 angelenkt, während sie mit dem jeweils gegenüberliegendem Ende an dem Geräteträger 4 angeordnet sind.The two hydraulic cylinders 9 and 10 are arranged on both sides of the vertical pivot axis 7 when viewed in the direction of travel. The hydraulic cylinders 9 and 10 are articulated to the vehicle frame 2 at one end, while they are arranged at the opposite end on the implement carrier 4.

Genauer gesagt sind die Hydraulikzylinder einerseits an den Längsseiten 12 und 13 des Fahrzeugrahmens 2 und andererseits an seitlichen Auslegern 14 und 15 eines Anlenkrahmens 16 des Geräteträgers 4 angelenkt. Die seitlichen Ausleger 14 und 15 stehen etwa quer zur Fahrtrichtung jochartig von dem Anlenkrahmen 16 ab. Die beiden Hydraulikzylinder 9 und 10 stehen daher in einer nahezu parallelen Anordnung zueinander, Da die seitlichen Ausleger 14 und 15 leicht in Fahrtrichtung weisen, behält der ausschiebende Hydraulikzylinder 9 bzw. 10 während der Ausschubbewegung im wesentlichen seine Orientierung bei.More precisely, the hydraulic cylinders are articulated on the one hand on the longitudinal sides 12 and 13 of the vehicle frame 2 and on the other hand on the lateral arms 14 and 15 of a link frame 16 of the implement carrier 4. The lateral arms 14 and 15 protrude yoke-like from the articulation frame 16 approximately transversely to the direction of travel. The two hydraulic cylinders 9 and 10 are therefore in an almost parallel arrangement to one another. Since the lateral arms 14 and 15 point slightly in the direction of travel, the extending hydraulic cylinder 9 and 10 essentially maintains their orientation during the extension movement.

Wie deutlich aus der Zeichnung hervorgeht, ist der Geräteträger 4 im Bereich zwischen der horizontalen Schwenkachse 8 und dem Anschlußrahmen 6 als Kastenprofil 17 ausgebildet. Das Kastenprofil 17 weist einen quadratischen Querschnitt auf. Die Anordnung des Kastenprofiles 17 ist jedoch so, daß die sich jeweils gegenüberliegenden Kanten 18 bzw. 19 jeweils in einer im wesentlichen vertikalen Ebene bzw. in einer horizontalen Ebene angeordnet sind. Das bedeutet, daß das Kastenprofil 17 nicht mit einer Seitenfläche, sondern mit einer Kante nach unten weist.As can be clearly seen from the drawing, the device carrier 4 is formed in the area between the horizontal pivot axis 8 and the lead frame 6 as a box profile 17. The box section 17 has a square cross section. However, the arrangement of the box section 17 is such that the respective opposite edges 18 and 19 are each arranged in a substantially vertical plane or in a horizontal plane. This means that the box section 17 does not point with a side surface but with an edge downwards.

Der Schwenkzylinder 11 für die Schwenkbewegung des Geräteträgers 4 um seine horizontale Achse 8 ist unterhalb des Kastenprofiles 17 angeordnet. Der Schwenkzylinder 11 ist mit seinem einen Ende 20 an dem Anlenkrahmen 16 angelenkt und zwar mit vertikalem und horizontalem Abstand zur Schwenkachse 8. Das hintere Ende 21 des Schwenkzylinders 11 ist an dem Anschlußrahmen 6 mit vertikalem Abstand zur Längsachse des Kastenprofiles 17 angelenkt. Da der Anschlußrahmen 6 fest mit dem Kastenprofil 17 verbunden ist, verbindet der Schwenkzylinder 11 praktisch das Kastenprofil 17 mit dem Anlenkrahmen 16.The pivot cylinder 11 for the pivoting movement of the device carrier 4 about its horizontal axis 8 is arranged below the box section 17. The swivel cylinder 11 is articulated at its one end 20 to the articulation frame 16 with a vertical and horizontal distance from the swivel axis 8. The rear end 21 of the swivel cylinder 11 is articulated on the connection frame 6 with a vertical distance from the longitudinal axis of the box section 17. Since the lead frame 6 is firmly connected to the box section 17, verbin det the pivot cylinder 11 practically the box section 17 with the articulation frame 16th

Im folgenden wird die Wirkungsweise des erfindungsgemäßen Pistenfahrzeuges anhand der in bestimmten Fahrsituationen auftretenden Schwenkbewegungen des Geräteträgers erläutert.The mode of operation of the snow groomer according to the invention is explained below on the basis of the pivoting movements of the implement carrier that occur in certain driving situations.

Ausgegangen wird von dem in Figur 1 dargestellten Zustand, d. h., daß an dem Anschlußrahmen 6 des Geräteträgers 4 ein Pistenpflegegerät 5 angebracht ist. Beim Wenden des Pistenfahrzeuges 1 kann mittels der Hydraulikzylinder 9 und 10 eine Schwenkbewegung des Geräteträgers 4 um seine vertikale Achse 7 bewirkt werden. Dadurch knickt die Längsachse des Geräteträgers 4 bezogen auf die Längsachse des Pistenfahrzeuges 1 ein. Dies ist in Figur 2 durch die Darstellung des Geräteträgers 4 mit strichpunktierten Linien dargestellt. Bei dem hier beschriebenen Ausführungsbeispiel beträgt der Knickeinschlag sowohl zur rechten als auch zur linken Fahrzeugseite jeweils 20 Grad.It is assumed that the state shown in Figure 1, ie. that is, a piste grooming device 5 is attached to the lead frame 6 of the equipment carrier 4. When turning the snow groomer 1, a pivoting movement of the implement carrier 4 about its vertical axis 7 can be effected by means of the hydraulic cylinders 9 and 10. As a result, the longitudinal axis of the equipment carrier 4 bends in relation to the longitudinal axis of the snow groomer 1. This is shown in Figure 2 by the representation of the device carrier 4 with dash-dotted lines. In the exemplary embodiment described here, the buckling is 20 degrees in each case on the right and on the left side of the vehicle.

Da die vertikale Achse 7 unmittelbar am Fahrzeugrahmen 2 und damit nahe der Hochachse des Pistenfahrzeuges 1 angeordnet ist, sind die auf den Geräteträger 4 wirkenden seitlichen Momente äußerst gering. Die Schwenkgelenke in den Schwenkachsen 7 und 8 sowie in den Anschlußstellen der Hydraulikzylinder 9, 10 und 11 werden daher nur sehr gering beansprucht.Since the vertical axis 7 is arranged directly on the vehicle frame 2 and thus close to the vertical axis of the snow groomer 1, the lateral moments acting on the implement carrier 4 are extremely low. The swivel joints in the swivel axes 7 and 8 and in the connection points of the hydraulic cylinders 9, 10 and 11 are therefore only subjected to very little stress.

Ist das Wendemanöver beendet, wird der Geräteträger 4 mit Hilfe der Hydraulikzylinder 9 und 10 wieder in seine gerade Position gebracht, wie sie in Figur 2 in ausgezogener Linie dargestellt ist.When the turning maneuver has ended, the implement carrier 4 is brought back into its straight position by means of the hydraulic cylinders 9 and 10, as is shown in solid lines in FIG.

Soll nun das Pistenpflegegerät 5 ausgehoben werden, so wird der Schwenkzylinder 11 ausgefahren. Dadurch schwenkt das Kastenprofil 17 um die horizontale Schwenkachse 8 nach oben, bis sich der Geräterahmen 4 in der in Figur 1 in strichpunktierten Linien dargestellten Position befindet.If the slope grooming device 5 is now to be lifted, the pivot cylinder 11 is extended. As a result, the box section 17 pivots upward about the horizontal pivot axis 8 until the device frame 4 is in the position shown in broken lines in FIG.

Wie aus der Darstellung in Figur 1 deutlich ersichtlich ist, liegt der Schwerpunkt der Anordnung aus Geräteträger 4 und Schneefräse 5 sehr nahe am Pistenfahrzeug 1. Dadurch wird die Hecklastigkeit des Pistenfahrzeuges 1 in Grenzen gehalten, so daß das Fahrverhalten des Pistenfahrzeuges mit ausgehobenen Pistenpflegegerät kaum beeinträchtigt wird. Das Herunterschwenken des Pistenpflegegerätes und des Geräteträgers 4 geschieht dadurch, daß der Schwenkzylinder 11 eingefahren wird.As can be clearly seen from the illustration in FIG. 1, the focus of the arrangement of equipment carrier 4 and snow blower 5 is very close to the snow groomer 1. This keeps the rear load of the snow groomer 1 within limits, so that the driving behavior of the snow groomer with lifted snow grooming device is hardly impaired becomes. The piste grooming device and the equipment carrier 4 are swiveled down by retracting the swivel cylinder 11.

Durch noch weiteres Einfahren des Schwenkzylinders 11 ist es möglich, mit Hilfe des Geräteträgers 4 eine Tiefenanpassung des Pflegegerätes entsprechend der Schneeverhältnisse vorzunehmen.By retracting the swivel cylinder 11 even further, it is possible to use the device carrier 4 to adjust the depth of the maintenance device in accordance with the snow conditions.

Der Geräteträger 4 des erfindungsgemäßen Pistenfahrzeuges 1 ist sehr einfach und mit nur wenigen Teilen aufgebaut, die zudem nur geringes Gewicht aufweisen. Dennoch ist der Geräteträger in sich steif. Aufgrund der günstigen Anordnung der vertikalen und horizontalen Achsen wird die Gelenkbeanspruchung gering gehalten.The equipment carrier 4 of the snow groomer 1 according to the invention is very simple and constructed with only a few parts, which also have a low weight. Nevertheless, the equipment carrier is stiff in itself. Due to the favorable arrangement of the vertical and horizontal axes, the joint stress is kept low.
