Abstract

The device comprises a smoothing apparatus which is fixed on the transverse frame (1) of the ski-track vehicle. The smoothing apparatus possesses a flexible part (9) which is intended for compacting and smoothing the ski-track levelled by a cutter of the ski-track vehicle, which part is fixed between continuations (4, 5) of the transverse frame (1). <IMAGE>

Description

Die Erfindung betrifft ein Pistenbearbeitungsgerät für Pistenfahrzeuge mit einem Querrahmen der Fortsätze, zur Aufnahme einer vom Pistenfahrzeug nachziehenden Glätteinrichtung aufweist, welche einen nach giebigen Teil zur Verdichtung und Glättung der durch eine Fräse des Pistenfahrzeuges geebneten Piste besitzt.The invention relates to a slope processing device for snow groomers with a cross frame of the extensions, for receiving a smoothing device from the snow groomer, which has a flexible part for compaction and smoothing of the slope leveled by a milling machine of the snow groomer.

Durch die europ. Patentanmeldung Nr. 211.380 ist ein Pistenfahrzeug mit einer Glätteinrichtung bekanntgeworden, welche mit einem vorderen im Querschnitt dreiecksartigen Teil an den Querrahmen des Fahrzeuges angeschlossen ist, wobei der Rahmen Fortsätze aufweist, in welche der dreiecksartige Teil seitlich eingeschoben ist. Das rückwärtige Ende des dreiecksartigen Teiles setzt sich in einem nachgiebigen Teil fort, welcher bodenseitig querein wulstförmige Rippen trägt, durch welche die Piste geebnet wird. Außerdem ist die Brust- seite des dreiecksartigen Teiles als starre Verdichtungsfläche ausgebildet. Pistenfahrzeuge dieser Art haben den Nachteil, daß der dreiecksartige Teil, welcher vorwiegend aus Kunststoff besteht, nur unter Anwendung von komplizierter Formen herstellbar ist und außerdem eine mangelnde Stabilität der Glätteinrichtung zur Folge hat.Through the European Patent application No. 211.380 has become known a snow groomer with a smoothing device which is connected to the cross frame of the vehicle with a front part with a triangular cross-section, the frame having extensions into which the triangular part is inserted laterally. The rear end of the triangular part continues in a resilient part, which carries bulge-shaped ribs on the bottom, through which the slope is leveled. In addition, the chest side of the triangular part is designed as a rigid compression surface. Snow groomers of this type have the disadvantage that the triangular part, which mainly consists of plastic, can only be produced using complicated shapes and also results in a poor stability of the smoothing device.

Aufgabe der vorliegenden Erfindung ist die Beseitigung dieses Nachteiles und die Herstellung eines vom Pistenfahrzeug nachzuziehenden Pistenbearbeitungs- gerätes, welches einfach in der Herstellung ist, eine ausreichende Abstützung am Querrahmen des Fahrzeuges bietet und zur Herstellung einfache Werkzeuge benötigt.The object of the present invention is to eliminate this disadvantage and to produce a piste processing device to be traced by the snow groomer, which is simple to manufacture, offers sufficient support on the cross frame of the vehicle and requires simple tools for the manufacture.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Glätteinrichtung in Form eines plattenförmigen, an seiner Bodenseite Wulstreihen aufweisenden elastischen Teiles unmittelbar zwischen den Fortsätzen des Querrahmens des Pistenfahrzeuges z.B. durch Verschraubung verbunden ist.This object is achieved in that the smoothing device in the form of a plate-shaped, on its bottom side rows of beads having elastic parts directly between the extensions of the cross frame of the snow groomer e.g. is connected by screw.

Weitere Einzelheiten der Erfindung werden an Hand der Zeichnung näher erläutert, in welcher.

  • Fig. 1 eine Querschnitt des Querrahmens mit der daran anschließenden Glätteinrichtung und
  • Fig. 2 die Glätteinrichtung in Druntersicht darstellt.
Further details of the invention will become apparent from the drawing explains in which.
  • Fig. 1 shows a cross section of the cross frame with the adjoining smoothing device and
  • Fig. 2 shows the smoothing device from below.

In der Zeichnung ist mit 1 der Querrahmen bezeichnet, welcher im Querschnitt rechteckige Kastenform besitzt und an seinem dem Boden zugekehrten Ende in Verlängerung seiner Seitenwände 2, 3 Fortsätze 4 bzw. 5 aufweist die in zwei im Abstand voneinander liegende, parallel zueinander verlaufende Arme 6 und 7 auslaufen, zwischen denen mittels Schraube 8 eine vorzugsweise aus Kunststoff bestehende elastische Platte 9 befestigt ist, welche im unbelasteten Zustand, wie strichliert dargestellt, im wesentlichen in der Richtung der Arme 6, 7 gegen den Pistenboden 10 schräg nach unten gerichtet ist, während sie im belasteten Zustand, d.h. beim Nachziehen über die Pistenoberfläche in eine, durch volle Linien dargestellte, horizontale Lage gebogen wird. Auf der Bodenfläche der Platte 9 sind 3 Reihen 11, 12,13 von Wülsten angeordnet, die quer zur Fahrtrichtung gelegen sind. Der schräg zum Boden gerichtete Arm 7 des Rahmens 1 dient zur Verdichtung der am Boden der Piste liegenden Schneemasse. Diese Verdichtungsfläche wird durch einen Teil der Bodenfläche der Platte 9 und die in der Fahrtrichtung gelegenen Stirnseiten 14 der Wülste 11 fortgesetzt.In the drawing, 1 denotes the transverse frame, which has a rectangular box shape in cross section and has at its end facing the floor in extension of its side walls 2, 3 extensions 4 and 5, the arms 6 and 6, which are spaced apart and parallel to one another 7 leak, between which a preferably made of plastic elastic plate 9 is fastened by means of screw 8, which in the unloaded state, as shown in broken lines, is directed obliquely downwards in the direction of the arms 6, 7 against the slope bottom 10 while it is running in the loaded state, ie when pulling over the surface of the slope is bent into a horizontal position represented by solid lines. On the bottom surface of the plate 9 3 rows 11, 12, 13 of beads are arranged, which are located transversely to the direction of travel. The arm 7 of the frame 1 directed obliquely to the ground serves to compact the snow mass lying on the ground of the runway. This compression surface is continued by a part of the bottom surface of the plate 9 and the end faces 14 of the beads 11 located in the direction of travel.
