Definitions

  • the above invention relates to a device for generating a cross-country ski run according to the preamble of claim 1.
  • Sledge-like devices for producing a cross-country ski run are known to represent an additional device which can be attached to the snow vehicle and which is usually arranged after a device for processing and smoothing the snow field.
  • runners for producing the track are arranged on the underside of the device, these runners are arranged parallel to the direction of pull of the snow vehicle and produce parallel tracks which are arranged at the same mutual distance over the entire length of the cross-country ski run.
  • the object of the above invention is to create a device for producing a cross-country track in which the driver of the snow vehicle is able to quickly change the distance between the tracks during the production of the cross-country ski track.
  • a simple shifting device of the runners for forming the cross-country ski track with a small space requirement for the drive devices and simple means for supplying energy from the snow vehicle is achieved in that the controllable drive devices of the runners consist of a hydraulic piston-cylinder unit.
  • a piston-cylinder unit with opposing piston rods is provided on the slide between two cross-country runners, and each of these piston rods is connected to a portal-like holder for the cross-country runners.
  • Rapid control by the driver of the snow vehicle for changing the mutual distance between the cross-country runners is made possible by the fact that the actuating devices for the drive devices of the runners are provided in the driver's cabin.
  • the main advantage that can be achieved with the track device according to the invention is that the distance between the track tracks at the start of the track is set automatically in accordance with the guidelines of the competition organizer, or while the snow vehicle is traveling on tracks that are not used for competition purposes , is adjustable without allowing the driver of the snow vehicle the necessary attention to operate and steer the vehicle and without undesired dead times.
  • the set-up times for the production of the cross-country ski run are not extended, since it is no longer necessary to stop the snow vehicle for it. For this reason, the driver of the snow vehicle can trace the trail for every need (for example on sloping terrain or at difficult cross-country ski trail) without wasting valuable time and without having to leave the driver's cabin of the snow vehicle.
  • the cross-country runners can be adjusted in a simple manner by operating switches or similar devices which are arranged in an easily accessible position in the driver's cab.
  • the slide 1 for producing the cross-country ski trail has a plate 2 with two runners 3 for creating the track.
  • the runners 3 for producing the track are arranged so as to be controllably displaceable transversely to the direction of movement F of the slide.
  • guide slots 5 which are arranged transversely to the feed direction of the slide and are shown in Fig. 1, are incorporated.
  • a portal-like holder 6 is attached, which consists of two columns 7 and a yoke 8.
  • the piston rod 10 is attached to a piston-cylinder unit 11 which is arranged on the slide plate 2.
  • the piston-cylinder units 11 are advantageously designed as hydraulic groups and are acted upon by a pump, which is driven by the engine of the snow vehicle, via flexible lines with pressure medium.
  • the actuating means for the piston-cylinder units 11 are advantageously provided in the cab.
  • the piston-cylinder units 11 can work with a constant stroke. If this stroke is smaller than the length of the slots 5, it is advantageously possible to dispense with the provision of limit switches, components which would only increase the construction effort.
  • the piston-cylinder units 11 can also be designed so that different stroke movements can be carried out, i.e. the stroke movements can have different values. It is therefore possible to provide a larger number of different distances between the tracks on the trail.
  • tracks 12, 13 arranged parallel to one another can be produced at a distance (a). If the piston rod 10 is retracted, i.e. If the corresponding runner 3 is moved outwards, a track with increasing distance, i.e. creates a track with the distance (b).
  • piston-cylinder units 11 By using piston-cylinder units 11 with a differentiated stroke, a much larger number of mutual spacers (a, b, c) can be found between the tracks be generated.
  • piston-cylinder units 11 by technically equivalent devices e.g. to replace electric motors or lever devices.
  • a piston-cylinder unit with two differentially operable piston rods which is arranged on the plate 2 between the runners 3, can be provided.
  • each piston rod is connected to a yoke of the associated runners, which are shown in broken lines in FIG. 2.
  • the design of the yoke 6 can also differ from the design shown, e.g. a one-piece device can be provided.
