Definitions

  • 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.
  • 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.
  • Such a snow groomer is known from US Pat. No. 4,572,315.
  • the implement carrier is first connected to the vehicle frame about a horizontal pivot axis.
  • the vertical swivel axis is arranged approximately in the center of the device carrier.
  • a non-generic snow groomer 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.
  • a horizontal pivot axis is located at a relatively large distance at the rear end of the triangular frame.
  • connection frame 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.
  • 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.
  • the equipment carrier is mounted in the vehicle frame with its vertical pivot axis.
  • 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.
  • 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.
  • the hose lines for the hydraulic cylinders can be kept close to the vehicle frame and very short.
  • a favorable force distribution for the hydraulic cylinders results if these are articulated on the long sides of the vehicle frame.
  • the hydraulic cylinders are articulated on a linkage frame of the implement carrier with lateral arms between the vertical and the horizontal pivot axis.
  • 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.
  • 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.
  • 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.
  • the maximum stroke of the swivel cylinder can be kept relatively low. Nevertheless, a large printing area is available at the start of lifting.
  • 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.
  • the pivot cylinder is articulated on the lead frame.
  • 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 equipment rack 4 is attached for the rear attachment of snow grooming equipment.
  • a snow blower 5 is attached to the equipment carrier 4 as a slope maintenance device.
  • a trailing roller, a cross-country track device or the like can also be attached.
  • the equipment carrier 4 has a rear connection frame 6 to which the snow blower 5 is directly attached.
  • the equipment carrier 4 is designed to be pivotable about a vertical axis 7 and about a horizontal axis 8.
  • 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.
  • 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 .
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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
  • 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.
  • 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.
