Definitions

  • the invention relates to a track device with at least one track plate on which at least one track body is mounted, as well as at least one track milling machine, which is integrated in the track plate, and a piste grooming vehicle with a rear attachment, are arranged on the at least two spaced next to each other track devices.
  • Such a track device has two track bodies, which are arranged on an underside of a track plate and designed in the manner of a wedge shoe.
  • Such a track device is usually pulled by a tracked vehicle used for snow grooming.
  • a snow blower is connected upstream, either by one at the rear of the piste grooming vehicle attached rear tiller or by the track device associated with the track bodies and upstream track milling is formed.
  • the advantage of a track cutter assigned to the track device is that only in the track area the snow can be milled deeper in order to be able to pull a high-quality track through the track bodies.
  • the snow remains firmer, which in particular an improved pole insert for a cross-country skier is possible.
  • the Tiller itself allows for deeper milling than the standard rear tiller of the piste grooming vehicle extends across the full width of the grooming vehicle.
  • the object of the invention is to provide a cross-country track device and a piste care vehicle of the type mentioned, which allow improved trail tracking.
  • the track cutter is arranged relative to the track plate adjustable.
  • the track cutter is mounted in particular liftable relative to the track plate, and / or the track cutter is adjustable transversely to the track direction relative to the track plate. If the track cutter from the track plate is mounted liftable, it is possible to convert the track cutter as required in their milling functional position or in their excavated rest position. This gives an energy saving potential. Because with relatively loose snow, the trail can be traced alone through the track body, without the track cutter makes a loosening of the snow soil in front of the track bodies.
  • the tiller With firmer snow and / or ice, the tiller is lowered and transferred to its mowing operational position, whereby the desired loosening of the snow for the subsequent traversing of the track body is achieved.
  • the burr is both in excavated rest position as well as in their milling functional position permanently in rotation, ie the milling drive remains switched on during the track operation of the track device.
  • the track milling machine can be mounted pivotably on the track plate for lifting and lowering.
  • the track milling machine by means of a linear and / or cam guide liftable and lowerable relative to the track plate.
  • the track cutter In its excavated rest position, the track cutter is with its circumference at least at the level of the underside of the track plate, so that it is ensured that the track cutter does not engage in the rest position in the snow.
  • a lifting device is provided in order to lift the track milling machine relative to the track plate.
  • the lifting device may comprise the described pivot bearing or the described linear and / or cam guide.
  • the lifting device is associated with a drive.
  • the drive is preferably carried out electrically in order to keep the installation effort and installation space for the installation of appropriate energy supply lines from the piste maintenance vehicle low. But it is also possible to make the drive pneumatically or hydraulically. With electric drive a spindle drive is provided, which allows a linear adjustment and is provided with an electric motor.
  • a plurality of track bodies are provided, wherein one track milling machine is provided per track body, which are integrated in a common track milling unit, and a traverse device is provided to adjust the track milling machine relative to the other track milling machine transversely to a track direction.
  • the design creates a further energy saving potential. Because of the design each track body is assigned its own track milling, which mills only approximately the track width, which is needed for the track drawn by the track body. Since the track width is variable by adjusting the two track body relative to each other, the track milling cutter associated with each adjustable track body is tracked in a simple manner.
  • the transverse device is associated with a drive, which is preferably carried out electrically.
  • a drive which is preferably carried out electrically.
  • this actuator hydraulically or pneumatically.
  • electrical power supply lines can be mounted and stored space-saving than hydraulic or pneumatic lines.
  • the object underlying the invention is achieved in that at least one cross-country track device is arranged transversely to a direction of travel of the piste grooming vehicle adjustable. This makes it possible to change the distance of the tracks of the adjacent trailers to each other in two or more trailers.
  • a transverse guide arrangement and an actuator are provided, which are attached to the rear attachment and act on the track device.
  • the transverse guide arrangement preferably has a cross member profile, which on the rear attachment is transversely mounted and is mounted transversely displaceable on the at least one support arm of the track device.
  • the at least one support arm of the track device is provided with a sliding shoe or the like, which is held linearly displaceable on the support profile.
  • the actuator is designed electrically, hydraulically or pneumatically and allows continuous adjustment of the cross-country track device relative to the rear attachment.
  • the actuator is also designed so that the track device is secured in position in the respective position.
  • the actuator can be designed in particular as a threaded spindle drive, wherein the support arm forms the corresponding threaded nut which is held on the threaded spindle self-locking.
  • a corresponding actuating cylinder on the support arm engage in the transverse direction and thus cause the displacement of the support arm and thus of the Loipenspur convinceds.
  • the track device is pivotally supported on the support arm to be able to be swung up for the non-functional position, for example, for transport. In the raised position of the track device it is ensured that the track milling unit does not rotate. For this purpose, a corresponding sensor is provided, which shuts off the drive of the track milling unit as soon as the track device is swung up over a defined angle. As a result, the risk of injury is excluded by rotating track milling.
  • a piste grooming vehicle 1 in the form of a tracked vehicle is provided with a rear attachment in the form of a rear tiller 2, which extends over the entire vehicle width in basically known manner.
  • the rear tiller is followed by a flexible smoothing blade, which smoothes the milled snow ground.

  • the track milling unit 8 including the carrier hood 19 is between a milling functional position and a raised resting position on the track plate 7 held pivotally.
  • the two end positions of the pivoting track milling machine 8 can be seen in Fig. 2.
  • the track milling unit 8 In the raised position of rest, the track milling unit 8 is pivoted so far upwards that it no longer touches the snow surface with its circumference. In the milling functional position (lower position in FIG. 2), the track milling unit 8 protrudes downwards through the recess of the track plate 7.
  • a hydraulically acting actuating cylinder 10 is provided, which engages the bearing flange 12 (FIG. 2) of the support arm 5 and is pivotably held on the support flange 4.
  • a lifting device 13 is provided, which is designed as an actuating cylinder acting on the carrier hood 19.
  • the actuating cylinder of the lifting device 13 is provided with an electric spindle drive, which extends or shortens the actuating cylinder 13. With its other front end of the actuating cylinder 13 is mounted in a manner not shown on the track plate 7. By shortening the adjusting cylinder 13, the carrier hood 19 including the track milling unit 8 is raised.
