Definitions

  • the invention relates to a track device for cross-country trails, the skids of which are arranged on a frame for connection to a vehicle, a device for transmitting pressure to the skids being provided between the vehicle and the frame.
  • Track devices of the aforementioned type are used to manufacture cross-country trails. They are mainly manufactured and used as trailer devices for snow groomers and snowmobiles, which are small tracked vehicles with steering skis and motorcycle designs. Cross-country track devices have a skid, under which profile shoes are mounted, which produce the actual track profile of the trail.
  • track devices designed as a trailer device
  • one or two weights are accommodated on the runner in order to press the track shoes into the snow.
  • the skid is then connected to the steering and towing frame, which is still supported on a preliminary skid in the case of trailer devices.
  • the drag frame carries a cutter bar in front of the skid, which is lowered in hard snow to loosen up the snow so that the track shoes can create the track profile.
  • the trailer is connected to the towing vehicle via a drawbar.
  • Trailer devices have the disadvantage that the towing vehicle cannot reverse with the trailer track device and that each use for preparing a cross-country trail is associated with a labor-intensive unloading and loading process. In addition, it is hardly possible to change the weight of the skid during use.
  • the special advantage of the trailer devices is their universal applicability, since they can be towed by any suitable vehicle, which is why they are increasingly being used.
  • the steering frame is connected to the towing vehicle via a joint (ball or universal joint).
  • a hydraulic cylinder which is supported on the towing vehicle, usually acts on the steering frame.
  • the penetration depth of the track device can be adapted to the respective snow quality, on the other hand, the track device can also be pivoted into the rest position by means of the hydraulic cylinder when it is not in use. It is therefore possible to leave such attachment track devices on the towing vehicle.
  • the add-on tracker is controlled from the control station of the towing vehicle.
  • the above-mentioned advantage is offset by two disadvantages in conventional devices, namely that the device can only be used in conjunction with a vehicle equipped (hydraulically) for the actuation of the track device and furthermore the possibility of movement of the track device is impaired by the incompressibility of the hydraulic fluid so that the known devices can follow bumps on the trail hardly or only to an insufficient extent.
  • complex and expensive hydraulic systems were required.
  • the aim of the invention is now a cross-country track device which combines the advantages of the trailer device with those of the attachment, without having their disadvantages.
  • This goal is achieved in a track device of the type mentioned at the outset if the pressure device is designed as a coil spring or as a torsion spring.
  • the inventive design of the tracking device makes it possible for the device to follow bumps almost exactly, the desired contact pressure being able to be kept almost constant over a wide range.
  • a favorable kinematics is achieved if, in a further development of the invention, both in the construction with coil spring and in the construction with torsion spring, a spring end on the frame, which e.g. is designed as a steering frame that can be coupled to the vehicle, is supported and with the second end the support is provided on a handlebar that engages with the runner, which is connected via a coupling, the length of which can be changed arbitrarily for the purpose of arbitrarily changing the tension of the coil spring or the torsion spring the vehicle, in particular with its clutch, is connected.
  • a particularly preferred, simple design, which does justice to the harsh weather conditions under which track devices are used, is characterized in that the torsion spring in a manner known per se from two non-circular ones, in particular.
  • the torsion spring in a manner known per se from two non-circular ones, in particular.
  • the guide surfaces are arranged diverging downwards (against the floor).
  • a steering frame 2 On a runner 1, which carries track shoes 21, sits a steering frame 2, which is connected on the one hand to the runner 1 via a pivot axis 3 and on the other hand to a coupling 8 on the towing vehicle 23 via a joint 4.
  • Rubber-elastic bushes 5 which act as torsion spring elements, serve to adjust and stabilize the runner 1.
  • the steering frame 2 carries, in addition to a knife bar 9 which can be actuated by means of a lever 11 for tearing open any ice layer on the track, an electro-spindle cylinder forming a coupling rod 14, which at one end has a universal joint 16 with the coupling 8 and at its other end a Ball joint 15 is connected to a handlebar 12.
  • the link 12 is connected via a joint 6 to a spring cylinder 20, which in turn is connected via a bar 19 and a joint 7 to the frame designed as a frame 2.
  • the spring cylinder 20 consists of the actual cylinder, a piston rod 13 and a compression spring 10.
  • the force exerted by the spring cylinder on the handlebar 12 is transmitted to the crank (spindle cylinder) 14, which is connected via the joint 15 and the universal joint 16 to the clutch 8 and thus to the towing vehicle 23 .
  • the clutch 8 is rigidly connected to the towing vehicle 23
  • the spring cylinder 20 is more or less pretensioned when the length of the spindle cylinder 14 changes, so that the track device is pressed into the snow when the spindle cylinder is extended, the pressure force of the skid 1 being proportional to the snow the bias of the spring cylinder 20.
  • the spring cylinder 20 is arranged so that it allows vertical movement of the runner or the track device without a substantial increase in the force required for this, the track device can easily and precisely follow uneven floors.
  • the kinematic interpretation of the Quadrilateral joints can be designed in both embodiments so that the contact pressure of the runner 1 changes only slightly during the vertical movements in the operating area.
  • the spring cylinder 20 is replaced by a torsion element, a so-called roster element.
  • This element has two elongate, non-circular, in the exemplary embodiment shown square cross-section having tubular elements 17, 24.
  • the tubular element 17 engages in the tubular element 24.
  • the inner tube element 17 is supported by rubber rollers 25 against the inner wall of the outer tube element 24.
  • the outer tubular element 24 is fixed to the handlebar 12, the inner tubular element 17 is fixed to the frame (steering frame 2).
  • the construction elements 12 and 14 can also be attributed to the vehicle.
  • the coupling 8 has guide surfaces 22 in the manner of a backdrop. Between the guide surfaces 22 there is a roller 18 mounted on the steering frame 2, which in the working position of the track device is sufficiently spaced from the guide surfaces 22 to ensure that the track device can follow the towing vehicle 23 like a trailer when tracking.
  • the guide surfaces 22 diverge from each other against the ground, so that in the raised position (rest position) the roller 18 has practically no play with respect to the guide surfaces 22.
  • the clutch 8 therefore has a centering function for the tracking device (centering clutch).
