  • the first axis and the second axis form a first pair of axes and the third axis and the fourth axis form a second pair of axes, each with axes running parallel to one another.
  • the device adapter has a vertical axis for pivotally fixing the road service device so that the snow is conveyed to the side of the road and thrown off. In the vast majority of cases, it is also necessary to tilt the road service device around a horizontal longitudinal axis in order to be able to clear roads that are cambered or slope to one side.
  • the connection of a snow plow to the corresponding towing or pushing vehicle has a decisive influence on the clearing results and the driving behavior of the vehicle equipped with the snow plow.
  • the device for fixing a snow plow on a vehicle should be as short as possible when viewed in the direction of travel in order to keep the axle loads occurring on the vehicle as low as possible.
  • the smooth running of a snow plow it is to be considered advantageous if the upper links and the lower links are as long as possible compared to the overall length of the device.
  • the present invention is therefore based on the object of making the upper link and lower link as long as possible with the shortest possible overall length of a device of the type mentioned in order to achieve the two advantageous effects mentioned to the same extent as possible.
  • a device of the type mentioned is therefore further developed in such a way that the vertical axis intersects at least one axis of the second pair of axles or runs between at least one axis of the second pair of axles and the first pair of axles.

  • the equipment carrier is supported as widely as possible on the mounting plate, so that any tendency to tilt to the side is effectively counteracted.
  • the invention is preferably further developed in this context in such a way that the upper link and the lower link each combine on the equipment carrier side to form a common upper link and a common lower link .
  • the present invention provides that the vertical axis runs between the upper links and the lower links.
  • the force that acts on the device according to the invention when snow is pushed aside by a snow plow is, according to this embodiment, transmitted centrally to the two upper links and lower links and can be transferred to the mounting plate with the lowest possible moments.
  • the present invention can preferably be further developed in such a way that the device adapter is pivotably mounted on the device carrier on a fifth horizontal axis, which is transverse to the axes of the Axle pairs runs.
  • This fifth horizontal axis thus runs in the longitudinal direction of the device according to the invention or of the vehicle and allows the snow plow to be tilted to suit inclined roadways.
  • the device adapter and the device carrier each form a box, the box of the device adapter being inserted into the openings for the passage of the vertical axis of the device carrier, and the fifth axis being formed on the bottom of one of the two boxes is and engages in the bottom of the other of the two boxes and wherein the device adapter and the device carrier have connecting means which can be brought into engagement with one another in an area between at least one axis of the second pair of axles and the first pair of axles, which connecting means enable the device adapter to be pivoted relative to the device carrier by the fifth allow horizontal axis.
  • the fifth axis is only formed by a point of application on the bottom of one of the two boxes and the forces to be transmitted with the fifth axis, the longitudinal axis, are directed around the vertical axis by means of the boxes.
  • the boxes are built in the area between the pairs of axles, which results in a short overall length compared to the extension of the upper and lower links.
  • the boxes are held together by the connecting means.
  • the curved elongated hole has a curvature that corresponds to the circular path that the device adapter describes with respect to the device carrier when tilted.
  • the connecting means are formed by curved elongated holes and bolts passing through the elongated holes.
  • the elongated holes can be arranged on the device carrier or on the device adapter; in any case, a bolt must be provided on the other part of the group consisting of the device carrier and device adapter, which passes through the elongated hole and is secured in the elongated hole with a nut.
  • the upper link and lower link can be driven for pivoting by means of at least one hydraulic cylinder.
  • the drive by means of hydraulic cylinders is particularly powerful, insensitive to shocks and impacts that act on the device according to the invention from the snow plow, and can also use a hydraulic system that is usually found on push or towing vehicles, usually trucks , available.
  • the tilting movement about the fifth horizontal axis is carried out by a hydraulic cylinder.
  • the present invention is preferably further developed in such a way that at least one hydraulic cylinder is mounted on the device adapter and can be connected to a road service device, in particular a snow plow, which is pivotably attached to the device adapter.
  • a road service device in particular a snow plow, which is pivotably attached to the device adapter.
  • the snow plow can be pivoted about the vertical axis to the sides of a road in order to convey snow next to the road.
  • the device according to the invention further comprises a support frame for fixing the road service device and is characterized in that the support frame is pivotally articulated on the device adapter and is arranged in such a way that the support frame intersects at least one axis of the second pair of axles or at least between an axis of the second pair of axles and the first pair of axles.
  • the support frame does not extend beyond the parallelogram linkage, which is limited by the first and second pairs of axles, so that the upper link and lower link essentially extend over the can extend the entire length of the device according to the invention.
  • the upper link and lower link can preferably extend over 95% of the total length of the device in the device according to the invention.

  • the vertical axis 20 is now arranged on the device adapter 13 and intersects the axes 18 and 19 in the embodiments shown in the figures. However, within the scope of the present invention, it would also be conceivable for the vertical axis 20 to run between at least one axis 18 or 19 of the second pair of axles B and the first pair of axles A. In this way, with essentially the same overall length of the device 10, a relatively longer extension of the upper link 14 and lower link 15 results, whereby the advantages described above are achieved.
