Definitions

  • the object of the invention is a suspension system of a snow plough used particularly for the snow removal from the surface of roads, yards, car parks and other paved surfaces.
  • the working element is constituted by hydraulically controlled mouldboards
  • swivel-mounted plough blades cause that the plough is resistant to hits against projecting surface irregularities. If bigger irregularities are encountered, the snow ploughs have overload mechanisms which protect the plough against damage.
  • the overload protection is constituted by pins connecting the body with the mouldboard which are destroyed under the influence of the overload and consequently prevent the damage of the snow plough and the cooperating vehicle.
  • U.S. Patent US6594923 shows a plough suspension system in which the hitch is connected with the body by means of one screw element. However, this screw element does not act as overload protection, because in the case of an obstacle, the screw element is not destroyed and does not cause disconnection of the body from the hitch.
  • a suspension system of a snow plough comprising:
  • the solution of the snow plough suspension system having an overload protection mechanism fulfilling the function of an overload safety device safeguards the plough elements against damage because in case of an increase of forces acting on a plough blade the connections of elements connecting the body with the hitch are broken as a result of which the remaining structure is protected against damage.
  • FIG.1 shows a suspension system with an overload protection mechanism in an exploded view
  • Fig. 2 shows a plough suspension system with an overload protection mechanism in a front view
  • Fig. 3 shows a cross-section according to the A-A line of Fig. 2
  • Fig. 4 shows an embodiment of a snow plough with an overload protection mechanism according to the invention.
  • a suspension system of a snow plough contains a hitch connected to the body moving torsionally and vertically with respect to the hitch.
  • the system comprising overload protection consists of the body 1 and the hitch 4 connected to each other by means of two front pressure plates 5 and two rear pressure plates 6 connected by means of connecting elements 7, 8. Between pressure plates 5, 6 , there are plates 1A of the body 1 and plates 4A of the hitch 4, whereas front pressure plates 5 are connected trough plate 4A of the hitch 4 with rear pressure plates 6 by means of connecting elements 7,8 and stabilize plate 1A of the body 1 with plates of the hitch 4, forming a closed frame with an opening in the middle.
  • the size of the plate 1 A of the body 1 is smaller than the opening of the hitch 4, such that, in an overload thrust towards the vehicle, the connecting elements 7,8 and overload protection mechanism break and the plate 1 A of the body 1 can pass through the opening.
  • the mouldboard 2 with the swivel-mounted plough blade 3 is attached to the body 1.
  • the connection of the body 1 with the bearing surface of a hitch 4 is effected by clamping the front pressure plates 5 with the rear pressure plates 6 by means of the connecting elements 7 and 8, i.e. a screw and a nut.
  • the front pressure plates 5 and the rear pressure plates 6 stabilize a plate 1A of the body 1 with plates 4A of the hitch 4.
  • the snow plough suspension system features turning (right-left) and vertical (up-down) tracing.
  • the body 1 transfers the load to the front pressure plate 5 or the rear pressure plate 6, depending on the working direction of the plough. Then the connecting elements 7, 8 and the overload protection are broken, and the plough blade 3 with the body 1 is detached from the hitch 4. It prevents damage to the plough and the vehicle to which it is attached.
