Definitions

  • the present invention relates to a snow removal device suitable for any vehicle. However, for conditions of intensive use, a vehicle with all-wheel drive is recommended.
  • the device presented eliminates these drawbacks. Indeed, the design of the blade validates the homogeneity of the device as a whole which simultaneously generates its operation and its own safety, according to an isostatic mechanical system. The design of this device thus makes it possible to limit the number of mechanical parts, and therefore the weight. It avoids the need for complex, generally hydraulic, equipment.
  • the device presented makes it possible on the one hand to keep, whatever the slope conditions, a permanent contact with the ground, and on the other hand, not to create a torsional stress on the structure of the vehicle.
  • the design of the device allows absorption of any shocks received by the blade. This same design preserves the traction of the vehicle since it repels snow more on the evacuation side, whatever the side chosen for the orientation of the blade, left oblique or right oblique, or even frontal position.
  • An intermediate fixing frame allows rapid assembly and disassembly and therefore punctual use of the assembly.
  • This framework also allows adaptation on all vehicles without disfiguring them, while leaving them conform to. the legislation.
  • the high position of the blade is obtained by manual lifting which allows the lightness of the whole.
  • the blade (1) a device commonly known under the name of "bias blade” is in the form of a rectangular plate curved transversely and identically over its entire length, the direction of the length being parallel to the ground and the plane comprising the two longitudinal ends of the concave plate being substantially perpendicular to the ground.
  • the convex part of the blade (1) faces the front of the pusher vehicle.
  • This blade (1) comprises in its lower part and on the convex side a spar (2) parallel to the length of the blade (1).
  • On the upper part of this spar (2) is fixed in its middle a sphere (3) close to the blade (1), this sphere (3) being extended in its lower part by a cylinder being housed in a bore in the beam (2), the axis of this bore being substantially perpendicular to the ground.
  • the blade (1) comprises in its upper part and on the convex side a shaft (4) parallel to a length of the blade (1), the longitudinal center of the shaft (4) being perpendicular to the center of the sphere (3), this shaft (4) being connected at its ends to the blade (1) by two fixing lugs (5) (6), the shaft (4) remaining close to the blade (1).
  • a nut (7) having a bore receives the shaft (4) in the middle, this nut (7) itself comprising at its upper and lower ends two aligned axes (8) (9) perpendicular to the longitudinal axis of the shaft (4) and substantially perpendicular to the ground.
  • a yoke (10) is articulated around the axes (8) - (9) of the nut (7).
  • a shaft (II) is fixed to the yoke - (10) perpendicular to the axes (8) (9) and substantially perpendicular to the shaft (4).
  • a rectangular frame (12) whose length is parallel to the ground and the width perpendicular to the ground, fixed in a frontal position at the front of the pusher vehicle and centered on it, is provided with two lower yokes (13) (14) and two upper yokes (15) (16) at its four angles, the axes of articulation of these four yokes (13) (14) - (15) (16) being parallel to the length of the frame - (12) and contained in a plane parallel to the plane formed by the frame (12) and directed towards the convex part of the blade (1).
  • Two arms of the same length (17) (18) receive at their junction two rings with spherical bearing (19) (20) fitting onto the sphere (3), the free ends of the two arms (17) (18) articulating respectively on the two lower yokes (13) (14) of the frame (12)
  • Two arms of the same length (21) (22) have at their junction a bore whose axis is the bisector of the angle formed by the two arms - (21) (22) at their junction, the two free ends two arms (21) (22) respectively joining the two upper yokes (15) (16) of the frame (12).
  • the shaft (4) On either side of the nut (7) and between the fixing lugs (5) (6), the shaft (4) receives two elastic elements (23) (24).
  • An elastic element (25) is inserted between the bore of the junction of the arms (21) (22) and the free end of the shaft (11).
  • a bar (26) parallel to the length of the frame (12) connects the upper arms (21) (22) near the shaft (11).
  • This bar (26) receives in its center a yoke (27) whose axis of articulation is parallel to the bar (26) and close to the latter, this yoke (27) being directed towards the side of the frame (12) .
  • the frame (12) receives in the middle of the lower bar a yoke (28) whose articulation axis is parallel to the lower bar of the frame (12) and this, this yoke (28) being directed from the side of the blade (1).
  • a strut (32) provided with a ball joint at each of its ends connects the arm (17) near the frame (12) to the upper part of the beam (2) and towards its end located on the same side as the arm (17).
  • This strut (32) can also connect the lower arm (18) to the opposite end of the beam (2).
  • the nut (7) can be replaced by a sphere (33) comprising a diametral bore receiving the shaft (4), the yoke (10) being replaced by a part (34) comprising two rings with spherical bearing (35) (36 ) fitting onto the sphere (33).
  • the shaft (11) remains linked on the part (34) in the same way as on the yoke (10).
  • connection between (1) (2) (3) and (17) (18) is a ball joint.
  • connection between (4) and (7) is a sliding pivot
  • connection between (7) and (10) is a pivot.
  • the link between (10) (11) and (21) (22) (26) is a sliding pivot.
  • connection between (27) and (28) is a pivot.
  • the link between (29) and (30) is a pivot
  • connection between (30) and (28) (12) is a pivot.
  • the link between (17) (18) and (12) is a pivot
  • the link between (21) (22) and (12) is a pivot
