Definitions
- the present patent application relates to the field of running tracks for vehicles, in particular those which are temporarily placed on the ground, in particular to facilitate the movement of vehicles.
- a track may for example be disposed on soft ground, for example sand, on muddy ground, or even on uneven ground, to create a path for vehicles.
- these tracks are rollable on themselves and have a wound position and an extended position in which said runway extends substantially parallel to the ground.
- These tracks generally consist of rectilinear mats placed end to end in order to constitute a rectilinear path.
- the belt When a path defining a curve or a turn is to be made, the belt must be bent in order to give it the desired curvature.
- This belting poses difficulties because it leads to the appearance of transverse folds on the carpet, which form bumps hindering the advance of the vehicle.
- the appearance of the folds is due to the fact that the carpets are made of materials having a significant lateral rigidity, in particular because of their width.
- An object of the present invention is to overcome the aforementioned drawbacks by providing a rolling track rolling on itself for vehicle to make turns without appearance of folds or bumps.
- the running track according to the invention comprises at least a first track portion and a second track portion, the first and second track portions extending substantially parallel to the ground when the rolling track is in the deployed position, the first and second track portions being connected to each other by a pivot connection having a pivot axis which extends in a direction substantially perpendicular to the rolling face when said runway is in the deployed position, whereby the first track portion is pivotable relative to the second track portion about the pivot axis to form a turn.
- the first track portion is rotated relative to the second track portion about the pivot axis which is perpendicular to the plane of the track.
- the first and second portions of tracks are then pivoted relative to each other while remaining fixed to one another, which makes it possible to deviate very easily the trajectory of the running track, while ensuring the continuity of the taxiway.
- the track is advantageously devoid of transverse folds.
- connection between the first and second track portions constitutes a rotary junction about an axis perpendicular to the track.
- the rolling track may comprise one or more junctions of the same type depending on the radius of curvature and the length of the turn that is desired.
- the invention also makes it possible to form a continuous rolling track comprising several successive turns, notably in "S".
- the pivot connection includes a connecting member for securing the first track portion to the second track portion pivotally about said pivot axis.
- This connecting element is a hinge piece which has preferably, but not exclusively, a cylindrical shape having as axis the pivot axis.
- the connecting element thus has a dual function, namely to maintain together the first and second track portions, and guide relative pivoting between the first and second track portions.
- the pivot connection is disposed at the end of the first track portion and, more preferably, at the ends of the first and second track portions.
- the first portion of the track has a protrusion protruding towards the second track portion, and the pivot connection is located in said protrusion.
- the first track portion has an inner face disposed facing an inner face of the second track portion, the two inner faces defining an overlap zone between the first and second track portions, the pivot connection being located in said overlap zone.
- the connecting element is disposed in the overlapping zone, preferably more preferably in the middle of the width of the first track portion.
- the overlap area is shaped to provide an overlap, both when the first and second track portions are aligned with each other, and when they are rotated one by the other. report to the other.
- An interest is to ensure the continuity of the track throughout the turn.
- the overlap length when the first track portion is in alignment with the second track portion, i.e., in a non-pivoted position is between 0 and one third of the width of the track.
- This overlap not only ensures continuity between the first and second track portions, but also improves the robustness of the runway.
- said overlapping zone advantageously has a coefficient of friction strictly less than that of the rolling face of the rolling track.
- At least one of the inner faces of the first and second track portions defining the overlap zone comprises a layer of a sliding material, for example PTFE or any other material having a low coefficient of friction.
- the layer of sliding material surrounds the pivot connection.
- said layer has an annular shape surrounding the pivot connection, and the connecting element when present.
- the first portion of the track comprises a main portion of rolling and an end portion connected to the portion main portion of rolling way articulated, wherein the pivot connection is located in the end portion.
- An interest is to be inclined, for example raise or lower from the ground, the end portion.
- An interest is to be able to conform the track to the unevenness of the ground.
- the end portion is connected to the main portion of rolling by a hinge whose axis of rotation is perpendicular to said pivot axis.
- the main portion and the end portion of the first track portion comprise reinforcement elements which extend transversely to the longitudinal direction of the first track portion.
- the reinforcing elements therefore have the particular function of reinforcing the junction constituted by the first and second portions of the track.
- the main portion of rolling and the end portion are flexible about an axis transverse to the longitudinal direction of the first portion of the track.
- first and second track portions are advantageously flexible to allow the winding of the rolling track on itself.
- At least the end portion, and preferably the main portion of rolling consists of a textile covered with a polymer layer.
- the invention also relates to a junction for a vehicle running track according to the invention, in which said junction comprises
- the first part comprising a mounting member for mounting a main portion of rolling to said first portion.
- the mounting member thus makes it possible to connect the rolling portion to the second portion. It may be, for example, a hinge connection.
- the first part partially overlaps the second part according to an overlapping zone, the pivot connection being located in said overlapping zone.
- at least one of the first and second parts is made of a flexible material, preferably a textile covered with a polymer layer.
- FIG. 1 illustrates a running track according to the invention, in the deployed position and forming a turn
- FIG. 2 illustrates the rolling track of FIG. 2 in the wound position
- FIG. 3 illustrates, in top view, the junction of the running track of Figure 1, the first and second track portions being aligned relative to each other;
- FIG. 4 illustrates the taxiway of FIG. 3 when the first and second track portions are pivoted relative to each other;
- FIG. 5 is a detailed view of the pivot connection between the first and second track portions.
- FIG. 6 illustrates a variant of the taxiway of FIG. 1.
