    Support for conductive tracks in elastomer with rectangular section for electrical power supply system from the ground
    The present invention relates to a support for one or more conductive tracks of electric current from a ground power supply system for a land vehicle, in particular a motor vehicle, in the form of a strip of an electrically insulating elastomeric material, comprising a substantially planar land vehicle electrical supply surface, provided with one or more longitudinal grooves, each groove being intended to receive a conductive track, and a surface for securing to a road pavement, opposite the surface power supply.
    Such a support 36 is known from document FR 3 017 342 A1. The disadvantage of this support 36 is its complex integration in the pavement 12 of a road. Indeed, due to the “V” shape of its lower surface 52, this support requires a concrete base 22 with an upper surface of “V” shape complementary as an interface for securing to the roadway.
    The document FR 3 019 113 A1 describes another system for feeding by the ground with supports 25, 26 of conductive tracks 11, 12 in the form of profiles. This document also provides for a concrete seal 7.
    Document US 383,274 describes elastic rubber bands u, u ’carrying conductive segments t. However, this known solution is intended for integration into railway sleepers A and is not suitable for integration into a roadway.
    An object of the invention is therefore to provide an improved conductive track support which can be integrated quickly and easily into a road pavement.
    According to the invention, this object is achieved with the support as defined above, characterized in that said support has a cross section in the shape of a rectangle and in that the electrical supply surface and the joining surface form the sides. along said rectangle.
    By providing a rectangular cross section of the support, it can be placed and fixed directly in a trench with a rectangular cross section complementary to the roadway. Such a trench is easily achieved by milling the pavement with a milling machine. Since the power supply surface and the joining surface form the long sides of said rectangle, the support is thin. Thus, the milling of the pavement can be limited to a shallow depth, which simplifies milling.
    According to preferred embodiments, the support according to the invention comprises one, several or all of the following characteristics, according to all the technically possible combinations:
    - the power supply surface is provided with exactly three longitudinal grooves for receiving the conductive track;
    - The power supply surface is provided with at least two longitudinal grooves, said grooves being located one next to the other and extending parallel to each other;
    - the support is in a single molded part;
    - The support is made of rubber, such as ethylene-propylene-diene monomer known by the acronym EPDM;
    - a water drainage device.
    The invention also relates to a rail segment of a ground power supply system for a land vehicle, in particular a motor vehicle, the rail segment comprising a support as defined above, and a conductive track. in each groove of the electrical supply surface, each conductive track being mechanically fixed in its groove, in particular by screwing.
    Preferably, the rail segment according to the invention comprises one, several or all of the following characteristics, according to all the technically possible combinations:
    - a radio antenna and / or a heating system;
    - exactly three grooves in the power supply surface, with a phase conductive track in the first groove, a current return conductive track in the second groove and a neutral conductive track in the third groove, the phase conductive track preferably being arranged between the other two tracks.
    The invention also relates to a road pavement with a rail of a ground electrical supply system for a land vehicle, in particular a motor vehicle, the rail being composed of a series of rail segments as defined. above juxtaposed one behind the other in a longitudinal direction, the rail being inserted in a trench formed in the roadway and being fixed in the trench preferably by a bituminous joint.
    The invention will be better understood on reading the following description given solely by way of illustration, with reference to the single figure which represents a cross section of a road pavement according to the invention.
    With its experience in the field of ground supply systems known by the acronym of APS systems, of the conduction type, for guided electric vehicles, that is to say forced to move along tracks , (in particular trams traveling along railways), the applicant has developed the present system of ground supply for unguided electric vehicles.
    In the figure is shown a car 1, as an unguided electric vehicle, traveling on a roadway 2.
    A XYZ trihedron is conventionally associated with car 1: the X axis in the longitudinal direction, facing forward; the Y axis in the transverse direction, oriented from left to right; and the Z axis in the vertical direction, oriented from bottom to top.
    Car 1 has a body 4 and wheels 3, some of which are steerable. The car 1 comprises steering means (not shown) allowing a driver to modify the angle of the steered wheels in the XY plane so as to steer the vehicle 1.
    Car 1 has a rechargeable battery and an electric motor (not shown).
    Car 1 is equipped with a capture means making it possible to collect electrical power during the movement of car 1. The capture means are generally referenced by the number 5.
    The capture means 5 comprises a pad 0 suitable for being put in sliding contact on a pair of feed tracks of the feed system by the ground, which will now be described.
    Pavement 2 has a trench 6 inside which is positioned the ground feeding system, generally referenced by the number 10.
    Once the system 10 is positioned in the trench 6, the upper surface 8 of the roadway 2 is continuous over the entire width of the latter. The upper surface 8 is substantially flat.
    In position, the system 10 presents, flush with the surface 8 of the roadway 2:
    - A phase conducting track 11, intended to be electrically connected to a source of electrical power, delivering for example a potential V s of +750 V DC;
    - a neutral conductive track 12, intended to be electrically connected to a reference potential V ref , for example of 0 V;
    - a conductive current return track 13.
    The phase 11 track has a width of approximately 5 cm and a length of several meters. The exact length depends on the type of application.
    Advantageously, the neutral 12 and current return tracks 13 are produced in an identical manner to the phase track 11.
    The neutral 12 and current return 13 tracks run parallel to the phase track 11, on each side of the latter. The side edges of the phase track 11 and the side edges of the neutral track 12 and the current return track 13, which are opposite one another, are spaced a distance of 12 to 15 cm.
    According to the invention, said tracks 11, 12 and 13 are inserted in longitudinal grooves 14 formed in an electrical supply surface 15 of a support for conductive tracks 16. The grooves 14 are located next to each other and s 'extend parallel to each other.
    The support 16 has a rectangular cross section S. It is molded in one piece and made of an electrically insulating elastomeric material. Preferably, the material is a rubber, such as ethylene-propylene-diene monomer known by the acronym EPDM.
    The support 16 is in the form of a parallelepiped strip. Advantageously, this strip has a length of approximately 3 m and a width between 40 and 50 cm.
    The support 16 is secured to the bottom 17 of the trench 6 by its lower joining surface 18. The joining surface 18 is opposite the feeding surface 15.
    It will be noted that the supply 15 and securing 18 surfaces form the long sides of the rectangle forming the cross section S. Thus, the support 16 has a small thickness E, preferably about 8 cm.
    Preferably, the support 16 comprises a water drainage device. This device makes it possible in particular to evacuate rainwater to avoid current leaks from the conductive track 11 towards the tracks 12 or 13.
    The support 16 and the conductive tracks 11, 12 and 13 together form a rail segment 19. The rail segment 19 may comprise a radio receiving and / or transmitting antenna allowing radio communication with the car 1. A system of heating, for example, electric, can also be integrated in the rail segment
    19. Such heating prevents the formation of frost in winter.
    A series of rail segments 19 can be juxtaposed one behind the other in the longitudinal direction X in the trench 6 in order to form a supply rail.
    The rail segments 19, and therefore the complete rail, are fixed in the trench 6 with the aid of an adhesive, for example a bituminous joint 20. The adhesive 20 is placed on the walls of the trench 6.
    The installation of a rail according to the invention in a pavement 2 is very easy. It is enough to machine the pavement asphalt, for example by milling, to create the trench
    6. Once the trench has been made, the bituminous seal is placed on the walls of the trench 6. Then, the supports 16 are inserted one behind the other in the trench 2. The supports 16 are fixed in position by bituminous glue. Finally, the conductive tracks 11, 12 and 13 are inserted into the grooves 14 and fixed there, for example using screws.
    The present invention has the following advantages in particular:
    A single continuous support 16 integrating the three phase tracks, current return and neutral;
    The parallelepiped shape of the support 16 is particularly suitable for integration into an asphalt road;
    - The formation of cracks in the road is avoided, in particular thanks to the materials used.
