Abstract

A carrier for one or several electrically conductive tracks of a ground electric feeding system for a motor vehicle in the form of a strip of electrically insulating elastomeric material, comprising a substantially planar electric feeding surface of the land vehicle, provided with one or several longitudinal grooves, each groove being intended to receive a conductive track, and a surface for securing to a roadway, opposite the electric feeding surface. The carrier has a rectangular cross-section and the electric feeding surface and the securing surface form the long sides of said rectangle.

First claim

The invention claimed is:

1. A carrier for one or several electrically conductive tracks of a ground electric feeding system for a land vehicle in the form of a strip of electrically insulating elastomeric material, comprising:
a substantially planar electric feeding surface of the land vehicle, provided with one or several longitudinal grooves, each groove being intended to receive a conductive track; and
a surface securing to a roadway, opposite the electric feeding surface,
wherein said carrier has a rectangular cross-section and wherein the electric feeding surface and the securing surface form the long sides of said rectangle.

2. The carrier according to claim 1 , wherein the electric feeding surface is provided with exactly three longitudinal grooves for receiving the conductive track.

3. The carrier according to claim 1 , wherein the electric feeding surface is provided with at least two longitudinal grooves, said grooves being situated next to one another and extending parallel to one another.

4. The carrier according to claim 1 , the carrier being a single molded piece.

5. The carrier according to claim 1 , the carrier being made from rubber, such as the ethylene-propylene-diene monomer known under the acronym EPDM.

6. The carrier according to claim 1 , further comprising a water draining device.

7. A rail segment of a ground electric feeding system for a land vehicle, the rail segment including:
a carrier according to claim 1 ; and
a conductive track in each groove of the electric feeding surface, each conductive track being mechanically fixed in its groove.

8. The rail segment according to claim 7 , further comprising a radio antenna or a heating system.

9. The rail segment according to claim 7 comprising exactly three grooves in the electric feeding surface, with a phase conductive track in the first groove, a reverse current 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.

10. A roadway with a ground electric feeding system for a land vehicle, the ground electric feeding system comprising a rail made up of a series of rail segments according to claim 7 , juxtaposed behind one another in a longitudinal direction, the rail being inserted in a trench arranged in the roadway and being fixed in the trench preferably by a bituminous joint.

11. The rail segment according to claim 7 , comprising screws for mechanically fixing each conducting track to its associated groove.
