  • Patent number: 10974618
    Abstract: An insulating track segment for a ground power supply system includes a body made of an electric current insulating material. The insulating track segment constitutes a portion of an insulating track for forming a continuous sliding surface for a pad of a vehicle powered by the ground power supply system.

  • Patent number: 10940762
    Abstract: This assembly, which includes a ground level power supply system of the type using conduction, including conductive tracks arranged on a roadway, and an electric vehicle, capturing electric energy from said tracks it moves on the roadway, is characterized in that the power supply system includes a ground level antenna, configured so as to have a constant radiation chart along a longitudinal axis of the roadway and emitting a positioning signal, and in that the electric vehicle includes an on board antenna and an on board module, connected to the on board antenna and capable of determining a lateral position of a center of the on board antenna relative to the longitudinal axis from the positioning signal captured by the on board antenna.

  • Patent number: 10857890
    Abstract: The invention relates to a shoe (10) on an electrical power supply track for an electric railway vehicle, the shoe (10) comprising: a power supply flange (12) movable between a retracted position and a deployed position; an actuator (11) able to move the flange between the retracted and deployed positions; and a mechanical system (13) connecting the flange to the actuator; characterized in that the actuator (11): has a movement speed such that it is able to move the flange (12) between its retracted and deployed positions in a time period shorter than or equal to 1 second, and preferably shorter than or equal to 0.5 seconds; and has a number of operating cycles before failure greater than or equal to 2,500,000.

  • Patent number: 10647220
    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.

  • Patent number: 10017077
    Abstract: This support (36), as a profile in an electrically insulating material, comprises a substantially planar upper surface (50), provided with a longitudinal flute (60) intended for receiving a track segment, and a longitudinal groove (70) intended for receiving a low voltage electric power supply cable; and a lower surface (52) intended to bear upon a base for maintaining the support in the roadway. It is characterized in that the lower surface (52) is curved, preferably V-shaped, so that the support is concave so as to be at least transversely maintained in a recess with a mating shape, made in the base.
