System adapted for one or more electrically propellable vehicles (contact means)

A vehicle-related arm-shaped contact means comprising a current collector and related to a system for propelling an electrically propellable vehicle, by one or several batteries or a set of batteries, along a roadway, said system comprising

• a) a plurality of roadway sections for subdividing the roadway, wherein each one of the roadway sections comprises one or more elongated tracks or slits, having conductors introduced therein adapted to be supplied with current and put under voltage, connectable via a switch to one or more vehicle-external power sources, including electric stations, for thereby enabling charging of said set of batteries belonging to the vehicle, but primarily driving the vehicle over the set of batteries along the roadway and the roadway sections, and
• b) one or more propellable vehicles which may be driven by means of an electric motor or motors, with each of the respective vehicles comprising a control circuit adapted for necessary distribution of power, and for providing required power and/or speed control, wherein said vehicle is provided on the underneath side with contact means comprising a current collector, displaceable up and down and sideways, in relation to the direction of transportation of the vehicle,
• wherein said elongated track or tracks and the conductors extend along the roadway and the roadway sections, and wherein said contact means is coordinated with a vehicle-related control equipment for bringing the contact means into mechanical and electrical contact with said conductors,
• wherein coordination between the conductors arranged in the roadway section and the contact means of the vehicle occurs via the current collector, in the form of contact springs, adapted for mechanical and electrical cooperation with respective ones of the conductors,
• wherein said contact means with the current collector is adapted to run freely along the track, oriented along the roadway,
• wherein said current collector comprises a main portion, made of an electrically insulating material, said main portion having a lower surface facing towards a contact surface of the conductor, which is to be put under voltage, and being shaped essentially flat, having a lower contact surface formed in said lower surface and consisting of an electrically conductive material,
• wherein the electrically conductive material is adapted to extend through the main portion to form one or more upper contact surfaces and/or connecting conductors on an upper surface of the main portion,
• wherein said contact surface of the conductors is arranged at the respective bottom of the elongated tracks which are arranged in a canalization in the roadway, and
• wherein the main portion comprises a surface extension along the track having a thickness corresponding to the width of the track and having a shape corresponding to the shape of a parallelogram or an oblique parallelepiped.
