Abstract:
1. A rail structure related to a track of a system for propelling an electrically propellable vehicle, by one or several batteries or a set of batteries, along a roadway comprising a plurality of roadway sections, the system comprising: “a” a plurality of roadway portions for subdividing the roadway into said roadway sections, 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, and being connectable via a switch to one or more vehicle-external power sources, including vehicle-external electric stations, for thereby enabling a charging of said set of batteries belonging to the vehicle, but primarily driving the vehicle along the roadway and the roadway sections, and “b” one or more driveable or 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, adapted for creating a required power and/or speed control, wherein said vehicle is provided on its underneath side with contact means 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 creating an adaptation of the contact means so as to at least offer a mechanical and electrical contact with said conductors, wherein coordination between the conductors put under voltage, belonging to the roadway section and the contact means of the vehicle occurs via coordinated current collectors in the form of contact springs, adapted for mechanical and electrical cooperation with respective ones of the conductors put under voltage, wherein the rail structure comprises one or more tracks oriented parallel with external wall sections made of metal, and a partition separating the external wall sections and comprising an intermediate wall made of an electrically conductive material; wherein a first conductor is arranged in a lower portion of a first track delimited by a first external wall section and said partition and a second conductor is arranged in a lower portion of a second track delimited by a second external wall section and said partition wherein the first track comprises a first electrically insulating layer applied to surface portions facing each other of said first wall section and the partition, the first insulating layer being coordinated with the lower portion and intended to support the first conductor, wherein the second track comprises a second electrically insulating layer applied to surface portions facing each other of said second wall section and the partition, the second insulating layer being coordinated with the lower portion and intended to support the second conductor.
