Abstract:
1. A vehicle-related arm-shaped contact means related to an arrangement or 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 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, slits or grooves having conductors introduced therein adapted to be supplied with current and put under voltage and being connectable over 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 one or more driveable or powerable 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 creating a required power and/or speed control, wherein an underneath side of said vehicle is provided 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 wherein said contact means is coordinated with 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 adapted for mechanical and electrical cooperation with respective ones of the conductors put under voltage; wherein the vehicle-related contact means comprises at least one elongated arm having a first end portion rotatably attached to the underneath side of the vehicle at a laterally fixed position relative to the vehicle such that the elongated arm may be rotated with respect to the vehicle about a vertical axis of rotation, and a second end portion supporting said contact means; wherein one or more sensors are arranged on the lower portion of the vehicle to sense the existence of and the orientation of the track belonging to the road section and to transfer sensed information to the control equipment; wherein the control equipment comprises a control circuit which, in response to a sensed existence of and sensed orientation within a defined area of coverage, is adapted to actuate a means adapted to horizontally move and/or lowering or elevating the contact means; wherein said contact means has an elongated extension and is rotatably attached to the second end portion of said elongated arm about a vertical axis of rotation; wherein the contact means is adapted to be maintained in parallel to a vertical plane passing through the vehicle and parallel to the direction of transportation of the vehicle, regardless of the angle between the elongated arm and the vertical plane passing through the vehicle.
