System adapted for one or more electrically propellable vehicles (a snow plough arrangement)

A vehicle-related snow plough arrangement comprising at least one snow plough unit and 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” a plurality of roadway portions for subdividing the roadway into said roadway sections, wherein each one of the road 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 the 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,
• wherein the snow plough unit is designed as a cleaning means, adapted to clear the track from loose obstacles, such as ice, snow, water, sand, gravel, and yield to solid obstacles,
• wherein the snow plough unit is adapted to be rotatably attached to the contact means in an upper area about a horizontally disposed axis of rotation,
• wherein the snow plough unit and said axis of rotation are movably disposed in a vertical direction by means of a resilient member, and
• wherein the snow plough unit is oriented in the direction of transportation of the vehicle and comprises a forwardly directed edge portion, said edge portion comprising a point, which may be brought into contact with the bottom of the track and/or the conductor.
