ABSTRACT:
The invention relates to a ground-level multipole current supply system for track-guidable, rubber-tired, electrically propulsive vehicles, wherein extruded aluminum profiles are provided within an electrically insulating duct-like shielding for each pole. To permit the current supply system to be kept small and easily installable the shielding is constructed as a self-supporting extruded profile which is fastened, suspended with ducts open downwards, on support arms. The substantially triangular live rails are retained screwlessly by sliding axially behind beads in the shielding. A vee-shaped arrangement of the contact tracks of the two live rails and of the two contact pieces on the current collector side exerts a self-centering influence upon the current collector head, so that the latter can be of simple construction and only little play need be provided for relative movements between current collector head and live rails.
