A non-rail bound vehicle, in particular a commercial vehicle or a bus, has a current collector for feeding electrical energy from a two-pole overhead line. The contact wires of the overhead line are configured as forward and return conductors, and each can be contacted by at least one contact strip of the current collector. Due to the fact that the current collector is provided with two support extension arms, which are tiltably and rotatably hinged to both the vehicle and a rocker bearing the contact strips such that the rocker can be both raised and lowered and also can be moved transversely to the direction of travel, the current collector can be safely coupled to and decoupled from the contact wires, even at higher driving speeds of the vehicle. Furthermore, lateral inaccuracies with respect to a lane while steering the vehicle can be permanently compensated for by the current collector.
