Abstract: A non-rail-bound vehicle, truck or bus, includes a current collector feeding electrical energy from an overhead line installation having a contact wire. The collector has a contact strip with a working region contacting the contact wire. An actuating device coupled to the collector adjusts the contact strip. The contact strip is horizontal and adjustable transversely to a vehicle longitudinal axis. A sensor senses the position of the vehicle relative to the contact wire. A control device connected to the sensor and the actuating device actuates the actuating device based on the sensed vehicle position, so that the contact strip maintains contact with the contact wire within its working range. The vehicle thus reliably maintains contact with the contact wire through the collector during operation on multilane roadways with an at least partially electrified lane, even at relatively high speeds of, for example, 80 to 100 km/h.

Abstract: 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.
