A current collector for a non-track-bound, electrically driven vehicle for feeding electrical energy from a two-pole overhead line system with two contact wires. Two upper arms are rotatably connected to an adjustable lower arm by toggle joints. Each upper arm carries a contact rocker for contacting the contact wires. Coupling bars are rotatably connected to the upper arms and articulated so that adjustment of the lower arm forces adjustment of the upper arms. A compensating rocker compensates for a height difference between the contact rockers with a rocker stand and a rocker beam. The rocker stand can be rotatably connected to the vehicle and the rocker beam is connected to the coupling bars by way of compensating joints on either side of the rocker joint. At least one stop element limits a rotational movement of the rocker beam about a rocker joint axis of the rocker joint.

Current collector and non-track-bound, electrically driven vehicle with a current collector of this kind

A current collector for a multi-pole contact line system has a lower arm that is pivotally mounted on a base and at least two upper arms that are pivotally mounted on an end of the lower arm opposite the base. The current collector also has at least two contact assemblies that are arranged on the respective upper arms and are associated with separate different poles of a contact line. The current collector further has a central compensating rocker arranged on the base and at least two connecting rods, the first end of each of which is pivotally connected to the central compensating rocker and the second end of each of which is pivotally connected to one of the at least two upper arms. An electrified transport system uses such a current collector.

Current collector for multi-pole contact line system

A vehicle control facility for the automated control of an electrical road vehicle for a route system with an energy-supply system that includes a lane-bound energy supply line, in particular an overhead line system. A position-determining unit determines a geographical position of the electrical road vehicle. A specific-lane-determining unit determines position data for a specific lane assigned to the lane-bound energy supply line. A communication interface transmits current relative positions of infrastructure features with respect to the electrical road vehicle to an external central specific-lane-determining facility and receives position data. A vehicle-control unit controls the electrical road vehicle with respect to the determined specific lane in dependence on the determined relative position of the specific lane.

Vehicle control system and method for automated driving of a specific lane for continuous supply with electrical energy

A transportation system with a non-rail-bound, electrically or diesel-electrically driven vehicle, has a two-pole overhead conductor system with contact wires forming supply and return conductors. The vehicle has a current collector for the supply of electrical energy through sliding contact with the contact wires. A video detector on the vehicle determines a position of the contact wires relative to the vehicle. Marking elements mark the position of the contact wires. The video detector is oriented for taking video images of the marking elements, and an evaluation unit recognizes from a recorded video image whether contact wires are present above the vehicle and, when they are present, determines their position relative to the vehicle. Through the improved recognition of the position of the vehicle relative to the overhead conductor the operational safety of the transportation system is improved.

Transportation system with a non-rail-bound vehicle to be supplied with electrical energy through an overhead conductor system

A non-rail-bound vehicle, in particular a truck, includes a current collector for supplying electric energy from a two-pole overhead conductor. A rocker can be vertically lifted or lowered by a rocking movement of a support extension arm about horizontal tilting axes of lower hinge assemblies and can be laterally displaced by a tilting movement of a support extension arm about vertical pivot axes of the lower hinge assemblies. The lower hinge assemblies are supported on a lifting device which is connected to a vehicle frame of the vehicle and through which the current collector can be vertically moved between a lower parked position and an upper operating position. In this manner, overhead conductors with an extended height range can be contacted without the current collector influencing the entire length of the vehicle.

Non-rail-bound vehicle

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.
