A drive arrangement for displacing a contacting device from a raised position to a lowered position includes a four-joint linkage having first, second and third arms interconnected such as to displace the contacting device as the first, second and third arms pivot. An actuator is connected via an actuating lever to the first arm and acted upon by a spring force which counteracts an actuating force applied by the actuator on the actuating lever. The actuating lever is pivotally connected to the first arm and supportable on the first arm via a catch when the first arm is displaced into a raised position and detachable from the first arm when the first arm is displaced into a lowered position, so that the actuating lever assumes a release position in the lowered position of the contacting device, with the contacting device maintained in the lowered position by its weight force.

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.

A motor vehicle has a control device, a first sensor and a global positioning device. The control device has a control unit and a data memory. At least one item of information about an arrangement of an overhead line is stored on the data memory. The control unit is connected to the first sensor and to the global positioning device. The first sensor determines a position of the overhead line relative to the motor vehicle and provides the control unit with the relative position. The global positioning device determines a global position of the motor vehicle and provides the control unit with it. The control unit, on the basis of the established relative position, the established global position and the information about the arrangement of the overhead line, calculates a position of the motor vehicle.
