摘要： A current collector for a non-rail-bound, electric traction vehicle has an articulated support linkage, which, on the contact wire side, supports rocker assemblies with contact strips and, on the vehicle side, has a base joint for articulation to the traction vehicle. A pneumatic reciprocating drive is coupled to the support linkage for raising the rocker assemblies from a lower parking position into an upper contact position when the reciprocating drive is pressurized and for lowering into the parking position under its own weight when depressurization occurs. An exhaust air line connects the reciprocating drive to the environment to lower the rocker assemblies. An air accumulator and a downstream throttle valve are connected between the reciprocating drive and an environment opening of the exhaust air line. The rocker assemblies can be quickly lowered and nevertheless brought into the parking position without damage in order to disengage the current collector.

摘要： A method and a device test whether there is contact between a current collector and a contact wire of an overhead line. The current collector is located on a motor vehicle driven by an electric motor, and the contact wire extends in a direction of travel. The current collector has two contact regions oriented transversely to the direction of travel which are arranged one behind the other in the direction of travel and on each of which an end contact element is located. A pair of end contact elements located on the same side is connected to a measuring device and an electrical state variable is detected by the measuring device. Subsequently, it is determined in accordance with the detected state variable whether the pair of end contact elements is in contact with the overhead line.
