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： An electrically driven vehicle contains a current collector for supplying electrical energy from a bipolar overhead line system. The collector has an articulated support rod, which bears, on the contact wire side, a contact collector having a contact strip, and which is coupled, on the vehicle side, to a lift drive for positioning the support rod and for pressing the contact collector to a contact wire of the overhead wire system, a detection device for detecting a lateral position of a contact point of the contact wire on the contact strip and a driver assistance system for executing an automatic steering intervention as a function of the detected lateral position of the contact point. The vehicle has increased availability for a feed of electrical energy from the overhead line system in that the contact strip is supported on the contact collector via at least two spring elements.
