Abstract: 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.
