The aim of the invention is to develop a device and a method for controlled current collection between a contact wire and a track-bound, electrically operated high speed vehicle. The streamline housing (3) that is mounted on the vehicle roof consists of telescopically guided inner and outer cover segments (5) with a cover roof (6) which is moulded to the inner cover segment. The cover segments (5) are moved in and out to different lifting heights by at least two lifting devices (29) which are located in the interior of the housing and which are operated with an electromechanical drive. Said electromechanical drive is arranged horizontally in relation to the insulator axis B-B and the lifting devices (29) and all other built-in parts are vertically enclosed by the cover segments. The rocker (46), with the wearing strip (48) and the insulator (11), can be moved vertically in relation to the lifting heights of the cover segments (5) and rotated about the insulator axis B-B by means of a high-frequency drive (71). |
