ABSTRACT:
A current collector is provided for transmitting energy between a contact wire and a motor coach. The current collector has a first support am (11) connected to the motor coach and being raisable about a first horizontal axis (28); and a pair of second support arms (8 and 18) connected to the free end of the first support arm rotatably about a second horizontal axis (28). The pair of the second support arms (8 and 18) is connected to an extension element (14) protruding over the second horizontal axis (28). Further, the current collector has a guide bar (13) rotatably connected with the motor coach and the extension element (14); and at least one collector shoe which is supported on the free end of the pair of the second support arms (8 and 18). The extension element (14) is connected to each of the two second support arms (8 and 18) via a torsional actuator (16 and 17, respectively) being arranged on the second horizontal axis (28). A control device (25) is provided which controls the two torsional actuators (16 and 17) dependent on the signal (21, 22) of at least one displacement, acceleration or force sensor arranged on the current collector.
