TORQUE OF ELECTROMECHANICAL ACTUATOR FOR TRAM PANTOGRAPH CALCULATION

B. A. Lopatin, D. N. Kazartsev

Abstract


Electromechanical drive torque of the 3-bar planar lever mechanism of a pantograph
is designated for tram current pick-off and electric power supply from the contact
system. In the process of lifting and lowering of the mechanism it is necessary to provide the torque change law required depending on the turning angle of adriving bar.
