MEASURING CURRENT COLLECTOR OF ELECTRIC ROLLING STOCK Russian patent published in 2022 - IPC B60L5/32 G01M17/08 

FIELD: current collectors.

SUBSTANCE: invention relates to current collectors of electric rolling stock. The measuring pantograph of the electric rolling stock contains a base, a pressure pneumatic actuator, a pneumatic line, a hinged frame, a carriage with a skid and removable weights with the possibility of their fixation at any point of the hinged frame. The pressure pneumatic drive is connected to the pneumatic line and is articulated with a hinged frame, on which a carriage with a skid is installed, equipped with elastic pneumatic elements. The cavities of the pneumatic elements of the carriage are connected to the pneumatic line through the control valve and the pressure regulator in the pneumatic elements of the carriage. In this case, the measuring current collector contains a pressure control unit in the pressure pneumatic drive, built into the pneumatic line, and a control unit. The outputs of the control unit are connected to the inputs of the pressure regulator in the pneumatic elements of the carriage and the pressure control unit in the pressure pneumatic actuator.

EFFECT: expanding the functionality of the measuring pantograph of the electric rolling stock.
