ELECTRIC ROLLING STOCK CURRENT COLLECTOR Russian patent published in 2025 - IPC B60L5/26 B60L5/32 

FIELD: electric rolling stock current collectors.

SUBSTANCE: current collector of electric rolling stock includes lower movable frame, on which there is an upper movable frame and a skid fixed on the upper movable frame by means of carriages. At the same time the lower movable frame lifting and lowering mechanism and the upper movable frame pressing mechanism, made in the form of elastic pneumatic elements, are connected to the compressed air source through pressure regulators and are pneumatically connected to each other. Both regulators are connected to the control unit, the input of which is connected to the output of the speed sensor of the electric rolling stock, the operator’s panel and the output of the contact pressure sensor placed on the skid. On the base there is a stop-limiter of the lifting height of the lower movable frame, which is equipped with a pneumatic drive; at that, the cavity of the pneumatic drive is connected to a source of compressed air through a controlled valve, the input of which is connected to the control unit. Elastic pneumatic element of upper movable frame is installed in aerodynamically streamlined housing.

EFFECT: improving the quality of current collection of the current collector of electric rolling stock.
