FIELD: electricity; transportation.
SUBSTANCE: group of inventions relates to current collectors of vehicles. Device for control of clamping force of vehicle current collector to contact wire includes main control circuit and additional control circuit. At that, clamping force is initiated by working pressure pneumatically or hydraulically. Main control circuit has main control circuit regulating device intended for main pressure control from provided produced pressure. Additional control circuit comprises control device designed to control additional pressure from produced pressure. Note here that main pressure and additional pressure are combined at connection point to feed working pressure to working pressure control circuit. Also disclosed are versions of a method of controlling clamping force of a current collector of a vehicle to a contact wire, as well as a vehicle with at least one device for controlling clamping force of current collector.
EFFECT: technical result consists in more accurate control of required pressing forces between current collector and contact wire.
