FIELD: transport.
SUBSTANCE: invention relates to current collectors of vehicles. The vehicle current-collecting device consists of current collectors located along the length of the vehicle. The current collectors have contact pressure control units interconnected by time delay elements connected to the vehicle speed sensor. In this case, the power electrical circuit of each current collector is equipped with a contactor, the control circuit of which is connected to the locomotive driver's control panel, and the contactor of the first current collector as viewed in the direction of vehicle motion is made normally open. In this case, the first current collector as viewed in the direction of vehicle motion has a unit for lubricating the contact wire with an electrically conductive lubricant with a feed regulator, the input of which is connected to the output of the vehicle speed sensor .
EFFECT: invention is aimed at improving the quality of current collection.
