FIELD: transport engineering. SUBSTANCE: invention relates to current collectors of electric vehicles and it is designed for stabilization of contact pressure at high running speeds and reduction of drag owing to limiting action of aerodynamic forces onto current collector. Proposed device creates vortex layer around pan of current collector which blows off oncoming air stream and suspended particles. EFFECT: reduced intensity of stream acting onto pan and concentration of suspended particles in zone contact. 1 dwg
