FIELD: railway transport. SUBSTANCE: proposed pantograph current collector of electric train has contact device built around asymmetrical single-arm circuit with lower and upper frames, carriage and control unit. Control unit includes drive installed on fixed frame secured on roof of electric train car. According to invention, drive is furnished with torsion bar mechanically coupled with drive. Said torsion bar is provided with contact pressure adjusting unit made in form of worm drive being installed so that longitudinal axis of torsion bar housing is parallel to axis of rotation of lower frame of movable contact device. EFFECT: improved static and dynamic characteristics, increased service life. 4 cl, 3 dwg
