FIELD: electrical engineering.
SUBSTANCE: invention relates to current collectors for power supply lines of transport facilities. Pantograph (5) comprises at least one frame (51), bow (52) and bow suspension mounted between frame (51) and bow (52). Bow suspension comprises at least one pneumatic cylinder (6). Pneumatic cylinder (6) includes a cylinder (7) integral with frame (51) and piston (8) integral with bow (52). Piston (8) is mounted in translation in said cylinder (7) so as to divide volume of cylinder (7) between upper air chamber (61) and lower air chamber (62). Each inflatable chamber (61, 62) comprises a pressurised gas damping movement of piston (8).
EFFECT: technical result consists in improvement of dynamic characteristics of pantograph.
