Abstract: The invention relates to an assembly (1) for a railway vehicle, of the type comprising a first chassis (8) and a second chassis (9) which is connected to the stationary chassis (8) to tilt laterally with respect thereto on each side of a position of rest, the assembly (1) further comprising means (10) for moving the second chassis (9) laterally. The movement means (10) comprise an arm (28) for driving the second chassis (9) laterally, which arm (28) is mounted so that it can pivot about a longitudinal axis (X—X). Application, for example, to a power pick-up assembly for a tilting railway vehicle.

Abstract: This power pick-up for a railway vehicle comprises a pantograph (4) and a pantograph support (7), the pantograph support (7) comprising a stationary chassis (8) for mounting on the roof (2) of a railway vehicle (3), and a mobile chassis (9) carrying the pantograph (4) and connected to the stationary chassis (8) to tilt laterally with respect thereto on each side of a position of rest. The mobile chassis (9) is connected to the stationary chassis (8) by two tilting rigid lateral supports (14), each tilting support (14) being articulated, on the one hand, to the stationary chassis (8) at two longitudinally-spaced points (17) and, on the other hand, to the mobile chassis (9) at two longitudinally-spaced points (22).
