RAILROAD ROLLING STOCK CARRIAGES Russian patent published in 2008 - IPC B61F5/22 B61F5/02 

FIELD: transport.

SUBSTANCE: rolling stock carriage incorporates wheels or wheel pairs supporting, via a primary spring suspension system, frame (1) which, in its turn, supports, not necessarily via intermediate swinging scaffold (4), car body (5). The said swinging scaffold or the car body leans relative to the frame against spring beam (2) via springs (6) of the secondary suspension system. The swinging scaffold or the body is jointed to the frame by means of shock-absorbers cushions vertical vibrations and/or rolling. The spring beam is suspended to the frame by means of pendulum-type suspensions. Note here that the points of attachment of the said suspensions to the frame are shifted towards the centre of the latter that makes the pendulum suspension lengthwise axes located inclined. Active actuator (7) is arranged horizontally between the frame and the spring beam to add to the centrifugal force effect, thus, to ensure the car inclination at an optimum angle.

EFFECT: higher speeds at curvilinear section, higher comfort for passengers, good chances of updating rolling stock carriages.
