RAILWAY CAR BODY TILT SYSTEM Russian patent published in 2013 - IPC B61F5/22 

FIELD: transport.

SUBSTANCE: invention relates to railway transport. Proposed system comprises wheels or mounted axles fitted on bogie frame with bolster supporting car body and suspended via system of springs to bogie frame to allow displacement relative to bogie frame with the help of suspensions. Points of attachment of suspensions to bogie frame are shifted inward to bogie centre. Points of attachment of suspensions to bolster are shifted outward to locate lengthwise axes of suspensions inclined and engage them with said bolster at an angle relative to bogie vertical axis. Said suspensions are composed of hydraulic cylinders with rods secured to bogie frame sidewalls to increase vertical and horizontal components of force applied by said cylinders to bolster in direction of car centrifugal force in running on curved track sections, and to decrease said components on bolster opposite side, as well as to make additional turn of bolster, body and car.

EFFECT: simplified design, higher reliability, efficiency and safety.
