DAMPING DEVICE AT THE END OF ROLLING STOCK TO COUNTERACT SIDE ROLLING, AS WELL AS RAILWAY ROLLING STOCK AND TRAIN Russian patent published in 2024 - IPC B61F5/24 

FIELD: machine building.

SUBSTANCE: invention relates to rolling stock end damping device for counteracting side rolling and to railway rolling stock. Damping device at the end of rolling stock to counteract side rolling includes: a pair of damping mechanisms, which are adapted for installation on a pair of end walls of a pair of connected bodies of a rolling stock, which are located opposite to each other, respectively, wherein the pair of damping mechanisms is located on two sides of the axle of the rolling stock bodies in the longitudinal direction, respectively; and connecting rod, wherein two ends of connecting rod are pivotally attached to a pair of damping mechanisms, respectively, and the length of the connecting rod is greater than the displacement of the vertical movement of any rolling stock body, so that side rolling movement and vertical movement of rolling stock body are separated. By means of a damping device at the end of the rolling stock to counteract side rolling, it can be ensured that the length of the connecting rod connected between the pair of rolling stock bodies can be much greater than the vertical displacement of each rolling stock body, so that movement of damping mechanisms can be limited by means of connecting rod during different processes of rolling stock body movement, that thereby at least provides separation between movement in form of side rolling and vertical movement of rolling stock body.

EFFECT: as a result, vibration from side rolling can be suppressed more reliably without affecting vertical stability, and stability during movement and comfort during movement of railway rolling stock are significantly improved.
