A frictional vibration dampener of a freight car bogie consists of two symmetrical wedges pressed by car weight by its vertical surfaces against friction strips of a side frame, and by inclined surfaces - against bolster pockets. The friction strips of the side frame are parallel, a friction wedge consists of two mirrored parts which inclined surfaces have the length b, form an angle α to the horizontal and are turned to each other at an angle &bgr;. |
