FIELD: transportation.
SUBSTANCE: invention relates to railway transport, particularly, to friction dampers for railway car bogies. Replaceable friction linings are arranged on inclined and horizontal surfaces of the friction wedge. Lining on the vertical surface is made with a metal frame and is connected to the wedge by a dovetail joint. Lining is fixed in the connection by the bent retainers. Lining on the vertical surface is made of a polymer friction composite with a steel friction coefficient of 0.30–0.40. Lining on the inclined surface is made of vulkollan with steel friction coefficient of 0.2–0.25.
EFFECT: higher reliability of attachment of vertical lining.
