FIELD: railway transport; bolster and axle-box suspension of freight car bogies. SUBSTANCE: friction vibration damper has pressure cone, expanding wedges moving inside cup and outer spring installed on cup flange. Load from pressure cone onto expanding wedge is transmitted through carriers (not directly), carriers being hinge connected with pressure cone and expanding wedges. Point of load application on expanding wedge is located in the middle of friction (contacting) surfaces. EFFECT: provision of constant parameters of vibration damper, enhanced stability of damper operation. 1 dwg
