NOISE REDUCTION DAMPER OF VEHICLE WHEEL

A damper for reducing the running noise of wheels of rail vehicle is disclosed. The damper comprises a damping connector and a damping ring (11) having an open section (12), which has an inclined surface at both ends thereof, respectively. The damping connector comprises a tubular body (1), at both ends of which a locator (2) is provided, respectively, wherein the locator (2) comprises a cylindrical part (3), which is insertable into one end of the tubular body (1), and a wedge-shaped part (4), which comprises an inclined plane cooperating with the inclined surface at the end of the open section of the damping ring (11). A spring (5) is arranged inside the tubular body (1), which pushes outwards the locators (2) at both ends of the tubular body (1). The locator (2) comprises a locating hole (6), into which a locating pin (7) is insertable through the tubular body (1). The damper ensures effective connection between the damping connector and the ends of the open section of the damping ring, and further effectively absorbs vibration of the wheels, reduces modal oscillation amplitude and noise radiation of the wheels.
