A damper for reducing the running noise of vehicle wheels on tracks, comprising a damping connector and a damping ring (11); the damping ring (11) has an open section (12); the end of the open section (12) has a bevel; the damping connector has a tubular body (1); each of two ends of the tubular body (1) has a locator (2); the locators (2) comprise a cylindrical body (3) part and a wedge-shaped body (4) part; the cylindrical body (3) can be inserted into the end of the tubular body (1); the inclined surface of the wedge-shaped body (4) matches the bevel of the open section of the damping ring (11); the tubular body (1) is provided with a spring (5) therein for pushing the locators (2) of the two ends outward; and the locators (2) each have a positioning hole (6), and a positioning pin (7) can be inserted into the positioning hole (6) through the tubular body (1). The damper ensures effective connection between the damping connector and the end of the open section of the damping ring, ensures that the damping ring can effectively absorb the vibration of vehicle wheels, decreases the modal amplitude of the vehicle wheels, and reduces noise radiation of the vehicle wheels.
