Tyre noise reducing system

摘要

A tyre noise reducing system comprises a wheel rim (3a), a pneumatic tyre (1) to be mounted on the wheel rim (3a) to form an annular tyre hollow (4), and a resonance damper (6) to be disposed in the annular tyre hollow (4), wherein the damper (6) is one of an annular elastic loose band disposed around the rim and a flexible slack strip having a certain length and fixed to the wheel rim at two points so that a portion between the fixed points slacks, whereby a loose portion of the loose band and the slack portion of the slack strip are risen by a centrifugal force during running to block the annular tyre hollow.
