VIBRATION ISOLATION BUSH FOR VEHICLE SUSPENSION USING MULTI-LAYER COIL SRRUCTURED CORE MEMBER AND MAGNETO-RHEOLOGICAL ELASTOMER

摘要

The present invention relates to a vibration isolation bush installed on a suspension module of a vehicle chassis, which comprises a vibration insulator consisting of a core member on which a wire coil is wound in at least two places and a magnetorheological elastic body surrounding the surface of the core member; and a housing for protecting the combination of the core member and the vibration insulator. Therefore, vibration isolation performance is maintained when a magnetic field is not applied through switching of an operator operation mode, and the steering stability of a vehicle is improved by changing the stiffness of the magnetorheological elastic body according to the strength of the magnetic field when a magnetic field is applied.
