The invention provides a suspension arm bush capable of selectively improving vibration noise performance and riding comfort performance. A suspension arm bush (1) is provided with coils (31, 32). The first magnetorheological elastic bodies (21) are provided on both sides of the cylinder (13) in the axial direction so as to sandwich the coils (31, 32). The second magnetorheological elastic body (22) is provided in the cylindrical body (13) so as to be sandwiched by the coils (31, 32). The control unit (42) selectively switches the magnetic fields generated by the coils (31, 32) to the same direction or the opposite direction.
本发明提供能够选择性地实现振动噪音性能提高及乘坐舒适性能提高的悬架臂衬套。悬架臂衬套(1)具备线圈(31、32)。第1磁流变弹性体(21)以将线圈(31、32)夹入的方式分别设置在筒体(13)的轴向两侧。第2磁流变弹性体(22)以被线圈(31、32)夹入的方式设置于所述筒体(13)。控制部(42)将线圈(31、32)产生的磁场选择性地切换为相同方向或相反方向。
