LIQUID-SEALED VIBRATION CONTROL EQUIPMENT

摘要

A partitioning member 40 partitioning two liquid chambers 36A, 36B includes an orifice forming member 44, an elastic wall 46 configured to close an inner peripheral surface 44A thereof, and a pair of partitioning plates 48 and 50 which hold the elastic wall from both sides in an axial direction X. The pair of partitioning plates includes a holding portion 60 configured to hold the elastic wall 46 radially outward Ko of a coupling portion 56. The holding portion comprises a first holding portion 64 on the radially outside and a second holding portion 66 on the radially inside, and the first holding portion 64 is provided with a high-compression holding portion 68 having a compression ratio higher than that of the second holding portion 66. Accordingly, the abnormal sound is reduced while achieving both the damping performance in the low frequency range and the lowering of the dynamic spring constant in the high-frequency range without impairing the assembleability of the partitioning member.
