LIQUID SEALED MOUNT

摘要

PROBLEM TO BE SOLVED: To prevent the occurrence of hammering due to the collision of an elastic partition wall 52 deflected with a liquid pressure change in a first liquid chamber 6 with a displacement restricting portion of a partition wall 5 or breakage due to the excessive deformation of the elastic partition wall 52. SOLUTION: A liquid sealed space between an elastic body 3 connecting a first mounting member 1 to a second mounting member 2 and a driven body 4 sealingly provided on the inner periphery of the first mounting member 1 is partitioned into the first liquid chamber 6 on the side of the elastic body 3 and a second liquid chamber 7 on the side of the driven body 4 with the partition wall 5. The first and second liquid chambers 6, 7 are communicated with each other via orifices 8U, 8L. The partition wall 5 consists of a rigid partition wall 51 fixed to the first mounting member 1 and the elastic partition wall 52 provided in the condition of closing an opening portion 51a of the rigid partition wall 51. The elastic partition wall 52 is swollen into a protruded shape toward the first liquid chamber 6 to undergo compression with the pressure of the first liquid chamber 6, and its inner peripheral portion 52a is formed thicker than an outer peripheral portion.
