Title:
VIBRATION-PROOFING DEVICE
Document Type and Number:
Japanese Patent JP2018112248
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vibration-proofing device which can damp and absorb vibration in an axial direction and a lateral direction.SOLUTION: A vibration-proofing device includes: an outer attachment member 11; an inner attachment member 12; a pair of first body rubbers 13 connecting the outer attachment member 11 with the inner attachment member 12; a partition member 16 which partitions a liquid chamber 30 between the first body rubbers 13 into a first liquid chamber 31 and a second liquid chamber 32; and elastic division members which individually divide the first liquid chamber 31 and the second liquid chamber 32 in a circumferential direction to define two first divided liquid chambers 31A, 31B and second divided liquid chambers 32A, 32B. The elastic division members are disposed on the same straight line. The partition member 16 is formed with a first restriction passage 51A and a second restriction passage 51B which individually allow communication between the pair of first divided liquid chambers 31A, 31B and the pair of second divided liquid chambers 32A, 32B. Each of these restriction passages 51A, 51B allows communication between the divided liquid chamber of the first divided liquid chambers and the divided liquid chamber of the second divided liquid chambers which are located at different positions in the circumferential direction.SELECTED DRAWING: Figure 1
