Title:
VIBRATION DAMPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/021108
Kind Code:
A1
Abstract:
In this vibration damping device (10), a plurality of pressure-receiving liquid chambers (25, 26) are arranged within a first mounting member (12), and one section of the wall surface of said pressure-receiving liquid chambers (25, 26) is configured from an elastic body (14). The pressure-receiving liquid chambers (25, 26) comprise a pair of first pressure-receiving liquid chambers (25) that are connected to each other via a first limiting path (27), and a second pressure-receiving liquid chamber (26) that is connected to an auxiliary liquid chamber (26) via a second limiting path. A second mounting member (13) is sandwiched between the pair of first pressure-receiving liquid chambers (25). The second pressure-receiving liquid chamber (26) is arranged so as to be aligned with the second mounting member (13) in an orthogonal direction (D1) that is orthogonal to both the axial direction of the first mounting member (12) and to a sandwiching direction (D2) that is the direction in which the pair of first pressure-receiving liquid chambers (25) sandwich the second mounting member (13). The second mounting member (13) extends along the entire length of the axial directions of each of the pair of first pressure-receiving liquid chambers (25) and of the second pressure-receiving liquid chamber (26). The first limiting path (27) is arranged so as to be apart from the auxiliary liquid chamber (28). This vibration damping device (10) is capable of making it easier to maintain the performance of the elastic body (14) over a long period of time.
