VIBRATION-DAMPING DEVICE

摘要

The present invention is a vibration-damping device (10, 60, 80) which is provided with: a first attachment member (11) joined to one of a vibration generating unit and a vibration receiving unit and a second attachment member (12) joined to an other thereof; an elastic body which joins the first attachment member (11) to the second attachment member (12); a partition member (16, 90) which partitions a liquid chamber in the first attachment member (11) into a first liquid chamber (14) and a second liquid chamber (15), and in which at least one of the first liquid chamber (14) and the second liquid chamber (15) has the elastic body (13) as a portion of a wall surface thereof. The partition member (16, 90) is provided with a communicating passage (30), and the communicating path (30) is provided with a branching section (33) and a confluence section (32, 70, 84, 101).

主权项

1. A vibration-damping device in which at least one of a first liquid chamber and a second liquid chamber has an elastic body as a portion of a wall surface, the vibration-damping device comprising:
a tubular first attachment member joined to one of a vibration generating unit and a vibration receiving unit; a second attachment member joined to an other of the vibration generating unit and the vibration receiving unit; an elastic body which joins the first attachment member to the second attachment member; and a partition member which partitions a liquid chamber in the first attachment member in which a liquid is sealed into a first liquid chamber and a second liquid chamber, wherein the partition member is provided with a communicating passage through which the first liquid chamber communicates with the second liquid chamber, and the communicating passage is provided with a branching section which branches a flow of the liquid flowing between the first liquid chamber and the second liquid chamber via the communicating passage and a confluence section which joins at least a portion of flows of the liquid which is branched by the branching section to a flow of another portion of the liquid flowing in the communicating passage.
