LIQUID SEALING VIBRATION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a liquid sealing vibration control device difficult to lower vibration control performance, even in a driving state having the number of vibration of a vibrator exceeding the range of the number of vibration of the vibrator at a normal driving time. SOLUTION: A first mounting tool 1 and a second cylindrical mounting tool 2 are connected via a vibration control base body 3 made of a rubber-like elastic material. The second mounting tool 2 is provided with a diaphragm 5 for forming a liquid chamber 4 between the second mounting tool 2 and the vibration control base body 3. A partition part 8 is provided to partition the liquid chamber 4 into a first liquid chamber part 6 and a second liquid chamber part 7. An orifice 22 is formed to communicate the first liquid chamber part 6 and the second liquid chamber part 7. A part 10 to be stopped to be extended to a radial direction outside of the second mounting tool 2 is formed on the second mounting tool 2 side. A stopper member 11 to receive the part 10 to be stopped in an axialcenter direction of the second mounting tool 2 is provided on the first mounting tool 1 side. The stopper member 11 is provided with a dynamic damper16 or a mass damper 40. COPYRIGHT: (C)2004,JPO
