PROBLEM TO BE SOLVED: To provide a liquid sealed type rubber mount for vibration control which has vibration control ability in intermediate and high frequency ranges, does not induce resonance for impact vibration in a wide frequency range, and reduces rolling. SOLUTION: A liquid sealed chamber 20 is fixed to one end of a case 11 of a mount to accommodate a damper plate 22. It is connected with cushion rubber 28 narrowly grabbing guide-shaft-shaped laminate plates 29 having a bolt 27 connected with the damper plate 22. The cushion rubber 28 is decreased in spring constant with hardness Hs of 45 deg.-60 deg.. High damping liquid of 50,000-150,000 cSt is filled into the liquid sealed chamber 20. Vibration control of vertical vibration is excellent at intermediate and high frequencies because the spring constant is low, resonance is not induced even for impact vibration thanks to high damping liquid, cylindrical laminate shape of the cushion rubber 28 increases horizontal spring constant, and therefore, rolling is reduced. |
