Abstract

This invention relates to a liquid sealed rubber mount capable of displaying an excellent vibration isolating effect in intermediate and high frequency ranges, having a vibration isolating effect with no resonation occurring with respect to even the impact vibration of a wide frequency band, capable of obtaining a large attenuation force for large amplitude vibration, and capable of preventing the occurrence of lateral vibration. Accordingly, a case (11, 51) and a guide shaft (14) are joined to each other by a cylindrical rubber mounting element (17, 58), and a high attenuation liquid (21, 59) is sealed in a liquid sealing chamber housing (20, 53) fixed to a lower end of the case (11, 51), a damper plate (23, 28, 55) being held on a lower end of the guide shaft (14). An elastic member (24, 26, 34, 35, 36a, 36b, 39, 56), which is deformed finely by the distance a due to the resistance of the high attenuation liquid (21, 59) when vertical vibration occurs, is fixed the damper plate (23, 28, 55). When intermediate and high frequency vibration, the amplitude of which is not more than .+-.a, occurs, the elastic member (24, 26, 34, 35, 36a, 36b, 39, 56) is deformed and is not attenuated, and a vibration isolating action occurs owing to the rubber mounting element (17, 58). When low frequency vibration, the amplitude of which is in excess of .+-.a, occurs, the damper plate (23, 28, 55) and elastic member (24, 26, 34, 35, 36a, 36b, 39, 56) are moved unitarily, and an attenuation force occurs. The cylindrical rubber mounting element (58) can be a cylindrically laminated structure provided with one or more cylindrical laminate plates (57) positioned therein.
