摘要： 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 when the amplitude of vibration is large, and capable of preventing the occurrence of lateral vibration. Accordingly, a case (11) and a guide shaft (14) are joined to each other with cylindrical mount rubber (17), and a high attenuation liquid (21) is sealed in a liquid sealing chamber (20) fixed to a lower end of the case (11), a damper plate (23) being held on a lower end of the guide shaft (14). An elastic member (24) which is deformed finely by a &cir& _ due to the resistance of the high attenuation liquid (21) when vertical vibration occurs is fixed to the upper and lower surfaces of the damper plate (23). When intermediate and high frequency vibration the amplitude of which is not more than +/-a occurs, the elastic member (24) is deformed and not attenuated, and a vibration isolating action occurs owing to the mount rubber (17). When low frequency vibration the amplitude of which is in excess of +/-a occurs, the damper plate (23) and elastic member (24) are moved unitarily, and an attenuation force occurs.

摘要： A liquid-filled suspension which connects one of separate members to the other and comprises a cylindrical-shaped mount rubber (43) secured to the one of the separate members and having the other of the separate members axially slidably fitted thereonto, said mount rubber (43) being formed by laminating a plurality of rubber layers (46a, 46b, 46c), which are different in at least one of radial thickness and axial height, with a plurality of cylindrical-shaped members (45a, 45b, 45c) therebetween, and a spring member (57) interposed between a damper plate (50) and the inner bottom surface of a container (40) and comprising a coil spring. With such arrangement, a large stroke in an axial direction is obtained and vibration isolation and preventing of rolling due to vibration are both ensured in a lateral direction.
