PROBLEM TO BE SOLVED: To provide a liquid-sealed mount which can display a high damping characteristic in a total frequency region including a low frequency region and an axle box supporter for a railway rolling stock which improves maintainability of a damping device by using this liquid-sealed mount. SOLUTION: In a liquid-sealed mount, a support shaft 4 is inserted to the axial center of a case 1, between an upper end of the support shaft 4 and an upper end of the case 1 is water-tightly sealed by a flexible seal cover 5. Between a lower part of the case 1 and a lower part of the support shaft 4 is water-tightly held by a layered mount 6. A damping plate 8, having between itself and an internal peripheral surface of the case 1 a space 8a to be provided in a water-tight chamber formed by the flexible seal cover 5 and the layered mount 6, is mounted in an upper part of a support shaft 4. A damping plate 9 having between itself and the support shaft 4 a space 9a is mounted in a stepped part 3 in an internal peripheral surface of the case 1, the water-tight chamber is sealed with high viscosity liquid 7. In an axle box supporter for a railway rolling stock, this liquid-sealed mount is utilized as a damping device. |
