Document Type and Number:
WIPO Patent Application WO/2018/181051
Kind Code:
A1
Abstract:
[Problem] To enhance standardization of components and increase the degree of freedom in designing by enabling coping with a plurality of vibration characteristics with a minimum necessary number of changes. [Solution] A railway vehicle rubber bushing 1 includes: an axial member 2; an outer cylindrical member 3 that is coaxially arranged outside the axial member 2; and a rubber elastic body 4 that elastically links the axial member 2 and the outer cylindrical member 3, wherein the rubber elastic body 4 has, at point-symmetrical positions with the axial member 2 being the center, liquid chambers 9, 9 in each of which a liquid is sealed. The axial member 2 has a core member 6 that is provided with a through-hole 11 for connecting the liquid chambers 9, 9 with each other and that is fitted in the axial member 2, and a flow path member 12 is separately provided in the through-hole 11 of the core member 6.
