Abstract
Official abstract text for this publication.
According to the present invention, there is provided a slide member for a shock absorber of a vehicle including a back metal, a porous sintered metal layer containing a porous sintered metal formed on the back metal and a resin with which the porous sintered metal is impregnated and covered, and a resin slide layer formed on the porous sintered metal layer and having a smooth slide surface, and the slide member is formed in a cylindrical shape so that the resin slide layer is disposed on an inner peripheral side. The resin slide layer is composed of polytetrafluoroethylene and a plurality of granular elements dispersed in the polytetrafluoroethylene, and the granular element is composed of molybdenum disulfide and molybdenum trioxide, and/or tungsten disulfide and tungsten trioxide.
First claim
Opening claim text (preview).
1 . A slide member for a shock absorber provided between a vehicle body and a wheel of a vehicle for supporting a piston rod reciprocally sliding in an axial direction in the shock absorber, comprising: a back metal; a porous sintered metal layer containing a porous sintered metal formed on the back metal and a resin with which the porous sintered metal is impregnated and covered; and a resin slide layer formed on the porous sintered metal layer and having a smooth slide surface, wherein the slide member is formed in a cylindrical shape so that the resin slide layer is disposed on an inner peripheral side, and the resin slide layer contains polytetrafluoroethylene and a plurality of granular elements dispersed in the polytetrafluoroethylene, and each granular element is composed of molybdenum disulfide and molybdenum trioxide, and/or tungsten disulfide and tungsten trioxide. 2 . The slide member according to claim 1 , wherein a surface roughness of the slide surface of the resin slide layer is equal to or less than 5 μm in ten-point average roughness (Rz). 3 . The slide member according to claim 1 , wherein an average particle diameter of the plurality of granular elements is 5 to 25 μm, and a content amount of the plurality of granular elements in the resin slide layer is 5 to 30 vol. %. 4 . The slide member according to claim 1 , wherein a content amount of the molybdenum trioxide and/or the tungsten trioxide in the granular elements is 20 to 50 vol. %. 5 . The slide member according to claim 1 , wherein the resin slide layer further contains carbon and/or graphite of 5 vol. % or less in total.
