Abstract
A resilient bushing having an inner sleeve, an outer sleeve disposed around the inner sleeve in co-axial and radially-spaced relation thereto, and a cylindrical resilient member interposed between the inner and outer sleeves. The bushing comprises an intermediate sleeve substantially embedded in the cylindrical resilient member in co-axial relation thereto. The intermediate sleeve has a radially outward flange at one or both of its axial ends.
Claims6
A resilient bushing having an inner sleeve, an outer sleeve disposed around the inner sleeve in co-axial and radially-spaced relation thereto, and a cylindrical resilient member interposed between the inner and outer sleeves, comprising:
- an intermediate sleeve substantially embedded in said cylindrical resilient member in co-axial relation thereto, said intermediate sleeve having a first outward flange at one of its opposite axial ends and a second outward flange at its other axial end, said first outward flange extending radially outwardly of the intermediate sleeve by a distance which is greater than that of said second outward flange,
- said resilient member having a ring portion which extends radially outwardly from an axial end thereof, said ring portion adhering to one of opposite surfaces of said first outward flange of the intermediate sleeve which faces said second outward flange, a width of said ring portion as measured axially of the resilient member, before said outer sleeve is press-fitted on said inner assembly unit, being larger at a radially outer part thereof than at a radially inner part thereof,
- said inner sleeve, said intermediate sleeve and said resilient member being formed as an integral inner assembly unit, through vulcanization of a fluidized rubber material in a mold,
- said outer sleeve being press-fitted on said inner assembly unit and having, at one of opposite axial ends thereof, an outward flange which extends radially outwardly of the outer sleeve, said outward flange of the outer sleeve being held in pressed contact with said ring portion of the resilient member.
