Abstract
A split taper bushing assembly includes a bearing member, an inner sleeve received in a hollow center defined by the bearing and an optional outer sleeve which receives the bearing member in an open center defined therein. The bearing member also includes a tapered skirt. The skirt includes a slit which permits the bearing member to contract during assembly to account for variances in its dimensional tolerances, thus ensuring a proper fit between the bearing member and any mating part. The bearing member is formed using a polyurethane type material. Since such a material resists deterioration due to contact with lubricants commonly used in the automotive industry, the bushing assembly can be relubricated during operation without any destructive affect on the bearing member.
Claims19
A bushing assembly comprising:
- a bearing member comprising a skirt having tapered sidewalls defining a hollow center and a circumferential flange supported by the outer periphery of the upper end of the skirt, the skirt defining a slit therein for adjusting the dimensional tolerances of the bearing member;
- and
- an inner sleeve comprising a cylindrical body and an annular flange projecting from the outer periphery of the cylindrical body, thc cylindrical body being received in the hollow center and the annular flange carried by the circumferential flange.
A bushing for vehicular idler arms comprising:
- a vehicular idler arm defining a central bore at one end of the arm;
- a bushing subassembly received in opposite sides of the bore, the subassembly comprising
- a bearing member comprising a skirt having tapered sidewalls defining a hollow center and a circumferential flange supported by the outer periphery of the upper end of the skirt, the skirt defining a slit therein for adjusting the dimensional tolerances of the bearing member;
- and
- an inner sleeve comprising a cylindrical body and an annular flange projecting from the cylindrical body, the cylindrical body being received in the hollow center and the annular flange being carried by the circumferential flange.
A bushing assembly comprising:
- a bearing member having a skirt with tapered sidewalls defining a hollow center and a circumferential flange supported by the outer periphery of the upper end of the skirt, the skirt defining a slit therein for adjusting the dimensional tolerances of the bearing member, the slit extending along the longitudinal extent of the skirt and into the adjacent surface of the circumferential flange;
- an inner sleeve having a cylindrical body and an annular flange projecting from the outer periphery of the cylindrical body, the cylindrical body frictionally engaging the hollow center of the bearing member and the annular flange resting on the circumferential flange;
- and
- an outer sleeve having tapered sidewalls defining an open center which receives the outer periphery of the skirt and an annular flange extending from the outer periphery of the sleeve and supporting the circumferential flange.
