Abstract

A slipper bushing assembly including a series of concentric members for permitting controlled sliding movement between a support element and a movable element. The concentric members of the slipper bushing assembly include a rigid one piece inner metal member joined to the support element, a hollow cylindrical elastomeric member, a rigid, one piece hollow outer metal member, a solid slip surface and structure for preventing the inner metal member from disengaging from the outer metal member. The inner metal member has a pair of opposing ends and an outer cylindrical-like surface. The elastomeric member encircles the outer surface of the inner metal member and has a pair of opposing ends, an outer surface and an inner surface. The outer metal member is joined to the movable element and has a pair of opposing ends and an outer cylindrical surface. The slip surface is contiguous to the inner or outer surface of the elastomeric member and coextensive therewith.

Dependent claims

A slipper bushing assembly including a series of concentric members for permitting controlled sliding movement between a support element and a movable element, the slipper bushing assembly comprising;

a) a rigid one piece inner metal member adapted to be joined to the support element, said inner metal member having a pair of opposing ends and an outer cylindrical surface;
b) a hollow cylindrical elastomeric member encircling said outer surface of said inner metal member and having a pair of opposing ends, an outer surface and an inner surface;
c) a rigid, one piece hollow outer metal member adapted to be joined to the movable element, said outer metal member having a pair of opposing ends and an outer cylindrical surface;
d) a solid slip surface contiguous with said elastomeric member and coextensive therewith allowing circumferential movement of said inner metal member with respect to said outer metal member;
and
e) means for preventing said inner metal member from disengaging from said outer metal member;
wherein said solid slip surface includes a split metal annular sleeve having a polymer inner surface, said solid slip surface configured to fit within a groove formed within the outer surface of the inner metal member.
