Pivot or support sleeve with resilient layer

Claim 1

A resilient bushing, comprising: a relatively massive cylindrical metallic inner member defining an axis; a relatively thin sheet-metal outer member comprising a pair of half shells centered on said axis and separated from one another by a peripheral gap; a respective layer of elastomeric material bonded to each of said half shells and to said inner member; and an intermediate thin sheet-metal member comprising a pair of half shells peripherally spaced apart along said gap and intermediate said outer and inner members while being bonded to the respective layer, the half shells of said intermediate member being centered on said axis whereby radial compression of said outer and inner members forces the half shells thereof into contiguous relation to produce closed sleeves coaxial with one another and centered on said axis, the bushing being formed with a pair of outwardly diverging V-profile grooves extending longitudinally along said members and defining said gaps, each said layer comprising an elastomeric body between the half shells of the outer and intermediate members and an elastomeric body between each intermediate half shell and said inner member, said intermediate half shells being provided with perforations filled with the elastomeric material of said bodies.
