Abstract
Abstract A resilient bearing having an inner and an outer tubular member with a rubber bushing compressed therebetween. The rubber bushing has ribbed areas to permanently retain a lubricant. The outer member which faces the ribbed surface is encapsulated by a plastic liner which is shrunk in situ on the outer member to provide mechanical locking and a tight seal.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
124 words
A resilient bearing, for rotary motion, particularly for vehicle suspension systems, comprising in combination: a rigid tubular inner member and a rigid tubular outer member concentrically disposed about the inner member; a loadtransmitting rubberlike bushing compressed between said members, one circumferential surface of the bushing being secured to the outside surface of the inner member and the other circumferential surface having lubricant retaining grooves facing the outer member; a molded layer of plastic material shrunk in situ encapsulating the inner circumferential surface of the outer tubular member and having a nonuniform thickness formed on a portion of the outer surface of said outer member with a nonuniform thickness, said layer facing said lubricant-retaining grooves and also encapsulating the axial ends of the outer member.
Claim 2
Dependent Claim
124 words
A resilient bearing, for rotary motion, particularly for vehicle suspension systems, comprising in combination: a rigid tubular inner member and a rigid tubular outer member concentrically disposed about the inner member; a loadtransmitting rubberlike bushing compressed between said members, one circumferential surface of the bushing being secured to the outside surface of the inner member and the other circumferential surface having lubricant retaining grooves facing the outer member; a molded layer of plastic material shrunk in situ encapsulating the inner circumferential surface of the outer tubular member and having a nonuniform thickness formed on a portion of the outer surface of said outer member with a nonuniform thickness, said layer facing said lubricant-retaining grooves and also encapsulating the axial ends of the outer member.
Claim 3
Dependent Claim
62 words
A resilient bearing according to claim 1, wherein one axial end of the outer member is circumferentially recessed on the outer circumferential surface and said nonuniform layer is imposed upon the recessed area to establish an outer surface in which the outside diameter of the major portion of the outer member is the same as the corresponding Diameter of the plastic layer.
Claim 4
Dependent Claim
25 words
A resilient bearing according to claim 1, wherein one axial end of the outer member is radially flanged and said encapsulation extends around the flange.
Claim 5
Dependent Claim
32 words
A resilient bearing according to claim 1, wherein said outer member is provided with mechanical retaining notches, and said plastic layer fills the notches to prevent relative rotary movement between the parts.
Claim 6
Dependent Claim
30 words
A resilient bearing according to claim 4, wherein said outer member is radially flanged at one axial end and said notches are located in the outer periphery of said flange.
Claim 7
Dependent Claim
26 words
A resilient bearing according to claim 1, wherein the shrinkage in situ is effective to establish a seal between the plastic layer and the outer member.
Claim 8
Dependent Claim
152 words
A resilient bearing, for rotary motion, particularly for vehicle suspension systems, comprising in combination: a rigid tubular inner member and a rigid tubular outer member concentrically disposed about the inner member; a load-transmitting rubberlike bushing compressed between said members, one circumferential surface of the bushing being secured to the outside surface of the inner member and the other circumferential surface having lubricant-retaining grooves facing the outer member; a layer of plastic material shrunk in situ encapsulating the inner circumferential surface of the outer tubular member facing said lubricant-retaining grooves and also encapsulating the axial ends of the outer member; one axial end of the other member being circumferentially recessed on the outer circumferential surface and said layer being imposed upon the recessed area to establish an outer surface in which the outside diameter of the major portion of the outer member is the same as the corresponding diameter of the plastic layer.
Claim 9
Dependent Claim
152 words
A resilient bearing, for rotary motion, particularly for vehicle suspension systems, comprising in combination: a rigid tubular inner member and a rigid tubular outer member concentrically disposed about the inner member; a load-transmitting rubberlike bushing compressed between said members, one circumferential surface of the bushing being secured to the outside surface of the inner member and the other circumferential surface having lubricant-retaining grooves facing the outer member; a layer of plastic material shrunk in situ encapsulating the inner circumferential surface of the outer tubular member facing said lubricant-retaining grooves and also encapsulating the axial ends of the outer member; one axial end of the other member being circumferentially recessed on the outer circumferential surface and said layer being imposed upon the recessed area to establish an outer surface in which the outside diameter of the major portion of the outer member is the same as the corresponding diameter of the plastic layer.
