  "title": "Elastic bearing for motor suspension of motor vehicles",
  "abstract": "An elastic bearing for the motor suspension in motor vehicles having an inner sleeve and a radially spaced outer sleeve with a preloaded rubber body therebetween, in which said outer sleeve has a radially extending flange engaged by a first bead portion of said rubber body which first portion tapers away from said flange, said rubber body also having a second tapered portion adjacent said first tapered portion and tapering to a greater extent than said first tapered portion but tapering in the same direction as the latter.",
  "claims": [
    "1. An elastic bearing for the suspension of a motor in a motor vehicle, which includes: an inner, substantially vertical, metallic sleeve, a disc fixed on the upper end of said inner sleeve, an outer metallic sleeve substantially coaxial with said inner metallic sleeve and surrounding the latter in axially spaced relationship thereto, said outer sleeve being axially considerably shorter than said inner sleeve and having a radially outwardly extending abutment at each end, a body of rubber between said inner and outer sleeves, said body having an internal diameter less than the diameter of said inner sleeve and a circumferential channel with radial end walls intermediate its ends to receive said outer sleeve with said abutments in engagement with said walls, said channel normally being of less width than the length of said outer sleeve to expand the width of said channel by said outer sleeve, said body being normally of greater thickness than the distance between said sleeves, so that said body is under compression in a radial direction between said sleeves by the expanding force of said inner sleeve and the compression force of said outer sleeve and is under stress in an axial direction between said upper radial abutment and said disc, the radial thickness of said rubber body between said outer and inner sleeves being at least as great as the axial length of said outer sleeve, said rubber body being formed with upper and lower bead means at the opposite ends of said outer sleeve, said lower bead means tapering downwardly away from said outer sleeve, said upper bead means being substantially longer axially than the axial width of said channel and substantially thicker radially than said lower bead means with the upper wall of said channel substantially wider radially than the lower wall, the lower portion of said upper bead means normally being of substantially uniform diameter before assembly under said axial stress, and the upper portion normally tapering upwardly to a substantially reduced radial thickness to be engaged and stressed by said disc for supporting the motor on said upper bead means.",
    "2. An elastic bearing for the suspension of a motor in a motor vehicle, according to claim 1, in which said body of rubber has combined triple radial-axial preloading including one force directly radially between said inner and outer metallic sleeves, a second force inclined inwardly in one axial direction of said inner metallic sleeve, and a third force also inclined inwardly in an opposite axial direction of said inner metallic sleeve, all three of said forces being simultaneously effective resiliently to avoid axial sliding of said inner metallic sleeve relative to said body of rubber unhardened during dynamic loading thereon regardless of preloading radially and axially in opposite directions."
