Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
124 words
A wheel for carrying continuous track of a crawler type vehicle, comprising: a hub member; a rim; first and second spaced inner panels connecting the hub to the rim; first and second outer panels each spaced from a respective inner panel, one of said pair of inner panels and said pair of outer panels being a laminate formed of at least first and second different materials; means for connecting the outer panels to the inner panels at locations immediately adjacent only the hub; a pair of first vibration damping elements, each element being positioned between respective inner and outer panels adjacent the hub; and a pair of second vibration damping elements, each element being positioned between respective inner and outer panels adjacent the rim.
Claim 2
Dependent Claim
124 words
A wheel for carrying continuous track of a crawler type vehicle, comprising: a hub member; a rim; first and second spaced inner panels connecting the hub to the rim; first and second outer panels each spaced from a respective inner panel, one of said pair of inner panels and said pair of outer panels being a laminate formed of at least first and second different materials; means for connecting the outer panels to the inner panels at locations immediately adjacent only the hub; a pair of first vibration damping elements, each element being positioned between respective inner and outer panels adjacent the hub; and a pair of second vibration damping elements, each element being positioned between respective inner and outer panels adjacent the rim.
Claim 3
Dependent Claim
31 words
Apparatus, as set forth in claim 1, wherein the first material of the laminate is steel and the second material is a viscoelastic material substantially covering first surfaces of the panels.
Claim 4
Dependent Claim
47 words
Apparatus, as set forth in claim 1, including a third material forming the laminate and wherein the first material of the laminate is steel, the second material is a viscoelastic material substantially covering first surfaces of the panels, and the third material substantially covers the viscoelastic material.
Claim 5
Dependent Claim
21 words
Apparatus, as set forth in claim 3, including means for maintaining the materials of the laminate fixed one to the others.
Claim 6
Dependent Claim
37 words
Apparatus, as set forth in claim 1, wherein the means connecting the outer panels to the inner panels each comprises a threaded fastening member and viscoelastic material positioned between the threaded fastening member and the inner panels.
Claim 7
Dependent Claim
117 words
A wheel for carrying continuous track of a crawler type vehicle, comprising: a hub member; a rim; first and second spaced inner panels connecting the hub to the rim; first and second outer panels each spaced outwardly from a respective inner panel and being of a laminate formed of at least first and second different materials; means for connecting the outer panels to the hub; means for connecting the outer panels to the inner panels at locations immediately adjacent the rim; and connecting means for damping vibrations and connecting middle portions of the outer panels to middle portions of respective inner panels, said vibration damping connecting means forming a viscoelastic barrier between respective inner and outer panels.
Claim 8
Dependent Claim
117 words
A wheel for carrying continuous track of a crawler type vehicle, comprising: a hub member; a rim; first and second spaced inner panels connecting the hub to the rim; first and second outer panels each spaced outwardly from a respective inner panel and being of a laminate formed of at least first and second different materials; means for connecting the outer panels to the hub; means for connecting the outer panels to the inner panels at locations immediately adjacent the rim; and connecting means for damping vibrations and connecting middle portions of the outer panels to middle portions of respective inner panels, said vibration damping connecting means forming a viscoelastic barrier between respective inner and outer panels.
Claim 9
Dependent Claim
57 words
Apparatus, as set forth in claim 6, wherein said connecting means comprises: a female member having an opening and being fixedly connected to an inner panel; a threaded member extending through a respective outer panel and into the female member opening; and viscoelastic material positioned in the opening and between the female member and the threaded member.
Claim 10
Dependent Claim
31 words
Apparatus, as set forth in claim 6, wherein there are a plurality of connecting means, one portion of said connecting means being radially spaced from another portion of said connecting means.
