Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
101 words
A combined radial and axial bearing device for supporting a shaft comprising: (a) a radial bearing composed of a radial bearing ring containing first and second stop means disposed on the terminal portions thereof and rolling elements disposed between said stop means; and, (b) an axial bearing composed of an L-section annulus having a radial flange portion thereof as a thrust plate and an axially extending portion of said thrust plate coaxially nested within one end portion of said bearing ring, having additional stop means on its terminal portion and axially movable between said rolling elements and said first stop means.
Claim 2
Dependent Claim
101 words
A combined radial and axial bearing device for supporting a shaft comprising: (a) a radial bearing composed of a radial bearing ring containing first and second stop means disposed on the terminal portions thereof and rolling elements disposed between said stop means; and, (b) an axial bearing composed of an L-section annulus having a radial flange portion thereof as a thrust plate and an axially extending portion of said thrust plate coaxially nested within one end portion of said bearing ring, having additional stop means on its terminal portion and axially movable between said rolling elements and said first stop means.
Claim 3
Dependent Claim
47 words
A device as set forth in claim 1 wherein said first and second stop means are radial flanges on said radial bearing ring, said rolling elements are disposed and encaged there between, and said thrust plate is axially movable between said cage and said first stop means.
Claim 4
Dependent Claim
23 words
A device as set forth in claim 2, including an annular separating member disposed between the said first and said second stop means.
Claim 5
Dependent Claim
38 words
A device as set forth in claim 3, including an elastomeric cushion spaced apart from the radial flange portion of said thrust plate and disposed between it and a means adapted to be in contact with the shaft.
Claim 6
Dependent Claim
59 words
A device as set forth in claim 4 wherein the axial bearing includes the radial flange portion of said thrust plate, a washer, a counterplate, an elastomeric cushion, and rolling elements positioned between said radial flange portion of said thrust plate and said counterplate, said axial bearing being disposed against the washer to which said elastomeric cushion is attached.
Claim 7
Dependent Claim
33 words
A device as set forth in claim 5, including an axail skirt, wherein the radial flange portion of said thrust plate, said couterplate and said washer are retained together by said axial skirt.
Claim 8
Dependent Claim
37 words
A device as set forth in claim 1, wherein at least a portion of said bearing ring overlies and is adapted to axially guide at least a portion of the axially extending portion of said thrust plate.
Claim 9
Dependent Claim
87 words
A device as set forth in claim 5, wherein said device includes a hollow vehicular suspension arm, a hollow shaft mounted inside said suspension arm by said bearing device, said hollow vehicular suspension arm having a radial shoulder therein and said radial bearing ring is fitted inside said arm with said thrust plate against said radial shoulder, said second mentioned rolling elements bearing against the outer surface of said hollow shaft and said elastomeric cushion acting against the washer disposed on one end of said hollow shaft.
Claim 10
Dependent Claim
79 words
A combined bearing device having rolling elements comprising: a radial bearing ring and a thrust plate,, said radial bearing ring having an outward facing "U" shaped circumferential groove formed in its outermost surface in one terminal portion thereof, a portion of said thrust plate positioned within said groove and slidably engaged and axially movable between the sidewalls of said groove, said sidewalls being adapted to act as stops to limit axial movement of said thrust plate in two directions.
Claim 11
Dependent Claim
79 words
A combined bearing device having rolling elements comprising: a radial bearing ring and a thrust plate,, said radial bearing ring having an outward facing "U" shaped circumferential groove formed in its outermost surface in one terminal portion thereof, a portion of said thrust plate positioned within said groove and slidably engaged and axially movable between the sidewalls of said groove, said sidewalls being adapted to act as stops to limit axial movement of said thrust plate in two directions.
