Abstract
Abstract Wheel bearing pulser combinations of the type where an annular pulser is force fitted onto the outer surface of a wheel bearing are disclosed in which the pulser is constructed to accommodate resiliently resisted radial expansion of its central opening as required by the force fitting of the pulser onto the bearing to permit increased dimensional tolerances of the bearing while avoiding an undue radial compression of the outer race of the bearing from the force fit.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
113 words
In a wheel bearing pulser combination wherein said bearing includes an outer race formed with a generally cylindrical pulser seating external surface and wherein an annular pulser is formed with a central opening therethrough dimensioned to receive said seating surface in a force fitted relationship to mount said pulser on said bearing; the improvement wherein said pulser comprises a one piece annular member including an axially extending annular radially inner web defining said central opening, an annular axially extending radially outer web, and web means integrally coupling said inner and outer webs for resiliently resisted radial movement relative to each other, wherein said pulser accommodates resiliently resisted radial expansion of the central opening.
Claim 2
Dependent Claim
113 words
In a wheel bearing pulser combination wherein said bearing includes an outer race formed with a generally cylindrical pulser seating external surface and wherein an annular pulser is formed with a central opening therethrough dimensioned to receive said seating surface in a force fitted relationship to mount said pulser on said bearing; the improvement wherein said pulser comprises a one piece annular member including an axially extending annular radially inner web defining said central opening, an annular axially extending radially outer web, and web means integrally coupling said inner and outer webs for resiliently resisted radial movement relative to each other, wherein said pulser accommodates resiliently resisted radial expansion of the central opening.
Claim 3
Dependent Claim
17 words
The invention defined in claim 1 wherein said pulser further comprises means defining an axially extending slit.
Claim 4
Dependent Claim
22 words
The invention defined in claim 2 wherein said annular member comprises a generally axially extending annular web of relatively thin resilient metal.
Claim 5
Dependent Claim
18 words
The invention defined in claim 3 wherein said annular web is of an arcuately curved axial cross-sectional configuration.
