Abstract
Abstract A bearing assembly for securing a wheel to a vehicle includes a spindle having a shaft portion defining a longitudinal bore. A flange, adapted for connection to the wheel, projects radially outward from the shaft portion. A threaded region is positioned at one end of the shaft, and a radial shoulder is positioned between the threaded region and the flange. The bearing assembly also includes a driven axle fixedly mounted within the longitudinal bore of the spindle, and a carrier mounted over the shaft portion of the spindle between the threaded region and the radial shoulder. The carrier is adapted for connection to the vehicle. The bearing assembly further includes a pair of tapered bearings mounted between the shaft portion of the spindle and the carrier, and a compression member threaded on the threaded region of the shaft portion for pre-loading the tapered bearings. The bearings are pre-loaded by threading the compression member on the threaded region such that the tapered bearings are axially compressed between the radial shoulder of the spindle and the compression member.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
198 words
A bearing assembly for securing a wheel to a vehicle, the bearing assembly comprising: a spindle including a shaft portion defining a longitudinal bore, the spindle including a flange that projects radially outward from the shaft portion adjacent a first end of the shaft portion, the flange being adapted for connection to the wheel, the spindle also including a threaded region positioned at a second end of the shaft, and a radial shoulder positioned between the threaded region and the flange; a driven axle fixedly mounted within the longitudinal bore of the spindle; a carrier mounted over the shaft portion of the spindle between the threaded region and the radial shoulder, the carrier being adapted for connection to the vehicle; a pair of tapered bearings mounted between the shaft portion of the spindle and the carrier for allowing the spindle to be rotated relative to the carrier; and a compression member threaded on the threaded region of the shaft portion for pre-loading the tapered bearings, wherein the bearings are pre-loaded by threading the compression nut on the threaded region such that the tapered bearings are axially compressed between the radial shoulder of the spindle and the compression member.
Claim 2
Dependent Claim
198 words
A bearing assembly for securing a wheel to a vehicle, the bearing assembly comprising: a spindle including a shaft portion defining a longitudinal bore, the spindle including a flange that projects radially outward from the shaft portion adjacent a first end of the shaft portion, the flange being adapted for connection to the wheel, the spindle also including a threaded region positioned at a second end of the shaft, and a radial shoulder positioned between the threaded region and the flange; a driven axle fixedly mounted within the longitudinal bore of the spindle; a carrier mounted over the shaft portion of the spindle between the threaded region and the radial shoulder, the carrier being adapted for connection to the vehicle; a pair of tapered bearings mounted between the shaft portion of the spindle and the carrier for allowing the spindle to be rotated relative to the carrier; and a compression member threaded on the threaded region of the shaft portion for pre-loading the tapered bearings, wherein the bearings are pre-loaded by threading the compression nut on the threaded region such that the tapered bearings are axially compressed between the radial shoulder of the spindle and the compression member.
Claim 3
Dependent Claim
40 words
The bearing assembly of claim 1, further comprising a radial seal extending radially between the carrier and the compression member for retaining grease within the carrier, wherein the driven axle extends through a central opening defined by the radial seal.
Claim 4
Dependent Claim
30 words
The bearing assembly of claim 2, wherein the compression member has a smooth cylindrical outer surface that maintains a sliding engagement with the radial seal when the spindle is rotated.
Claim 5
Dependent Claim
19 words
The bearing assembly of claim 1, further comprising means for allowing torque to be applied to the compression member.
Claim 6
Dependent Claim
30 words
The bearing assembly of claim 4, wherein the means for allowing torque to be applied comprises a plurality of notches circumferentially spaced about an axial face of the compression member.
Claim 7
Dependent Claim
22 words
The bearing apparatus of claim 5, wherein each notch has a depth less than 1/4 a total thickness of the compression member.
