Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
119 words
A hub bearing assembly for the wheel of a motor vehicle comprising a wheel flange having means for mounting the wheel of the vehicle thereto and a drive joint including a sleeve member, a rolling bearing assembly mounted on the outer periphery of the sleeve member, said wheel flange and sleeve member having confronting interengaging means, said wheel flange having a threaded central bore of a pitch differing from the pitch of a threaded bore of said sleeve member and a threaded bolt with differential thread portions engageable in the aligned threaded bores of said wheel flange and sleeve member to permit axial adjustment of said wheel flange and sleeve member and engagement or disengagement of said interengaging means.
Claim 2
Dependent Claim
119 words
A hub bearing assembly for the wheel of a motor vehicle comprising a wheel flange having means for mounting the wheel of the vehicle thereto and a drive joint including a sleeve member, a rolling bearing assembly mounted on the outer periphery of the sleeve member, said wheel flange and sleeve member having confronting interengaging means, said wheel flange having a threaded central bore of a pitch differing from the pitch of a threaded bore of said sleeve member and a threaded bolt with differential thread portions engageable in the aligned threaded bores of said wheel flange and sleeve member to permit axial adjustment of said wheel flange and sleeve member and engagement or disengagement of said interengaging means.
Claim 3
Dependent Claim
34 words
A hub bearing assembly as claimed in claim 1 wherein said threaded bolt includes a radially outwardly projecting circumferentially extending flange defining a centering surface for a wheel and/or a brake disc mounted thereon.
Claim 4
Dependent Claim
57 words
A hub bearing assembly as claimed in claim 1 wherein the threaded bolt has a central bore and a multi-faceted planar surface formed therein for engagement by a fastening key of complementary configuration which when inserted therein affects rotation of the threaded bolt to secure the wheel disc for rotation with the sleeve member of the joint.
Claim 5
Dependent Claim
34 words
A hub bearing assembly as claimed in claim 1 wherein said interengaging means comprises gear teeth at one end of said wheel flange adapted to mesh with gear teeth formed on the sleeve member.
Claim 6
Dependent Claim
91 words
A hub bearing assembly as claimed in claim 1 wherein said bearing assembly includes a pair of side-by-side inner rings and wherein said wheel flange has an abutment shoulder confronting the axial end face of one of said inner rings and said sleeve member is formed with a shoulder confronting an axial end face of the other inner ring whereby upon axial movement of said sleeve member and wheel flange toward one another, the rings of said bearing assembly are pressed together and thus the rolling bearing is adjusted or preloaded.
Claim 7
Dependent Claim
36 words
A hub bearing assembly as claimed in claim 1 wherein the pitch of the threads of the threaded bore of said sleeve member is greater than the pitch of the threaded bore of said wheel flange.
