Abstract
Abstract A preassembled wheel support unit having inner and outer annular members with confronting raceways for relative rotation and means for connecting one annular member to the vehicle and the other annular member to the wheel and brake disk. The pitch diameter of the raceways is at least twice the overall axial width of the annular members whereby forces resulting from functioning of the brake are acting at substantially the same diameter and close to forces from the wheel and reaction forces from the vehicle. A drive coupling member is connected to the inner annular member.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
163 words
A preassembled support for a disc-braked wheel of an engine propelled road vehicle comprising inner and outer annular members relatively rotatable about a central axis, said annular member having confronting raceways, a plurality of rolling elements in the annular space between said raceways, each of said members having a radially directed flange, first connecting means on the flange of one of said members for detachably connecting the same to the vehicle, second connecting means on the flange of said other member for connecting the wheel and brake disc, and a coupling member connected to said other annular member, the pitch diameter of the pitch circle of said rolling elements being at least twice the overall axial width of said annular members, said connecting means being spaced closely to the pitch circle of the rolling element whereby forces resulting from functioning of the brake are acting at substantially the same diameter and close to forces from the wheel and reaction forces from the vehicle.
Claim 2
Dependent Claim
163 words
A preassembled support for a disc-braked wheel of an engine propelled road vehicle comprising inner and outer annular members relatively rotatable about a central axis, said annular member having confronting raceways, a plurality of rolling elements in the annular space between said raceways, each of said members having a radially directed flange, first connecting means on the flange of one of said members for detachably connecting the same to the vehicle, second connecting means on the flange of said other member for connecting the wheel and brake disc, and a coupling member connected to said other annular member, the pitch diameter of the pitch circle of said rolling elements being at least twice the overall axial width of said annular members, said connecting means being spaced closely to the pitch circle of the rolling element whereby forces resulting from functioning of the brake are acting at substantially the same diameter and close to forces from the wheel and reaction forces from the vehicle.
Claim 3
Dependent Claim
18 words
A preassembled support as claimed in claim 1 for a driven wheel of an engine propelled road vehicle.
Claim 4
Dependent Claim
20 words
A preassembled support as claimed in claim 1 wherein said coupling member is formed integrally with said other annular member.
Claim 5
Dependent Claim
17 words
A preassembled support as claimed in claim 3 wherein said other annular member is the inner member.
Claim 6
Dependent Claim
54 words
A preassembled support as claimed in claim 1 wherein said annular members are of L-shaped cross section and the connecting means comprises a plurality of openings in the flanges located at approximately the same diameter, one of said annular members being stationary and having additional openings for the attachment of a stationary brake part.
Claim 7
Dependent Claim
93 words
A wheel bearing unit for use in a vehicle according to claim 1, characterized in that the flanges of both structural members extend parallel radially outwardly, the flange of the inner member having a number of holes for the connection to the wheel and the flange of the outer member having holes for the connection to the vehicle at the same diameter and mutual spacing as the holes in the flange of the inner member as well as holes for the attachment of the stationary brake part, which holes have a different spacing.
