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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
176 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 same to wheel and brake disc, third connecting means on the flange of said one member circumferentially spaced from said first connecting means, the pitch diameter of the pitch circle of said rolling elements being at least twice the overall axial width of said annular members, at least two of said connecting means being spaced closely to the pitch circle of the rolling elements 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
176 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 same to wheel and brake disc, third connecting means on the flange of said one member circumferentially spaced from said first connecting means, the pitch diameter of the pitch circle of said rolling elements being at least twice the overall axial width of said annular members, at least two of said connecting means being spaced closely to the pitch circle of the rolling elements 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
22 words
A preassembled support as claimed in claim 1 wherein said third connecting means is connected to the calliper housing of the brake.
Claim 4
Dependent Claim
36 words
A preassembled support as claimed in claim 1 wherein all of said connecting means are closely spaced to the pitch circle of the rolling elements and at substantially the same radial distance from the central axis.
