Abstract

A hub bearing assembly comprising a hub having a radially outwardly directed flange at one axial end for mounting the wheel of a vehicle, an outer ring having axially spaced raceways and a plurality of rolling elements arranged in two rows in the annular space between the outer ring and the hub, the diameter of the pitch circle of the outboard row of rolling elements adjacent said flange being greater than the diameter of the pitch circle of the rolling elements in the inboard row.

Claims

1. A hub bearing assembly comprising a hub having a radially outwardly directed flange at one axial end for mounting the wheel of a vehicle, an outer ring having axially spaced raceways and a plurality of rolling elements arranged in two rows in the annular space between the outer ring and the hub, the diameter of the pitch circle of the outboard row of rolling elements adjacent said flange being greater than the diameter of the pitch circle of the rolling elements in the inboard row.

2. A hub bearing assembly as claimed in claim 1 wherein the rolling elements of both rows are balls.

3. A hub assembly as claimed in claim 1 wherein the rolling elements of said outboard row are balls and the rolling elements of the other inboard row are tapered rollers.

4. A hub assembly as claimed in claim 1 wherein the diameter of the pitch circle of said outer row is at least five mm greater than the diameter of the pitch circle of the inboard row of rolling elements.
