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 (12) having a radially outwardly directed flange (16) at one axial end for mounting the wheel of a vehicle, an outer ring (26) having axially spaced raceways (22, 24) and a plurality of rolling elements arranged in two rows (Ri, Ro) in the annular space between the outer ring (26) and the hub (12), the diameter (Do) of the pitch circle of the outboard row (Ro) of rolling elements adjacent said flange (16) being greater than the diameter (Di) of the pitch circle of the rolling elements in the inboard row (Ri) wherein the contact angles of the inner and outer rows of rolling elements intersect the rotational axis (A-A) of the hub (12) at pressure centers (Pi, Po) to define a pressure base between the pressure centers (Pi, Po) and wherein the diameter (Do) of the pitch circle of said outer row (Ro) is at least five mm greater than the diameter (Di) of the pitch circle of the inboard row (Ri) of rolling elements providing higher moment stiffness, better distribution of the load on the bearings and reducing the moment acting on the flange (16).
