Wheel bearing arrangement for motor vehicles

Abstract

A wheel mounting for automotive vehicles substantially comprising a multi-row angular contact rolling bearing comprising an inner bearing ring arranged on or at least partially integrated in a hub of a wheel side-fixing flange, an outer bearing ring coaxial to the inner bearing ring and arranged in or at least partially integrated in a hub of a vehicle side-fixing flange, and a plurality of rolling elements arranged in a plurality of rows next to one another between the inner and the outer bearing rings, which rolling elements roll on defined, inclined pressure angle axes in groove-shaped raceways of the inner and the outer bearing rings and are retained uniformly spaced from one another in peripheral direction in a plurality of bearing cages wherein all the rolling elements of the angular contact rolling bearing are configured in form of ball-rollers comprising two parallel side surfaces obtained by symmetric flattening of a basic ball shape such that a width of the ball-rollers between these side surfaces is 20% to 30% smaller than a diameter of the basic ball shape.
