Wheel bearing unit with a wheel hub, wherein the wheel hub has an integrally formed wheel flange on one end thereof and an inner ring that is rotatable together with the wheel hub, wherein the inner ring is fastened on the wheel hub through the use of a rolling rivet connection in order to pre-tension a row of rolling elements in relation to an outer ring, and with an encoder provided on the inner ring and extending radially towards the outer ring, and with a protective cover fixed on the outer ring in order to close and seal annular openings formed between the outer ring and the wheel hub, and wherein a cylindrical section of the protective cover is pressed in and wherein a bottom section extends inwardly from the cylindrical section in a radial direction in order to cover an inner-side end of the wheel hub, wherein the cylindrical section is joined with a substance bond to the outer ring and wherein the substance-bond connection is produced through the use of a hardening fluid and wherein the fluid is held in a filling reservoir provided between the cylindrical section and the outer ring.
A wheel bearing unit comprising a wheel hub having on one end an integrally formed wheel flange, an inner ring that rotates together with the wheel hub, the inner ring is fastened on the wheel hub with a rolling rivet connection in order to pre-tension a row of roller elements relative to an outer ring, an encoder on the inner ring that extends radially in a direction of the outer ring, a protective cover is fixed on the outer ring in order to close and seal ring-shaped openings that are formed between the outer ring and the wheel hub, the protective cover is pressed in with a cylindrical section and has a bottom section that extends inward from the cylindrical section in a radial direction in order to cover an inner end of the wheel hub, the cylindrical section is connected to the outer ring with a substance bond connection by injection of a hardening fluid in a reservoir that is provided between the cylindrical section and the outer ring, the reservoir is axially spaced away from both axial ends of the cylindrical section, and the hardening fluid hardens to form a fixed connection between the outer ring and the cylindrical section.
