  • Publication number: 20180326782
    Abstract: The invention relates to a wheel bearing unit including a wheel hub. The wheel hub has an integrally formed wheel flange at one end and an inner ring which can be rotated together with the wheel hub. The inner ring is secured on the wheel hub by a rolling rivet connection in order to pretension a row of rolling elements relative to an outer ring. The wheel bearing unit also has an encoder, which is provided on the inner ring and extends radially in the direction of the outer ring, and a protective cover which is secured to the outer ring in order to close and seal annular openings that are formed between the outer ring and the wheel hub. A cylindrical mounting section of the protective cover is pressed into a cylindrical press-in portion of the outer ring, and a shielding section extends from the cylindrical assembly portion inwards in a radial direction (R1).

  • Patent number: 9689431
    Abstract: A seal arrangement (1) of an anti-friction bearing, which seal arrangement (1) is inserted between a first bearing part (2) and a second bearing part (4). The seal arrangement includes a seal (6) which is positioned on the rotationally fixed first bearing part by a support element (15) which is enclosed at least on one side by an elastic seal material (16), and which seal (6) includes at least one sealing lip (25, 26). A thrower ring (7), forming a collection chamber (13), of the seal arrangement is assigned to the second rotatable bearing part. To this end, a cylindrical portion (9) of the thrower ring is snapped in an end-side circumferential groove (11) by a flange (5) of the second rotatable bearing part. A radial leg (12) of the thrower ring extends such that it maintains a sealing gap (14) to the seat. Moreover, the seal of the seal arrangement includes elastic sealing lips which are supported on the second bearing part such that they are offset with respect to the thrower ring.

  • Patent number: 9545822
    Abstract: In summary, provided is a wheel bearing unit having a cover element which can be used as a pre-seal to a main seal and encloses the fastening elements of the wheel flange. The outstanding sealing effect has been favored in the past, however a disadvantage in terms of assembly and dismantling is produced which the invention seeks to eliminate. Therefore one or more openings are provided which are formed in the cover. The opening or openings enable the simple dismantling or assembly of the fastening elements on the wheel flange and can advantageously also be closed, such that both the sealing effect and an easy dismantling or assembly are possible.
