Abstract
The invention relates to a wheel bearing arrangement which enables a hub to be mounted in at least one non-rotating external ring such that it can rotate about the rotational axis of the hub. The wheel bearing arrangement comprises at least one sealing arrangement and one encoder and the sealing arrangement is secured to the hub side on the side of the wheel bearing arrangement whereon a radial flange extends in a radial manner from the hub. The encoder is actively connected to the sealing arrangement.
Claims22
A wheel bearing arrangement, comprising:
- a hub having a rotational axis and a radial flange mounted about the rotational axis;
- at least one non-rotating outer ring;
- and
- at least one encoder being fixed on the hub where the radial flange leads radially away from the hub,
- wherein the encoder surrounds an annular section of the outer ring in a circumferential manner radially on an outside face of the outer ring without contact, and
- wherein the encoder is surrounded radially, without contact, by a protective sleeve, the protective sleeve having a first hollow-cylindrical section and a second hollow-cylindrical section, the first hollow-cylindrical section being connected integrally to the second hollow-cylindrical section by an additional section providing a space between the first hollow-cylindrical section and the second hollow-cylindrical section with the encoder being positioned in the space between the first hollow-cylindrical section and the second hollow-cylindrical section, the first hollow-cylindrical section being a radially outer most member and the second hollow-cylindrical section being radially inward relative to the first hollow-cylindrical section, and the second hollow-cylindrical section being fixed axially on the outside face of the outer ring.

A wheel bearing arrangement, comprising:
- a hub having a rotational axis and a radial flange;
- at least one non-rotating outer ring having an annular section;
- at least one sealing element;
- and
- one encoder, the encoder being fixed on the hub where the radial flange radially leads away from the hub,
- wherein the encoder surrounds the annular section of the outer ring in a circumferential manner radially on an outside face of the outer ring without contact,
- the encoder and the sealing element form a sealing operative connection,
- wherein the sealing operative connection is at least one gap seal between the encoder and the sealing element, the gap seal having at least one first sealing gap which extends around the rotational axis, and
- wherein the sealing element is a protective sleeve radially surrounding the encoder without contact, the protective sleeve having a first hollow-cylindrical section and a second hollow-cylindrical section, the first hollow-cylindrical section being connected integrally to the second hollow-cylindrical section by an additional section providing a space between the first hollow-cylindrical section and the second hollow-cylindrical section with the encoder being positioned in the space between the first hollow-cylindrical section and the second hollow-cylindrical section and the encoder extending axially along an entire length of the second hollow-cylindrical section, the first hollow-cylindrical section being a radially outer most member and the second hollow-cylindrical section being radially inward relative to the first hollow-cylindrical section, and the second hollow-cylindrical section being seated fixedly in an axial direction on the outside face of the annular section of the outer ring.
