Definitions
- the present invention relates to a sealing arrangement for sealing a (roller) bearing, the sealing arrangement having a sealing element with at least one sealing lip which rests sealingly on an associated contact surface, as claimed in claim 1, and a wheel bearing as claimed in claim 10.
- Rolling and plain bearings are used to support a rotating component, e.g. a shaft.
- the rolling bodies which are located in such bearings, are susceptible to contamination in the form of foreign particles or liquids.
- the interior of these bearings must therefore be tightly sealed to prevent dirt or liquid from penetrating.
- Such a sealing effect in particular in the case of wheel bearings of a motor vehicle, is usually achieved by contact between a plurality of dynamic sealing lips of a first sealing element and a rotating counter surface.
- sealing arrangements for sealing a roller bearing between a first and a second bearing part are known from JP 2015-152 030 A and KR 10-2013 0 087 875.
- the seal assemblies include a standing seal disk having at least one sealing lip axially sealingly contacting a contact surface of a second rotating seal disk, and a radial gap seal.
- the design of the overlap of the sealing lip or the seal with the rotating contact surface is dependent on the (axial) position of a centrifugal disc, which is subject to tolerances.
- the effect of the axially aligned sealing lip is sensitive to the mutual positioning of the stationary sealing disk and the rotating sealing disk. This means that the position tolerances of the flinger directly affect the overlap of the axial Sealing lips affects.
- a nominal sealing lip overlap / overlap In order to cushion / mitigate the positional tolerances, a nominal sealing lip overlap / overlap must be defined. A minimum overlap between a sealing lip and the contact or counter surface is required to ensure an adequate sealing function, whereas a maximum overlap should not be exceeded in order to keep the friction between the two components as low as possible.
- the object of the present invention is to avoid or at least alleviate the disadvantages of the prior art and in particular to further develop a sealing arrangement for a wheel bearing in which the influence of an (axial) positioning of the centrifugal disc on the resulting overlap between a sealing lip and the opposing contact surface is reduced.
- a sealing arrangement for sealing a bearing with an inner and an outer bearing ring with the features of patent claim 1, namely that a thrust surface / counter surface or contact surface of a rotating carrier element, on which a sealing lip rests sealingly, in a Angle between 0 ° and 90 °, based on a horizontal, is formed in the direction of the outer bearing ring.
- a sealing arrangement can be provided in which a tolerance-dependent positioning of a centrifugal disk has less influence/impact on the sealing lip overlap between a sealing lip and an opposing contact surface, i.e. the theoretical overlap of the sealing lip and the contact surface.
- the invention relates to a sealing arrangement for sealing a bearing, in particular a wheel bearing, with an inner rotatable bearing ring and an outer stationary bearing ring.
- the sealing arrangement has an inner carrier element/sealing disk connected to the inner bearing ring and an outer carrier element/sealing disk connected to the outer bearing ring.
- a first sealing element with at least one sealing lip is formed on the outer carrier element, which abuts/lies sealingly on a contact surface/abutting surface/counter running surface of the inner carrier element.
- the contact surface of the inner support element is formed at an angle of between 0° and 90° with respect to a horizontal in the mounted state of the sealing arrangement in the direction towards the outer bearing ring.
- the sealing arrangement according to the invention has two carrier elements, which are each connected to an inner or outer (relative to the axis of the rotatably mounted component) bearing ring.
- the carrier element arranged on the outer, stationary bearing ring has a sealing element, which in turn has at least one sealing lip that projects/aligns radially or axially.
- the inner carrier element has an inclined contact surface with which the at least one sealing lip can be brought into sealing contact.
- the oblique alignment of the contact surface of the outer carrier element takes place in the direction of the outer bearing ring, specifically at an angle of between 0° and 90° with respect to the horizontal. A theoretical angle of 0° describes an orientation of the contact surface in which the contact surface corresponds to the horizontal. Since the contact surface of the rotating sealing disk is arranged at an angle, the overlapping of the sealing lip is also at an angle or at an angle.
- This oblique arrangement of the contact surface for the sealing lip reduces the influence of the centrifugal disc and thus the rotating carrier element of the sealing arrangement, which is dependent on tolerance or position.
- a (tolerance-related) axial position shift of the centrifugal disc is therefore less Effect on the resulting coverage / overlap between the sealing lip and the associated contact surface of the rotating carrier element.
- This sloping contact surface and the resulting sloping sealing lip overlap can also be used to reduce a nominal sealing lip overlap, with the result that friction losses are kept low, with a correspondingly sufficient sealing effect.
- the sealing lip overlap described above is thus optimized in terms of sealing ability and friction. In particular, this takes place as independently as possible of the tolerances of the centrifugal disc.
- the sealing lip bears against the contact surface of the inner carrier element in the radial direction.
- the sealing lip which can be brought into contact with the oblique/angled contact surface of the inner carrier element, is radial. This means that the sealing lip is slotted in the radial direction.
- a radial design of the sealing lip in combination with the associated, sloping contact surface of the counter-rotating carrier element ensures that no dirty water collects in the area of the sealing lip overlap. Dirty water at the contact point of the sealing lip above the axis of rotation and also below the axis of rotation of the rotating component is able to drain off directly. There is therefore no dirty water reservoir at the sealing contact in comparison to an axial design of the sealing lip.
- the angle between the contact surface of the inner support element and the horizontal is approximately 30°.
- the first sealing element has at least one collecting chamber which is designed and provided to collect dirt and/or liquid.
- the first sealing element forms a notch-shaped trapping chamber which extends along the entire circumference of the sealing element and is intended to trap contaminants. In particular, this prevents splashing water and contamination, such as dust or other foreign particles, from getting into the interior of the bearing. Accordingly, a functional impairment of the bearing is counteracted.
- the two carrier elements of the sealing arrangement are each non-positively connected to their associated two bearing rings.
- the outer carrier element which has the first sealing element, is non-positively connected to the outer bearing of the roller bearing or wheel bearing.
- the internal carrier element is connected to the internal bearing in a non-positive manner.
- Such a non-positive connection is achieved, for example, by means of a press fit. This ensures a secure and relatively strong connection of the components to one another, while keeping manufacturing costs low.
- the inner carrier element of the sealing arrangement has a second sealing element.
- the additional sealing element on the inner carrier element makes it possible to influence the geometry of the sealing space between the two (opposite) carrier elements and additionally protects the inner carrier element from external influences.
- the two carrier elements are arranged axially in such a way that a sealing gap is formed between the first and the second sealing element.
- This sealing gap between the two support elements preferably extends axially for the most part, which increases the axial path for contaminants/dirt particles into the interior of the bearing. Furthermore, this effect can be increased by a stepped profile of the sealing gap in the radial direction.
- At least the second sealing element has at least one trapezoidal sealing projection and at least the first sealing element has at least one trough-shaped depression assigned to it.
- at least one trapezoidal or rectangular sealing projection which is oriented horizontally, is formed in one piece at least on the second sealing element.
- at least the first sealing element has at least one trough-shaped indentation which is formed opposite to the sealing projection of the second sealing element and is assigned to it.
- the trough-like depression encompasses/encloses the associated sealing projection, while maintaining a sufficiently wide sealing gap between the two carrier elements so that an unimpeded rotational movement is ensured.
- the sealing gap is designed in the form of a labyrinth structure made up of a plurality of trapezoidal sealing projections connected in series and the respectively associated trough-shaped depressions.
- a series-connected arrangement of a plurality of sealing projections and the associated depressions in particular in the radial or axial direction, creates a sealing gap between the two carrier elements which has a labyrinth shape/snake shape.
- This series-connected arrangement takes place in the axial or radial direction of the (assembled) sealing arrangement.
- the invention further relates to a wheel bearing for a motor vehicle with the sealing arrangement according to the invention, as claimed in patent claim 10, for example.

- the sealing lip 7 is aligned radially in the direction of the outer bearing ring 3 and is in sealing contact with an obliquely angled contact surface 8 of the inner carrier element 4.
- the contact surface 8 for the sealing lip 7 is at an angle of approximately 30 ° opposite a horizontal, in the direction of the outer bearing ring, formed. Accordingly, the sealing lip 7 bears against this oblique contact surface 8 of the inner carrier element 4 .
- the radial end piece 14 of the first sealing element is formed on the side which faces the inner bearing ring 2 and extends in the axial direction towards the inner carrier element 4, as a result of which an axial gap seal is formed. Furthermore, a second sealing element is formed on the side of the inner carrier element 4 facing away from the sealing space. Both sealing elements 6, 10 are arranged relative to one another in such a way that they form a sealing gap 11 between them, which runs in a stepped manner.
- FIG. 2 shows an isometric cross-sectional view through the transmission side of a wheel bearing with the installed sealing arrangement 1 according to the embodiment shown in FIG.
- the wheel bearing shown consists of the outer bearing ring 3, which in this embodiment is designed as an axle body, and a rotatable inner bearing ring 2, which is connected to a wheel flange 15. Between the inner bearing ring 2 and the outer bearing ring 3, a first and second row of rolling elements 16, 17 are arranged.

- the sloping course of the contact surface 8 of the inner Carrier element 4 with the second sealing element 10 can be seen, on which the sealing lip 7 of the first sealing element 6 rests or rests in a sealing/sealing manner.
- the collecting chamber 9, which is arranged below the sealing lip 7 in this view, is shown for collecting dirt or liquids.
- a plurality of dashed lines are drawn in this representation for illustration purposes.
- the two sloping lines running parallel to one another illustrate a covering/overlapping of the sealing lip 7 and the sloping contact surface 8. Only a theoretical sealing lip covering is shown, which differs from the actual shape of the sealing lip 7 in the assembled state.
- a further horizontal dashed line illustrates the sloping course of the contact surface 8, which runs at an angle a with respect to the horizontal.
- Figures 4 and 5 each show an enlarged (side) cross-sectional view through the sealing contact of the sealing lip 7 of the sealing arrangement 1 according to the first embodiment, with the inner carrier element 4 and the two sealing elements 6, 10.
- the radially aligned sealing lip 7 is in contact with the sloping contact surface 8 of the inner carrier element 4.

- FIG. 6 shows a diagram which shows the dependency between a change in the sealing lip overlap and an angle of the inclined contact surface 8 of the inner carrier element 4 with different axial position changes for the sealing arrangement 1 according to the invention.
- the angle a between 0° and 90° is drawn on the contact surface 8 with respect to a horizontal line on the x-axis of the diagram and each of the seven curves of the set of curves shown indicates an axial change in position of the centrifugal disk or of the inner support element 4 in relation to the outer carrier element 5 of the sealing arrangement 1.
- the individual curves each represent an axial change in position between 0 mm (lowest horizontal curve) and 0.3 mm (top curve).
- a predetermined angle ⁇ for a predetermined change in axial position is associated with a change in the sealing lip overlap (in mm), which is plotted on the y-axis of the diagram.
- an axial change in position of 0.3 mm of the rotating and stationary component to one another leads to a change in the sealing lip overlap of 0.3 mm.
- An axial change in position is thus 100% converted into a change in the overlap of the sealing lip 7 .
- An oblique or angled alignment of the contact surface 8 with respect to a horizontal line leads to a lesser effect of the axial change in position.
- an axial position change of 0.3 mm with a contact surface 8, which is oriented at an angle of 30° to the horizontal only leads to a change in the sealing lip overlap of 0.15 mm. The influence of the axial position change is thus halved compared to the case of the vertical contact surface 8 .
