Definitions
- the invention relates to a cartridge seal, in particular for a wheel bearing assembly of a motor vehicle, comprising a first and a second ring, which have an approximately L-shaped cross-section, wherein the axial portions and the radial portions of the first and second ring are aligned approximately parallel to each other, such that an inner space is formed, in which a, arranged on the first ring sealing arrangement engages in the direction of the second ring and between the radial portion of the first ring and the axial portion of the second ring, a gap is formed, wherein at the Interior side facing away from the axial portion of the second ring an encoder extends and a wheel bearing assembly.
- a known per se cartridge seal 1 as shown in Figure 1, has two, an approximately L-shaped cross-section having rings 3 and 4, wherein the axial portions of the rings 3 and 4 and the radial portions of the rings 3 and 4 approximately are aligned parallel to each other. The rings 3 and 4 thereby form an interior space 6.
- a sealing arrangement 5 is vulcanized onto the first ring 3, the sealing lips 5a, 5b, 5c of which extend in the direction of the second ring 4 in the interior 6.
- a cylindrical encoder 7 is mounted, which comprises the free end of the axial section 8.
- the free end of the radial portion of the first ring 3 forms with, the free end 8 of the
- a cartridge seal 2 is shown, as is also known, wherein the encoder 7 at the end of the axial portion of the second ring 4, a so-called twin-axis design with two, in the direction of the radial portion of the first ring 4 facing lips 7a, 7b having.
- this embodiment makes it possible to reclaim ingress of dirty water by the rotation of the encoder 7, but requires an enlarged radial installation space.
- the invention is therefore an object of the invention to provide a cassette seal, which allows an unchanged sealing space with unchanged space of the wheel bearing.
- the object is achieved in that the encoder expands in the direction of the radial portion of the first ring over the axial portion of the second ring and in this area has a sloping in the direction of the second ring bevel, wherein the bevel with the radial portion of first ring forms the gap. Due to this optimized entrance gap geometry a recirculation effect of the dirty water while maintaining the dimension of the wheel bearing is possible. The formation of an accumulation of water can be avoided by taking advantage of the centrifugal forces occurring during the rotational movement of the wheel bearing, since the fluid accumulation is given by the bevel the possibility for flow. Penetration of dirt into the cassette sealing system is thus reduced.
- the encoder is formed ring-like, wherein the encoder is wider than the axial portion of the second ring.
- the bevel can thus be realized in a simple manner on one side of the encoder ring.
- the bevel of the encoder protrudes into the interior. Due to the fact that the chamfer protrudes into the inner space between the first and the second ring via the axial section, the gap geometry is optimized without requiring more space for the cartridge seal and thus for the wheel bearing arrangement.
- the bevel of the encoder terminates with the side of the axial section of the second ring facing away from the interior, the bevel near the axial section of the second ring having an annular recess. This depression forms a gutter for the contaminants, which can run on the outward chamfer on the circulation of the cassette ring.
- the encoder has a twin in the region that extends beyond the axial portion of the second ring.
- a further development of the invention relates to a cartridge seal, in particular for a wheel bearing assembly of a motor vehicle, comprising a first and a second ring, which have an approximately L-shaped cross section, wherein the axial portions and the radial portions of the first and second ring approximately are aligned parallel to each other, so that an inner space is formed, in which a, arranged on the first ring sealing arrangement engages in the direction of the second ring and between the radial portion of the first ring and the axial portion of the second ring, a gap is formed on the, remote from the interior side of the axial portion of the second ring a fixed arranged additional element extends and the additional element rises in the direction of the radial portion of the first ring over the axial portion of the second ring with a projection.
- the projection of the additional element projecting beyond the axial section of the second ring has a bevel sloping in the direction of the second ring, the bevel coinciding with the radial section of the first Ringes forms the gap and the supernatant is preferably lipless.
- the formation of an accumulation of water can be avoided by taking advantage of the centrifugal forces occurring during the rotational movement of the wheel bearing, since the fluid accumulation is given by the chamfer the possibility for flow. Penetration of dirt in the cassette end density system is thus reduced.
- the projection of the additional element comprises one end of the axial portion of the second ring, wherein the chamfer protrudes into the interior.
- the gap geometry is optimized without more space for the cartridge seal and thus for the wheel bearing assembly is needed.
- the bevel of the supernatant of the additional element is stepped. By such a stepped formation of the chamfer, a labyrinth-like portion is formed. Through this labyrinth arrangement, the input region of the gap opens into a radially outwardly leading annular space, which realizes the function of collecting and returning back soiling. The return of the contaminants is caused by the centrifugal forces occurring during the rotational movement of the wheel bearing.
- the bevel of the supernatant of the additional element terminates with the, the interior side facing away from the axial portion of the second ring, wherein the bevel close to the axial portion of the second ring has an annular recess.
- This depression forms a gutter for the dirt and can run on the outward bevel on the circulation of the cassette ring. Penetration of the contamination in the interior of the cassette seal is thus reliably prevented.
- the radial section of the first ring has an axial extension above the projection of the additional element, which preferably extends in approximately one plane with the axial section of the second ring. Through this axial extension of the gap is opened to the outside, so that a return of the waste water located in the gap is facilitated by the resulting funnel-shaped opening.
- the additional element is designed as a seal.
- This seal and the sealing arrangement, which is arranged on the first ring, can be made of the same material and can thus be produced very inexpensively.
- the additional element is designed as an encoder.
- This encoder cooperates with a speed sensor, by means of which, due to the arrangement of the wheel bearing, the speed of the wheel can be determined.
- the arrangement of the encoder on the cartridge seal makes optimum use of the installation space of the wheel bearing. An increase in the space for the wheel bearing to the arrangement of the encoder can thus be omitted.
- the encoder consists of a, ferromagnetic materials containing sealant.
- a low cost vulcanized to the second ring of the cassette seal must be provided only with appropriate ferromagnetic materials, making the encoder is easy to manufacture.
- the wheel bearing arrangement according to the invention in particular for a motor vehicle, comprises a cassette seal according to at least one of the features described in this patent application.
- FIG. 3 shows a basic illustration of a rolling bearing for a wheel bearing arrangement with a first embodiment of a cartridge seal according to the invention

- the rolling bearing 10 is equipped with a sealing device in the form of a cassette seal 15, which prevents the penetration of water and dirt into the rolling bearing 10.
- Figures 4a to 4e Various embodiments of the cartridge seal are shown in Figures 4a to 4e.
- the cassette seal 15 shown in FIG. 4a corresponds to the cassette seal, as shown in FIG.
- the cassette seal 15 of Figure 4a consists of two, an L-shaped cross-section rings 3 and 4, wherein each of the axial portion 3a of the first ring 3 is aligned parallel to the axial portion 4b of the second ring 4.
- These sealing lips 5a, 5b and 5c extend in the direction of the second ring 4 and are aligned both radially and axially.
- an encoder 7, which is supported by the second ring 4, is arranged on the side facing away from the interior 6 in its longitudinal extent.
- the encoder 7 cooperates with a sensor arrangement, not shown, in order to be able to electronically measure the rotational speed of a component mounted by the roller bearing 10.
- the wheel speed is thus determined, for example. This wheel speed is in ABS, ASR and / or
- ABS Anti-lock Braking System
- ASR Anti-Slip Regulation
- ESP Electronic Stabilization Program Control
- the encoder 7 consists of a sealing material from which the seal assembly 5 may be made, with the difference that the sealing material of the encoder 7 ferromagnetic materials are added, so the encoder 7 serves as a signal generator for the speed sensor.
- the encoder 7 extends beyond the axial section 4b of the second ring 4 beyond the latter and has a lip-free projection 16, which has a bevel 17 sloping in the direction of the interior 6 of the cassette seal 15.
- the projection 16 comprises the axial portion 4b of the second ring 4.
- the first ring 3 has an axial extent 3c which extends from the axial portion 4b of the second Ring 4 away pointing at right angles to the radial portion 3b of the first ring 3 connects.
- the extension 3c may preferably be formed as a flared edge of the first ring 3 consisting of a sheet metal.
- the bevel 17 of the encoder 7 is approximately a bend 3d between the radial portion 3b and the axial extent 3c of the ring 3 opposite and forms together with the first ring 3, the gap 9.
- This gap 9 which acts like a throttle prevented the direct ingress of dirt by deflecting the inlet beam on the bevel 17 under the dynamic conditions of the wheel bearing.
- This gap 9 which acts like a throttle prevented the direct ingress of dirt by deflecting the inlet beam on the bevel 17 under the dynamic conditions of the wheel bearing.
- This geometry of the gap 9 is particularly suitable for use in the field of confined space conditions of a wheel bearing with simultaneous arrangement of speed sensors, without additional space for the design of a gap 9 is required, which reliably the return effect of dirty water during rotation of the encoder. 7 causes.
- the cartridge seal 19 in FIG. 4 b differs from FIG. 4 a in that the projection 16 of the encoder 7 has a step 18.
- Gap 9 formed in the form of a labyrinth, which is an intrusion of

- a seal 22 is vulcanized, which consists of a material that corresponds to the material of the seal assembly 5.
- the seal 22 has a projection 16 whose bevel 17 terminates in front of the end 8 of the axial section 4b of the second ring 4 and has an annular groove 21 near this end 8.
- This annular groove 21 is disposed approximately directly opposite the bend 3d between the radial portion 3b and the axial extent 3c of the first ring 3.
- the annular groove 21 catches the dirty water and prevents it from entering the interior 6 of the cassette seal 20.
- an encoder 7 is again vulcanised onto the axial section 4b of the second ring 4, which likewise has an annular groove 21 for collecting the dirty water.
