Definitions
- the invention relates to a release bearing assembly for a clutch comprising a
- the release bearing assembly comprises a release bearing, usually a roller bearing, with an outer ring and an inner ring. Between the rings run in a cage guided rolling elements.
- release bearings are used to compensate for a production-related axial impact of the clutch or its disc springs. This measure reduces wear and at the same time improves the service life of the release bearing.
- the release bearing is as stated part of a release bearing assembly and arranged axially displaceable together with a housing on a guide sleeve. The axial displacement takes place via a release lever or a Gottausschreiber, wherein the disengagement can be initiated by means of a clutch pedal or automatically by a clutch actuator.
- the structure of a release bearing usually provides that both the circumferential bearing ring and the torsionally rigid bearing ring is supported via a collar on a plate spring or indirectly or directly on the housing.
- the self-aligning or self-adjusting release bearing compensates for the axis-parallel offset, avoids a clutch picking or adverse vibrations and improves overall comfort.
- Such a self-adjusting or self-aligning release bearing is known for example from DE 101 24 663 A1.
- a bearing ring is provided with a designed as Kugelkalottensegment contact zone, the a complementarily shaped Kugelkalottensegment an adjusting ring is supported, whereby a pivotable arrangement of the release bearing is ensured with respect to the adjusting ring.
- the adjusting ring can be assigned to both the rotating bearing ring and the rotationally fixed bearing ring.
- a sliding element is fixed, for example by a force-locking adhesive. This slider is positioned in the contact zone.
- the invention is therefore based on the problem of specifying a release bearing assembly that is kept simple in construction, but allows compensation of the Kupplungsaxialtschs.
- the bearing ring is associated with a spring-mounted attachment disk, which rests on the coupling side.
- This attachment disc is axially spring-loaded against the bearing ring, so it is axially movable relative to it, as may possibly be implemented a certain Verkipples on the springing.
- the structure of the release bearing assembly according to the invention is very simple, since only an axial attachment disc with integrated or associated spring means is needed.
- the design of special contact surfaces, usually elaborate form and are to be treated in particular surface technology, is advantageously not required in the release bearing assembly according to the invention.
- the attachment disc has an axial collar, with which it radially overlaps the bearing ring. This Axialbund serves the axial guidance of the attachment disc.
- a plurality of spring tongues can be bent out of the attachment disk, by means of which it is spring-loaded on the bearing ring.
- the springiness or springing is thus disc inherent, after the spring tongues are integrally provided on the attachment disc.
- a separate spring means is therefore not provided.
- the bent-out spring tongues are preferably arranged distributed equidistant around the circumference of the bearing disk.
- a spring ring in the form of a wave spring ring, ie a metal ring which has a pronounced wave profile.
- a metal ring which has a pronounced wave profile.
- an elastomer ring it is also conceivable to use an elastomer ring.
- any plastic material is suitable, which offers sufficient spring properties.
- elastomeric ring If such an elastomeric ring is used, then it can be made planar on both sides, d. that is, the spring property is provided solely by the volume of the elastomeric ring. It is also conceivable, however, to use an elastomer ring which has at least one preferably wavy profiled axial annular surface. The spring characteristic is thus additionally provided by the profiling. Of course, it is also possible in this context to profile both sides, for example against the same.

- Release bearing assembly 1 which is shown in Figures 2 and 3 are each partially in section.
- the release bearing assembly 1 comprises a release bearing 2 comprising an inner ring 3 and an outer ring 4, wherein between the two rings in a cage 5 guided rolling elements 6, here balls, run. It is in the illustrated embodiment is an angular contact ball bearings.
- the inner ring 3 is arranged on an inner sleeve 7, it engages with its radial annular collar 8 in a corresponding sleeve recess 9 and is secured there by a spring ring 10.
- the release bearing assembly 1 further comprises an attachment plate 1 1, preferably a metal disc, for example, deep-drawn. It has a radial disk body 12, from which an axial collar 13 protrudes.
- a plurality of spring tongues 14 are punched in the example shown and bent in the direction of Axialbunds 13. So they point to the outer ring 4 of the release bearing 2.
- the Axialbund 13 engages over the outer ring 4.
- the spring tongues 14 are applied to the radial collar 15 of the outer ring 4, so consequently the attachment disc 1 1 over this relative to the release bearing 2 and the outer ring 4 is spring-loaded.
- Under load it is, see Figure 3, axially movable in the direction of the outer ring 4, they can create a maximum area of the radial collar 15 of the outer ring 4, as shown in Figure 2.
- the spring tongues spring.
- This spring bearing respectively this Einfeder einberg is made it possible to catch any of the coupling side, on which the attachment plate 1 1 is applied, recorded vibrations respectively to compensate and not pass on the Aus Weglageran extract or if at all only in a muffled manner.
- this attachment disc also offers the opportunity for self-adjustment due to the spring bearing to compensate for any misalignment or tolerances after being, as stated, spring-loaded relative to the release bearing 2 and movable.
- Figures 4 and 5 show another example of a release bearing assembly 1, wherein the same reference numerals are used for the same components. Shown in turn is a release bearing 2 comprising an inner ring 3 and an outer ring 4, between which in turn run in a cage 5 rolling elements 6 run.
- the basic structure corresponds to that, as it is known from Figures 1-3.
- an attachment disc 1 1 is provided, comprising a disk body 12 and an axial collar 13, with which the attachment disc 1 1, the outer ring 4 radially overlaps.
- a spring ring 16 in the form of a wave spring ring 17 is set between the disk body 12 and the radial collar 15 of the outer ring 4.
- This wave spring ring 17 abuts both the attachment disc 1 1 and the annular collar 15. Due to its undulating profiling, he spaced both from each other, but is compressed under load of the attachment disc 1 1, so springs, so again an axial movement of the attachment disc 1 1 relative to the release bearing 1 for vibration compensation respectively for self-adjustment is possible.
- Figures 6 and 7 show a third embodiment of an inventive
- self-adjusting release bearing assembly in turn comprising a release bearing 2 with an inner ring 3 and an outer ring 4 with running therebetween, guided in a cage 5 rolling elements 6. It is again provided an attachment disc 1 1 with a disk body 12 and an axial collar 13, in accordance with the mounting position Figure 7 radially overlaps the outer ring.
- a spring ring 16 is set between the disk body 12 and the radial collar 15 of the outer ring 4, both spaced from each other.
- the spring ring 16 is here, however, designed as an elastomeric ring 18, so it is made of a sufficiently soft material over which the attachment disc 1 1 is thus sprung relative to the outer ring 4. If here again the attachment disc 1 1 loaded axially by operating the clutch, so there is a deformation of the elastomeric ring 18 and thus to a relative movement of the attachment disc 1 1 to the release bearing 2, resulting on the one hand compensation for any vibrations respectively the clutch beat, on the other hand a certain self-adjustment is possible.
- FIGS. 6 and 7 show an elastomer ring 18 with two planar axial end faces, it is, of course, possible to profile one or both end faces, for example via (in each case) a wave profile.
- FIG. 8 shows a self-aligning release bearing arrangement 1 according to the invention with a release bearing 2 with inner ring 3, outer ring 4 and rolling elements 6 guided in a cage 5.
- a radial flange 19 is formed here on the inner ring 3.
- the attachment disc 1 1 which in turn is, for example, an attachment disc 1 1 with corresponding spring tongues 14 which are bent out of the disk body 12. With an axial collar 13 here, too, the attachment disc 1 1 engages over the radial flange of the inner ring 3.
