  • the release bearing assembly comprises a release bearing with an outer ring and an inner ring, between which rolling elements, usually balls, roll.
  • the bearing is designed primarily as a radial tapered bearing.
  • the release bearing is arranged on an inner sleeve, which in turn is suitably coupled to the release element, for example a concentric slave cylinder.
  • the release bearing is clamped via one of its rings with the sleeve via a plate spring, usually this is the inner ring connected via the plate spring with the sleeve, but in principle, the outer ring may be coupled to the sleeve.
  • a labyrinth seal in the area between the rings.
  • this can not be achieved a sufficient seal.
  • it is known to provide a contacting seal, which indeed provides a sufficient seal, however, arise in terms of lubrication in the region of contact of the sealing element on the opposite ring, which perform a relative movement to each other, problems, which often result in excessive stress to excessive wear can.
  • the invention is therefore based on the problem to provide a release bearing assembly, on the one hand a reliable seal, on the other hand offers a sufficient wear resistance respectively lubrication possibility in the sealing element area.
  • a sealing element is arranged a contacting sealing lip and a dust lip on the plate spring, by means of which sealing element the gap is sealed to the other ring.
  • a combination of two lips is used with particular advantage, both of which are arranged on the one hand on the plate spring and fixed on this, and the two to the other ring, against which the plate spring is not braced seal. If the plate spring is clamped, for example, against the inner ring, then the sealing lip is touching the outer ring, its associated dust lip is also adjacent to the outer ring with a minimal gap.
  • a very good sealing of the rolling area is achieved, namely via the function of the contacting sealing lip. It is associated with the dust gap with the outer ring positioned dust lip, such that between the two a circumferential annular channel is formed, which acts as a grease or lubricant receiving space. In this always a sufficient amount of lubricant is included, so that in the sensitive contact area between the sealing lip and ring always a sufficient lubrication is possible. On the one hand, therefore, a very good seal is taken care of, and on the other hand, a lubricant outlet from the relevant area is prevented.
  • the sealing element itself expediently has a carrier ring on which a circumferential sealing section having the sealing lip and the dust lip is arranged.
  • This sealing portion preferably made in one piece, is molded from a corresponding elastomeric material and the metal carrier ring in a simple manner.
  • the carrier serves to stabilize as well as the easier assembly of the sealing element on the plate spring respectively the spring-sealing ring combination on the sleeve.
  • On the support ring may further be formed a holding portion, by means of which the sealing element is arranged on the plate spring.
  • a holding portion by means of which the sealing element is arranged on the plate spring.
  • the plate spring advantageously has a circumferential receptacle in which the holding portion is added.
  • This recording can, for example, be rectangular in cross-section, it is axially limited by a simple radial flange. If the holding section is also rectangular in cross-section, a sufficient positive fit can be achieved, so that the sealing element, respectively the holding section, is tensioned against the inner ring, for example via the plate spring.
  • Other attachment possibilities of the sealing element on the plate spring are of course conceivable. For example, it is conceivable to provide on the plate spring a circumferential radial projection, which engages in a corresponding, seen in cross-section U-shaped holding etc.
  • the sealing element which is arranged as described on the disc spring, also secure and avoid that it comes to a relative movement between the sealing element and plate spring respectively sealing element and the strained on the diaphragm spring ring due to the contact of the sealing lip on the other ring is expediently the sealing element by means of Disc spring clamped on the clamped over the plate spring inner or outer ring also so, for example, is also spring-loaded against the inner ring.

  • the inner ring 4 is tensioned.
  • the inner ring 4 has an inwardly drawn radial flange 7.
  • the sleeve 6 has a circumferential holding portion 8, which has a end-side radial deflection 9, which serves as an abutment for a plate spring 10, via which the inner ring 4 is clamped with its radial flange 7 against a radial portion 1 1 of the sleeve 6.
  • a sealing element 12 is fixed in the region between the outer ring 3 and a likewise radially inwardly drawn radial flange 13 and the radial flange 7 of the inner ring on the plate spring 10.
  • This sealing element 12 consists of a carrier ring 21, for example a metal ring, on which a sealing portion 14 of a corresponding elastic material, usually an elastomer, molded, preferably molded.
  • This sealing portion 14 comprises on the one hand a contacting sealing lip 15, which is thus in touching contact with the radial flange 13 of the outer ring.
  • the sealing portion 14 further includes a dust lip 16, which also runs at a small distance to the radial flange 13 out.
  • the contacting sealing lip 15 is located radially on the outside and the dust lip 16 is arranged radially on the inside. Both are in a V-shaped configuration to each other, so that between them seen in cross-section, a V-shaped um- running annular channel 17 forms, which serves as a receiving reservoir for lubricant, usually grease, which serves to lubricate the touching adjacent sealing lip 15.
  • lubricant usually grease
  • the rolling region that is to say the region in which the rolling bodies 5 roll between the rings 3, 4, is sealed by way of this sealing lip 15, so that the entry of dirt is prevented here.
  • a permanent lubrication in the sealing lip area is ensured by the combination of sealing lip 15 and dust lip 16, since over the circumferential annular channel 17 is always a sufficient volume of lubricant available.
  • a portion 18 is further arranged, which is preferably made of the same elastomeric material as the sealing portion 14. So he is also molded, preferably molded. He is located radially inward.
  • the plate spring 10 has for this purpose a circumferential receptacle 19 which, seen in cross-section, is rectangular and, viewed axially, is delimited by a radial flange 20.
  • the holding portion 18 is formed complementary in shape, so fits positively into the receptacle 19 a.
  • the axial length of the holding portion 18 is dimensioned such that in the mounting position of the holding portion 18 and via it the sealing element 12 is clamped tightly against the radial flange 7 of the inner ring 4.
  • the inner ring 4 is braced on the sleeve 6 via the plate spring 10, it is of course also conceivable to clamp the outer ring 3 on the sleeve 6 with a reverse configuration, to which a disc spring also serves.
  • the sealing element 12 is fixed on the plate spring and is clamped against the outer ring, consequently, the sealing lip 15 and the dust lip 16 would seal to the inner ring.
