Description

  • The present invention relates to a clutch disc for a friction clutch of a motor vehicle having at least one non-rotatably engageable with a transmission input hub, at least one friction lining in a radially outer region of the clutch writing, wherein the Reibbelagsebene is substantially orthogonal to NEN rotational axis, and a drive plate with which the lining rotatably is connectable to the hub, wherein further at least one spring device is provided with which the drive plate with respect to the axis is elastically centered, so that the friction lining and / or the drive plate can be arranged substantially perpendicular to the hub axle.
  • In vehicle construction, the problem arises, in particular with transversely installed drive units, that a transmission input shaft is no longer mounted in a pilot bearing in the crankshaft and is therefore centered with respect to the crankshaft. The consequence of this is that small axial offsets, and wobbling movements can occur during operation, which are induced by the non-circular running of the crankshaft or of the flywheel fixed thereto.
  • When using rigid clutch plates, in which the friction linings are substantially rigidly coupled to the hub of the clutch disc, caused by the axial offset or the wobble also the problem of excessive wear in the hub profile or the transmission input shaft profile or there is the problem that the welding or caulking between the hub and the friction disc bearing drive plate breaks. In addition, the axial engine vibrations are passed freely into the transmission input shaft.
  • In order to control such axis offsets, Achsverkippungen and wobbling movements, clutch discs of the type mentioned were developed, which can perform the said radial movement and tilting movement.
  • For example, in the DE 19926382 or the DE 2948765 , has been proposed to center the driving plate by means of spring elements, wherein the spring elements are fastened as a separate spring elements by means of bolts on the driver, or the drive plate itself is resilient. In this case, the spring element either one-sided, see DE 2948765 or two-sided, see DE 19926382 be tense.
  • However, the solutions of the prior art have several disadvantages. On the one hand, the solution of the biased plate spring has the disadvantage that not enough movement between the drive plate and the hub can be realized. On the other hand, a two-sided tensioned and spring-trained drive plate, as shown in DE 19926382 known, technically difficult to implement because of the material of the spring tongues other requirements are made than to the drive plate itself.
  • In addition, in the known embodiments, the stiffness of the suspension can not be set arbitrarily and the degrees of freedom of the Taumelweichheit are limited. In shared Belagkranzanbindungen also creates a very high clearance, especially under the influence of speed, so that the known designs are limited in the existing space to 250 Nm engine torque.
  • Object of the present invention is therefore to improve the disadvantages of the prior art.
  • This object is achieved by a clutch disc according to claim 1.
  • The invention is based on the idea of providing a clutch disc for a friction clutch in which a driver disc is non-rotatably connectable to the hub, said driver disc having on both sides of a plate spring which elastically centered the driver disc with respect to the axis. In this case, the plate spring is supported on the one hand on the drive plate and on the other hand on the hub.
  • The inventive use of disc springs, which are arranged on both sides of the drive plate, on the one hand has the advantage that the two-sided arrangement of the plate springs allows greater mobility between the drive plate and hub.
  • On the other hand, a more defined spring stiffness than with the leaf spring design can be achieved with the plate spring, whereby a better centering depending on the application, especially at high engine torques is possible. For example, a plate spring in the radially inner and / or radially outer region with a plurality of circumferentially distributed radial slots can be performed. In addition, the materials for the spring device or drive plate can be optimally selected because of the materials no combined requirements such as spring property and good torque transmission must be provided.
  • According to a preferred embodiment of the present invention, the plate spring is supported on the hub by means provided in the hub groove in which the hub-side end of the plate spring is latched. Although the production of a groove in the hub is relatively complex, but the installation is significantly simplified, since the plate spring must be engaged only in the groove. This eliminates the costly attachment of the spring element by means of bolts, as shown in DE 19926382 is known. The groove may be formed as an annular groove, but it is also possible to provide only groove-shaped recesses in the hub, which are adapted to receive a spring tongue of the plate spring, when the plate spring has such a design.
  • According to a further preferred embodiment, the plate spring is supported on a hub flange formed on the hub. This hub flange forms a contact shoulder for the plate spring and has the advantage that the hub flange can be formed together with the hub, so that the additional step of producing a groove is eliminated. Advantageously, the hub flange and the hub can be made simultaneously by sintering or cold extrusion.
  • According to a further advantageous embodiment, the plate spring is supported on one side by means of a hub flange, while engaging in a groove at the other end. This is particularly advantageous if provided on one side increased spring stiffness or if the mobility to the engine or transmission side to be limited or kept free.
  • According to a further preferred embodiment, the hub flanges may be annular, but it is also possible to attach circumferentially distributed individual hub flange elements.
  • According to a further preferred embodiment, hub flanges are formed on both sides of the drive plate as abutment shoulders for the disc springs, wherein the shoulders are arranged in particular alternately. The alternately arranged abutment shoulders have the advantage that during assembly of the clutch disc, the drive plate can be attached to the hub and the plate spring must be pressed only at some places behind the abutment shoulder. In addition, this hub can be manufactured in a single manufacturing step by sintering or cold extrusion.
  • Advantageously, the abutment shoulders are arranged such that starting from the foot of the abutment shoulders in the direction of the driver disc no area is present, which has a larger diameter than the foot of the abutment shoulder. This means at the same time that there is no undercut, which would have to be produced by a subsequent processing step, so that such a hub can also be produced by cold extrusion.
  • According to a further advantageous embodiment, the drive plate radially inward on an internal toothing, which meshes with an external toothing on the hub under Providence of a Radialbewegungsspiels.
  • It is also advantageous if a torsional backlash between hub and drive plate is present, wherein the torsional backlash is limited to a range of less than 5 °, in particular 1 ° to 3 °. This torsional backlash causes further parts, such as a pad ring and its connection, are not claimed during tumbling movements of the clutch disc.
  • According to a further advantageous embodiment, the teeth of the drive plate half as many teeth as the hub teeth, which in particular can be used for alternately arranged abutment shoulders, the teeth of the drive plate through the opening in the abutment shoulders in the hub teeth.
  • In this case, the abutment shoulders may be formed in the area of the tooth base and / or the tooth heads, wherein it is particularly advantageous if the abutment discs on the tooth base and on the other side of the driver disc, the abutment shoulders are arranged on the tooth tips on one side of the drive plate. This allows in particular a simplified assembly.
  • According to a further preferred embodiment, at least one friction ring is provided between the plate spring and the drive plate. As a result, since the spring rubs against the hub disc or the friction ring during wobbling, this friction can be optimized in size. A defined friction can also be defined on the outside diameter and the bearing surface of the plate spring on the drive plate or the friction ring. Instead of a friction ring, a defined friction can also be provided via a coating attached to the plate spring and / or the drive plate.
  • According to a further preferred embodiment, the inner diameter of the hub disc is greater than the outer diameter of the hub in the region of the abutment shoulders, so that the teeth of the drive plate can have as many teeth as the hub teeth. This is particularly advantageous when high torques are to be transmitted, since the force effect can be distributed over a plurality of drive disc teeth.
  • According to a further preferred embodiment, the disc spring is provided with spring tongues which extend radially inward, the number of which preferably corresponds to the number of teeth of the hub teeth. This embodiment of the plate spring also allows a simplified installation and also an adjustment of the spring stiffness of the plate spring.
  • Preferably, the spring tongues and / or spring tongue interspaces are dimensioned such that they do not correspond to the interdental spaces of the hub teeth even during rotation and thus cause a loosening of the plate spring by itself. This means that the spring tongue interspaces, in particular at contact shoulders which are formed on the tooth tips, are designed to be significantly smaller than the spring tongues, so that it is ensured that the plate springs are supported even with the expected torsional backlash on the abutment shoulders of the hub.

  • In the following, identical or equivalent components are identified by the same reference numerals.
  • 1 shows a schematic partial view of a first embodiment of the clutch disc according to the invention 1 with a transmission input shaft 2 in a hub 4 runs, wherein the transmission input shaft 2 and the hub 4 engage with each other via not shown teeth here. On its outer surface, the hub points 4 a gearing 6 on, in which a gearing 7 a drive disc 8th intervenes. The driving disc 8th is by means of a bolt 10 with a pad spring 12 connected to the friction linings 14 wearing.
  • At the hub end of the drive plate 8th are on both sides of the drive plate 8th two spring elements 16 . 18 arranged at its one end to the drive plate 8th and at the other end at the hub 4 support.
  • In this case, the support of a spring element 18 at the hub 4 about one in the hub 4 trained groove 20 realized, in which the spring element 18 engages on the hub side. The other spring element 16 rests on one at the hub 4 trained hub flange 22 from.
  • The two sides of the hub 4 arranged spring elements 16 . 18 allow an elastic centering of the drive plate 8th , so that a good Taumelweichheit arises.
  • At the in 1 illustrated embodiment may advantageously the spring stiffness of the spring elements 16 and 18 be formed differently. Since in particular the spring element 16 must not be designed to engage in a mounting in a groove, the spring stiffness of the spring element 16 be higher.
  • As a result, a clutch disc can be produced whose mobility is specifically limited to the engine or transmission side (in the case shown, to the transmission side).
  • As in 2 shown, instead of the support on the hub flange 22 can also be provided that the second spring element 16 also in a groove 24 in the hub 4 is formed, is supported. Unlike the in 1 illustrated embodiment is in the in 2 illustrated embodiment, the spring stiffness of the spring elements substantially the same. Thereby, a uniform tumbling softness of Clutch disc be provided both on the engine side and on the transmission side.
  • 3 shows a further preferred embodiment of the clutch disc according to the invention, but in which it is provided that the spring elements 16 . 18 on two flanges 22 . 26 support. The hub flanges 22 . 26 are formed in this embodiment as investment shoulders, alternately on both sides of the drive plate 8th are arranged. Here are the contact shoulders 22 . 26 at the base of the tooth 32 the hub toothing 6 arranged.
  • 4 shows a perspective view of such a hub 4 in which the abutment shoulders 22 . 26 are formed alternately on the tooth base. As can be seen from this figure, the hub has 4 radially inside an internal toothing 28 on, with which they can engage with the teeth of the transmission input shaft. Radially outward, the hub has the external teeth 6 on that with the internal teeth 7 the drive disc 8th engages. The external toothing 6 has tooth heads 30 and tooth reasons 32 on, with Mitnehmerscheibenseitig alternately on the tooth base 32 the plant shoulders 22 . 26 are formed.
  • To the drive disc 8th as easy as possible on the hub 4 aufzustecken, are the teeth of the drive plate 8th Corresponding to every second tooth reason 32 the hub 4 formed (see arrow). In this case, the inner diameter of the drive plate 8th correspond to the outer diameter D N of the hub in the tooth roots.
  • However, a radial clearance between hub teeth 6 and drive plate gearing 7 To ensure it can be advantageous to the inner diameter of the drive plate 8th slightly larger than the outer diameter D N of the hub in the area of tooth roots 32 to choose.
  • Alternatively, the teeth of the drive plate 8th Also have such a large inner diameter that this larger than the outer diameter D A of the hub 4 in the area of the abutment shoulders. This allows the drive plate 8th over the investment shoulders 18 slide and with their teeth every tooth reason 32 intervention.
  • This embodiment also has the advantage that due to the remaining due to the larger inner diameter gap between Mitnehmerscheilenzahnkopf and tooth root of the hub 4 at the same time a radial play of the drive plate 8th at the hub 4 given is.
  • When installing, depending on the embodiment, for example, only the plate spring 18 on the hub 4 stuck, with the plate spring 18 radially inward on the contact shoulder 26 is present or in the groove 20 is engaged. Subsequently, the drive plate 8th on the hub 4 stuck and with the second plate spring 16 braced. This biasing is also done by snapping the diaphragm spring 16 in the groove 24 or behind the contact shoulder 22 , At the same time learns but also the first disc spring 18 a bias, leaving the drive plate 8th pre-tensioned on both sides.
  • For trouble-free installation of the disc springs 16 . 18 to ensure the disc springs can 16 . 18 radially inside have spring tongues. At the in 3 and 4 shown embodiments in which the abutment shoulders 22 . 26 in the area of the tooth base 32 are arranged correspond to the spring tongues 34 preferably with the tooth reasons 32 while the spring tongue gaps 36 with the tooth heads 30 correspond.
  • Instead of the tooth base 32 arranged abutment shoulders 22 . 26 can the investment shoulders 22 . 26 also on the tooth heads 30 the hub 4 be arranged. At the tooth heads 30 trained aniseed shoulders 22 . 26 , must be in the design of the diaphragm spring 16 . 18 with spring tongues 34 be taken to ensure that the dimensioning of the spring tongue gaps 36 not too large, so that the diaphragm spring 16 . 18 in a torsional backlash not with the abutment shoulders 22 . 26 out of engagement. It is therefore advantageous if the spring tongue gaps 36 significantly smaller than the spring tongues 34 are dimensioned. Such a plate spring 16 . 18 is in 6 shown.
  • 7 shows a further preferred embodiment of the clutch disc according to the invention, in which, however, the abutment shoulders 22 on one side of the drive plate 8th at the teeth heads 30 and the investment shoulders 26 on the other side of the drive plate 8th on the tooth reasons 32 are formed.
  • In such an embodiment, it is advantageous to have two differently shaped disc springs 16 ; 18 to use, with the plate spring 16 that attach to the on the tooth grounds 32 trained investment shoulders 26 supports, for example, a in 5 has shown shape while the plate spring 18 that attach to the on the tooth heads 30 trained investment shoulders 26 supports, for example, a in 6 has shown shape.
  • No matter if the shoulder contact 22 . 26 on the tooth head 30 or at the base of the tooth 32 is arranged, the great advantage of this design is that the Hub can be produced in a single manufacturing step, wherein the abutment shoulders are mitgefertigt directly in the production of the hub. This means that aftertreatment, in particular, a rotary treatment for forming a groove, is omitted, which in turn the manufacture of the hub 4 simplified and cost-effective.
  • Preferably, the abutment shoulders 22 . 26 also arranged such that starting from the foot of the abutment shoulders in the direction of the hub disc no area is present, which has a larger diameter than the foot of the abutment shoulder. This means at the same time that there is no undercut, which would have to be produced by a subsequent processing step. This is particularly important if the hub is manufactured by cold extrusion, as undercuts are not feasible in this process. While undercuts are indeed manufacturable during sintering, the shape of these undercuts is very limited.
  • All embodiments of the clutch disc according to the invention is common that over appropriate dimensioning of the internal teeth 7 the drive disc 8th opposite the external toothing 6 the hub 4 a torsional backlash between hub and drive plate can be achieved. In this case, this torsional backlash is preferably in a Verdrehwinkelbereich between 1 ° and 3 °, which corresponds approximately to the Verdrehwinkelbereich a conventional idler damper. However, since the disc springs 16 . 18 also because of their support on the drive plate 8th rub, can be dispensed with the torsion spring.
  • 8th shows a further embodiment of the clutch disc according to the invention, in which between the disc springs 16 . 18 and the drive disc 8th one friction ring each 38 is arranged. At this friction ring 38 lie the disc springs 16 . 18 at. About the size of the contact surfaces of the disc springs 16 . 18 and / or the friction coefficient of the friction rings 38 the friction can be adjusted and optimized.
  • Instead of the friction rings 46 . 48 can also have a corresponding coating of the disc springs 16 . 18 or the drive plate 8th be made, which also provides an adjustable friction.
  • As described above, it is advantageous to form the form-locking hub connection as a toothed plug-in connection, in which the drive plate is held in position on both sides by one or more spring elements. The toothing clearance provided not only allows an axial degree of freedom, but also a wobble softness of the hub to the drive plate, which further parts of the clutch disc, such as lining ring and its connection, are not claimed. The assembly according to the invention is carried out by joining with the hub and the drive plate, which are then stretched with the spring element until it engages the plate spring.
