- joint bodies are known from the prior art and disclosed, for example, in DE 37 34 089 A1.
- this document describes an elastic joint body in which collars are pressed in the axial direction for axial support of the loop packages.
- the collars have an L-shaped profile and are axially immovable and non-rotatable by pressing
- support elements are provided around the bushes around.
- the support elements are immovably and rotationally fixed connected to their associated socket and extend perpendicular to the central axis of the socket. 5
- DE 104 40 854 A discloses a flexible disc in which the filament wound around each two adjacent coil-like body.
- the equiaxed coil-like bodies are seated on a bush whose flanged edges hold mudguards. In order to prevent spreading of the cover plates of the bobbin, o these are curved.
- the individual thread windings are connected to one another in such a way that the convex curvatures of the cover disks point outward, so that the abutting cover disks of the coil bodies are concavely arched and support one another at their outer edge. 5
- US 1,531,999 A US Pat.
- EP 1 302 686 A2 and EP 1 469 218 Al show elastic joint bodies in which bushes are looped around by Schiingen packages. which, however, lags behind the documents described above in their relevance.
- the support elements are first pressed onto the jacks and then wrapped the Schiingenaftere on the jacks.
- the manufacturing process for the above known from the prior art joint body is therefore relatively expensive.
- the support elements must be pressed onto the bushes to then bring the Schiingene in the areas between two support elements or to be able to wrap.
- an elastic joint body of the type described in which the support means has two attachable to one of the bushes, axially outer collar elements, at least two of the create Schiingename leading, between these Schiingenveren at least one axially inner substantially level intermediate disc is provided on one of the bushes, which is arranged at an angle oblique to the central axis of the bushing.
- the term "outlet area” is understood to mean the area in which the loop packages run from one bushing in the direction of the next bushing wrapped around them. Due to the improved load capacity of the thread packages, larger overall torques can be transmitted with constant dimensioning.
- the elastic joint body can be built smaller dimensioned with constant torque absorption.
- space can be saved in a drive train of a motor vehicle.
- the obliquely arranged on the sockets of the joint body according to the invention slices arranged the different forces claimed Schiingenmus of train and pressure path effectively separated, so that friction effects between the Schiingen iten from lo the same materials can be avoided.
- the manufacturing process can be significantly simplified and accelerated by the elastic joint body according to the invention compared to the manufacturing process of the known from the prior art joint body, since the step of i5 pressing the inner support elements is omitted on the bushings in the joint body according to the invention. Rather, the washers are placed with play on the respective socket and align themselves during the manufacturing process in optimal skew. A targeted positioning in a desired position during the injection molding with elastomer is not required. Also, no need
- the at least one washer with such a game on the bushing angeord- 5 net is that it assumes an angle on the socket, with which it is inclined to the axis of one of the sockets.
- the radial clearance between a central opening of the intermediate disk and the outer peripheral surface of the associated bushing is in the range from 0.01 mm to 1.5 mm, in particular from 0.05 mm to 0, 1 mm.
- the play between the bushing and the at least one intermediate disk arranged on this bushing is designed, for example according to the invention, in such a way that Before the vulcanization, the washers are ideally inclined to the central axis of the associated bushing.
- the inclination of the intermediate disks between the individual Schiingenpakten is fixed during vulcanization with elastomer, and thus pers pers pers for the entire life of the Gelenkkör- invention, with displacements of the elastomer are performed about at cardanic stress on the joint body with.
- resulting from the inclination of the intermediate discs sections increased compression of the Schiingen ite.
- the at least one intermediate disc is integrally formed with the associated bush, wherein the intermediate disc is at an angle oblique to the central axis of the bushing having. This also allows the desired support effects in the outlet area of the Schiingenwovene reach.
- each bushing is surrounded by three Schlingenpa- keten, wherein a middle Schiingenb two axially inner intermediate discs are assigned, which are arranged at an angle oblique to the central axis of the bush, and wherein between the axially inner intermediate discs and the axially outer collar elements two Schiingene are provided.
- the two intermediate discs are also at an acute angle to each other, that is, they do not run parallel to each other.
- the Schiingenb between the two axially inner intermediate discs is loaded to train, whereas the two axially outer Schiingene between the axially inner intermediate discs and the axially outer collar elements are subjected to pressure.
- This embodiment of the invention provides that the axially inner intermediate discs extend at an angle to the axis of the associated sleeve, that they approach each other in the outlet region of the outer Schiingenwovene and to the nearest to them the axially outer collar elements.
- the axially inner intermediate discs in the peripheral region of their associated bushing continuously reduce the cross section of the axially outer loop packets and the middle loop packet in the direction of the next loop wrapped around by the respective loop package.
- the axially outer pressure-loaded Schiingenwovene lo are continuously compressed by the axially outer collar elements and the axially inner shims to their respective outlet area, whereas the middle loaded train on Schiingenb is continuously compressed by the two axially inner shims in the outlet area.
- the largest compression of the loop packages is always at the outer edge section of the intermediate disks.
- the washers 2o are formed rigid. This can be achieved by suitable choice of material and dimensioning.
- the axially outer collar elements are fixedly connected to one of the bushings, in particular by pressing.
- the axially outer collar elements may have a collar shape, a U-shape, an L-shape or a disc shape.
- the invention further relates to a shaft assembly having an elastic joint body described above.
- FIG. 1 is a perspective view of a bushing with a support device according to the invention
- Figure 2 is a front view of a socket with a support device according to the invention.
- 3a, 3b are perspective views of a socket with the inventive support means and supported by this Schiingeneveren;
- Fig. 4 is a plan view of a bushing with the support means.
- Fig. 5 is a sectional view of the support means along the section line IV-IV of Fig. 4 and
- Fig. 6 is a partially cutaway plan view of a joint body according to the present invention.
- FIG. 1 shows a perspective view of the support device 10.
- the support device 10 is arranged on a bushing 12 and comprises two axially outer collar elements 14, 16 and two axially inner intermediate discs 18, 20.
- the outer collar elements 14, 16 are fixed to the bush 12 applied by press fit. It can be seen in Fig. 1 further that the intermediate discs 18, 20 extend obliquely to the central axis M of their associated bush 12.
- Fig. 2 shows a front view of the support means 10, from which in turn the outer collar members 14, 16 and the inclined axially inner intermediate discs 18, 20 recognizes.
- the axially inner intermediate discs 18, 20 are arranged with such an inclination to the central axis M of the bushing 12 that they approach each other in some areas to each other and on the other at their opposite portion to the nearest them to the axially outer collar elements 14, 16 approach.
- the intermediate discs 18, 20 are formed with a central opening through which the bushing 12 extends.
- the central opening is dimensioned larger than the outer diameter of the bush 12.
- the central opening may also be elliptical.
- the inclined washers 18, 20 can also be formed integrally with the bush 12.
- FIGS. 3 a and 3 b show perspective views of the support device 10 with the loop assemblies 22, 24 and 26 guided and supported by the support device 10.
- Figures 3a and 3b show that the thrust loaded outer loop packages 22 and 26 are guided between the axially outer collar members 14, 16 and the intermediate discs 18, 20, i. the Schiingenb 22 between the outer collar member 14 and the washer 18 and the Schiingend 26 between the collar member 16 and the washer 20.
- the middle loaded on train Schiingentext 24 by the two obliquely to the central axis M of the bushing 12 extending washers 18, 20 led. Prevent the washers 18, 20, which rub the Schiingene each other.
- the largest compression of the Schiingenwovene 22, 24, 26 is thus in each case at the outer radius of the intermediate discs 18, 20 before.
- the intermediate disks 18, 20 reduce the cross section of the outer pressure-loaded loop packages 22, 26 in cooperation with the outer collar elements 14, 16 to the outlet region, whereas the cross section of the loop package 24 loaded with tension is only limited by the inclined position the intermediate discs 18, 20 is specified.
- the intermediate discs 18, 20 and the bushes 12 are designed with such a game to each other that they are in the Production of the joint body, ie, during the positioning of the Schiingenwovene 22, 24, 26, before the vulcanization oblique to the central axis M of the bushes 12.
- the two washers 18, 20 are pushed onto the bushing 12, whereupon the intermediate discs 18, 20 make obliquely through the game.
- the intermediate discs Due to the play between the intermediate disc 18, 20 and the bushing 12, the intermediate discs are movable on the bush, whereby the intermediate discs 18, 20, to some extent according to various factors, such as material hardness of the Schiingename and the number of filament windings of the individual Schlingenpa- kete, adapt or freely adjust.
- the Schlingenpake- te 22, 26 are pushed onto the socket 12.
- the inclination of the intermediate discs 18, 20 is permanently fixed by the elastomer composition, that is "frozen" in the elastomer composition.
- the Schiingenwovene 22, 24, 26 thus experience a recognizable in Figs. 3a and 3b continuous compression in the outlet region A of the bushing 12, i. in the direction of the next of the respective Schiingenzig 22, 24, 26 looped socket. Due to this continuous compression of the loop packs 22, 24, 26 in the region in which the loop packs 22, 24, 26 run out in the direction of the next bush 12 to be wrapped around, a self-optimizing support effect results. This means that it is precisely this region of the loop packs 22, 24, 26, which is heavily loaded during cardanic stresses, that is reinforced by the increased compression of the loop packs. This support effect makes it possible to harmonize the specific loading of the individual thread windings of the loop packs 22, 24, 26.
- the compression of the loop packs 22, 24, 26 makes the region in which the loop packs 22, 24, 26 have the greatest forces , the most reinforced. Furthermore, looping packages 22, 24, 26 with a larger number of thread windings can be used by the section-wise compression of the loop packages 22, 24, 26 by means of the intermediate disks 18, 20, whereby the service life and the torque absorption of the joint body can be increased.
- FIG. 5 shows that the intermediate discs 18, 20 separate the differently loaded ski packages 22, 24, 26 from each other and avoid frictional effects between the shoe packages 22, 24, 26 of the same materials.
- FIG. 6 shows a partially cut-away plan view of an elastic joint body 30 according to the invention with six bushes 12 surrounded by a rubber-elastic casing 32.
- the bushes 12 are arranged in the circumferential direction with respect to a central axis M at predetermined angular intervals of the joint body 30.
- the collar elements 14 on the bushes 12 which are arranged for the axial support of the Schiingenwovene 22.
