Definitions
- the invention relates to an elastic joint body with at least one Schlingen genbyte, at least two bushes which extend transversely through the Schiingendes, collars which are mounted on a respective bushing end to axially support the Schiingenang on the respective sleeve, and a rubber-elastic sheath, in which the Schiingenb and the socket are at least partially embedded.
- Such elastic joint body for example in the form of joint discs for gimbal connection of waves, especially in the drive train of motor vehicles, is common.
- a joint body bushings by means of threaded bolts, rivets or the like inserted through them. at Wellenflan- see or the like. attached.
- an elastic joint body in the form of a joint disc in which a plurality of Schiingene are joined together overlapping each other to form a ring and held together by cylindrical bushings which are inserted through the overlapping areas of the Schiingene.
- the ski packages are fixed in the axial direction by pressing on each bushing end a collar before the entire assembly is placed in a vulcanizing mold, in which it receives its rubber-elastic casing.
- the collars are metal rings of L-shaped profile, which are not only axially immovable by pressing on one end of the bushing but also rotatably connected to the socket.
- the bushings In order to prevent the bushes, together with the collar mounted on them, being twisted when tightening screws used for mounting the flexible disk, thereby completely or partially destroying the adhesive bond between the bushings and the looping packages surrounding them and the surrounding rubber, the bushings have one end at least one sharp-edged projection which is hard enough to press in tightening the associated fastening screw in an associated shaft flange or the like.
- the sockets are here designed as collar bushes, each with a socket part and one integrally formed thereon first collar and a locking arrangement at the end remote from the first collar of the socket part. With this locking arrangement forms a complementary locking arrangement on a second collar an axially and rotationally fixed snap connection.
- Both collars have axially parallel holes into which the rubber-elastic casing penetrates during vulcanization, so that the collars, and with them also the bushing parts, are firmly anchored.
- the invention is based on the problem that wave strands containing one or more elastic joint body of the type described, in a statistically relevant number of cases have so far inexplicable deviations from the expected torsional vibration behavior and also their normally expected life in spite of the measures described above not to reach.
- the invention is based on the recognition that such deviations can arise from the fact that when installing inventive joint body in a Weistle strand occurring slight and therefore hitherto considered irrelevant twisting of individual or all bushings and the associated collar cause that one or the other with Rubber coated Schiingenb biased in an unplanned way and the affected elastic joint body is consequently unevenly loaded during operation.
- the object is achieved according to the invention, starting from an elastic joint body of the type described above in that the areas of the sockets left free by the collar, embedded in the envelope are smooth and the collars are snapped onto the associated socket with such play that the Socket is rotatable within the collar while they are firmly connected to the enclosure.
- each socket can turn as easily as possible in the collar fixed immovably on it in the axial direction, if it is exposed during the assembly of the elastic joint body, in particular when tightening a fastening screw, a torque.
- the smooth design of the outer jacket surfaces of the bushings which are released from the collars, prevents a rotating bushing from causing any appreciable tension in a loop bundle that wraps around it.
- the free rotation of the sockets within their collars also prevents a document from being transferred from a rotating bushing to an associated collar, which could lead to a tensioning of the regions of the elastic covering which abut against the collar.
- FIG. 4 an assembly of FIG. 2, greatly enlarged, FIG. 4, the detail IV in FIG. 3, further enlarged,
- Fig. 5 shows a corresponding section of the assembled assembly
- Fig. 6 is a development of Fig. 5 and
- FIG. 7 shows a modification of FIG. 6.
- a joint body 10 is shown in the form of a joint disc, which is intended to connect two waves in the drive train of a motor vehicle with each other.
- the joint body 10 contains six loop packages 12, which each loop around two bushings 14 in such a way that adjacent loop packages intersect each other.
- the bushings 14 are arranged at equal distances from one another around a central axis A and are provided with two raised collars 16 each.
- the entirety of the string packages 12 as well as substantially the bushings 14 and parts of each of the collars 16 are embedded in an elastic wrapper 18 of vulcanized rubber.
- a cylindrical inner bush 20 made of steel is press-fitted.
- the bushes 14 are made of plastic, preferably high-performance thermoplastic, which can be exposed to a service temperature of at least 180 ° C. is inherently flame retardant, has high hardness and stiffness, has a very low creep even at elevated temperatures, is resistant to chemicals and very little hygroscopic, has a high tensile and flexural modulus of elasticity, and has a high creep strength in conjunction with the indented inner liner 20 - shows.
- plastic with a tensile E modulus according to ISO 527 part 1 and 2 of at least 14000 MPa, a compressive modulus according to ISO 604 of at least 15000 MPa and an elongation at break according to ISO 527 parts 1 and 2 of about 1 is suitable , 9%.
- the plastic used should have the lowest possible tendency to adhere to the rubber of the elastic sheath 18.
- the cylindrical outer surfaces of the bushes 14 are preferably polished.
- the collars 16 are made of a plastic whose properties are similar to those of the bushings 14, except that the plastic used for the collars 16 preferably has sufficient elasticity for joining with the bush 14 and good adhesion to the elastomer of the elastic wrapper 18.
- 16 is plastic for the collar with a tensile strength according to DIN 53455 of 200 Mpa and an elongation at break according to DIN 53455 of 3.9%.
- All sockets 14 are equal to each other; they each have two identical bushing ends 22 and an intermediate cylindrical bushing body portion 24.
- Each bushing end 22 has a flat annular end surface 26; This is followed by a first cylindrical section 28, the diameter of which is appreciably smaller than that of the bushing main part 24. This is followed by a likewise cylindrical recess 30, through which the diameter of the bushing end 22 is further considerably reduced.
- the recess 30 is delimited against the first cylindrical portion 28 by a normal to the bushing axis B first shoulder 32 and passes at an axial distance from this in a conical surface 34 whose diameter increases with increasing distance from the first shoulder 32.
- the conical surface 34 terminates at an axial distance from a second shoulder 36; the gap between this and the end of the conical surface 34 is bridged by a second cylindrical portion 38 whose diameter coincides with that of the first cylindrical portion 28.
- Each of the collars 16 has an inner profile complementary to the outer profile of the bushing ends 22 which is dimensioned such that a collar 16 can be snapped onto each bushing end 22 in the manner shown in FIGS. 5 to 7, such that between the outer profile of the bushing end 22 and the inner profile of the collar 16 is only a minimal axial clearance, but a radial clearance, the before the Pressing the inner sleeve 20 in the socket 14 is so considerable that even then a noticeable game remains when the inner sleeve 20 has been pressed into the socket 14, with all the diameter of the bushing 14 have increased slightly.
- the thus remaining radial and axial play between each of the bushing ends 22 and the latched collar 16 provides assurance that the bushings 14 are rotatable within the collar 16 and remain so throughout the life of the joint body 10.
- the inner bushings 20 are preferably first pressed into the sockets 14 made of plastic only when the joint body 10 has been completed by vulcanization of the elastic sheath 18 and subsequent deburring, moreover.
- This has the advantage that joint bodies 10 are batch-frozen, then deburred in a rotating drum and finally brought back to ambient temperature and allowed to dry before the inner sleeves 20, which are generally made of stainless steel, are pressed in.
- a ring seal 40 can be arranged around the two end faces 26 of each of the bushings 14, namely either end-wise on the collar 16 according to FIG. 6 or in the gap between the collar 16 and the first cylindrical one according to FIG Section 28 of the respective bushing end 22. In both cases, can be prevented with such ring seals 40 that in the operation of the joint body 10 dirt in the gap between the collar 16 and the sleeve ends 22 penetrates and thereby complicates the rotation of the bushes 14 within the collar and the Widening of the connection leads.
- the collar 16 may be provided in the usual way with axially parallel holes 42 which ensure the vulcanization of the elastic sheath 18 that sufficient rubber penetrates into the space between paired collars 16.
- the holes 42 also improve the firm adhesion of the collars 16 to the elastic wrapper 18. Peel-off of the elastomer at high speeds is thereby counteracted.
- All described embodiments of the joint body 10 have in common that its reinforcement due to low density of the reinforcing materials have a low inertial mass. As a result, occurring at a given allowable eccentricity of the arrangement of the reinforcement (Schiingenwovene 12, jacks 14, collar 16) occurring Urun imbalance of the joint body 10 is low.
- the measures described also make it easier to recycle the materials of the joint body 10: After pressing out the inner sleeves 20 made of steel, the joint body 10 due to the similar material properties of its other components (elastomer, thread, Kunststoffarm réelle) by grinding, shredder or the like Shredding processes recyclable. Conventional flexible discs with steel reinforcement, however, are only pyrotechnic disposable.
