Description

Technical Field

[0001] The present invention relates to a coupling device, in particular for a vehicle drive. In particular, the present invention relates to a coupling device for a rail vehicle drive. Furthermore, the present invention relates to a wire-reinforced coupling element for such a coupling device. Furthermore, a bogie for a rail vehicle and a rail vehicle form the subject matter of the present invention. Summary of the Invention

[0002] The object of the present invention is to provide a coupling device of the type mentioned at the outset which makes optimal use of the installation space available in the radial direction, requires little installation space in the axial direction and can absorb large deflection angles.

[0003] A coupling device for a vehicle drive device comprises:

[0004] at least one first coupling element, said first coupling element having at least one first wire reinforcement connection device, wherein said first wire reinforcement connection device has at least one wire package, said wire package being embedded in at least one elastomer,

[0005] Therein, the at least one first coupling element has at least one supporting device, which is connected to the first wire reinforcement connecting device, wherein the at least one supporting device supports the first wire reinforcement connecting device in a radial direction.

[0006] Due to the support device, the number of coupling planes of the first coupling member and / or the second coupling member is increased. Due to the support device, the first coupling member and / or the second coupling member forms two partial coupling members connected in series, whereby the coupling member device can absorb large deflection angles. The two partial coupling members are arranged in the first coupling member or the second coupling member and in the coupling member device at the same wheel axle position. For this reason, the coupling device takes up very little installation space in the axial direction. In other words, the partial coupling members of the first coupling member and / or the second coupling member are arranged tangentially and are therefore arranged in a manner that saves installation space. Due to this arrangement of the partial coupling members, at least one intermediate member can be embodied with a predetermined axial extension.

[0007] The first or second wire reinforcement connector can be held in a predetermined radial position by a support device, thereby optimizing the available radial installation space. In particular, the respective wire reinforcement connector can be held in a predetermined radial position by at least one support device, in which radial position the wire reinforcement connector can assume a polygonal shape when viewed in the axial direction. This improves utilization of the available radial installation space of the hollow cylindrical structure or the hollow cylindrical structure.

[0008] The coupling device may further include at least one second coupling member having at least one second wire reinforcement connection device, wherein the second wire reinforcement connection device comprises at least one wire package embedded in at least one elastomer. At least one intermediate member may be provided to connect the first coupling member and the second coupling member to each other. The at least one second coupling member may have at least one support device connected to the second wire reinforcement connection device, wherein the at least one support device can support the second wire reinforcement connection device in a radial direction.

[0009] At least one supporting device can be supported in a cantilevered manner. At least one supporting device can only be in contact with or connected to the wire reinforcement connecting device associated with it. The supporting device is designed not to have to be supported on other components of the coupling device.

[0010] At least one supporting device may have several supporting elements. The supporting elements may extend in the radial direction. The supporting elements may be connected to the line reinforcement connection device. The supporting elements may extend radially inward or outward. The supporting device may have several supporting elements that are staggered with each other in the axial direction, and these supporting elements may occupy a joint device associated with the supporting device between them. In other words, the supporting elements of the supporting device that are connected to the corresponding line reinforcement connection device may extend on both axial sides of the line reinforcement connection device. The supporting elements may be connected to the line reinforcement connection device via connecting elements. These connecting elements may in particular be screws. At least some of the supporting elements may have an opening with an internal thread, into which the connecting elements can be screwed. The connecting elements can therefore be guided through the supporting element and the line reinforcement connection device and screwed onto another radial supporting element.

[0011] At least one support device can be designed in multiple parts. For example, the support device can be constructed in two parts. The two parts of the support device can be mounted on a wire reinforcement connector associated with the support device and connected together. The connection between the parts of the support device can be made via a connecting element, and the wire reinforcement connector is also mounted on the support device using the connecting element.

[0012] At least one supporting device can be designed so that all supporting elements are connected to each other. At least one supporting device can have at least one annular portion, which connects the individual supporting elements to each other. At least one annular portion can extend radially outside around the supporting elements and connect them to each other. At least one annular portion can further extend radially inside along the supporting elements and connect them to each other. At least one annular portion can extend radially outward or radially inward of the line reinforcement connection. The annular portion can have a predetermined axial extension, which is at least greater than or equal to the axial extension of the line reinforcement connection. At least one supporting device can have at least one annular element, from which the supporting elements extend radially inward or outward.

[0013] At least one intermediate member may be supported in a cantilevered manner.At least one intermediate member may be connected exclusively to the wire reinforcement connection device.At least one intermediate member may not be supported on other components of the coupling device.

[0014] The first coupling member can be connected to a first flange having a hub-shaped portion. The hub-shaped portion can be tubular. The hub-shaped portion can extend toward the intermediate member. The hub-shaped portion can extend through one of the wire reinforcement connectors and / or through the support device. The first flange can have a plurality of first flange arms. The first flange arms can extend radially outward from the hub-shaped portion. The first flange can have three first flange arms. The first flange can also have more than three flange arms.

[0015] The second coupling member can be connected to the second flange. The second flange can have a connecting portion designed to receive a plurality of connecting elements. The second flange can have several second flange arms. The second flange can have three flange arms. The second flange can also have more than three flange arms. The second flange can be part of a flange assembly, which can include at least one cover and the second flange. The at least one cover can extend radially outwardly around the support means and the wire reinforcement connector. The wire reinforcement connector and the support means can therefore be arranged radially within the cover.

[0016] The middle piece can be formed into a tubular shape. The middle piece can have multiple arms. The arms of the middle piece can extend in the radial direction. In particular, the arms of the middle piece can extend radially outward. Radial arms can be provided at each axial end of the middle piece. Three arms can be formed at each axial end of the middle piece. The first wire reinforcement connection device can be connected to the first flange arm of the first flange and the arm at the axial end of the middle piece. The second wire reinforcement connection device can be connected to the second flange arm of the second flange and the arm at the corresponding other axial end of the middle piece. The radial support element of the support device of the first coupling piece can be arranged between the first flange arm and the arm of the middle piece in the circumferential direction. The radial support element of the support device of the second coupling piece can be arranged between the second flange arm and the arm of the middle piece in the circumferential direction.

[0017] The wire reinforcement connector may include at least one deflection element that can be connected to the support device. The at least one deflection element may be designed in the form of a bushing. A connecting element connecting the wire reinforcement connector to the support element of the support device may extend through the at least one deflection element. The support device may be coupled to the wire reinforcement connector via the at least one deflection element.

[0018] The first and / or second wire reinforcement couplings may be comprised of several wire reinforcement coupling elements, each comprising at least one elastomer. The wire reinforcement coupling elements may comprise at least two bushings and at least one wire wrap surrounding the two bushings. The at least one wire wrap may be embedded in at least one elastomer. The at least one wire wrap may be retained on the bushings via one or more collar elements. The collar element or collar elements may be pushed onto the bushings in the axial direction of the bushings and retain the at least one wire wrap in its predetermined axial position. The collar element may be integrally formed with the bushings. The collar element may extend radially away from the tubular bushings. The bushings and collar elements may also be at least partially or partially embedded in at least one elastomer. The bushings may be connected to one of the flanges and the intermediate piece, thereby establishing a torque-transmitting connection between the two flanges via the wire reinforcement coupling. For example, three bushings may be associated with a flange associated with the intermediate piece and one of the three bushings. These bushings may then be connected to the corresponding flanges and the intermediate piece. The wire wrap and bushings may be at least partially embedded in at least one elastomer.

[0019] The at least one supporting device may be formed such that it can deflect the wire package of the wire reinforcing connection. The at least one supporting device may preferably deflect the wire package in the area between two corresponding bushings. The number of bushings may correspond to the number of supporting elements.

[0020] The wire reinforcement coupling element can connect the first flange arm of the first flange, the arm of the intermediate piece, and the support element. The wire reinforcement coupling element can connect the flange arm of the second flange, the arm of the intermediate piece, and the support element.

[0021] The supporting device may have at least one plane in common with the first flange arm and / or the second flange arm, which plane extends perpendicular to the center line of the coupling. The same applies to the arms of the intermediate piece. At least the parts of the flange arms of the first flange and the second flange that extend in the radial direction and the supporting element of the supporting device may have a common plane. The axial extension of the supporting device may at least partially overlap with the axial extension of the radial part of the first flange arm and / or the second flange arm. Additionally or alternatively, the axial extension of the supporting device may also overlap with the axial extension of the elastic element. This overlap preferably occurs in the radial direction. The axial extension of the supporting device may correspond to the axial extension of the radial part of the flange arms of the first flange and / or the second flange. The above embodiment can also be applied by analogy to the reception of the intermediate piece.

[0022] The present invention also relates to a wire reinforcement coupling element. The wire reinforcement coupling element includes at least one wire package, at least two bushings, wherein the at least one wire package surrounds the at least two bushings, and at least one deflection element, wherein the at least one wire package rests on the at least one deflection element between the at least two bushings.

[0023] At least one deflection element can be arranged between the two bushings in the circumferential direction. The wire package does not surround the at least one deflection element or only partially surrounds it. The wire package can form two strands in the area between the bushings. The deflection element brings the strands of the wire package closer to each other so that at least one of the strands extends in a twisted or curved manner. The two strands can also have a twist or bend, wherein the strand resting on the deflection element is twisted or curved more strongly. The at least one deflection element can divide the wire package into two branches, each branch having a bushing and extending at an angle to each other. The at least one wire package, the at least two bushings and the at least one deflection element can be at least partially embedded in an elastomer. The at least one deflection element can be arranged in the area between the bushings.

[0024] The wire-reinforced coupling element can have several wire wraps. Each wire wrap can precisely surround two bushings. The wire-reinforced coupling element can have several deflection elements, which are interconnected via at least one connecting element. At least one deflection element can be associated with at least one wire wrap. A bushing surrounded by a wire wrap is only surrounded by this wire wrap, and not by another wire wrap. Each wire wrap can form a unit with two bushings. The wire-reinforced coupling element can have several such units. These units can be at least partially embedded in the elastomer. For example, the wire-reinforced coupling element can have two, three, or more wire wraps.

[0025] The deflection element can be arranged in the area between the bushings. The deflection elements can be connected to each other via connecting elements, which are arranged at the axial ends of the deflection elements. The deflection element can be designed in the form of a bushing. Arranged on the bushing can be a collar element, which can fix the wire package to the bushing. At least some of the bushing, the collar element, the deflection element and the plate-shaped connecting element can be at least partially embedded in the elastomer. For example, the coupling element can have three wire packages. Each wire package can surround two bushings. Each wire package can form a unit with two bushings, which are surrounded by the wire package. The deflection element that can deflect and support the wire package can be arranged between the bushings. The deflection elements can be connected to each other via the plate-shaped connecting element. The deflection element can bring the two wire strands formed by the wire package between the bushings closer to each other, so that one of the wire strands can respectively present a stronger bending and twisting path than the other wire strand. As a result, each wire package can extend in a curved or twisting manner between the bushings.

[0026] Depending on their load (tension or compression), the wire-reinforced coupling elements can be pulled radially inwards or squeezed radially outwards without a supporting device. The supporting device can support the coupling elements in the radial direction. The supporting device can hold the wire-reinforced coupling elements in their predetermined radial position. This can apply in particular to the region of the deflection element, which can be connected to the supporting element. The supporting element can in particular prevent the central region of the deflection element with the wire-reinforced coupling element between the bushings from shifting in the direction of the center line. The supporting element can accordingly ensure that the coupling or the unit formed by the supporting device and the wire-reinforced coupling element can maintain its polygonal structure even during operation of the coupling. This makes it possible to compensate for large deflection angles and optimize the use of the radial installation space, since a polygon with as many edges as possible can optimally fill an installation space in the shape of a circle or hollow cylinder.

[0027] The invention further relates to a bogie for a rail vehicle. The bogie comprises at least one wheelset having a wheel axle, at least one motor and at least one coupling device, wherein the coupling device couples the motor to the wheel axle.

[0028] The motor and / or at least one coupling device can be arranged coaxially with the wheel axle. The wheel axle can extend through the coupling device and / or the motor. The first flange of the coupling device can be non-rotatably connected to the wheel axle. The first flange can be pressed onto the wheel axle with a hub-shaped portion. The second flange can be connected to the motor output shaft via its connecting portion. A predetermined radial distance can be provided between the second flange and the wheel axle. A predetermined radial distance can be provided between the intermediate piece and the wheel axle. The connecting portion can be connected to the motor output shaft, in particular, via a connecting element. The connecting portion can be screwed to the motor output shaft.

[0029] The invention also relates to a rail vehicle having at least one such coupling device or at least one such bogie. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Figure 1 A perspective view of the coupling device 10 is shown. The coupling device 10 comprises a flange 12 and a flange arrangement 14. Arranged between the flange 12 and the flange arrangement 14 are a first coupling element 16, a second coupling element 18 and an intermediate element 20 which connects the first coupling element 16 to the second coupling element 18.

[0042] The (first) flange 12 has a hub-shaped portion 22 and three (first) flange arms 24 extending radially outward from the hub-shaped portion 22. The hub-shaped portion 22 extends in a tubular manner in the direction of the intermediate piece 20. The hub-shaped portion 22 has an opening 26, in the inner circumferential area of which a groove 28 is formed. The first flange 12 can be pressed with its hub-shaped portion 22 onto the wheel axle (not shown) of a wheelset of a rail vehicle.

[0043] The flange device 14 has a cover 30 and a screw portion 34 , by which the flange device 14 can be connected to a motor (not shown).

[0044] The first coupling member 16 has a support device 36 and a plurality of wire reinforcement coupling elements 38. The wire reinforcement coupling elements 38 form a wire reinforcement connection FG1. The support device 36 has a plurality of radial support elements 40 and an annular portion 42. The support elements 40 extend radially inward from the annular portion 42. The support elements 40 are connected to the wire reinforcement coupling elements 38.

[0045] In addition to their connection to the support element 40, the wire reinforcement coupling elements 38 are also connected to the flange arms 24 of the flange 12 and to the intermediate piece 20. The connection of the wire reinforcement coupling elements 38 to the intermediate piece 20 is shown by the connecting plates 44 and the connecting elements 46 associated with these connecting plates 44. The connecting elements 46 may be screws or bolts.

[0046] The second coupling piece 18 comprises a wire reinforcement coupling element 38 and a support arrangement 48 having a radially outwardly extending support element 50. The wire reinforcement coupling element 38 forms a wire reinforcement connection arrangement FG2.

[0047] The support elements 40 and 50 of the support devices 36 and 48 are connected to the line reinforcement coupling element 38 via a connecting element 52. The connecting element 52 extends through the coupling element 38. The support devices 36 and 48 each have support elements that are offset relative to each other in the axial direction and between which the coupling element 38 is arranged, wherein Figure 1 Only support elements 40 and 50 are shown. A connecting element 52 extends between these two support elements 40, 50, which are axially offset relative to each other, and thus passes through the coupling element 38. Some of the support elements 40, 50, which are axially offset relative to each other, may have internal threads. If screws are provided as connecting elements 52, these screws can be screwed into the internal threads of the support elements to connect the support devices 36, 48 to the coupling element 38. The coupling element 38 of the second coupling member 18 is connected to the flange device 14, as shown, via a connecting plate 54 and a connecting element 56. The connecting element 56 extends through the coupling element 38 in the direction of the flange device 14.

[0048] The intermediate piece 20 has an arm 58 extending radially outwards. The intermediate piece 20 is connected to the coupling element 38 of the second coupling piece 18 via the arm 58.

[0049] Figure 2 The coupling device 10 is shown in a top view. The coupling device 10 comprises a flange 12, a flange arrangement 14 and coupling elements 16 and 18 which are arranged in the axial direction between the flange 12 and the flange arrangement 14 and are connected to each other via an intermediate element 20.

[0050] The intermediate piece 20 has arms 58 and 60 extending in the radial direction. The arm 58 is used to connect the intermediate piece 20 to the coupling element ( Figure 2 The arm 60 connects the intermediate member 20 to the line reinforcing coupling element of the first coupling member 16 ( Figure 2 ). Arms 58 and 60 of intermediate member 20 extend radially outwardly from an annular or tubular portion 62.

[0051] The flange assembly 14 has a cover 30, a support assembly 48 and a wire reinforcement coupling element 38 (see FIG. Figure 1 ) extends within the cover 30. In addition to the cover 30, the flange arrangement 14 includes a (second) flange 64, on which the connection portion 34 is formed. The flange 64 has a (second) flange arm 66. The flange 64 is connected to the cover 30 via the flange arm 66, in particular, it is screwed. The connection portion 34 includes several connecting elements 68. The connecting elements 68 can be screws. The connecting elements 68 extend in the axial direction. The connecting elements 68 are used to connect the flange arrangement 14 to the motor output shaft of the motor (not shown).

[0052] Figure 3 A side view of the coupling device 10 is shown, showing the flange device 14 and the coupling element 18. The flange device 14 has a flange 64 and a cover 30. The cover 30 is connected to a flange arm 66 of the flange 64. The flange arm 66 extends radially outward from the connecting portion 34, on which a connecting element 68 can be seen. The flange device 14 or the flange 64 has an opening 70 through which an axle (not shown) can extend. The opening 70 is dimensioned so that the axle (not shown) cannot contact the flange 64 or the connecting portion 34. The flange 64 is connected to the wire reinforcement coupling element 38 or the second coupling element 18 of the wire reinforcement connecting device FG2 via the flange arm 66. The wire reinforcement coupling element 38 is connected to the support element 50 of the support device 48 in the circumferential direction in its central region.

[0053] The support element 50 extends outward in the radial direction. The support device 48 and the coupling element 38 are enclosed in the radial direction by the cover 30. The coupling element 38 is connected to the intermediate piece 20 (see Figure 2). This is indicated by the connecting plate 72 and the connecting element 74 associated with the connecting plate 72. The cover 30 is connected to the radially outer end portion of the coupling arm 66. In particular, the flange arm 66 can be screwed to the cover 30.

[0054] Figure 4 A perspective view of the coupling device 10 is shown, in which the support devices 36 and 48 and the cover 30 of the flange device 14 have been removed. The flange 12 has flange arms 24 extending from a hub-shaped portion 22. The hub-shaped portion 22 extends through the coupling element 38 in the direction of the intermediate piece 20. The flange arms 24 are connected to the line-reinforcing coupling element 38. In their central region, the line-reinforcing coupling elements 38 have deflection elements (not shown), through which connecting elements 52 extend. The coupling element 38 is connected to the arm 60 of the intermediate piece 20 via a connecting element 46. The arm 58 of the intermediate piece 20 is likewise connected to the line-reinforcing coupling element 38 of the coupling 18 via a connecting element 74. The coupling element 38 of the coupling 18 likewise has a deflection element (not shown) in its central region. Extending through these deflection elements is the connecting element 52, which connects the line-reinforcing coupling element 38 to the support device 48 (see Figure 1 ). The wire reinforcement coupling element 38 is connected to the flange arm 66 of the flange 64 of the flange device 14 via the connecting element 56. The connecting elements 46, 52, 56 and 74 can be screws. In particular, the connecting elements 46, 52, 56 and 74 can be screws with a hexagonal head.

[0055] The flange arm 66 has a recess 76, and the cover 30 (see Figure 1 ) can be supported on the recess 76. In the recess 76 a connecting element 78 can be seen, via which the cover 30 can be attached to the flange arm 66.

[0056] Figure 5 Another top view of the coupling device 10 is shown. Figure 5 , the flange 12, the support means 36 of the coupling 16, the intermediate piece 20, the cover 30, the coupling 18, and the flange means 14 are shown. The intermediate piece 20 has a tubular portion 62 and arms 58, 60. The arms 58 and 60 extend radially outward from the tubular portion 62. The intermediate piece 20 is connected to the first coupling 16 via the arm 60 and to the second coupling 18 via the arm 58.

[0057] Figure 6 Shown along Figure 5 Sectional view along section line VI-VI. Figure 6 Thus, a cross-sectional view of the coupling 16 and the support device 36 is shown. The hub-shaped portion of the flange 12 and the annular element 42 of the support device 36 are shown in FIG. Figure 6The wire reinforcing coupling element 38 is arranged in the radial direction between the hub portion 22 of the flange 12 and the annular element 42 of the support device 36. Figure 4 In the view of FIG, extending radially outwardly around the support device 36 is a cover 30, which is not shown in section. In the support device 36 shown in section, several openings can be identified through which screws extend to connect the two parts of the support device 36.

[0058] Each wire reinforcement coupling element 38 includes three wire wraps 80a, 80b, and 80c. Each wire wrap 80a, 80b, and 80c surrounds two bushings 82. A deflection element 84 is provided in the area between the bushings 82, upon which the wire wraps 80a, 80b, and 80c can be supported. The deflection element 84 forces the wire wraps 80a, 80b, and 80c to bend or twist. Thus, the coupling element 38 as a whole has a twisted or angled form. The connecting element 52 extends through the deflection element 84 to connect the coupling element 38 to the support device 36 or to the support element 38.

[0059] Figure 7 A perspective view of a wire reinforcement coupling element 38 according to a first exemplary embodiment is shown. The wire reinforcement coupling element 38 has six bushings 82 and a deflection element 84. The deflection elements 84 are arranged in the region between the bushings 82. The deflection elements 84 are connected to one another via connecting elements 90, which are arranged at the axial ends of the deflection elements 84. The deflection elements 84 are formed in the form of bushings. A collar element 92 can be identified on the bushings 82, which connects the deflection elements 84 to the bushings. Figure 7 The wire package, not shown, is held on the bushing 82 .

[0060] Figure 8 Shown according to Figure 7 86. The bushing 82, the collar element 92, the deflection element 84 and the plate-like connecting element 90 are partially embedded in the elastomer 86. Recognizable in the elastomer 86 are recesses or openings 94 formed between the strands of the wire package 80 in the elastomer 86 ( Figure 9 not shown).

[0061] Figure 9 Shown along Figure 8 Sectional view of section line IX-IX in. Figure 9, a wire package 80 is shown in cross-section at four points along section line IX-IX. The wire package 80 surrounds a bushing 82. A collar member 92 is provided on the bushing 82, extending radially from the tubular portion of the bushing 82. The collar member 92 may be integrally formed with the bushing 82. The bushing 92 holds the wire package 80 at a predetermined axial position on the bushing 82. The bushing 82, having the collar member 92 formed thereon, has a spool shape.

[0062] In the area between the two bushings 82, the deflection element 84 is shown. The deflection element 84 is not surrounded, or is barely surrounded, by the wire package 80. The wire package 80 extends along the deflection element 84 and rests in one area with one of its strands on the outer circumference of the deflection element 84. In addition, a recess or opening 94 is visible in the elastomer 86.

[0063] Figure 10 FIG. 1 shows a perspective view of the base of the wire reinforcement coupling element 38. The three wire packages 80a, 80b, 80c of the wire reinforcement coupling element 38 are Figure 10 identifiable in . Each of the wire bundles 80a, 80b, 80c surrounds two bushings. Each of the wire bundles 80a, 80b, 80c forms a unit having two bushings 82, which are surrounded by the wire bundles 80a, 80b, 80c. Disposed between the bushings 82 is a deflection element 84, which can deflect and support the wire bundles 80a, 80b, 80c. The deflection elements 84 are connected to each other via a plate-like connecting element 90. The deflection element 84 brings the two strands 88a and 88b formed by the wire bundle between the bushings 82 closer to each other, so that the strand 88b exhibits a stronger torsional progression than the strand 88a. The strand 88a is less torsionally bent than the torsion in the strand 88b. Therefore, each of the wire bundles 80a, 80b, 80c extends in a torsional manner between the bushings 82.

[0064] Figure 11 A side view of the wire reinforcement coupling element 38 is shown. Figure 11 In the view of FIG. 8 , the elastomer 86 , the connecting plate 90 partially embedded in the elastomer 86 and the end of the bushing 82 are recognizable.

[0065] Figure 12 Shown along Figure 11Sectional view along section line XII-XII in . The wire packages 80a, 80b, 80c each surround exactly two bushings. In the area between the bushings, the wire packages 80a, 80b, 80c form two strands 88a and 88b. The deflection element 84 deflects these strands 88a and 88b in the area between the bushings. By this deflection in the area of the deflection element 84, the strands 88a and 88b are brought closer to each other. The strand 88b rests on the area of the outer circumferential surface of the deflection element 84. The strand 88a rests on the strand 88b in this area, i.e. in the area of the deflection element 84. The wire packages 80a, 80b, 80c thus present an angled progression. The deflection element 84 divides the wire packages 80a, 80b, 80c into two branches, each of which has a bushing 82 and extends at an angle to each other. The bushing 82 , the coils 80 a , 80 b , 80 c and the deflection element 84 are embedded in an elastomer 86 .

[0066] Figures 13 to 18 A wire reinforcement coupling element 38 according to a second exemplary embodiment is shown. Figures 7 to 12 A significant difference from the first exemplary embodiment is the fact that two deflection elements 84 are associated with each wire package 80a, 80b, 80c. Each wire strand 88a, 88b of a wire package 80a, 80b, 80c is deflected by its own deflection element 84 in the area between the bushings 82. Consequently, the wire strands 88a, 88b of a wire package 80a, 80b, 80c are no longer adjacent to one another in the area of the deflection elements 84, but are instead spaced apart from one another by the deflection elements 84. Each of the wire strands 88a, 88b has a torsion set by the deflection element 84. The deflection elements 84 are connected to one another via a plate-like connecting element 90. Compared to the above exemplary embodiment, the diameter of the deflection elements 84 is reduced.

[0067] Figure 19 The first coupling member 18 is shown (see Figure 1 ) of the front view of the support device 36, wherein according to Figures 7 to 12 The wire reinforcing coupling element 38 of the first exemplary embodiment shown is mounted on the support device 36. The support device 36 has an annular portion 42 and a support element 40 extending radially inwardly from the annular portion 42. The support element 40 is connected to the deflection element 84 (see FIG. 1 ) via screws 52. Figures 7 to 12 With its support element 40, the support device 36 supports the central region of the wire reinforcement coupling element 38, in which region the deflection element 84 is arranged. The wire reinforcement coupling element 38 can be screwed onto the first flange 12 via screws 56. For this purpose, the screws 56 are guided through the bushings 82 (see Figures 7 to 12 ). The screw 46 can be guided through the bushing 82 in the same manner to connect the wire reinforcement coupling element 38 to the intermediate piece 20 (see Figure 1 ).

[0068] Figure 20 The support device 48 of the second coupling element 18 is shown in a front view. The support device 48 has an annular portion 96 and a support element 50 extending radially outward from the annular portion 96. The annular portion 96 extends radially within the wire reinforcement coupling element 38. The wire reinforcement coupling element 38 is connected to the support element 50 via a screw 52. For this purpose, the screw 52 is guided through the deflection element 84 (see FIG. Figures 7 to 12 ). The wire reinforcement coupling element 38 can be screwed to the second flange 64 via screws 56 (see Figure 1 ). Screw 74 connects the wire reinforcement coupling element 38 to the intermediate member 20 (see Figure 1 The radially outwardly extending support element 50 holds the deflection element 84 and thus the central region of the line reinforcement coupling element 38 in a predetermined radial position. The unit formed by the support device 48 and the coupling element 38 thus maintains its polygonal structure.

[0069] Depending on the load (tension or compression) on which they are loaded, the wire-reinforced coupling elements 38 can be pulled radially inward or squeezed radially outward without the support devices 36, 48. The support devices 36, 48 support the coupling elements 38 in the radial direction. The support devices 36, 48 maintain the wire-reinforced coupling elements 38 in their predetermined radial position. This applies in particular to the region of the deflection elements 84 connected to the support elements 40, 50. In particular, the support elements 40, 50 prevent the central region between the bushings 82 from shifting in the direction of the centerline M by means of the deflection elements 84 of the wire-reinforced coupling elements 38. The support elements 40, 50 accordingly ensure that the coupling or unit formed by the support devices 36, 48 and the wire-reinforced coupling elements 38 maintains its polygonal structure even during operation of the coupling. This allows large deflection angles to be compensated and the radial installation space to be optimally utilized, since a polygon with as many edges as possible can optimally fill an installation space in the form of a circle or hollow cylinder.

[0070] Figure 21 A top view of a bogie 1000 is shown. The bogie 1000 has two wheel sets 1002 and 1004. Each wheel set 1002, 1004 has two wheels 1006, 1008 connected to each other by an axle 1010. A coupling device 10 is arranged coaxially with the axle 1010. The coupling device 10 connects the wheel sets 1002, 1004 to a motor 1012. The coupling 10 can be coupled to the axle 1010 and a motor output shaft (not shown) of the motor 1012. The coupling 10 and the motor 1012 can be arranged coaxially with the axle 1010. The first flange 12 (see Figure 1) can be non-rotatably connected to axle 1010. Flange 12 can, for example, be pressed onto axle 1010. Second flange 64 can be connected to a motor output shaft (not shown) of motor 1012. For this purpose, connecting element 68 of flange 64 can be connected to the motor output shaft. Axle 1010 extends through coupling device 10 and also through motor 1012. Motor 1012 can be a traction motor that can drive wheelsets 1002, 1004 without a transmission.

[0071] Especially in Figure 21 As can be seen in the figure, the coupling 10 only requires a very small installation space in the axial direction, but can still produce a large deflection angle so as to compensate for the relative movement between the motor 1012 and the wheel sets 1002 and 1004.

[0072] The support device described above supports the wire reinforcement connector in the radial direction. It can maintain the wire reinforcement connector in its predetermined radial position. Due to reaction forces generated during operation of the coupling or the wire reinforcement connector, the support device prevents the wire reinforcement connector from moving radially inward or radially outward. Thus, the supporting elements of the support device ensure that the coupling retains its polygonal structure even during operation. This allows large deflection angles to be compensated and optimal use of the radial installation space to be made, as a polygon with as many edges as possible can optimally fill the installation space in the form of a circle or hollow cylinder.
