(20) FIG. 19 shows a sectional view of a fiber-reinforced elastic joint body according to the ninth embodiment of the invention.

(21) FIG. 1 shows a top view of an elastic joint body, denoted overall by reference numeral 10.

(22) The elastic joint body 10 has an elastic body 12 and bushings 14. The bushings 14 have a flange-like head 16 at one of their ends. The respective other end of the bushings is designed without such a head. At the axial surface of the elastic joint body shown in FIG. 1, the bushings 14 are situated with their end having the head 16 in alternation with their respective other end (without a head) in the circumferential direction of the elastic joint body 10. Collar elements 18 are discernible at the ends without a head. The collar elements 18 and the bushings 14 are at least partially embedded in the elastic body 12.

(23) The center axis of the elastic joint body 10 is denoted by reference character M.sub.G, and the center axis of the bushings is denoted by reference character M.sub.B. When reference is made below to an axial direction or axial position, these statements always refer to the axial extension of one or both axes M.sub.G and M.sub.B.

(24) The center axes M.sub.B of all bushings 14 lie on an imaginary circle K about the center axis M.sub.G of the elastic joint body 10. In other words, the center axes M.sub.B of the bushings 14 all lie on a radius about the center axis M.sub.G of the elastic joint body 10. The diameter of this imaginary circle K corresponds to the connection diameter LK.

(25) FIG. 2 shows a sectional view along the section line II-II in FIG. 1.

(26) In addition to the collar element 18 already shown in FIG. 1, collar elements 20 and 22 are also situated on the bushings 14. The collar elements 18, 20, and 22 form a support device for axially supporting and guiding thread packets 24, 26, 28, respectively. The collar elements 18 and 20 are situated at the axial end sections of the bushings 14. The collar element 22 is situated between the collar elements 18 and 20. The collar elements 18 and 20 thus form axially outer collar elements. The collar element 22 represents an axially inner collar element.

(27) The axially outer collar elements 18 and 20 are designed as L-shaped collars. The collar elements 18 and 20 accordingly have an axial section 18a and 20a, respectively, that rests against the bushings 14. The sections 18a and 20a have a tubular design. The axial end-face sides of these tubular sections 18a and 20a face in the direction of the axial ends of the bushings 14. The head 16 of the bushing 14 rests against the end-face side of the section 18a of the collar element 18. The collar elements 18 and 20 likewise have radial sections 18b and 20b in addition to the axial sections 18a and 20a. The radial sections 18b and 20b extend outwardly in the radial direction, starting from the axial sections 18a and 20a.

(28) The axially inner collar element 22 has a U-shaped cross section. The collar element 22 has two radial sections 22a and 22b. An axial section 22c, which connects the two radial sections 22a and 22b to one another, extends between the two radial sections 22a and 22b. The collar element 22 accommodates the thread packet 28. The distance between the radial sections 22a and 22b corresponds to the axial extension of the thread packet 28. The thread packet 28 is situated in a pulling segment of the elastic joint body 10, and is thus subjected to tension in the pulling mode of the elastic joint body 10.

(29) The thread packets 24 and 26 are situated in a pushing segment that is subjected to tension in the pushing mode of the elastic joint body 10. Since lower loads occur in the pushing mode of the elastic joint body 10, the thread packets 24 and 26 in total have a smaller cross section than the thread packet 28. The thread packets 24 and 26 are guided between the radial sections 22a and 22b of the collar element 22 and the radial sections 18b and 20b of the collar elements 18 and 20. The axial distance between the radial sections 18b, 20b, 22a, and 22b thus determines the cross section of the thread packets 24 and 28.

(30) In contrast to the thread packet 28, the thread packets 24 and 26 rest, at least in sections, directly against the outer circumferential surface of the bushing 14. The thread packet 28 rests only against the collar element 22, and therefore does not come into contact with the bushing 14.

(31) FIG. 3 shows an enlarged detail of the sectional view according to FIG. 2. Various dimensions of the components of the elastic joint body 10 are provided in the view according to FIG. 3.

(32) The provided dimensions refer to the individual elements of the elastic joint body 10, as follows: a1: thickness (extension in the direction of the center axis M.sub.B of the bushing 14) of the radial section 20b of the collar element 20; a2: thickness (extension in the direction of the center axis M.sub.B of the bushing 14) of the radial section 22b of the collar element 22; a3: thickness (extension in the direction of the center axis M.sub.B of the bushing 14) of the radial section 22a of the collar element 22; a4: thickness (extension in the direction of the center axis M.sub.B of the bushing 14) of the radial section 18b of the collar element 18; b1: thickness (extension in the radial direction) of the axial section 20a of the collar element 20; b2: thickness (extension in the radial direction) of the axial section 22c of the collar element 22; b3: thickness (extension in the radial direction) of the axial section 18a of the collar element 18; h1: radial extension of the radial section 20b of the collar element 20, starting from the axial section 20a; h2: radial extension of the radial sections 22a and 22b of the collar element 22, starting from the axial section 22c; h3: radial extension of the radial section 18b of the collar element 18, starting from the axial section 18a; I1: axial extension of the thread packet 26; I2: axial extension of the thread packet 28; I3: axial extension of the thread packet 24; d1: outer diameter of the bushing 14; d2: outer diameter of the radial sections 22a and 22b of the collar element 22; d3: inner diameter of the bushing 14; d4: outer diameter of the radial sections 18b and 20b of the collar elements 18 and 20; LK: diameter of the circle on which the center axes M.sub.B of the bushings 14 lie, the diameter of this circle indicating the connection diameter of the elastic joint body 10; and R1, R2, R3, R4 predetermined radii of the transitions between the axial sections 18a, 20a, and 22c into the radial sections 18b, 20b, 22a, and 22b of the collar elements 18, 20, 22.

(33) The ratios of the joint body described above may be indicated, based on these dimensions.

(34) The ratio u.sub.1 may thus be determined from:

(35) $u_1=\frac{l_1+l_2+l_3}{\mathrm{LK}}$

(36) The sum of the axial extension I.sub.1, I.sub.2, I.sub.3 may be 22 mm, for example. The connection diameter LK may be 110 mm, for example. This results in a value of 0.2 for the ratio u.sub.1.

(37) The ratio u.sub.2 may be determined from:

(38) $u_2=\frac{l_1+l_2+l_3}{d_2}$

(39) The outer diameter d.sub.2 of the radial sections 22a and 22b of the collar element 22 is preferably used for the ratio u.sub.2. The outer diameter d.sub.2 of the radial sections 22a and 22b may be 30 mm, for example. A value of 0.7 may result for the ratio u.sub.2.

(40) The ratio u.sub.3 results from:

(41) $u_3=\frac{l_1+l_2+l_3+a_1+a_2+a_3+a_4}{d_2}$

(42) The outer diameter d.sub.2 of the radial sections 22a and 22b of the axially inner collar element 22 is also used for the ratio u.sub.3. Once again, the value of 22 mm by way of example is used for the axial extension of the thread packets 24, 26, 28. The thickness of the radial sections 18b, 20b, 22a, and 22b may be assumed to be 1 mm. The outer diameter of d.sub.2 is once again assumed to be 30 mm. Based on these values, a value of 0.87 then results for the ratio u.sub.3.

(43) The ratio u.sub.4 may be determined from:

(44) $u_4=\frac{l_1+l_2+l_3+a_1+a_2+a_3+a_4}{\mathrm{LK}}$

(45) Based on the values given above, this results in a value of 0.24 for the ratio u.sub.4.

(46) The ratio u.sub.5 may be determined from:

(47) 0$u_5=\frac{l_2}{d_2}$

(48) A value of 12 mm may be assumed for the axial extension 12 of the thread packet 28. A value of 0.4 may result for the ratio u.sub.5, with an outer diameter d.sub.2 of the radial sections 22a and 22b of the collar element 22 of 30 mm.

(49) The ratio u.sub.6 may be determined from:

(50) $u_6=\frac{l_1}{l_2}$

(51) In other words, the elastic joint body 10 according to the invention may have a predetermined ratio of the axial extension 12 of the thread packet 28 in the pulling segment to the axial extension I.sub.1 of a thread packet 24 or 26 in the pushing segment. A value of 5 mm may be assumed for the axial extension I.sub.1 of a thread packet 24 or 26 in the pushing segment, and a value of 12 mm may be assumed for the axial extension 12 of the thread packet 28 in the pulling segment. This results in a value of 0.42 for the ratio u.sub.6.

(52) The ratio u.sub.7 results from the following equation:

(53) $u_7=\frac{h_1+b_1}{l_1}$
b1 indicates the thickness (extension in the radial direction) of the axial section 20a of the collar element 20. h1 indicates the radial extension of the radial section 20b of the collar element 20, starting from the axial section 20a. b1 may be assumed to be 1 mm, and h1 may be assumed to be 5 mm. The axial extension I.sub.1 of the thread packet 26 is once again assumed to be 5 mm. This results in a value of 1.2 for the ratio u.sub.7.

(54) In addition, the outer diameter d2 of the radial sections 22a and 22b may be larger than the outer diameter d4 of one of the radial sections 18b and 20b of one of the collar elements 18 and 20. Accordingly, d.sub.2>d.sub.4 may apply (as shown in FIG. 5).

(55) The ratios and equations discussed above may be adapted to the embodiments described below, whereby values that lie within the ranges stated above also result for the ratios u.sub.1 through u.sub.7 for the embodiments described below.

(56) FIG. 4 shows a top view of an elastic joint body 110 according to a second embodiment of the invention.

(57) The joint body 110 has an elastic body 12 and bushings 14. Collar elements 18 are provided at the bushings 14. The bushings 14 have a head 16 at their ends.

(58) FIG. 5 shows a sectional view along the section line V-V in FIG. 4.

(59) The elastic joint body 110 has two collar elements 18 and 20. The collar elements 18 and 20 have radial sections 18a, 18b, 20a, 20b and axial sections 18c and 20c, 18d and 20d. The axial sections 18c and 20c extend via section 18d and 20d beyond the axially outer radial section 18b and 20b in the axial direction. The sections 18d and 20d face in the direction of the axial ends of the bushings 14. The sections 18d and 20d thus extend between the end of the bushings and the axially outer radial section 18b and 20b. The radial sections 18a, 18b and 20a, 20b together with the axial sections 18c and 20c form a U-shaped area of the collar elements 18 and 20 in which the thread packets 18 and 20 are accommodated. The thread packet 28 is guided in the pulling segment, between the axially inner radial sections 18a and 20a. Thus, no additional axially inner collar element is provided in this embodiment.

(60) FIG. 6 shows a top view of an elastic joint body 210 according to a third embodiment of the invention.

(61) The top view of the elastic joint body 210 corresponds to the top view of the elastic joint body 110, which has already been described in detail above.

(62) The essential difference between the embodiment shown in FIGS. 4 and 5 and the embodiment according to FIGS. 6 and 7 lies in the arrangement of an additional axially inner collar element 22. The collar element 22 has a U-shaped cross section and accommodates the thread packet 28. The axially outer collar elements 18 and 20 correspond to the collar elements 18 and 20 described with reference to FIGS. 4 and 5. The radial sections 22a and 22b of the axially inner collar element 22 rest against the radial sections 18a and 20a. The thread packet 28 is thus separated from the thread packet 24 by the radial sections 18a and 22a of the collar elements 18, 20, and is separated from the thread packet 26 by the radial sections 20a and 22b of the collar elements 18, 20.

(63) In the elastic joint body 110, the thread packets 24, 26, 28 may be directly wound into their associated U-shaped collar elements 18, 20, and 22. The collar elements 18, 20, 22 and the thread packets 24, 26, 28 wound into the collar elements 18, 20, 22 may subsequently be fitted or pressed onto the bushings 14.

(64) FIG. 8 shows a top view of an elastic joint body 310 according to a fourth embodiment of the invention.

(65) The elastic joint body 310 has an elastic casing 12 or an elastic body 12, and bushings 14. Collar elements are not discernible at the surface of the elastic joint body 310.

(66) FIG. 9 shows a sectional view along the section line IX-IX in FIG. 8.

(67) The elastic joint body 310 has two collar elements 18 and 20 having a U-shaped cross section. The collar elements 18 and 20 accommodate a thread packet 24, 26, respectively. The collar elements 18 and 20 guide the thread packet 28 in the pulling segment, between their oppositely situated radial sections 18a and 20a. The thread packet 28 thus extends axially within the radial sections 18a and 20a. Thus, no separate axially inner collar element for guiding the thread packet 28 is provided.

(68) The fifth embodiment shown in FIGS. 10 and 11 largely corresponds to the embodiments described with reference to FIGS. 8 and 9. FIG. 10 shows a top view of the elastic joint body 410, and FIG. 11 shows a sectional view along the section line XI-XI in FIG. 10.

(69) The only difference from the embodiment according to FIGS. 8 and 9 is the axially inner collar element 22. The axially inner collar element 22 has a U-shaped cross section, and has already been described in detail above. According to this embodiment, three collar elements 18, 20, 22 having two respective radial sections 18a, 18b, 20a, 20b, 22a, 22b are thus provided. The radial sections 18a and 22a of the collar elements 18 and 22 rest against one another. The same applies for the radial sections 20a and 22b, which likewise rest against one another. The axial sections 18c, 20c, and 22c of the collar elements 18, 20, 22 rest against the outer circumferential surface of the bushing 14.

(70) FIG. 12 shows a top view of an elastic joint body 510 according to a sixth embodiment of the invention.

(71) The elastic joint body 510 has an elastic body 12 in which bushings 14 are accommodated.

(72) FIG. 13 shows a sectional view along the section line XIII-XIII in FIG. 12.

(73) The elastic joint body 510 according to the sixth embodiment has five thread packets 24, 26, 28, 30, 32. The thread packets 24, 26, 28, 30, 32 have the same cross section; i.e., their extensions in the radial direction and in the axial direction are equal. The thread packets 24, 26, 28, 30, 32 are accommodated in five U-shaped collar elements 18, 20, 22, 34, 36. The individual radial and axial sections of the collar elements 20, 22, 34 and 36 are not provided with reference numerals in FIG. 13 for reasons of clarity. Since the collar elements 18, 20, 22, 34, 36 all have essentially the same design, only the collar element 18 is described by way of example. The collar element 18 has two radial sections 18a and 18b, which are connected to one another via an axial section 18c. The thread packet 24 is accommodated between the radial sections 18a and 18b. The cross section of the thread packet 24 is adapted to the distance between the radial sections 18a and 18b of the collar elements 18, so that the thread packet 24 may be completely accommodated in the collar element 18.

(74) The thread packets 24, 28, 32 are subjected to tension in the pulling mode of the elastic joint body 610. The thread packets 26, 30, situated between the thread packets 24, 28, and 30, are subjected to tension in the pushing mode of the elastic joint body.

(75) The thread packets 24, 26, 28, 30, 32 all have the same cross section. The thread packets 24, 26, 28, 30, 32 are separated from one another in the axial direction by two radial sections of the collar elements 18, 20, 22, 34, 36 in each case.

(76) FIG. 14 shows a top view of an elastic joint body 610 according to a seventh embodiment of the invention.

(77) The elastic joint body 610 has an elastic body 12, and bushings 14 that are accommodated in the elastic body 12, offset relative to one another in the circumferential direction.

(78) FIG. 15 shows a sectional view along the section line XV-XV in FIG. 14.

(79) The elastic joint body 610 has three collar elements 18, 22, 36 in which the thread packets 24, 28, and 32, respectively, are accommodated. The collar elements 18, 22, 36 have identical cross sections. The collar elements 18, 22, 36 have a U-shaped cross section. Thus, the collar elements 18, 22, 36 each have two radial sections, and an axial section that connects the two radial sections. This is indicated by sections 18a, 18b, and 18c of the collar element 18, which are provided with reference numerals by way of example. The collar element 18 has two radial sections 18a and 18b that are connected via an axial section 18c. The collar elements 22 and 36 have the same design and construction as the collar element 18. The collar elements 18, 22, 36 rest with their axial section against the outer circumferential surface of the bushings 14.

(80) The thread packets 26 and 30 are supported and axially guided by oppositely situated radial sections of the collar elements 18, 22, and 36. Thus, the thread packets 26 and 30 are not accommodated in a separate collar element.

(81) The thread packets 26 and 30 thus rest, in sections, directly against the outer circumferential surface of the bushings 14.

(82) FIG. 16 shows a top view of an elastic joint body 710 according to an eighth embodiment of the invention.

(83) The elastic joint body 710 has bushings 14 that are accommodated in an elastic body 12.

(84) FIG. 17 shows a sectional view along the section line XVII-XVII in FIG. 16.

(85) The elastic joint body 710 has four U-shaped collar elements 18, 20, 34, and 36. The collar elements 18, 20, 34, and 36 accommodate a thread packet 24, 26, 30, and 32, respectively, in their U shape. Another thread packet 28 having a larger cross section than the thread packets 24, 26, 30, and 32 is provided between the collar elements 20 and 34. The thread packet 28 rests, at least in sections, directly against the outer circumferential surface of the bushings 14. The thread packet 28 is guided by oppositely situated radial sections of the collar elements 20 and 34. The thread packet 28 and the thread packets 24 and 32 are situated in a pulling segment of the elastic joint body 710. The thread packets 26 and 30 are situated in a pushing segment of the elastic joint body 710.

(86) The collar elements 18, 20, 34, and 36 have designs that are identical to the U-shaped collar elements described above. The collar elements 18, 20, 34, and 36 have an identical design; i.e., the radial sections and axial sections of each of the collar elements 18, 20, 34, and 36 are identical in their extensions.

(87) FIG. 18 shows a top view of a fiber-reinforced elastic joint body 810 according to a ninth embodiment of the invention.

(88) The fiber-reinforced elastic joint body 810 is less circular than the joint body described above. The basic shape of the fiber-reinforced elastic joint body 810 corresponds to a polygon.

(89) The fiber-reinforced elastic joint body 810 has an elastic body 12, and bushings 14 that are accommodated in the elastic body 12. The bushings 14 have a tubular design.

(90) FIG. 19 shows a sectional view along the section line XIX-XIX in FIG. 18.

(91) The fiber-reinforced elastic joint body 810 has two U-shaped collar elements 18 and 20. The elastic joint body 810 also has two thread packets 24 and 26. The thread packet 24 is accommodated in the collar element 18. The thread packet 26 is accommodated in the collar element 20. The thread packet 24 is situated in a pulling segment, and therefore has a larger cross section than the thread packet 26, situated in a pushing segment of the fiber-reinforced elastic joint body 810.

(92) The collar elements 18 and 20 have two radial sections 18a, 18b and 20a, 20b, respectively. The radial sections 18a, 18b and 20a, 20b are connected to one another via an axial section 18c and 20c, respectively. The axial section 18c of the collar element 18 is longer in the axial direction than is the axial section 20c of the collar element 20. Since the thread packet 24 has a larger cross section, the collar element 18 associated with this thread packet 24 must also be larger than the collar element 20. However, the extensions of the radial sections 18a, 18b and 20a, 20b of the two collar elements 18 and 20 are identical, so that the only difference lies in the axial extension of the axial sections 18c and 20c. The collar elements 18 and 20 in their extensions in the radial and axial direction are coordinated with the predetermined cross section of the thread packets 24 and 26.
