[0089] The rod 15 includes three successive—a first, a second and a third—rod sections 16, 17, 18. With the two-part hinge device 11 in the assembled state, the first rod section 16 is supported in the first housing part 20 by a clamping element 50. The third rod section 18 bears a bushing 25 and therewith the second housing part 30, wherein a portion of the third rod section 18 is arranged in the bushing 25. An axial bearing 45 is arranged between the second housing part 30 and the bushing 25. In the region of the second rod section 17, the rod 15 is adjustable relative to the first housing part 20 in two directions X, Y which are at an angle β to each other, wherein the two directions X, Y at an angle β to each other are arranged transversely to the axial direction 60 of the rod 15. The rod 15 is also adjustable in direction X, and in direction Y independently thereof. The two-part hinge device 11 comprises positioning elements for adjusting the rod 15. The positioning elements shown are spindles 22 and 32, each of which has a thread and may be screwed into two threaded holes 19, 19a in order to adjust the rod 15. For this purpose, the inner sides of the threaded holes 19, 19a are furnished with corresponding threads. The two threaded holes 19, 19a extend in two directions X,Y at angle β to each other in the second rod section 17. The rod 15 is clamped in the radial direction with respect to the first housing part 20 at the first rod section 16.
[0090] The first housing part 20 has a first adjustment opening 23 and a second adjustment opening 24, which are arranged in two directions X, Y that are offset with respect to one another by angle β. In the assembled state, the rod 15 of the two-part hinge device 11 can be adjusted by means of the spindles 22 and 32 and with a tool, wherein the tool is inserted in the respective adjustment opening 23, 24 to turn or actuate the spindles 22, 32 (not shown). Alternatively, other positioning elements are suitable, for example screws, pins, bolts and the like.
[0091]
[0092] The first rod section 16 of the rod 15 includes a substantially cylindrical section 16a and a ball head 52 which precisely fits the clamping element 50, wherein the clamping element 50 comprises a hollow spherical bearing 53. A pull-out guard 35 is also provided, which fixes the rod 15 in the first housing part 20. The hollow spherical bearing 53 is introduced into a bearing opening 26 of the first housing part 20 and fixed in place there. In this way, the rod 15 is clamped at a single point in the hollow spherical bearing 53 and thus also in the first housing part 20. The rod 15 is secured against undesirable axial rotation about the axial direction 60 with an antirotation device 51, wherein the antirotation device 51 is arranged between the first housing part 20 and the hollow spherical bearing 53. For this purpose, the first rod section 16 of the rod 15 has a polygonal section 50a. The polygonal section 50a on the first rod section 16 holds the rod 15 non-rotatably about the axial direction 60 in the first housing part 20 by cooperating with the antirotation device 51. The third rod section 18 of the rod 15 is embodied as a ball-head bolt 18a on which the bushing 25 is supported.
[0093] Alternatively, the second rod section of the suspension rod 15 has a spherical section or a cylindrical section, wherein the respective section comprises at least one positioning element, as described herein (not shown). Alternatively, the second rod section of the suspension rod 15 includes a section with a cross-section that is larger than the first rod section (not shown).

[0101] The rod 315 has three successive—a first, a second and a third—rod sections 316, 317, 318. With the two-part hinge device 311 in the assembled state, the first rod section 316 is supported in the first housing part 20 by a clamping element 350. The first rod section 316 of the rod 315 has a ball head 352 which fits precisely in the clamping element 350 and is fixed in place by the hollow spherical bearing 353. Adjustment of the rod 315 is carried out at the second rod section 317, wherein the polygonal section 317a has surfaces in which the threaded holes 319, 319a are arranged, as described previously with reference to
[0102] An antirotation device 351 is arranged inside the ball head 352 to hold the rod 315 non-rotatably about the axial direction 360 in the first housing part 20. In this case, the antirotation device 351 is designed as a first bolt 351a, at least a portion of which extends through the ball head 352 and partially protrudes from the ball head 352. The protruding section of the first bolt 351a is in operative connection with the first housing part 20, as it extends in an elongated hole or groove in the first housing part 20, and the rod 315 is held in place non-rotatably. The first bolt 351a also functions as a pull-out guard.
[0103] The third rod section 318 of the rod 315 is also embodied as a ball-head bolt 318a on which the bushing 325 is supported. The ball-head bolt 318a includes an antirotation device 351, which is in the form of a second bolt 318b, at least a portion of which extends through the ball-head bolt 318a and a portion of which protrudes from the ball-head bolt 318a. The protruding section of the second bolt 318b is in operative connection with the bushing 325, as it extends in an elongated hole or a groove, so that the rod 315 is held in place in non-rotatable manner.

[0114] When the two-part hinge device 511 is in the assembled state, the first rod section 516 is supported in the first housing part 520 by a clamping element 550. The clamping element 550 comprises a cover 552, on which the first rod section 516 stands. The third rod section 518 supports the second housing part 530. In the region of the second rod section 517, the rod 515 is adjustable relative to the first housing part 520 in two directions X, Y at an angle β to each other, wherein the two directions X, Y at an angle β to each other are aligned transversely to the axial direction 560 of the rod 515. The rod 515 is adjustable in direction X and also in direction Y independently thereof. The two-part hinge device 511 comprises positioning elements for adjustment of the rod 515. The positioning elements shown are four spindles 522, 527 and 532, 535, each of which is furnished with a thread, and which may be screwed into and out of threaded holes 519, 519a, 519b, 519c for adjusting the rod 515. In this context, one spindle 527, 535 is arranged in each of the first rod section 516 and the third rod section 518, which have two directions X, Y at an angle β to each other, and wherein two spindles 522 and 532 are arranged in the second rod section 517, wherein the first spindle 532 is aligned in the second rod section 517 parallel to the spindle 535 of the first rod section 516 and the second spindle 522 is aligned in the second rod section 517 parallel to the spindle 527 of the third rod section 518.

[0119] The rod 615 is a triaxial ellipsoid and has three successive—a first, a second and a third—rod sections 616, 617, 618. When the two-part hinge device 611 is assembled, the first rod section 616 is supported in the hollow spherical housing bearing 653 in the first housing part 620. The first rod section 616 of the rod 615 has a ball head 652 which precisely fits the hollow spherical housing bearing 653. The hollow spherical housing bearing 653 functions as a clamping element 650. Adjustment of the rod 615 is effected at the second rod section 617, wherein the polygonal section 617a has surfaces in which the threaded holes 619, 619a are arranged, as described previously in
[0120] The rod 615 has two erosion notches 627, 627a along its longitudinal extension. This lends the suspension rod a bone-like profile, enabling savings in materials. The two erosion notches 627, 627a extend at least partly into the first and third rod sections 616, 618 and along the whole of the second rod section 617. The two erosion notches 627, 627a each have a flat area in the second rod section, where the spindles 622, 632 engage in the threaded holes 619, 619a. The spindles 622, 632 each engage partly in adjusting discs 622a, 632a to enable the adjustment. Alternatively, the respective spindles 622, 632 may be secured in the rod by means of a chemical securing means, by using Tuflok® or Nytemp® as a chemical locking agent, for example.
