DETAILED DESCRIPTION
[0043] The system according to the invention shown in FIG. 1 comprises a fastening bolt 10 which is illustrated in more detail in FIG. 2; in the present case, a screw bolt, with a shank portion having an outer thread 12 and a bolt head 14 which is enlarged in cross section in relation to the shank portion and has an engagement portion 16 for a tool for rotating the fastening bolt 10. In the exemplary embodiment shown in FIG. 1, the fastening bolt 10, which can be composed, for example, of metal, is held by its shank portion 12 in a hollow cylindrical holding sleeve 18 by means of frictional locking. The holding sleeve 18, which can be composed, for example, of plastic, is, on the other hand, held in a likewise hollow cylindrical first delimiting sleeve 20 by means of frictional locking. The first delimiting sleeve 20, which can be composed, for example, of metal, has a first contact flange 22 which is in the shape of a circular ring in the example shown. In the example shown, on the outer circumferential surface of the first delimiting sleeve 20, a plurality of latching projections 24 distributed over the circumference are formed. For the installation, the fastening bolt 10 together with the first delimiting sleeve 20 is inserted into a, for example, circular cylindrical through opening 28 of a first component 26 of a vehicle, such as a passenger vehicle or truck, as is shown, for example, in FIG. 17. For said installation, the fastening bolt 10 can be inserted with its outer thread 12, for example, only partially into the holding sleeve 18, as is illustrated in FIG. 17.
[0044] For the further installation, a second delimiting sleeve 30 is subsequently inserted from the opposite side of the first component 26, i.e. from below in FIG. 17. The second delimiting sleeve 30, which, for example, can likewise be composed of metal, is likewise hollow cylindrical and likewise has a second contact flange 32 in the shape of a circular ring. In the region of that end of the second delimiting sleeve which faces away from the second contact flange 32, an annular latching projection 34 is formed on the inner circumferential surface of the second delimiting sleeve 30. In the state inserted into the through opening 28 of the first component 26, said latching projection latches on the latching projections 24 of the first delimiting sleeve 20, as can be seen in FIG. 17. As a result, first and second delimiting sleeve 20, 30 are connected releasably to each other. In said state connected to each other, the first contact flange 22 lies with its inner side, which faces the second delimiting sleeve 30, against the first component 26 from a first side, from the upper side in FIG. 17. The second contact flange 32 of the second delimiting sleeve 30 lies with its inner side, which faces the first delimiting sleeve 20, against the first component 26, on the opposite side thereof, the lower side in FIG. 17. There can be a slight clamping here such that the system is held on the first component 26.
[0045] As can readily be seen in particular in FIG. 17, there is a radial distance between the outer circumferential surface of the second delimiting sleeve 30 and the inner circumferential surface of the through opening 28. Said distance is formed by the outer diameter of the second delimiting sleeve 30 being smaller than the inner diameter of the through opening 28. In the state shown in FIG. 17, the system is displaceable in the radial direction, optionally by overcoming the clamping, specifically in each radial direction in order to ensure comprehensive radial tolerance compensation. In this manner, the fastening bolt 10 can be aligned with its shank portion 12 with respect to a fastening receptacle of a second component (not illustrated specifically in the figures) of the vehicle and inserted into the fastening receptacle, in the example illustrated screwed into an inner thread of the fastening receptacle. The first component 26 can thereby be fastened to the second component.
[0046] It can also be seen in FIG. 17 that a plurality of elastic projections 36, in particular studs 36, are formed on the side, which faces the second contact flange 32 of the second delimiting sleeve 30, the lower side in FIG. 17, of the first component 26, against which the second contact flange 32 lies. Depending on the degree of deformation of the studs 36, axial tolerance compensation with respect to the distance between the mutually facing inner sides of first and second contact flange 22, 32 can thus also be provided.
[0047] FIGS. 6 and 7 illustrate a first delimiting sleeve 20 according to a further exemplary embodiment. In the system shown in FIG. 1, for example, said first delimiting sleeve 20 can be used instead of the first delimiting sleeve 20. It substantially corresponds in respect of its configuration to the first delimiting sleeve 20. Accordingly, it also comprises a first contact flange 22 in the shape of a circular ring. It differs from the first delimiting sleeve 20 shown in FIGS. 4 and 5 in respect of the latching means for latching to the second delimiting sleeve. The first delimiting sleeve 20 according to the exemplary embodiment shown in FIGS. 6 and 7 thus has an annular latching projection 24 on its outer circumferential surface. The first delimiting sleeve 20 shown in FIGS. 6 and 7 can be used, for example, together with the second delimiting sleeve 30, which is shown in FIGS. 9 and 10, according to a further exemplary embodiment in the system shown in FIG. 1. The second delimiting sleeve 30 shown in FIGS. 9 and 10 likewise in turn has a second contact flange 32 in the shape of a circular ring. In contrast to the second delimiting sleeve 30 shown in FIG. 3, the second delimiting sleeve 30 according to FIGS. 9 and 10 is, however, provided with a plurality of axial slots 38. In addition, its inner circumferential surface has an annularly encircling latching projection 34 interrupted merely by the slots 38. Furthermore, the inner side of the second contact flange 32, which inner side can be seen in FIG. 9 and lies against the first component 26 in the mounted state, is provided with a plurality of elastic projections 40 distributed over the circumference. The second delimiting sleeve 30 which is shown in FIGS. 9 and 10 can be composed, for example, of plastic. The first delimiting sleeve 20 from FIGS. 6 and 7 can be composed, for example, from metal. However, it could also be composed of plastic in the same manner as the first delimiting sleeve 30 from FIGS. 4 and 5. The same is true of the second delimiting sleeve 30.
[0048] The installation with the system as shown in FIG. 1, with the first delimiting sleeve 20 shown in FIGS. 6 and 7 and the second delimiting sleeve 30 shown in FIGS. 9 and 10 basically takes place in the same manner as explained above with respect to the first delimiting sleeve 20 and the second delimiting sleeve 30. In this case, however, the annular latching projection 24 of the first delimiting sleeve 20 and the annular latching projection 34 of the second delimiting sleeve 30 latch to each other, with the axial slots 38 providing sufficient elasticity of the second delimiting sleeve 30 for said latching. The system according to the invention shown in FIG. 1 using the first delimiting sleeve 20 and the second delimiting sleeve 30 is shown in FIG. 18 in the state mounted on a first component 26 with a through opening 28. As can be seen in FIG. 18, in this case the elastic projections 40 of the second contact flange 32 lie against the first component 26, the lower side of the first component 26 in FIG. 18. Said projections, like the elastic studs 36 explained with respect to FIG. 17, also provide tolerance compensation in the axial direction.
[0049] FIG. 8 illustrates a further exemplary embodiment of a holding sleeve 18 which, for example, can likewise be composed of plastic. Differently from the holding sleeve 18 from FIG. 1, the holding sleeve 18 has elastic latching elements 42 provided on its inner circumferential surface and elastic latching elements 44 provided on its outer circumferential surface. With said elastic latching elements 42 and 44, the holding sleeve 18 firstly latches on the shank portion of the fastening bolt 10 and secondly on the first delimiting sleeve 20, and therefore, in this case, the fastening bolt 10 is held in the first delimiting sleeve 20 via the holding sleeve 18 by latching or a form fit.
[0050] FIG. 11 illustrates a further exemplary embodiment of a system according to the invention. This very substantially corresponds to the exemplary embodiment shown in FIG. 1 and differs only in respect of the configuration of the holding sleeve. In the exemplary embodiment shown in FIG. 11, a holding sleeve 18 is provided which likewise has elastic latching means 44 on its outer circumferential surface and elastic latching means, which are concealed in FIG. 11, on its inner circumferential surface. With said elastic latching means, the holding sleeve 18 from FIG. 11 latches in turn firstly on the shank portion of the fastening bolt 10 and secondly on the inner surface of the first delimiting sleeve 20. While the holding sleeve 18 illustrated in FIG. 8 can be composed, for example, of plastic, the holding sleeve 18 shown in FIG. 11 can be composed, for example, of metal.
[0051] FIG. 12 illustrates a further exemplary embodiment of a system according to the invention which differs from the exemplary embodiment shown in FIG. 1 in respect of the configuration of the fastening bolt and the first delimiting sleeve. The fastening bolt 10 used in the case of the system from FIG. 12 can be seen more precisely in FIGS. 13 and 14. It in turn has a shank portion with an outer thread 12, not illustrated specifically in FIGS. 12 to 14, and a bolt head 14 which is enlarged in cross section in relation to the shank portion and has an engagement portion 16 for a rotational tool. In addition, an annularly encircling latching projection 46 is formed between the outer thread 12 and the bolt head 14. With said latching projection, the fastening bolt 10 is held in a first delimiting sleeve 20, which is illustrated in FIGS. 15 and 16, according to a further exemplary embodiment. Said first delimiting sleeve 20 in turn has a first contact flange 22 in the shape of a circular ring. In addition, it has a plurality of latching projections 24 on its outer circumferential surface. Furthermore, in the region of its end facing the first contact flange 22, the first delimiting sleeve 20 has a plurality of latching projections 48 on its inner circumferential surface. Said latching projections latch on the latching projection 46 of the fastening bolt 10, as can be seen in particular in FIG. 12. The fastening bolt 10 is thereby also held in a preassembly position on the first delimiting sleeve 20 without an additional holding sleeve. The structural outlay of the system is thereby reduced further.
[0052] For the installation, the fastening bolt 10 with the first delimiting sleeve 20 in the preassembled state shown in FIG. 12 is inserted into the through opening 28 of the first component 30 and the second delimiting sleeve 30 is inserted into the through opening 28 from the opposite side, as has basically been explained above with respect to the system with reference to FIG. 17. The latching projections 24 of the first delimiting sleeve 20 latch here with the annular latching projection 24 of the second delimiting sleeve 30, and the first contact flange 22 of the first delimiting sleeve 20 and the second contact flange 32 of the second delimiting sleeve 30 come in turn to lie against the first component 26 from opposite sides.
[0053] The exemplary embodiments can be combined with one another here in basically any way. A common feature of all of the exemplary embodiments is that they provide comprehensive radial tolerance compensation and optionally also axial tolerance compensation while being simple to install.
