Description

[0001] The present invention relates to an alignment system for aligning a first component of a motor vehicle with a second component of the motor vehicle. The invention further relates to a motor vehicle with an alignment system of the generic type and to a method for mounting a first component of a motor vehicle with a second component of the motor vehicle.

[0002] It is known to use an alignment system for the automated assembly of a strut to a vehicle body. One such alignment system is known, for example, from document DE 10 2018 211 525 A1. For alignment purposes, the strut bearings of the struts have, for example, alignment cones which can be inserted into centering bores of a strut mount in the body when the strut and vehicle body are joined. The alignment cones are, for example, made of aluminum and cast onto the strut bearing. Document DE 10 2020 213 879 A1 discloses another alignment system.

[0003] During the alignment process, the alignment cones sometimes seize on the burrs of the centering holes. Since the centering holes can only be punched from top to bottom for manufacturing reasons, the burrs are located on the side of the strut bearing. For automatic bolting, tight fits of the alignment cones' shoulders to the body-in-white alignment holes are also required, ensuring a play-free and stress-free fit. When the alignment cones seize, the shoulders are often further deformed and enlarged by material being pushed onto them, causing the tight fits required for a play-free fit to jam during initial installation.

[0004] To avoid process errors—such as a component not fitting properly on the joining surface—the locating holes in the body-in-white must be enlarged, compromising joining precision and contradicting the results of the tolerance chain analysis. Both of these factors reduce the process reliability of the automated strut assembly and the precision of the predefined camber values. Furthermore, the body's weight during the joining process is often insufficient to overcome the joining resistance caused by the raised aluminum ridge of the jammed alignment mandrel and to press the strut bearings into a uniquely aligned position with the bearing perfectly parallel to the body-in-white. During the joining process, the body is even lifted several centimeters from the chassis frame.

[0005] It is therefore an object of the present invention to eliminate, or at least partially eliminate, the disadvantages described above in an alignment system for aligning a first component of a motor vehicle to a second component of the motor vehicle. In particular, it is an object of the present invention to provide an alignment system, a motor vehicle, and a method for mounting a first component of a motor vehicle to a second component of the motor vehicle that avoid material corrosion on the alignment elements in a simple and cost-effective manner and thus ensure more reliable alignment of the components.

[0006] The aforementioned problem is solved by the claims. Accordingly, the problem is solved by an alignment system for aligning a first component of a motor vehicle on a second component of the motor vehicle, having the features of independent claim 1; by a motor vehicle having the features of dependent claim 9; by an alignment system having the features of dependent claim 10; and by a method for mounting a first component of a motor vehicle on a second component of the motor vehicle, having the features of dependent claim 11. Further features and details of the invention will become apparent from the dependent claims, the description, and the drawings.Features and details described in connection with the alignment systems according to the invention naturally also apply in connection with the motor vehicle according to the invention and the method according to the invention, and vice versa, so that with regard to the disclosure of the individual aspects of the invention, mutual reference is always made or can be made.

[0007] According to a first aspect of the invention, the problem is solved by an alignment system for aligning a first component of a motor vehicle with a second component of the motor vehicle. The alignment system comprises a first alignment means arranged on the first component with a first passage, a second alignment means arranged on the second component with a second insertion, and a third alignment means formed separately from the first and second components. The third alignment means has an end region for passing through the first passage and for insertion into the second insertion, an intermediate region for insertion into the first passage, and a head region for positively limiting insertion into the first passage. The intermediate region is designed for aligning the third alignment means with the first alignment means.The end area is designed to align the third alignment device with the second alignment device.

[0008] The first component can, for example, be designed as a strut mount in the body shell or chassis of a motor vehicle. The second component can, for example, be designed as a strut bearing for a strut in the suspension of a motor vehicle.

[0009] The first alignment means is arranged on the first component and has the first through-hole. For the purposes of this invention, a through-hole is understood to be, for example, a through-hole. The first through-hole can be, for example, a round hole or an oblong hole. Preferably, the first component has several first alignment means, which are arranged distributed over the first component. The first alignment means are preferably arranged uniformly over the first component, preferably with respect to a surface of the first component. The first through-hole has a diameter that is larger than the diameter of the end region of the third alignment means and smaller than the head region of the third alignment means. The first through-hole can be produced in the first component, for example, by drilling, milling, punching, or the like.

[0010] The second alignment means is arranged on the second component and has a second entry point. For the purposes of this invention, an entry point is understood to be, for example, a through hole or a blind hole. The second entry point is preferably designed as a round hole. Preferably, the second component has several second alignment means, which are arranged distributed over the second component. The second alignment means are preferably arranged evenly distributed over the second component, preferably with respect to a surface of the second component. The second entry point has a diameter that preferably corresponds to the diameter of the end region of the third alignment means, so that the end region can be inserted into the second entry point. The second entry point can be produced in the second component, for example, by drilling, milling, punching, or the like.Alternatively, the second entry can also be formed in a bushing which is fixed to the second component, for example by welding, pressing, forming, or the like. A bushing can, for example, be arranged in a second opening of the second component. Preferably, the bushing has external dimensions on a side of the second component facing away from the first component that are larger than the diameter of the second opening and / or project laterally beyond the second opening, so that slippage of the bushing through the second opening in at least one direction is prevented by a positive locking mechanism.

[0011] The third alignment element is designed separately from the first and second components. This means, for example, that the third alignment element can be provided separately from the first and second components. The third alignment element is preferably designed as a bolt and is preferably rotationally symmetrical or at least substantially rotationally symmetrical. Within the scope of the invention, a substantially rotationally symmetrical design is understood to be a design which may include additional non-rotationally symmetrical elements, such as a positive locking lug for a tool or the like. The third alignment element comprises the end region, the head region, and the intermediate region arranged between the end region and the head region. The head region preferably has a larger outer diameter than the intermediate region. The intermediate region preferably has a larger outer diameter than the end region.The end section has a smaller outer diameter than the first opening and can therefore pass completely through the first opening. The head section has a larger outer diameter than the first opening. Alternatively or additionally, the third alignment element can also be prevented from slipping through the first opening by means of a washer, which can also be designed as a separate component, but which, for the sake of simplicity, is considered part of the head section within the scope of the invention.

[0012] The third alignment device is designed to perform several technical functions simultaneously. The end section of the third alignment device is designed to align it with the second component in conjunction with the second alignment device. The intermediate section of the third alignment device is designed to align it with the first component in conjunction with the first alignment device. In this way, the third alignment device allows the first component to be aligned with the second component. Preferably, the third alignment device is also designed to fasten the first component to the second component. The third alignment device is preferably made of steel or a material with a higher strength than aluminum.

[0013] An alignment system according to the invention has the advantage over conventional alignment systems that the automatic alignment of two components is improved using simple means and in a cost-effective manner. The use of the third alignment element reduces interactions with burrs on the first alignment element, especially since the third alignment element can be joined to the first on its burr-free side. This also prevents material corrosion during the alignment process.

[0014] According to a preferred embodiment of the invention, an alignment system may be provided in such a way that the second alignment means has an internal thread, wherein the end region has an external thread compatible with the internal thread of the second alignment means. The internal thread may, for example, be cut directly into the second entry of the second component. Alternatively, the internal thread may be cut into the second entry, wherein the second entry is formed in a bushing. The bushing is attached to the second component, for example, by welding, pressing, forming, or the like. A bushing may, for example, be arranged in a second passage of the second component.Preferably, the bushing on the side of the second component facing away from the first component has external dimensions that are larger than the diameter of the second through-hole and / or project laterally beyond the second through-hole, so that slippage of the bushing through the second through-hole in at least one direction is prevented by a positive locking mechanism. The internal and external threads are preferably designed as fine threads, so that screwing the third alignment element to the second alignment element generates a particularly high contact pressure between the first and second components. The force required to tighten the third alignment element is thus reduced. A rotary motion of the third alignment element when screwed into the internal thread promotes sliding alignment. Furthermore, this better prevents the third alignment element from seizing on the first alignment element.Furthermore, the force required to align the first component with the second component can be provided via the screwing process and is therefore independent of the weight of the first component, which, in known processes, is lowered onto the second component. This has the advantage that the alignment and assembly of the first component with the second component can be further improved using simple means and in a cost-effective manner.

[0015] Preferably, the second alignment element has a widening area in the joining direction upstream of the internal thread for aligning its end with the internal thread. A widening area is understood to be, for example, a circumferential chamfer or the like. The widening area is therefore preferably truncated conically shaped. The widening area allows for a greater positional deviation of the third longitudinal axis relative to the second longitudinal axis when aligning the third alignment element with the second alignment element. During alignment, the end of the third alignment element only needs to enter the widening area and is aligned by it towards the second longitudinal axis as it moves further into the second insertion point.Preferably, the expansion area has a maximum diameter that is larger than the diameter or width of the first through-hole, so that burrs from the first through-hole can be accommodated by the expansion area during assembly. This has the advantage that the alignment and assembly of the first component with the second component is further improved in a simple and cost-effective manner.

[0016] According to the invention, it is preferred that the end region has a first taper pointing away from the intermediate region for aligning the third alignment means with the second alignment means. The first taper preferably forms the end of the third alignment means. Preferably, the taper is designed as a pointed cone or truncated cone. Alternatively, the taper can also be designed as a rounded section. The taper allows for compensation of positional tolerances between the third alignment means and the second alignment means during the alignment process. A third longitudinal axis of the third alignment means can thus be arranged next to a second longitudinal axis of the second alignment means, whereby it must be ensured that the end of the third alignment means points into the second insertion when moving towards the second component and can thus be received into it.The tapered design allows for a one-sided contact between the end of the third alignment element and the second alignment element. This, in turn, creates a lateral force that aligns the third longitudinal axis with the second longitudinal axis when the third alignment element is moved further into the second insertion point. This offers the advantage of further improving the alignment and assembly of the first component with the second component using simple and cost-effective means.

[0017] In a particularly preferred embodiment of the invention, the intermediate section has a second taper pointing towards the end section for aligning the third alignment element with the first alignment element. The second taper is, for example, designed as a circumferential chamfer or the like. Accordingly, the second taper is preferably truncated conically shaped. The second taper allows for a greater positional deviation of the third longitudinal axis relative to the first longitudinal axis when aligning the third alignment element with the first alignment element. During alignment, the tapered portion of the intermediate section of the third alignment element only needs to enter the first opening and is aligned by it towards the first longitudinal axis as it moves further into the opening.This has the advantage that the alignment and assembly of the first component with the second component can be further improved using simple means and in a cost-effective manner.

[0018] Preferably, the intermediate section, in addition to the head area, has a fitting shoulder adapted to the first through-hole. Particularly preferably, the second taper merges smoothly with the fitting shoulder, thus improving alignment of the fitting shoulder with the first through-hole. Within the scope of the invention, adaptation of the fitting shoulder to the first through-hole means that the fitting shoulder has a diameter corresponding to the diameter of the first through-hole. In this case, relative movement on a plane can be prevented by a positive locking mechanism. If the first through-hole is designed as an elongated slot, the fitting shoulder preferably corresponds to the width of the elongated slot. In this case, relative movement transverse to the longitudinal extent of the elongated slot can be prevented by a positive locking mechanism. If there are multiple first through-holes, the fitting shoulder preferably corresponds to the diameter of the smallest first through-hole and / or the width of the elongated slot.The fitting shoulder allows for a defined position of the third alignment element relative to the first during the alignment and assembly process. This has the advantage of further improving the alignment and assembly of the first component with the second component in a simple and cost-effective manner.

[0019] According to a preferred embodiment of the invention, the alignment system comprises three first alignment means, three second alignment means, and three third alignment means. Preferably, the first alignment means are arranged on the first component and the second alignment means are arranged on the second component such that the first alignment means can be simultaneously aligned with one of the second alignment means at a time. Furthermore, preferably two of the first alignment means are designed to compensate for manufacturing tolerances and to prevent static overdetermination during alignment. This has the advantage that the alignment and assembly of the first component with the second component is further improved in a simple and cost-effective manner.

[0020] The first three alignment means preferably have one elongated hole and two round holes with different diameters. The elongated hole preferably has a width corresponding to the diameter of the smaller round hole. This diameter preferably corresponds to the diameter of any fitting shoulder of the third alignment means. A longitudinal axis of the elongated hole preferably passes through the center point of the smaller round hole. Alternatively, the first three alignment means have three elongated holes, with two of the three elongated holes arranged parallel to each other. The three elongated holes preferably have a width corresponding to the diameter of any fitting shoulder of the third alignment means. In this case, it is preferred that the third elongated hole is arranged at a 90° angle to the parallel elongated holes. The parallel elongated holes preferably have a common longitudinal axis.Alternatively, the parallel elongated holes have longitudinal axes running side by side. It is preferred that one of these longitudinal axes passes through the third elongated hole, preferably its center. In all cases, it is preferred that the three first alignment means are spaced apart from one another. This has the advantage that the alignment and assembly of the first component with the second component can be further improved in a simple and cost-effective manner.

[0021] According to a second aspect of the invention, the problem is solved by an alignment system for aligning a first component of a motor vehicle with a second component of the motor vehicle. The alignment system comprises a first alignment element with a first through-hole arranged on the first component, a second alignment element with an external thread arranged on the second component, and a third alignment element with an internal thread, separate from the first and second components. The second alignment element has an end section for passing through the first through-hole. The second alignment element or the third alignment element has an intermediate section for insertion into the first through-hole. The third alignment element has a head section for contacting the first through-hole.The intermediate area is designed for alignment with the first alignment device, and the end area is designed for alignment of the third alignment device with the second alignment device.

[0022] Preferably, the third alignment element has a widening area in the joining direction upstream of the internal thread for aligning its end section with the internal thread. More preferably, the end section has a first taper pointing away from the second component for aligning the third alignment element with the second alignment element. Preferably, the intermediate section has a second taper pointing towards the end section for aligning the first alignment element with the second or third alignment element. More preferably, the intermediate section has a shoulder adapted to the first through-hole in addition to the second taper. The alignment system most preferably comprises three first alignment elements, three second alignment elements, and three third alignment elements. Preferably, the three first alignment elements have one slotted hole and two round holes with different diameters.Alternatively, it is preferred that the three first alignment means have three elongated holes, wherein two of the three elongated holes are arranged parallel to each other.

[0023] The alignment system according to the second aspect of the invention offers all the advantages already described for an alignment system according to the first aspect of the invention. Accordingly, the alignment system according to the invention has the advantage over conventional alignment systems that the automatic alignment of two components is improved using simple means and in a cost-effective manner. The use of the third alignment element reduces interactions with burrs on the first alignment element, especially since the third alignment element can be joined to the first on its burr-free side. Thus, material corrosion during the alignment process can also be prevented.

[0024] According to a third aspect of the invention, the problem is solved by a motor vehicle. The motor vehicle comprises a first component and a second component. According to the invention, the motor vehicle has an alignment system according to the invention, by means of which the first component is aligned and fastened to the second component. Accordingly, the first alignment means is arranged on the first component and the second alignment means on the second component. Preferably, the first component is fixed to the second component by means of the third alignment means.

[0025] The motor vehicle according to the invention offers all the advantages already described for an alignment system according to the first and second aspects of the invention. Accordingly, the motor vehicle according to the invention has the advantage over conventional motor vehicles that the automatic alignment of two components is improved using simple and cost-effective means. The use of the third alignment element reduces interactions with burrs on the first alignment element, especially since the third alignment element can be joined to the first on its burr-free side. Thus, material corrosion during the alignment process can also be prevented.

[0026] According to a fourth aspect of the invention, the problem is solved by a method for mounting a first component of a motor vehicle to a second component of the motor vehicle using an alignment system according to the invention. The method comprises: - Arranging the first component on the second component such that the first alignment means of the first component are each adjacent to a second alignment means of the second component, - Carrying out the end sections of the third alignment device by the first alignment device, - Interaction of the end areas with the second alignment means, - further movement of the end areas into the second alignment devices, whereby this results in a lateral alignment of the second alignment devices to the third alignment devices as well as a movement of the second component towards the first component, - Moving the intermediate sections of the third alignment tools into the first alignment tools in such a way that the third alignment tools are aligned with the first alignment tools, and - Positioning the head areas of the third alignment device on the first component next to the first alignment device.

[0027] The first component, for example, is a strut mount for the body shell of a motor vehicle. The strut mount is preferably supplied as an integral part of the body shell, together with the body shell itself. The second component, for example, is a strut bearing for a strut of the motor vehicle's suspension. The strut bearing is preferably mounted on the strut and supplied together with the strut. The third component, preferably special alignment screws, is supplied.

[0028] The first component is initially roughly aligned with the second component. This rough alignment is achieved by arranging the first alignment means of the first component adjacent to a second alignment means of the second component. In this alignment state, it is ensured that a final, more precise alignment of the first component with the second component can be reliably achieved using the alignment system according to the invention. This means that in this state, at least one third alignment means can be brought into engagement with a first alignment means and a second alignment means, and the further third alignment means can each be brought into engagement with a first alignment means and a second alignment means at least by means of an alignment process by the one third alignment means.Preferably, the coarse alignment is carried out such that all third alignment means can be brought into engagement with one of the first alignment means and one of the second alignment means. For this, preferably only a purely translational movement of the third alignment means is required.

[0029] The end regions of the third alignment means are passed through the first alignment means, preferably by a translational movement, and preferably through first openings provided for this purpose in the first alignment means. This passage is preferably carried out such that the intermediate regions of the third alignment means are located in the first openings of the first alignment means, and the head regions of the third alignment means are arranged adjacent to the first openings.

[0030] By passing the end sections through the first feedthroughs, the end sections of the third alignment means engage with the second insertions of the second alignment means. This preferably occurs by an additional rotation of the third alignment means about the third longitudinal axes. In the context of the invention, engagement means, for example, that an external thread of the end section engages with an internal thread of the second insertion, such that by rotating the third alignment means about the third longitudinal axis, the third alignment means is drawn into the second insertion. The third longitudinal axis aligns with the adjacent second longitudinal axis. When the end sections engage with the second insertions, the third longitudinal axis may form an angle with the adjacent first longitudinal axis.The engagement of the end areas of the third alignment devices with the second introductions can occur simultaneously with all third alignment devices or at different times.

[0031] By further moving the intermediate sections of the third alignment means into the first alignment means, the third alignment means are aligned with the first alignment means. This is achieved by one-sided contact between the intermediate sections and the first alignment means, which allows a transverse force to be exerted between the first component and the third alignment means. This alignment preferably takes place such that the third longitudinal axis is arranged parallel to the first longitudinal axis, preferably coaxially.

[0032] Finally, the heads of the third alignment devices are placed next to the first alignment devices on the first component. By further tightening the third alignment devices, which are designed as special screws, for example, the first component can be clamped to the second component, thus preventing any relative movement of the first component to the second component by means of a force-fit connection.

[0033] The method according to the invention offers all the advantages already described for an alignment system according to the first and second aspects of the invention, as well as for a motor vehicle according to the third aspect of the invention. Accordingly, the method according to the invention has the advantage over conventional methods that the automatic alignment of two components is improved using simple means and in a cost-effective manner. By using the third alignment element, interactions with burrs on the first alignment element can be reduced, especially since the third alignment element can be joined to the first alignment element on its burr-free side. Thus, material corrosion during the alignment process can also be prevented.

[0034] An alignment system, a motor vehicle, and a method according to the invention are explained in more detail below with reference to the drawings. The drawings schematically show: Fig. 1 in a sectional view a first state of a preferred first embodiment of an alignment system according to the invention during the execution of a method according to a preferred embodiment of the invention, Fig. 2 in a sectional view a second state of the alignment system Fig. 1 during the execution of the procedure, Fig. 3 in a sectional view a third state of the alignment system Fig. 1 during the execution of the procedure, Fig. 4 in a sectional view a fourth state of the alignment system Fig. 1 during the execution of the procedure, Fig. 5 in a sectional view a fifth state of the alignment system Fig. 1 during the execution of the procedure, Fig. 6 in a top view several first alignment means according to the preferred first embodiment of the invention, Fig. 7 in a top view several first alignment means according to a preferred second embodiment of the invention, Fig. 8 in a top view several first alignment means according to a preferred third embodiment of the invention, Fig. 9 in a sectional view an alignment system according to a preferred fourth embodiment of the invention, Fig. 10 in a sectional view an alignment system according to a preferred fifth embodiment of the invention, and Fig. 11 in a side view a preferred embodiment of a motor vehicle according to the invention.

[0035] Elements with the same function and mode of operation are in the Fig. Numbers 1 to 11 are each labelled with the same reference numerals.

[0036] In Fig. Figure 1 schematically depicts a first state of a preferred first embodiment of an alignment system 1 according to the invention during the execution of a method according to a preferred embodiment of the invention. The alignment system 1 comprises a first component 2 with several first alignment means 5 designed as first through-holes 6, a second component 4 with several second alignment means 7 designed as second through-holes 8, and several third alignment means 9 designed as special screws. The third alignment means 9 have a head region 12 with an external hexagon, an intermediate region 11, and an end region 10. In this example, three first alignment means 5 and consequently three second alignment means 7, as well as three third alignment means 9, are provided.

[0037] The end section 10 has a first taper 16 extending away from the intermediate section 11, which is shaped like a point and forms one end of the third alignment element 9. The intermediate section 11 has an external thread 14 extending from the end section 10 towards the head section 12. Between the head section 12 and the external thread 14, the intermediate section 11 has a second taper 17 extending towards the end section 10. Between the second taper 17 and the head section 12, the intermediate section 11 has a shoulder 18.

[0038] The first through-holes 6 are designed to guide the end section 10 and the intermediate section 11 in the joining direction F. Contact between the second tapered section 17 and the first through-hole 6 enables the first component 2 to be aligned with the third alignment means 9. At least one of the first through-holes 6 is designed to precisely receive the fitting shoulder 18. Preferably, at least one of the first through-holes 6 is designed to fully or two-dimensionally receive the fitting shoulder 18 precisely, and / or at least one of the first through-holes 6 is designed to laterally or one-dimensionally receive the fitting shoulder 18 precisely. Thus, a defined position of the first component 2 relative to the third alignment means 9 can be achieved.

[0039] The second inlets 8 have a widening section 15 pointing towards the first component 2 and a bore with an internal thread 13 located at the narrow end of the widening section 15. The widening section 15 is designed to receive the end section 10 of the third alignment means 9 and to guide the third alignment means 9 to the internal thread 13. In the first state shown, the third alignment means 9 are arranged next to the first component 2. The second component 4 is arranged obliquely below the first component 2 such that alignment via the third alignment means 9 is ensured.

[0040] Fig. Figure 2 shows a second state of the alignment system 1. Fig. 1. The execution of the procedure is shown schematically in a sectional view. In the second state, the third alignment elements 9 are further moved in the joining direction F and are each partially arranged in the first feedthroughs 6 and in the second insertions 8. There is still no contact between the third alignment elements 9 and the second alignment elements 7.

[0041] In Fig. 3 is a third state of the alignment system 1 from Fig. Figure 1 shows the execution of the procedure in a sectional view. In the third state, the external threads 14 of the third alignment means 9 are engaged with the internal threads 13 of the second alignment means 7. Thus, the third alignment means 9 are aligned coaxially with the second alignment means 7.

[0042] Furthermore, the second tapered sections 17 contact a lateral edge area of ​​the first feedthroughs 6. By further screwing the third alignment means 9 into the second alignment means 7 and thus further moving the third alignment means 9 in joining direction F, the first component 2 is aligned with the third alignment means 9 and the second component 4.

[0043] Fig. Figure 4 shows a fourth state of the alignment system 1. Fig. 1. The process is schematically illustrated in a sectional view. In the fourth state, the second component 4 is almost finally aligned with the first component 2. The third alignment devices 9 are not yet fully screwed into the second alignment devices 7.

[0044] In Fig. 5 is a fifth state of alignment system 1 from Fig. Figure 1 schematically illustrates the execution of the procedure in a sectional view. In the fifth state, the second component 4 is finally aligned with the first component 2. The third alignment devices 9 are fully screwed into the second alignment devices 7, so that the first component 2 is precisely fixed to the second component 4. The fitting shoulders 18 are arranged in the first through-holes 6 and thus define a position of at least one of the third alignment devices 9 relative to the first component 2. To avoid static overdetermination, which could lead to unwanted stresses or assembly problems due to possible manufacturing tolerances, the fitting shoulder 18 of one of the third alignment devices 9 additionally defines a position relative to the first component 2 with one degree of freedom perpendicular to the joining direction F.The fitting shoulder 18 of a further third alignment means 9 preferably has two degrees of freedom transverse to the joining direction F in order to avoid static overdetermination with respect to the first component 2.

[0045] Fig. Figure 6 schematically shows several first alignment means 5 according to the preferred first embodiment of the invention in a top view. One first alignment means 5 has a first passage 6 designed as a round hole with a diameter corresponding to the diameter of the fitting shoulder 18. A main part of the alignment process can thus be carried out via this first alignment means 5, since it allows no play with the third alignment means 9. Another first alignment means 5 has a first passage 6 designed as an elongated hole, wherein the width of the elongated hole corresponds to the diameter of the fitting shoulder 18. Thus, one degree of freedom in the longitudinal direction of the elongated hole is ensured during alignment. A further first alignment means 5 has a first passage 6 designed as a round hole with a larger diameter than the fitting shoulder 18. Thus, two degrees of freedom are ensured during alignment.
