Description

Technical Field

[0001] The invention relates to a support component for a motor vehicle body according to the preamble of claim 1. The invention also relates to a method for producing a support component for a motor vehicle body according to the preamble of claim 10. Background Art

[0002] The general prior art has already disclosed a supporting part for a motor vehicle body sufficiently. Such a supporting part is configured as a casting, for example, and has, for example, a rib structure for reinforcement, which has a plurality of ribs. Summary of the invention

[0003] The object of the present invention is to provide a support component for a motor vehicle body and a method for producing a support component for a motor vehicle body, in which the weight of the support component can be kept particularly low.

[0004] This object is achieved according to the invention by a support component for a motor vehicle body having the features of claim 1 and by a method for producing a support component for a motor vehicle body having the features of claim 10. Advantageous embodiments of the invention are the subject of the dependent claims and the description.

[0005] A first aspect of the invention relates to a support for a vehicle body. A vehicle body can be understood in particular as a vehicle body for a vehicle. The vehicle body is preferably designed as a self-supporting vehicle body. The vehicle is designed, for example, as a passenger car, a commercial vehicle or a truck. The support can in particular be referred to as a support element.

[0006] The carrier is configured as a casting, in particular as a die-casting. In other words, the carrier is manufactured or can be manufactured, in particular at least mostly or completely, by means of casting, in particular by means of die-casting.

[0007] The carrier is reinforced at least in one length region by at least one rib structure, which has a plurality of ribs. In other words, a rib structure is provided at least in the length region, which has a plurality of or a plurality of ribs. The carrier is therefore configured as a ribbed casting, in particular at least in the length region.

[0008] The ribs are in particular directly connected to one another at least in the region of at least one rib intersection. In other words, at least two ribs intersect in the region of the rib intersection or at the rib intersection. Thus, the rib intersection is formed, for example, by intersecting or intersecting ribs (in particular at least partially or completely). The rib intersection can in particular be referred to as a rib intersection. The rib intersection can in particular be understood as an intersection region or intersection of the ribs. The rib intersection is preferably part of the rib structure.

[0009] In order to keep the weight of the support, in particular the vehicle body, particularly low, it is provided according to the invention that the rib intersection has a receiving opening in which a screw element for fixing at least one component (in particular constructed separately from the support) to the support is (in particular at least indirectly or directly) fixed or can be fixed. In other words, the screw element is arranged or can be arranged in the receiving opening in order to fix the component to the support. This means that the screw element is fixed or can be fixed in the receiving opening in order to fix the component to the support (in particular via the screw element or the receiving opening). The connection of the component to the support can thus be achieved by means of the screw element.

[0010] The screw element can be understood in particular as a fixing element, which is preferably designed as a screw or in a screw-like manner. The screw element is preferably designed separately from the carrier. The component is preferably a component of a motor vehicle, in particular a component of a motor vehicle body. Therefore, the component can be understood in particular as a structural element or component of a motor vehicle, in particular a body. For example, the component is designed as an accessory, in particular a covering or a covering component.

[0011] The invention is based in particular on the following recognition and consideration: It is conceivable in principle to close a support part or a casting (which may have an open contour) by means of a closing plate, for example made of steel. In this context, it is conceivable in principle to provide, in particular weld, a screw element, which is designed, for example, as a ignition screw, on or to the closing plate. This may have a negative effect on the weight of the support part or the vehicle body, since the closing plate would in particular increase the weight of the support part or the vehicle body.

[0012] In contrast, in the carrier according to the invention, the bolting element is arranged in the receiving opening and thus at or in the rib intersection. As a result, a closing plate can be omitted, so that the weight of the carrier, in particular the vehicle body, can be kept particularly light. This means that in castings, in particular die castings, the entire or particularly high weight potential of, for example, aluminum die castings can be fully utilized. Overall, it can be seen that in the carrier according to the invention, instead of welding the bolting element to the surface of the closing element, the bolting element can be connected to the carrier in the receiving opening and thus via the rib intersection or rib structure, i.e. without a closing plate. The component can thus be connected to the carrier (in particular directly) without a closing plate.

[0013] For example, a material accumulation is provided in the region of the rib intersection, which is preferably designed to be particularly small or particularly thin. For example, the receiving opening is at least partially provided in the region of the material accumulation or is at least partially formed by the material accumulation. The material accumulation can be designed to be as small or as thin as a rib intersection without a receiving opening, i.e. without a receiving opening. As a result, the weight of the support can be kept particularly light. Alternatively, the material accumulation can be designed to be only slightly stronger or thicker than a rib intersection without a receiving opening. As a result, the weight of the support can be kept particularly light.

[0014] Preferably, the carrier or casting has an open cross section at least in the length region. This means that the cross section of the carrier is not closed at least in the length region. In other words, the carrier is configured to be open at least on one side of the carrier in the length region.

[0015] In another embodiment, it is provided that at least one outer wall of the carrier at least partially, in particular directly, defines the accommodating cavity in the length region. In other words, the accommodating cavity is at least partially, in particular directly covered or surrounded by the outer wall. Preferably, the rib structure is especially at least partially, mostly or completely arranged within the outer wall. In other words, the rib structure is at least partially located within the carrier, in particular within the cross section. This means that the rib structure extends especially at least partially, mostly or completely within the open cross section. As a result, the rigidity of the carrier, in particular the vehicle body, can be particularly increased. In particular, the weight of the carrier can be kept particularly light. For example, the rib structure extends at least between two (in particular opposite) wall areas of the open cross section.

[0016] The longitudinal axis of the receiving opening preferably extends perpendicularly to the open side of the carrier or the length region. In other words, the stretching direction of the rib structure extends, for example, at least substantially perpendicularly to the open side of the casting.

[0017] In another design, it is provided that the outer wall of the support is at least substantially, in particular mostly or completely, configured as a U-shape or an L-shape in the length region. In other words, the support has at least a mostly configured U-shaped or L-shaped cross section in the length region. This means that the outer wall or the open cross section is configured as a U-shaped profile or an L-shaped profile. "The outer wall of the support is at least substantially configured as a U-shaped in the length region" can be understood in particular that the receiving portion of the support is at least substantially configured as a box-shaped profile or a box-shaped in the length region. As a result, the weight of the support, in particular the vehicle body, can be kept particularly light. In addition, the support can be manufactured particularly inexpensively, in particular by means of casting.

[0018] Preferably, it is provided that the rib structure extends within the U-shaped profile or the U-shaped cross section. This can particularly increase the rigidity of the support component, in particular the vehicle body. In particular, the weight of the support component can be kept particularly light.

[0019] In another embodiment, it is provided that the screw element is fixed or can be fixed or can be fixed in the receiving opening, in particular directly, by means of a thread, in particular a self-tapping thread. In other words, the screw element is connected to the carrier, in particular directly, by means of a threaded connection. This means that the screw element is screwed or can be screwed into the receiving opening, in particular by means of a thread. Therefore, the screw element is preferably designed as a screw. As a result, the screw element can be fixed to the carrier in a particularly reliable and / or particularly cost-effective manner.

[0020] “The bolt element is fixed or can be fixed in the receiving opening by means of a self-tapping thread” can be understood in particular to mean that the thread of the bolt element is configured as a self-tapping thread. “Self-tapping thread” can be understood in particular as a cutting thread. This means that the self-tapping thread is configured to cut a thread corresponding to the thread of the bolt element in the wall of the receiving opening or the casting that at least partially defines the receiving opening when the bolt element is screwed or screwed into the receiving opening. Therefore, the receiving opening or the casting, for example, has no thread before the bolt element is screwed or screwed in, and the receiving opening has a thread after the bolt element is screwed or screwed in. In particular, a threaded connection can be formed in which the thread of the bolt element is screwed into the thread of the receiving opening or into the thread of the wall that defines the receiving opening. In other words, the bolt element can be screwed or screwed into the receiving opening by self-tapping of the thread. Therefore, the support or the vehicle body can be manufactured particularly cost-effectively, in particular by being able to omit separate processing in the receiving opening, in particular cutting of the thread.

[0021] It is preferably provided that the screw element has a thread on the side facing away from the receiving opening, which thread is different from the thread of the screw element and is in particular referred to as the second thread, by means of which the component is (for example directly) fixed or can be fixed to the support, in particular to the bolt. In other words, the thread of the screw element, in particular the thread referred to as the first thread, is arranged on the side facing the receiving opening, and the second thread is arranged on the side facing away from the receiving opening, by means of which the component is (preferably directly) connected or can be connected to the support, in particular to the bolt. The screw element is thus designed, for example, as a stud. As a result, the component can be fixed to the support in a particularly cost-effective manner by means of the screw element.

[0022] In another embodiment, it is provided that the bolt element has a drive element arranged between the threads, in particular between the threads and the second thread, by means of which a torque, in particular a mounting torque, can be applied to the bolt element in order to fix the bolt element to the carrier, in particular to screw the bolt element into the receiving opening. In other words, a torque, in particular a mounting torque, can be applied to the bolt element by the drive element in order to fix the bolt element to the carrier, in particular in order to screw the bolt element, in particular the thread, into the receiving opening. As a result, the torque can be applied to the bolt element particularly advantageously, so that the bolt element can be connected to the carrier in a particularly cost-effective manner. For example, the drive element is arranged centrally in the axial direction of the bolt, i.e., in the middle of the bolt. The drive element is, for example, constructed as a hexagon, in particular as an outer hexagon.

[0023] In another design, it is provided that the rib intersection has a boss (Dom), in which the receiving opening is at least partially or completely arranged. In other words, the receiving opening extends at least partially, in particular completely, within the boss, which is at least partially formed by the rib intersection. Therefore, the receiving opening is arranged, for example, in the area of ​​the material accumulation part in the form of a boss. As a result, the receiving opening can be arranged on the support in a particularly space-saving manner, so that, for example, the structural space of the support can be designed particularly advantageously. For example, the material accumulation part is particularly small. In particular, the thickness of the material accumulation part can be designed, for example, to be the same as that of a boss without a receiving opening or only slightly thicker than a boss without a receiving opening. As a result, the weight of the support can be kept particularly light.

[0024] The boss is preferably designed as an ejector boss. The ejector boss is preferably designed to engage with at least one ejector pin, in particular an automatic ejector. The ejector is, for example, part of a mold for manufacturing, in particular for casting a carrier or a casting. For example, pressure can be applied to a carrier in a casting mold for casting the carrier by means of an ejector pin (in particular directly) resting against the ejector boss, in order to press the carrier out of the casting mold. The ejector boss is therefore, for example, provided for ejecting the carrier from the casting mold. In other words, an "ejector boss" can be understood in particular as a seat for an ejector pin of an ejector. The ejector boss is preferably formed cylindrically. An "ejector pin" can be understood in particular as a seat that is pressed onto the ejector boss in order to separate the carrier from the casting mold. For example, the ejector boss, in particular the receiving opening, is at least partially formed or formed by the receiving pin when casting the carrier or the casting.

[0025] In general, it can be seen that the ejection boss can fulfill both the function of ejecting the carrier from the casting mold and the function of fixing the screw element in the receiving opening and thus the component on the carrier. As a result, the weight of the carrier can be kept particularly low.

[0026] In another embodiment, it is provided that the receiving opening is designed as a (especially unmachined) blind hole of the casting. In other words, the receiving opening is designed as a blind hole drilled hole, which is, for example, unmachined. Via the blind hole, the bolt element can be connected to the carrier in a particularly cost-effective manner. In addition, the receiving opening can be manufactured in a particularly cost-effective manner.

[0027] The term “receiving opening is unmachined or is designed as an unmachined blind hole” can be understood to mean, in particular, that no (in particular mechanical) machining takes place or is not necessary in the blind hole after the casting of the cast component. The blind hole is thus an unmachined region of the original casting or cast component (in particular the original casting). As a result, the manufacturing costs for producing the carrier or the blind hole can be kept particularly low.

[0028] In another embodiment, it is provided that the support element is designed as a longitudinal beam. In other words, the main extension direction of the support element, in particular in the installed position of the support element in the motor vehicle, extends at least substantially in the longitudinal direction of the vehicle. In particular, the rigidity of the motor vehicle body can be particularly increased by the support element. Alternatively, it is provided, for example, that the support element is designed as a node, in particular a cast node.

[0029] Preferably, it is provided that the support element is provided for the vehicle body or the rear end of the vehicle. This means that the support element is designed for the rear end, in particular for being arranged in the rear end. In other words, in particular in the fully manufactured state of the vehicle, the support element is arranged in the rear end of the vehicle or in the rear end structure. Thus, the longitudinal beam can be used in the rear end structure or in the rear end structure. In particular, the support element can be used to increase the rigidity of the rear end.

[0030] The second aspect of the invention relates to a method for producing a carrier for a vehicle body, in particular according to the first aspect of the invention. The advantages and advantageous configurations of the first aspect of the invention can be regarded as advantages and advantageous configurations of the second aspect of the invention, and vice versa.

[0031] The carrier is designed as a cast part and is formed at least in the longitudinal region of the carrier by at least one rib structure having a plurality of ribs which are connected to one another, in particular directly, at least in the region of at least one rib intersection.

[0032] In order to be able to keep the support particularly light, it is provided according to the invention that the rib intersections have receiving openings in which screw elements for fastening at least one component to the support are fastened.

[0033] Other features of the invention are apparent from the claims, the drawings and the description of the drawings. The features and feature combinations mentioned above in the description and the features and feature combinations mentioned below in the description of the drawings and / or shown individually in the drawings can be used not only in the respectively given combination but also in other combinations or individually.

[0042] In the figures, identical or functionally identical elements are provided with the same reference symbols.

[0043] Figure 1 A motor vehicle body 1 is shown in a schematic and perspective partial view. The motor vehicle body 1 has at least one carrier part 2 which is designed as a cast part 3 , in particular as an injection-molded part. Figure 2 The carrier 2 is shown in a schematic perspective partial view.

[0044] The carrier 2 is preferably made at least partially, in particular mostly or completely, from aluminum. Thus, the casting 3 is configured, for example, as an aluminum casting, in particular an aluminum die casting.

[0045] The carrier part 2 or the cast part 3 is reinforced at least in a length region 4 by at least one rib structure 5, which has a plurality of ribs 6. The ribs 6 are, at least in the region of at least one rib intersection 7, in particular directly connected to one another.

[0046] exist Figure 1In the embodiment shown, the rib structure 5 has a plurality of rib intersections 7. At least two ribs 6 are respectively (especially directly) connected to the respective rib intersections 7. The ribs 6 connected to each other, especially intersecting or crossing each other, at the respective rib intersections 7 extend, for example, obliquely or perpendicularly to each other.

[0047] In order to be able to keep the weight of the support 2 particularly low, it is provided that the respective rib intersections 7 each have at least one respective receiving opening 8, in which a respective screw element 9 is fixed or can be fixed for fixing at least one component (especially formed separately from the support 2) on the support 2. In other words, the respective screw element 9 is connected or can be connected to the support 2 (especially directly) via the respective receiving opening 8. This means that the component is connected or can be connected to the support 2 (especially directly) via the respective screw element 9. Therefore, the respective screw element 9 can be inserted into the respective rib intersection 7.

[0048] In another embodiment, it is provided that the carrier 2 has an open cross section 41 at least in the length region 4, and the outer wall 10 of the carrier 2 partially defines the receiving space 42 in the length region 4. In other words, the carrier 2, in particular the outer wall 10, has no continuous surface at least on one side. The rib structure 5 is preferably arranged inside the outer wall 10. For example, it is provided that at least the outer wall 10 of the carrier 2 is designed at least substantially U-shaped in the length region 4, and the rib structure 5 is arranged inside the outer wall 10. Therefore, the carrier 2 is preferably an open, in particular ribbed casting 3.

[0049] Figure 3 A corresponding screw element 9 is shown in a schematic side view. Figure 4 A corresponding screw element 9 is shown in a schematic front view. Figure 5 The arrangement of the corresponding screw elements 9 on the carrier 2 is shown in a schematic and perspective partial view. Figure 5 The screw element 9 mounted on the carrier 2 is shown in FIG.

[0050] It is preferably provided that the respective screw element 9 is fixed or secured in the receiving opening 8 by means of a respective thread 11, in particular a respective self-tapping thread 11. For example, the respective screw element 9 has a respective base body 12, on which the thread 11 is arranged. The thread 11 is preferably designed as an external thread. For example, by means of a respective self-tapping thread 11, a respective internal thread can be introduced, in particular cut into, in the respective receiving opening 8, in order to secure the respective screw element 9 by means of its thread 11.

[0051] The diameter 13 of the thread 11 corresponds, for example, to an M6 thread, in particular an M6GF thread. For example, the thread 11 has a first region 14 and a second region 15 at least indirectly, in particular directly adjoining the first region 14. The first region 14 is, for example, cylindrical. The second region 15 is, for example, provided for tapping. For example, the second region 15 is configured in a trilobal shape. The first region 14 has, for example, a length of 12 mm. The second region 15 has, for example, a length of 12 mm, and the second region 15 has, for example, a length of 8 mm. For example, the thread 11, in particular the second region 15, has at least one, in particular a maximum of four tapping threads 16.

[0052] For example, the respective screw element 9 has a first side 17 and a second side 18 which is different from the first side 17. The sides 17, 18 are preferably located opposite one another, in particular in the axial direction of the respective screw element 9. The thread 11 is preferably arranged on the first side 17. The first side 17 is therefore preferably the side 17 which faces the receiving opening 8. The first side 17 can be referred to in particular as the casting side.

[0053] The second side 18 is preferably the side 18 facing away from the receiving opening 8 or the carrier 2. For example, the corresponding screw element 9 has a second thread 19 on the second side 18 that is different from the thread 11 (especially referred to as the first thread 11), by which the component is (especially directly) fixed or can be fixed on the carrier 2. The second thread 19 is designed, for example, as an external thread. The second side 18 can be referred to, in particular, as the use side. Therefore, the component can be fixed on the use side.

[0054] In another embodiment, it is provided that the respective screw element 9 has a respective drive element 21 arranged between the first thread 11 and the second thread 19, via which the respective screw element 9 can be loaded with a torque for fixing the respective screw element 9 on the carrier 2. In other words, the respective screw element can be rotated by its drive element in order to tighten the respective screw element 9 with the carrier 2 (in particular in the receiving opening 8) via the first thread 11. Therefore, the drive element 21 is provided for mounting the screw element 9. The drive element 21 is, for example, configured as a hexagon, which has, for example, a corresponding side width of 13. For example, the drive element 21 is (in particular directly) arranged on the base body 12, in particular between the threads 11, 19.

[0055] For example, the thickness 22 of the corresponding drive element 21 of the corresponding bolt element 9 extending in the axial direction of the corresponding bolt element is 2.25 mm, in particular 2.25 mm ± 0.25 mm. For example, the corresponding thread 11 is spaced apart from the corresponding drive element 21 by a distance 23 in the axial direction of the corresponding bolt element 9. The distance 23 is, for example, 2.5 mm at most. For example, the corresponding second thread 19 is spaced apart from the corresponding drive element 21 by a second distance 24 in the axial direction of the bolt element 9. For example, the second distance is 2.5 mm at most. For example, the length 25 of the corresponding bolt element 9 extending from the corresponding drive element 21 in the axial direction of the corresponding bolt element 9 toward the carrier 2 is 20 mm, in particular 20 mm ± 0.42 mm. For example, the second length 26 extending from the corresponding drive element 21 in the axial direction of the corresponding bolt element 9 away from the carrier 2 is 20 mm, in particular 20 mm ± 0.5 mm.

[0056] For example, the corresponding screw element 9 is constructed in one piece. This means that the corresponding screw element 9 is formed from a single piece, for example a single block. For example, the first thread 11 and / or the second thread 19 and / or the drive element 21 and / or the base body 12 are constructed integrally together, that is, integrally with each other.

[0057] In another embodiment, it is provided that the respective rib intersection 7 has a respective boss 27 in which the respective receiving opening 8 is arranged, in particular at least partially. The respective boss 27 is preferably designed as an ejection boss. This means that (in particular due to the material accumulation) the respective ejection boss is introduced or introduced into the respective rib intersection 7. As a result, the respective receiving opening 8 or the respective screw element 9 can be arranged, in particular, in the respective rib intersection 7 in a particularly cost-effective manner.

[0058] It is preferably provided that the corresponding receiving opening 8 is designed as a (especially unmachined) blind hole 28 of the casting 3 or the carrier 2. This means that, in particular for a particular suitability for fastening components, the corresponding ejector boss can be adjusted or modified by the precast blind hole 28. It is preferably provided here that the function as an ejector boss is retained.

[0059] It is preferably provided that the support part 2 is designed as a longitudinal beam 29. It is preferably provided that the support part 2, in particular the longitudinal beam 29, is provided for a rear end 30 of the vehicle body 1. In other words, the support part 2 or the longitudinal beam 29 is designed as a rear longitudinal beam 29 of the vehicle body 1.

[0060] For example, the vehicle body 1, in particular the rear end 30, has a wheel house body in white, in particular a wheel house body in white component 31. The carrier 2 is, for example, arranged on the inside (in particular directly) on the wheel house body in white component 31. For example, the component is configured as a wheel house cover or as a wheel house shell, in particular a wheel house inner shell. For example, the carrier 2 is part of the wheel house body in white. Alternatively, the carrier 2 can be configured separately from the wheel house body in white. For example, the carrier 2 is connected (in particular directly) to the wheel house body in white component 31.

[0061] For example, the component is designed as an adapter plate. For example, the component is designed as a line element, in particular a cable harness, an electrical line, a line for data transmission, a brake line, a cooling line and / or an air line. For example, the line element is connected to the screw element 9 via at least one (in particular screwed) clip, in particular a plastic clip, which is connected to the screw element 9 (in particular via the second thread 19).

[0062] For example, at least one cross member is connected to the support 2 inwardly, in particular in the transverse direction of the vehicle (for example at least indirectly or directly). For example, the vehicle body 1 has at least one further support member which is spaced apart from the support 2 (in particular in the transverse direction of the vehicle). For example, the support 2 and the further support member are connected to each other via the at least one cross member, in particular via two cross members (for example at least indirectly or directly). For example, the support 2 and in particular the at least one cross member form a composite structure with at least one floor element and / or at least one luggage compartment floor. The floor element is designed, for example, as a floor, in particular as a main floor, or as a floor support.

[0063] For example, the motor vehicle body 1, in particular the rear end 30, has a rear wall 32 which, for example, has a central tunnel 33. Alternatively, the rear wall has no central tunnel 33, for example.

[0064] For example, the wheelhouse body in shell, in particular the wheelhouse body in shell component 31 and / or the carrier 2 are arranged (in particular at least indirectly or directly), for example, on the outside on the rear wall 32. For example, the carrier 2 has at least one connection area 34 for fastening a sill and / or a side wall. The sill or the side wall is, for example, part of the vehicle body 1.

[0065] Figure 6 The corresponding bolt element 9 is shown in a schematic partial section. Figure 6 The section AA is shown in FIG. Figure 3 The second thread 19 has, for example, a thread diameter 35 of 5 mm, in particular 5 mm ± 0.1 mm. For example, the base body 12 has, in the region of the second thread 19, a base body diameter 36 of, for example, 3.6 mm, in particular 3.6 mm ± 0.15 mm. For example, the pitch 37 of the second thread 19 is 1.6 mm.

[0066] Figure 7 Show Figure 6 Detail of section AA shown in B. Figure 7 The first angle 38 shown in FIG. 1 is, for example, 75 degrees. Figure 7 The second angle 39 shown in FIG. 1 is, for example, 75 degrees. Figure 7 The third angle 40 shown in FIG. 4 is, for example, 30 degrees.
