Description

Technical Field

[0001] The present invention relates to an assembly of a bottom component for an automobile body according to claim 1. Background Technology

[0002] DE102010055954A1 discloses a rear structure for a car body, comprising two longitudinal beams that are at least partially opposed to each other in the transverse direction of the vehicle and are configured as cast aluminum members, the longitudinal beams being interconnected by at least two crossbeams that are spaced apart from each other in the longitudinal direction of the vehicle and are configured as extruded aluminum profiles, wherein at least one bottom member configured as an aluminum plate is provided at least partially between the crossbeams. Summary of the Invention

[0003] The objective of this invention is to realize an assembly for the bottom components of an automobile body that enables the manufacture of different structural forms of the automobile body with particularly low cost and to particularly improve the mechanical load-bearing capacity of the automobile body.

[0004] The task described herein is solved by an assembly of a bottom component for an automobile body having the features of claim 1. Advantages of the invention are as described in the dependent claims and the specification.

[0005] The first aspect of the invention relates to an assembly of a bottom component for an automobile body. The automobile body can be understood, in particular, as a body for an automobile or a vehicle body. An automobile, for example, is configured as a passenger car or a commercial vehicle.

[0006] The vehicle body is preferably configured as a self-supporting body. The vehicle body, for example, at least partially defines the interior of the vehicle. The interior can be specifically referred to as the vehicle interior, and can be particularly understood as a passenger compartment or passenger cabin.

[0007] Preferably, the vehicle body, especially in a fully manufactured state, has the bottom assembly, and particularly the assembly. Preferably, the bottom assembly, especially in a fully manufactured state, has the assembly.

[0008] The underbody assembly can be understood, in particular, as the lower portion of the vehicle body (especially a self-supporting body) in the direction of vehicle height. The underbody assembly, for example, has connection points, specifically referred to as anchor points, for components of the vehicle's chassis and / or for the vehicle's drivetrain. The underbody assembly can be specifically referred to as a vehicle body underbody assembly. For example, the underbody assembly has at least one, particularly load-receiving, longitudinal or transverse structure, preferably multiple longitudinal and / or multiple transverse structures. "Longitudinal or transverse structure configured to receive loads" can be understood, in particular, as the longitudinal or transverse structure is configured to receive loads caused by an accident, such as a side collision and / or a frontal collision. The longitudinal or transverse structure, for example, can satisfy requirements in frontal, side, and / or rear-end collisions. For example, the underbody assembly, particularly the longitudinal and / or transverse structures, is at least partially, particularly primarily or entirely, made of metal, such as steel and / or aluminum.

[0009] The assembly has at least one first body component configured as a cast member. In other words, the first body component is manufactured by casting. The assembly also has at least one second body component configured as a cast member and constructed separately from, and particularly connected to, the first body component. In other words, the second body component is manufactured by casting.

[0010] The phrase "each body component is constructed separately from the others" can be understood in particular as meaning that each body component is not manufactured from a single piece. The body components are therefore manufactured independently of each other and connected to each other after their respective manufacturing. Consequently, the assembly, especially the bottom assembly, has a structure comprising more than one cast component, particularly separate cast components.

[0011] The corresponding body components are, for example, at least partially, especially mainly or entirely, made of aluminum. In other words, the corresponding body components are constructed as cast aluminum components. For example, the corresponding body components are manufactured by means of aluminum die casting.

[0012] To enable the manufacture of various automotive body structures with particularly low cost and to significantly improve the mechanical load-bearing capacity of the automotive body, a first body component is specified to have at least one receiving area, and a second body component is specified to have at least one receiving element corresponding to the receiving area. This receiving element is specifically at least partially, primarily, or completely received or disposed within the receiving area for form-locking connection of the various body components. In other words, the various body components are form-lockingly connected to each other, particularly directly form-lockingly connected, by receiving or disposed of the receiving element in the receiving area. This means that a form-locking connection is specified or constituted between the various body components. Again, in other words, at least one form-locking connection is formed between the various body components by the receiving element disposed in the receiving area.

[0013] In particular, the various body components are form-locked to each other in at least two spatial directions by receiving elements received in the receiving area. This means that the various body components are supported to each other, especially directly to each other, in at least two spatial directions by form-locked connection or form-locked connection. In other words, the first body component has at least one wall that at least partially, especially mainly or completely defines the receiving area, and the receiving elements received in the receiving area are supported to the wall in at least two spatial directions, especially directly to the wall.

[0014] The receiving area is configured, for example, as a recess and / or as an opening. The receiving element extends, for example, from the base of the second body component. For example, the receiving element is configured as a pin. Therefore, the form-locking connection, or form-locking connection, is configured, for example, as a form-locking pin connection. Thus, form-locking pin connections can be specified between body components, especially those referred to as cast components, particularly where the pin connection is configured by a receiving element and a receiving area.

[0015] This invention is particularly based on the following understanding and consideration: In principle, it is conceivable that assemblies, especially bottom components, can be constructed in a structural manner in which almost the entire rear structure and / or front structure of the vehicle, including the assembly or bottom component, is formed in a single part, i.e., integrally or as a single piece. However, in the development of vehicle architectures with different vehicle classes and different body styles, it is advantageous to employ a particularly large number of common and / or complementary components. Different vehicle classes are, for example, compact (UKL), small (KKL), mid-size (MKL), and large (GKL). Body styles are, for example, luxury cars, SUVs, convertibles, sedans, vans, or station wagons. Particularly large integrated cast components or cast structures can have the disadvantage that the specific requirements of each individual body structure may always involve compromises, for example, those arising from different vehicle classes and / or body styles. For example, particularly large integrated cast rear components may always have all possible receiving points or at least be prepared for this, and the cast rear structure should accommodate different seat structure classes through their respective specific threaded connections. This can lead to disadvantages in terms of cost, weight, and so on. Therefore, it is advantageous that different, smaller components, especially cast components, can be assembled into a modular system to allow for optimized body configurations depending on the vehicle type. Depending on the number of parts, their configuration within the body structure, factory footprint, and location, technological and ecological optimizations can, for example, be linked to complex business management considerations. Particularly high forces can act at the interface between two cast components, especially those extending separately from each other, which can typically withstand particularly high loads, especially in side or rear-end collisions. Due to the size of each cast component—for example, whether it extends across the entire width of the vehicle and / or across the entire rear or front length—particularly complex kinematics can be generated in a collision, in which the main loads should be received and transmitted in correspondingly different directions at the cast interface facing the impact and at the cast interface facing away from the impact.

[0016] In the assembly according to the invention, at least one of the cast components can be structurally specific. Because the cast components are constructed separately from each other, the manufacturing cost for different structural types used in manufacturing the automobile body can be kept particularly low. Furthermore, through form-locking connections, especially through elements received in receiving areas, particularly reliable connections, and particularly strong mechanically load-bearing connections, can be established between the various body components. Therefore, the mechanical load-bearing capacity of the assembly can be particularly improved. This means that the safety of the automobile or automobile body, particularly passive safety, and particularly safety in accident situations, can be particularly improved. For example, especially in the case of a side collision, load transfer in the lateral direction of the vehicle into the assembly, particularly at the interfaces between the various body components, such as through pin connections, especially through pin-groove connections, can be achieved in both tension and compression. Therefore, load transfer can be achieved particularly advantageously and particularly robustly. Overall, it is possible to realize a vehicle body having multiple body components that are form-locked together.

[0017] In another embodiment, the assembly is specified as a front or rear structure of the bottom component. In other words, the assembly is configured as the front or rear section of the bottom component, particularly as the front or rear section of a car body. This means that the assembly is configured as a front or rear structure of the bottom component, particularly as the front or rear structure of a car body. Therefore, the front or rear structure, especially for different structural types of car bodies, can be manufactured with particularly low cost and configured with particularly high mechanical load-bearing capacity. Especially because the front or rear structure is a fundamental component of the bottom component, the manufacturing cost of the bottom component, especially the manufacturing cost of the car body, can be particularly low, and the mechanical load-bearing capacity of the bottom component, especially the mechanical load-bearing capacity of the car body, can be particularly improved.

[0018] The front structure can be understood, in particular, as the area of ​​the underbody assembly, especially the vehicle body, in the forward direction of the vehicle's longitudinal direction. The rear structure can be understood, in particular, as the area of ​​the underbody assembly, especially the vehicle body, in the rear direction of the vehicle's longitudinal direction. The vehicle's longitudinal direction can be understood, in particular, as the longitudinal direction of the vehicle body and / or the vehicle's longitudinal direction.

[0019] In another embodiment, at least one of the body components, particularly in the case of the assembly's installation in the vehicle body or automobile, extends at least 70%, 80%, 90%, 95%, or 100% of the total width of the bottom component, particularly the vehicle body, extending in the lateral direction of the vehicle. In other words, at least one of the body components has a width in the lateral direction of the vehicle that is at least 70% of the total width of the bottom component, particularly the vehicle body. This means that the width of at least one of the body components, particularly the width of two body components, is at least 70% of the total width of the bottom component, particularly the vehicle body. Therefore, at least one of the body components constitutes a particularly large or particularly wide component in terms of its width. Thus, the particularly large body structures can be interlocked, thereby keeping the manufacturing cost of the body particularly low. Furthermore, each structural type can be manufactured with particularly low cost. The lateral direction of the vehicle can be particularly understood as the lateral direction of the vehicle body and / or the vehicle itself.

[0020] As an alternative or supplement, for example, it is stipulated that each body component extends collectively over at least 50%, particularly at least 60%, 70%, 80%, or 90% of the total length of the front or rear structure of the bottom assembly, which extends in the longitudinal direction of the vehicle, particularly in the case of the assembly's installation in the vehicle body or vehicle. In other words, each body component collectively, i.e., together or in total, is at least half the total length of the front or rear structure in the longitudinal direction of the vehicle. This means that the length of each body component extending in the longitudinal direction of the vehicle is at least 50%, particularly at least 60%, 70%, 80%, or 90% of the total length of the front or rear structure in total. The body components thus collectively constitute a particularly long structure of the assembly, particularly the bottom assembly. Therefore, particularly large body structures can be interlocked, thus keeping the manufacturing cost of the body particularly low. Furthermore, each structural type can be manufactured with particularly low cost.

[0021] Because the various body components are constructed in a particularly wide or particularly long manner, the assembly is therefore a fundamental component, especially the bottom assembly, and particularly the body of the automobile. Therefore, the advantages mentioned above regarding particularly low manufacturability and particularly large mechanical load-bearing capacity can be achieved to a particularly large or particularly important degree.

[0022] In another embodiment, at least one of the body components, particularly the first and / or second body components, is configured as a frame. This means that at least one of the body components is frame-shaped or constitutes a frame component. Through the frame structure, or through the frame structure of the bottom assembly, the mechanical load-bearing capacity of the vehicle body, especially its accident characteristics, can be significantly improved. In particular, a modular system with a frame can be realized, thus allowing for the manufacture of different structural forms with particularly low cost.

[0023] The frame is configured, for example, as a rear frame or a front frame, particularly as a bottom assembly or a rear or front frame of a vehicle body. The frame has, for example, two lateral elements, particularly spaced apart from each other in the longitudinal direction of the vehicle, and two longitudinal elements, particularly spaced apart from each other in the longitudinal direction of the vehicle. The respective main extension direction of the corresponding lateral elements preferably extends at least substantially in the transverse direction of the vehicle. The respective main extension direction of the corresponding longitudinal elements preferably extends at least substantially in the longitudinal direction of the vehicle. The respective lateral elements are configured, for example, as crossbeams. The respective longitudinal elements are configured, for example, as longitudinal beams.

[0024] The corresponding transverse elements can be understood, in particular, as the corresponding transverse structures. The corresponding longitudinal elements can be understood, in particular, as the corresponding longitudinal structures.

[0025] Preferably, the first body component and the second body component are constructed as single pieces, especially as separate single pieces. This means that the first body component is constructed from a single object, especially from a single unit. Alternatively or supplementarily, the second body component is constructed from a single object, especially from a single unit. The first body component therefore, for example, does not include structural elements that are constructed separately from each other and, especially, subsequently interconnected. Alternatively or supplementarily, the second body component does not include structural elements that are constructed separately from each other and, especially, subsequently interconnected.

[0026] In another embodiment, the receiving element, which is received or disposed in the receiving area, is supported, preferably directly supported, on the wall of the first body member that at least partially defines the receiving area, at least substantially in the vehicle's lateral direction and at least substantially in the vehicle's height direction (and especially at least substantially in the vehicle's longitudinal direction). This means that the body members are supported to each other by the wall and the receiving element at least substantially in the vehicle's lateral direction and in the vehicle's height direction (and especially in the vehicle's longitudinal direction). In other words, the body members are shaped-locked together in at least two spatial directions, especially in three spatial directions, such as in the vehicle's lateral direction, in the vehicle's height direction, and especially in the vehicle's longitudinal direction. Therefore, a particularly reliable mechanical connection can be achieved between the body members, thus significantly improving the mechanical load-bearing capacity of the vehicle body.

[0027] In another embodiment, the receiving opening and the receiving element are specified to each have a corresponding U-shaped cross-section. This means that the receiving opening has a first cross-section that is U-shaped, and the receiving element has a second cross-section that is U-shaped. In other words, the receiving opening and the receiving element are respectively at least partially, especially mainly or completely, U-shaped, particularly as U-shaped profiles. Therefore, particularly reliable form-locking connections can be achieved between the various body components. In addition, the various body components, especially the form-locking connections, can be manufactured with particularly low cost.

[0028] In another aspect of the invention, it is specified that, in particular, in addition to form-locking connections, the various body components are threaded and / or bonded to each other. In other words, the various body components are connected to each other, especially directly, by means of bolts (i.e., by at least one threaded connection) and / or by means of bonding. Therefore, with respect to form-locking connections, a particularly reliable, especially mechanically load-bearing, additional connection can be achieved between the various body components. In particular, the safety of preventing the form-locking connection from loosening can be significantly improved. Therefore, the mechanical load-bearing capacity of the automobile body, especially the mechanical load-bearing capacity of the underbody components, can be particularly improved.

[0029] In another embodiment, the receiving element is specified to be threadedly connected and / or bonded, particularly directly threaded and / or bonded, to the wall of the first body component that at least partially defines the receiving area. This means that the threaded connection and / or bonding of the various body components is achieved by means of the receiving element and the wall that at least partially defines the receiving area. In other words, the receiving element has at least one connection area through which the receiving element received in the receiving area is threadedly connected and / or bonded, particularly directly threaded and / or bonded, to the wall of the first body component that at least partially defines the receiving area. Therefore, the safety of preventing the form-locking connection from loosening, i.e., the safety of preventing the receiving element from being undesirably removed from the receiving area, can be particularly improved. Therefore, the mechanical load-bearing capacity of the bottom assembly or the mechanical load-bearing capacity of the vehicle body can be particularly improved.

[0030] In another embodiment, at least one of the body components, particularly the first and / or second body components, has at least one rib structure, which has multiple ribs. This means that the rib structure has multiple ribs that extend, for example, obliquely or perpendicularly to each other and / or intersect each other. The rib structure can be understood, in particular, as a reinforcing or strengthening structure having multiple ribs. In other words, at least one of the body components is reinforced or strengthened, particularly locally, by the rib structure. The rib structure can particularly improve the stiffness of the first or second body component. Therefore, the mechanical load-bearing capacity of the assembly or the bottom component can be particularly improved. In particular, stiffness or mechanical load-bearing capacity can be improved in a way that is particularly advantageous in terms of weight. Therefore, the weight of the assembly can be kept particularly low.

[0031] In another embodiment, the first body component has at least one second receiving area, particularly in the vehicle's lateral direction and / or longitudinal direction, spaced apart from the receiving area, and the second body component has at least one second receiving element, particularly in the vehicle's lateral direction, spaced apart from the receiving element and corresponding to the second receiving area. The second receiving element is received within the second receiving element for form-locking connection of the body components, particularly for direct terrain-locking connection, and is received at least partially, primarily, or completely within the second receiving element. In other words, the body components are form-lockingly connected to each other, particularly for direct terrain-locking connection, by receiving or providing the second receiving element in the second receiving area. This means that at least one second form-locking connection, different from the form-locking connection, is provided or constituted between the body components. Again, in other words, at least one second form-locking connection is formed between the body components by the second receiving element provided in the second receiving area.

[0032] In particular, the various body components are interconnected in a form-locking manner in at least two spatial directions by means of a second receiving element received in the second receiving area. This means that the various body components support each other, especially directly, in at least two spatial directions by means of the second form-locking connection. In other words, the first body component has at least one second wall that at least partially, especially mainly or completely defines the first receiving area, and the second receiving element received in the second receiving area is supported on the second wall in at least two spatial directions, especially directly, on the second wall.

[0033] The second receiving area is configured, for example, as a recess and / or an opening. The second receiving element extends, for example, from the base of the second body component. For example, the second receiving element is configured as a pin. Therefore, the form-locking connection, or the second form-locking connection, is configured, for example, as a form-locking pin connection. Thus, a form-locking pin connection can be specified between body components, especially those referred to as cast components, particularly through the second receiving element and the second receiving area.

[0034] Each receiving element is constructed identically, for example. Each receiving area is constructed identically, for example.

[0035] Preferably, the receiving element received in the receiving area and the second receiving element received in the second receiving area are arranged on different sides of the bottom assembly, especially opposite sides, in the vehicle lateral direction (with respect to the vehicle lateral direction), especially on different sides of the vehicle body, especially on opposite sides. This means that the receiving area, especially the receiving element, which can be called the first receiving area, and the receiving element, especially the receiving element, are arranged on a first side of the bottom assembly, especially on a first side of the vehicle body, in the vehicle lateral direction or with respect to the vehicle lateral direction, and the second receiving area and the second receiving element are arranged on a second side of the bottom assembly, different from the first side, especially opposite to the first side, in the vehicle lateral direction or with respect to the vehicle lateral direction, especially on a second side of the vehicle body, different from the first side, especially opposite to the first side. In other words, the body components are form-locked to each other on both sides with respect to the vehicle lateral direction, especially through the receiving areas and receiving elements. Therefore, the body components can be connected to each other particularly reliably. In particular, the mechanical load-bearing capacity of the assembly, especially the mechanical load-bearing capacity of the bottom assembly, can be particularly improved.

[0036] For example, the spacing between the receiving elements extending in the vehicle lateral direction is at least 50%, especially at least 60%, 70% or 80% of the total width of the first body component and / or the second body component, especially the assembly, such as the bottom component or the car body, extending in the vehicle lateral direction.

[0037] Another aspect relates to a bottom assembly for an automobile body, said bottom assembly comprising at least one assembly according to the invention. The advantages and benefits of said other aspect can be considered as advantages and benefits of the present invention, and vice versa. An automobile body is also disclosed, said automobile body comprising a bottom assembly having at least one assembly according to the invention.

Features and combinations of features mentioned above in the specification, as well as features and combinations of features mentioned below in the description taken in conjunction with the drawings and / or shown separately in the drawings, may be applied not only in the correspondingly described combinations, but also in other combinations, or may be applied separately.

[0051] In the accompanying drawings, identical or functionally equivalent elements are given the same reference numerals. Detailed Implementation

[0052] Figure 1 An assembly 1 of a bottom component 2 for a car body 3 is shown in a schematic and perspective partial sectional view. Figure 2 The schematic top view shows assembly 1, especially the bottom component 2 or the car body 3.

[0053] The assembly 1 has at least one first body component 5 configured as a cast component 4, particularly as an aluminum die-cast component. Additionally, the assembly 1 has at least one second body component 6 configured as a cast component 4 and separately configured from the first body component 5.

[0054] In this embodiment, the assembly 1 is configured as the rear structure 7 of the bottom component 2, and more particularly as the rear structure of the vehicle body 3. In other words, the rear structure 7 is at least partially, and more particularly mainly or entirely, constituted by the body components 5 and 6. The body components 5 and 6 are therefore provided or can be provided in the rear of the vehicle having the vehicle body 3. Alternatively, the assembly 1 may be configured as the front structure of the bottom component 2, and more particularly as the front structure of the vehicle body 3.

[0055] As in Figure 2As shown, assembly 1 has, for example, at least one third body component 8, particularly said third body component being separately constructed from body components 5 and 6, and said third body component is preferably a component of bottom assembly 2, particularly a component of automobile body 3. The third body component 8 is, for example, a single component, particularly a one-piece component, which can be referred to as a single component; or the third body component 8 is, for example, a component complex having multiple components, particularly multiple components separately constructed from each other. The third body component 8 is, for example, constructed as a cast component 4, particularly as an aluminum die-cast component. For example, the rear end 10 of bottom assembly 2 about the longitudinal direction of the vehicle 9 is at least partially, particularly mainly, or completely formed by the third body component 8. Alternatively or supplementarily, the third body component 8 has, for example, at least one bottom element 8a, particularly referred to as a bottom, which is, for example, constructed as a bottom plate. Alternatively or supplementarily, two wheel covers are spaced apart from each other, particularly in the lateral direction of the vehicle 11, and these two wheel covers are at least partially, particularly mainly, or completely formed or defined by the third body component 8. The corresponding wheel covers 12 are preferably constructed or provided for receiving the corresponding wheels.

[0056] Body components 5 and 6 are connected, for example, to a third body component 8, particularly directly. For instance, the first body component 5 extends between two side beams 13 of the bottom assembly 2, particularly between two side beams 13 of the vehicle body 3, especially since the side beams are spaced apart from each other in the lateral direction of the vehicle. For example, the second body component 6 extends between wheel covers 12, particularly in the lateral direction 11 of the vehicle, the wheel covers being configured, for example, as wheel cover shells.

[0057] Figure 3 and Figure 4 Assembly 1 is shown in the respective schematic partial sectional views. To enable the manufacture of different structural forms of the vehicle body 3, particularly different structural forms of the bottom component 2, with particularly low cost, and to particularly improve the mechanical load-bearing capacity of assembly 1, particularly the mechanical load-bearing capacity of the bottom component 2 or the vehicle body 3, it is specified that: the first body component 5 has at least one receiving area 14 and the second body component 6 has at least one receiving element 15 corresponding to the receiving area, which is received or disposed in the receiving area 14 for form-locking connection of the various body components 5, 6. This means that at least one form-locking connection 17 is specified, which is formed by the receiving element 15 and the receiving area 14, particularly by a wall 16 of the first body component 5 that at least partially, for example mainly or completely defines the receiving area 14, and the various body components 5, 6 are interconnected, particularly directly interconnected, by the at least one form-locking connection.

[0058] Instead of the single-piece integrated assembly 1, the various body components 5 and 6 can therefore be constructed separately from each other. Thus, each body component 5 and 6 can be structurally specific, enabling the manufacture of different structural forms of the bottom assembly 2, and especially different structural forms of the automobile body 3, with particularly low cost. Here, the various body components 5 and 6 can be connected to each other particularly reliably via form-locking connections 17, and particularly mechanically and load-bearingly.

[0059] exist Figure 2 The diagram also includes a schematic first partial view A and a schematic second partial view B of the assembly 1. In the embodiment, the first body component 5 has at least one second receiving region 18 spaced apart from the receiving region 14, and the second body component 6 has at least one second receiving element 19 spaced apart from the receiving element 15 and corresponding to the second receiving region 18. The receiving region 14 may be referred to in particular as the first receiving region 14, and the receiving element 15 may be referred to in particular as the first receiving element 15. The second receiving element 19 is received or disposed in order to form a locking connection between the body components 5, 6. This means that the body components 5, 6 are interconnected, in particular directly interconnected, by at least one second locking connection 21, which is formed, in particular, by the second receiving element 19 and the second receiving region 18, for example, by at least one wall 20 that at least partially, primarily, or completely defines the second receiving region 18. The locking connections 17, 21 are structurally identical, for example. The locking connection 17 may be referred to in particular as the first locking connection.

[0060] Preferably, the receiving element 15 received in the first receiving area 14 and the second receiving element 19 received in the second receiving area 18 are disposed on opposite sides 22, 23 in the vehicle lateral direction 11. This means that the first shaped locking connection 17 is disposed on the first side 22, and the second shaped locking connection 21 is disposed on the second side 23, which is different from the first side 22 in the vehicle lateral direction 11, and particularly opposite to the first side 22 in the vehicle lateral direction 11. The first side 22 is, for example, the left side of the bottom assembly 2, and particularly the left side of the vehicle body 3, and the second side 23 is, for example, the right side of the bottom assembly 2, and particularly the right side of the vehicle body 3.

[0061] exist Figure 2 The description refers to the load introduction 24 during a side impact, specifically a collision. In this case, the force caused by the accident is introduced into the side beam 13 and transmitted to the assembly 1, particularly to the first body member 5, or further into the assembly 1, particularly further into the first body member 5. Figure 2In the example described, the first locking connection 17 is on the side facing the impact, and the second locking connection 21 is on the side away from the impact. The force flow applied to the assembly 1 due to the side impact... Figure 2 This is indicated by arrow 25. At the corresponding shaped-locking connections 17, 21, the force caused by the accident due to a side impact is at least partially transmitted from the first body member 5 to the second body member 6. In other words, at the corresponding shaped-locking connections 17, 21, the second body member 6 is loaded, in particular mechanically, by the first body member 5 due to a side impact. As described in the first detail A, a mechanical load acts inward in the vehicle lateral direction 11 and rearward in the vehicle longitudinal direction 9, particularly on the first shaped-locking connection 17, which is specifically called the first interface. This mechanical load acts particularly between the body members 5, 6. Therefore, a pressure load acts on the first interface, which acts particularly on the second body member 6. As described in the second detail B, a mechanical load acts outward in the vehicle lateral direction 11 and forward and rearward in the vehicle longitudinal direction 9, particularly on the second shaped-locking connection 21, which is specifically called the second interface. This mechanical load acts particularly between the body members 5, 6. This is described in each detail A, B by arrow 27. Especially in the event of a side collision, the load transfer between the various body components 5 and 6, particularly from the first body component 5 to the second body component 6, can exert pressure and tension in the lateral direction 11 of the vehicle. This load transfer can be achieved particularly reliably through the corresponding form-locking connections 17 and 21, especially preventing the separation of the various body components 5 and 6, and especially preventing the separation of the corresponding form-locking connections 17 and 21. This is particularly advantageous when the corresponding form-locking connections 17 and 21 are configured as corresponding pin-slot connections. In other words, the corresponding receiving areas 14 and 18 are configured as slots, for example, and the corresponding receiving elements 15 and 19 are configured as pins, or in other words, as pin-shaped.

[0062] exist Figure 5 Sectional detail B is shown exemplarily in the schematic partial sectional view.

[0063] Each body component 5, 6 is preferably configured as a particularly large body component 5, 6. This means that the assembly 1 is constructed in a structural manner with particularly large cast components 4. Each body component 5, 6 integrates, for example, different vehicle functions, such as longitudinal structures, transverse structures and / or load-bearing parts or the like.

[0064] For example, at least one of the body components 5 and 6 extends at least 70%, especially at least 80%, 90%, 95%, or 100% of the total width 28 of the bottom assembly 2, especially the vehicle body 3, extending in the vehicle's lateral direction 11. For example, both body components 5 and 6 extend at least 70%, especially at least 80%, 90%, 95%, or 100% of the total width 28 of the bottom assembly 2, especially the vehicle body 3, extending in the vehicle's lateral direction 11. Alternatively or supplemented, each body component 5 and 6, for example, jointly extends at least 50%, especially at least 60%, 70%, 80%, or 90% of the total length 29 of the front or rear structure 7 of the bottom assembly 2 extending in the vehicle's longitudinal direction 9, and especially jointly extends at least 50%, especially at least 60%, 70%, 80%, or 90% of the total length of the front or rear structure of the vehicle body 3 extending in the vehicle's longitudinal direction.

[0065] In another embodiment, at least one of the body components 5 and 6 is specified as constituting a frame 30. (As shown in...) Figures 1 to 5 In the corresponding embodiments, the first and second body components 5 and 6 are configured as a frame 30, or in other words, as a frame shape, particularly as frames or as frame shapes respectively. In particular, the rear frame of the bottom component 2 is at least partially, particularly mainly or completely formed by the first or second body components 5 and 6.

[0066] In display Figures 1 to 5 In a corresponding embodiment, the first body component 5 has two longitudinal elements 31 and two transverse elements 32. Each transverse element 32 of the first body component 5 is preferably constructed as a single piece. Additionally, the second body component 6 has two longitudinal elements 33 and two transverse elements 34. Each longitudinal element 33 and each transverse element 34 of the second body component 6 is preferably constructed as a single piece. The transverse elements 32 of the first body component 5 that are rearward in the vehicle's longitudinal direction 9 are configured, for example, as a rear heel plate, particularly as the rearward region of the rear heel plate in the vehicle's longitudinal direction 9. The corresponding longitudinal elements 31 and 33 can be referred to as longitudinal beams, and the corresponding transverse elements 32 and 34 can be referred to as transverse beams.

[0067] Figure 6 The schematic perspective view shows an assembly 1 according to another embodiment, in which the first body component 5 is configured as a frame 30 and the second body component 6 has only one transverse element 34. This means that, as shown in the... Figure 6In the embodiment shown, the locking connections 17 and 21 are not directly connected to each other via the second body member 6 in the lateral direction 11 of the vehicle, but are connected to each other via the first body member 5, specifically regarding the body members 5 and 6 being connected to each other only via the first body member 5. In contrast, in the embodiment shown... Figures 1 to 5 In the corresponding embodiments, the various locking connections 17 and 21 are interconnected, especially directly interconnected, through the first and second body components 5 and 6. Figure 7 The detailed drawing illustrating the first-form locking connection 17 shows the button pressed against... Figure 6 Assembly 1 of the embodiment shown in the figure.

[0068] For example, the first and / or second body components 5, 6 have at least one connection point, particularly a separate connection point, through which the first or second body component 5, 6 is connected to or is connectable to an axle bracket, particularly a rear axle bracket. For example, the first body component 5, particularly one of the lateral elements 32 in the longitudinal direction 9 of the vehicle, has at least one seat receiving portion 35 for securing at least one seat device. The seat device can be understood, in particular, as a vehicle seat. For example, at least one of the body components 5, 6, such as the second body component 6, has at least one connection point for securing at least one spring element and / or damping element of the vehicle's wheel suspension.

[0069] Preferably, the respective receiving elements 15 and 19 received in the respective receiving areas 14 and 18 are supported or can be supported on the respective walls 16 and 20 that at least partially define the respective receiving areas 14 and 18, at least in the vehicle lateral direction 11 and in the vehicle height direction 36. In particular, the respective receiving elements 15 and 19 received in the respective receiving areas 14 and 18 are supported or can be supported at least inward and outward in the vehicle lateral direction 11 and downward and upward in the vehicle height direction 36.

[0070] For example, it is specified that the corresponding receiving areas 14 and 18 are configured as corresponding recesses and / or corresponding receiving openings, and the corresponding receiving areas and corresponding receiving elements 15 and 19 each have a corresponding U-shaped cross-section 37. In other words, the corresponding receiving areas 14 and 18 and the corresponding receiving elements 15 and 19 each have a corresponding U-shaped profile. (The last sentence appears to be incomplete and possibly refers to a different document.) Figures 1 to 7 In the corresponding embodiments, the corresponding U-shaped cross section 37 or the corresponding U-shaped profile is formed to be open upward in the vehicle height direction 36, and in particular, to be closed downward in the vehicle height direction 36.

[0071] Figure 8The schematic and perspective partial view shows the first and second body components 5, 6 according to another embodiment, in which the corresponding U-shaped cross section 37 or the corresponding U-shaped profile is formed to be open downward in the vehicle height direction 36, and in particular to be closed upward in the vehicle height direction 36.

[0072] Figure 9 An assembly 1 according to another embodiment is shown in a schematic and perspective partial view, in which the corresponding U-shaped cross section 37 or the corresponding U-shaped profile is formed to be open downward in the vehicle height direction 36, and in particular to be closed upward in the vehicle height direction 36.

[0073] In addition, Figure 8 In the middle, the various body components 5 and 6 are not yet connected to each other. Therefore, in Figure 8 The description specifically refers to a joining process, often called engagement, for engaging corresponding receiving elements 15, 19, for example, configured as pins, in corresponding receiving areas 14, 18, for example, configured as grooves. This is in Figure 8 The direction of engagement is described by arrow 38, which, for example, describes the direction of engagement.

[0074] In another embodiment, the various body components 5, 6 are specified to be threaded and / or bonded to each other. Preferably, the corresponding receiving elements 15, 19 are threaded and / or bonded to the corresponding walls 16, 20 of the first body component 5 that at least partially define the corresponding receiving areas 14, 18. Thus, at least one form-locking pin connection is provided between the various body components 5, 6, which may optionally be provided with additional threaded connection devices.

[0075] As exemplarily in Figure 4 As described, the respective receiving elements 15, 19 respectively have at least one corresponding receiving member 39 configured as, for example, a socket or hole, in which at least one threaded element 40 configured as, for example, a bolt is received or can be received, particularly for threaded connection of the respective receiving elements 15, 19 to the respective walls 16, 20. For example, multiple such receiving members 39 are specified. For example, the respective receiving members 39, particularly in the vehicle height direction 36, extend, for example, upwards, from the base surface 41 of the respective receiving elements 15, 19.

[0076] For example, the various body components 5, 6 are threadedly connected to each other by at least one additional threaded element 42 spaced apart from the corresponding receiving elements 15, 19 and / or the corresponding receiving regions 14, 18. This is exemplarily shown in Figure 4 As described in the text.

[0077] As exemplarily in Figure 4As described, the corresponding receiving elements 15, 19 and the corresponding walls 16, 20 are bonded to each other, for example, by means of an adhesive, on the other hand, by means of at least one corresponding surface 43 pointing inward and outward in the lateral direction 11 of the vehicle.

[0078] For example, the corresponding receiving elements 15, 19 and the corresponding walls 16, 20 are interconnected by at least one bolt connection 44, and in particular, multiple bolt connections 44. This exemplarily demonstrates... Figure 4 As described in the text. For this purpose, the corresponding receiving elements 15, 19, for example, have at least one corresponding second receiving member 45, in which at least one corresponding bolt is received or can be received, particularly for realizing the corresponding bolt connection 44. For example, multiple such receiving members 45 are specified. The corresponding receiving members 45 are configured, for example, as corresponding sockets. For example, the corresponding second receiving member 45 extends, particularly inwardly, from the corresponding sidewall of the corresponding receiving element 15, 19 in the vehicle lateral direction 11. Instead of the bolt connection 44 or attached to the bolt connection, a threaded connection may also be specified.

[0079] For example, the corresponding receiving elements 15, 19 are supported, particularly forward, and directly supported on the corresponding walls 16, 20 of the first body member 5 in the longitudinal direction 9 of the vehicle. Alternatively or supplementarily, the corresponding receiving elements 15, 19 are supported, particularly forward, on the corresponding walls 16, 20 of the first body member 5 in the longitudinal direction 9 of the vehicle. Therefore, load transfer between body members 5, 6 in the longitudinal direction 9 of the vehicle, particularly forward and / or rearward, for example, in both longitudinal directions, can be achieved by the corresponding threaded elements 40, i.e., by the corresponding threaded connection or threaded connection and / or by the corresponding bolt connection 44, particularly called a locking device. This is exemplarily demonstrated in… Figure 4 As described in the text.

[0080] For example, it is specified that at least one of the body components 5 and 6, especially the first and / or second body components 5 and 6, constitutes a longitudinal beam 46. Figure 10 The schematic perspective view shows an assembly 1 according to another embodiment, in which the first body component 5 is configured as a frame 30 and the second body component 6 is configured as a longitudinal beam 46, the second body component being connected to the first body component 5 in particular by a first locking connection 17.

[0081] Figure 11 The partial sectional view, in schematic and perspective, shows the pressing on Figure 10 Assembly 1, as described in the embodiment, is used to describe the first locking connection 17. The first receiving element 15 and the wall 16 are preferably connected to each other by means of at least one threaded element 47 and / or by means of a bolt connection 44.

[0082] As in Figure 10 As shown, assembly 1 has, for example, at least one fourth body component 48, which is separately constructed from the first and second body components 5 and 6 and, in particular, from the third body component 8. This fourth body component 48 is preferably constructed as a cast component 4, particularly an aluminum die-cast component. The fourth body component 48 is interconnected, for example, by means of a second locking connection 21, particularly directly interconnected. The fourth body component 48 is preferably constructed as a longitudinal beam 46.

[0083] For example, it is specified that at least one of the body components 5, 6, and 48 has at least one rib structure 49, and the rib structure has a plurality of ribs 50.

[0084] Ordinal numbers, such as "first," "second," "third," etc., are used primarily for distinction and, more importantly, do not indicate order. That is to say, corresponding ordinal numbers can be arbitrarily interchanged.
