[0005] Furthermore, DE 10 2016 010 542 A1 discloses a structure of a suspension dome section for a motor vehicle.

[0006] Furthermore, a strut tower is known from DE 10 2014 104 838 A1.

[0007] The object of the invention is to create a spring support element for a motor vehicle, a spring support for a motor vehicle and a motor vehicle, so that the weight of the motor vehicle can be kept particularly low.

[0008] This problem is solved according to the invention by a spring support element for a motor vehicle with the features of claim 1, by a spring support for a motor vehicle with the features of claim 6, and by a motor vehicle with the features of claim 8. Advantageous embodiments of the invention are the subject of the dependent claims and the description.

[0009] A first aspect of the invention relates to a spring support element for a motor vehicle, preferably for the body of the motor vehicle, and in particular for a spring support. The term "body" refers in particular to a body shell, which can be described as the superstructure. The body is preferably designed as a self-supporting body. Preferably, the motor vehicle, particularly in its fully manufactured state, comprises the body, the spring support element, and / or the spring support. For example, the spring support, particularly in its fully manufactured state, comprises the spring support element.

[0010] The term "spring support," which can also be called a strut support, refers specifically to a strut tower. Similarly, the term "spring support element," which can also be called a strut support element, refers specifically to a strut tower element.

[0011] The spring support element has at least one mounting area through which a spring and / or damper assembly, designed to couple a vehicle wheel to the spring support element, can be connected to the spring support element, particularly at least indirectly or directly, for example, via at least one support bearing. In other words, the spring and / or damper assembly can be attached to the spring support element via the mounting area, for example, via the support bearing. Preferably, by connecting or attaching the spring and / or damper assembly to the spring support element, the vehicle wheel can be coupled to the vehicle body via the spring and / or damper assembly, in particular by means of suspension and / or damping. This coupling is understood to mean, in particular, a mechanical coupling.In other words, the spring support element, in particular the body, is preferably supported or supported on a surface, such as a roadway, via the vehicle wheel, in particular by means of a spring and / or damping device. Accordingly, the vehicle wheel is understood to be, in particular, a ground contact element of the motor vehicle. Preferably, the vehicle wheel rolls on or against the surface while the motor vehicle is in motion. The spring and / or damping device is, for example, designed as a shock absorber.

[0012] The spring support element is designed as a sheet metal component. In other words, the spring support element is constructed of sheet metal. Thus, the spring support element is, for example, at least partially, and in particular at least predominantly or completely, made of sheet metal. "Sheet metal" specifically refers to metallic sheet metal.

[0013] To minimize the weight of the motor vehicle, particularly the spring support element, the invention provides that the spring support element has at least one wall section extending radially along the spring support element, at least between the mounting area and a central axis of the spring support element, which is parallel to an axial direction. In other words, the wall section is arranged radially along the spring support element at least between the mounting area and the central axis, which extends parallel to the axial direction of the spring support element. The term "wall section" refers in particular to a wall of the spring support element or a part thereof, wherein this wall is, for example, a component of a base body of the spring support element.The wall section is formed at least as part of a spherical surface, particularly an imaginary one. This means that the wall section is shaped at least as part of the spherical surface. In other words, the wall section is formed or shaped, at least in certain areas, particularly in the radial direction between the fastening area and the central axis, as a spherical layer, a spherical segment, and / or a spherical cutout. This means, in particular, that the wall section is formed or shaped at least as part of a spherical layer, a spherical segment, or a spherical cutout. Thus, the wall section, for example, has a spherical layer shape, a spherical segment shape, and / or a spherical cutout shape.

[0014] The spherical layer can be described as a spherical disk. In particular, the term "spherical layer" refers to a portion of a sphere that is cut out, or is cut out, by two parallel, and especially spaced-apart, planes. A curved portion of this cutout can be described as a spherical zone.

[0015] A spherical segment can be described as a section of a sphere. Specifically, a spherical segment is understood to be a part of a sphere that is separated by a cut with a plane, particularly the sphere itself. In particular, the spherical segment has a dome shape and, for example, a circular disk as its base. For instance, a spherical segment is a special case of a spherical layer, where the height of the spherical segment extends to the surface of the sphere. A spherical sector can be described as a sector. Specifically, a spherical sector is understood to be a cone-shaped section of a sphere extending to its surface.

[0016] The term "sphere surface" refers in particular to a surface, or at least a part of the surface, of a sphere, especially an imaginary one, which can be described as a spherical body. The term "sphere surface" also refers in particular to a dome surface, that is, in particular, a surface of a dome, especially an imaginary one.

[0017] The characteristics "spherical layer-shaped", "spherical segment-shaped" and "spherical cut-out-shaped" do not necessarily require that the wall section extends completely around the central axis, i.e. in particular by 360 degrees, but in particular a partial circumnavigation of the central axis by the wall section is possible, such as by at least 90 degrees or by at least 180 degrees.

[0018] The invention is based in particular on the following findings and considerations: For spring support elements or spring supports, the use of aluminum die-casting or sheet metal construction, especially sheet metal shell construction, with high wall thicknesses is conceivable in principle. The use of aluminum die-casting can negatively impact the manufacturing effort, and in particular the manufacturing costs, of the spring support element or spring support, since aluminum die-casting can typically be very expensive. The high wall thicknesses of the sheet metal shell construction can typically have a negative impact on the weight of the vehicle. Weight, in this context, refers in particular to the mass of the vehicle.In order to keep the weight of the motor vehicle as low as possible, it is particularly advantageous to be able to ensure stiffness requirements when connecting the spring and / or damper device while simultaneously keeping the component weight of the spring support element as low as possible.

[0019] In contrast, the aforementioned disadvantages can be avoided by means of the spring support element according to the invention. Because the spring support element according to the invention is designed as a sheet metal component, the manufacturing effort, and in particular the manufacturing costs, of the spring support element can be kept particularly low, thereby also keeping the manufacturing effort, and in particular the manufacturing costs, of the motor vehicle particularly low. Furthermore, because the wall section of the spring support element according to the invention is designed at least as part of the spherical surface or in a spherical layer, spherical segment, and / or spherical cutout shape, the stiffness of the spring support element can be increased, particularly in a weight-efficient manner.This means that, in the spring support element according to the invention, the desired stiffness requirements can be achieved in particular through optimized design, especially in a dome shape, preferably with a small or particularly small wall thickness, at least of the wall section of the spring support element. Thus, the connection of the support bearing to the spring support element can be designed to be particularly stiff with the smallest possible wall thickness and / or the smallest possible weight of the spring support element.

[0020] To minimize the weight of the vehicle, and especially the spring support element, the mounting area is designed as a recess in the wall section, particularly when the spring support element is installed in the vehicle, extending downwards in the vehicle's vertical direction. In other words, the mounting area projects downwards, and in particular directly, from the wall section in the vehicle's vertical direction. This allows the wall section, at least in areas spaced away from the mounting area, to be shaped as part of the spherical surface, or as a spherical layer, spherical segment, and / or spherical cutout. Furthermore, the recess can stiffen the wall section. This means that the recess can significantly increase the stiffness of the spring support element, and especially of the wall section.

[0021] Furthermore, it is stipulated that the recess is an embossed feature. In other words, the recess is designed as an embossed feature. In other words, it is stipulated that the mounting area or the recess is produced by means of embossing or embossing. An embossed feature is understood to be, in particular, a bead. Through the embossing, especially in the form of a stiffening bead, the stiffness of the spring support element, especially of the wall section, can be significantly increased. This allows the wall thickness of the spring support element, especially of the wall section, to be kept particularly thin. The embossing is, for example, a particularly pronounced local embossing at the mounting area, also referred to as the mounting point.Thus, the desired stiffness requirements can be achieved, for example, through optimized shape design in the form of stiffening ribs or embossings, while simultaneously using a particularly thin wall.

[0022] To minimize the weight of the vehicle, particularly the spring support element, a further embodiment provides that the mounting area is designed as a contact surface for the support bearing, via which the spring and / or damper assembly can be connected to, or is connected to, the spring support element. In other words, the connection or fastening of the spring and / or damper assembly via the mounting area is achieved through the support bearing, which extends between the mounting area and the spring and / or damper assembly. This means that the support bearing rests directly against the contact surface. Thus, the mounting area is designed, for example, as a support bearing connection point.Particularly when the mounting area is designed as a contact surface and as the aforementioned recess, the mounting area can provide a particularly small contact area for the support bearing, so that the support bearing rests against the wall section exclusively via the contact surface or several such contact surfaces, which can be referred to as connection points. This allows the wall section to be designed or shaped over a particularly large area, at least as part of the spherical surface, thereby significantly increasing its stiffness.

[0023] In a further embodiment, the spring support element has an opening located at its upper end, particularly when the spring support element is installed in the vehicle, and extending upwards in the direction of the vehicle's height. This opening is designed, for example, as a maintenance opening. In other words, the opening extends along the upper end of the spring support element. Specifically, the opening is designed as a through-opening. Through this opening, the spring and / or damper assembly and / or its connection, which is designed, for example, as a screw connection, can be accessed via the mounting area with the spring support element, for example, for maintenance and / or repair purposes. Furthermore, the opening can be used for assembly and / or disassembly purposes.

[0024] Preferably, the wall section, in particular the spherical layer, spherical segment, and / or spherical cutout, extends radially from the opening, particularly outwards, at least to the mounting area. In other words, the wall section, extending radially from the opening at least to the mounting area, is formed or shaped as part of the spherical surface, particularly continuously. Thus, for example, the spherical layer, spherical segment, and / or spherical cutout shape of the wall section is continuous in the radial direction from the opening to at least the mounting area. This allows the stiffness of the spring support element to be significantly increased, thereby keeping the weight of the spring support element, and consequently the weight of the vehicle, particularly low.

[0025] In a further embodiment, the wall section, which is particularly spherical in shape, spherical segment, and / or spherical cutout, extends further outwards in the radial direction of the spring support element than the mounting area. This means that the wall section projects beyond the mounting area in the radial direction. In other words, a length of the wall section located further outwards in the radial direction than the mounting area forms at least part of the spherical surface. Thus, for example, the wall section extending radially outwards from the opening beyond the mounting area, and in particular continuously, is formed as part of the spherical surface.This allows the stiffness of the spring support element to be increased significantly, which in turn allows the weight of the spring support element, and therefore in particular the weight of the vehicle, to be kept particularly low.

[0026] To keep the weight of the spring support element, particularly of the vehicle, as low as possible, a further embodiment provides for a wall thickness of the wall section of a maximum of 3 mm, in particular a maximum of 2.5 mm. For example, the wall thickness is at least 1 mm, in particular at least 1.5 mm, or at least 2 mm, for example exactly 2.5 mm. The aforementioned wall thickness can be achieved because the wall section is formed at least as part of the spherical surface. The term "wall thickness" refers in particular to the material thickness, especially the sheet thickness, of at least the wall section.

[0027] A second aspect of the invention relates to a spring support for a motor vehicle, in particular for the body of the motor vehicle. The term "spring support" refers specifically to a spring support assembly. The spring support comprises a spring support element according to the first aspect of the invention. Advantages and advantageous embodiments of the first aspect of the invention are to be regarded as advantages and advantageous embodiments of the second aspect of the invention, and vice versa.

[0028] To minimize the weight of the vehicle, and especially the spring support, in a particularly cost-effective manner, a further embodiment provides for the spring support element to be designed as an upper part. In other words, the spring support has at least one second spring support element, designed separately from the first, which, particularly when the spring support is installed in the vehicle, is located at least partially, for example, predominantly or completely, below the first spring support element. This means that the second spring support element is designed as a lower part. This allows for different shapes to be provided for the upper and lower parts. In particular, the spring support is designed or constructed using sheet metal shell construction. For example, the spring support element, or the upper part, is a first sheet metal shell of this sheet metal shell construction.Furthermore, for example, the second spring support element or the lower part is a second sheet metal shell of this sheet metal shell construction.

[0029] A third aspect of the invention relates to a motor vehicle comprising at least one spring support element according to the first aspect of the invention and / or at least one spring support according to the second aspect of the invention. Advantages and advantageous embodiments of the first and second aspects of the invention are to be regarded as advantages and advantageous embodiments of the third aspect of the invention, and vice versa.

[0030] Further features of the invention will become apparent from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown in the figures alone, are not only usable in the combinations specified, but also in other combinations or on their own.

[0031] The invention will now be explained in more detail with reference to preferred embodiments and the accompanying drawings. These show: Fig. 1 a schematic and perspective partial view of a car body which has at least one spring support element according to the invention; and Fig. 2 a schematic perspective view of a spring support element according to the invention; and Fig. 3 a schematic top view of a spring support element according to the invention; and Fig. 4 a schematic bottom view of a spring support element according to the invention; and Fig. 5 a schematic perspective view of a spring support element according to the invention and a spherical surface; and Fig. 6 a schematic side view of a spring support element according to the invention and a spherical surface; and Fig. 7 a schematic partial sectional view of a spring support element according to the invention; and Fig. 8 a schematic further partial sectional view of a spring support element according to the invention.

[0032] In the figures, identical or functionally equivalent elements are provided with the same reference symbols.

[0033] Fig. Figure 1 shows a schematic and perspective partial view of a car body 1. Therefore, the car body 1 can be described as a car body. Thus, the car is in Fig. 1 is shown in particular in part. The body 1, for example, has a body structure 2, which in this case is designed as a front structure or front end. Thus, the body structure 2 is in particular a front structure.

[0034] As in Fig. As can be seen particularly well in Figure 1, the body 1, and in particular the body structure 2, has a front wall 3 which preferably at least partially, and in particular at least predominantly or completely, defines or forms an interior space 4 of the motor vehicle, at least in the longitudinal direction 5 towards the front. The interior space, which can be referred to as the vehicle interior, is understood to be, in particular, a passenger compartment or a passenger cell. Furthermore, the body 1, and in particular the body structure 2, preferably has at least two longitudinal members 6 which, in this case, project forward from the front wall 3 in the longitudinal direction 5 of the vehicle and extend, in particular, obliquely or perpendicularly to the front wall 3. The respective longitudinal member 6 is, for example, designed as an engine longitudinal member.

[0035] The body 1, in particular the body structure 2, has at least one spring support element 7, which is located in Fig. 1 is recognizable and in Fig. Figure 2 shows a schematic and perspective representation. The spring support element 7 is, for example, a component of a spring support 8. In other words, the spring support 8, for example, includes the spring support element 7. The spring support element 7 is, for example, configured as the upper part 9 of the spring support 8. The spring support 8 also includes, for example, at least one lower part 10, which is configured separately from the spring support element 7 or the upper part 9 and can be referred to as a second spring support element.

[0036] The spring support element 7 is designed at least partially, and in particular at least predominantly or completely, as a sheet metal component. Fig. Figure 3 shows the spring support element 7 in a schematic top view, that is, viewed from above in the vehicle's vertical direction 11. Fig. Figure 4 shows the spring support element 7 in a schematic bottom view, i.e. viewed from below in the vehicle's vertical direction 11.

[0037] As in Fig. 2, Fig. 3 to Fig. As can be seen particularly well in Figure 4, the spring support element 7 has at least one mounting area 12 through which a spring and / or damper assembly, intended for coupling a vehicle wheel to the spring support element 7, in particular to the body 1, can be connected to the spring support element 7, for example, at least indirectly or directly. The spring and / or damper assembly is not shown in the figures and is designed separately from the spring support 8, in particular separately from the spring support element 7. In the exemplary embodiment, several, for example four, such mounting areas 12 are provided.In other words, the spring support element 7 has several mounting areas 12 through which the spring and / or damper assembly can be connected to the spring support element 7, for example, by means of a support bearing (not shown in the figures) or by means of several such support bearings. Each mounting area 12 is designed, for example, as a screw point, which can be referred to as a screw-in point. In other words, the spring and / or damper assembly can be screwed to the spring support element 7, particularly via the support bearing, or is screwed to it, via the respective mounting area 12. For this purpose, each mounting area 12 has, for example, a screw opening 13, which can be referred to as a screw hole or a bore.

[0038] In Fig. 2, Fig. 3 to Fig. Figure 4 shows a central axis 14 of the spring support element 7, in particular the spring support 8. The central axis 14 runs parallel to an axial direction 15 of the spring support element 7, in particular the spring support 8. For example, the fastening areas 12 are arranged in the circumferential direction of the spring support element 7 around the central axis 14, in particular distributed, for example, evenly distributed.

[0039] For example, the spring support 8, in particular the spring support element 7 or the lower part 10, has at least one second fastening area not shown in the figures, via which the spring support 8, in particular the spring support element 7 or the lower part 10, can be connected or is connected, for example at least indirectly or directly, to the body 1, in particular the body structure 2.

[0040] In order to keep the weight of the motor vehicle, and in particular the spring support element 7, as low as possible, the spring support element 7 has at least one wall section 16, which is in particular designed as a sheet metal component. The wall section 16 extends in the radial direction 17 of the spring support element 7 at least between at least one of the mounting areas 12, in particular between the respective mounting area 12, and the central axis 14. As shown in Fig. 5 and in Fig. As can be seen particularly well in section 6, the wall section 16 is formed or shaped at least as part of a, in particular imaginary, spherical surface 18, in particular a dome surface. Fig. Figure 5 shows the spring support element 7 and the spherical surface 18 in a schematic perspective view. Furthermore, in Fig. Figure 6 shows the spring support element 7 and the spherical surface 18 in a schematic side view. Fig. 5 and in Fig. Figure 6 shows the spherical surface 18 as at least partially transparent, so that the spring support element 7 is visible. Thus, the spring support element 7 has a spherical, in particular dome-shaped, basic form at least in the wall section 16, and in particular at least in the radial direction 17 between the respective mounting area 12 and the central axis 14. For example, this wall section 16 extends from the respective mounting area 12 or at least to the respective mounting area 12. It is not necessary for the wall section 16 to extend, in particular directly, to the central axis 14; rather, a distance may be provided between the central axis 14 and the wall section 16, in particular as long as the wall section 16 is arranged at least partially between the respective mounting area 12 and the central axis 14 in the radial direction 17.

[0041] The sphere surface 18 is, in particular, a surface of an imaginary sphere, so that this sphere is specifically not a component of the spring support element 7. In the Fig. In the illustration shown in Figure 5, the sphere surface 18 is designed as the surface of a hemisphere. Fig. 6 the sphere surface 18 is formed as the surface of a sphere segment.

[0042] Because the wall section 16, in particular at least partially, is formed or shaped as part of the spherical surface 18, the wall section 16 is, for example, curved or arched, at least partially. This allows the stiffness of the spring support element 7 to be particularly increased, so that, for example, the wall thickness of the spring support element 7 can be kept particularly small. This wall thickness is, for example, a maximum of 3 mm, in particular a maximum of 2.5 mm. This allows the weight of the spring support element 7 to be kept particularly low, which in turn allows the weight of the vehicle to be kept particularly low. The wall section 16, that is, in particular a spherical shape, for example, a spherical layer, spherical segment, or spherical sector shape, is also in Fig. 7 and in Fig. Figure 8 is particularly easy to see, in which the spring support element 7 is shown in a respective schematic partial sectional view. Fig. 7 and Fig. Figure 8 shows, in particular, sections in different cutting planes.

[0043] For example, the wall section 16, which is in particular spherical or dome-shaped, surrounds the central axis 14 at least partially, preferably by at least 90 degrees, for example by at least 180 degrees, in particular by at least 270 degrees.

[0044] In the present case, the wall section 16, and thus in particular the spherical or dome-shaped form, extends, at least from the respective fastening area 12, inwards in the radial direction 17 towards the central axis 14. Thus, for example, from the respective fastening area 12, which is also referred to as the connection point, inwards curved, and in particular rigid, surface profiles of the wall section 16 are provided in the radial direction 17.

[0045] In this embodiment, the respective mounting area 12 is designed as a recess 19, in particular as a embossing, extending downwards in the vehicle's vertical direction 11 relative to the wall section 16. This means that the respective mounting area 12 is offset or recessed downwards in the vehicle's vertical direction 11, at least in some areas, relative to the wall section 16. Thus, for example, embossings or grooves are provided between connection points where the spring and / or damper assembly is attached to the spring support element 7, particularly via the mounting area 12.

[0046] Preferably, the respective mounting area 12 is designed as a contact surface 20 for a support bearing (not shown in the figures) via which the spring and / or damper assembly can be connected to, or is connected to, the spring support element 7. Thus, the respective support bearing rests, in particular directly, against the respective mounting area 12 or the respective contact surface, and is connected to the spring support element 7, in particular via the respective contact surface or the respective mounting area 12. In particular, the respective spring and / or damper assembly is connected to the respective support bearing, whereby the respective spring and / or damper assembly is attached to, or connected to, the spring support element 7 via the respective mounting area 12.The respective contact surface 20 is preferably designed to be particularly small, so that the spherical or dome-shaped areas of the wall section 16 can be made particularly large, thereby significantly increasing the stiffness of the spring support element 7. This has the particular consequence that the spring support element 7, especially the wall section 16, has no large or larger membrane areas. This means that resistance to deformation under mechanical stress on the spring support element 7 can be significantly increased by the shape of the wall section 16, that is, in particular by its curved or spherical shape. This allows the spring support element 7 to be designed to be particularly stiff.

[0047] As in Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 to Fig. As can be seen particularly well in Figure 8, in the exemplary embodiment the spring support element 7 has an opening 22 arranged at an upper end 21 of the spring support element 7 in the vehicle's vertical direction 11, which is designed, for example, as a maintenance opening. An axial direction of the opening 22 preferably extends in the vehicle's vertical direction 11, in particular substantially parallel to the vehicle's vertical direction 11. In particular, the opening 22 points upwards in the vehicle's vertical direction 11. In particular, the central axis 14 and the axial direction of the opening 22 are arranged parallel to each other. Preferably, the central axis 14 extends through the opening 22. For example, the opening 22 and the central axis 14 are arranged coaxially to each other.Furthermore, it is provided that the wall section 16, in particular its spherical or dome-shaped form, extends outwards from the opening 22, in particular directly, in the radial direction 17 at least as far as the respective mounting area 12, and extends, for example, in the radial direction 17 outwards beyond the respective mounting area 12. In other words, the wall section 16 extends, for example, further outwards in the radial direction 17 than the respective mounting area 12. The spherical or dome-shaped form is thus provided, with respect to the radial direction 17, for example, at least between the opening 22 and the respective mounting area 12, but this dome-shaped or spherical form projects, for example, slightly outwards, beyond the respective mounting area 12 in the radial direction 17.

[0048] Overall, the examples demonstrate how a geometrically rigid design of the spring support element 7, for example, designed as the upper part of the spring support, can be achieved. In particular, shape optimization of the form or design of the spring support element 7 by the wall section 16, also referred to as shape optimization, is provided, especially with regard to fatigue strength and stiffness.

[0049] Naturally, it is preferably provided that the body 1, in particular the body structure 2, has several, in particular two, such spring support elements 7 and / or spring supports 8. This is in Fig.1. The spring support elements 7 and / or the spring supports 8 are spaced apart from each other in the transverse direction 23 of the vehicle and, in particular, are arranged on different sides of the vehicle with respect to the transverse direction 23. For example, the spring supports 8, in particular the spring support elements 7, are of identical construction. For example, the spring supports 8, in particular the spring support elements 7, are also connected to each other via a cross brace 24, which is formed separately from the spring supports 8 and which can be referred to as a strut brace.
