Definitions
- the invention relates to a bumper cross member with
- each widening element has a U-shaped profiled connecting section with a contact section
- the connecting section has a profile base connecting two legs of the U-shaped profile and is engaged with one of the two U-shaped sections of the carrier profile and is arranged so that it overlaps in the y-direction and
- connecting section is connected to the profile base of the carrier profile at least in the region of its contact section
- a vehicle equipped with at least one such bumper cross member is also described.
- a bumper cross member is known from the generic publication US Pat. No. 9,902,349 B2, at the end of which there is an extension and a V-shaped bracket supported on a crash box and on a section of the extension.
- bumper cross member is known from DE 10 2017 222 081 A1.
- the crossbeam widening elements are placed butt against the ends of the beam profile and are designed to lengthen the profiling of the beam profile.
- bumper cross members of different widths can be provided for different motor vehicles using the carrier profile as a common part.
- the widening elements have tabs as profile extensions in the vehicle transverse direction (y-direction), namely a middle tab for connecting to the carrier profile and an upper and lower tab for connecting the widening element to a crash box arranged on the carrier profile.
- This connection system enables quick and easy assembly of the cross member extension elements with the carrier profile.
- the disadvantage of this bumper cross member is that, especially under high loads, such as a high-speed crash, the connection between the cross member and the carrier profile is not sufficiently stable and the cross member widening elements can tear off the carrier profile, causing damage to both the Vehicle and the risk of injury to vehicle occupants increases significantly. It would also be desirable to have fewer restrictions on the design of the extension elements.
- the invention is therefore based on the object of developing a bumper cross member of the type mentioned at the outset in such a way that it satisfies the requirements of different vehicle designs through the use of different widening elements and in which the design freedom for different vehicles and crash situations is also increased in terms of adaptation.
- each widening element has a mating section adjoining the abutment section and an extension section adjoining the mating section
- connection section in the region of its fitting section with its limbs at least partially contacts the limbs of the carrier profile.
- x-direction, y-direction and z-direction correspond to the directions as they are usually used in vehicles.
- the x-direction corresponds to the longitudinal extension of the vehicle, the y-direction to the transverse direction of the vehicle and the z-direction to the direction of the vertical axis.
- connection between the widening element and the carrier profile takes place as a profile-in-profile solution, in which the connection section is arranged with its contact section and its fitting section overlapping with the profiled section in the end area of the carrier profile and is engaged with it.
- the actual extension section provided for the extension of the carrier profile can be designed very individually, which relates to the geometric shape, the mechanical strength or the material.
- the widening element is usually designed in one piece. This can also be composed of several components.
- the complementary profile sections are plugged into one another.
- the connecting section can be arranged on the outside around the U-shaped profile of the carrier profile or on the inside of it. This possibility also means that the freedom of design in the design of such a widening element is less restricted than previously known configurations.
- the legs of the connecting section in the region of its fitting section each with their outside pointing away from the legs with an inside lying between the legs of the Legs of the carrier profile are in contact and the side facing away from the legs of the profile base of the connecting section is connected, typically welded, at least in the area of the contact section to the inner side of the profile base of the carrier profile.
- the connecting section of the widening element is located within the profiling of the carrier profile.
- the already existing cavity in the carrier profile is used, so that no additional installation space is required for the connection of such an expansion element.
- the U-profile connecting section of the widening element comprises a contact section and a fitting section.
- the fitting section With regard to its U-shaped profile and thus the span and alignment of its legs, the fitting section is designed such that these contact the legs of the U-shaped profiled end section of the carrier profile. A fit for connection to the carrier profile is thus provided by the fitting section.
- the contact section which is typically much longer than the fitting section and extends in the y-direction, only needs to be connected with its profile base to the profile base of the carrier profile.
- the widening element can be fastened with its connecting section to the carrier profile with a two-point fastening, in which case the two fastening points can be spaced far apart in the y-direction, in accordance with the length of the connecting section in y -Direction.
- a first attachment point can be located, for example, on the free end face of the profile base of the contact section, at which point the widening element is typically joined to the profile base of the carrier profile by welding.
- the second attachment point is effected by the fit provided by the fitting section and only needs to be secured against the direction in which the widening element is engaged with its connecting section with the carrier profile, typically also by a weld that can be made at several points Spot welds can be realized.
- connection section of the widening element allows the connection section of the widening element to be designed such that its connection section only bears against the carrier profile with a relatively small-area contact surface.
- the legs of the connecting section which are provided for reinforcement, do not necessarily have to rest against the legs of the carrier profile. The smaller the contact surface between the two elements, the lower the risk of corrosion occurring between the two parts. If the legs of the contact section are spaced apart from those of the carrier profile, a corrosion protection layer applied, for example, by cathodic dip painting can also reach the mutually facing sides of the legs of the two U-shaped profiled parts.
- connection section of the widening element is located within the U-shaped profile of the carrier profile in its end section
- a design of the contact section allows it to also be arranged so that it overlaps with the end face of a crash box connected to the rear of the carrier profile. In this way, a force acting on the bumper cross member in the outer region can be introduced at least partially into the crash box on the front side via the widening element.
- the extension section can be designed in virtually any way.
- the U-shaped profile of the connecting section will continue into the extension section.
- the extension section can also continue the profiling of the carrier profile in the y-direction.
- the extension section can be used to extend the extension of the carrier profile in the y-direction with other cross-sectional geometries. For example, the extent of the extension section in the z-direction can exceed that of the carrier profile, either upwards and downwards or only upwards or downwards.
- extension section can also be profiled differently in the x-direction compared to the carrier profile if a different deformation behavior is to be set up in the outer edge regions of the bumper cross member.
- the extension element can represent the end of the bumper cross member with its end pointing away from the carrier profile in the y-direction.
- extension element is also the possibility of using such an extension element as an intermediate or connecting piece between the carrier profile and a separately manufactured bumper cross member end piece. The latter is typically connected to the widening element by a joining process, but can also be connected to it with mechanical connectors. Adhesive connections are also possible.
- the design of the widening element allows the carrier profile to be lengthened in the y-direction without necessarily having to accept a weak point, as is the case in the prior art.
- a widening element can be designed with a predetermined buckling point, for example by weakening the material in the legs of the widening element, for example by corresponding incisions or material cutouts.
- a predetermined buckling point can be set up at virtually any position in this section and is not limited to the end of the carrier profile.
- the buckling axis of such a predetermined buckling point does not necessarily have to run strictly in the z-direction, even if this will be the case in many cases. If the material weaknesses in the two legs, caused for example by cutouts, are not aligned one above the other in the z-direction, buckling of the outer section of the bumper cross member in the direction of the vehicle can also be combined with a component in the z-direction.
- the connecting section has a slot-like recess following its longitudinal extent (y-direction) in the region of its contact section. This is arranged in the profile base of the contact section.
- the contact surface between the two components is additionally reduced by the slot-like recess.
- such a recess which typically extends in the y-direction be used to weld the profile base of the connecting section to that of the carrier profile, preferably along at least one longitudinal side of such a slot-like recess.
- a reduction in the weight of the widening element is also achieved by such a recess.
- the carrier profile is designed as a hat profile and the legs of the U-shaped profiled connecting section of the widening element extend at least in sections up to the plane of the flanges that are flared in the z-direction opposite the U-shaped profiled section of the carrier profile.
- the carrier profile is closed with a locking plate.
- the locking plate is joined to the flanges of the carrier profile and the legs of the widening element in the area of its connecting section and/or in the area of its extension section. In these sections, the locking plate thus provides a double box profile and thus a section with particularly high flexural strength.
- Bringing the legs of the U-shaped profile of the extension section up to the striker plate can be used to simplify assembly of a striker plate.
- the free ends of the legs of the widening element protrude up to the plane formed by the flange-like free ends of the carrier profile, so that they butt against the striking plate and the striking plate can be supported on them.
- the legs of the U-shaped profiled extension section protrude somewhat in sections relative to the plane of the outer end of the carrier profile.
- These leg extensions can be used to fix a locking plate which engages with a section, such as a tab, between the two leg extensions.
- the locking plate contacts the two leg extensions with its tab pointing in the z-direction and reaching between the leg extensions and is thereby fixed in the z-direction.
- Leg extensions of this type can also be used if the locking plate has a height (extension in the z-direction) that exceeds the distance between the leg extensions and has corresponding openings into which the leg extensions engage. In both cases, not only is this locking plate section fixed in place, but the leg extensions also allow both parts to be joined from the front of the locking plate.
- the widening element can have two support arms which are arranged at a distance from one another in the vertical direction (z-direction) and extend in the longitudinal direction out of the legs and away from the carrier profile.
- the extension section is usually also designed in the shape of a hat in cross section.
- the support arms can be designed as legs extending in the longitudinal direction over the base of the profile.
- An additional extension element can be connected to the support arms.
- the support arms can also be used without an additional extension element if they are closed at the front with a locking plate. Then the carrier profile extension is designed to be lighter.
- Such a bumper cross member can be optimally adapted with regard to the requirements of different crash tests. This applies to both the high-speed small overlap test and the mobile progressive deformable barrier test (MPDB test).
- MPDB test mobile progressive deformable barrier test
- This adaptation can also be provided with regard to the arrangement and design of a predetermined buckling point. As already explained above, this can be provided by weakening the material in the extension section of the widening element. A predetermined buckling point also occurs where the contact section of the widening element ends if it does not overlap with the end face of the crash box. In order to pass such a test, it is important for the bumper cross member to have a high level of rigidity in the area of the widening elements.
- the widening element has predetermined buckling points, as already outlined above. which are arranged in particular in the area of the extension section and allow a buckling movement of a buckling section of the extension section about a predetermined buckling axis aligned in the vertical direction (z-direction).
- FIG. 1 a perspective view of a first embodiment of a bumper cross member
- Fig. 2 a vertical section through the fitting section of the bumper cross member from Figure 1,
- Fig. 3 in a horizontal section, the bumper cross member from Figures 1 and 2,
- Fig. 6 in a perspective view, a third embodiment of the bumper cross member and
- FIG. 1 shows a section of a bumper cross member 1, specifically in its end section pointing to the left in the direction of travel.
- the bumper cross member 1 comprises a U-shaped profiled carrier profile 2, a likewise U-shaped profiled widening element 3 and a profiled extension element 4 connected to the widening element 3.
- a crash box 5 is located on the rear of the carrier profile 2 at a distance from its end closure connected. At its connection end on the vehicle side, the crash box 5 carries a mounting plate 6 for connecting it to the vehicle.
- a locking plate 7, which represents the outer end of the carrier profile 2 is used to close the carrier profile at the front.
- the other end section of the bumper cross member 1 that is not shown in the figure is designed in exactly the same way as the one shown, so that the following explanations apply equally to the other end of the bumper cross member 1.
- the carrier profile 2 has a hat-shaped profile in cross-section over its entire length and thus also in its end sections, so that in addition to its already mentioned U-shaped profile, it has flanges protruding from the legs in the z-direction.
- the striking plate 7 is connected to this.
- the U-shaped profiling of the carrier profile 2 comprises two legs 9, 9.1 and a profile base 10 connecting the two legs 9, 9.1.
- connection section 11 of the widening element 3 comprises a contact section 12 and a fitting section 13 adjoining the contact section 12.
- An extension section 14 adjoins the connection section 11. While the connecting section 11 with its contact section 12 and the fitting section 13 are arranged overlapping with the end section 8 of the carrier profile 2, the extension section 14 protrudes in the longitudinal direction (y-direction) of the carrier profile 2 beyond the free end of the end section 8 of the carrier profile 2.
- the longitudinal extension of the carrier profile 2 is lengthened by the extension section 14, and the bumper cross member 1 is therefore widened.
- the widening element 3 is profiled essentially U-shaped in cross section and has two legs 16, 16.1 and a profile base 15 connecting the two legs 16, 16.1.
- the widening element 3 is narrower in the vertical direction (z-direction) than the fitting section 13 and the extension section 14 .
- the widening element 3 has a hat-shaped profile, in that flanges formed on the free ends 24 of the legs 16, 16.1 in the z-direction are provided. The front of these flanges is flush with the flanges of the hat-shaped profile of the carrier profile 2.
- the span of the legs 9, 9.1 of the widening element 3 in the area of its contact section 12 is smaller than in the fitting section 13 arranged adjacent thereto.
- the transition between the two leg widths is provided by a transition section 20 designed as a bend.
- the representation of Figure 1 makes it clear that to compensate for tolerances, the widening element 3 can be set up with regard to the depth of its immersion in the profile of the carrier profile 2 (in the y direction), since the fitting section 13 in the extension section 14 without a change in the span the leg 16, 16.1 merges.
- the viewing direction of the cut is in the direction of carrier profile 2.
- the profile base 15 of the contact section 12 and the fitting section 13 rests with its outside 21 on the inside 22 of the profile base 10 of the carrier profile 2 .
- the profile bases 10, 15 are welded together (not shown).
- the crash box 5 is also welded (indicated by weld seams 29) to the carrier profile 2, which has a recess corresponding to the U-shaped profile on its end face facing the carrier profile 2.
- the widening element 3 of the exemplary embodiment shown has material recesses 31 introduced into the legs 16, 16.1 at opposite positions in the area of its extension section 14 (see FIG. 1).
- the two opposing material recesses 31 aligned with one another in the z-direction form a buckling axis (not shown) extending in the vertical direction (z-direction). If a force acting on the outside of the bumper cross member 1 in the area of the material cutouts 31 exceeds the holding torque provided, the widening element 3 with the extension element 4 buckles about the buckling axis formed by the material cutouts 31 in the direction of the crash box 5 .
- the material recesses 31 can be seen in the longitudinal section of the section of the bumper cross member 1 shown in FIG.
- This illustration shows the bumper cross member 1 in a horizontal section. It can be clearly seen that in this exemplary embodiment the contact section 12 of the widening element 3 extends in the longitudinal direction (y-direction) up to the end face 25 of the crash box 5 and overlaps with it. In this case, the contact section 12 does not overlap the end face 25 completely, but rather only by approximately 30% of the extent of the crash box 5 in the y-direction in the exemplary embodiment shown.
- the widening element 3 has a hat-shaped cross-section—as already explained above (see FIG. 2), so that the free ends 24 of the legs 16, 16.1 are present in the area of the extension section 14 as flanges extending in the z-direction. with which the locking plate 7 is welded.
- the locking plate 7 in the area of the contact section 12 and the fitting section 13 is not in contact with the free ends 24 of the legs 16, 16.1 of the widening element 3, but only at the free ends 24 of the legs 16, 16.1 in the Area of the extension section 14.
- the locking plate 7 has a tab 26 on its free end pointing in the y-direction, which is connected to the extension element 4. laps.
- This overlapping area of the extension element 4 is set back slightly in relation to its end extending towards the free end of the bumper cross member 1, namely by the material thickness of the striking plate 7, so that the outside of the striking plate 7 is flush with the front side of the extension element 4 (see Figure 3).
- FIG. 4 shows a second exemplary embodiment of a bumper cross member
- extension section 14.1 does not have a hat-shaped profile in cross section and therefore also no flange-like free ends on the legs. Instead, at the free ends are the legs
- 16.2, 16.3 projections 27, 27.1 are arranged, through which the height of the legs 16.2, 16.3 is extended. These projections 27, 27.1 are used to fix the locking plate 7.1, which has an opening 32 at the appropriate point for this purpose.

- This bumper cross member 1.2 differs from the bumper cross member 1.1 in the design of the extension section 14.2 of its widening element 3.2. No additional extension element is provided for the bumper cross member 1.2.
- An additional lengthening is provided by two support arms 28, 28.1 continuing the legs 16.4, 16.5. These support arms 28, 28.1 extend the legs 16.4, 16.5 in the y-direction.
- the widening element 3.2 has no profile base.
- projections 27.4, 27.5 that also increase the height of the support arms 28, 28.1 are integrally formed thereon.
- the locking plate 7.2 has a tab 26.1 that is longer than the tab 26 of the bumper cross member 1.1.

- the locking plate 7.2 is fixed between them in the z-direction.
- the root of the tab 26.1 borders against the end of the projections 27.2, 27.3 pointing to the carrier profile 2.2.
- FIG. 7 shows the exemplary embodiment from FIG. 6 in a horizontal section.
- the connection between the carrier profile 2, 2.1, 2.2 and the respective widening element 3, 3.1, 3.2 takes place via the respective fitting section 13, in which the legs 16, 16.1, 16.2, 16.3 of the widening element 3, 3.1, 3.2 in the area of the fitting section 13 rest against the legs 9, 9.1 of the carrier profile 2, 2.1, 2.2.
