Description

  • The The invention relates to a crash-optimized bending beam of a Body structure of a vehicle, in particular motor vehicle, according to the combination of features of the claim 1.
  • From practice, it has been known for some time, in the case of a crash event shock-loaded components of the body of a motor vehicle, such as outer side members, front and rear bumper cross members, body columns and the like. More, forming impact energy absorbing by the wall of said carrier at least partially on or a plurality of structural elements associated with a wave structure and / or the wall itself is formed by a wave structure. So is out of the EP 0 266 084 A2 a shock-absorbing box-shaped hollow profile for a motor vehicle body known whose arranged parallel to the loading direction profile walls are formed by a wave structure, wherein the waves of said wave structure in the plane of the respective profile wall extending linearly in the loading direction. Furthermore, the US 5,340,178 A a bumper beam in the manner of a box-shaped hollow profile in the interior of which is arranged on opposite walls of the hollow profile elongated structure with wave-shaped respectively S-shaped cross-section is arranged, whose shafts extend transversely to the loading direction. Further, with the EP 0 912 374 B1 and EP 1 892 159 A2 corrugated tubular absorption body for receiving impact energy disclosed, which in turn act in the event of a collision on components of a vehicle body by deformation of the wave crests and troughs. Finally, out of the EP 1 878 620 A1 a bumper assembly for a vehicle with an absorber known, which in turn is designed as an elongated box-shaped hollow profile mehrwandig, wherein in the cavity formed between adjacent walls a corrugated metal foil is arranged, the waves extend transversely to the direction of loading linearly.
  • It there is a trend towards increasing the lightweight construction quality the bodyshell structure through the use of high-strength steels and / or lightweight materials, such as light metals, carbon fiber composites u. a., Which, however, compared to conventional steel sheet materials have a lower ductility. In practice was found that such carriers, in particular bending beams, which, in turn, consist of low ductility materials Reaching a certain load limit or a specific Abruptly collapse the deformation state, d. h., "catastrophic" fail can, resulting in that z. B. at a try carried out pile impact, too high a penetration depth of the pile is recorded for example in the passenger compartment. This is where the invention described below begins.
  • task The invention is one of a material of low ductility existing bending beam of a body structure of a Vehicle, in particular motor vehicle, with regard to a possible To optimize crash event in such a way and further, that the disadvantages described above, d. h., an abrupt collapse the same, accompanied by too high penetration depth of the crash opponent is largely avoided in the body structure.
  • Of the Invention is based on the finding that controlled by Tearing the profile wall advantageous impact energy absorbed and an abrupt collapse of the bending beam can be prevented.
  • The Asked task is therefore with a crash-optimized bending beam a body structure of a vehicle, in particular motor vehicle, solved, which consists of a material of low ductility exists and formed by a closed or open hollow profile is, in the event of a possible crash event as a result of certain force acting on the same "F" one Bending stress is subject, at least one parallel or largely arranged parallel to the loading direction profile wall said hollow profile at least locally at least one wave structure and wherein at least one trough and / or a wave crest the at least one corrugated structure at least one predetermined breaking point which, in the case of exceeding a certain bending stress the hollow profile controlled crack initiation and / or a controlled cracking and / or controlled crack propagation allowed in the said profile wall.
  • By Controlled crack initiation, controlled cracking and / or the controlled crack propagation, as above indicated, an abrupt collapse of the said bending beam made of a material low ductility effectively avoided. The controlled tearing of the profile wall will be advantageous Impact energy absorbed, which is further advantageous to the effect that the penetration depth of a crash opponent is significantly reduced in the body structure of the vehicle.
  • The Subclaims describe preferred developments or Embodiments of the invention.
  • Thereafter, said predetermined breaking point by material thinning the profile wall and / or formed by one or more recesses in the same, which can be accomplished easily and inexpensively, wherein the degree of material thinning and the required number of recesses and their shape depending on a certain abutment force "F" mathematically and / or empirically in the context of Try can be determined.
  • According to one first advantageous embodiment variant of the invention can the waves of at least one wave structure in the plane of said profile wall extend linearly transversely to the loading direction, which is an extremely simple and inexpensive represents to bewerkstelligende design. In contrast, can according to a second advantageous Embodiment variant of the invention, the waves of at least one wave structure but also in the plane of the said profile along a wall Curve track, whereby the crack and thus energy absorption behavior the bending beam in case of a possible crash event even better is adjustable. Same or similar is to note if the waves of at least one wave structure According to a further embodiment variant of Invention concentric in the plane of the said profile wall Form circles and / or sections of circle.
  • One Such crash-optimized bending beam can from a high-strength steel, a light metal, a carbon fiber composite plastic (CCFRC = Continuous Carbon Fiber Reinforced Composite) or any other known per se suitable material with low ductility consist.
  • Especially advantageously offers such a crash-optimized bending beam at least partially forming a frame structure, a sill, a door balustrade, a column element, a bumper, in particular bumper cross member, and / or any other conceivable carrier or bending carrier of the Body structure of a vehicle, in particular motor vehicle, at.
  • The The invention will be described below with reference to the drawings illustrated embodiments explained in more detail. Show it:
  • 1 the perspective view of a bending beam of a body structure of a vehicle according to the prior art at the beginning of a three-point bending test,
  • 2 the perspective view of two bending beams of different material according to the prior art immediately after the bending test according to 1 .
  • 3 3 the sectional view of a bending support according to the invention designed according to a first advantageous embodiment variant,
  • 4 the detail "Z" after 3 .
  • 5a , b very schematically the perspective view of the bending beam after
  • 3 immediately before and during said bending test,
  • 6a very schematically the perspective view of a second advantageous embodiment variant of a bending support according to the invention formed immediately before and during said bending test,
  • 7a very schematically the perspective view of a third advantageous embodiment variant immediately before and during said bending test, and
  • 8th the perspective view of an inventively designed Biegeträgers according to a fourth advantageous embodiment variant.
  • 1 shows one in a two supports 1 . 2 and a post stamp 3 having three-point bending device 4 clamped bending beam of a body structure of a vehicle, in particular motor vehicle, which in this case by a box-shaped closed hollow profile 5 is formed, at the beginning of a three-point bending test. By means of the bending test, for example, under the action of a certain force "F", a pile impact of a vehicle, in particular a motor vehicle, and the load reaction of the bending support or of the hollow profile are intended 5 be simulated.
  • In order to absorb impact energy advantageously in the event of a crash event of the motor vehicle, for example in the manner of a pile impact, the profile wall has 6 of the hollow profile 5 as is known, at least locally one or more wave structures 7 on, where are the waves of the wave structures 7 in the plane of said profile wall 6 transverse to the loading direction 8th (Force direction arrow of the kick-off force "F") linearly extend.
  • Often, as already discussed in the introduction, to increase the lightweight construction of the bodyshell structure of a vehicle, in particular motor vehicle, high strength steels and / or lightweight materials, such as light metals (aluminum or the like), known per se carbon fiber composite plastics (CCFRC = Conti nuous Carbon Fiber Reinforced Composite), which, however, have lower ductility than conventional steel sheet materials.
  • In In practice, it has now been found that such materials low ductility existing bending beam after Reaching a certain load limit or a specific Abruptly collapse the deformation state, d. h., "catastrophic" fail can, resulting in that z. B. at a try carried out pile impact, too high a penetration depth of the pile, for example, in the passenger compartment of the vehicle is recorded.
  • That's how it shows 2 in the figure above a deformed as a result of a three-point bending test and collapsed bending beam made of aluminum or an aluminum alloy and including a correspondingly deformed bending beam of said carbon fiber composite plastic.
  • To address the problem described above, have at least one trough 7a and / or a wave mountain 7b the wave structure 7 ' . 7 '' the profile wall 6 of the hollow profile 5 at least one predetermined breaking point 9 in the case of exceeding a certain bending stress of the hollow profile 5 due to the applied force "F" a controlled crack initiation and / or a controlled cracking and / or a controlled crack propagation in the profile wall 6 allow ( 3 to 8th ).
  • According to the 3 and 4 are present exclusively in the troughs 7a the wave structure 7 ' the profile wall 6 of the hollow profile 5 said breaking points 9 provided, whereby the same by a material thinning of the profile wall 6 in the trough 7a are formed by the material thickness "s 1 " of the wave crest 7b greater the material thickness "s 2 " of the wave trough 7a is selected (s 1 > s 2 ).
  • Said material thinning can thereby over the longitudinal extent of the wave structure 7 ' be formed differently and / or from wave to wave, in this case of wave trough 7b to wave trough 7b , which makes it even finer on the crack and thus energy absorption behavior of the bending beam or its profile wall 6 Influence can be taken.
  • However, the invention is not limited to this specific embodiment, but also covers hollow sections 5 in which only the wave crests 7a or where both the troughs 7b as well as the wave mountains 7a said breaking points 9 have (not shown).
  • Furthermore, the invention is not limited to said box-shaped hollow profile 5 but captures any suitable closed or open hollow section 5 a bending beam. So can said hollow profile 5 for example, be designed as a U-profile (not shown in detail).
  • In extensive experiments it was found that by a special course of the waves of the wave structure 7 ' in the plane of the relevant profile wall 6 the crack and thus energy absorption behavior of the bending beam or the hollow profile 5 can be set even better in the event of a possible crash event.
  • So show the 5a and 5b first a bending beam with a box-shaped hollow profile 5 in which both parallel or largely parallel to the loading direction 8th arranged profile walls 6 wave structures 7 ' having waves, which in turn in the plane of the profile wall 6 transverse to the loading direction 8th extend linearly, whereby 5b in the event of a crash, cracks appear 10 in the profile wall 6 starting from the force application area 11 as a result of a crash event, in particular along the predetermined breaking points 9 respectively along the material thinning of the troughs 7a train progressively.
  • In contrast, however, it can also according to the 6a and 6b and or 7a and 7b be shown to provide waves, which are in the plane of the profile wall 6 along a curved path ( 6a . 6b ) or concentric circles and / or circular sections ( 7a . 7b ) train. Again, starting from the force application area 11 of the hollow profile 5 Controlled crack initiation, controlled cracking and / or controlled crack propagation along the material thinning of the troughs 7a to record.
  • The embodiment according to 8th differs from the preceding essentially in that instead of predetermined breaking points 9 in the form of material thinning now a plurality of successively arranged in series recesses 12 in the troughs 7b the wave structure 7 '' the profile wall 6 are provided. These, too, in the event of an impact force "F" acting on the bending beam due to the crash, bring about controlled crack initiation, controlled cracking and / or controlled crack propagation in the profile wall 6 ,
  • By local variation of the number of said recesses 12 over the longitudinal extent of the wave structure 7 '' and / or by varying the number of recesses 12 from wave to wave, in this case from Wellental 7b to wave trough 7b , still can finer on the crack and thus energy absorption behavior of the bending beam or its profile wall 6 Influence can be taken.
  • Of the inventive or crash-optimized bending beam is particularly suitable for at least sections of training a frame structure, a sill, a door balustrade, a column element, a bumper, in particular bumper cross member, and / or any other conceivable carrier of the body structure a vehicle, in particular motor vehicle, which in the event of a crash bending dominant is claimed.
