Description

  • The present invention relates to a support structure of a motor vehicle.
  • From practice, it has been known for some time, in the event 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 pillars and the like, impact energy absorbing form.
  • For example, is from 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, there is a trend towards increasing the lightweight quality of the bodyshell structure by the use of high-strength steels and / or lightweight materials such as light metals, carbon fiber composites, plastics u. a., Which, however, compared to conventional steel sheet materials have a lower ductility. In practice, it has been found that such carriers, in particular bending beams, which in turn consist of low ductility materials, abruptly collapse after reaching a certain load limit or a certain deformation state, resulting in that z. B. in a pile impact too high penetration depth of the pile is recorded, for example, in the passenger compartment.
  • The DE 10 2009 024 829 A1 discloses a bending beam of a body structure of a motor vehicle, which consists of a material of low ductility and is formed by a hollow profile. The bending beam has a predetermined breaking point, which in the case of exceeding a certain bending stress of the hollow profile allows a controlled crack initiation and / or a controlled crack formation and / or a controlled crack propagation in the profile wall.
  • The DE 198 30 026 A1 discloses a support structure of a motor vehicle with a carrier assembly which is deformable in a collision for impact energy absorption and with a vehicle part, which is fastened to a carrier of the carrier assembly with a connection part via a carrier connection as a screw connection and displaceable in a vehicle collision. The carrier connection comprises a bolt and an associated threaded plate in such a way that the bolt is positively guided by a respective through hole in the connecting part and in a support wall of certain wall thickness. In the support wall, starting from the throughbore, a displacement groove with a reduced support wall thickness and a width approximately corresponding to the diameter of the bolt extends in a predefined direction of displacement of the vehicle part which can be displaced during a vehicle collision. As a result of an impact-related force acting on the bolt, it is guided and displaced together with the connected vehicle part by releasing a positive connection and by overcoming a connecting friction connection in and along the rupturable and plowable sliding groove.
  • Against this background, it is an object of the present invention to provide an improved support structure of a motor vehicle.
  • This object is achieved by a supporting structure of a motor vehicle having the features of patent claim 1 and by the use of a supporting structure having the features of patent claim 14.
  • The invention accordingly provides a supporting structure of a motor vehicle with a bending beam, which is fastened in a form-fitting manner via a joining element to a joining partner, wherein the bending beam has a first material and adjacent to the joining element in a direction substantially opposite to that acting on the bending beam in the event of an impact Traction has an opening area in which a second material with a higher ductility than the first material is provided such that upon application of the tensile force on the bending beam in the event of an impact, the second material is compressible by the joining element for receiving deformation energy.
  • The above joining concept thus allows slippage of the bending beam in the event of a crash by a definable length upon reaching a predetermined load level. The opening region in which the second material is formed, thus serves the targeted energy reduction to provide additional deformation in the direction of force available.
  • Preferably, it is provided that the bending beam is displaceable in the event of an impact by the tensile force acting on it relative to the joining partner while compressing the second material. This allows the slipping of the bending beam in the event of a crash by a definable length upon reaching a predetermined load level.
  • According to a further preferred embodiment, it is provided that an absorption capacity of an impact energy by the bending beam is adjustable by a choice of material of the second material.
  • In the case of the choice of a reinforced material thus results in a higher absorption capacity of the impact energy by the second material, while selecting, for example, a non-reinforced material, the absorption capacity of the impact energy is lower by the second material.
  • According to a further preferred embodiment, it is provided that an absorption capacity of an impact energy by the bending beam is adjustable by a geometry of the opening area in which the second material is arranged. The geometry of the opening, in which the second material is formed, can thus be used to determine a force required to move or displace the bending support relative to the joining partner and thus to provide an absorption capability of an impact energy by the bending support. The movement can be linear or non-linear, for example.
  • Preferably, it is further provided that the joining element is guided by a formed in the bending beam through hole and a formed in the joining partner through hole. Thus, a positive connection of the bending beam is ensured with the joining partner.
  • According to a further preferred embodiment, it is provided that the opening region is formed by an elongated hole extending in the longitudinal direction of the bending beam, wherein the slot is substantially rectangular and wherein a dimension of the oblong hole in the transverse direction of the bending beam in the region of the through bore of the bending beam substantially a Diameter of the joining element corresponds. The slot preferably allows a guided, linear movement. By providing the dimension of the slot in the transverse direction of the bending beam in the order of the diameter of the joining element thus the joining element can be accurately recorded in the slot. This allows a guided, linear movement of the bending beam relative to the joining partner.
  • Preferably, it is further provided that the opening region is formed by an elongated hole extending in the longitudinal direction of the bending beam, wherein the slot is formed substantially frusto-conical and wherein a dimension of the oblong hole in the transverse direction of the bending beam in the region of the through hole of the bending beam substantially a diameter of the joining element corresponds and decreases with increasing distance from the through hole. Thus, a non-linear, in particular slowing down, displacement of the bending beam relative to the joining partner in an impact-induced force on the bending beam can be made possible. Due to the fact that the dimension of the oblong hole in the transverse direction of the bending support has a smaller dimension than the diameter of the joining element in the region distal to the through-hole, the displacing of the bending support relative to the joining partner results in a defined tearing of the first material of the bending support in the bending support distal region of the slot.
  • According to a further preferred embodiment, it is provided that the bending beam is fastened by means of a secondary, material-locking connection to the joining partner. Due to the cohesive connection, a shearing force must first be overcome in order to allow a displacement of the bending support relative to the joining partner. This also acts as an overload protection of the bending beam to avoid unwanted failure in case of excessive force.
  • Preferably, it is further provided that the bending beam is formed by a closed or open hollow profile. This ensures optimal impact energy absorption with low component weight.
  • According to a further preferred embodiment, it is provided that the joining element is formed by a rivet, screw or bolt element. Thus, depending on the requirement or installation position, a suitable joining element can be provided.
  • According to a further preferred embodiment, it is provided that the first material of the bending beam is formed of a continuous fiber reinforced plastic and the second material of the bending beam of a short fiber reinforced or non-reinforced plastic. The formation of the first material from the continuous fiber reinforced plastic allows the formation of the bending beam of a high strength material. The formation of the second material of the bending beam from the short fiber reinforced or unreinforced plastic allows the provision of the second material of a material with increased ductility.
  • Preferably, it is further provided that the joining partner is formed of a metallic material or a continuous fiber reinforced plastic. The joining partner is thus formed from a high-strength material.
  • According to a further preferred embodiment, it is provided that the bending beam is fastened via a first joining element to a first joining partner and via a second joining element to a second joining partner. Thus, both over the first joining element and the second joining element impact energy are absorbed.
  • According to a further preferred embodiment, it is provided that the support structure is used for at least partially forming a frame structure, a sill, a Türbrüstungsträgers, a column member, a bumper, in particular bumper cross member, and / or any other conceivable support a body structure of a motor vehicle. The support structure is thus versatile.
