Description

本発明は、少なくとも2つの自動車下部支持体からなる組立体と、2つの自動車前部ユニットからなる組立体とに関する。   The present invention relates to an assembly comprising at least two automobile lower supports and an assembly comprising two automobile front units.

衝突時に歩行者を守るための下部支持体はすでに従来技術で知られている。このような下部支持体は一般的に歩行者の脛骨の高さに位置付けられ、衝突時に歩行者の膝の屈曲を制限することによって歩行者を救う。よってこのような下部支持体は、それらを車両の残余に対し可能な限り少なく後退させるため、十分に遠く前方に配置される。   Lower supports for protecting pedestrians in the event of a collision are already known in the prior art. Such a lower support is generally located at the height of the pedestrian's tibia and rescues the pedestrian by limiting the pedestrian's knee flexion in the event of a collision. Such lower supports are therefore arranged sufficiently far forward to retract them as little as possible relative to the rest of the vehicle.

自動車モデルがますます多様化していること、そして各モデルに特有の部品の数を増やすことを避け、代わりにあるモデルから別のモデルにかけて部品の規格化を試みてその設計・製造コストを抑えることが、製造業者にとって有利であることもまた知られている。特に、異なる前部形状を有する車両に載置するにあたり相応しい標準下部支持体を製造することは、経済的に言って特に有利であろう。   Avoid increasingly diversifying car models and increasing the number of parts unique to each model, instead trying to standardize parts from one model to another to reduce their design and manufacturing costs However, it is also known to be advantageous for the manufacturer. In particular, it would be particularly advantageous economically to produce a standard lower support suitable for mounting on a vehicle having a different front shape.

しかしながら現在の下部支持体は、特に以下の2つの理由から、それらが載置される車両モデルに特有である。   However, current lower supports are specific to the vehicle model on which they are mounted, especially for the following two reasons.

第1に、シールドはモデルごとに多かれ少なかれ湾曲しており、さらに下部支持体は歩行者を救うため前部にて可能な限り低くする必要があるため、シールドの湾曲に可能な限り近似する形で湾曲する下部支持体を提供する必要がある。   First, the shield is more or less curved from model to model, and the lower support needs to be as low as possible in the front to save the pedestrian, so it approximates the shield's curvature as much as possible. There is a need to provide a lower support that bends at.

さらに、ダナー(Danner)衝突(毎時15キロメートル(kph)での「保険」衝突)または高速度での衝突に備えるためには、下部支持体を通じて車両の下部サイドメンバーに至る力の伝達により車両の長手方向以外の方向で応力を制限することが重要であり、その理由は、車両の長手方向に対し、すなわち車両の進行方向に対し、垂直でない障害物に対して衝突が起こる場合には特に、このような応力によってサイドメンバーが不安定になるからである。各下部支持体は、これが固定される車両の構造物の不安定化を避けるため極端に硬直となることを避けつつ、なお衝突から歩行者を保護するこれの機能を適切に果たすように、設計される。   In addition, in order to prepare for a Danner crash (an “insurance” crash at 15 kilometers per hour (kph)) or a collision at high speed, the transmission of the force through the lower support to the lower side member of the vehicle It is important to limit the stress in directions other than the longitudinal direction, especially if the collision occurs against an obstacle that is not perpendicular to the longitudinal direction of the vehicle, i.e. to the direction of travel of the vehicle, This is because the side member becomes unstable due to such stress. Each lower support is designed to properly perform its function of protecting pedestrians from collisions while avoiding extreme stiffness to avoid destabilizing the vehicle structure to which it is secured Is done.

しかしながら、ある特定の車両モデルで、同モデルの形状の特有の細部に下部支持体を適合させることによってそのような設計に取り組むことは可能であるが、そのような細部は当然無視されるため、規格化の目的でこれを再使用することはできない。   However, in certain vehicle models, it is possible to tackle such a design by adapting the lower support to the specific details of the shape of the model, but such details are naturally ignored, It cannot be reused for standardization purposes.

本発明は、形状の異なる前部ユニットを有する車両に載置するにあたって相応しい標準下部支持体を、高速度での衝突時にこのような車両を不安定化させずに、提供することを目指す。   The present invention aims to provide a standard lower support suitable for mounting on a vehicle having a front unit of different shape, without destabilizing such a vehicle during a collision at high speed.

この目的を達成するため本発明は、少なくとも2つの自動車下部支持体からなる組立体を提供し、各下部支持体は、同一組立体の他の任意の下部支持体のクロスメンバーと交換可能なクロスメンバーと、クロスメンバーを車両の構造物へ接続するための接続手段とを備え、組立体は、各下部支持体が車両の形状へ整合するための整合部分を含み、整合部分は同一組立体の下部支持体ごとに異なること、そして接続手段がプラスチック材料を含有することを特徴とする。   To achieve this object, the present invention provides an assembly of at least two automobile lower supports, each lower support being a cross that is interchangeable with a cross member of any other lower support in the same assembly. A member and connecting means for connecting the cross member to the vehicle structure, the assembly including an alignment portion for each lower support to align with the shape of the vehicle, the alignment portion of the same assembly It is different for each lower support and the connecting means contains a plastic material.

したがって本発明は、形状の異なるシールドを有する車両に設置する2つの下部支持体からなる組立体を提供するものであって、しかしながらこの下部支持体の一部として、両車両に共通のクロスメンバーを有する。下部支持体のこの標準部分は、これを車両の形状へ整合させるための整合部分と関連しており、その結果下部支持体は、これが載置される車両の各モデルの特有の細部に整合し続ける。加えて、接続手段はプラスチック材料を含有することで、所定の力限界あたりで変形または破裂するのに適するため、本発明の下部支持体は、これが搭載される車両の構造物を不安定化させずに、ダナー衝突へ、または高速度衝突へ、晒すことができる。   Therefore, the present invention provides an assembly consisting of two lower supports installed on a vehicle having shields of different shapes. However, as a part of the lower support, a cross member common to both vehicles is provided. Have. This standard part of the lower support is associated with an alignment part for matching it to the shape of the vehicle, so that the lower support matches the specific details of each model of vehicle on which it is mounted. to continue. In addition, since the connecting means contains a plastic material and is suitable for deformation or rupture around a predetermined force limit, the lower support of the present invention destabilizes the structure of the vehicle on which it is mounted. Without being exposed to a Danner collision or a high speed collision.

さらに下部支持体を複数の部品に細分化することにより各部品の機能を最適化することが可能となり、クロスメンバーはこれに十分な安定性を与える1つの材料または1組の材料で作られ、他方整合部分はより軽く成形がより容易い材料で作られる。   Furthermore, it is possible to optimize the function of each part by subdividing the lower support into a plurality of parts, and the cross member is made of one material or a set of materials that give it sufficient stability, On the other hand, the alignment portion is made of a material that is lighter and easier to mold.

用語「クロスメンバー」は、車両の構造物へ下部支持体を接続する手段間の距離以上の距離にわたって、車両に対し幅方向に延在する構造部分を意味するために使われる。   The term “cross member” is used to mean a structural portion that extends in the width direction relative to the vehicle over a distance greater than or equal to the distance between the means for connecting the lower support to the vehicle structure.

クロスメンバーが「交換可能」と述べることにより、クロスメンバーは、車両の形状に整合するための部分から孤立させ機能的に分離でき、さらに下部支持体の仕様に定める性能を変えることなく、本来のクロスメンバーの代わりに、そしてこれに取って代わり、同一組立体の下部支持体に載置できるものと理解されたい。   By stating that the cross member is “exchangeable”, the cross member can be isolated and functionally separated from the part that matches the shape of the vehicle, and without changing the performance defined in the specifications of the lower support, It should be understood that instead of and in place of the cross member, it can be placed on the lower support of the same assembly.

用語「車両の構造物へ・・・接続するための接続手段」は、特に衝突時に、そのクロスメンバーで受けた力を車両の構造物へ伝達する下部支持体部分を指す。これらの接続手段はプラスチック材料を含むため比較的に柔軟であり、車両の構造物へ、これを不安定にする可能性がある力を伝達しない。加えて接続手段は、サイドメンバーの延長部分または衝撃吸収器を含んでよく、これにより受け取ったエネルギーのごく一部を吸収する能力を与える。   The term "connecting means for connecting to the vehicle structure" refers to the lower support portion that transmits the force received by the cross member to the vehicle structure, particularly in the event of a collision. These connecting means are relatively flexible because they contain plastic material and do not transmit forces to the vehicle structure that could destabilize it. In addition, the connecting means may include side member extensions or shock absorbers, thereby providing the ability to absorb a small portion of the received energy.

車両構造物は、車両のサイドメンバー、車両の架台に接続された下部サイドメンバー、サイドメンバーの下にこれと平行に延在するアーム、サイドメンバーの受け面と見当が合う下向き延長部、さらに言えばフロントエンドモジュールを含んでよい。   The vehicle structure includes a vehicle side member, a lower side member connected to the vehicle base, an arm that extends parallel to the lower side of the side member, a downward extension that matches the receiving surface of the side member, and more A front end module.

本発明の好ましい実施形態において、各クロスメンバーは梁である。よって梁は標準であって、これを異なる車両台に載置することを可能にする曲率と寸法とを有する。加えて梁は、衝突時に屈曲状態で働くように構成される。   In a preferred embodiment of the present invention, each cross member is a beam. The beam is therefore standard and has a curvature and dimensions that allow it to be mounted on different vehicle platforms. In addition, the beam is configured to work in a bent state upon impact.

別の実施形態においてクロスメンバーは板であって、任意に強化されてよい。   In another embodiment, the cross member is a plate and may optionally be reinforced.

本発明の一実施形態において、各整合部分は車両の進行方向にそれぞれ異なるサイズを呈する。   In one embodiment of the present invention, each matching portion has a different size in the traveling direction of the vehicle.

車両の形状へ整合するための各部分は任意に、クロスメンバーと車両バンパースキンとの間に残された空の空間を占めるためのスペーサを含む。バンパースキンのすぐ後ろに位置するこのスペーサは各車両モデルに特有であるから、これの湾曲に正確に整合できる。空間は衝突中に圧縮状態で働くよう構成され、その結果これは力限界に速やかに達し、この力限界を上回ると歩行者の脚に旋回が生じる。   Each part for matching to the shape of the vehicle optionally includes a spacer to occupy the empty space left between the cross member and the vehicle bumper skin. This spacer, located just behind the bumper skin, is unique to each vehicle model and can therefore accurately match its curvature. The space is configured to work in a compressed state during a collision, so that it quickly reaches the force limit, above which the pedestrian's leg turns.

さらにスペーサには、例えば衝突時にエネルギーを吸収できるようにするため、肋材を設けてよい。   Further, the spacer may be provided with a brazing material so that energy can be absorbed at the time of collision, for example.

整合部分は任意に、バンパー強化材、底部スポイラー、または車両の空気吸入グリルと一体的に作られる。   The alignment portion is optionally made integral with a bumper reinforcement, bottom spoiler, or vehicle air intake grille.

ある特定の実施形態においてクロスメンバーは、車両の構造物と見当が合う区域の近辺でより硬い。よってこれらの区域は十分に強くて壊れず、衝突時にはサイドメンバーへ力を伝える。   In certain embodiments, the cross member is stiffer near an area that is in register with the vehicle structure. So these areas are strong enough not to break and transmit force to the side members in the event of a collision.

さらにスペーサの肋材は、サイドメンバーと見当が合う領域で密度を下げてよい。よってスペーサはこれらの区域でさほど硬直でなくなるから、この場所でクロスメンバーの余分な硬直さを補償する。   Furthermore, the density of the ribs of the spacers may be reduced in a region where the side members are registered. Thus, the spacer is less rigid in these areas, thus compensating for the excess stiffness of the cross member at this location.

本発明の一実施形態において、車両の形状に整合するための部分は、車両の構造物へ接続する手段を含む。したがってこれらの接続手段は下部支持体ごとに異なり、下部支持体が載置される車両モデルに特有である。さらに、ある1つの組立体の各下部支持体の接続手段は車両の横断方向に異なるサイズを呈してよく、これによりある特定の組立体の2つの下部支持体を、異なる横断方向サイズを呈する2台の車両に、例えばサイドメンバー間の間隔が異なる2台の車両に、取り付けることができる。   In one embodiment of the invention, the portion for matching the shape of the vehicle includes means for connecting to the structure of the vehicle. These connecting means are therefore different for each lower support and are specific to the vehicle model on which the lower support is placed. Furthermore, the connecting means of each lower support of a certain assembly may take on different sizes in the transverse direction of the vehicle, so that the two lower supports of a particular assembly have different transverse sizes. It can be attached to one vehicle, for example, two vehicles with different intervals between the side members.

別の実施形態においては、ある1つの下部支持体から別の下部支持体にかけて接続手段を交換できる。これらの接続手段は、クロスメンバーと各車両の各サイドメンバーとの間に配置された基礎板を備える。これらの基礎板は横断方向に各車両のサイドメンバーの寸法より大きい寸法を呈してよい。よって基礎板は同一組立体のある下部支持体から別の下部支持体にかけて同じであってよいが、なお横断方向の間隔が車両ごとに異なるサイドメンバーと見当を合わせて配置できる。   In another embodiment, the connecting means can be exchanged from one lower support to another lower support. These connecting means include a base plate disposed between the cross member and each side member of each vehicle. These foundation plates may exhibit dimensions that are greater than the dimensions of the side members of each vehicle in the transverse direction. Accordingly, the base plate may be the same from one lower support to another lower support in the same assembly, but can be arranged in register with side members that have different transverse intervals for each vehicle.

接続手段は任意に2つの部分を備え、これら2つの部分の間の接触面は、概して、車両の前にて車両の縦軸に交差する垂線を有する垂直面である。換言すると、下部支持体に載置された接続手段は面取りされた接触面を有することで、クロスメンバーで受ける力を吸収できる。クロスメンバーは屈曲状態で働くため、サイドメンバーに伝わる力から斜め方向に作用する力が生じ、この力には2つの延長部を互いに分け隔てる傾向がある。延長部の面取りされた平面は、力を各延長部に垂直に到達させることにより、サイドメンバーに向かうエネルギーの伝達を最適化するよう構成される。   The connecting means optionally comprises two parts, and the contact surface between the two parts is generally a vertical surface with a normal that intersects the longitudinal axis of the vehicle in front of the vehicle. In other words, since the connecting means placed on the lower support has a chamfered contact surface, the force received by the cross member can be absorbed. Since the cross member works in a bent state, a force acting in an oblique direction is generated from the force transmitted to the side member, and this force tends to separate the two extensions from each other. The chamfered planes of the extensions are configured to optimize the transfer of energy toward the side members by causing a force to reach each extension perpendicularly.

クロスメンバー、接続手段、または整合部分は任意に、充填ポリアミド、充填ポリプロピレン、熱硬化性材料、ハイブリッド熱可塑性複合(HTPC)材料、または供給業者Vetrotexによって販売されているTwintex繊維等の繊維によって強化された強化プラスチック材料から作られ、場合によってはスチールまたはアルミニウム板の挿入物をこれに組み合わせて作られる。   The cross member, connecting means, or alignment portion is optionally reinforced with fibers such as filled polyamide, filled polypropylene, thermoset materials, hybrid thermoplastic composite (HTPC) materials, or Twintex fibers sold by the supplier Vetrotex. Made of reinforced plastic material, and in some cases combined with steel or aluminum plate inserts.

加えて、整合部分または接続手段は、クロスメンバー上にオーバーモールドされてよい。   In addition, the alignment portion or connecting means may be overmolded on the cross member.

本発明はまた、上で説明した組立体の一部を形成する下部支持体を各々含む、2つの自動車前部ユニットからなる組立体を提供し、ここで各前部ユニットの2つのサイドメンバー間の間隔は異なる。   The present invention also provides an assembly consisting of two automotive front units, each including a lower support that forms part of the assembly described above, wherein two front members between each front unit The intervals are different.

最後に、本発明は上で説明した組立体の一部を形成する下部支持体を各々含む、2つの自動車前部ユニットからなる組立体を提供し、ここで各サイドメンバーと各車両のバンパースキンとの間の間隔は異なる。   Finally, the present invention provides an assembly of two automotive front units, each including a lower support that forms part of the assembly described above, wherein each side member and each vehicle bumper skin. The interval between is different.

本発明は、単なる例示として付され図面を参照しながら果たされる、以下の説明を読むことにより、よりよく理解できる。   The invention can be better understood by reading the following description, given by way of example only and made with reference to the drawings, in which:

本発明の組立体の一部を形成する自動車用下部支持体は、図1に示すメンバー等、クロスメンバー10を備える。このクロスメンバー10は、これが屈曲状態で働くことを可能とする材料で作られた湾曲梁である。梁10を作るのに適した材料は、充填ポリアミド、タルクまたはグラスファイバーが充填されたポリプロピレン、熱硬化性材料、商標Twintexのもとで製造されるものに類似する材料、ハイブリッド熱可塑性複合(HTPC)材料であり、場合によっては例えばアルミニウム板であるより硬い挿入物をこれに組み合わせて作られる。   The automobile lower support that forms part of the assembly of the present invention comprises a cross member 10 such as the member shown in FIG. The cross member 10 is a curved beam made of a material that allows it to work in a bent state. Suitable materials for making the beam 10 include filled polyamide, polypropylene filled with talc or glass fiber, thermoset materials, materials similar to those produced under the trademark Twintex, hybrid thermoplastic composites (HTPC). ) Material, and in some cases a harder insert, for example an aluminum plate, is combined with this.

クロスメンバー10は、これを強化するため肋材を含む。一連の肋材は、稠密にひだをなす区域12とひだがさほど稠密でない区域14とを含み、密度に大なり小なりの差があることが分かる。この肋材密度のばらつきは、梁が屈曲状態で働くときに、これが車両のサイドメンバーと見当が合う区域、すなわち区域12のあたりで高度な剛性を呈することで、極端に大きくない屈曲を保証するように構成される。   The cross member 10 includes a saddle material to reinforce this. It can be seen that the series of brazing includes a densely pleated area 12 and a less dense area 14 with a greater or lesser difference in density. This variation in the density of the brazing material ensures a bend that is not extremely large when the beam works in a bent state, as it exhibits a high degree of rigidity around the area where it is in register with the side member of the vehicle, i.e. the area 12. Configured as follows.

図1に示す下部支持体梁10は、本発明の組立体の一部を形成する別の下部支持体(図示せず)の梁と交換できる。より明確に言えば、それは全く同じである。   The lower support beam 10 shown in FIG. 1 can be replaced with a beam of another lower support (not shown) that forms part of the assembly of the present invention. More specifically, it is exactly the same.

下部支持体はさらに、車両の特有の形状へ下部支持体を整合させる整合部分を構成するスペーサ16を備え、よってこれは本発明の組立体の別の下部支持体のスペーサとは異なる。スペーサ16は、梁10の前に加えられ、梁10と車両のバンパーシールドとの間に位置する空間を占めることで、シールドの湾曲形状に可能な限り細密に整合する、さらなる下部支持体要素を構成する。   The lower support further comprises a spacer 16 that constitutes an alignment portion that aligns the lower support to the specific shape of the vehicle, and thus is different from the spacers of other lower supports of the assembly of the present invention. The spacer 16 is added in front of the beam 10 and occupies a space located between the beam 10 and the bumper shield of the vehicle, thereby providing a further lower support element that matches the curved shape of the shield as closely as possible. Constitute.

スペーサ16は、下部支持体の剛性を増すため肋材を有する。スペーサ16の特定の区域18はより低い密度にて肋材を呈する。これらの区域は、車両のサイドメンバーに見当が合うところに位置する。   The spacer 16 has a saddle member to increase the rigidity of the lower support. Certain areas 18 of the spacer 16 exhibit a brazing material at a lower density. These areas are located in register with the side members of the vehicle.

より低密度にて肋材を有する区域18は、サイドメンバーと見当が合うところで梁10の柔軟性の欠如を補償する働きをする。総じて、スペーサ16は屈曲状態ではなくむしろ圧縮状態で働き、これはスペーサ16が車両のサイドメンバーと見当が合うところで大きい剛性を呈する必要がないことを意味する。   The area 18 having the brazing material at a lower density serves to compensate for the lack of flexibility of the beam 10 in register with the side members. Overall, the spacer 16 works in a compressed state rather than in a bent state, which means that the spacer 16 need not exhibit great rigidity where it is in register with the vehicle side member.

よって図1の下部支持体は、スペーサ16によって、標準のクロスメンバー10を備えつつ、なお異なるシールドを呈する車両に載置するのに適する。異なるモデルの多様な寸法を補償するため、スペーサ16は縦及び横断方向X及びYに、より大きくまたはより小さくてよい。   Thus, the lower support of FIG. 1 is suitable for mounting on a vehicle with a standard cross member 10 but still having a different shield, by means of spacers 16. In order to compensate for the various dimensions of different models, the spacer 16 may be larger or smaller in the longitudinal and transverse directions X and Y.

最後に、図1の下部支持体は、車両のサイドメンバー(図示せず)と見当が合う梁10のところに配置された基礎板20を備える、車両の構造物へ接続するための接続手段と、衝撃吸収器22とを含む。この実施形態における接続手段は、同一組立体の別の下部支持体の接続手段と同じである。   Finally, the lower support of FIG. 1 comprises a connecting means for connecting to a vehicle structure comprising a base plate 20 arranged at a beam 10 in registration with a side member (not shown) of the vehicle. And shock absorber 22. The connection means in this embodiment is the same as the connection means of another lower support of the same assembly.

しかしながら別の実施形態においては、同一組立体の下部支持体ごとに異なる位置に基礎板20を位置付けることもできる。   However, in another embodiment, the base plate 20 can be positioned at a different position for each lower support of the same assembly.

図2に見られるとおり、本発明の別の実施形態で組立体の一部を形成する下部支持体は、図1のものと類似する梁24と、スペーサ26と、衝撃吸収器28とを備える。   As seen in FIG. 2, the lower support that forms part of the assembly in another embodiment of the invention comprises a beam 24 similar to that of FIG. 1, a spacer 26, and a shock absorber 28. .

衝撃吸収器28に加えて、この実施形態で車両のサイドメンバーへクロスメンバー24を接続する接続手段は、プラスチック材料のステップ30を備える。ステップ30は、吸収器28の受け面として各々機能することが可能な3つのハウジング32、34、及び36を含む。所与の組立体において、これらのステップ30は全下部支持体で同じである。しかしながら、吸収器28のための受け面を提供するために使われるハウジングは、所与の組立体の中で下部支持体ごとに変わってよい。よって小型車両に載置される下部支持体の場合に受け面として働くのはハウジング36であり、他方下部サイドメンバー間の間隔がより広いより大きい部類の車両の場合に、受け面を提供するために用いるのはハウジング32または34である。   In addition to the shock absorber 28, the connecting means for connecting the cross member 24 to the side member of the vehicle in this embodiment comprises a step 30 of plastic material. Step 30 includes three housings 32, 34, and 36 that can each function as a receiving surface for absorber 28. In a given assembly, these steps 30 are the same for all lower supports. However, the housing used to provide the receiving surface for the absorber 28 may vary from one lower support to another in a given assembly. Thus, it is the housing 36 that acts as a receiving surface in the case of a lower support mounted on a small vehicle, while providing a receiving surface in the case of a larger class of vehicles with wider spaces between lower side members. The housing 32 or 34 is used.

図3の実施形態では図1及び図2のものに類似する梁40が、これに沿って配置された延長部42とともに見られる。この図の下部支持体は、図示されていない、スペーサ16に類似する、スペーサを含む。   In the embodiment of FIG. 3, a beam 40 similar to that of FIGS. 1 and 2 is seen with an extension 42 disposed along it. The lower support in this figure includes a spacer, not shown, similar to the spacer 16.

延長部42は、吸収器46を設けた車両のサイドメンバー44と見当が合うところに配置される。吸収器46と見当が合うところに置かれる延長部42の内面48は、横断方向YにサイズLの基礎板を構成し、サイズLは、同じ方向でサイドメンバー44の、またはこれの吸収器46のサイズlより大きい。   The extension part 42 is disposed at a position where it is in register with the side member 44 of the vehicle provided with the absorber 46. The inner surface 48 of the extension 42, which is positioned in register with the absorber 46, constitutes a base plate of size L in the transverse direction Y, the size L of the side member 44 or of the absorber 46 in this direction. Larger than size l.

図に見られるとおり、2つのサイドメンバー間の距離がより小さい、異なるモデルの車両に下部支持体が載置される場合に、基礎板48は、別のサイドメンバー44’及び別の吸収器46’と見当を合わせるにあたって十分に幅広い。   As seen in the figure, when the lower support is placed on a different model of vehicle with a smaller distance between the two side members, the base plate 48 is separated from another side member 44 'and another absorber 46. Wide enough to align with '.

図では、基礎板48と吸収器46とが、長手方向Xに対し正確に垂直でなく、車両の内側に向かって僅かに傾く平面にて接合する様子が見てとれ、車両のサイドメンバーに対する衝突時に受ける力を可能な限り良好に伝達できる。   In the figure, it can be seen that the base plate 48 and the absorber 46 are joined in a plane that is not exactly perpendicular to the longitudinal direction X but is slightly inclined toward the inside of the vehicle. The force that is sometimes received can be transmitted as well as possible.

実際、梁40は衝突時に、一般的にはこれの中央で、すなわち2つのサイドメンバーの間に位置するこれの部分で、相当な力を受ける。この力の作用で梁40はエネルギーの一部を吸収しながら曲がり、残余を力Fの形で延長部42へ伝達する。図に見られるとおり、この力の方向は進行方向Xと同じではなく、梁40の屈曲のため僅かに斜行する。延長部42の基礎板48は傾斜しているから、力Fは基礎板48に対し概ね垂直である。よって力は吸収器46の表面に垂直に到達し、したがって吸収器46はこの力を最適な仕様で受け取る。よって吸収器は、高速度での衝突のエネルギーを可能な限り多く吸収するべく設計されるが、より大きいエネルギーの場合に、吸収器はサイドメンバーにかかる長手方向以外の力を極小化する。   In fact, the beam 40 is subjected to a considerable force upon impact, generally in the middle of it, i.e. in this part located between the two side members. Due to the action of the force, the beam 40 bends while absorbing a part of the energy, and transmits the remainder to the extension 42 in the form of a force F. As seen in the figure, the direction of this force is not the same as the direction of travel X and is slightly skewed due to the bending of the beam 40. Since the base plate 48 of the extension 42 is inclined, the force F is substantially perpendicular to the base plate 48. Thus, the force reaches perpendicular to the surface of the absorber 46, and therefore the absorber 46 receives this force with optimal specifications. Thus, the absorber is designed to absorb as much of the energy of the collision at high speed as possible, but at higher energies, the absorber minimizes non-longitudinal forces on the side members.

数ある本発明の利点のうち、クロスメンバーと整合部分とは、各々果たすべき機能に構成された非常に異なる材料で作ることができる点に注目されたい。クロスメンバーは屈曲状態で働くように構成された材料で作ることができ、他方スペーサは、歩行者の脚に対する衝突時に比較的低い抵抗レベルを速やかに提供する材料で作ることができる。   It should be noted that among the many advantages of the present invention, the cross member and the alignment portion can be made of very different materials that are each configured for the function to be performed. The cross member can be made of a material that is configured to work in a bent state, while the spacer can be made of a material that quickly provides a relatively low resistance level upon impact against a pedestrian's leg.

本発明のもうひとつの利点として、本発明の組立体の下部支持体は、形状の異なりうる車両向けに規格化されるため、比較的コンパクトである。その結果、大きい空気吸入口を有し、下部支持体のための余地が小さい車両で、それらを載置することは特に有利である。   Another advantage of the present invention is that the lower support of the assembly of the present invention is relatively compact because it is standardized for vehicles that may vary in shape. As a result, it is particularly advantageous to mount them in a vehicle having a large air inlet and a small room for the lower support.

最後に、本発明が上で説明した実施形態に限定されないことに注目されたい。   Finally, it should be noted that the present invention is not limited to the embodiments described above.

本発明の第1の実施形態で組立体の一部を形成する下部支持体の斜視図である。It is a perspective view of the lower support body which forms a part of assembly in the 1st embodiment of the present invention. 本発明の第2の実施形態で組立体の一部を形成する下部支持体の斜視図である。It is a perspective view of the lower support body which forms a part of assembly in the 2nd embodiment of the present invention. 本発明の第3の実施形態で組立体の一部を形成する下部支持体の一部分の平面図である。It is a top view of a part of lower support which forms a part of assembly in the 3rd embodiment of the present invention.
