Description

Die Erfindung betrifft ein Kopfbauteil zum Anbringen an der Stirnseite eines Fahrzeugs mit einer Tragstruktur, die Anschlussmittel zur mechanischen Befestigung an dem Fahrzeug aufweist, und mit wenigstens einem Energieverzehrelement zum Abbau von kinetischer Energie im Falle eines Aufpralls auf ein Hindernis, das so ausgebildet ist, dass die kinetische Energie bei fortschreitender Verformung kontinuierlich abgebaut wird, wobei wenigstens ein Energieverzehrelement Teil der Tragstruktur ist.The invention relates to a head component for attachment to the front of a vehicle having a support structure, which has connection means for mechanical attachment to the vehicle, and with at least one energy dissipation element for reducing kinetic energy in the event of an impact on an obstacle, which is designed such that the kinetic energy is continuously reduced as the deformation proceeds, at least one energy dissipation element being part of the support structure.

Ein solches Kopfbauteil ist aus der EP 0 802 100 A1 bereits bekannt. Das dort offenbarte Kopfbauteil ist mit Anschlussmitteln zur Montage an ein Schienenfahrzeug ausgerüstet und weist einen sich zu einer möglichen Fahrtrichtung quer und horizontal erstreckenden nicht deformierbaren Rammträger auf. Ferner sind Energieverzehrelemente in Form welliger Bleche vorgesehen, die im hinteren Bereich des Kopfbauteils angeordnet sind.Such a head component is from the EP 0 802 100 A1 already known. The head component disclosed therein is equipped with connection means for mounting on a rail vehicle and has a non-deformable Rammträger extending transversely and horizontally to a possible direction of travel. Furthermore, energy-absorbing elements in the form of corrugated metal sheets are provided, which are arranged in the rear region of the head component.

Die EP 1 394 009 B2 offenbart ein Schienenfahrzeug, an dessen beidseitigen Stirnseiten jeweils Kopfbauteile vorgesehen sind. Die fest montierten Kopfbauteile weisen in ihrem Bondenbereich angeordnete Energieverzehrelemente auf.The EP 1 394 009 B2 discloses a rail vehicle, on the two-sided end faces each head components are provided. The permanently mounted head components have energy dissipation elements arranged in their bonding area.

Die EP 1 223 095 offenbart eine Tragstruktur für ein Kopfbauteil eines Schienenfahrzeugs, in der Energieverzehrelemente eingebaut sind.The EP 1 223 095 discloses a supporting structure for a head component of a rail vehicle, in which energy absorbing elements are installed.

Weitere Kopfbauteile sind aus der EP 1 215 098 A sowie aus der WO 2006/042348 A bekannt geworden.Further head components are from the EP 1 215 098 A as well as from the WO 2006/042348 A known.

Aus der DE 102 54 440 A1 ist ein Kopfbauteil zur Montage an den Wagenkasten eines Schienenfahrzeugs bekannt, das den stirnseitigen Fahrzeugkopf des Schienenfahrzeugs ausbildet, in dem sich der Führerstand befindet. Um den jeweils vorliegenden Normerfordernissen im Falle einer Kollision mit einem Hindernis gerecht zu werden, ist in dem Kopfbauteil unterhalb des Fahrgastraumes ein teleskopartiger separater Stoßaufnehmer angeordnet. Der separate Stoßaufnehmer weist eine reversible Stufe auf, bei der ein Puffer unter Spannung einer Pufferfeder in ein Aufnahmerohr hinein verschbiebbar ist. Erst bei größeren Aufprallkräften kommt es zum irreversiblen Verformen des Aufnahmerohrs und somit zum Energieverzehr. Durch die Verformung des Aufnahmerohrs wird der Abbau der kinetischen Energie fortgesetzt, so dass das Aufnahmerohr auch als irreversible Stufe des Stoßaufnehmers oder als Energieverzehrelement bezeichnet ist. Ein separates Energieverzehrelement ist jedoch kostenintensiv und raumgreifend.From the DE 102 54 440 A1 a head component for mounting to the car body of a rail vehicle is known, which forms the front-side vehicle head of the rail vehicle in which the driver's cab is located. In order to meet the respective existing standard requirements in the event of a collision with an obstacle, a telescopic, separate shock absorber is arranged in the head component below the passenger compartment. The separate shock absorber has a reversible stage in which a buffer under a tension of a buffer spring in a receiving tube is verschiebiebbar. Only with larger impact forces it comes to the irreversible deformation of the receiving tube and thus to the energy consumption. The deformation of the receiving tube of the degradation of the kinetic energy is continued, so that the receiving tube is also referred to as irreversible stage of the shock absorber or as an energy dissipation element. However, a separate energy dissipation element is cost-intensive and expansive.

Aus der DE 10 2004 028 964 A1 ist ein Fahrzeug bekannt geworden, dessen Wagenkastenstruktur im Bereich von Deformationszonen gezielt verformt werden kann. Dabei sind.die Deformationszonen so angeordnet, dass nach der Deformation ausreichend Platz für die Person im Fahrzeug verbleibt. Die Deformationszonen dienen somit der Sicherheit des jeweiligen Fahrzeugsführers.From the DE 10 2004 028 964 A1 has become known a vehicle whose body structure can be selectively deformed in the region of deformation zones. The deformation zones are arranged in such a way that sufficient space remains for the person in the vehicle after the deformation. The deformation zones thus serve the safety of the respective driver.

Ein separates und damit selbsttragendes Kopfbauteil ist in der DE 195 28 035 A1 beschrieben. Das dort offenbarte Kopfbauteil wird an einen schienengeführten Triebwagen oder mit anderen Worten an eine Lokomotive montiert. Das separate Kopfbauteil weist jedoch keine Energieverzehrelemente auf.A separate and thus self-supporting head component is in the DE 195 28 035 A1 described. The head component disclosed there is mounted on a rail-powered railcar or in other words on a locomotive. However, the separate head component has no energy dissipation elements.

Die DE 198 09 489 A1 und die DE 196 35 221 C1 beschreiben jeweils separat an Schienenfahrzeuge anbringbare Aufprallschutzvorrichtungen für Schienenfahrzeuge, die am Schienenfahrzeug befestigbare Kollisionspuffer ausbilden.The DE 198 09 489 A1 and the DE 196 35 221 C1 each describe separately attachable to rail vehicles impact protection devices for rail vehicles which form collision buffers which can be fastened to the rail vehicle.

Aufgabe der Erfindung ist es, ein separat montierbares Kopfbauteil der eingangs genannten Art bereitzustellen, das kostengünstig ist und den üblichen Sicherheitserfordernissen gerecht wird, wobei gleichzeitig ein zusätzlicher Stauraum zur Aufnahme von weiteren Fahrzeugkomponenten bereitgestellt ist.The object of the invention is to provide a separately mountable head component of the type mentioned, which is inexpensive and meets the usual safety requirements, at the same time an additional storage space for receiving additional vehicle components is provided.

Die Erfindung löst diese Aufgabe dadurch, dass ein Rammträger der Tragstruktur, der sich an der von den Anschlussmitteln abgewandten Seite der Tragstruktur in einer Querrichtung erstreckt, Teil eines Energieverzehrelementes ist und das Energieverzehrelement einen im Vergleich zum Rammträger schwerer deformierbaren Querträger aufweist, der von dem Rammträger zu den Anschlussmitteln hin versetzt angeordnet ist und sich in Querrichtung erstreckt, wobei sich zwischen dem Rammträger und dem Querträger ein durch den Aufprall verformbares Material erstreckt.The invention solves this problem in that a Rammträger the support structure which extends on the side facing away from the connection means of the support structure in a transverse direction, is part of an energy absorbing element and the energy absorbing element has a heavier deformable compared to Rammträger cross member, of the Rammträger is arranged offset to the connection means and extends in the transverse direction, wherein extending a deformable by the impact material between the Rammträger and the cross member.

Erfindungsgemäß ist ein separates Kopfbauteils bereitgestellt, das wie bereits aus dem Stand der Technik bekannt, auf einfache Art und Weise über die Anschlussmittel beispielsweise mit dem Wagenkasten eines Schienenfahrzeugs verbindbar ist. Nach der Montage an den Wagenkasten bildet das Kopfbauteil die Stirnseite und damit den Kopf oder mit anderen Worten die Frontseite des Fahrzeuges aus. Um bei einem Aufprall auf ein Hindernis, das sich beispielsweise auf dem Fahrweg befindet, die kinetische Energie des Fahrzeugs gezielt abzubauen und in Verformungsenergie umzuwandeln, verfügt das erfindungsgemäße Kopfbauteil über Energieverzehrelemente, die Teil der Tragstruktur des Kopfbauteils sind. Die Energieverzehrelemente sind somit mit anderen Worten in die Tragstruktur des Kopfbauteils integriert. Raumgreifende separate Energieverzehrelemente im Innern des Kopfbauteils sind somit durch die erfindungsgemäße Ausgestaltung der Tragstruktur in ihrer Wirkung ersetzt mit einem Raumgewinn im Gefolge. Selbstverständlich ist es im Rahmen der Erfindung möglich, das Kopfbauteil mit zusätzlichen Energieverzehrelementen und Puffern auszurüsten. Deren Fähigkeit zum Abbau kinetischer Energie wird dann durch die Erfindung unterstützt. Die Energieverzehrelemente der Tragstruktur sind so ausgestaltet, dass bei den üblichen Aufprallunfällen die kinetische Energie in der Regel von den integrierten Energieverzehrelementen und gegebenenfalls von an dem Kopfbauteil montierten und gegebenenfalls Deformationsbereiche aufweisenden Puffern vollständig aufgenommen wird. Im Rahmen der Erfindung kann das Kopfbauteil daher nach dem Aufprall auf einfache Art und Weise durch ein neues Kopfbauteil ersetzt werden, so dass die Folgen eines Unfalls begrenzt sind und schnell behoben werden können. Darüber hinaus stellt das erfindungsgemäße Kopfbauteil einen großen Innenraum aufgrund der fehlenden separaten Energieverzehrelemente bereit. Schließlich ist die Integration der Energieverzehrelemente in die Tragstruktur kostengünstiger als die Verwendung separater Energieverzehrelemente.According to the invention, a separate head component is provided which, as already known from the prior art, can be connected in a simple manner via the connection means, for example to the car body of a rail vehicle. After assembly to the car body, the head component forms the front side and thus the head or in other words the front of the vehicle. In order to specifically reduce the kinetic energy of the vehicle in an impact on an obstacle, which is located for example on the track and convert it into deformation energy, the head component according to the invention has energy absorbing elements that are part of the support structure of the head component. The energy dissipation elements are thus integrated in other words in the support structure of the head component. Spatial, separate energy-absorbing elements inside the head component are thus replaced by the inventive design of the support structure in their effect with a gain in space in the wake. Of course, it is possible within the scope of the invention to equip the head component with additional energy-absorbing elements and buffers. Their ability to dissipate kinetic energy is then supported by the invention. The energy dissipation elements of the support structure are designed so that in the usual impact accidents, the kinetic energy is usually completely absorbed by the integrated energy dissipation elements and optionally mounted on the head component and optionally deformation areas having buffers. In the context of the invention, the head component can therefore be replaced after the impact in a simple manner by a new head component, so that the consequences of an accident are limited and can be remedied quickly. In addition, the head component according to the invention provides a large interior due to the lack of separate energy-absorbing elements. Finally, the integration of the energy dissipation elements into the support structure is more cost-effective than the use of separate energy dissipation elements.

Erfindungsgemäß ist ein Rammträger der Tragstruktur, der sich an der von den Anschlussmitteln abgewandten Seite der Tragstruktur in einer Querrichtung erstreckt, Teil eines Energieverzehrelementes. Mit Querrichtung ist in diesem Fall eine Richtung rechtwinklig zur Fahrtrichtung des Fahrzeugs gemeint, wobei sich jeder Rammträger und auch die hier nachfolgend eingeführten Querträger sich jeweils in einer Ebene erstrecken, die im Wesentlichen parallel zum Fahrweg verläuft. Rammträger sind als solche im Bereich der Bahntechnik bereits bekannt und verlaufen unmittelbar an der Stirnseite des Fahrzeugs beziehungsweise Kopfbauteils. Sie sind bei einem Aufprall somit dem jeweiligen Hindernis unmittelbar zugewandt. Gemäß dieser vorteilhaften Weiterentwicklung der Erfindung setzt die Wirkung der Energieverzehrelemente daher unmittelbar mit Erfassen des Hindernisses ein.According to the invention, a ram support of the support structure, which extends in a transverse direction on the side of the support structure facing away from the connection means, forms part of an energy dissipation element. With transverse direction is meant in this case, a direction perpendicular to the direction of travel of the vehicle, each Rammträger and also introduced here below cross members each extending in a plane which is substantially parallel to the track. Rammträger are already known as such in the field of railway technology and run directly on the front side of the vehicle or head component. In an impact, they are thus directly facing the respective obstacle. According to this advantageous development of the invention, the effect of the energy dissipation elements therefore begins immediately with the detection of the obstacle.

Das Energieverzehrelement weist ferner einen im Vergleich zum Rammträger schwer deformierbaren Querträger auf, der von dem Rammträger zu den Anschlussmitteln hin versetzt angeordnet ist und sich in Querrichtung erstreckt, wobei sich zwischen dem Rammträger und dem Querträger ein durch den Aufprall verformbares Material angeordnet ist. Gemäß dieser vorteilhaften Weiterentwicklung wird im Falle eines Aufpralls zunächst der Rammträger auf die Anschlussmittel und somit auf den Querträger zu bewegt. Dabei setzt eine fortschreitende Verformung des verformbaren Materials ein, bis dessen Verformbarkeit erschöpft ist. Durch den im Vergleich zum Rammträger beziehungsweise dem verformbaren Material mechanisch festeren Querträger wird die Verformung der Tragstruktur beziehungsweise des Energieverzehrelementes gezielt auf dessen Stirnseite begrenzt. Erst bei größeren Aufprallkräften in Folge höherer Geschwindigkeiten des Fahrzeugs kommt es zum Verformen des Querträgers.The energy dissipation element furthermore has a cross member, which is difficult to deform in comparison to the ram carrier, which is offset from the ram carrier to the connection means and extends in the transverse direction, wherein a material deformable by the impact is arranged between the ram support and the cross member. According to this advantageous further development, in the event of an impact the ram carrier is first moved towards the connection means and thus to the cross member. In this case, a progressive deformation of the deformable material begins until its deformability is exhausted. As a result of the cross member, which is mechanically stronger in comparison to the ram carrier or the deformable material, the deformation of the support structure or of the energy dissipation element is specifically limited to its end face. Only with larger impact forces as a result of higher speeds of the vehicle it comes to deformation of the cross member.

Gemäß einer bevorzugten Weiterentwicklung weist das verformbare Material Triggerstellen auf. Solche Triggerstellen, die auch als Sollverformstellen bezeichnet werden können, sind Abschnitte oder Bereiche des verformbaren Materials, die so ausgestaltet sind, dass eine Deformation des verformbaren Materials in diesen Bereichen oder mit anderen Worten an diesen Stellen beginnt. Beispiele für Triggerstellen sind Bereiche mit gegenüber den angrenzenden Bereichen herabgesetzter mechanischer Festigkeit oder sich entgegen der Stoßrichtung verjungende Bereiche oder Abschnitte.According to a preferred development, the deformable material has trigger points. Such trigger points, which can also be referred to as desired deformation points, are sections or regions of the deformable material which are designed such that a deformation of the deformable material in these areas or in other words starts at these sites. Examples of trigger points are regions with reduced mechanical strength relative to the adjacent regions or regions or sections which deflect against the impact direction.

Zweckmäßigerweise sind Querträger und Rammträger über sich beidseitig von Quer- und Rammträger erstreckende Längsträger miteinander verbunden, wobei die Längsträger Schwachstellen zur mechanischen Schwächung der Materialfestigkeit aufweisen. Zweckmäßigerweise ist das freie Ende jedes Bogenabschnittes fest mit dem Rammträger verbunden. Im Falle eines Aufpralls werden aufgrund der Schwächung des Materials Triggerstellen gebildet, an denen der Deformationsprozess beginnt. Durch die Schwachstellen wird daher eine gezielte Deformation ermöglicht.Conveniently, cross member and Rammträger are connected to each other on both sides of transverse and Rammträger extending side members together, the side members have weak points for mechanical weakening of the material strength. Conveniently, the free end of each arc section is firmly connected to the Rammträger. In the event of an impact, due to the weakening of the material, trigger points are formed where the deformation process begins. Due to the weak points, therefore, a targeted deformation is possible.

Zweckmäßigerweise überragen die Längsträger den Rammträger in einer von den Anschlussmitteln abgewandten Richtung. Gemäß dieser vorteilhaften Weiterentwicklung gerät somit der Längsträger im Falle eines Aufprallunfalls zuerst in Kontakt mit dem Hindernis, wobei es zu einer gezielten Verformung des Längsträgers und somit des gesamten Energieverzehrelementes kommt. Darüber hinaus wird der gleichmäßige Abbau der kinetischen Energie bei fortschreitender Verformung durch diese bauliche Maßnahme verbessert.Conveniently, the longitudinal members project beyond the Rammträger in a direction away from the connection means direction. In accordance with this advantageous further development, the longitudinal member thus first comes into contact with the obstacle in the event of an impact accident, resulting in a targeted deformation of the longitudinal member and thus of the entire energy dissipation element. In addition, the uniform degradation of the kinetic energy as the deformation progresses is improved by this structural measure.

Vorteilhafterweise bildet das verformbare Material wenigstens eines Energieverzehrelementes eine Wellenstruktur aus. Durch die Wellenstruktur erhöht sich das Maß an kinetischer Energie, das durch das Energieverzehrelement abgebaut werden kann. Die Wellenstruktur sorgt grundsätzlich schon auf Grund ihrer Gestalt oder Form für einen im Vergleich zu ebenen Blechen erhöhten Energieverzehr. Hinzu tritt, dass durch die Wellenstruktur die Masse des verformbaren Materials bei gleich bleibender Raumbeanspruchung erhöht wird. Durch der wellenartige geometrische Ausgestaltung und die erhöhte Masse kann bei der Verformung des Materials mehr kinetische Energie abgebaut werden als durch ein beispielsweise flaches verformbares Material ohne aufragende Bereiche.Advantageously, the deformable material of at least one energy dissipation element forms a wave structure. The wave structure increases the amount of kinetic energy that can be dissipated by the energy dissipation element. Basically, the wave structure, because of its shape or form, already ensures an increased energy consumption compared to flat sheets. Add to that by the Wave structure, the mass of deformable material is increased with constant space stress. Due to the wave-like geometric design and the increased mass, more kinetic energy can be dissipated during the deformation of the material than, for example, by a flat deformable material without protruding areas.

Gemäß einer diesbezüglichen Weiterentwicklung weist die Wellenstruktur sich rechtwinklig zum zugeordneten Rammträger erstreckende erhabene Wellenabschnitte auf. Durch die besagte Ausrichtung der Wellenabschnitte wird die bei der Verformung abgebaute Energie noch weiter erhöht.According to a related development, the wave structure has at a right angle to the associated Rammträger extending raised shaft sections. The said alignment of the shaft sections further increases the energy dissipated during the deformation.

Zweckmäßigerweise sind die Wellenabschnitte an ihrer dem Rammträger zugewandten Seite verjüngt ausgebildet. Dabei ist es weiterhin zweckmäßig, wenn die verjüngt ausgebildeten Seiten oder Enden der Wellenabschnitte direkt mit dem Rammträger verbunden sind. Durch die Verjüngung ist das verformbare Material unter Ausbildung von so genannten Triggerstellen "getriggert". Die Triggerstellen bilden Sollverformstellen aus, an denen allein aufgrund der Materialausgestaltung das Verformen des Energieverzehrelementes beginnt.Conveniently, the shaft sections are tapered on their side facing the Rammträger. It is also expedient if the tapered sides or ends of the shaft sections are connected directly to the Rammträger. By rejuvenation the deformable material is "triggered" to form so-called trigger points. The trigger points form desired deformation points at which the deformation of the energy dissipation element begins, solely on account of the material design.

Gemäß einer bevorzugten Ausgestaltung bilden die Wellenabschnitte Pyramidenstümpfe aus, wobei die Höhe der Pyramidenstümpfe an ihren dem Rammträger zugewandten Ende abnimmt.According to a preferred embodiment, the shaft portions form truncated pyramids, the height of the truncated pyramids decreasing at their end facing the ram support.

Gemäß einer diesbezüglich abweichenden Ausgestaltung der Erfindung ist das verformbare Material durch wenigstens ein sich zwischen Rammträger und Querträger erstreckendes Verformblech realisiert. Gemäß einer bevorzugten Ausgestaltung sind zwei parallele Verformbleche zwischen Querträger und Rammträger vorgesehen. Das oder die Verformbleche sind beispielsweise eben ausgestaltet.According to a deviating in this respect embodiment of the invention, the deformable material is realized by at least one extending between Rammträger and cross member Verformblech. According to a preferred embodiment, two parallel Verformbleche between cross member and Rammträger provided. The one or more Verformbleche are configured, for example, just.

Zweckmäßigerweise ist das Energieverzehrelement Teil eines Bodenabschnittes der Tragstruktur.Conveniently, the energy dissipation element is part of a bottom portion of the support structure.

Gemäß einer hiervon abweichenden Ausgestaltung erstreckt sich das Energieverzehrelement unterhalb von Fensterausnehmungen der Tragstruktur, die zur Aufnahme einer transparenten Frontscheibe vorgesehen sind. Gemäß der beiden genannten Ausgestaltungen des Energieverzehrelements erstreckt sich das Energieverzehrelement im Wesentlichen parallel zum Fahrweg und quer zur Fahrtrichtung.According to a different embodiment, the energy absorbing element extends below window recesses of the support structure, which are provided for receiving a transparent windshield. According to the two aforementioned embodiments of the energy-absorbing element, the energy-absorbing element extends substantially parallel to the travel path and transversely to the direction of travel.

Gemäß einer bevorzugten Ausgestaltung ist jedes Energieverzehrelement Teil der Tragstruktur.According to a preferred embodiment, each energy dissipation element is part of the support structure.

FIG. 1 shows an embodiment of the head component 1 according to the invention in a perspective view. The head component 1 is in the in FIG. 1 shown realized only by a support structure 2. Other components of the head component, such as headlights, ventilation systems, driver's desk, driver's seat and the like, were figuratively not shown for reasons of clarity. For the sake of completeness, it should be pointed out that the support structure 2 headlamp recesses 3 for accommodating headlamps, windscreen recesses 4 for receiving windshields have an upper headlight mount 5 for receiving an upper headlamp and storage spaces 6 for accommodating air conditioning systems and the like.

Die Tragstruktur 2 verfügt ferner über zwei Seitenwände 7, eine Dachabdeckung 8 und eine Bodenwandung 9 sowie über eine Führertischstruktur 10 zur Anbringung eines figürlich nicht dargestellten Führertisches. Zur Montage der Tragstruktur 2 an einen Wagenkasten eines Schienenfahrzeugs sind schematisch dargestellte Anschlussmittel 11 vorgesehen, bei denen es sich in dem gezeigten Ausführungsbeispiel um einfache Flanschverbindungen handelt, die lösbar mit Flanschen des Wagenkastens verbunden werden können. Zur Verbindung dienen beispielsweise Schließringbolzen. Schließringbolzen sind einfach anbringbar und sorgen für einen hohen mechanischen Halt.The support structure 2 further has two side walls 7, a roof cover 8 and a bottom wall 9 and a guide table structure 10 for attachment of a figuratively not illustrated guide table. For mounting the support structure 2 to a car body of a rail vehicle schematically illustrated connection means 11 are provided, which is in the illustrated embodiment is simple flange, which can be releasably connected to flanges of the car body. To connect, for example, serve lockbolts. Locking bolts are easy to attach and provide a high mechanical support.

Die Tragstruktur 2 ist zweckmäßigerweise aus Stahl gefertigt.The support structure 2 is suitably made of steel.

An der von den Anschlussmitteln 11 abgewandten Seite, also an der Stirnseite der Tragstruktur 2 oder des Kopfbauteils 1, ist ein unterer Rammträger 12 vorgesehen, der sich in einer Querrichtung, also rechtwinklig zu einer Fahrtrichtung des Fahrzeugs und im Wesentlichen parallel zu einem Fahrweg, also horizontal, erstreckt. Unterhalb der Frontscheibenausnehmungen 4 erstreckt sich ein mittlerer durch ein Blech 13 verdeckter mittlerer Querträger 14. Zu den Anschlussmitteln 11 hin versetzt angeordnet ist in Figur 1 noch ein Querträger 15 erkennbar. Dieser erstreckt sich ebenfalls horizontal in Querrichtung, also parallel zum Rammträger 14. Die Rammträger 12 und 14 sowie der Querträger 15 sind jeweils Bestandteil eines Energieverzehrelementes.On the side facing away from the connection means 11 side, ie on the front side of the support structure 2 or the head component 1, a lower Rammträger 12 is provided, which is in a transverse direction, ie perpendicular to a direction of travel of the vehicle and substantially parallel to a track, ie horizontal, extends. Below the Windscreenausnehmungen 4 extends a central through a plate 13 concealed central cross member 14 to the connection means 11 offset towards is arranged in FIG. 1 still a cross member 15 recognizable. This also extends horizontally in the transverse direction, ie parallel to the Rammträger 14. The Rammträger 12 and 14 and the cross member 15 are each part of an energy absorbing element.

Figur 2 zeigt eines der Energieverzehrelemente 16 der Tragstruktur 2 genauer. Das besagte Energieverzehrelement 16 erstreckt sich unterhalb der in Figur 1 gezeigten Frontscheibenausnehmungen 4 und bildet die Führertischstruktur 10 aus. Bestandteile des Energieverzehrelementes 16 sind der sich in Querrichtung erstreckende Rammträger 14, der sich parallel dazu erstreckende Querträger 15 und zwei Längsträger 17 und 18, welche den Querträger 15 mit dem Rammträger 14 mechanisch verbinden. Dabei weist der Längsträger 17, 18 einen Bogenabschnitt 19 auf, der so gekrümmt ist, dass die beiden freien Enden der Längsträger 17, 18 einander zugewandt sind. Dabei sind die freien Enden der Längsträger 17 und 18 mit dem Rammträger 14 mechanisch verbunden, wobei der Rammträger 14 zu den Anschlussmitteln hin versetzt angeordnet ist, so dass die Seitenträger 17 und 18 den Rammträger 14 an ihren Abschnitten 20 in Fahrtrichtung überragen. FIG. 2 shows one of the energy dissipation elements 16 of the support structure 2 in more detail. Said energy dissipation element 16 extends below the in FIG. 1 shown Frontscheibenausnehmungen 4 and forms the guide table structure 10. Components of the energy dissipation element 16 are the transversely extending Rammträger 14, extending parallel thereto cross member 15 and two longitudinal members 17 and 18 which mechanically connect the cross member 15 with the Rammträger 14. In this case, the longitudinal member 17, 18 an arc portion 19 which is curved so that the two free ends of the side members 17, 18 facing each other. The free ends of the longitudinal members 17 and 18 are mechanically connected to the Rammträger 14, wherein the Rammträger 14 is arranged offset to the connection means, so that the side supports 17 and 18 project beyond the Rammträger 14 at its portions 20 in the direction of travel.

Zur mechanischen Schwächung der Bogenabschnitte 19 weisen diese jeweils eine Schwachstelle 21 in Form von einfachen Ausnehmungen auf. Aufgrund dieser Ausnehmungen 21 ist die mechanische Festigkeit der Seitenträger 17, 18 in dem Bogenabschnitt 19 herabgesetzt, so dass sich diese bevorzugt bei einem Aufprall in diesen Bereichen nach innen verformen. Zwischen dem Rammträger 14 und dem Querträger 15 ist ein verformbares Material 22 in Form von zwei parallel zueinander verlaufenden ebenen Verformblechen ausgebildet.For mechanical weakening of the bow portions 19, these each have a weak point 21 in the form of simple recesses. Due to these recesses 21, the mechanical strength of the side supports 17, 18 is reduced in the arcuate portion 19, so that they deform preferably in an impact in these areas inward. Between the Rammträger 14 and the cross member 15 is a deformable Material 22 formed in the form of two mutually parallel planar Verformblechen.

Bei einem Aufprall geraten die Abschnitte 20 in Kontakt mit dem Hindernis. Es kommt zunächst zu einer nach innen gewandten Verformung der Seitenträger 17 und 18 an ihren Bogenabschnitten 19 und erst dann zu einem Wandern des Rammträgers 14 auf den Querträger 15 zu unter Verformung der Verformbleche 22. Dabei weist der Querträger 15 eine im Vergleich zum Rammträger 14 und den Verformblechen 22 erhöhte mechanische Festigkeit auf, so dass dieser beim Aufprall eine Art Widerlager für den. Verformprozess ausbildet. Es kommt zu einem konstanten Energieverzehr und somit zu einem kontrollierten Abbau der kinetischen Energie des Fahrzeugs. Erst bei zu hohen Aufprallkräften in Folge sehr hoher Geschwindigkeiten kommt es auch zum irreversiblen Verformen des formstabilen Querträgers 15.In an impact, the sections 20 come into contact with the obstacle. It comes first to an inwardly facing deformation of the side support 17 and 18 at their bow portions 19 and only then to a migration of the Rammträgers 14 on the cross member 15 to deform the Verformbleche 22. In this case, the cross member 15 in comparison to the Rammträger 14 and the Verformblechen 22 increased mechanical strength, so that this on impact a kind of abutment for the. Forming deformation process. It comes to a constant energy consumption and thus to a controlled reduction of the kinetic energy of the vehicle. Only at too high impact forces as a result of very high speeds it comes to irreversible deformation of the dimensionally stable cross member 15th

Figur 3 zeigt ein weiteres Energieverzehrelement 23, das den Bodenabschnitt 9 der Tragstruktur 2 gemäß Figur 1 ausbildet. Das Energieverzehrelement 23 besteht aus dem Rammträger 12 sowie aus einem parallel zu dem Rammträger 12 verlaufenden Querträger 24, wobei zwischen dem Rammträger 12 und dem Querträger 24 ein verformbares Material, hier ein Verformblech 25 aus Stahl, angeordnet ist. Der Querträger 24 und der Rammträger 12 sind über Seitenträger 17 und 18 miteinander verbunden, die unter Ausbildung von Bogenabschnitten 19 aufeinander zu gekrümmt sind. Zur mechanischen Ausbildung von Schwachstellen weisen die Bogenabschnitte 19 wiederum eine Ausnehmung 21 auf. In dem Verformblech 25 ist weiterhin eine Entlüftungsöffnung 26 zum Ausblasen von Luft durch die figürlich nicht dargestellten raumlufttechnischen Anlagen vorgesehen. In Figur 3 ist weiterhin erkennbar, dass das Verformblech 25 eine Wellenstruktur mit Wellenabschnitten 27 ausbildet. Die Wellenabschnitte 27 bilden Pyramidenstümpfe aus und sind an ihrem zum Rammträger 12 hinweisenden Ende verjüngt. Dabei nimmt die Höhe der Pyramidenstümpfe in Richtung des Rammträgers 12 ab. Auf diese Weise wird die Verformbarkeit der auf den Rammträger 12 zuweisenden Enden der Pyramidenstümpfe vereinfacht. Die Pyramidenstümpfe sind daher getriggert und bilden mittels der besagten Verjüngung Triggerstellen aus. An der vom Rammträger 12 abgewandten Seite der Wellenabschnitte 27 ist hingegen eine Verstärkungsrippe 28 vorgesehen, welche die Wellenabschnitte 27 mechanisch miteinander verbindet. Die Verstärkungsrippe 28 dient lediglich Dichtzwecken. Durch die beschriebene Konfiguration des Verformbleches 25 ist ein hoher und konstanter Energieverzehr bei einem Aufprall ermöglicht. Nach einem Unfall kann das deformierte Kopfbauteil durch Aufsprengen von Schließbolzens komplett ausgetauscht werden. Deformationen am übrigen Fahrzeug sind durch die Energieverzehrelemente vermieden. FIG. 3 shows a further energy dissipation element 23, the bottom portion 9 of the support structure 2 according to FIG. 1 formed. The energy dissipation element 23 consists of the Rammträger 12 and from a parallel to the Rammträger 12 extending cross member 24, wherein between the Rammträger 12 and the cross member 24, a deformable material, here a deformable metal sheet 25 made of steel, is arranged. The cross member 24 and the Rammträger 12 are connected to one another via side support 17 and 18, which are curved towards each other to form bow sections 19. For the mechanical formation of weak points, the arc sections 19 in turn have a recess 21. In the Verformblech 25 is still a vent 26 for blowing air through the figuratively not shown room ventilation systems provided. In FIG. 3 Furthermore, it can be seen that the deformation plate 25 forms a wave structure with shaft sections 27. The shaft sections 27 form truncated pyramids and are tapered at their end facing the Rammträger 12 end. The height of the truncated pyramids decreases in the direction of the Rammträgers 12. In this way, the deformability of the facing on the Rammträger 12 ends of the truncated pyramids is simplified. The truncated pyramids are therefore triggered and form trigger points by means of said rejuvenation. On the side facing away from the Rammträger 12 side of the shaft portions 27, however, a reinforcing rib 28 is provided which connects the shaft portions 27 mechanically to each other. The reinforcing rib 28 is for sealing purposes only. The described configuration of the Verformbleches 25 a high and constant energy consumption is possible in an impact. After an accident, the deformed head component can be completely replaced by breaking the striker. Deformations on the rest of the vehicle are avoided by the energy dissipation elements.
