Abstract

In the carrier frame structure, especially for a vehicle chassis, each intersection point uses a prefabricated fibre blank (8) with three-dimensional fibre structure running through and holding pockets (10) for the profiled chassis frame sections (4). With the inserted chassis frame sections, the blank surrounds the component parts at the intersection, and a moulding tool (14) gives a compression and solidification to give an integral chassis intersection point with the frame members fixed accurately in position. The blank (8) is of reinforcement fibres using glass, carbon or aramide fibres or their mixtures, with thermoplastic fibres as a matrix.

Description

Die Erfindung bezieht sich auf einen Tragrahmen in Gerüstbauweise insbesondere für Kraftfahrzeug, nach dem Oberbegriff des Patentan­ spruchs 1.The invention relates to a support frame in scaffolding especially for motor vehicles, according to the preamble of the patent saying 1.

Kraftfahrzeugrahmen in Gerüstbauweise werden im allgemeinen aus vorge­ fertigten Metallprofilen hergestellt, die an den Knotenstellen mitein­ ander verschweißt werden. Nachteilig an einer solchen Bauart ist zum einen das - selbst bei Verwendung von Leichtmetallprofilen - immer noch hohe Eigengewicht und zum anderen die relativ niedrige Ferti­ gungsgenauigkeit, deren Ursache in dem schweißbedingten Metallverzug im Bereich der Knotenstellen liegt.Motor vehicle frames in scaffolding are generally from made metal profiles that are at the nodes other welded. A disadvantage of such a type is that always - even when using light metal profiles still high weight and secondly the relatively low ferti accuracy, the cause of which is the sweat-related metal distortion lies in the area of the nodes.

Um die überlegenen Festigkeits- und Leichtbaueigenschaften von Faser­ verbundwerkstoffen zu nutzen, ist es ferner bekannt, den Fachwerkrah­ men eines Hubschrauber-Cockpits in der Weise herzustellen, daß die einzelnen Rahmenprofilteile zunächst getrennt voneinander aus Faser­ verbundwerkstoff ausgeformt und konsolidiert und dann über formsteife, metallische Knotenstücke zum fertigen Fachwerkrahmen zusammengefügt werden. Auch bei dieser Bauweise ergeben sich jedoch unerwünscht hohe Fertigungstoleranzen, und vor allem kommt es im Anschlußbereich zwi­ schen Faserverbundprofilen und Knotenstücken zu übermäßigen örtlichen Spannungskonzentrationen, die durch aufwendige Gegenmaßnahmen, etwa örtlich eingefügte Verstärkungslagen in der Faserstruktur, abgebaut werden müssen.The superior strength and lightweight properties of fiber to use composite materials, it is also known to the Fachwerkrah of a helicopter cockpit in such a way that the individual frame profile parts initially separated from each other from fiber composite material shaped and consolidated and then over rigid, metallic knot pieces put together to the finished framework become. However, this design also results in undesirably high levels Manufacturing tolerances, and especially in the connection area between fiber composite profiles and node pieces to excessive local Stress concentrations caused by complex countermeasures, such as locally inserted reinforcement layers in the fiber structure, broken down Need to become.

Weiterhin ist aus der DE 38 26 636 C2 ein Cockpit-Rahmen in Gerüst­ bauweise bekannt, bei dem sämtliche Rahmenprofilteile und Knotenstel­ len je einer Cockpit-Hälfte gemeinsam als monolithische Faserverbund­ struktur aus entsprechenden Faserlagen-Zuschnitten in einem einzigen Formwerkzeug ausgeformt und ausgehärtet werden. Eine solche Bauweise bringt zwar eine große Fertigungsgenauigkeit und Gewichtsersparnis, erfordert aber einen hohen Fertigungsmittel- und manuellen Arbeitsauf­ wand und genügt zudem wegen der fehlenden interlaminaren Faserbindung, gerade auch im kritischen Knotenstellenbereich und an der Nahtstelle zwischen den Cockpit-Hälften, nicht der Forderung nach einer hinsicht­ lich des Faserverlaufs lastgerecht gestalteten Faserverbundstruktur.Furthermore, a cockpit frame is in scaffold from DE 38 26 636 C2 known construction, in which all frame profile parts and nodes  len a cockpit half together as a monolithic fiber composite structure from appropriate fiber layer blanks in one Forming tool are molded and cured. Such a construction brings great manufacturing accuracy and weight savings, but requires a high manufacturing resources and manual work wall and is also sufficient because of the lack of interlaminar fiber binding, especially in the critical node area and at the interface between the cockpit halves, not asking for a view The fiber composite structure is designed to match the fiber orientation.

Aufgabe der Erfindung ist es, einen Fachwerk-Tragrahmen der eingangs genannten Art zu schaffen, der auf großseriengerechte, fertigungsmäßig einfache und kostengünstige Weise als integrale Rahmenstruktur mit ei­ nem vor allem im Knotenstellenbereich lastgerechten Faserverlauf her­ zustellen ist.The object of the invention is a truss support frame at the beginning to create the type mentioned, on a large-scale, manufacturing simple and inexpensive way as an integral frame structure with egg nem, especially in the area of the knots, in line with the load is to be delivered.

Diese Aufgabe wird erfindungsgemäß durch den im Patentanspruch 1 ge­ kennzeichneten Tragrahmen gelöst.This object is achieved by the ge in claim 1 marked support frame released.

Fig. 4 is a perspective view of the completed support frame node with the associated frame profile parts shown only in the node connection area.

Der in Fig. 1 gezeigte Kraftfahrzeug-Tragrahmen 2 ist aus einzelnen, getrennt voneinander vorgefertigten Rahmenprofilteilen 4 zusammenge­ setzt, die jeweils als Faserverbund-Profilstücke mit einem beispiels­ weise rechteckigen Hohlprofilquerschnitt ausgebildet und im konsoli­ dierten bzw. ausgehärteten Zustand jeweils über Knotenstücke 6, welche ebenfalls aus Faserverbundwerkstoff bestehen, fachwerkartig zu einer integralen Rahmenstruktur verbunden sind.The motor vehicle support frame 2 shown in Fig. 1 is composed of individual, separately prefabricated frame profile parts 4 , each formed as a fiber composite profile pieces with an example rectangular hollow profile cross-section and in the consolidated or hardened state each via node pieces 6 , which also consist of fiber composite material, are truss-like connected to an integral frame structure.

Die Fertigung der Knotenstücke 6 und ihre Anbindung an die zugehörigen Rahmenprofilteile 4 wird im einzelnen für das in Fig. 1 gezeigte Kno­ tenstück 6A anhand der Fig. 2 bis 4 erläutert. Zunächst wird im Wege eines mechanisierten Fertigungsprozesses aus geeigneten Verstärkungs­ fasern, etwa Glas-, Carbon- oder Aramidfasern, ein textiler Faservor­ formling 8 (Fig. 2) in Form eines Fasergeflechtes oder -gestrickes hergestellt, dessen Faserstruktur der Geometrie des fertigen Knoten­ elements entspricht und dessen Faserorientierung während des textilen Fertigungsprozesses in Übereinstimmung mit dem Kräfteverlauf des Kno­ tenstücks 6A im fertiggestellten Tragrahmen gewählt wird. Dementsprechend besitzt der Faservorformling 8 aus Gründen einer last­ optimalen Steifigkeit und Festigkeit eine dreidimensionale Faser­ orientierung mit schrägverlaufenden, sich z. B. unter 90° kreuzenden Faseranteilen zur Schubkraftübertragung, denen unidirektionale Faser­ anteile zugemischt sind, welche die Normalkraftbelastungen des Knoten­ stücks 6A im fertigen Tragrahmen 2 übernehmen. Zwischen die Verstär­ kungsfasern sind in gleichförmiger Verteilung thermoplastische Fasern eingeflochten oder eingestrickt, die bei der späteren Konsolidierung des Knotenelements 6A die Faserverbundmatrix bilden. Der Faservorform­ ling 8 ist mit Aufnahmetaschen 10, in die die zugehörigen Rahmenpro­ filteile 4 etwa mit Hilfe eines Handhabungsroboters eingesetzt werden, und mit sich stegartig zwischen den Aufnahmetaschen 10 erstreckenden Wandabschnitten 12 versehen.The manufacture of the node pieces 6 and their connection to the associated frame profile parts 4 is explained in detail for the node piece 6 A shown in FIG. 1 with reference to FIGS . 2 to 4. First, by means of a mechanized manufacturing process from suitable reinforcing fibers, such as glass, carbon or aramid fibers, a textile fiber preform 8 ( FIG. 2) is produced in the form of a fiber mesh or knitted fabric, the fiber structure of which corresponds to the geometry of the finished knot element and whose fiber orientation is chosen during the textile manufacturing process in accordance with the force profile of the knot ten piece 6 A in the finished support frame. Accordingly, the fiber preform 8 has a three-dimensional fiber orientation with inclined, z. B. at 90 ° crossing fiber portions for shear force transmission, the unidirectional fiber portions are mixed, which take over the normal force loads of the node piece 6 A in the finished support frame 2 . Between the reinforcing fibers, thermoplastic fibers are woven or knitted in a uniform distribution, which form the fiber composite matrix during the subsequent consolidation of the node element 6 A. The fiber preform ling 8 is provided with receiving pockets 10 , into which the associated frame parts 4 are used, for example, with the aid of a handling robot, and provided with wall sections 12 extending in a web-like manner between the receiving pockets 10 .

Nach dem Einsetzen der Rahmenprofilteile 4 in die Aufnahmetaschen 10 erfolgt die Konsolidierung des Faservorformlings 8 und dessen integra­ le Verbindung mit den vorgefertigten Rahmenprofilteilen 4 in einem einzigen Fertigungsschritt mit Hilfe des in Fig. 3 gezeigten, zweitei­ ligen Formwerkzeugs 14, in welchem die Rahmenprofilteile 4 im Bereich ihrer knotenseitigen Endabschnitte lagegenau fixiert und der Faservor­ formling 8 unter der Druck- und Wärmeeinwirkung des Formwerkzeugs 14 zu einer sich integral mit den Rahmenprofilteilen 4 verbindenden Fa­ serverbundstruktur verdichtet und konsolidiert wird, wobei die thermo­ plastischen Faseranteile im Faservorformling 8 infolge der Temperatur­ einwirkung erweichen und gleichförmig über die Faserstruktur des Vor­ formlings 8 verteilt werden. Dabei ergibt sich zwischen den gegensei­ tigen Kontaktflächen des Vorformlings 8 und der Rahmenprofilteile 4 im Bereich der Aufnahmetaschen 10 eine innige flächige Verklebung und Ma­ terialbindung, insbesondere dann, wenn für die Rahmenprofilteile 4, wie bevorzugt, als Faserverbundmatrix ebenfalls ein Thermoplast ver­ wendet wird. Zusätzlich werden die Rahmenprofilteile 4 - wie bei 16 gezeigt - formschlüssig mit dem Knotenstück 6A verbunden und enthal­ ten zu diesem Zweck ein Formstück 18 z. B. aus Schaumstoff, das bei der Fertigung der Profilteile 4 in die endseitigen Anschlußbereiche einge­ fügt wird. In gleicher Weise werden auch die übrigen Knotenstellen 6 ausgebildet, woraufhin die Fachwerkstruktur fertiggestellt ist. Ein Nacharbeiten ist nicht erforderlich, da keine Spannungen oder Verzüge durch Fertigungsungenauigkeiten in der Struktur verbleiben.After inserting the frame profile parts 4 in the receiving pockets 10 , the consolidation of the fiber preform 8 and its integra le connection with the prefabricated frame profile parts 4 takes place in a single production step with the aid of the two-part molding tool 14 shown in FIG. 3, in which the frame profile parts 4 in area positionally accurate fixing of their knot side end portions and the Faservor preform 8 under the pressure and heat of the mold 14 to integrally connected with the frame profile parts 4 Fa server composite structure is compacted and consolidated, with the thermoplastic fiber components action in the fiber preform 8 due to the temperature soften and be uniformly distributed over the fiber structure of the preform 8 . In this case, results between the gegensei term contact surfaces of the preform 8 and the frame profile members 4 in the region of the receiving pockets 10 an intimate area bonding and Ma terialbindung particularly when, ver as a fiber composite matrix is also a thermoplastic applies for the frame profile parts 4, as preferred. In addition, the frame profile parts 4 - as shown at 16 - positively connected to the node 6 A and for this purpose contain a fitting 18 z. B. made of foam, which is inserted in the manufacture of the profile parts 4 in the end connection areas. The other nodes 6 are also formed in the same way, whereupon the framework structure is completed. Reworking is not necessary as there are no tensions or distortions due to manufacturing inaccuracies in the structure.

Bei Verwendung eines Duromersystems anstelle eines Thermoplasten als Faserverbundmatrix wird der trockene, textile Vorformling 8 ebenfalls zusammen mit den zugehörigen Rahmenprofilteilen 4 in das Formwerkzeug 14 eingelegt und dort z. B. im Wege der Harz-Injektionsmethode mit dem Duromersystem, etwa einem Epoxidharz, durchtränkt und dann - wiederum unter Wärme- und Druckeinwirkung - zu dem fertigen Knotenelement aus­ gehärtet. Die Rahmenprofilteile 4 können auch aus einem Faserverbund­ werkstoff, der ebenfalls eine Duromermatrix enthält, oder auch aus ei­ nem metallischen Werkstoff vorgefertigt werden.When using a thermoset system instead of a thermoplastic as a fiber composite matrix, the dry, textile preform 8 is also placed together with the associated frame profile parts 4 in the molding tool 14 and there z. B. by means of the resin injection method with the duromer system, such as an epoxy resin, soaked and then - again under the action of heat and pressure - hardened to the finished node element. The frame profile parts 4 can also be prefabricated from a fiber composite material, which also contains a duromer matrix, or from a metallic material.
