Abstract

The metallic inlays are formed as a grid of uninsulated live rails (e.g. 10) with coupling pieces comprising threaded bolts (17) and plug sockets. The bolt connections are designed as rapid action connections particularly connecting sockets. The flexible cables (15) located outside the floor section (1) are connected to the conducting rail (10) in the floor section via a clamping piece (18) and a nut (12) which is screwed onto the bolt connection (17). The floor section comprises a rigid plastic foam core (14) covered by a flass fibre reinforced outer layer (11). This foam core is divided into three sections by vertical extensions, the centre portion housing a control device and the two outer sections containing the storage batteries.

Description

2020th

Die Erfindung bezieht sich auf eine Bodengruppe für Kraftfahrzeuge, bestehend aus einem Kunststoffkörper in Sandwichbauweise mit eingeschäumten, dem Transport elektrischer Energie dienenden eigensteifen metallischen Einlagen.The invention relates to an underbody for motor vehicles, consisting of a plastic body in sandwich construction with foamed-in, inherently rigid metallic elements that are used to transport electrical energy Insoles.

Es ist bekannt. Befestigungselemente wie Rohre oder Leisten und auch für den späteren Zusammenbau des Fahrzeugs erforderliche Verbindungsteile sowie zur Verstärkung dienende Einlagen mit in das Sandwichbauteil einzubauen, so daß sie beim fertigen Bauteil im Schaumstoff und in den Deckschichten fest verankert sind (CH-PS 2 11 577).It is known. Fastening elements such as pipes or strips and also for the later assembly of the Vehicle required connecting parts as well as reinforcing inserts with in the sandwich component installed so that they are firmly anchored in the finished component in the foam and in the cover layers are (CH-PS 2 11 577).

In der Praxis führt das dazu, daß es nicht mehr möglieh ist, eine z. B. zur Erstellung einer Sandwichbodengruppe bestimmte Schäumform in der üblichen Rüstzeit mit der notwendigen Anzahl fest zu verankernder Verbindungselemente vorzubereiten. Auch für die Befestigung der Leitungssysteme für die Energieträger, die bisher als Rohrleitungen oder auch als isolierte Kabel für die Weiterleitung des elektrischen Stromes ausgebildet sein können, müssen zahlreiche Verankerungen in den relativ dünnwandigen Deckschichten der Sandwichbodengruppe angebracht werden. Durch diese umständlichen Vorbereitungsarbeiten werden die teuren Schäumformen vor Beginn einer jeden Ausschäumung eine unverhältnismäßig lange Zeitspanne hindurch belegt, was sich vor allem bei der Serienfertigung nachteilig auswirkt.In practice this means that it is no longer possible is, a z. B. to create a sandwich base group certain foam mold in the usual set-up time with the necessary number of fasteners to be firmly anchored. Also for fastening the line systems for the energy sources, which were previously as pipelines or also as insulated cables can be designed for the transmission of the electric current, must have numerous anchorages be attached in the relatively thin-walled cover layers of the sandwich floor assembly. Through this The expensive foaming molds are cumbersome preparatory work before the start of each foaming process a disproportionately long period of time, which is particularly evident in series production has a detrimental effect.

Die Vielzahl der einzeln im Sandwichbauteil zu verankernden metallischen Glieder beeinflußt aber nicht nur die Rüst- bzw. Fertigungszeiten in ungünstiger Weise, sondern kann auch die Steifigkeit und Widerstandsfähigkeit der Sandwichbodengruppe beeinträchtigen. The large number of metallic links to be anchored individually in the sandwich component does not have any influence only the set-up or production times in an unfavorable way, but can also affect the rigidity and resistance affect the sandwich floor assembly.

Es sind bei Kunststoffsandwichbodengruppen und bei Kunststoffsandwichaufbauten für Fahrzeuge zwar schon Verfahren bekannt, bei welchen durch das Einschäumen von eigensteifen Rohrsyslemen für die Verteilung des Reaktionsgemisches und zum Anschluß von Fahrzeugteilen eine Stützung des Schaumkernes erreicht wird (DT-AS 16 80 609). Ferner ist das Einschäumen von Rohren und das nachträgliche Einziehen von Drähten in diese zur Herstellung elektrischer Verbindüngen bekannt. Dies ist jedoch z. B. bei Elektrofahrzeugen wegen der dort oft notwendigen großflächigen Leiterquerschnitte und infolge der meist komplizierten Leitungsführungen aufwendig und schwer durchführbar. . ■ r, _iIt is true for plastic sandwich floor assemblies and plastic sandwich superstructures for vehicles already known methods in which by foaming in rigid pipe systems for distribution of the reaction mixture and for the connection of vehicle parts a support of the foam core is achieved (DT-AS 16 80 609). Furthermore, the foaming of pipes and the subsequent pulling in of Wires in this known for making electrical connections. However, this is e.g. B. in electric vehicles because of the large-area conductor cross-sections that are often necessary there and because of the mostly complicated ones Cable routing is complex and difficult to implement. . ■ r, _i

Aufgabe der Erfindung ist es, eine Bodengruppe gemäß der eingangs genannten Gattung vorzuschlagen, die für die Serienfertigung geeignet ist. bei der also vor allem die für die Vorbereitung der Schäumform erforderlichen Rüstzeiten kurz sind und bei deren Anwendung ferner eine möglichst große Anzahl von bei der weiteren Montage des Fahrzeugs notwendigen Arbeiten vorweggenommen bzw. überflüssig gemacht wird.The object of the invention is to provide a floor pan according to to propose the type mentioned above, which is suitable for series production. at the so before In particular, the set-up times required for preparing the foam mold are short and when they are used Furthermore, the greatest possible number of work necessary for the further assembly of the vehicle is anticipated or made superfluous.

Eine Lesung der Erfindungsaufgabe ist bei einer Bodengruppe der eingangs genannten Art darin zu sehen. daß die Einlagen als Gitter isolationsloser Stromschienen mit Kuppelstücken ausgebildet sind.A reading of the inventive task is at a floor pan of the type mentioned in the introduction. that the deposits as a grid of insulationless busbars are designed with coupling pieces.

Durch die Gesamtheit dieser Merkmale der Erfindung wird der Zeitaufwand zur Vorbereitung der Schäumform für das Einschäumen erheblich gemindert, weil für die zu verlegenden Leitungen für den Energiefluß nur noch ein zusammenhängendes Gitter gegenüber der Schäumform auszurichten und festzulegen ist. Ferner bringt die Erfindung den Vorteil, daß vor Beginn der weiteren Montage die Hauptstränge der KrafMeitung oder -leitungen bereits fertig verlegt sind, also weder weiteren Arbeitsaufwand, noch zusätzlichen Raum beanspruchen.The totality of these features of the invention, the time required to prepare the Foam form for foaming considerably reduced because of the lines to be laid for the flow of energy only a coherent grid has to be aligned and fixed in relation to the foaming mold. Furthermore, the invention has the advantage that the main strands of the Power line or lines have already been laid, so do not take up any additional work or additional space.

Vorteilhaft können ferner die Kuppelstücke als Schnrllanschlüsse z. B. in Form von Steckverbindungen ausgebildet sein. Die Endstücke des eingeschäumten Gitters können die Oberfläche des Sandwichbaukörpers durchdringen. Sie gestatten auf diese Weise ohne Nacharbeit den Anschluß der Kraftleitungen an die Energiequellen und an die Energieverbraucher.Advantageously, the coupling pieces can also be used as quick connections z. B. in the form of connectors be trained. The end pieces of the foamed-in grid can form the surface of the sandwich structure penetrate. In this way, they allow the power lines to be connected to the Energy sources and to energy consumers.
