Abstract

The rear end of the chassis of a vehicle designed for rigidity so as to protect the passenger compartment in the extent of a collision, has two square section tubes (5, 6) forming the main longitudinals of the chassis. Adaptor pieces (19, 20) attached to the rear bumper (4) by funnel shaped portions (17, 18) fit into the open ends of these longitudinals. These are secured by bolts. The wheel housings (21, 22) end in open curved portions (23, 24) with flat, flanged up tops (25, 26) and across them is bolted a strengthening member (27) which is U shaped in cross section.

Description

Selbsttragende Karosserie mit zwei durch Querträger vor-Self-supporting body with two cross members

bundenen Längsträngern für Kraftfahrzeuge Die Erfindung bezieht sich auf eine selbsttragende Karosserie mit zwei durch querträger verbundenen Längsträgern für Kraftfahrzeuge. Es ist bekaniot, den Fahrgastraum des Fahrzeugs gegeil Deformationen unempfindlich zu gestalten und die Vorformungsarbeit bei einem möglichen Zusammenstoß durch die Endzonen der Längsträger aufuehmen zu lassen (VDl-Nachrichten Nr. 36, v. 5.9.1975, Seite 1 unten). Weiter ist es bekaiirit Deformationsglieder zwischen der Stoßstange und den Enden der Längsträger anzuordnen (DT-OS 2 301 605).bound longitudinal members for motor vehicles The invention relates on a self-supporting body with two longitudinal members connected by cross members for automobiles. It is known to deform the passenger compartment of the vehicle horny to make insensitive and the preforming work in the event of a possible collision through the end zones of the side members (VDl-Nachrichten No. 36, v. 5.9.1975, page 1 below). Further it is known deformation links between the bumper and the ends of the side members (DT-OS 2 301 605).

Aufgabe der Erfindung ist es, die Frontpartic einer selbsttragenden Karosserie mit zwei durch Querträger verbundenen Eängsträgern zu vereinfachen und zu vervollkammnen.The object of the invention is to provide the front part of a self-supporting To simplify body with two cross members connected by cross members and to perfect.

Die Lösung besteht darin, daß die Stoßstange an den Enden der Längsträger befestigt ist und den einzigen Querträger vor der Vorderachse bildet. Dadurch läßt sich der übliche Querträger, der die Enden der Längsträger vorn mitoinander verbindet einsl)arell. Weiter läßt stich ein Triebwerk mit einer viel Raum in Längsrichtung einnebmenden Mchrzylinder-Reihenbrennkraftmaschine anordnen, obwchl die Vorbaulänge vor der Vorderachse klein gehalten wird. Die Stoßstange kanll an de Enden der Längsträger verschraubt sein, so daß sie sich leicht auswechseln und sich das Antriebsaggregat nach vorn ausbauen läßt. Zwischen der Stoßstange und den vorderen Enden der beiden Längsträger lassen sich Vorformmungsglieder anordnen, die mit einer trapezförmigen Erweiterung an der Stoßstange und mit einem rechteckigen Profil in den Längsträgern befestigt sind. Zuglcich übernimmt jedes Verformungsglied eine weitere Funktion, nämlich die lösbare Schraubverbindung oder eine lösbare Raupenschweißverbindung: zwischen den Trägern und der Stoßstange in einfacher Weise zu schaffen. Zwischen den die Radhäuser nach vorn abschließenden Bauteilen kann ein anschraubbarer Querträger angeordnet sein; dann läßt sich das Antriebsaggregat oder die Brennkraftmaschine nach vorn hinaus heben bzw. ist für Wartungs- und Raparaturarbeiten von vorn gut zugänglich.The solution is that the bumper is attached to the ends of the side members is attached and forms the only cross member in front of the front axle. This lets the usual Cross member that joins the ends of the front side members Einsl) arell connects with one another. Next lets stab an engine with a lot Arrange space in the longitudinal direction occupying a multi-cylinder in-line internal combustion engine, although the stem length in front of the front axle is kept small. The bumper can be screwed to the ends of the side members so that they can be easily replaced and the drive unit can be removed to the front. Between the bumper and Preforming members can be arranged at the front ends of the two longitudinal members, those with a trapezoidal extension on the bumper and with a rectangular one Profile are fixed in the side members. At the same time, every deformation element takes over another function, namely the detachable screw connection or a detachable welded caterpillar connection: between the beams and the bumper in a simple manner. Between the components closing the wheelhouses towards the front can be a screw-on cross member be arranged; then the drive unit or the internal combustion engine Lift out to the front or is good for maintenance and repair work from the front accessible.

Die Zeichnung zeigt ein Ausführangsbeispiel der Erfindung: Fig. 1 eine perspektivische Darstellung; Fig. 2 eine Einzelheit aus Fig. 1 in vergrößertem Maßstab.The drawing shows an exemplary embodiment of the invention: FIG. 1 a perspective view; FIG. 2 shows a detail from FIG. 1 on an enlarged scale Scale.

Die selbsttragende Karosserie enthält zwei Längsträger 2, 3, die durch nicht dargestellte Querträger verbunden sind. Die Stoßstange 4, vorzugsweise mit geschlossenem Profil, ist an den Enden 5, 6 der Längsträger 2, 3 befestigt und bildet den einzigen Querträger vor der nicht dargestellten Vorderachse. Die Stoßstange 4 kann an den Enden 5, 6 der Längsträger 2, 3 mit Schrauben 11, 12, 13, 14 angeschraubt sein.The self-supporting body contains two longitudinal members 2, 3, which through not shown cross members are connected. The bumper 4, preferably with closed profile, is attached to the ends 5, 6 of the longitudinal beams 2, 3 and forms the only cross member in front of the front axle, not shown. The bumper 4 can be screwed to the ends 5, 6 of the longitudinal members 2, 3 with screws 11, 12, 13, 14 be.

Zwischen der Stoßstange 4 und den vorderen Enden 5, 6 der Längsträger siiid in Verlängerung der Längsträger Verformungsglieder 15, 16 angeordnet. Sie sind mit einer Erweiterung 17 bzw. 18 aii der Stoßstange 4 mit einem rechteckigen Profil 19 bzw. 20 an den Längsträgern befestigt. Die Verformungsglieder 15, 16 können an einem Ende auch mit leicht trennbarer Schweißverbindung z. B. raupe, mit der Stoßstange bzw. mit den Längsträgern verbunden sein. Zwischen den die Kadhäuser 21 bzw. 22 nach vorn abschließenden Bauteilen 23, 24 ist ein bei 25 bzw. 26 aschraubbarcr Querträger 27 angeordnet.Between the bumper 4 and the front ends 5, 6 of the side members siiid deformation members 15, 16 are arranged in an extension of the longitudinal beams. she are with an extension 17 or 18 aii of the bumper 4 with a rectangular Profile 19 or 20 attached to the side members. The deformation members 15, 16 can at one end also with easily separable welded connection z. B. caterpillar, with the Bumper or be connected to the side members. Between the Kadhäuser 21 and 22 to the front closing components 23, 24 is a screw barcr at 25 and 26, respectively Cross member 27 is arranged.

Dadurch, daß die Stoßstange 4 den einzigen Querträger vor der Vorderachse bildet, ist ein vergrößerter bzw. nach vorn verlängerter Raum 28 geschaffen. Bei einem kleineren Auffahrunfall werden nur die Verformungsglieder 15 und 16 verformt, währcnd die vorzugsweise mit Gummi oder gummiähnlichen Schutzleisten belegte Stoßstange und die vorderen Enden 5 und 6 der Längsträger 2 und 3 nicht verformt oder beschädigt werden. Nach Lösen der Schrauben 11, 12, 13, 14 lassen sich die Verformungsglieder 15 und 16 in einfacher Weise austauschen. Bei einem schweren Auffahrunfall verformen sich nicht nur die Verformungsglieder 15 und 16, sondern auch die im wesentlichen gradlinigen Längsträger 2 und 3. Für den Ausbau des Antriebsaggregats nach vorn können der Quertriiger 27 und die Stoßstange 4 abgeschraubt werden. Die Zugänglichkeit und Wartung des Antriebsaggregats ist so wesentlich vereinfacht.Because the bumper 4 is the only cross member in front of the front axle forms, an enlarged or forward lengthened space 28 is created. at In a minor rear-end collision, only the deformation members 15 and 16 are deformed, during the bumper, which is preferably covered with rubber or rubber-like protective strips and the front ends 5 and 6 of the side members 2 and 3 are not deformed or damaged will. After loosening the screws 11, 12, 13, 14, the deformation members Replace 15 and 16 in a simple manner. Deform in the event of a serious rear-end collision not yourself only the deformation members 15 and 16, but also the essentially straight longitudinal members 2 and 3. For removing the drive unit The cross member 27 and the bumper 4 can be unscrewed to the front. the Accessibility and maintenance of the drive unit is thus significantly simplified.
