Embodiment Construction

[0028] figure 1 Shown is the front end region of a longitudinal member 1 with a hollow profile and a cross member 2 fastened to the longitudinal member 1 of the front end of the vehicle body, not shown further, with two parallel to each other and extending in the longitudinal direction of the vehicle (X direction) The longitudinal beam 1 and the cross beam 2 connecting the two longitudinal beams 1. The cross member 2 supports, in a known manner, the front module components of the motor vehicle body, which are dimensionally precisely connected to the adjoining body components. This requires that the beams 2 be dimensionally accurately configured with the longitudinal beams 1 in the Y-direction (transverse), Z-direction (vertical) and X-direction.

[0029]The cross member 2 has a front deformation element 3 and a side deformation element 4 with a hollow profile oriented in the longitudinal direction of the vehicle. On the deformation element 4 ( figure 1 Only the left-hand de...

Abstract

Die Erfindung betrifft eine Vorrichtung, insbesondere am Vorbau eines Kraftfahrzeuges, zum Verbinden des Endbereichs eines ersten, ein Hohlprofil aufweisenden Tragers (1) mittels einer Schottplatte (6) mit einem Anschlussbereich (5), insbesondere einem Anschlussflansch, eines zweiten, ein Hohlprofil aufweisenden Tragers (2), wobei zum Ausgleich von Fertigungstoleranzen zwischen dem ersten Trager (1) und der Schottplatte (6) ein mit einer Stirnseite wenigstens bereichsweise um eine Ausnehmung (10) in der Schottplatte (6) herum angeordnetes Verbindungselement (8) vorgesehen ist, welches Verbindungselement (8) weiter mit dem ersten Trager (1) verbunden ist. Erfindungsgemass ist ein Ausnehmungsrandkantenbereich (10a) der Schottplatten-Ausnehmung (10) und damit die Schottplatten-Ausnehmung (10) so dimensioniert und ausgebildet, insbesondere ein Ausnehmungsrandkantenbereich (10a) so nach radial innen in den Hohlprofilbereich des Trageranschlussbereichs einragend ausgebildet, dass ein sich an den Anschlussbereich (5) des zweiten Tragers (2) anschliessender, stirnseitiger Querschnittswandbereich (4a, 4a') des zweiten Tragers (2) innerhalb eines definierten Toleranzbereiches mittelbar oder unmittelbar von der Schottplatte (6) abgestutzt ist.

Description

technical field [0001] The invention relates to a device, in particular at the front end of a motor vehicle body, for aligning the end regions of a first beam, in particular a longitudinal beam, with a hollow profile, with a second beam, in particular a transverse beam, with a hollow profile The connecting region is connected, wherein, in particular to compensate for manufacturing tolerances, a connecting element is arranged between the first beam and the partition wall with the end faces at least partially around the opening in the partition wall, which in turn is connected to the first beam connect. Background technique [0002] DE 10 2005 054 250 A1 describes such an arrangement, in which the webs are each connected to the longitudinal beams via connecting elements. The connecting piece consists of two sheet steel corners forming a right angle, one of which is butt-welded to the bulkhead and the other welded to the end area of ​​the stringer, which in the assembled state...
