Abstract

The module has a mounting carrier (3) for holding aggregates (5), on which a collision force acts during vehicle collision, where the mounting carrier is movable in a non-destructive manner during the vehicle collision. The mounting carrier is guided in a longitudinal movable manner over a lateral bolt (21) in a connecting link (25) of a holding unit, during the vehicle collision. A blocking device (23) releases the bolt of the mounting carrier in a longitudinal direction of the vehicle.

Description

The The invention relates to a vehicle end module, in particular a front end module for one Vehicle body according to the preamble of claim 1.

end modules for one Vehicle body include, among other things, a mounting bracket Picking up a cooler package on. With such end modules is a good deformation behavior required to complete in case of a vehicle collision on the mounting bracket his cooler package to achieve harm reduction.

From the EP 1 232 931 B1 is a generic, designed as a front-end module vehicle end module for a vehicle body is known which has a mounting bracket for holding aggregates. Front side in front of the mounting bracket, a cross member is connected to the mounting bracket. In a front impact collision, the cross member can be pressed against the mounting bracket. In order to prevent damage to the radiator pack carried by the mounting bracket, the mounting bracket is provided with a predetermined breaking point. In the case of a front impact such a cooler pack holding section can break out of the mounting bracket. Here, the mounting bracket is disadvantageously destroyed, so that in case of repair, both the cross member and the mounting bracket of the cooler package must be replaced.

The The object of the present invention is to provide a vehicle end module, in particular to provide a front-end module for a motor vehicle, in a vehicle collision an improved deformation behavior shows.

The The object of the invention is characterized by the features of claim 1 solved. Advantageous developments of the invention are disclosed in the subclaims.

According to the characterizing one Part of claim 1 is the mounting bracket of the end module at a Vehicle collision non-destructive displaced. This can be guaranteed be that mounting carrier remains undamaged together with its units in the event of a vehicle collision. Such undamaged mounting bracket can therefore easily with a subsequent repair from the damaged End module removed and again with a replaced end module be used.

For the non-destructive Displacement in the vehicle collision case, the mounting bracket preferred at least one lateral bolt on, in a backdrop of a Retaining element is guided longitudinally displaceable. By means of the setting of the holding element, the mounting carrier is in collision a defined displacement path is advantageously predetermined.

Prefers the backdrop may be associated with a blocking element that the bolt of the mounting carrier in the vehicle longitudinal direction keeps stationary in the scenery. By means of the blocking element can be ensured that the mounting bracket normally stored without play in the backdrop of the retaining element is. In this case, the blocking element can be dimensioned so that it guided in the backdrop of the retaining element bolt in a vehicle collision releases. The mounting carrier can then be moved along the scenery.

at a front-end vehicle collision is a collision impact on the mounting bracket towards the vehicle rear exercised. The locking element may preferably have a retention force a relocation of the assembly carrier counteract. In this case, the blocking element can be dimensioned so that it is destroyed by a certain impact force through the bolt of the mounting bracket, so that a displacement movement of the mounting bracket within the backdrop of the retaining element is released.

manufacturing technology Cheap It is when the blocking element as a fixed in the backdrop of the Holding element inserted sleeve is preferably made of plastic.

In order to even with larger impact forces of the mounting bracket damage remains, it is advantageous if the backdrop of the retaining element back is open. In the event of a collision, therefore, first the bolt of the mounting bracket that Overcome blocking element and shift along the scenery until the mounting bracket on the back Damage-free from the scenery forced out becomes. Only at very large Impact pulses may thus damage the mounting bracket or of the cooler package come.

Prefers the retaining element is a bulkhead of a front to the mounting bracket mounted cross member. The bulkhead of the cross member can one in the vehicle longitudinal direction have angled tab in which the backdrop is formed. The backdrop may preferably be formed in the bulkhead plate slot be, in which the at least one bolt of the mounting bracket is longitudinally displaceable is stored.

The front-end module can be mounted by means of the bulkhead of the cross member front of an associated bulkhead plate of the body longitudinal member. As mentioned above, thus, the bulkhead of the cross member can not only for Monta ge of the front-end module on the body side member, but also serve as a carrier of the backdrop of the mounting bracket bolt.

at a front-end vehicle collision are first impact forces in the Cross member of the Initiated front-end module. As a result, the cross member can deform and this against the mounting bracket depressed become. exceeds thus in the mounting bracket introduced impact force a predetermined value, so can the at least one bolt of the mounting bracket destroy the locking element, whereby the mounting carrier with his guided in the scenery Bolt to the vehicle rear can be relocated. Preference may be the back the backdrop should be open, allowing the displacement movement of the mounting carrier not blocked by, for example, a rear gate stop is, but rather the mounting bracket together with its lateral Bolts are pushed out of the gate without resistance can.

Around in the event of a collision, a non-destructive displacement movement of the mounting carrier To achieve it is preferable if the at least one lateral Bolt is guided in a vehicle transverse direction through the backdrop. Preferably, the scenery in the vehicle longitudinal direction may be preferred extend.

following is an embodiment the invention with reference to the attached Figures shown.

It demonstrate:

1 in a perspective, roughly schematic partial view of a front-end module; and

2 in a partial side view of the detail X from the 1 ,

In the 1 is a left lower corner of a front-end module 1 shown on a vehicle front. The frontend module 1 is formed at the not shown, in the transverse direction y opposite right vehicle front side substantially symmetrical.

The frontend module 1 has a frame-shaped plastic mounting bracket 3 for receiving a dash-dot line indicated cooler unit. In the vehicle longitudinal direction x in front of the radiator unit 5 extends a cross member 7 that together with its lateral deformation elements 9 how a vehicle rear side open U-shaped frame is formed. That in the 1 Deformation element shown 9 of the crossbeam 7 is at its back end with a bulkhead plate 11 in connection, by means of the entire front-end module 1 via screw connections 13 to the front end 15 a dash-dotted lines indicated body longitudinal member 17 is mounted.

According to the 1 is the bulkhead plate 11 of the crossbeam 7 with two inside right-angled bent upper and lower flaps 19 Mistake. The crossbeam 7 is over the tabs 19 its bulkhead 11 by means of bolts 21 on a side part of the mounting bracket 3 screwed.

For this purpose, each of the bolts 21 through a Kunststoffschraubhülse 23 led, as in the 1 and 2 is shown. The plastic screw sleeve 23 is in accordance with the 1 and 2 in a slot 25 the respective upper or lower flap 19 the bulkhead plate 11 used. The slot 25 extends in the vehicle longitudinal direction x and has according to the 2 at its front end a circular bulge 27 on, in which the screw sleeve 23 is used. The diameter of the circular bulge 27 is greater than a gap width a of the elongated hole 25 to the screw sleeve 23 stationary at the front end of the oblong hole 25 to position. At its rear end 29 is the slot 25 also expanded with an enlarged gap width a and goes the slot 25 from the right angle bent tab 19 in the bulkhead 11 above. This is the slot 25 open at the back. Through this open end 29 the long hole 25 can in the following described crash case of the bolt 21 Resistant from the slot 25 be pressed.

The following is based on the detail view according to the 2 the deformation behavior of the front-end module 1 at a front impact shock F described. The collision shock F is first large area in the cross member 7 of the front-end module 1 initiated, the about the deformation elements 9 on the body side members 17 is supported. With a correspondingly large impact force, the deformation elements 9 upset, causing the cross member 7 in contact with the mounting bracket 3 comes and pushes it towards the vehicle rear, as it is in the 2 indicated by dash-dotted lines.

With the displacement movement of the mounting bracket 3 to the vehicle rear side is the bolt 21 from the screw sleeve 23 torn, stuck in the circular bulge 27 the long hole 25 is anchored. The torn screwed sleeve 23 is in the 2 shown in phantom. In this way, the screw acts 23 Normally as a blocking element, the one in the longitudinal direction x play-free mounting of the mounting bracket 3 guaranteed. In contrast, the screw is 23 dimensioned so that in case of collision by the bolt 21 of the mounting carrier 3 is destroyed and thus a free displacement movement of the mounting bracket 3 in the vehicle longitudinal direction x allows.

The slot 25 thus acts as a backdrop, a guided, and resistance-free displacement of the mounting bracket 3 towards the vehicle rear side. With a correspondingly large impact force of the bolt 21 according to the 2 through the open rear end 29 the long hole 25 pushed out without being blocked by about a gate element. This ensures that even with larger impact forces that the mounting bracket 3 of the radiator unit 5 remains free of damage.
