Abstract

A front end module for covering a front of a front vehicle part of a motor vehicle includes a crossmember that is connectable to longitudinal carriers of a motor vehicle frame so as to absorb loads of a bumper. An upper frame element is connected to the crossmember for supporting an engine hood. A receiving region for receiving a radiator grill is disposed between the crossmember and the upper frame element. Fastening elements disposed on the crossmember and/or the upper frame element are configured to fasten an intercooler for cooling charge air of a turbocharger, with respect to the driving direction, in front of a wheel arch that receives a front wheel. A crash structure is connected to the fastening elements for absorbing impact energy by way of plastic deformation and covers a majority of the front wheel in an installed state of the front end module.

First claim

What is claimed is:

1. A front end module for covering a front of a front vehicle part of a motor vehicle, the front end module comprising:
a crossmember that is connectable to longitudinal carriers of a motor vehicle frame so as to absorb loads of a bumper,
an upper frame element which is connected to the crossmember for supporting an engine hood, a receiving region for receiving a radiator grill being disposed between the crossmember and the upper frame element,
fastening elements disposed on at least one of the crossmember or the upper frame element and configured to fasten an intercooler for cooling charge air of a turbocharger in front of, with respect to a driving direction, a wheel arch that receives a front wheel, and
a crash structure which is connected to the fastening elements for absorbing impact energy by way of plastic deformation, the crash structure covering a majority of the front wheel arranged in the wheel arch in an installed state of the front end module,
wherein the crash structure has a cutout which points toward a vehicle center line and is configured to receive the intercooler or a different intercooler for cooling the charge air of the turbocharger.

2. The front end module as claimed in claim 1 , wherein the crash structure has a load-bearing element which is configured as a load-bearing frame for fastening a motor vehicle assembly including at least one of a filter, a pump or a container in a load-bearing manner.

3. The front end module as claimed in claim 1 , wherein, in the installed state of the front end module, the crash structure is arranged completely in a direction laterally away from a vehicle center line to an adjacent longitudinal carrier of the motor vehicle frame so as to be arranged in a region which lies laterally outside a load-bearing frame of the motor vehicle.

4. The front end module as claimed in claim 1 , wherein the crash structure has at least one of a honeycomb structure, a foam structure or crash boxes.

5. The front end module as claimed in claim 1 , wherein, in a part region which points away from a vehicle center line, the crash structure has a greater thickness in the driving direction than outside the part region, and wherein a ratio of a maximum thickness d max of the part region to a thickness d m of the crash structure which is averaged over a surface region of the crash structure which points in the driving direction is 1.1≤d max /d m ≤4.0.

6. The front end module as claimed in claim 1 , wherein the crash structure has at least one mounting device for fastening to a body of the motor vehicle and at least one of the crossmember or to the upper frame element.

7. The front end module as claimed in claim 1 , wherein the crash structure is configured to initiate a steering movement of a front axle of the vehicle in a first impact phase.

8. The front end module as claimed in claim 1 , wherein the crash structure has a honeycomb structure, and wherein at least part of the honeycombs of the honeycomb structure are oriented obliquely with respect to the driving direction.

9. A front vehicle part for a motor vehicle, comprising:
a left-hand longitudinal carrier which forms part of a motor vehicle frame,
a right-hand longitudinal carrier which forms part of the motor vehicle frame,
a left-hand wheel arch which forms part of a motor vehicle body,
a left-hand front wheel which is arranged in the left-hand wheel arch,
a right-hand wheel arch which forms part of the motor vehicle body,
a right-hand front wheel which is arranged in the right-hand wheel arch, and
a front end module comprising:
a crossmember connected to the longitudinal carriers so as to absorb loads of a bumper,
an upper frame element which is connected to the crossmember for supporting an engine hood, a receiving region for receiving a radiator grill being disposed between the crossmember and the upper frame element,
fastening elements disposed on at least one of the crossmember or the upper frame element and configured to fasten an intercooler for cooling charge air of a turbocharger, with respect to a driving direction, in front of at least one of the wheel arches, and
at least one crash structure which is connected to the fastening elements for absorbing impact energy by way of plastic deformation, the at least one crash structure being positioned, with respect to the driving direction, in front of at least one of the front wheels so as to cover, in the driving direction, a majority thereof,

wherein the at least one crash structure has a cutout which points toward a vehicle center line and is configured to receive the intercooler or a different intercooler for cooling the charge air of the turbocharger.

10. The front vehicle part as claimed in claim 9 , wherein the at least one crash structure is fastened directly to at least one of the wheel arches.

11. A front end module for covering a front of a front vehicle part of a motor vehicle, the front end module comprising:
a crossmember that is connectable to longitudinal carriers of a motor vehicle frame so as to absorb loads of a bumper,
an upper frame element which is connected to the crossmember for supporting an engine hood, a receiving region for receiving a radiator grill being disposed between the crossmember and the upper frame element,
fastening elements disposed on at least one of the crossmember or the upper frame element and configured to fasten an intercooler for cooling charge air of a turbocharger in front of, with respect to a driving direction, a wheel arch that receives a front wheel, and
a crash structure which is connected to the fastening elements for absorbing impact energy by way of plastic deformation, the crash structure covering a majority of the front wheel arranged in the wheel arch in an installed state of the front end module,
wherein, in a part region which points away from a vehicle center line, the crash structure has a greater thickness in the driving direction than outside the pan region, and wherein a ratio of a maximum thickness d max of the part region to a thickness d m of the crash structure which is averaged over a surface region of the crash structure which points in the driving direction is 1.1≤d max /d m ≤4.0.

12. The front end module as claimed in claim 11 , wherein the crash structure has at least one of a honeycomb structure, a foam structure or crash boxes.

13. The front end module as claimed in claim 11 , wherein the crash structure has a honeycomb structure, and wherein at least part of the honeycombs of the honeycomb structure are oriented obliquely with respect to the driving direction.

14. The front end module as claimed in claim 11 , wherein the crash structure is configured to initiate a steering movement of a front axle of the vehicle in a first impact phase.

15. The front end module as claimed in claim 11 , wherein the crash structure has at least one mounting device for fastening to a body of the motor vehicle and at least one of the crossmember or the upper frame element.

16. The front end module as claimed in claim 11 , wherein, in the installed state of the front end module, the crash structure is arranged completely in a direction laterally away from a vehicle center line of the motor vehicle frame so as to be arranged in a region which lies laterally outside a load-bearing frame of the motor vehicle.

17. The front end module as claimed in claim 11 , wherein the crash structure has a load-bearing element which is configured as a load-bearing frame for fastening a motor vehicle assembly including at least one of a filter, a pump or a c
