Abstract

The present invention relates to a wheel air gap for a motor vehicle of which according to the invention at least one section of the wheel air gap open air comprises a sound-absorbing material.

First claim

The invention claimed is:

1. A wheel air dam for a motor vehicle, wherein at least one exposed section of the wheel air dam that is impacted by airflow when moving forward, comprises LWRT as a sound-absorbing material.

2. The wheel air dam for a motor vehicle according to claim 1 , wherein the sound-absorbing material forms at least one section of an exposed outward-facing surface of the wheel air dam.

3. The wheel air dam for a motor vehicle according to claim 1 , wherein the wheel air dam has an attachment section designed for attachment to a motor vehicle and a guide section designed to influence an airstream, wherein the sound-absorbing material forms at least one section of the guide section.

4. The wheel air dam for a motor vehicle according to claim 3 , wherein the guide section has a dam wall with a dam side, which when the wheel air dam is fully installed faces the front of the vehicle and during forward movement is impacted by the airflow, and with a shadow side opposite to the dam side, which when the wheel air dam is fully installed faces the rear of the vehicle, wherein at least the dam side of the guide section is made from the sound-absorbing material.

5. The wheel air dam for a motor vehicle according to claim 4 , wherein also the shadow side is made from the sound-absorbing material.

6. The wheel air dam for a motor vehicle according to claim 1 , wherein the wheel air dam is made completely from sound-absorbing material.

7. The wheel air dam for a motor vehicle according to claim 1 , wherein the sound-absorbing material forms two component surfaces that enclose an angle with one another.

8. The wheel air dam for a motor vehicle according to claim 1 , wherein the LWRT material is provided as a multilayer sandwich material.

9. A motor vehicle having a wheel air dam wherein at least one section of the wheel air dam comprises a sound-absorbing material, said wheel air dam being provided in the forward driving direction in front of the wheel of the motor vehicle on the underbody of the motor vehicle.

10. The motor vehicle according to claim 9 , wherein the wheel air dam has an attachment section designed for attachment to a motor vehicle and a guide section designed to influence an airstream, wherein the sound-absorbing material forms at least one section of the guide section; and at least the guide section is movable relative to the underbody of the motor vehicle, and in particular can be changed in its projection dimension from the underbody.

11. The wheel air dam according to claim 1 , wherein the sound-absorbing material forms more than two component surfaces that enclose an angle with one another.
