Abstract

An underbody panelling part of a wheel axle near the wheelhouse of a motor vehicle includes a substantially flat main part, a first mounting point provided on the main part, which first mounting point can be rotatably connected to a transverse link of the motor vehicle, and a second mounting point provided on the main part, which second mounting point can be coupled to a wheel carrier or a steering rod. The underbody panelling part can be pivoted about the first mounting point when the wheel carrier is pivoted. A subassembly having the underbody panelling part is also provided.

First claim

What is claimed is:

1. An underbody paneling part of a wheel axle in a region of a wheel arch of a motor vehicle, comprising:
a substantially plate-shaped main body having first and second bearing points formed thereon, wherein
the first bearing point is configured to be rotatably connected to a transverse link of the motor vehicle,
the second bearing point is configured to be coupleable to a wheel carrier or a steering rod of the motor vehicle,
the substantially plate-shaped main body is pivotable about the first bearing point with a pivoting movement of the wheel carrier of the motor vehicle.

2. A subassembly of a wheel axle of a motor vehicle, comprising:
an underbody panelling part having a substantially plate-shaped main body with first and second bearing points being formed on the substantially plate-shaped main body;
a transverse link of the motor vehicle;
a wheel carrier or a steering rod of the motor vehicle;
wherein the first bearing point of the substantially plate-shaped main body is rotatably connected to the transverse link of the motor vehicle and the second bearing point is coupled to the wheel carrier or the steering rod, and
wherein the underbody panelling part is pivotable about the first bearing point when the wheel carrier is pivoted.

3. The subassembly according to claim 2 , further comprising a pendulum rod connecting the second bearing point of the substantially plate-shaped main body to the wheel carrier or the steering rod.

4. The subassembly according to claim 3 , wherein the pendulum rod is mounted at both sides via ball joints.

5. The subassembly according to claim 2 , wherein the second bearing point is rigidly connected to the wheel carrier or the steering rod.

6. The subassembly according to claim 2 , wherein, at the first bearing point, a rotary joint is provided that connects the underbody panelling part to the transverse link.

7. The subassembly according to claim 6 , wherein the rotary joint is a sealed rotary plain bearing.

8. The subassembly according to claim 2 , further comprising a brush seal arranged to cover a gap between the underbody panelling part and an adjacent component.

9. The subassembly according to claim 2 , wherein the substantially plate-shaped main body has an upwardly curved edge arranged at a front end thereof in a longitudinal direction of the motor vehicle.

10. The subassembly according to claim 2 , wherein the underbody panelling part delimits, at an end thereof directed toward a rear end of the vehicle, an air duct oriented substantially horizontally.

11. The subassembly according to claim 10 , wherein the air duct is defined by a gap formed between the underbody panelling part and an adjacent vehicle body section.
