Abstract

A motor vehicle front end part ( 1 ) has a device for influencing a cooling air flow. The device has an adjustable flap ( 22 ) that extends in a vehicle transverse direction and that is assigned to an air inlet opening ( 10 ) with an air inlet cross section ( 12 ). To provide a motor vehicle front end part that is of simple design and can be produced cost-effectively, the flap ( 20 ) is arranged in front of the air inlet cross section ( 12 ) in a vehicle longitudinal direction to such an extent that, if the flap ( 20 ) is in an operative position, the cooling air flow ( 22, 23 ) is channeled completely or virtually completely past the air inlet opening ( 10 ).

First claim

What is claimed is:

1. A motor vehicle front end part having a lower part, an upper part spaced above the lower part so that an air inlet opening is defined between the upper and lower parts, the air inlet opening having an air inlet opening height extending vertically between the lower and upper parts, the upper part projecting more forward than the lower part, the motor vehicle front end part further having a device for influencing a cooling air flow, the device comprising an adjustable flap that extends in a vehicle transverse direction and that is in proximity to the air inlet opening, the flap being arranged at a lower surface of the upper part in front of the air inlet in a vehicle longitudinal direction by a distance greater than the air inlet opening height, the flap being positionable between an operative position in which the flap projects below the lower surface of the upper part and partly blocks the air inlet opening so that a cooling air flow is channeled past the air inlet opening and an inoperative position where the flap is substantially flush with the lower surface of the upper part so that the cooling air flow is not influenced by the flap.

2. The motor vehicle front end part of claim 1 , wherein the flap is smaller than the air inlet cross section.

3. The motor vehicle front end part of claim 1 , further comprising an air path and cooling air flaps that can close the air path.

4. The motor vehicle front end part of claim 3 , wherein the air inlet opening and the flap are arranged below the air path and the cooling air flaps.

5. The motor vehicle front end part of claim 1 , wherein the flap is mounted pivotally for movement about and axis that extends in the vehicle transverse direction.

6. The motor vehicle front end part of claim 5 , wherein the flap is mounted to pivot rearward when moving from the operative position to the inoperative position.

7. The motor vehicle front end part of claim 1 , wherein a height dimension of the flap in the operative position is no more than half of the air inlet opening height.

8. A motor vehicle having a motor vehicle front end part of claim 1 .

9. The motor vehicle front end part of claim 1 , further comprising a component to be cooled rearward of the upper part and above the lower part, the air inlet opening being forward of the component to be cooled and aligned at a same height position as a lower part of the component to be cooled.

10. The motor vehicle front end part of claim 9 , wherein the component to be cooled is a radiator.

11. The motor vehicle front end part of claim 10 , further comprising an air path at a position above the air inlet opening and cooling air flaps that can close the air path.

12. The motor vehicle front end part of claim 11 , wherein the air path is aligned at a same height as an upper part of the radiator.
