Abstract

The present invention comprises an air flap arrangement (10) for a motor vehicle, comprising at least one air flap (16), an air flap carrier (12), on which the at least one air flap (16) is mounted rotatably about an air flap rotational axis (L), and a rotary drive (14), of which the torque-delivering drive shaft (32) is coupled to the at least one air flap (16) in a torque-transmitting manner, wherein a rotation angle limiting device is provided, which has a stop (38) secured to the air flap carrier and which has a counter-stop (28) that can be rotated with the at least one air flap (16), wherein the stop (38) and counter-stop (28), in a relative end position of the at least one air flap (16), are configured for contact engagement with one another, wherein the counter-stop (28) is configured on a counter-stop component (26) and an air flap face formation (20) is configured on an air flap component (18) configured separately from the counter-stop component (26), the counter-stop component (26) being formed of a material, which has a higher tensile strength than the material of the air flap component (18).

First claim

The invention claimed is:

1. Air flap arrangement or a motor vehicle, comprising:
at least one air flap;
an air flap carrier on which the at least one air flap is mounted rotatably about an air flap rotational axis;
and a rotary drive, of which the torque-delivering drive shaft is coupled to the at least one air flap in a torque-transmitting manner, wherein a rotation angle limiting device is provided, which has a stop secured to the air flap carrier and which has a counter-stop that can be rotated together with the at least one air flap, wherein the stop and counter-stop, in a relative end position of the at least one air flap relative to the air flap carrier, are configured for contact engagement with one another in such a way that when the contact engagement is produced, the at least one air flap can only still be moved in a rotational direction, which releases the contact engagement, relative to the air flap carrier, while a movement in a rotational direction opposing this release direction is not permitted;
wherein the counter-stop is formed on a counter-stop component and an air flap face formation, which frees or covers an air through-opening to a different extent for through-flow during operation, depending on the relative position of the air flap relative to the air flap carrier, is formed on an air flap component configured separately from the counter-stop component, the counter-stop component being formed of a material, which has a higher tensile strength than the material of the air flap component, wherein the counter-stop component has a first connection configuration for torque-transmitting connection to the drive shaft of the rotary drive and a second connection configuration for torque-transmitting connection to the air flap component, wherein the counter-stop is provided radially further out than the first and the second connection configuration.

2. Air flap arrangement according to claim 1 , wherein the material of the counter-stop component also has a higher modulus of elasticity than the material of the air flap component.

3. Air flap arrangement according to claim 1 , wherein the counter-stop component is made of polyamide.

4. Air flap arrangement according to claim 1 , wherein counter-stop component is formed of filled plastics material.

5. Air flap arrangement according to claim 1 , wherein the air flap component is formed of polyolefin.

6. Air flap arrangement according to claim 1 , wherein counter-stop is provided axially between the first and the second connection configuration.

7. Air flap arrangement according to claim 1 , wherein the first connection configuration can be inserted into the drive shaft or can be plugged onto the same or/and in that the second connection configuration can be inserted into a bearing formation, a bearing extension, of the air flap component or can be plugged onto the same.

8. Air flap arrangement according to claim 1 , wherein the air flap component is axially fixed on the counter-stop component.

9. Air flap arrangement according to claim 1 , wherein the rotary drive is arranged on one side of a portion of the carrier, and in that the air flap component is arranged on a side of this portion opposite thereto, the counter-stop component passing through the portion from one side to the other.

10. Air flap arrangement according to claim 3 , wherein the counter-stop component is made of PA66 polyester.

11. Air flap arrangement according to claim 3 , wherein the counter-stop component is made of polyethylene terephthalate or polyoxymethylene.

12. Air flap arrangement according to claim 5 , wherein the air flap component is fowled of polyolefin.

13. Air flap arrangement according to claim 5 , wherein the air flap component is formed of filled polyolefin.

14. Air flap arrangement according to claim 8 , wherein the air flap component is axially fixed on the counter-stop component.

15. Air flap arrangement according to claim 8 , wherein the air flap component is releasably fixed.

16. Air flap arrangement according to claim 9 , wherein the rotary drive is arranged on one side of a cheek or a wall of the carrier, and in that the air flap component is arranged on a side of this portion opposite thereto, the counter-stop component.

17. Air flap arrangement according to claim 9 , wherein the rotary drive is arranged on one side of a cheek or a wall of the carrier, and in that the air flap component is arranged on a side of this portion opposite thereto, passing through the portion from one side to the other.

18. Air flap arrangement according to claim 15 , wherein the air flap component is latched.
