Air flap arrangement with a separate stop component
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 ).
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.
