Air guiding device of a motor vehicle body of a motor vehicle
View Patent ↗An air guiding device of a motor vehicle body of a motor vehicle includes a slat assembly. The slat assembly includes at least two slats, which are arranged so as to be borne rotatably about their axis of rotation in a frame of the air guiding device, and wherein, for rotation about the axis of rotation, the slat has a first bearing point and a second bearing point configured so as to lie opposite the first bearing point. For the rotatable bearing in the frame, the first bearing point of a first coupling point of the frame and the second bearing point of a second coupling point of the frame are arranged opposite one another. The slat is configured so as to absorb tensile and compressive forces.
1 . An air guiding device of a motor vehicle body of a motor vehicle, said air guiding device comprising:
a slat assembly comprising at least two slats, each slat being arranged so as to be rotatable about an axis of rotation in a frame of the air guiding device,
wherein, each slat has a first bearing point and a second bearing point lying opposite the first bearing point,
wherein a first coupling point of the frame and a second coupling point of the frame are arranged opposite one another, wherein the first and second bearing points lie opposite the first and second coupling points, respectively,
wherein each slat is configured to absorb tensile or compressive forces, wherein, in order to transmit the tensile or compressive forces between the slat and the frame, at least one of the bearing points of a first slat of the at least two slats comprises a first means for absorbing the compressive or tensile forces, wherein the first means comprises a bearing pin and a landing disposed on the first slat that extends along the longitudinal axis of the first slat and about the bearing pin,
wherein a bearing element in the form of a sliding bearing bushing is disposed between the first means and the frame, wherein the bearing element includes an opening that receives the bearing pin of the first slat,
wherein the landing is positioned to face the sliding bearing bushing, and
wherein the sliding bearing bushing extends in a radial direction beyond a perimeter of the landing.
2 . The air guiding device according to claim 1 , further comprising a gap extending along the longitudinal axis, the gap being located either (i) between the first means and the frame or (ii) between the first means and the bearing element.
3 . The air guiding device according to claim 1 , wherein the first means is covered entirely in a radial direction by either the frame or the bearing element.
4 . The air guiding device according to claim 1 , further comprising a linear contact between the first means and either the frame or the bearing element.
5 . The air guiding device according to claim 1 , further comprising a detent connection disposed between the first slat and the frame for absorbing tensile forces between the first slat and the frame.
6 . The air guiding device according to claim 5 , wherein the detent connection comprises an undercut formed on the first slat.
7 . The air guiding device according to claim 1 , further comprising a screw, a split, a plug, a nut or a locking washer that is configured to bring about at least a positive lock with the first slat.
8 . The air guiding device according to claim 1 , wherein the first slat or the frame is configured so as to be elastically deformable.
9 . A motor vehicle comprising the air guiding device of claim 1 .
10 . The air guiding device according to claim 1 , wherein the landing is formed on a free end of the first slat that faces the frame, and wherein the landing has a reduced wall thickness on the free end.
11 . The air guiding device according to claim 10 , wherein the bearing pin extends outwardly from the free end of the first slat.
12 . The air guiding device according to claim 1 , wherein the sliding bearing bushing is sandwiched in a radial direction between the bearing pin and the frame.
13 . The air guiding device according to claim 1 , wherein the sliding bearing bushing is sandwiched in an axial direction between the landing and the frame.
14 . The air guiding device according to claim 1 , wherein at least a portion of the bearing pin and the sliding bearing are disposed within a circular opening formed in the frame.
15 . The air guiding device according to claim 14 , wherein a free end of the bearing pin includes a detent that is configured to positively engage with a surface disposed on the circular opening of the frame for retaining the first slat to the frame.
16 . The air guiding device according to claim 14 , further comprising a spring element extending within the circular opening of the frame, wherein the spring element is configured to positively engage with a surface disposed on a free end of the bearing pin for retaining the first slat to the frame.
