Axis of a land vehicle, land vehicle with such a suspension and disk brake and brake support of such land vehicle
A land vehicle with a disk brake, in particular a utility vehicle with a disk brake, has an axle with a first and a second flange surface for flanging a brake carrier of the disk brake. A first through-opening opens into the first flange surface and a second through-opening opens into the second flange surface. The first through-opening in a first region has a smaller clearance width than in a second region. The first region is located closer to the first flange surface than the second region.
1. An axle of a land vehicle having a disk brake ( 12 ), the axle comprising
a first flange surface ( 32 ) and a second flange surface ( 34 ), for flanging a brake carrier ( 16 ) of the disk brake,

a second through-opening ( 30 ) which opens into the second flange surface,
wherein the first through-opening ( 28 ) in a first region ( 56 ) has a smaller first clearance width (W 1 ) than a second clearance width (W 2 ) in a second region ( 58 ), wherein the first region is located closer to the first flange surface ( 32 ) than the second region.
2. The axle as claimed in claim 1 , wherein the first region has a first axial length (L 1 ) and the second region has a second axial length (L 2 ), the second axial length (L 2 ) and the first axial length (L 1 ) having a length ratio of the second axial length (L 2 ) to the first axial length (L 1 ) of at least 1:1.
3. The axle as claimed in claim 2 , wherein the length ratio is at least 2:1.
4. The axle as claimed in claim 3 , wherein the length ratio is at least 4:1.
5. The axle as claimed in claim 1 , wherein the first clearance width (W 1 ) of the first region ( 56 ) is 0.30 mm to 2.8 mm smaller than the second clearance width (W 2 ) of the second region ( 58 ).
6. The axle as claimed in claim 5 , wherein the first clearance width (W 1 ) of the first region ( 56 ) is 0.40 mm to 0.55 mm smaller than the second clearance width (W 2 ) of the second region ( 58 ).
7. The axle as claimed in claim 6 , wherein the first clearance width (W 1 ) of the first region ( 56 ) is 0.45 mm to 0.55 mm smaller than the second clearance width (W 2 ) of the second region ( 58 ).
8. The axle as claimed in claim 1 , further comprising a sleeve ( 60 ) in the first region ( 56 ).
9. A land vehicle comprising
an axle ( 10 ) having
a first and a second flange surface ( 32 , 34 ) for flanging a brake carrier ( 16 ) of a disk brake,
a first through-opening ( 28 ) which opens into the first flange surface and
a second through-opening ( 30 ) which opens into the second flange surface,
wherein the first through-opening ( 28 ) in a first region ( 56 ) has a smaller first clearance width (W 1 ) than a second clearance width (W 2 ) in a second region ( 58 ) for the first through-opening ( 28 ), wherein the first region is located closer to the first flange surface ( 32 ) than the second region;
the disk brake ( 12 ) having the brake carrier ( 16 ), the brake carrier ( 16 ) of the disk brake having
a third flange surface ( 36 ) and a fourth flange surface ( 38 ) for flanging to the axle,
a third opening ( 40 ) which opens into the third flange surface ( 36 ) with an internal thread, and
a fourth opening ( 42 ) which opens into the fourth flange surface ( 38 ) with an internal thread,
a first screw ( 24 ) which in the mounted state extends through the first through-opening ( 28 ) into the third opening ( 40 ), and
a second screw ( 26 ) which in a mounted state extends through the second through-opening ( 30 ) into the fourth opening ( 42 ).
10. The land vehicle as claimed in claim 9 , wherein the first screw ( 24 ) and the second screw ( 26 ) are identical.
11. The land vehicle as claimed in claim 9 , wherein the third opening ( 40 ) in a first region has a smaller clearance width than in a second region, wherein the first region is located closer to the third flange surface ( 36 ) than the second region.
12. The land vehicle as claimed in claim 11 , wherein the first region has a first axial length (L 1 ) and the second region has a second axial length (L 2 ), the second axial length (L 2 ) and the first axial length (L 1 ) having a length ratio of the second axial length (L 2 ) to the first axial length (L 1 ) of at least 1:1.
13. The land vehicle as claimed in claim 12 , wherein the length ratio is at least 2:1.
14. The land vehicle as claimed in claim 13 , wherein the length ratio is at least 4:1.
15. The land vehicle as claimed in claim 11 , wherein the first clearance width (W 1 ) of the first region ( 56 ) is 0.30 mm to 2.8 mm smaller than the second clearance width (W 2 ) of the second region ( 58 ).
16. The land vehicle as claimed in claim 15 , wherein the first clearance width (W 1 ) of the first region ( 56 ) is 0.40 mm to 0.55 mm smaller than the second clearance width (W 2 ) of the second region ( 58 ).
17. The land vehicle as claimed in claim 16 , wherein the first clearance width (W 1 ) of the first region ( 56 ) is 0.45 mm to 0.55 mm smaller than the second clearance width (W 2 ) of the second region ( 58 ).
