Rim well with integrated flange made of fiber composites as well as method for manufacturing same
A rim well with integrated flange made of fiber composite as well as to a method for manufacturing same. The flange is formed by inwardly directed protuberances of fiber layers of the rim well, wherein the fiber layers transition to the flange from the rim well without interruption of the fibers. The manufacture is carried out by depositing fiber material on a mold, which corresponds to the contour of the rim well and has a radially circumferential or segmented groove. The fibers are deposited such that the fibers of at least one fiber layer have protuberances directed into the groove. A multipart mold, which makes it possible to reduce the width of the groove and thus a deformation of the protuberances, is preferably used.

the fibers of the flange-forming fiber layers have an angle of ±3° to ±87° relative to the axial direction of the rim well; and
the fibers of the rim well-forming fiber layers have a fiber angle of ±3° to ±87°, relative to the axial direction of the rim well.
9. A rim well made of fiber composite in accordance with claim 1 , comprising semifinished textile products with fiber orientations ranging from ±0° to ±90° relative to the axial direction of the rim well.
10. A rim well made of fiber composite in accordance with claim 1 , wherein the flange is circumferential or is in the form of individual circle segments on the inner side of the rim well.
11. A rim well made of fiber composite in accordance with claim 1 , wherein inlays in the form of a broken ring or individual circle segments are embedded in the protuberances of the flange.
12. A rim well made of fiber composite in accordance with claim 1 , wherein the flange has a rectangular geometry with straight flanks or a V-shaped geometry with oblique flanks.
13. A rim well made of fiber composite in accordance with claim 1 , wherein a layer of fiber layers of the rim well, which layer is located radially outside, or textile patches applied additionally in the area of the protuberances having no fibers entering the flange.
14. A rim well, comprising:
a rim well structure comprising fiber layers, a first rim well portion, a second rim well portion and a flange, said flange being located on an inner side of said rim well structure for fastening a wheel spider or a wheel disk, wherein a portion of said fiber layers extend continuously, without interruption, from said rim well first portion to said inner flange and another portion of said fiber layers extend continuously, without interruption, from said inner flange to said rim well second portion.
15. A rim well in accordance with claim 14 , wherein said first rim well portion comprises a first rim well portion outer surface for engaging a portion of a tire, said second rim well portion comprising a second rim well portion outer surface for engaging another portion of the tire, wherein said first rim well portion, said second rim well portion and said flange are formed of said fiber layers.
16. A rim well in accordance with claim 15 , wherein said flange extends in an inward direction, away from said first rim well portion and said second rim well portion, said fiber layers extending continuously, without interruption, from one side of said rim well structure to another side of said rim well structure.
17. A rim well in accordance with claim 14 , wherein said fiber layers are formed from braided continuous filaments.
18. A rim well in accordance with claim 14 , wherein said flange is circumferential or is in a form of individual circle segments on the inner side of the rim well.
19. A rim well, comprising:
a rim well structure formed of composite fiber, said composite fiber comprising fiber layers, said rim well structure comprising an inner side, a flange and an outer tire engaging surface for engaging a tire, said flange extending from said inner side in a direction away from said outer tire engaging surface for fastening a wheel disk or a wheel spider, said fiber layers extending continuously, without interruption, from one side of said rim well structure to another side of said rim well structure, wherein at least a portion of said fiber layers form said flange.
