a main body ( 12 ), and
at least one reinforcing structure ( 14 ) for increasing a strength of the wheel ( 10 ),
wherein the reinforcing structure ( 14 ) is at least partially integrally cast in the main body ( 12 ), and
wherein the reinforcing structure ( 14 ) is prestressed under a pretensile stress serving to increase a compressive strength.
2. The wheel as claimed in claim 1 , wherein the main body ( 12 ) has a nave component ( 16 ) and a blade component ( 18 ), the reinforcing structure ( 14 ) being arranged in the nave component ( 16 ) and/or in the blade component ( 18 ).
3. The wheel as claimed in claim 1 , wherein the reinforcing structure ( 14 ) takes the form of a prefabricated reinforcing element ( 20 ).
4. The wheel as claimed in claim 3 , wherein the reinforcing element ( 20 ) takes the form of a strengthening tube ( 22 ), which is integrated in the nave component ( 16 ) of the wheel ( 10 ).
5. The wheel as claimed in claim 1 , wherein the reinforcing structure ( 14 ) has a multiplicity of reinforcing fibers ( 38 ) freely distributed in the main body ( 12 ).
6. The wheel as claimed in claim 1 , wherein the reinforcing structure ( 14 ) has high-strength metal fibers and/or carbon fibers and/or glass fibers.
7. The wheel as claimed in claim 1 , wherein the main body ( 12 ) is manufactured using aluminum as basic material.
8. The wheel as claimed in claim 1 , wherein the wheel is a compressor wheel and in particular a compressor wheel for an exhaust-gas turbocharger of a motor vehicle.
9. A wheel ( 10 ), comprising:
a main body ( 12 ), and
at least one reinforcing structure ( 14 ) for increasing a strength of the wheel ( 10 ),
wherein the reinforcing structure ( 14 ) is at least partially integrated inside the main body ( 12 ),
wherein the reinforcing structure ( 14 ) is prestressed under a pretensile stress serving to increase a compressive strength, and
wherein the reinforcing structure ( 14 ) has a mesh inlay ( 24 ).
10. The wheel as claimed in claim 9 , wherein the mesh inlay ( 24 ) comprises a plurality of mesh components ( 26 , 28 , 30 ) extending in a radial direction and/or in an axial direction and/or in a peripheral direction in relation to the wheel ( 10 ).
11. The wheel as claimed in claim 9 , wherein the mesh inlay ( 24 ) is arranged, at least in part, immediately below the surface ( 31 ) of the main body ( 12 ).
12. The wheel as claimed in claim 9 , wherein the mesh inlay ( 24 ) is arranged at least partially at the surface ( 31 ) of the main body ( 12 ).
13. A wheel ( 10 ), comprising:
a main body ( 12 ), and
at least one reinforcing structure ( 14 ) for increasing a strength of the wheel ( 10 ),
wherein the reinforcing structure ( 14 ) is at least partially integrated inside the main body ( 12 ),
wherein the reinforcing structure ( 14 ) is prestressed under a pretensile stress serving to increase a compressive strength, and
wherein the reinforcing structure ( 14 ) additionally has a reinforcing component ( 32 ) arranged entirely externally in relation to the main body ( 12 ) and fixed thereto.
14. The wheel as claimed in claim 13 , wherein the external reinforcing component ( 32 ), as a stiffening element ( 34 ) at least partially reproducing the blade geometry, is provided with an at least partially integrated inlay structure ( 36 ).
15. The wheel as claimed in claim 13 , wherein the external reinforcing component ( 32 ) takes the form of a high-strength circular banding unit.
