FIELD: transport. ^ SUBSTANCE: proposed wheel comprises rim 1, hub 2 and disk 3 with outer 4 and inner 5 curvilinear surfaces. Central line 6 of radial rim cross section is displaced along wheel axis 7 relative to central line 8 of hub radial cross section toward outer curvilinear surface 4. Generatrix of outer curvilinear surface 4 consists of at least two connecting outer curves (R1, R2) with opposed direction curvature. First outer curve Ri fairs with rim 1 by first outer transition section R4. Second outer curve R2 fairs with hub 2 by second outer transition section R5. Generatrix of inner curvilinear surface 5 consists of at least one of inner curves (R3) that fairs with rim1 by first inner transition section R4 and, with hub 2, by second inner transition section R7. Central line 9 of the disk radial cross section at the point of connection with hub 2 is displaced along wheel axis 7 relative to central line 8 of the hub radial cross section toward inner curvilinear surface 5 for distance S1 varying from 10 to 30 mm. Point A of connection between first outer curve R1 and second outer curve R2 is spaced from wheel axis 7 by L1=0.32-0.35 of wheel rolling circumference diametre. Point B of connection between generatrix of inner curvilinear surface 5 and first inner transition section R6 is spaced from wheel axis 7 by L2=0.33-0.36 of wheel rolling circumference. ^ EFFECT: reduced wheel total inner strains. ^ 3 dwg |
