The invention discloses an aluminum alloy automobile hub, which comprises a disc (1), wherein the disc (1) comprises a rim (11) and a wheel center (13). The aluminum alloy automobile hub is characterized in that five radial wheel disks (12) are circumferentially and uniformly arranged between the rim (11) and the wheel center (13), wherein two symmetric rib plates (121) are arranged on the upper surface of each radial wheel disk (12); a small trapezoidal hole (122) is formed in the side, close to the rim (11), of each wheel disk between the corresponding two rib plates (121), and a large trapezoidal hole (123) is formed in the side, close to the wheel center (13), of each wheel disk between the corresponding two rib plates (121); five rectangular bumps (131) are circumferentially and uniformly arranged on the wheel center (13). The aluminum alloy automobile hub is novel in structure, the flowability of molten aluminum during casting can be remarkably improved, and the casting defects of the wheel disks can be completely eliminated.
