The invention discloses a forged high-strength aluminum alloy wheel hub and a preparation method thereof. The wheel hub is characterized by comprising a wheel hub body, an inner bearing mounting surface, an outer bearing mounting surface, an oil seal mounting surface, a wheel connecting flange mounting surface, a brake disc connecting mounting surface, a half shaft or wheel hub end cover mountingsurface, a wheel spigot mounting surface, a half shaft or end cover bolt connecting thread, a tire bolt hole and a brake disc connecting bolt hole; the preparation method of the forged high-strength aluminum alloy wheel hub adopts a forging extrusion forming process and a post-forming heat treatment process; an aluminum bar profile is formed in a forging and extruding production mode, and after forming, the finished aluminum hub is formed through heat treatment and machining. The invention aims to adapt to the development trend of light weight, energy conservation and emission reduction of automobiles, and solves the problems of many defects, low strength, poor rigidity and easiness in fragmentation of cast aluminum hubs of automobiles. The problem that an automobile casting ductile iron hub is heavy is solved. The problem of environmental pollution in the existing hub production process is solved.
