The invention discloses a wheel hub forged piece structure for a motor vehicle. The wheel hub forged piece structure for the motor vehicle comprises a wheel hub body. The wheel hub body comprises a wheel disk, a wheel rim and a wheel rim outer ring, wherein a steel tube part is arranged in the middle of the wheel hub body in a fusion combination mode. The wheel hub forged piece structure is characterized in that a plurality of protruding portions are arranged on the periphery of a wheel hub body forged piece, chamfers are arranged at the ends of the protruding portions, and the chamfers and the protruding portions are connected through circular-arc sections. According to the wheel hub forged piece structure for the motor vehicle, due to the fact that the steel tube part is arranged in the middle of the wheel hub body in the fusion combination mode, the situation that relative rotation between the steel tube part and the wheel hub body cannot happen can be guaranteed, the strength of a wheel hub can be high, and the service life can be long; due to the fact that the chamfers are manufactured on the top of the trimmed portion of the forged piece, and connected through inverted circular arcs, the consistency of products is enhanced, the product quality is improved, trimming burrs of the products are effectively avoided, and the production efficiency is improved.
