Abstract: The disclosure discloses a spinning process of a magnesium alloy wheel hub, which comprises the following steps: step 1, heating a magnesium alloy bar at 350-430° C. and keeping the temperature for 20 minutes; step 2, initially forging and forming on the bar under a forging press, wherein the forging down-pressing speed is 6-15 mm/s; step 3, finally forging and forming on the bar under a forging press, wherein the forging down-pressing speed is 5-8 mm/s; step 4, stress relief annealing on the final forged magnesium alloy blank; step 5, solid dissolving on the annealed magnesium alloy blank; step 6, taking out the solid-dissolved blank and directly spinning by a spinning machine; step 7, heating treatment and aging treatment. The magnesium alloy wheel hub with excellent performance is obtained by the process, and the spinning process and processing efficiency are greatly improved.

Abstract: The invention discloses a non-pneumatic tire, comprising a wheel hub; an annular belt located on the periphery of the wheel hub; spokes comprising a plurality of spokes circumferentially arranged between the annular belt and the wheel hub; each spoke being V-shaped, and the spoke comprising two inclined plates arranged at an angle and an arc-shaped apex corner area formed at the joint of the two inclined plates; a resistance part for limiting the deformation amount of the apex corner area to a deformation amount corresponding to the yield strength. According to the invention, plastic permanent deformation of spokes can be effectively avoided by adding resistance parts, and further the service life of non-pneumatic tires can be prolonged.
