12043058 · 2024-07-23 · ·

Wheels for use on vehicles and methods of manufacturing vehicle wheels are described in the present disclosure. According to one embodiment, a method includes a step of manufacturing a wheel that includes a rim, a center disk, and a plurality of spokes. The rim may include a substantially-cylindrical barrel adapted to seal a tubeless tire. The center disk may include a central bore adapted for engagement with an axle of a vehicle. Also, the plurality of spokes may be adapted to connect the center disk to the rim. The method further includes the step of deforming outwardly-facing surfaces of the spokes using one or more hammering or punching instruments.

A preparation method of shuttle spokes that includes these steps: providing a forging die comprising of an upper die and a lower die with the upper die and lower die having a joint angle of the shuttle spoke structure and an arch radius as well as a gap between the upper die and the lower die; inserting the blank of a round spoke into the gap between the upper die and lower die for stamping; using a plurality of nip molding rollers to eliminate the burr at both ends of the shuttle spoke structure; and applying a plurality of straightening rollers to straightness adjustment of the curved spoke body so that when the wheel parts are rolling, less air vortex can minimize air resistance.

Spinning process of magnesium alloy wheel hub

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.

HUBLESS ONE-PIECE WHEEL AND MANUFACTURING METHOD THEREFOR
20180229546 · 2018-08-16 ·

The present invention relates to a hubless one-piece wheel comprising: a rim; and a disc integrally formed at the rim and formed by low-pressure casting, wherein the disc is a hubless type including a plurality of spokes and a space at the center of the rim. One side of said each spoke is integrally formed at the rim, and a lug hole is formed in the other side of said each spoke for coupling the wheel to a vehicle body. The plurality of spokes are radially arranged inside the rim, and each of the other sides of the spoke locates in the inner center portion of the rim being separated by the space.
