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.

Hubless one-piece wheel and manufacturing method therefor

The present invention relates to a vertical centrifugal casting device comprising: an installation frame including a rotary table; a rotation table bearing-coupled to the rotary table so as to be rotated by the operation of a driving means; a supply connection means; rotation-preventing equipment; a mold part; a side mold fixing means; an upper mold fixing means; a connection fixing part; a lifting means; and an ejector means coupled to the lifting frame of the lifting means so as to eject a molded product.

Vertical centrifugal casting device

The present invention relates to a wheel having a rim portion including an air-tight rim formed in a cylindrical shape, and a protruded grid portion having a plurality of first recesses by being protruded from and equally spaced around the circumference of the air-tight rim. In this way, the honeycomb rim-type wheel can be readily manufactured to have lightweight using a single casting without sacrificing durability thanks to the protruded grid portion on the circumference of the air-tight rim, thereby reducing time and cost for manufacturing by reduced usage of molten metal.
