According to a wheel in which a heterogeneous material is inserted, which is presented by the present invention, provided is a structure in which a ring-shaped auxiliary wheel comprising a metallic material can be inserted into and coupled to the central outer diameter of the outer circumferential surface of a main wheel comprising a plastic material, and thus a metallic heterogeneous material is inserted into a wheel, thereby increasing a rotation speed due to a local mass increase at the same volume by using the difference in specific gravity (density). In addition, according to the present invention, it is possible to facilitate the variation of mass under the same conditions as a known structure of a single material through the difference in specific gravity (density) between the main wheel and the auxiliary wheel, thereby further improving driving performance. |
