The present invention relates to a dual wheel structure for vehicles. In the dual wheel structure for vehicles, a leaf spring (20) is coupled in a lower part of a vehicle body frame (10). In a lower part of the leaf spring (20), an axle (40) with drums (30) in both ends thereof is coupled. The drums (30) are coupled in inner and outer wheel disks (61, 62) which are integrally welded in inner and outer wheel rims (51,52) as a double wheel rim (50), and outer protrusion parts (31) of the drums (30) are inserted into center holes of the inner and outer wheel disks (61,62) to be fixed. Both ends of the axle (40) are installed as passing through a hole of the drum (30) and holes of the inner and outer wheel disks (61,62). Also, in the inner wheel rim (51) and the outer wheel rim (52) as the double wheel rim (50), an inner wheel and an outer wheel of the vehicle are respectively mounted. In the present invention, there are significant effects that a double wheel is simply and stably installed in the vehicle double wheel rim, a contact area between the wheel and the ground increases to stably operate a vehicle, a loading capacity of a luggage compartment increases, and tire wear decreases. |
