Abstract
A wheel for vehicles may include a rim coupled to a tire, and a spoke-shaped disc including a spoke and a vent hole, the spoke-shaped disc being coupled to a side surface of the rim to support the rim, in which a coupling zone between the spoke of the spoke-shaped disc and the rim and a coupling zone between a portion of the spoke-shaped disc formed with the vent hole and the rim have a height difference in a wheel axis direction, to allow the spoke-shaped disc to support the rim at an interior and an exterior of the rim.
Claims6
1-4. (canceled)
5:
- A method for manufacturing a wheel for vehicles, the method comprising:
- forming a rim configured to be coupled to a tire and a spoke-shaped disc including a spoke and a vent hole;
- and
- coupling the spoke-shaped disc to a side surface of the rim such that a coupling zone between the spoke of the spoke-shaped disc and the rim and a coupling zone between a portion of the spoke-shaped disc formed with the vent hole and the rim have a height difference in a wheel axis direction, to allow the spoke-shaped disc to support the rim at an interior and an exterior of the rim.
1 more element
6:
- The method of claim 5, wherein an end of the spoke of a peripheral portion of the spoke-shaped disc is coupled to an exterior position of the rim, and a vent hole position end, corresponding to an end of the portion formed with the vent hole, of the peripheral portion of the spoke-shaped disc is coupled to an interior position of the rim.
7:
- The method of claim 5, wherein an end of the spoke and the portion formed with the vent hole are coupled, via welding, to positions of the rim having a height difference in the wheel axis direction.
8:
- The method of claim 6, wherein the end of the spoke and the portion formed with the vent hole are coupled, via welding, to positions of the rim having a height difference in the wheel axis direction.
9:
- The method of claim 5, wherein, after the rim is formed of steel and the spoke-shaped disc is formed by pressing a steel panel, the rim and the spoke-shaped disc are coupled to each other to complete a styled steel wheel.
