  • Wheel for vehicles and method for producing the same
    Publication number: 20100045095
    Abstract: A wheel for a vehicle including an outer rim and an inner rim, in which the outer rim is comprised of a disk section formed by embossing a first portion having a certain thickness and a rim section formed by drawing a second portion having a smaller thickness than the first portion so as to make a periphery of the disk section; and the inner rim is comprised of superimposed portions formed by drawing and to be superimposed on prescribed positions of the disk section of the outer rim. Flange sections of the outer and inner rims are respectively inwardly curled so as to form a double-layered structure. The outer and inner rims are integrated by welding with the superimposed portions set at the prescribed positions of the disk section.

  • Vehicle wheel
    Patent number: 7290838
    Abstract: A vehicle wheel comprises a rim (172) and a disk section (171) separate from the rim. Since the disk section is separate from the rim, the freedom of designing the disk section is improved. The rim comprises an outer rim (178) and an inner rim (181) separate from the outer rim. The outer and inner rims are attached to the outer periphery of the disk section at the same place by welding.

  • Wheel for vehicle
    Patent number: 6340210
    Abstract: A wheel for a vehicle comprises first and second wheel halves joined together, and a center plate being generally cross-shaped. Each wheel half has a disk portion and a rim continuing from the disk portion. The center plate is inter-posed between the disk portions and has a diameter smaller than an outside diameter of each of the disk portions. The first and second wheel halves and the center plate are unitarily connected together by means of a plurality of sockets each having a countersunk head and a cylindrical shank. This arrangement increases freedom of design of the wheel and facilitates production of the same.
