The wheel disc 54 is cast, forged, fabricated or otherwise formed from a suitable material, such as for example, steel, aluminum or alloys thereof, steel, magnesium, or titanium. The wheel disc 54 includes a generally centrally located wheel mounting portion 70 and an outer annular portion 72. The wheel mounting portion 70 includes a center hub hole 74 and a plurality of lug bolt mounting holes 76 (one of such lug bolt mounting holes 76 illustrated in
The outer annular portion 72 of the wheel disc 54 defines a wheel disc outer annular leg or flange, indicated generally at 80. As best shown in
In the illustrated embodiment, each of the first segments 82 extends a first circumferential distance or angular extent C1. The first distance C1 is preferably in the range from about 45 degrees to about 75 degrees. More preferably, the first distance C1 is in the range from about 55 degrees to about 65 degrees. In the illustrated embodiment, the first distance C1 is approximately about 60 degrees.
Each first segment 82 includes a generally axially extending outer side surface 82A, a generally axially extending inner side surface 82B, and a generally radially extending end surface 82C. Typically, the outer side surface 82A of the first segment 82 of the wheel disc 54 is oriented at a predetermined angle A1, shown in
In the illustrated embodiment, the end surface 82C of each of the first segments 82 extends a first axial distance D1, as shown in

In the illustrated embodiment for a purpose to be discussed below, the second axial distance D2 is less then the first axial distance D1 so that the second flange F2 of each of the second segments 84 is shorter than the first flange F1 of each of the first segments 82. Alternatively, the configuration, spacing, angular extent and/or the number of any one of the plurality of the second segments 84 may be other than illustrated if so desired. In addition, while this embodiment discloses two different segments 82 and 84 about the flange 80 the flange 80 may include more than two different segments if so desired.
To secure the wheel disc 54 to the wheel rim 52, the wheel rim 52 is preferably held stationary and the wheel disc 54 is inserted therein to a predetermined position and then is welded to produce the finished vehicle wheel 50. Preferably, during the insertion of the wheel disc 54 to the predetermined position, the wheel disc 54 is inserted until the wheel disc 54 is inserted to a predetermined position within the wheel rim 52, or until the end surfaces 82C of the first segments 82 of the flange 80 engage or “bottom out” on the inner surface 66A of an angled sidewall 66 of the well 60 of the wheel rim 52. Once the wheel disc 54 has been inserted to the predetermined position, welds 88 are provided in each of the second segments 84 at the interface between the end surfaces 84C thereof and an adjacent inner surface 62A of the bead seat 62 of the wheel rim 52 to secure the wheel disc 54 and the wheel rim 52 together and produce the fabricated bead seat attached vehicle wheel 50 shown in this embodiment. The welds 88 may be of any suitable type, such as for example, gas metal arc welds. Alternatively, the relative movement and/or fixation of the wheel rim 52 and the wheel disc 54 may be other than illustrated if so desired. In addition, if desired, one or more suitable welds could be provided at the first flange Fl of one or more of the first segments 82. Suitable welds at the first flange Fl may include, for example, laser welds and e-beam welds.
