6.2.3 Wheel rim
Note
We are all used to talking about discs, about whether they are cast or forged - what are their markings. In fact, speaking of disks, we have always, even without knowing it, meant exactly the wheel, which includes a rim and a disk in its structure.
The wheel is usually mounted on a hub, which, in turn, is placed in a steering knuckle and rotates freely on roller bearings. A wheel is made out of sheet metal by stamping and subsequent welding of elements. Wheels can be cast from light-alloy materials (for example, aluminum and magnesium alloy), or they can be forged, which combine light alloy-material and stamping. Also, there are disc and discless wheels (remember the "unique" solution of such a wheel of the well-known "Tavria").
