Abstract
The disc has a shallow cup shape and the spot welds are made between the outer surface of the cup wall, and the bore of the smallest dia. of the profiled rim. One or more indentations are made on >=1 external surface of the outer surface and bore zones, i.e. not the joint surfaces. Each indentation has a depth less than the thickness of the metal sheet from which the rim and disc are made, and the indentations do not deform the joint surfaces. The min. distance between the centre of each indentation and the centre of the nearest spot weld is pref. 0.7-1 times the dia. of the spot weld. The indentations are designed to reinforce the wheel by a simple and inexpensive method.
