Abstract
A base plate having a hub, a flange having an outer flange region at an outer periphery of the flange and a clamping region at an inner periphery of the flange that is contiguous with the hub. The flange has a modified region that at least partially surrounds and is contiguous with the clamping region, the modified region having a stress reducing configuration such that the clamping region is thicker than the outer flange region. The modified region may be a circular or linear step, and can be on either side of the flange. The step fits the contour of a load beam and the flange is welded to the load beam. The load beam thickness is the same as or less than the thickness of the step.
