Abstract:
The apparatus includes a first component mounted for rotation with the wheel and a second component spaced from the first component by a predetermined gap and not connected for rotation with the wheel. One of the first and the second components is displaced relative to the other upon a force to close the gap and contact the other component to form a load path for the force. The load path is a secondary load path that bypasses the bearing races, preventing excessive plastic deformation of the races. The apparatus is configured with at least one feature to inhibit corrosion of the first and second components at the gap. The feature may be an extension of the second component that localizes the gap to just a portion of the second component. Alternatively, coatings, shims, lubricants, and seals may be used alone or in combination to prevent corrosion at the gap.
