GAP JOINT FOR CLOSED SECTION LOAD TRANSFER.

摘要

A hydro-formed body side rail is assembled by a bracket to a front header. The front header is an extruded cross-car structural support that is joined to the body side rail by a framed joint. A gap is defined between the body side outer panel and the hydro-formed side rail relative to a lateral end of a front header. Side impact test loads are applied initially to the body side rail and compress the bracket. Compression of the bracket closes the gap and the impact loads are applied to the cross-car structural support.
