ABSTRACT:
A framing structure for the rear portion of an automotive, including a pair of spaced and generally vertically oriented suspension strut towers each tower fixed at lower and upper end portions to a lower cross beam and an upper cross beam respectively and with each cross beam extending the full width of the vehicle and with each beam having a closed cross-sectional configuration to providing a high degree of structural rigidity as a mounting platform for the left and right rear wheel suspensions. A yoke-like structure on the upper ends of each suspension strut tower supports an end portion of the upper cross beam, each yoke including a pair of spaced side walls between which an end portion of the beam extends so that in vehicle assembly the beam's end portions are positioned or floated in a respective yoke in sliding engagement between the spaced side walls which permits independent lateral shifting of the upper end portion of each strut tower into desired alignment with the vehicle and with one another. Subsequently, the overlying side walls of the strut towers are attached to the end portions of the cross beam by a plurality of widely spaced spot welds thus providing a high degree of rigidity and accuracy to the framing structure.
