Abstract
Disclosed are shear plates for structurally connecting vehicle chassis front cradles to battery pack support trays, methods for making and methods for using such shear plates, and electric vehicles with a chassis frame having a front cradle coupled to a battery pack support tray by a shear plate. A shear plate is disclosed for connecting a front cradle to a traction battery pack. The shear plate includes an elongated plate body with opposing fore and aft braces connected by opposing starboard and port braces. The fore brace directly mechanically couples to a cross member of the front cradle, whereas the aft brace directly mechanically couples to a support tray of the traction battery pack. The shear plate's elongated body is designed to transmit in-plane and torsional forces received from the front cradle via the fore brace, through the starboard and port braces, to the support tray via the aft brace.
