초록

An engine cradle is formed from tubular stock material using mechanical bending and hydroforming techniques. To facilitate connections with the body and frame assembly of the vehicle, hollow end portions of the engine cradle are subjected to an end forming operation. The result of the end forming operation is that the hollow end region of the engine cradle is deformed to have a generally U-shaped cross section having an aperture formed therethrough. The central portion of the U-shaped end region is flat so as to facilitate the connection of the engine cr...
