Abstract: A structural element having two opposed and parallel U-shaped members opening toward one another with a web of elongated corrugated form extending between the first and second U-shaped members. The web has a first set of coplanar flats fixed to opposed coplanar first sides of the two U-shaped members and a second set of coplanar flats fixed to opposed coplanar second sides of the two U-shaped members. The first coplanar flats alternate with and are joined to the second coplanar flats by secondary flats which have stepped relief cutouts and are spaced apart from the U-shaped members.

Abstract: The present invention relates to an improved independent suspension system for vehicle wheels which may be used either for driven or non-driven wheels including dirigible wheels of a vehicle having front wheel drive. One of the independently suspended driven wheels is mounted on an end of a transversely extending stamped metal suspension arm pivoted about the other end for movement relative to a point on the vehicle chassis. The other driven wheel is mounted on a second transversely extending stamped metal suspension arm which also is pivoted for movement relative to a point on the vehicle chassis. The second arm mounts a differential which is connected through axle shafts to drive the wheels.
