Abstract: A hybrid component for lightweight, structural uses, including a steel member formed of a high strength steel; and a cast coupling member cast on a portion of the steel member by casting-in-place a semi-solid aluminum about the portion of the steel member, thereby positively and rigidly securing the coupling member to the steel member. A method of forming a hybrid component for lightweight, structural uses, including: forming a steel member formed of a high strength steel into a predetermined configuration; and casting a coupling member on a portion of the steel member by casting-in-place a semi-solid aluminum about the portion of the steel member, thereby positively and rigidly securing the coupling member to the steel member.

Abstract: A method of forming metal castings includes positioning a first end of a structural member in a first mold cavity and a second end of the structural member in a second mold cavity. The first and second mold cavities are fluidly coupled to a reservoir of molten metal. A main pressure is applied to the molten metal in the reservoir to force the molten metal into the first and second mold cavities. First and second auxiliary pressures are applied to the first and second mold cavities to densify the castings formed in the first and second mold cavities. Another method for casting includes maintaining a main pressure at or less than an initial, mold-filling pressure after the first and second mold cavities have been filled. Additionally, a method for detecting whether a first mold cavity is sufficiently filled with molten metal includes monitoring a moveable element.

Abstract: A motor vehicle frame includes a pair of longitudinal frame members. A cross member is provided to maintain the frame members in a spaced apart condition. The cross member has a first end configured to mount to a first one of the longitudinal frame members and a second end configured to engage a steering gear housing. The second end sandwiches steering gear housing as the second end is fastened to a second one of the frame members.

Abstract: A traditional twist beam axle found in a vehicle includes a twist beam with a separate torsion beam or a hollow tube formed into an inverted U shape that acts as both the twist beam and the torsion beam.
