摘要： A system and method of manufacturing an aluminum fuel cell cradle includes providing a negative cast mold having cavities to form the cradle and providing a feeding mechanism disposed about the mold and in fluid communication with the cavities thereof. The feeding mechanism includes a plurality of primary risers connected to and in fluid communication with cavities. The method further includes melting a first metallic material to define a molten metallic material, and moving the mold to a vertical casting orientation about a rotational axis, while feeding molten metallic material through the runner to the cavities, and cooling the molten metallic material to define a solidified metallic material. A second solidification time in the risers is greater than a first solidification time in the mold such that shrinkage of the solidified metallic material occurs in the risers away from the mold.

摘要： In at least some implementations, a system for a vehicle differential that has multiple gears may include a coil, a drive member movable in response to a magnetic field generated by application of electricity to the coil and a lock member driven by the drive member to selectively engage a gear of the differential. The drive member is movable between a first position and a second position, has an axis and includes a first body formed at least partially from a first material that is magnetically responsive and a second body formed at least partially from a second material. The first body and second body are coupled together and overlapped in two opposing axial directions to limit or prevent relative axial movement between the first body and the second body.
