A bumper system including a bumper beam being cast from metal having a front panel and a back panel, extending between a first bumper beam end and a second bumper beam end. A plurality of reinforcing ribs integrally cast with the bumper beam extends between the front panel and the back panel defining a non-uniform cross-sectional profile along a portion of the bumper beam. The front panel includes a front center portion disposed between a pair of front side portions. The back panel includes a back center portion disposed between a pair of back side portions. The front center portion has a front center portion thickness greater than a back center portion thickness. Each of the front side portions has a front side portion thickness being less than a back side portion thickness of adjacent one of the back side portions. Method of manufacturing the bumper system is provided.

Cast bumper system and method of manufacturing same

A bumper beam includes an outer portion and an inner portion each extending between a top end and a bottom end. At least one of the outer portion or the inner portion includes a pair of geometrical features each of which are disposed in spaced relationship to one another and adjacent a respective one of the top or bottom ends. A top wall and a bottom wall each extend from one of the geometrical features to the other of the outer portion or the inner portion to interconnect the outer and inner portions of the bumper beam. The geometrical features can be varied in size and shape to change and tune the energy absorption properties of the bumper beam and ultimately provide for a bumper beam that is adaptable and flexible over a range of vehicle applications.

Bumper beam

A vehicle bumper assembly includes a bumper beam and a crash box. At least one of the bumper beam or the crash box is cast from metal, such as aluminum or magnesium, to reduce weight, reduce manufacturing process steps, and improve performance characteristics of the bumper assembly. In an embodiment, both of the bumper beam and the crash box are cast from metal to establish an integral connection therebetween. One of the bumper beam or the crash box can be open along a top and bottom portion of the bumper assembly and include at least one reinforcing rib cast integral therewith. In an embodiment, both of the bumper beam and the crash box can be open along a top and bottom portion of the bumper assembly and each include at least one reinforcing rib cast integral therewith.

Cast bumper assembly and method of manufacturing same

A bumper beam system is provided that includes a bumper beam that is cast from metal and has at least a first portion comprised of a first alloy and a second portion comprised of a second alloy that is different than the first alloy. Furthermore, a crash box is provided that comprises a first portion comprised of a first alloy and a second portion comprised of a second alloy that is different than the first alloy. Additionally, a bumper beam system is provided that has a bumper beam and a crash box. The bumper beam includes at least a first bumper beam portion that is comprised of a first bumper beam alloy, and the crash box includes at least a first crash box portion that is comprised of a first crash box alloy. Methods of manufacturing the bumper beam system and crash boxes are also provided.

A hybrid torsion beam axle assembly is provided, which includes a steel torsion beam. An end cap is fastened to an end portion of the steel torsion beam, and a cast trailing arm is cast about the end portion of the steel torsion beam including the end cap. In this way, the cast trailing arm is positively and rigidly secured to the steel torsion beam.

Hybrid component

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.

A bumper system for mounting to a frame assembly of a motor vehicle at one end of the motor vehicle includes a bumper beam and an energy absorber. The bumper beam includes an upper beam wall, a lower beam wall, and a central beam wall between the upper and lower beam walls. The energy absorber is mounted to the bumper beam and includes an upper absorber wall, a lower absorber wall, and a central absorber wall between the upper and lower absorber walls. The energy absorber has a height that is greater than a height of the bumper beam such that the upper absorber wall is spaced upwardly above the upper beam wall and the lower absorber wall is spaced downwardly below the lower beam wall.
