A recently granted patent (Publication Number: US11919569B2) discloses a casting made of aluminum designed for use in motor vehicles. The casting includes a unique structure with upper and lower walls forming an H-shaped section transverse to a passage. Internal ribs within the H shape are strategically designed to compensate for height differentials in specific zones, ensuring structural integrity. The patent also details the configuration of the upper internal rib, external rib, and lower internal rib, emphasizing their roles in maintaining the overall shape and strength of the casting.

Furthermore, the patent describes additional features such as upper extensions, lateral parts of the lower internal rib, and cavities within the casting. These elements contribute to the overall stability and functionality of the casting, making it suitable for use as a lower part of a side member elbow in a motor vehicle's understructure. With a focus on precise measurements and specific design elements, the patented casting offers a novel solution for enhancing the structural components of motor vehicles, particularly in the context of side member elbows and understructure interfaces.
