Vehicle frames are foundational structural components, typically constructed from steel or aluminum, to which all other vehicle systems are mounted. They provide rigidity and impact absorption, ensuring vehicle stability and occupant safety. Frame designs vary – including ladder, unibody, and space frame – each optimized for specific vehicle types and performance characteristics. Critical features include strategically placed crossmembers, reinforced sections, and mounting points designed to withstand substantial loads and stresses. Frame integrity is paramount for proper vehicle alignment, handling, and crashworthiness.
