Material Science Advancements
Truck steel plates (e.g., chassis steel, leaf springs) commonly use high-carbon alloy steel (e.g., 60Si2MnA, QSTE series) or hot-formed boron steel, with tensile strength exceeding 1000 MPa and yield strength over 700 MPa. For example, a single leaf spring can withstand 5-10 tons of dynamic load, and multi-layer stacking designs easily handle impacts from heavy loads and rough terrains.
Lightweight Design
Laser cutting and variable cross-section rolling reduce weight while maintaining strength. For instance, replacing traditional materials with high-strength steel in chassis reduces weight by 15%, lowering fuel consumption (saving ~1.5L/100km) and increasing payload capacity.
Smart Design & Scenario Adaptability
Dynamic Adaptability
Leaf springs use primary-secondary staging: primary springs handle light loads (improving ride comfort), while secondary springs engage under heavy loads (enhancing capacity). Parabolic tapered-leaf designs boost shock absorption efficiency by 20%.
Modular Expandability
Standardized chassis holes and splicing designs allow quick adaptation to cargo boxes, lifting equipment, or EV battery packs, meeting diverse needs like cold-chain and hazardous material transport.
