Heavy-duty trucks and trailers are the backbone of global transportation, enabling the movement of goods across vast distances and through challenging terrains. These vehicles are designed to handle massive loads and endure rigorous operational demands, from highways to construction sites and off-road environments. One critical aspect of heavy-duty vehicles that is often taken for granted is their suspension system, which plays a crucial role in providing stability, handling, and comfort while ensuring the vehicle’s longevity. While modern suspension technologies like air suspension systems and coil springs are available, conventional leaf springs continue to dominate the suspension systems in heavy-duty trucks and trailers.
