Teräsjousitus

Teräsjousitus, literally translated as "steel suspension" from Finnish, refers to a type of vehicle suspension system that primarily utilizes steel springs. This is a broad category encompassing various designs, but the core component is typically a coil spring, leaf spring, or torsion bar made of steel. These components are crucial for absorbing shocks from the road surface, maintaining tire contact with the ground, and providing a more comfortable ride for occupants.

Steel springs are chosen for their durability, strength, and cost-effectiveness. They work by deforming under load and then returning to their original shape, dissipating the energy from impacts. Coil springs, the most common type in modern passenger vehicles, are wound metal rods that compress and expand. Leaf springs, often found in trucks and older vehicles, consist of several layers of steel strips that bend. Torsion bars are steel rods that twist when subjected to rotational force.

While effective, traditional steel suspension systems can sometimes be less sophisticated than advanced adaptive or air suspension systems, which offer adjustable stiffness and ride height. However, steel suspension remains a workhorse in the automotive industry due to its reliability and manufacturing simplicity. Its widespread use across a vast range of vehicles, from small cars to heavy-duty trucks, highlights its enduring practicality and essential role in vehicle dynamics and driver comfort.
