bladfjädring

Bladfjädring, also known as leaf spring suspension, is a traditional type of vehicle suspension system that utilizes layered strips of metal, called leaves, to absorb shocks and support the vehicle's weight. This suspension method has been historically common in trucks, heavy-duty vehicles, and some passenger cars due to its durability and simplicity.

The leaf spring assembly typically consists of several flat, elongated steel strips that are stacked and curved to provide resilience. The central part of the leaf spring attaches to the vehicle's frame via a shackle or a fixed mounting point, while the ends connect to the axle using U-bolts or similar fasteners. When the vehicle encounters bumps or uneven surfaces, the leaf springs flex and distribute the load evenly, providing a smooth ride and maintaining tire contact with the road.

Advantages of bladfjädring include its robustness, ease of manufacture and maintenance, and cost-effectiveness. Its straightforward design facilitates easy repairs and replacements, making it a preferred choice for commercial and heavy-duty applications. However, compared to modern suspension systems, leaf springs tend to offer less ride comfort and handling precision, and they can cause increased vehicle weight and reduced ride quality.

While less common in modern passenger vehicles, leaf springs remain prevalent in certain markets and vehicle types, particularly where durability and load-bearing capacity are prioritized over ride comfort. Advances in suspension technology have led to the adoption of coil spring and air suspension systems, but bladfjädring continues to be a reliable solution in specific contexts.
