lehtvedru

Lehtvedru is a type of spring commonly used in vehicles, particularly for suspension systems. It is constructed from one or more flat, elongated strips of metal, typically steel, that are layered and curved. These strips are known as leaves, and hence the name "leaf spring." When a load is applied, the leaves bend and slide against each other, absorbing and distributing the energy. This flexing action provides a springy effect, cushioning the ride and supporting the weight of the vehicle.

The simplest form of a leaf spring is a single, slightly curved piece of metal. More complex designs, often called multi-leaf springs, consist of several layers of leaves of varying lengths. The longer leaves are placed at the top and bottom, providing primary support, while shorter leaves are nested in between to help distribute the load more evenly and prevent excessive flexing. One end of the leaf spring is usually fixed to the vehicle's chassis, while the other end is attached via a shackle or a more rigid mount. This design allows for controlled movement and is known for its durability and robustness. Leaf springs have been a staple in automotive suspension for over a century, valued for their simplicity and effectiveness, especially in heavy-duty applications like trucks and trailers.
