Suspension systems in vehicles are very versatile, providing driving comfort and stability of the vehicle.
are important components. As the tire advances, the suspension system is a dynamic stabilizer that constantly balances and adjusts to changing road conditions.

Components of the suspension system; It performs basic functions such as reducing the impact of the vehicle, maintaining the vehicle ride height, supporting the vehicle weight, carrying the driving torque.

Leaf springs are mainly used in rear suspension systems to absorb and release energy associated with road movements. Leaf springs are generally used in rear suspension applications of light and heavy commercial vehicles, construction machines, trailers, buses and railway transportation.

The leaf spring commonly used in vehicles is a leaf spring with a semi-ellipse constant. The leaves are usually given a core flatness and initial curvature so that the leaf spring plies tend to flatten under load. The leaves are held together in the center by a band that wraps around them, or by a bolt-nut fastener running through the centre.

A coil spring is a mechanical device typically used to store energy and then either release it or provide a force between contacting surfaces. It is made of an elastic material that is formed into a spiral that returns to its natural length when unloaded.
