Why Do We Use Leaf Springs for Heavier Vehicles?

A leaf spring, or a carriage spring, is a simple type of spring usually utilized for wheeled vehicles. Also, it is one of the oldest sorts of springing in medieval times. One the advantages of a leaf spring over a regular spring, which is helical, is that the leaf spring’s end might be directed along a specific path. Leaf springs for heavier vehicles can be fixed to the frame, or it can be fixed at one end directly, with the frontage normally fixed through a bind, which is a small swinging arm. The bind takes up the inclination of the leaf spring to lengthen if compressed. This causes the supple springiness.
