Heavy duty truck leaf springs are parts used in trucks and other vehicles used to carry heavy loads. The leaf springs are an integral part of the suspension system and thus offer support. This becomes extremely useful since they ensure a smooth ride and also prevent the truck from breaking down. To ensure effective support, one of the types of leaf springs used is the multi leaf spring.
What is a multi-leaf spring?
A multi leaf spring is a system that makes use of a series of plates that are flat and semi-elliptical in shape. These multi leaf springs are part of heavy duty truck leaf springs used in some types of trucks. The flat plates used in this system are referred to as leaves because of their shape. Since more than one plate is used, it is referred to as multi leaf.
The features of multi leaf springs include:
Within the leaves, the one at the top would be of maximum length. It is also referred to as the master leaf. It is bent at both ends. This forms the spring eyes, which are used to fix it to the truck body using bolts.
The length of the leaves gradually decreases so that the leaf at the ...
... bottom would be the shortest.
All the leaves within the multi-leaf system are held together through a center clip and through U-bolts.
There are rebound clips used to ensure that all the leaves are in proper alignment. These clips are important since they ensure the leaves don’t shift when the truck is in motion.
The multi-leaf spring system is a carefully and precisely engineered system of leaf springs that ensure the truck or heavy duty vehicles get the best support and stability to manage load and stress.
