CONVENTIONAL LEAF, LOOSE LEAF, PARABOLIC LEAF

The spring type:
+ Tweezers leaves:

Tweezers are made of a curved spring steel band, called "leaf spring", and stacked in order from shortest to longest. Episode leaf springs are pressed together by a bolt or rivet in the middle, and to
Generally, the longer the better soft tweezers. Number of leaf springs, the springs as much as hard, withstand greater loads. However, hard spring will affect the smooth.
to be disproportion leaves, they are holders in a number of positions. The two longest first leaf (the leaf springs) are bent into a ring to assemble the chassis or other structures.
+ Characteristics of tweezers:
- Spring itself has enough rigidity to keep the car in place should not need to use the other link.
- Tweezers perform self-control functions ranging through friction between the spring leaves.
- Tweezers have sufficient strength to withstand heavy loads.
- Because of the friction between the spring leaves so hard springs absorb small vibrations from the road surface. So spring is often used for large vehicles, transporting heavy loads, should be more emphasis on durability.

+ Deflection of the spring:
- The effect of deflection:
When the spring is bent, making the deflection on each palm leaf springs, and friction between the leaf springs appear to fluctuate quickly off of tweezers. This friction is called the friction between the spring leaves. It is one of the most important characteristics of tweezers. However, this also reduces friction smooth running of the car, because it makes the spring bending is reduced. So, spring is usually used for trucks.
When this rhythm up, sag springs keep the leaves together tightly, preventing soil, sand ... entered into between the leaf springs and abrasive.
- Measures to reduce friction between the spring leaves
Place the pads on the noise between the spring leaves, the leaves at the top, so they easily slide over each other. Each leaf spring ends are bevelled so they create a pressure suitable for contact with each other.
+ Side Tweezers
The truck and load up changes needed additional secondary tweezers. Tweezers tweezers mounted on the side. With small loads, only the main spring, but when the load exceeds a certain value, both primary and secondary springs are working.
