Leaf Spring
Characteristics
- The leaf spring is a flexible element used to absorb & store energy and then to release it.
- During this cycle, the stress in the spring must not exceed a certain maximum in order toavoid settling or premature failure.
- This consideration limits the amount of energy which can be stored in the spring.
- The disadvantage of leaf spring is heavier in mass than other type of springs like coil springs.
- But the advantage of leaf spring is can be used as attaching linkage or structural member of suspension system.
Process Flow
The components of suspension system (Light truck near suspension will consist of):
Rear Axle
Multi Leaf Spring
U-Bolts
Shackle
Bushing
Frame Bracket
Spring Pin
Eye Bolt
The front eye of spring and one end of the shackle are mounted to the frame bracket through bushing and pins.
The rear eye of springs is connected to the other end of shackle through bushings and eye bolt.
The characteristics of leaf springs are affected primarily by the spring rate, the change of load per unit of deflection and the deflection of the spring.
