Coil Spring And Leaf Spring

Coil Spring And Leaf Spring

Leaf Sprig 

• A leaf spring is a simple type of suspension spring commonly used in heavy duty vehicles.
• It is originally called as a laminated or carriage spring, and sometimes referred to as a semi-elliptical spring or cart spring.
• The center of the arc provides the location for the axle, while the tie holes are provided at either end for attaching to the vehicle body.
• It can be attached directly to the frame at the both ends or attached directly to one end,usually at the front,with the other end attached through a shackle,a short swinging arm.
• The shackle takes up the tendency of the leaf spring to elongate when it gets compressed and by which the spring becomes softer.

Coil Spring:

• A coil spring (also called helical spring) is a kind of torsion spring which can store energy and release it later when needed. It can also absorb shock and maintain the force between two contacting surfaces.
• A coil over is essential in your vehicle's suspension because it gives you optimal damping, good handling and braking, and a comfortable ride all at the same time.

Benefits of Leaf Spring:

• The ends of the spring be guided along a definite path as it deflects to act as a structural member in addition to energy absorbing device.
• Leaf spring suspensions are much more easier, since the axle is suspended by the spring, and does not require the muddled suspension geometry of the loop spring set-up. 
• Leaf springs are additionally much sturdier, and are fit for taking care of much higher burdens with less deflection than coils. 

Benefits of Coil Spring:

• Curl spring suspensions offer more scope of suspension movement, and permit the client a more extensive tuning envelope through the suspension range than leaf springs.
• Coil spring suspensions likewise usually perform better, having preferable designed geometry over leafs.

Types of Leaf Spring:

• Double eye
• Slipper-open end eye
• Slipper-hook end
• Slipper-flat end
• Slipper-radius end

Construction of Leaf Spring:

• It is built up of number of plates (known as leaf), which are reducing in length.
• The longest leaf is called as main leaf & other leaves are called as graduated leaves.
• The spring is clamped to the axle by means of U-bolts.
• Rebound clips are used to hold the leaves together.
• Central lamp is used to fix the position of leaf spring to the wheel axle.

Conclusion:

For heavy, industrial or budget-restricted applications, leaf springs will usually do an acceptable job and with regards to prove themselves a durable choice. In any case, there are very few applications which will benefit from leafs over coils where performance is concerned.
