Leaf Springs Vs Coil Springs: Which is better?

A suspension system is a system of springs, shock absorbers and linkages. They connect a vehicle to its wheels and allow relative motion between them both. They are responsible for a vehicle&#;s handling and braking for safety. There are a variety of independent suspension systems, though we are going to focus on the comparison of the two main suspension systems.

Leaf springs

Leaf spring suspensions are simpler when it comes to the functionality as the axle is suspended by the spring and doesn&#;t require arduous suspension geometry of the coil-spring set-up. Leaf springs are much sturdier in comparison to coil springs. They&#;re capable of handling much highest loads with less deflection than coils, trucks with leaf springs are also easier to raise or lower.

Leaf springs&#; simply means each spring is attached at fixed points on the chassis, it leaves a miniscule area for adjustability and customisation of the suspension geometry. These springs also flex a great deal less than coil springs which means loss of wheel-to-ground contact under extreme conditions.

Advantages

• Strong and simple construction, linking holds the axle in position without the need for separate linkage.
• Leaf springs can support the weight of the chassis of a vehicle and so it is perfect for use on commercial vehicles.
• They control axle damping- to damper means the main function of a shock. They are used to control spring oscillation by using hydraulic fluid.
• Typically, they are simple in design and cheaper to produce

Disadvantages

• They aren&#;t always the easiest to install
• Over time the springs tend to lose shape and can be prone to sagging. When the spring starts to become uneven, it can alter the cross weight of the vehicle and therefore may affect the handling. This can also alter the axle-to-mount angle.
• Wind-up and vibration can be caused by acceleration and braking torque. The wind-up can also cause nose-diving and rear-end squat.

Coil springs

Coil spring suspensions provide more range of suspension movement and allow the user a wider turning envelop through the suspension range than the leaf springs. Practically all high-performance applications use coil springs where possible if the budget permits.

Two main drawbacks to a coil spring suspension are the cost and load-bearing, cost isn&#;t much of an issue if the vehicle is equipped with coil springs, retro-fits are quite expensive and time consuming. Coils are not ordinarily preferred for heavy vehicles as the coil on axle setup isn&#;t remotely as stable or strong as proper leaf springs.

Each of these suspension systems have their applications unique to their functionality and are used accordingly. Leaf springs usually do an acceptable job and prove themselves a durable choice in the case of heavy, industrial or budget-limited applications. There are a very few applications which benefit from choosing a leaf spring over a coil spring when it comes to performance.

Advantages

• Good for vehicles that are on rough terrain often
• Improve ride quality from reducing the bounce
• Gives vehicle its height and keeps it off the ground
• Lightweight
• Low cost &#; made from steel and other inexpensive metals
• They don&#;t need any maintenance &#; you don&#;t have to lubricate the coil or take any great care in it for it to work.

Disadvantages

• Not as suited for heavy vehicles as the leaf springs are, due to the concentration on the vehicle weight
• More subject to cracking and breaking under excessive amounts of pressure, especially when it has slightly corroded
• You may need to get other enhancements to ensure that the coil lasts longer

FAQs

A coil spring absorbs the vibrations and bumps from the road, this makes driving much smoother. The coil spring is a key component of a vehicle&#;s suspension system and is designed to absorb shock. The key role of a coil spring is to remove or reduce the vibrations and bumps from the drive, giving you a more comfortable journey.

A leaf spring is a long bundle of spring material that flexes when put under pressure from a vehicle&#;s axle when it moves. The leaves compress and absorb the motion, which transfers the energy to the chassis. 

A coil spring can break for many reasons. Although it isn&#;t often, coil springs can break over time due to wear and tear. One of the most common reasons coil springs break is because of Winter. Ice, snow, and cold temperatures are all huge factors, as well as the salt on the roads as this accelerates the corrosion. Other things such as sudden impact from driving over speed bumps or pot holes can also cause damage or break the coil spring.

We would say no, no way. If your leaf spring has got to the point where it appears to require welding, we would strongly recommend replacing it. You shouldn&#;t weld near a spring, so welding the spring itself is an absolute no from us.

The purpose of a coil spring is to absorb the vibrations and bumps in the road whilst driving. This gives you a much smoother driving experience and is more comfortable for you and any passengers.

4 Advantages of Coil Springs

A coil spring manufacturer makes many kinds of springs, all with their own advantages and disadvantages. The grouping of coil springs as a whole offers a large range of benefits that make them ideal for use in many industries, from to production to furniture making. If you have the choice between a coil spring and another kind of spring, consider the following advantages of coil springs before making your final decision:
Coil springs are lightweight: Coil springs are surprisingly light for the power they provide. The coiled steel makes the spring stronger than the metal would be if it retained the original straight shape. The heating and coiling process also helps strengthen the metal, making it possible to use less metal to hold larger weights.
Coil springs are inexpensive: Most springs are made from steel and other low-cost metals. These metals are easy to find anywhere, and the cost of the metal is low. Such a small amount of metal goes into each spring, that coil springs are one of the most economical choices for any type of use.
Coil springs are maintenance-free: A coil spring requires no maintenance. You don&#;t have to lubricate the spring, or clean it, or give it special coatings or care for it to work. The only problem that may occur with springs is that they may break on occasion. However, if a coil spring breaks it is an easy matter to fix it.
Coil springs are versatile: There are hundreds of varieties of coil springs that a coil spring manufacturer can create for a variety of different uses. Depending on what you want to use the spring for, you can choose tension springs, compression springs, or torsion springs. Each coil spring provides a unique service to the tool and helps make the job of the tool or machine much easier.
