An Introduction to Suspension Springs

The demands on spring manufacturers are at their highest when manufacturing suspension springs for vehicles. The automotive industry relies heavily on the highest-quality suspension springs for their vehicles.

As a prominent member of The Institute of Spring Technology and leaders in suspension spring manufacturing for decades, we understand the exacting standards required when manufacturing premium suspension springs.

In this article, we will be looking into more detail about this essential product from our extensive catalogue, the suspension spring.

What is A Suspension Spring?

Internationally, spring manufacturers have two names for this spring type, suspension spring and coil spring, but despite the different names, they both have the same applications.

You will find suspension springs in every road vehicle, from cars to motorbikes and even more industrial or agricultural machinery.

Suspension springs are an essential part of the automotive sector due to their application in vehicle suspension systems. They essentially take all the bumps out of the road and give you a much smoother ride.

 

 

How is A Suspension Spring Designed and Manufactured?

During our time manufacturing and supplying suspension springs around the globe, we have had to adapt our product to suit the needs of every project, from small niche applications to huge multinational product lines.

When we manufacture our suspension springs, we work with a wide range of:

• Copper
• Steel
• Titanium
• Superalloys such as Hastelloy, Nimonic and Inconel

The springs&#; high strength requirements for vehicle suspension make steel alloys the most used for suspension coil springs and valve springs. The steel alloy has the required strength and hardness and offers a higher sag and temper resistance, making it an excellent choice for your suspension coil spring.

Once the spring has been designed to suit the required specifications and chosen material, it&#;s time to manufacture the final product.

The specifics of manufacturing a suspension spring will vary very little despite the difference in the specification.

What Makes Suspension Springs So Popular?

When suspension springs are combined with shock absorbers, not only does it provide a smoother ride for the driver, but they also make sure that the wheels are in contact with the road at all times, which increases control.

The increased grip is integral to better road handling and general road safety. Icy roads show how a car&#;s handling becomes impossible without adequate grip on the road. Strong suspension springs prevent this dangerous driving from occurring in all but the harshest weather conditions.

Shock absorbers and suspensions springs work together to create a smooth ride. The springs will absorb and release the many minor imperfections in the average road, so you don&#;t feel it, and the shock absorbers help keep your tires gripped to the road.

Different Types of Suspension Spring

There are as many suspension spring types as vehicles on the road. As experienced suspension spring manufacturers, European Springs has manufactured suspension springs for every vehicle design.

We understand that each suspension spring needs to be tailored to the exacting specifications of the vehicle it will be installed into. For example, motorcycling, touring, and indy cars all put high demands on their suspension, so they require the most durable springs. Alternatively, a domestic vehicle won&#;t be operating under such extremes, so they can afford to choose a more cost-effective suspension spring design.

Progressive Vs. Linear Suspension Spring

The way the spring is manufactured will significantly affect the vehicle&#;s performance; that&#;s why it&#;s important to know what you want in your final product. There are two initial aspects of a suspension spring to consider: linear or progressive rates.

The spring rates will tell you how stiff a spring is and it&#;s the most significant difference between a linear or progressive design.

The benefits of a linear rate suspension spring are their simplicity. A linear rate has only one variable to it and has a consistent, predictable rate. This predictability makes accurately calculating how the spring will act under various road conditions very easy. Since this spring has only one way to respond when in use, the handling feels stiff and responsive and is an excellent choice for an average car or lorry.

However, whilst the linear rate is more popular, it can only handle the situations it was designed for, and you will have to choose to design your spring more toward either handling or comfort but not both; this is where progressive rates come in.

The benefits of progressive rate suspension springs are their adaptability. Progressive rates are more complicated to predict than linear, but they have the potential to handle both comfort and handling in a single suspension spring, something worth exploring in any new car design.

Suspension springs are the link between wheels and car body. Their primary task is to compensate uneven road surfaces and thus provide an assurance of high levels of ride comfort. Secondly, they must ensure that the wheels always have safe contact with the road regardless of its condition. Reliable transmission of drive, braking and transverse forces relies on these requirements being met. As such, suspension springs are one of the most safety-critical components of modern vehicles. They affect handling, roadholding and braking performance.

From the point of view of design, there are suspension springs with linear and progressive spring rate. With linear springs, the spring force increases in proportion with the extent to which they are squeezed together. Progressive springs start with a soft characteristic curve and become harder the further they travel.

Types of suspension springs

The following types of spring are primarily used in today's cars:

Cylindrical suspension springs

These are conventional cylindrical suspension springs with a linear spring rate.

Inconstant wire suspension springs

With this type of spring, the diameter of the wire used decreases towards the end of the suspension spring. Assuming normal road conditions and normal load, the soft ends of the spring can be relied upon for very comfortable ride properties. As well as improving ride comfort, this relieves the load on the

Mini-block springs

Mini-block springs are barrel-shaped. They are manufactured from tapered wire. This means that they generate a progressive spring rate. The design of the ends of the springs avoids direct contact from winding to winding. The main feature of the mini-block springs, which were developed from inconstant wire during the , is that when under load, the windings of the ends intertwine without touching. When the ends of the mini-block springs are squeezed together and lie flat on the spring cups (which usually consist of a rubber block), the number of active windings drops and the spring rate increases.

Banana-shaped side load springs

This type of spring controls force distribution for the entire wheel suspension, reducing the friction between the shock absorber piston rod and its gasket. This helps to improve
