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 exploring in detail this essential product from our extensive catalogue, the suspension spring.

What is A Suspension Spring?

Internationally, spring manufacturers refer to this spring type as either a suspension spring or a coil spring. Regardless of the name used, both serve the same purpose.

You can find suspension springs in virtually every road vehicle, including cars, motorcycles, and various forms of industrial or agricultural machinery.

Suspension springs play a crucial role in the automotive sector since they are integral components of vehicle suspension systems. Their primary function is to absorb shock from the road, thus providing a smoother ride experience.

How is A Suspension Spring Designed and Manufactured?

Throughout our years of experience in manufacturing and supplying suspension springs globally, we have adapted our products to meet the diverse requirements of various projects, ranging from unique niche applications to large-scale multinational product lines.

During the manufacturing process, we utilize a wide array of materials, including:

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

Diverse steel alloys are the most commonly used materials for suspension coil springs and valve springs, as they possess the necessary strength, hardness, and resistance to sag and temper, making them suitable for your suspension coil spring.

Once the spring’s design is tailored to the required specifications and appropriate material is chosen, the manufacturing of the final product begins. The specifics of how a suspension spring is made may not vary significantly despite differences in specifications.

What Makes Suspension Springs So Popular?

Suspension springs, when combined with shock absorbers, not only provide a more comfortable ride for the driver but also ensure that the wheels maintain continuous contact with the road, enhancing control.

Improved grip is essential for better handling and overall road safety. Conditions such as icy roads exemplify how a vehicle's handling can suffer without adequate grip. Sturdy suspension springs help prevent such dangerous driving scenarios, ensuring safety in all but the most severe weather conditions.

Shock absorbers work alongside suspension springs to create a smooth experience while driving. Springs absorb the minor imperfections of a typical road, preventing the driver from feeling them, while the shock absorbers ensure that tires remain firmly on the road.

Different Types of Suspension Spring

There is a wide range of suspension spring types, suitable for the various vehicles on the road. As seasoned manufacturers, we have produced suspension springs tailored to many vehicle designs.

We are acutely aware of the necessity for each suspension spring to align with the precise specifications of the vehicle it will be fitted into. For instance, motorcycles, touring vehicles, and performance race cars demand the strongest springs due to their performance profiles, while a standard domestic vehicle may require a more cost-efficient suspension spring design.

Progressive Vs. Linear Suspension Spring

The manufacturing method significantly impacts the performance of a vehicle. As such, understanding your requirements for the final product is crucial. There are two fundamental types of spring rates to evaluate: linear and progressive.

The spring rate defines the stiffness of the spring, which is the primary distinction between a linear design and a progressive one.

Linear rate suspension springs are known for their simplicity, possessing a single variable that offers a consistent and predictable rate. This predictability allows for accurate calculations of how the spring will function under varying road conditions. Their design ensures that handling is stiff and responsive, making them suitable for standard cars or trucks.

Conversely, while linear rate springs are prevalent, they are only efficient in situations they are designed for. In contrast, progressive rates offer greater adaptability. Although they are more complex to predict, progressive springs can accommodate both comfort and performance within a single design—an attractive option for new car designs.
