1.38 Knowing the parts of a vehicle: Polyurethane spring suspension system

The suspension system is an essential part of any vehicle. He is responsible for absorbing road impacts and irregularities, providing smooth and comfortable driving. One of the types of suspension systems that has gained popularity in recent years is the polyurethane spring suspension system.

What are polyurethane springs?

Polyurethane springs are a type of suspension spring made from polyurethane, a synthetic material known for its durability and strength. Unlike traditional steel springs, polyurethane springs will not rust or corrode, making them an attractive option for vehicles that are frequently exposed to adverse road or weather conditions.

How does the polyurethane spring suspension system work?

The polyurethane spring suspension system works similarly to other suspension systems. Polyurethane springs are compressed and released as the vehicle goes over bumps in the road, absorbing impact and providing a smooth ride.

One of the main differences between polyurethane springs and traditional steel springs is the way they respond to compression. Steel springs tend to have a linear compression ratio, meaning they compress at a constant rate. Polyurethane springs, on the other hand, have a progressive compression ratio. This means that they compress at a rate that increases as the spring is compressed. This can provide a smoother ride on rough roads and better vehicle control when driving at high speeds.

Advantages of polyurethane springs

There are several advantages to using polyurethane springs in a suspension system. First, they are extremely durable. Polyurethane is a tough material that can withstand a great deal of wear and tear without deteriorating. This means polyurethane springs can last longer than traditional steel springs, which can save you money on long-term replacements.

Second, polyurethane springs can improve vehicle performance. Due to their progressive compression ratio, they can provide a smoother ride on rough roads and better vehicle control at high speeds. They can also improve vehicle stability, making it less prone to rollovers and other types of instability.

Considerations when choosing polyurethane springs

While polyurethane springs have many advantages, there are also some considerations to take into account when choosing this type of suspension system. First, they tend to be more expensive than traditional steel springs. While they can save you money in the long run due to their durability, the initial cost can be higher.

Second, although polyurethane springs may provide a smoother ride on rough roads, they may not be as comfortable on smooth roads as steel springs. This is because the polyurethane springs' progressive compression ratio can make the ride a little stiffer on smooth roads.

In conclusion, the polyurethane spring suspension system is an attractive option for many vehicles due to its durability, performance and corrosion resistance. However, it's important to consider your needs and the type of driving you do before deciding whether this system is right for you.
