1.48. Knowing the parts of a vehicle: Wooden spring suspension system

While most modern vehicles use steel or air spring suspension systems, it is important to understand the wood spring suspension system, which was common on older vehicles and is still used on some vintage and custom vehicles . This suspension system has its own characteristics and maintenance requirements.

Understanding the Suspension System

In any vehicle, the suspension system is crucial to maintaining ride comfort and stability on the road. It absorbs road impacts and vibrations, preventing them from being transferred to the vehicle body. The suspension system also helps keep the tires in constant contact with the road, improving traction and safety.

What are Wood Springs?

Wood springs, also known as laminated wood springs, are made from several layers of wood, usually ash, that are glued together to form a spring. They are used in a beam suspension system, where the wooden spring extends between the axle and the vehicle frame. The wooden springs are flexible and can absorb a significant amount of road shock.

Advantages and Disadvantages of Wood Springs

Wood springs have several advantages. They are lightweight, which can improve the vehicle's fuel efficiency. Additionally, wood has natural vibration dampening properties, which can provide a smoother ride. However, wooden springs also have disadvantages. They may be more susceptible to moisture and pest damage, and may require more maintenance than steel or air springs.

Maintenance of Wood Springs

Regular maintenance is essential to keep wood springs in good working order. This includes regularly inspecting the springs for signs of wear or damage, such as cracks or deformation. If signs of wear are found, the springs must be replaced.

In addition, wooden springs must be protected from moisture to prevent them from rotting. This can be done by applying an oil or varnish based sealant to protect the wood. The springs must also be protected from pests, such as termites, which can damage the wood.

Conclusion

Although the wooden spring suspension system is less common in modern vehicles, it still has its place in automotive history. Understanding this system and knowing how to care for it can be helpful for those who own or maintain vintage or custom vehicles with wood springs. As always, regular maintenance and attention to detail is key to keeping any suspension system working well and keeping your vehicle on the road.
