Leaf Springs

A leaf spring is made up of thin, arc-shaped plates that are mostly used in vehicles to connect an axle and chassis, allowing for vertical flexing over uneven roads. The most common type is a lateral leaf spring that runs lengthwise and is mounted perpendicular to the axle.

Manufacturing & Materials

Manufacturing Process

Leaf springs are manufactured by pressing layers of tempered steel together that are then curved into an arc and fastened together. This reinforced shape absorbs shock and distributes loads to provide stability.

Materials

Steel is used for manufacturing leaf springs as it can endure high levels of stress and strain. It is typically a high-carbon steel or alloy steel that has been heat-treated to enhance its hardness.

Common Uses of Leaf Springs

Transport: Heavy-duty trucks, lorries and vans rely on leaf springs when delivering or transporting goods. Leaf springs manage any heavy loads that affect the suspension that could cause the vehicle to be lower to the ground by absorbing the shock of any pothole or speedbump.
Military: Emergency response vehicles, military transport and trailers also depend on leaf springs for their robust performance in demanding scenarios which can include off-road.
Railway: Passenger carriages and freight wagons utilise leaf springs to ensure a smooth ride over long distances, effectively managing vibrations and enhancing passenger comfort.

Small Leaf Springs

We also manufacture small leaf spring assemblies designed for applications with limited space that still require suspension and load-bearing capabilities. These compact springs are frequently used in lightweight vehicles and precision machinery, such as conveyor systems and packaging equipment, where they effectively absorb vibrations and maintain consistent pressure.

Small leaf springs are commonly used in consumer products, such as office chairs and exercise equipment, as they offer controlled resistance while maintaining sleek designs. Their versatility also applies to the aerospace and defence industries, where they play a vital role in components like aircraft landing gear.
