Steel

We produce all types of leaf springs for light, medium and heavy trucks.

Mono leaf

High-tech spring with one single leaf. The level of tension obtained enables maximum use of the steel used and the consequent weight reduction.

The design of this leaf spring requires steels of very high quality and strict control of the manufacturing process; they cannot be manufactured at every facility.

Parabolic Springs

The rolling section of these leaf springs has a parabolic function.

The distribution achieves constant tension across the entire leaf of the spring under any stress level. This ensures better use of the material compared to semi-elliptical or "traditional" leaf springs. They can be manufactured with one or two rigidities, depending on the design.

Pneumatic Springs

This type of spring is used in the pneumatic suspension systems from which they take their name.

While the steel leaf springs referred to above are capable of assuming part of the axle-guiding, a pneumatic cylinder can only absorb vertical loads. Pneumatic springs provide the benefits of a pneumatic suspension system without losing the axle-guiding. Therefore, these leaf springs have the dual function of maintaining the axle-guiding and providing support for the pneumatic cushion.

Pendelfeder

Unlike the others, this type of leaf spring controls two of the vehicle's axles.

Unlike the others, the spring is attached to the truck at the centre and the axles are connected at both ends. They are used in construction or heavy-duty vehicles. They can be manufactured with one or two rigidities, depending on the design.

Multileaf

These springs usually consist of a high number of leaves with a constant cross-section.

In technical terms, they are simpler to manufacture. Their robustness and the fact that they can be repaired easily mean they are still used in a large number of applications. As in the previous cases, they can be designed with one or more rigidities.

Composite

Our lightweight structural products are designed for both light and heavy vehicles.

The products manufactured in glass fiber reinforced polymer (GFRP) by MBHA Composites have the following benefits:

- Lighter designs, reducing weight by 30 to 68% compared to their steel counterpart.

- Excellent mechanical properties, especially their high resistance to fatigue.

- High resistance to corrosion and environmental agents.

Mono leaf

This spring comprises one single leaf of composite material. The parabolic section optimises the use of the material in relation to the corresponding forces. This type of spring is designed to control the front axle of the vehicle.

Total weight reduction

67,8%

Hybrid

This spring comprises a master leaf of steel and one or more leaves made of composite material. Each sheet is formed by a parabolic section for maximum use of the material in accordance with the corresponding forces. This type of configuration is designed to work on both front and rear axles and can be used in on-road and works (off-road) situations.

Anti-roll bar

Elastic component with both ends joined to moving parts that require a partially synchronised movement and the body attached to the chassis. This configuration makes it able to transfer part of the compression force of the suspension associated with the external wheel towards the internal wheel, thus helping to reduce the inclination of the vehicle body.
