Steel Leaf Springs
We design and produce all types of leaf springs for light, medium and heavy trucks.
Monoleaf
A technologically advanced single-blade leaf spring. The achieved stresses enable maximum utilization of the steel, resulting in weight savings. The design of this leaf spring requires the use of extremely high-quality steels and a high level of process control, as they cannot be manufactured in just about any facility.
Parabolic Leaf Springs
The rolling profile of these leaf springs follows a parabolic function. With this distribution, a constant stress level is achieved over the entire leaf spring branch under all stress levels. This results in better material utilisation compared to semi-elliptic or "traditional" leaf springs. They can be manufactured with one or two stiffnesses, depending on the design.
Pneumatic Leaf Springs
This type of spring is used in the air suspension from which it takes its name. While the steel springs above are able to take over part of the axle guidance, an air cylinder can only absorb vertical loads. By using air springs, it is possible to utilise the advantages of an air suspension without losing the aforementioned guidance. These springs therefore have the dual function of retaining the guidance and supporting the air cushion.
Pendelfeder
This type of leaf spring, unlike the others, controls two axles of the vehicle. Unlike other leaf springs, the leaf spring is attached to the truck at the centre and the axles are joined at both ends of the leaf spring. They are used on construction or heavy-duty vehicles. They can be manufactured with one or two stiffnesses, depending on the design.
Multileaf
Leaf springs that usually consist of a large number of blades with a constant cross-section. Technically simpler to manufacture. Their robustness and ease of repair mean that they are still used in many applications. As in previous cases, it is possible to design them with one or more stiffnesses.
Monolam Front Leaf Spring
Leaf spring consisting of a single leaf made of composite material. The parabolic profile optimises the use of the material in relation to the forces. The eyelets are also made of composite material. This type of leaf spring is designed to control the front axle of the vehicle.
Overall weight reduction
Hybrid Front Leaf Spring
Front leaf spring consisting of a main steel leaf and a second leaf made of GFRP. The parabolic profile optimises the use of the material in relation to the stresses. This type of leaf spring is designed to control the front axle of the vehicle.
Overall weight reduction
Full Composite Tandem Leaf Spring
Tandem type rear leaf spring made entirely of GFRP. In this case, the leaf spring also consists of a main spring and a leaf spring. In this way, two stiffness ranges can be offered for greater comfort depending on the truck load.
Overall weight reduction
Hybrid Trailer
Trailer leaf spring consisting of a main steel leaf and a second leaf made of GFRP. The parabolic profile optimises the use of the material in relation to the stresses, making it possible to reduce from an 11-leaf leaf spring to a 2-leaf leaf spring.
Overall weight reduction
Hybrid Tandem Leaf Spring
Tandem type rear leaf spring consisting of a steel main leaf and a GFRP second leaf.
Overall weight reduction
Monolam for Trailers
Trailer leaf spring consisting of a single GFRP leaf. The parabolic profile optimises the use of the material in relation to the stresses and can be reduced from an 11-leaf leaf spring to a single leaf spring.

360º SERVICE
The best product and service possible as a result of our commitment to excellence.
R+D+I Centres
We develop projects with advanced technological content, from product and process design to the homologation of the products with our own R&D team.
We promote research, development and innovation to obtain new technological solutions, which continuously improve our know-how. More than 50 years in the sector, as well as the know-how acquired by our engineers, allows us to propose the most optimal solutions, being pioneers in the presentation of solutions of high technological value, enabling us to manufacture all types of prototypes for our customers.
Product Design
Through its R&D Department, MBHA Projects offers its customers the opportunities to partner on the design and subsequent development of all types of leaf springs and other components.
Both the use of CAD tools and the following Finite Element analysis of the leaf spring during installation enable us to optimize its design to the fullest extent possible.
On the other hand, our relationship with raw material suppliers allows us to obtain steels that enable us to achieve higher tensions.
Process Design
A high-tech product, such as the one designed by MBHA Projects, requires a cutting-edge manufacturing procedure.
Our Engineering Department is constantly aiming to enhance the efficiency of our manufacturing operations. This enables us to obtain products that meet our clients' increasing expectations, as a consequence of our extensive experience in the sector.
Product Homologation
MBHA Projects has the necessary resources to test and certify the products it designs and manufactures, verifying that customer requirements are met.
All MBHA certificates can be found on this website, by visiting the Downloads section.
