Piedrafita revolutionises tactical mobility with its new linear suspension for military vehicles
Piedrafita, a leading company in engineering solutions for defence, announces the launch of its innovative linear hydropneumatic suspension, a disruptive advance in suspension systems for armoured vehicles.
This new system, designed and produced entirely by Piedrafita, integrates the elastic and damping elements into a single unit, offering optimised performance, lower weight and a more compact design, all with greater ease of integration.
The new linear suspension represents a qualitative leap forward compared to conventional configurations, offering key advantages in terms of efficiency, reliability and cost. Its integrated design drastically reduces the number of components, simplifying production and maintenance processes, reducing weight (approximately 20 kg per wheel station) and contributing significantly to the overall mobility of the vehicle.
Compact, lightweight and powerful
One of the main advantages of this suspension is its small size. Unlike traditional systems that require additional space to house the suspension elements separately, Piedrafita's proposal allows for tighter integration in limited spaces. This makes it an ideal solution for state-of-the-art armoured vehicles and for modernisation programmes for existing platforms.
Greater comfort and mobility, even in extreme conditions
The built-in hydraulic preload system significantly improves the vehicle's dynamic performance, providing a smoother, more stable and safer ride on challenging terrain. Unlike conventional solutions, which are sensitive to temperature variations, Piedrafita's technology maintains the vehicle's mobility properties even in extreme temperatures or under intensive use. Another added value derived from this technology is the ability to generate non-linear elastic curves that are optimised to the maximum for each vehicle and axle.
Triple valve technology: guaranteed control and durability
One of the most innovative features of Piedrafita's linear suspension is its patented Triple Valving technology, which ensures precise control across the entire operating range, regardless of environmental conditions. This technology protects the system from sudden pressure increases, prevents degradation of characteristics at high temperatures and eliminates the need for periodic maintenance, significantly reducing operating costs.
In addition, the system incorporates hydraulic compression and extension stops, integrated internally to smooth the transition at the ends of the travel, protecting both the vehicle and the crew.
Ready for the digital era
The suspension is designed to be fully compatible with HUMS (Health and Usage Monitoring System) systems, allowing plug & play integration with digital data acquisition, control and suspension diagnostic systems. This capability makes Piedrafita's hydropneumatic strut an ideal choice for modern, connected platforms.
Versatile applications for all types of platforms
With a load capacity of between 0.5 and 2.5 tonnes per wheel, this solution is ideal for both new-generation military vehicles and armoured platform upgrade programmes. Piedrafita's linear suspension sets a new standard in tactical mobility and reliability in demanding operations.
