Horstman Hydrostrut®

The hydro-pneumatic suspension uses high-pressure nitrogen gas and an integral oil damper and provides for an easy path to ride height and wheel station load adjustment . Compact and providing excellent ride this is a superior selection for 4x4, 6x6 and 8x8 vehicles compared to coil or leaf spring, conventional shocks or air bag technology.

Developed by Horstman in the late 1980s for tracked vehicle and wheeled applications, Hydrostrut® was designed from the outset to eliminate the need for a separate spring by combining the gas spring into the damping unit. This allows the vehicle designer to overcome internal packaging constraints in the case of torsion bars or external packaging constraints in the case of coil springs.

The hydropneumatic suspension uses high-pressure nitrogen gas and an integral oil damper. Robust environmental seals make the Hydrostrut® a sealed module suitable for robust environments. The rising spring rate of compressed gas provides a natural progressive end stop to travel and reduce shock loads into the chassis and crew. Separate bump stops can be eliminated or significantly reduced in size and cost.
