Horstman Hydrogas®

Developed by Horstman in the 1980s for a range of vehicles, Hydrogas® was designed from the outset to replace torsion bars and provided a revolutionary increase in cross-country mobility.

This allowed the vehicle designer to overcome the internal packaging constraints, vulnerability to mine blast and crew exposure to the fragmentation that all result from torsion bars.

The hydro-pneumatic suspension uses high-pressure nitrogen gas and an integral oil damper. Robust environmental seals make the Hydrogas® a sealed module suitable for robust environments.
