Study on damping characteristics of hydropneumatic suspension …

WebThe suspension is mainly composed of an upper pneumatic chamber and a lower hydraulic chamber. The hydropneumatic cylinder-piston assemblies connect the load wheels to the tracked frame. The lower end (piston) is mounted on the U-shaped shaft with a load wheel. The upper end (cylinder) is fixed with the tracked frame. WebAn in-arm suspension unit was developed for retrofit onto a Marine Corps Assault Amphibian Vehicle.
