  • Hydro-pneumatic suspensions for automotive vehicles
    Patent number: 4326733
    Abstract: A hydro-pneumatic suspension for automotive vehicles has two hydro-pneumatic shock absorbers per wheel. The shock absorbers are installed on a chassis of two C-shaped sections facing each other. A carrier fixed to the vehicle axle is pivotally coupled to the shock absorbers by rocker arms and swings. A protective rubber stop is fixed to the carrier. A reserve oil tank is coupled to the chassis between the shock absorbers and includes an oil level valve. The hydro-pneumatic suspension absorbs shock and increases the stability of the vehicle.
