Liquid-compression suspensions for automobile vehicles

摘要

A suspension system for automobile vehicles in which each vehicles wheel is carried by at least one suspension arm articulated on the chassis of said vehicle by means of a pivotal shaft and driving in rotation two symmetrically-disposed piston-cylinder units in such manner that a force transmitted to said wheel applies pressure on a liquid compressed between said pistons and the bottoms of said cylinders, said liquid communicating with an otherwise closed tank filled with a compressible liquid, the nature and mass of which determine the flexibility of said suspension system, and in which the wheel-suspension cylinder or cylinders of one wheel are rigidly fixed on an entirely closed fluid-tight casing, fixed with respect to said vehicle and traversed in a fluid-tight manner by the pivotal shaft of said suspension arm which drives in rotation the crank-pin or pins receiving said piston rods, said casing being filled with the same fluid as that which fills the space between said pistons and said cylinder bottoms, but at a lower pressure.
