摘要： An improved rear axle suspension system wherein independently suspended wheels are supported from an extremity of a trailing wheel arm by a wheel spindle thereof, the wheel arms having extensions aligned transversely of the vehicle and constituting semi-axles, the adjacent ends of which engage in rotatable fashion with one being disposed at least partially inside the other, while the other ends are rotatably supported by bracing elements fastened to longitudinal frame members of the vehicle, the shock absorbers being attached at their upper ends to extensions of these lateral bracing elements and at their lower ends to the shanks of the wheel spindles, such that the axes of rotation of the wheel arms and of the shock absorbers are as far apart as possible, the extensions of the lateral bracing elements to which the upper ends of the shock absorbers are attached being disposed so that the shock absorbers are slightly inclined to the horizontal, whereby a sensibly variable reduction ratio between the displacement of the shock absorber pistons and the vertical excursions of the wheels is provided.

摘要： The invention relates to an air and oil suspension device notably for motor vehicles adapted to act both as a shock absorber and as a pneumatic spring. It comprises means for compensating the expansion of the fluids contained therein in case of temperature increment. In a cylinder divided into two chambers one containing a gas and the other a hydraulic fluid is slidably mounted another hollow cylinder closed at both ends and containing essentially a hydraulic fluid and a reduced volume of gas under pressure. This second cylinder has an integral external piston-forming flange provided with opposite non-return valves permitting the passage in either direction of the hydraulic fluid which is thus caused to undergo a substantial loss of pressure, and at least one opening through the wall of said second cylinder under said flange so that the pressures can balance each other on either side of the wall of said second cylinder.
