  • Patent number: 5743553
    Abstract: An active suspension system, in particular for motor vehicles, is provided whose suspension or support units arranged between the sprung and the unsprung mass have, in each case, a passive, uncontrolled spring element and, arranged in series with the latter, a hydraulic displacer unit with controllable adjustment. The arrangement of displacement pick-ups, which reproduce the stroke position of the sprung mass relative to the unsprung mass and the stroke of the displacer unit, allows for carrying out a regulation of the current supporting forces by a required/actual value comparison which uses only the displacement measurements.

  • Patent number: 4274701
    Abstract: In the illustrated embodiment, the spring arms have an integral connecting web rearwardly from the pin contact region so as to form a U-shaped locking spring with rearwardly directed locking edges. As the spring system is assembled into a spring chamber, a tapering face progressively bends the legs of the locking spring inwardly, a locking edge springing outwardly to engage in front of a ledge as the system reaches the operating position, and the forward edge of the web restraining further forward movement. Each spring system is thus locked in operating position while being individually removable by means of a blade inserted from the forward side of a connector assembly having multiple rows of spring chambers.
