1. vehicle suspension system is characterized in that it comprises:

  • Two front wheel side shock absorbers (20 that all comprise first absorber chamber;

         22) two rear wheel-side shock absorbers (24 that and all comprise second absorber chamber;

         26);

    Said front wheel side shock absorber (20,22) and said rear wheel-side shock absorber (24,26) are arranged on four corresponding wheel-side member (40) of four corresponding wheels of rotatably support and are positioned between corresponding four the corresponding body-side member of wheel-side member on the body side and corresponding (40) (42);

    WithControl cylinder (30), it comprises piston component (72) that (a) forms through utilizing union lever (78) that two pistons (74,76) are linked each other and (b) has a cylinder body (70) of two cylinder chambers that separated by partition wall (88);

    Wherein, said union lever (78) fluid-tight ground with run through said partition wall (88) and said two pistons (74 slidably;

         76) fluid-tight ground be entrenched in said two corresponding cylinder chambers slidably;

    Two inboard control cabins (160,162) are formed between said two corresponding piston (74,76) and the said partition wall (88) thus;

    Two outside control cabins (164;

         166) on that be formed on said two corresponding piston (74,76) and the side opposite external side said partition wall (88) placeIt is characterized in that said vehicle suspension system also comprises;

    Connecting path;

    It is connected first absorber chamber of said two front wheel side shock absorbers and the side in corresponding two outside control cabins (164,166) and corresponding two the inboard control cabins (160,162);

    And second absorber chamber and corresponding two outside control cabins (164 with said two rear wheel-side shock absorbers;

         166) and the opposing party in corresponding two inboard control cabins (160,162) be connected, whereinSaid front wheel side shock absorber (20;

         22) and the attenuation characteristic of said rear wheel-side shock absorber (24,26) and be used for said inboard control cabin (160,162) and said outside control cabin (164;

    The compression area of said piston component (72)

         166) is configured to;

    Make when Vehicular turn, said piston component (72) the commitment that turns to promptly when the moving direction of inclination speed hour and said piston component (72) opposite at the moving direction in other stage that turns to, and whereinThe direction that said piston component (72) moves at the commitment that turns to is the direction of said Vehicular turn.
