→Each semitrailing link has an additional short link fixed to it, which causes axial displacement of the semitrailing link on its rotation axis during suspension movement, see figure.
→Plane semitrailing-link suspension is thus turned into three-dimensional wheel suspension with body-fixed instantaneous axis of rotation.
→In the present example, use of the extra link →the sweep angle ↓, braking and accelerating support angles ↑, without compromising on the change of position of the roll center during cornering, → favorable from the point of view of preventing of the bottoming-out effect.
