Patent ID: 6988718

Claim:
A wheel-guiding spring strut with internal level regulation connectable between upper and lower support structures, comprising: a self-pumping hydropneumatic spring strut having a piston rod; an upper supporting bearing connectable to the upper support structure and dimensioned and arranged for supporting an upper end of the piston rod of the spring strut relative to the upper support structure, the piston rod being cardanically movable relative to the upper supporting bearing; a spring plate fixed to a surface of the upper supporting bearing and having a center axis normal to a plane of the spring plate, the spring plate being arranged so as to be cardanically movable relative to the piston rod; and a coil spring fixed between the spring strut and the supporting bearing at the spring plate, the supporting bearing being asymmetrically deformable in response to axial loading by at least one of the piston rod and the coil spring such that the center axis of the spring plate pivots outward relative to a longitudinal axis of the piston rod and the surface of the upper support bearing follows the pivoting movement of the spring plate.
