Intermediate regions are provided between straight and circular-arc slide sections having a curved sliding surface in cross-section, the intermediate regions being clothoid-shaped in top view. In an intermediate region, which starts with a quarter-elliptic cross-section of the sliding surface at the outer side of the curve corresponding to the cross-sectional shape of the straight slide section, the ratio between the major and the minor axes of the ellipse continuously changes towards the other end so that individual trajectories depending on the velocity of the vehicle form in top view a sheaf of clothoids having the same initial point. The individual structural elements of the slide are flanged at their ends, one flange, each, of two structural elements being adjustable in various directions and supported by a strut. |
