  • Patent number: 5469792
    Abstract: Railborne vehicle comprising a gantry bogey, provided between mutually opposite ends of two successive carriages. A bottom plate 1, 2 projects from each of both carriage body ends to form a passage between the carriages. The two bottom plates 1, 2 are interconnected by a joint, preferably a spherical joint 3. In order to transmit the forces resulting from lateral torsional deformations of the carriage superstructure when negotiating curves and arising from uneven tracks, the bottom plates 1, 2 are interconnected by connecting beams 11 which are flexible and torsionally deformable and are connected at their ends by resilient connections to the bottom plates 1, 2.
