Abstract: 1. Two-wheeled bogie for track-guided vehicles with a traction-supported steering device and with a wheel mount, both wheels (4, 4') are mounted on the common wheel mount (3) the wheels are arranged substantially parallel to each other on a notional connecting line extending perpendicular to the wheel circumference and at a substantially constant distance from one another, the wheel mount (3) has two vertical pivoting axles (2, 2') outside the wheel contact points wherein only one pivoting axle is mounted on each side of the wheel mount (3), which can be moved and locked in the horizontal plane in accordance with the curvature of the curved track and the wheel mount (3) can be steered about the axle. 2. Two-wheeled bogie according to Claim 1, wherein said pivoting axles (kingpins 2 and 2') of the wheel mount (3) can be moved along the curved section (details 5 and 5') of the wheel mount wherein said curved section is arranged longitudinally on the frame (1) of the wheel mount. 3. Two-wheeled bogie according to Claim 1 or 2, wherein vertical pivoting axles are formed by kingpins (2, 2'). 4. Two-wheeled bogie according to any of the preceding Claims, wherein said vertical pivoting axles are provided with spring elements and/or guide rods enabling a turn around, essentially, vertical axle. 5. Two-wheeled bogie according to any of the preceding Claims, wherein one vertical pivoting axle can be fixed individually in any required place of the curved section (details 5 and 5') of the bogie, while the other vertical pivoting axle remains in the initial position. 6. Two-wheeled bogie according to any of the preceding Claims, wherein said wheel mount (3) can turn so that the wheels (separately 4 or 4') always turn and/or directed radially towards the curved track along which a guided vehicle moves. 7. Two-wheeled bogie according to any of the preceding Claims 2-6, wherein said vertical pivoting axle (kingpin 2 or 2') of said wheel mount (3) can be fixed on the curved section of the wheel mount using removable cross section made of a spring and a damper, when they are interlocked. 8. Two-wheeled bogie according to any of the preceding Claims 2-7, wherein said vertical pivoting axle (kingpin 2 or 2') of said wheel mount (3) can be fixed on the curved section (details 5 and 5') using an electromagnetic and/or mechanical locking means. 9. Two-wheeled bogie according to any of the preceding Claims 2-7, wherein said vertical pivoting axle of said wheel mount (3) can be fixed on the curved section of the bogie using a connection threaded coupling/spindle driven by an electric motor 10. Two-wheeled bogie according to any of the preceding Claims 2-9, wherein said vertical pivoting axle of said wheel mount (3) can move along the curved section of the bogie using different draw efforts of wheels (4 and 4') with separate drives. 11. Two-wheeled bogie according to any of the preceding Claims 2-10, wherein said vertical pivoting axle of said wheel mount (3) can move along the curved section of the bogie using pneumatic and/or hydraulic driving means. 12. Two-wheeled bogie according to any of the preceding Claims 2-10, wherein said vertical pivoting axle of said wheel mount (3) can move along the curved section of the bogie using a connection threaded coupling/spindle driven by an electric motor. 13. Two-wheeled bogie according to any of the preceding Claims 2-12, wherein said vertical pivoting axle of said wheel mount (3) can move along the curved section of the bogie using a toothed wheel driven electrically or by an engine, said toothed wheel meshing with toothed rim arranged along the curved section of the bogie. 14. Two-wheeled bogie according to any of the preceding Claims 1-13, wherein said wheel mount (3) can turn around the vertical pivoting axle, which arranged on the outer side of the curvature. 15. Two-wheeled bogie according to any of the preceding Claims 1-13, wherein said wheel mount (3) can turn around the vertical pivoting axle, which arranged correspondingly on the inner side of the curvature.
