A New Concept For Integrated Guidance and Drive of Railway Running Gears

Kurzfassung

Actively applying a relative torque which interacts with the relative rotation of the wheels of an axle provides both the increase of running stability at high velocities and steering of the vehicle with decrease of friction power and thus wear in curves. For vehicles with single-wheel drive the relative torque control can be combined with the traction control by an integrated approach including the estimation of feedback signal which cannot be measured directly. These capabilities are presented by simulation and experimetnal results, performed with a two-axle vehicle on a 1:5 scaled roller rig.
