  • Patent number: 6418858
    Abstract: A method for the drive coordination of a rail-guided vehicle with individual-wheel drive traveling on straight track, including the steps of determining a differential speed (&Dgr;n) of opposite track wheels and a control value (&Dgr;M) by a controller as a function of a set point, whereby the set point is ideally zero and the frequency and the damping of the control value (&Dgr;M) can be dynamically adjusted by controller parameters. The invention further comprises a method for the drive coordination of a rail-guided vehicle with individual-wheel drive, in particular when the vehicle is traveling over curves, in which at least one axle is fastened so that it can rotate with respect to the underbody, whereby the angular position (&ggr;st) of the axle with respect to the underbody is regulated so that the track wheels are tangential to the rail by setting the angular position (&ggr;sl) of the axle by means of the torque set points (MSet,l MSet,r) of the individual wheel drives.

  • Patent number: 6038981
    Abstract: A two-wheeled running gear for a track-guided vehicle comprising a running gear frame; a wheel carrier; first and second wheels coupled to opposite sides of the wheel carrier; first and second vertical pivot pins, the first vertical pivot pin coupled to the first side of the wheel carrier and movably connected to the first side of the running gear frame, the second vertical pivot pin coupled to the second side of the wheel carrier and movably connected to the second side of the running gear frame, the first and second wheels located between the first and second vertical pins; and means for controlling a movement of the first pivot pin relative to the running gear frame such that, during a curved track drive, the first pivot pin can be held substantially in place relative to the running gear frame while the second pivot pin can move relative to the running gear frame so that the line connecting the centers of the wheels is maintained substantially parallel to the radius of curvature of the track.
