Die Längsachse des Motors liegt dabei parallel zu den Querträgern und fluchtet mit der Achse der Gelenke der jeweiligen Radschwinge. Das Getriebegehäuse ist an der axial innenliegenden Gabelhälfte der Radschwinge befestigt. Da der Motor mit seinem Getriebe axial innen liegt, ist im Bereich der Radkästen eines Schienenfahrzeugs kein Niederflurbereich möglich. Auch der gemeinsame Antrieb von zwei in Längsrichtung hintereinander liegenden Einzelrädern ist nicht möglich.EP 0 571 961 A1 is a running gear for rail vehicles known, which consists of two parallel side members, which are connected by two cross beams. To the Each end of the side members is a fork-shaped wheel swing arm articulated, in their fork a single wheel is rotatably mounted. Each single wheel is powered by a motor driven with spur gear, the motor housing on Gearbox is attached. The longitudinal axis of the engine lies parallel to the cross beams and aligned with the Axis of the joints of the respective swing arm. The gearbox is on the axially inner fork half of the wheel swing arm attached. Because the motor with its gearbox is axial is in the area of the wheel arches of a rail vehicle no low floor area possible.

Bei dem in die Radschwinge integrierten Getriebe kann es sich z.B. um ein Winkelgetriebe handeln. Weiterhin kann das Getriebe auch mehrstufig ausgebildet sein, wobei auch eine Kombination von Winkelgetriebe und Planetengetriebe möglich ist. Bei einer Ausgestaltung ist es in vorteilhafter Weise möglich, jeweils eine oder mehrere Getriebestufen in jede Gabelhälfte zu integrieren.In the chassis according to the invention, at least two, a pair of wheels forming individual wheels of one motor each are driven.
