Abstract
The present invention pertains to the connection of two multi-axle running gears into a running gear group for rail vehicles with low-lying platform, wherein the running gears have at least two wheel sets with small wheel base and a running gear frame consisting of side walls and crossbeams betweenn two axles. The wheel sets are mounted in the running gear frame via axle bearings, and each running gear is connected to the platform with false pivot only via a leaf spring and link suspension located transversely in front of and along each side wall. To ensure that the correct turn-out angle of each running gear and each running gear group is freely guaranteed during cornering, and at a correct axle load equalization of the running gears of each running gear group is ensured. The running gears of each running gear group are connected via a connecting beam that is arranged in the middle of the length of the running gears and is hinged on same, wherein the connecting beam is guided centrally with a clearance between guide brackets of the platform. The ends of each leaf spring of the running gears of each running gear group, which ends face each other, are connected to one another via their links by an equalizing lever, which is mounted on a bracket of the car bridge.
