The main patent relates to an articulated rail train under the central joint of the car bodies arranged pivot-less, multi-axis drive, with the frame of each end of it assigned car bodies for the vertical adjustment of the drive in the track curvature is articulated. Furthermore, according to the main patent, when using small wheels for the drive, whose running circle diameter is e.g. reduced to about 600mm, the ends of a horizontally diagonal stiffener Undercarriage frame that keeps the wheel sets or fixed axles of the same backlash-free with the associated Car body only connected via the suspension spring system, over which the car bodies are located support the drive frame. The two longitudinal webs of the drive are solely through the wheel sets or the fixed axles connected, which are mounted in the webs by means of zero-play roller axle bearings, so that the longitudinal webs with the axes result in a horizontally diagonally rigid drive frame. this has generally a prerequisite that special bearings are used in which the mutual distance the roller and cage assemblies are large enough to allow a sufficiently long lever arm between the axle to yield to the two roller rings.

But if the load capacity of the wagons is increased or the articulated train is to travel on routes, on where only a low axle pressure is permitted, the number of axles per car must be increased. Accordingly, instead of those shown and described in the exemplary embodiments of the main patent biaxial drives multi-axis are used. In this case, however, the Task, even with a multi-axis drive, the same vertical pressure on each wheel is applied to the support to convey the tracks and to guide the wheels of the middle axles in the intersection gap.

The first additional patent solves this problem in that when more than two axes are arranged in a drive according to the main patent, two suspension spring systems supported on the same are provided on each drive longitudinal side via a device for evenly distributing the pressure on all wheelsets of the drive. The design is made in such a way that the suspension springs are supported in hydraulically connected cylinders by means of pistons at the ends of the running girders. The cylinders of the springs are hydraulically connected to cylinders, the pistons of which act on the middle wheel set or sets from above. By mounting the springs and the central wheel sets via pistons and cylinders, which are connected to one another by lines under the central joint of the car bodies

hydraulic axle pressure compensation is achieved with the multi-axle drive.

This means that a multi-axle or three-axle drive controlled in the curved track is also available for articulated trains created small wheels, which has proven itself through good and safe running. Only the hydraulic one Pressure equalization on the axles of the drive has not proven itself in the rough railway operation and fails after a short time. Now the task arose, with the three-axis drive of the additional patent, which showed very good running properties, the hydraulic pressure equalization by a suitable one replace mechanical; but the fixed guidance of the three wheel sets with small wheels in a diagonally stiff drive frame and the small center distance, which have proven themselves, absolutely can be achieved.

Three-axle bogies or bogies are used for wheels with a normal running circle diameter known, in which the pressure equalization takes place in that the drive frame on the middle Wheelset is designed to be vertically foldable and the suspension springs to form compensating levers accordingly are arranged on the drive frame. It is z. B. each part of the two-part side support of the Drive frame with its outer end gooseneck-like on the bearing bushing of one of the end wheel sets and with its inner end, the bearing bush
