Abstract

In order to be able to use a railway fleet car which is of lightweight and economical design universally within a train configuration both as an end car and as a central car, it being possible for a customary UIC coupling interface to be made available as required at each end of the car, the end regions of the underframe (1) are of identical design without permanently connected buffer brackets and a receptacle bearing (2) is arranged in each end region of the underframe (1) at the same distance from the end side in the vertical longitudinal centre plane, by means of which receptacle bearing (2) either a coupling rod (3) or a buffer bracket (4) with draw and buffer gear (5) can be releasably attached to the underframe (1) and supported therewith. <IMAGE>

Description

Technical field

The invention relates to rail freight wagons, in particular flat wagons with a bogie, the end regions of which are provided with one running gear.

BACKGROUND OF THE INVENTION

German-Laid-Open DE-AS 2245594 discloses, for example, the interconnection of freight wagons of the same type and their inclusion in an entire train for the transport of generally the same loads. The individual rail freight wagons are provided with a bogie, on each side of which a towing and impact device is mounted so that it is also possible to assemble these rail freight wagons into a mixed, conventional train group.

DE-OS 3801117 also discloses a traction unit with a continuously low-floor floor of a wagon mainly for the transport of road freight vehicles, comprising at least one rail freight wagon with a chassis provided with at least one turntable, adapted for front loading and unloading. from at least one other wagon, all the wagons of the towing unit being connected together by short couplings.

The wagon pair formed by the end wagon and the trailer wagon is connectable by a short coupler with the other pair into one traction unit using a low bumper.

Because this train set is made up of rail freight wagons of different construction, end wagons, trailer wagons and optional side bridges are modified, the universal welfare of the freight wagon is limited, which means the particularly popular formability and disconnectability in the train set, as the unit it consists of one end wagon and one trailer wagon which is not separately usable due to the lack of a separate running gear on the trailer side. Also, the end carriage is not self-service, since the trailer side is provided with a travel device in a Jacobson arrangement, and consequently there is no connecting center point. At the free ends of the end carriage and the trailer carriage, tilting heads are provided with a towing and impact device for loading from the front.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a rail freight wagon, particularly a flat wagon, in such a way that its construction is light, economical and capable of being integrated into a train set not only as an end wagon but also a medium wagon and each wagon as required. universally disconnect coupling point.

The above-mentioned task is feasible by the solution according to the invention.

SUMMARY OF THE INVENTION

The subject of the invention are platform wagons with a bogie, railway freight wagons, in particular whose end regions are provided with one running gear and the essence is that the end regions of the bogie are of the same construction without a rigidly connected bumper bracket. spaced from the front side, a bearing in a vertical longitudinal plane, by means of which the coupling or bumper bracket with the towing and bumper device as the central ram coupler or universal coupler is capable of detachable, snap-fit, rigid connection to the bogie.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention will now be described with reference to the following illustrated examples, in which:

Fig. 1 is a plan view of a free end region of a rail freight wagon with a buffer bracket mounted;

Fig. 2 is a plan view of the ends of two interconnected rail freight wagons.

DETAILED DESCRIPTION OF THE INVENTION

The rail freight wagon comprises a bogie 1 in which both end regions are located in a longitudinal median plane one catch bearing 2. The catch bearings are arranged at equal distances from the respective front sides of the bogie 1. Optionally, the catch 3 can be detachably attached and engaged with the coupling 3 or bumper bracket 4.

In FIG. 1 shows the free end region of a railway freight wagon with a bumper bracket 4 mounted with a towing and impact device 5, in this example with two buffers and a universal hook coupling.

The bumper bracket 4 is provided with a cantilever beam 6 and a support beam 7 on each longitudinal side. The support beams 7 extend beyond the cantilever beam 6 in the direction of the median transverse plane of the bogie 1a. In order to accommodate the vertical moments, four locking devices 9 are mounted in the separating plane between the bumper bracket 4 and the bogie 1. of which at least two are located in the different transverse planes of the bogie 2. in the bearing plane between the cantilever beam 6 and the front side of the chassis 1, there are two remaining securing devices 9.

In FIG. 2 shows two end regions of two freight wagons connected to one another. The link 3 connects the two rail freight wagons by means of catching bearings 2. The front sides of the chassis 1 have no buffer brackets 4 at their facing ends and are kept at a distance by the link 2.

In certain cases of alignment, for example to reduce the impact energy impacted by the load, it is expedient in this case to replace the rigid link 2 itself with a simple traction and support device.

The disconnection of the two freight wagons is carried out by unilaterally releasing the joint in the gripper bearing 2 of the freight wagon.

The link 2 either remains at one end of the wagon or is completely removed by loosening the other joint in the catch bearing 2 of the other wagon.

The connector 2 may also be at a separation point. For this purpose, the releasably designed purpose is a separating point established in the middle of the connector 2, since the capability for universal alignment at the ends and not having to be carried out thereafter, results in a greater number of the same wagon additional work effort.

A sophisticated train set consists of at least two rail freight wagons as described above, the wagons of this train being provided at their free ends with a detachably attached bumper bracket 4 and the ends of the wagons facing each other and, in this case, the other medium wagons connected by a link 2
