Description

Technical field

BACKGROUND OF THE INVENTION The present invention relates to articulated wagons for combined freight transport, in particular road vehicles, in which parts of the conveying surface, such as the ccz loading surface, are movably mounted vertically and the faces are movable horizontally on a bogie or trolley. or semi-trailer tractors may be transported and loaded and unloaded without any auxiliary means.

BACKGROUND OF THE INVENTION

The known combined freight wagons have extremely small wheels under the load area, which are subjected to high dynamic stress and high wear. DE 42 36 161 A1 discloses a carrier wagon for combined freight transport which is equipped with normal freight wagons and has in its middle part a plurality of lowerable partial load surfaces connected to one another. Because of the permissible contour of the vehicle, this carrier may carry only one lorry or one trailer or, in the most favorable case, one semi-trailer.

It is an object of the present invention to provide a combined freight wagon which, by a special solution of the fronts of the cargo (lorries, containers, etc.) of the receiving middle part and its connection with the carrier bogies and special solution and mutual alignment / arrangement of the vertical support and in order to transport all cars permissible in terms of their dimensions and their mass. The chassis of this wagon should have little wear, i. j. long maintenance cycles and long service life.

SUMMARY OF THE INVENTION

The object of the invention is achieved by an articulated wagon for combined freight transport, in particular of road vehicles, in which parts of the conveying surface as a loading surface are mounted movably vertically through lifting mechanisms and parts of the faces movable horizontally on a bogie or trolley. in the vertical plane, it can only break at the joints that connect the two parts of the intermediate carriage, and are interconnected with the interconnected interconnectors horizontally by means of arc guides, and thus the articulated car forms a vertically stationary platform from one joint to the other; the arc guide is less than the distance of the support points on the chassis / trolley and the arc guide is made flatter or curved and / or the outermost point of the arc guide is selected and arranged on the center line of the wagon with a different distance.

According to a preferred embodiment, the intermediate bridge can be connected to the front part via lifting mechanisms, such as a lockable articulated mechanism, by means of gears, and thus the intermediate bridge is designed to be lowered and / or retractable, thereby maintaining extreme contour profiles of vehicles in narrow tunnels. .

The loading area in the interspace trough can be equipped with known lifting mechanisms for loading and unloading.

The joints can be arranged in the longitudinal direction by sprung by known devices.

The articulated vehicle constructed in accordance with the present invention is formed in a horizontal plane rotatable and immovable in a vertical plane. The horizontal dials and the vertical support points on the bogies shall be selected so that, when the articulated vehicle is in operation, its contour is satisfactory on its lowered load surface. For a special-purpose articulated wagon, it can be lowered in its middle lower part. The start can be canceled when driving with a normal contour profile.

The invention is illustrated in the drawings by means of two exemplary embodiments.

DETAILED DESCRIPTION OF THE INVENTION

Fig. 1 shows an articulated wagon 1 which consists of an intermediate bridge 6 and a left and a right part of the intermediate wagon 4. The intermediate bridge 6 is designed to receive the loads to be transported. In the example shown, it is a truck 9. The intermediate parts 4 consist of two parts which are connected vertically by a movable joint 2 and form a fixed unit horizontally. The intermediate carriage 4 relies on the bogies 3 at the support points A. It is conceivable and within the meaning of the present invention that the intermediate carriage 4 itself will be a bogie and can take on the same tasks. The intermediate bridge 6 is articulated to the intermediate carriage 4 via an arc guide 5, so that the intermediate carriage 4 and the intermediate bridge 6 are rotatable relative to one another. In the embodiment of FIG. 5, this known arc guide is designed as a rolling guide with rolling bearings. The roller bearings 12 are arranged between the intermediate carriage 4 and the intermediate bridge 6 and guided and held in a known manner, whereby the shear and compression forces can be transferred from the intermediate carriage 6 to the intermediate carriage 4 and vice versa. The arc guide 5, shown as a roller bearing guide, can also be designed as a known chain transmission for the purposes of the present invention. By means of these arc guides 5, the intermediate bridge 6 in the rail curve can be brought to the position required for the calculation of the constraints. This is achieved by structurally distributing the components that determine the notional turning points B, for example by changing the curvature of the arc guide 5 itself. Also, the outermost point of the arc guide 5 can be displaced along the longitudinal axis on the intermediate carriage 4. The intermediate bridge 6 comprises for all road vehicles a suitable loading area 7, which is partially visible in FIG. 1. The rigidity of the articulated wagon 1 over its entire length is always achieved between the joint 2 on one side and the joint 2 on the other side. Thus, the entire articulated wagon assembly can only be articulated vertically in the hinges 2. The loading surface 7 is designed with height adjustment, for example by means of the air cushion technique according to DE 42 36 161 A1, with known devices not shown in the drawing.

In FIG. 2 shows the advantageous effect of the fictitious turning points B and the resulting position of the theoretical guide points, intersections E with the central axis C of the rail curve, on reaching a long load area. The top view shows the articulated wagon 1 in an exaggerated narrowly illustrated arc with the central axis C of the rail curve. The intermediate wagons 4 are coupled via the hinges 2. Both parts of the intermediate wagons 4 with their common longitudinal axis F (FIG. 2) form a secant of the central axis C of the rail curve. The intersection is the opposite point A on the bogie / trunnion pivot 3. The arc guide 5, which vertically rigidly connects the intermediate carriage 4 to the intermediate bridge 6, determines the imaginary point B of the pivot. This is the intersection of the two axes, which at the same time represent the longitudinal axis F of the intermediate carriage and the longitudinal axis D of the cargo surfaces. The distance of the intersection point E on the central axis C of the rail curve determines the profile limitation in the load area 7.

Fig. 3 shows a special variant of the articulated wagon 1 in a side view. This variant is suitable for freight transport in a narrow tunnel profile. There is a great cost to enlarge the upper section of the tunnel gauge, but lower when widening the mine. For this reason, in this variant of the articulated wagon 1, the central part of the articulated wagon 1, the intermediate bridge 6, is lowered when passing through narrow tunnels in the lower, widened tunnel cross section. On other lines to which the vehicle has a large gauge profile, this lowering is canceled again. The left side of FIG. 3 shows this normal state. The articulated wagon 1 with a hinge 2 and a bogie 3 is connected to the intermediate carriage 4 by an arc guide 5 with an intermediate bridge 6, exactly as in the basic variant. However, the spacer 6 is divided near both ends and is provided with a face piece 11 and is immovably connected to one another by means of lockable lever mechanisms, in the illustrated example of the hinge mechanism 8, and is designed to be liftable and lowerable by means of gears. Known guiding and connecting elements can also be used for this purpose. The right side of FIG. 3 shows a lowered intermediate bridge 6 for driving in a narrow tunnel, which is achieved by pivoting the lockable articulated mechanism 8 down by the gears 10.

Fig. 4 shows an extension according to FIG. 3 shows a part of the articulated wagon 1 in the loading position. Corresponding to the initial variant of FIG. 1, the hinges 2, the bogies / travels 3, the intermediate carriage 4 and the arc guide 5 are arranged. 3, the separation of the intermediate bridge 6 and the lockable hinge mechanism 8 are modified in such a way that the intermediate bridge 6 can be lifted up to the loading position. As a result, the loading surface 7 can be rigidly connected to the spacer 6.
