Description

Two-axle rail freight wagon

Technical field

The invention relates to a two-axle rail freight wagon for the transport of containers and / or transport boxes with two outer longitudinal beams, at least one middle longitudinal beam and longitudinal beams connecting the cross beams, at least several cross beams being provided with support pins for stabilizing the containers and / or .

BACKGROUND OF THE INVENTION

Such two-axle rail freight wagons with a wheel diameter of 920 mm are known in various embodiments. The purpose of the invention was to transform these known rail freight wagons to be suitable for the transport of higher loading units.

SUMMARY OF THE INVENTION

The solution according to the invention is characterized in that the longitudinal beams are articulated downwards to form a low loading plane between the axles, lowered relative to the higher loading plane above the axles, and that at least two cross beams consisting of a bridge and two arms are arranged in the low loading plane. which are tilted about a horizontal axis passing through the ends of the arms between a horizontal, below a low loading plane lying position and a perpendicular position, in which the bridge abutment surface of this transverse beam is flush with the higher lying loading plane of the rail freight wagon.

This transformation of the two-axle railway wagon with a wheel diameter of 920 mm according to the invention makes it possible to transport not only normally high loading units on a higher lying, in the central region of the rail freight wagon, the loading plane between the axles. In this case, the tilting crossbeams are tilted in their horizontal position so that both lie below the low loading plane.

While, for two-axle freight wagons with a wheel diameter of 920 mm, it has so far been possible to transport only loading units up to 2670 mm on the European double-track network code number C 22 on a higher loading platform lying 1180 mm above the upper edge of the rails. of the invention the possibility to transport on a low loading plane lying max. 700 mm above the upper edge of the rails, loading units up to min. 3150 mm. By allowing two-axle freight wagons with a wheelbase of up to 10 m, higher loading units of up to 8.25 m in length can be carried.

In a preferred embodiment of the invention, the longitudinal beams are connected in addition to the end-arranged front beams and at least two hinged cross beams with at least two cross beams in the region of each axle, two cross beams in the crank region and three cross beams in the low load region, in the middle of the wagon. In this way, the required torsional stiffness and thus the necessary safety against derailment are displayed even with a rail freight wagon over a bumper greater than 15.5 m.

In the case of two-axle wagons according to the invention, the axles of which are suspended by means of spring tails on the vehicle chassis, the vehicle chassis can be formed with the required torsional strength at minimum weight, which ensures the necessary derailment safety even over long wagons and large diameters. wheels. In accordance with a further feature of the invention, in order to avoid adverse force effects in the region of the vehicle bogie, in accordance with a further feature of the invention, the inner springs of each axle of each axle are shifted two above the transverse chassis of the vehicle chassis, which connect the external longitudinal beams in the bending region together.

In contrast to the support of the tailstock by only one transverse beam, which leads to torsional stress on the lateral support, this support of the inner tailstock of the spring in the crank region according to the invention prevents the two laterally superposed transverse beams of the vehicle. vehicles. Instead, only the bending forces are transmitted to the superimposed transverse beams from the inner tines of the spring so that the vehicle chassis can be economically formed in the region of the outer longitudinal beams without damaging the load capacity and torsional strength of the vehicle chassis.

In a preferred embodiment of the invention, transverse beams arranged in the region of the kink and connected to the inner tailstocks of the spring are formed as hollow beams.

In order to be able to load the higher loading units also by means of a gripping tool, according to a further feature of the invention, the outer longitudinal beams are arranged at a distance which is greater than the largest width of the loadable containers or transport boxes. This is preferably 2680 mm, so that higher 20-foot containers and transport boxes of size 3 with 8.05 m in length can be transported on a low stowage plane within the prescribed boundary profile.

Instead of one loading unit up to 14.9 m (49 feet) or two loading units up to 7.42 m (20 feet), 30- and 40-foot containers respectively can be transported. Finally, it is proposed by the invention to provide support pins - also on tilting cross beams - retractable so that they can move away from the respective loading plane when not in use.

DETAILED DESCRIPTION OF THE INVENTION

The two-axle, two-axle 1-equipped rail freight wagon has two outer, straight-running longitudinal beams 2, which are articulated downwards between the axles and consequently form in its central region a low loading plane L lowered relative to the normal loading plane L. In a preferred embodiment, the normal loading plane L lies above the upper edge of the rail SO when using a wheel diameter of 920 mm, 1180 mm. In contrast, the low loading plane is 700 mm above the upper edge of the SO rail. These different heights of the loading planes are well visible even when comparing FIG. 3 and 4.

In the exemplary embodiment, the rail freight wagon comprises two central longitudinal beams 2 in the region of the normal loading plane J, above the axles 1, and in the region of the low loading plane L _z there is only one central longitudinal beam 4. more crossbeams as well as end beams at the ends 5.

As shown in particular in FIG. 2, the two longitudinal beams 2 are connected to the central longitudinal beams 3 by way of example by means of two transverse beams in the region of the axles 1.

6. Also in each transition region between the normal loading plane L and the low loading plane L _, two transverse beams 7 are arranged at each time. · In the low loading plane L _{2 area} , the outer longitudinal beams are connected to the middle longitudinal beam 4 together with three cross beams 8 of which the middle lies in the middle of the wagon. All of these crossbeams 6, 7 and 8 are rigidly connected to the outer longitudinal beams 2 and the middle longitudinal beams 3 and 3, respectively. 4_.

On each side of the crossbeam 8 lying in the center of the wagon there is at each time another crossbeam 9 which is U-shaped and therefore comprises a bridge 9a and two arms 9b. At the ends of the arms 9b facing away from the bridge 9a, each transverse beam is tiltable about the horizontal axis 10, which is shown in FIG. In this way, each crossbeam can be tilted from its perpendicular position shown in Fig. 1 by 90 ° to a horizontal position, as indicated by the arrows in Fig. 1.

In order to stabilize the containers and / or the transport boxes by the above-described rail freight wagons, the support pins 11, which are shown in a side view in FIG. 1, are shown in cross-section according to FIG. These support pins 11 are predominantly designed to be retractable or tilted so that they do not interfere with the loading of the rail freight wagon when not in use.

With this rail freight wagon, normally high loading units (containers or transport boxes) can be transported on a normal loading plane. In this case, the tilting crossbeams 9 are folded to a perpendicular position according to FIG. If the containers are moved above or carrying cases, the fold in the cross-members 2 from the position of Figures in the rest position, in which the low lying below the loading plane S ₂ · In this position, may be loaded to a low loading floor _of the railway L cargo wagon higher loading units.

The overview in FIG. 5 shows the various options for loading a rail freight wagon. It can be seen that one higher 20-foot CT 20 ¹ container can be transported on the low loading plane. a transport box of size 3 WB 3 with 8.05 m length, the loading units according to FIG. 4 lying inside the boundary profile. Two 20 foot CT 20 'containers or two 1 WB 1 or size transport boxes can be carried on the normal loading plane. 2 WB 2 up to 7.42m length, resp. one container each between 30 ft. CT30 'to 49 ft. CT 49 *, respectively. one transport cabinet size 3a WB 3a or size 4 WB 4 up to 14.9 m long.

According to FIG. 6, each axle 1 is mounted at the ends in a shaft bearing housing 12, which is guided in a vertical direction between two shaft holders 13 and fixed to the underside of the support spring.

This support spring 14 is hinged at each end by a collar 15 of the spring to the tailstock 16 and 14 respectively. 17 spring. These spring ties 16 and 17 are connected to the vehicle chassis.

While the outer tail of the spring 16 is located towards the end of the chassis of the vehicle on the lower part of the crossbeam 6, each of the spring tails 17 is supported by two crossbeams 7 in the region of the outer longitudinal beams. As a result, these transverse beams 7 which are disposed one above the other are only bent on the bend. In this way, torques are prevented from being introduced into the chassis in the region of the bend of the outer longitudinal members.

As can be seen in particular from FIG. 6, the transverse beams 6 and 7 are designed as hollow profiles so that a high torsional stiffness of the vehicle chassis is achieved with low dimensions and low weight.
