Description

The invention relates to a rail freight wagon with a multi-part sliding wall, the wall parts of which lie in the closed position in one plane and can be moved laterally out of the closing plane for section-wise opening of the wall and can be moved in a common displacement plane by the wall parts remaining in the closing plane in the longitudinal direction of the wagon.

Such rail freight cars are known in various designs. Either there are only two sliding wall parts that can only be moved alternately out of the closed position and moved in the sliding plane to release the loading opening, or they are very complex constructions with the help of which the wall parts of an at least three-part sliding wall from the closed position can be moved out and moved in the sliding plane on support and guide rails in the longitudinal direction of the rail freight wagon.

The invention has for its object to provide a rail freight wagon with a multi-part sliding wall of the type described in the introduction, the wall parts of which are held and locked in the closing plane with simple and thus inexpensive to manufacture and robust means, moved between the closing and shifting levels and in the shifting level to release Loading openings can be moved without the need for complex support and guide devices and complicated control mechanisms.

The solution to this problem by the invention is characterized in that the wall parts which are guided on their upper edge in the sliding position and lockable in the closed position are supported with their lower edge on bearing elements which enable both sliding in the sliding plane and transfer between the sliding plane and the closing plane .

According to a further embodiment of the invention, these bearing elements are designed as a slideway that encompasses the entire width of the displacement plane, the closing plane and the distance between them, which is either continuous over the entire length of the carriage or consists of sliders spaced apart along the entire carriage length. The slideway or sliders are made of a slidable material, for example of self-lubricating plastic.

According to a further feature, the bearing elements can also be designed as rollers distributed over the entire length of the carriage, the axis of rotation of which lies transversely to the direction of displacement, the width of which comprises the entire width of the displacement plane, the closing plane and the distance between them, and each of which can be rotated independently of one another Roll sections are divided.

The bearing elements are extremely simple in both design options, so that they can be produced inexpensively and in a robust design, the use of rollers having the additional advantage that, in particular when the wall parts are displaced longitudinally in the plane of displacement, only slight frictional forces can be overcome.

In the slideway or between the sliders or the rollers, slides are arranged which enclose the wall parts at their lower edge in a fork shape and are movably supported between the closing plane and the displacement plane. By means of these slides, the wall part to be opened or closed can be transferred in a simple manner between the shifting plane and the closing plane.

According to a further feature, the slides assigned to a wall part in the closed position can be moved together by an actuating shaft, which can be rotated via a linkage by a hand lever. As a result, not only a synchronism of the slides to be operated together, but also a simplified handling is achieved.

The bearing elements can also consist of support rollers which are rotatably mounted in the displacement plane transversely to the direction of displacement and of transfer devices which are arranged between the support rollers and which are arranged at a distance from one another and which can be moved between the displacement plane and the closing plane by performing a lifting movement. As a result, the frictional forces are considerably reduced when the wall parts move between the closing plane and the displacement plane; In addition, the wall parts to be opened are moved in a controlled manner between the closing level and the shifting level.

In this embodiment of the bearing elements, the lower edge of the wall parts can be provided with a running groove for the support rollers and for the engagement rods of the transfer device. According to a further feature, the transfer device consists of levers which can be pivoted about an axis lying below and of an engagement rod which connects the free ends of the levers.

In a preferred embodiment of the invention, the support rollers can also be designed as flanged rollers and the transfer device can be designed as a crank lever articulated at one end on an actuating lever, which has a guide opening corresponding to the guide profile of the flanged rollers for the lower edge of the wall parts and a control curve with which they are mounted on a Support roller are supported. With this design, the transverse and lifting as well as the settling movement of the wall parts can be precisely adapted to the respective circumstances by appropriately designing the control curve. Also one in each

Curve levers assigned to the closed position of the wall part can be moved together by an actuating shaft which can be rotated by a hand lever via a linkage.

5 Irrespective of the special design of the bearing elements, the wall parts are provided on their upper edge with a guide profile which comprises a guide track and a guide rail which, in the shifted position of a wall part, engages in the guide track of the wall parts in the closed position, so that the wall parts located in the sliding plane are guided at their upper edge to the upper edge of the wall parts remaining in the closing plane. Sliding forks work together with the guide profile of the wall parts, through which the 15 upper edge of each wall part can be transferred between the closed position and the shifted position.

Finally, with an embodiment of the invention it is proposed to actuate the sliding forks assigned to a wall part in the closed position together and simultaneously with the slides or the transfer device via a linkage by means of a hand lever, so that the necessary synchronization also with regard to the upper edge and the lower edge of the wall part to be moved between the closing plane and the sliding plane is inevitably achieved.

point open the side wall of the rail freight car from this closing level in a movable in front of the closing level sliding plane in which the wall parts 5 can be moved in the longitudinal direction of the rail freight car. In Fig. 6, the wall part 5 shown with solid lines is in the closing plane and the wall part 5 shown with dash-dotted lines in the displacement plane.

On the one hand, to allow wall parts 5 to be transferred between the closing plane and the displacement plane and, on the other hand, to move wall parts 5 in the displacement plane, each wall part 5 is supported on bearing elements by means of its support profile 9, four of which are shown in FIGS. 2 to 5 are shown.

In the first embodiment according to FIG. 2, the bearing elements are designed as rollers 11 distributed over the entire carriage length, the axis of rotation of which is transverse to the direction of displacement of the wall part 5 and the width of which comprises the entire width of the displacement plane, the closing plane and the distance between them, as is the case with the Fig. 2 reveals. Each roller 11 is divided into two independently rotating roller sections lia, 1 lb. This enables the rear roller sections 1 la according to FIG. 2 to be able to support a wall part 5 located in the closing plane, regardless of whether a wall part 5 located in the shifting plane is moved in the longitudinal direction of the rail freight wagon on the front roller sections 1 lb, as is the case here with dash-dotted lines in Fig. 2 is indicated.

The continuous roller axle 11c in the embodiment shown in FIG. 2 is mounted between the lower long beam 7 and a support plate 12 which is fastened to the long beam 7 by two lateral support plates 13. In order to avoid an unintentional running of the support profile 9 on the rollers 11 during a sliding movement of a wall part 5, the front roller sections 1 lb can be provided with a small recess, as shown in FIG. 2. This screwing is designed in such a way that it enables a desired displacement of the support profile 9 in the longitudinal direction of the roller axis 11c after overcoming a slight resistance when the wall part 5 is out of the displacement. level should be transferred to the closing level.

In the second embodiment of the bearing elements according to FIG. 3, these consist of sliding pieces 14 which are spaced apart from one another along the entire carriage length and which are fastened to a bearing plate 16 by means of countersunk screws 15. This bearing plate 16 is in turn held between the lower long beam 7 and the supporting plate 12, which in turn is fastened to the lower long beam 7 by means of supporting plates 13. In this embodiment too, a slight lowering can be formed in the sliding pieces 14 in the region of the displacement plane, as shown in FIG. 3, in order to prevent the support profile 9 from being inadvertently moved out of the displacement plane.

Instead of individual sliders 14, which are spaced apart from one another along the entire length of the carriage, a continuous slideway 17 can also be provided, which runs over the entire length of the carriage. The cross section of this slideway 17 and its attachment corresponds to the illustration in FIG. 3. For this reason, reference number 14 in brackets has been added to FIG. 17.

In the above-described embodiments, the wall parts 5 are transferred between the closing plane and the shifting plane by means of sliders 18, which comprise the support profile 9 at its lower edge in a fork-shaped manner and which are movably supported between the closing plane and the shifting plane. In the exemplary embodiments shown in FIGS. 2 and 3, the slides 18 are for this

Purpose articulated on a crank arm 19 of an actuating shaft 20 which can be rotated by means of a linkage 21a, 21b, 21c by a hand lever 22 which is arranged in the region of a post 8 or an end wall 3, as can be seen in FIG. 7 5.

In the embodiment according to FIG. 4, a running groove 9a is formed on the lower edge of the support profile 9. By means of this running groove 9a, the support profile 9 is supported on support rollers 23 which are rotatably mounted in the displacement plane transversely to the displacement direction, as is shown with dash-dotted lines in Fig. 4. The wall parts 5 are transferred between the displacement plane and the closing plane by means of between the support rollers 23 arranged at a distance from one another. In the exemplary embodiment shown, these consist 15 of two levers 24a which can be pivoted about an axis below and an engagement rod 24b connecting the free ends of these levers 24a, the support profile of which is adapted to the profile of the support rollers 23 Actuation of the transfer device 24 is carried out by 20 a push rod 25 which is articulated according to the slider 18 on the crank arm 19 of an actuating shaft 20.

In the closing plane, the wall part 5 rests on the engagement rod 24b by means of its support profile 9, wherein the running groove 9a of the support profile 9 prevents slipping. To guide the wall part 9 out of the closing plane into the displacement plane, the actuating shaft 20 is rotated by the hand lever 22 in the manner described above. Here, the crank arm 19 reaches the position shown in FIG. 4 with dash-dotted lines, whereby the thrust rod 25 assumes the position also shown in dash-dotted lines. During this movement, the engagement rod 24b on which the wall part 5 rests is carried along. Since this engagement rod 24b is mounted on the levers 24a, it performs a movement on a circular arc during the transfer between the closing plane and the shift plane 35, the center of which is defined by the pivot axis of the lever 24a below and the radius of which is determined by the length of the lever 24a results. Overall, this not only results in a lateral displacement of the wall part 5, but also a 40 stroke movement, through which the support profile 9 moves from the closed position shown in solid lines to the shift position shown in dash-dotted lines, in which it moves with its groove 9a on the Carrier rollers 23 is located. These support rollers 23 enable a low-friction displacement of the wall part 5 in the displacement plane. The return of the wall part 5 from the displacement plane into the closing plane takes place in the reverse order, in that the transfer devices 24 located between the support rollers 23 lift the support profile 9 from the support rollers 23 and transfer them into the closed position with a lifting and lowering movement.

The last embodiment shown in FIG. 5 shows the use of flange rollers 26 in the region of the displacement plane. These flanged wheels 26 are also arranged at a distance 55 from one another and are rotatably mounted on the lower long beam 7 or a support plate 12 transversely to the direction of displacement. The conversion of the wall parts 5 between the closing plane and the displacement plane and the mounting of the support profile 9 in the closing plane takes place in this embodiment 60 by cam levers 27, which have a guide opening 27a corresponding to the guide profile of the flanged rollers 26. On the underside, the cam levers 27 are provided with a control cam 27b, with which they are supported on a support roller 28 which is rotatably mounted on the lower longitudinal member 7, specifically about an axis of rotation lying in the direction of displacement of the wall parts 5, as shown in FIG 5 reveals. The cam levers 27 are also articulated on the crank arm 19 of an actuating shaft 20, so that they rotate when they are turned

the actuating shaft 20 perform a movement between the displacement plane and the closing plane, as is shown in solid or dash-dotted lines in FIG. 5.

Through a suitable design of the control curve 27b, in the exemplary embodiment according to FIG. 5, in addition to the conversion movement between the closing plane and the shifting plane, which takes place in a horizontal direction, a targeted raising and lowering of the supporting profile 9 can take place, so that the wall parts 5 by means of their supporting profile 9 not only in the required Lowered onto the flanged wheels 26 or 10 can be lifted from these flanged wheels 26, but can also be moved into a predeterminable closed position, which is not only located to the side of the shifting plane, but opposite the shifted position, for example to achieve a special sealing intervention can be raised, as shown in FIG. 5.

Regardless of the embodiment of the bearing elements, each wall part 5 is provided on its upper edge with a guide profile 10, the cross section of which is shown in FIG. 6. 20th

This guide profile 10 comprises a guide track 10a with a C-shaped cross section and a guide rail 10b with a hook-shaped cross section. With this guide rail 10b, a wall part 5 in the shift position engages in the guide track 10a of the wall parts 5 in the closed position, so that each wall part 5 in the shifting plane is guided on its upper edge to the wall parts 5 in the closing plane.

Push forks 29 act on the guide rail 10b and are actuated by a shaft 31 by means of a lever 30 in order to transfer the upper side of the wall parts 5 between the closing plane and the displacement plane. 7, the shaft 31 is connected via a linkage 32a, 32b to the hand lever 22, which causes the actuating shaft 20 belonging to a wall part 5 to rotate on the lower long beam 7. In this way, the respective sliding forks 29 assigned to a wall part 5 in the closed position are actuated jointly and simultaneously with the slides 18, or the transfer device 24 or with the cam levers 27 by a single hand lever 22.
