Compressed-air rack for an electric locomotive

Abstract

A compressed-air rack for an electric locomotive includes an electric assembly that is inserted between sheet metal walls of the compressed-air rack and is provided with electric modules which are accessible from the front. In order to be able to produce the electric assembly in a comparatively inexpensive manner and to mount the same with relative ease in the compressed air rack, the electric assembly includes a frame that has no rear wall and has open sides and reinforcing transverse members similar to a skeleton, and electric modules are mounted on the transverse members.

Claims

1. A compressed-air rack of an electric locomotive, the compressed-air rack comprising: sheet metal rack walls; and an electric assembly inserted between said sheet metal rack walls; said electric assembly having a frame with a front, a rear, no rear wall, open sides and reinforcing transverse members in a skeleton structure, said transverse members resting on said front of said frame and said transverse member having a rear; said electric assembly having electric modules accessible from said front and electric modules attached to said transverse members; U-shaped mounting plates supported on said rear of said transverse members; and a longitudinal member connected to said U-shaped mounting plates and connected above and below to said rear of said frame.

2. The compressed-air rack according to claim 1, wherein said frame is a single-piece, flexible sheet metal part.

3. The compressed-air rack according to claim 1, wherein said frame has side walls with recesses formed therein for receiving said electric modules.

4. The compressed-air rack according to claim 1, which further comprises sealing side plates attached to said front of said frame.

5. The compressed-air rack according to claim 4, which further comprises stops attached to one of said side plates, and a front door supported by said stops.

6. The compressed-air rack according to claim 1, which further comprises a reinforcing cover fitted to said frame.

7. The compressed-air rack according to claim 1, wherein said frame is screwed into the compressed-air rack.

8. The compressed-air rack according to claim 1, wherein said frame of said electric assembly is inserted directly between said sheet metal rack walls to form a module being enclosed on all sides.

Description

(1) An arrangement which can be compared with a conventional electronics cabinet is thus formed without additional side walls and a rear wall.

(2) To further explain the invention

(3) FIG. 1 shows an oblique view laterally from the front of an exemplary embodiment of a frame of the electric assembly of a compressed-air rack with fixed side walls

(4) FIG. 2 shows a rear view of the same exemplary embodiment according to FIG. 1 obliquely from the rear,

(5) FIG. 3 shows the same exemplary embodiment of a bogie truck with electric modules already mounted,

(6) FIG. 4 shows the same exemplary embodiment upon introduction into a compressed-air rack with a fixed cover and

(7) FIG. 5 shows the compressed-air rack with an introduced electric assembly.

DESCRIPTION OF THE INVENTION

(8) FIGS. 1 and 2 show a frame 1 of an electric assembly, otherwise not shown in further detail here, of a compressed-air rack which is likewise not reproduced here. The frame 1 is embodied similar to a skeleton, by it having neither a front side nor a rear side, but only open side walls 2 and 3, which are connected to one another on the topside of the frame 1 by means of upper connecting sheets 4 and 5 and below by means of a base plate 6. The frame 1 further comprises a transverse member 7 and a further transverse member 8, which connect the side walls 2 and 3 to one another in a reinforcing manner on the front side of the frame 1 in each case.

(9) As can be seen in particular in FIG. 2, U-shaped mounting plates 9 and 10 are fastened to the transverse member 7 and to the further transverse member 8. A longitudinal member 11 is connected to these mounting plates 9 and 10, which, at its upper end 12, is connected to the upper connecting sheet 4 and at its lower end 13 in the region of the base plate 6 is connected to the frame 1.

(10) As shown above all in FIG. 1, a side plate 14 and a further side plate 15 are attached to the front side of the frame 1, said side plates being connected in a sealing manner (not shown) to the side walls 2 and 3 of the frame 1.

(11) FIG. 3 shows the almost completely finished electric assembly 20 with electric modules 21, such as are also used in cabinet designs of electric assemblies. It is also apparent here that these electric modules are not only fastened to the transverse members 7 and 8 but are instead also introduced into recesses 22 and 23 in the form of further electric modules 24 and 25. FIG. 3 further shows that additional electric modules 26 are accommodated in a lower region of the electric assembly 20. It is likewise apparent that wires are routed from the electric assembly 20 to external connection elements 27.

(12) FIG. 4 shows a compressed-air rack 30, such as can be used within the scope of the invention. It is apparent that the compressed-air rack has sheet metal walls 31 and 32, which form a receiving space for the electric assembly 20. It is indicated in the state shown, how, precisely, the electric assembly 20 is inserted in the direction of the arrow 33 between the sheet metal walls 31 and 32 into the compressed-air rack 30, wherein an additional reinforcement and termination of the electric assembly 20 is effected by means of a cover 34 in the fixed state.

(13) FIG. 5 finally shows the electric assembly 20 in a state integrated into the compressed-air rack with a door 40, which abuts a side plate 15 by means of stops 41. The cover 34 is in the fixed state here.
