[0030] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0031] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0032] As mentioned in the above background technology, the present application realizes that there are some shortcomings in the installation method of multiple components in the side area of ​​the locomotive in the current technology. Specifically, the side beam is directly welded to the chassis, with various forms and quantities, and it is necessary to use a positioning tool to limit the position. It is almost impossible to adjust after welding, and the fault tolerance rate is low. The welded side beam structure has a single function. The installation of components such as side decorative panels, pipelines, wire ducts, corridor floors, etc. requires the installation of additional mounting structures, and then the mounting structures are welded to the side beams. The various mounting structures are intertwined, and the installation error rate is high, and the production efficiency is low. The mounting structures of multiple components all need to be welded to the side beams. The errors of each component itself plus the welding errors may cause interference between the components during installation, and even require rework and repositioning welding. The number of welding mounting seats for each component is large, the relative position size requirements are high, the number of positioning tools is large, and the size positioning is not easy to ensure. The handrails, side decorative panels, pipelines, wire ducts, corridor floors and other components are installed separately on the main assembly pipeline. The main assembly pipeline of locomotive production occupies too much, which is not conducive to reducing the locomotive production cycle. The simultaneous cross-installation of multiple professions at the same assembly station can easily lead to confusion in the assembly sequence, resulting in errors or even rework. Pipes and cable ducts are installed on the upper side of the side beam, and the space utilization rate in the height direction is low. In order to solve the problems existing in the prior art, the present application proposes one or more embodiments to be described below.

[0033] refer to Figure 2The present invention proposes a support unit 100 for a locomotive side suspension module 200, comprising: a plurality of brackets 110 arranged at intervals in the longitudinal direction; a plurality of connecting beams 120 arranged at intervals in the longitudinal direction, each connecting beam 120 being detachably connected between two adjacent brackets 110. The plurality of brackets 110 and the plurality of connecting beams 120 are combined to obtain a frame structure extending in the longitudinal direction, which is used to carry a variety of components in the side areas of various locomotives. The support unit 100 itself constitutes a modular structure that can be independently produced and assembled. The support unit 100 is composed of the brackets 110 and the connecting beams 120 as basic components, and has a high reuse rate. The length of the support unit 100 in the longitudinal direction can be adjusted by adjusting the number of the brackets 110 and the connecting beams 120 to meet the individual needs of different lengths of vehicle models. The support unit 100 defines a longitudinal direction, a transverse direction and a vertical direction, which correspond to the length direction, the width direction and the height direction respectively. The support unit 100 is respectively connected to the locomotive underframe and suspended on opposite sides in the transverse direction. The side of the support unit 100 joined to the vehicle body underframe is referred to as the lateral inner side, and the side of the support unit 100 away from the vehicle body underframe is referred to as the lateral outer side.

[0034] The bracket 110 and the connecting beam 120 can be connected in a detachable manner so that the number can be increased or decreased by disassembly and assembly, thereby adjusting the longitudinal length of the supporting unit 100. Figure 5 A connecting beam mounting seat 115 is provided on both longitudinal sides of the bracket 110. The connecting beam mounting seat 115 can support the longitudinal side areas of the connecting beam 120 and is provided with a mounting hole. The mounting hole cooperates with the fastener to realize the detachable connection between the bracket 110 and the connecting beam 120.

[0035] Figure 3 FIG. 1 shows a schematic diagram of functional divisions of a support unit 100 according to an embodiment of the present invention. Figure 3As shown, the bracket 110 forms a mounting area a for the support unit 100 itself and the vehicle body chassis on the lateral inner side, and the mounting area has a support unit mounting member for mounting the support unit 100 to the locomotive chassis 10. The bracket 110 forms a handrail mounting area d on the lateral outer side, and the mounting area has a handrail mounting member. The connecting beam 120 forms a side trim mounting area e on the lateral outer side, and the mounting area has a side trim mounting member. The upper side of the connecting beam 120 forms a corridor floor mounting area c, and the corridor floor mounting member. The interior of the support unit 100 forms a brake pipeline and electrical line installation area b, and the installation area has a storage space for accommodating pipelines and lines. The interior of the support unit 100 also forms an expansion equipment installation area g, and the installation area has an additional storage space spaced laterally from the storage space. The lower part of the bracket 110 also forms a charger socket installation area f, and the installation area has a charger socket mounting member. The support unit 100 also has an operation area h between the connecting beam 120 and the chassis, which reserves the necessary operation space for installing the locomotive side suspension module 200. Each functional area of ​​the support unit 100 performs its own functions, and the layout is reasonable, which cleverly and fully utilizes the areas and spaces in all directions of the support unit 100.

[0036] In an embodiment of the present invention, the support unit 100 integrates a variety of mounting structures such as a support unit mounting part, a handrail mounting part, a side trim mounting part, a corridor floor mounting part, and a pipe and line accommodating space, so that a variety of components such as a handrail, a side trim, a corridor floor, and pipes and lines can be integrated into the support unit 100 to form an integral side suspension module, and then the side suspension module is installed to the locomotive chassis through the support unit mounting part. In this way, the side suspension module can be assembled separately and carried out in parallel with the production of other structures of the vehicle body, so as to achieve the purpose of synchronous production in multiple scenarios, which is conducive to shortening the production cycle. At the same time, the layout of the various mounting structures is reasonable, so that the various components can be installed in an orderly manner without interfering with each other.

[0037] refer to Figure 2 and Figure 3 In some embodiments, the bracket 110 includes a U-shaped portion with an upper opening, and the connecting beam 120 is connected to the upper portion of the bracket 110 and connects the two opposite lateral sides of the U-shaped portion. The U-shaped portions of multiple brackets 110 and the multiple connecting beams 120 jointly define a storage space. The storage space includes the storage space formed by the U-shaped portion and the space below the connecting beam 120, and the storage space extends in the longitudinal direction. Due to the constraints of the installation position of the pipeline and the line, the bracket 110 itself has a U-shaped structure, resulting in a large bending moment in the bearing area of ​​the bracket 110. However, after the upper connecting beam 120 is laterally connected on both sides of the U-shaped portion, the force condition of the bearing area of ​​the bracket 110 is qualitatively improved. Reference Figure 5In some embodiments, a wire trough mounting seat 113 is provided on the side wall of the U-shaped portion, and a pipeline slide rail 114 is provided on the bottom wall of the U-shaped portion to realize layered arrangement of lines and pipelines.

[0038] In some embodiments, a receiving hole is formed on the bracket 110, and the receiving holes of the plurality of brackets 110 define the additional receiving space described above. In some embodiments, the bracket 110 has a protruding portion protruding laterally inward relative to the connecting beam 120, and the protruding portions of the plurality of brackets 110 define the operating space described above for installing the side suspension module.

[0039] refer to Figures 3 to 5 In some embodiments, the bracket 110 has two support unit mounting members respectively arranged at the upper and lower parts thereof, and the mounting directions of the two support unit mounting members are respectively arranged in the horizontal direction and the vertical direction. The support unit mounting member can be a support unit mounting hole 118, which cooperates with the fastener 12 to mount the bracket 110 to the locomotive chassis 10. The hole depth directions of the two support unit mounting holes 118 are respectively arranged in the horizontal direction and the vertical direction, and accordingly, the extension directions of the two fasteners 12 are respectively arranged in the horizontal direction and the vertical direction. The fastener 12 can be a T-bolt, and the locomotive chassis 10 is provided with a slideway 14 that cooperates with it.

[0040] The support unit 100 is mainly subjected to the vertical load F1 formed by its own weight and the weight of various components installed on it. Since the support unit 100 and the base frame 10 are cantilever structures, a clockwise bending moment is formed under the combined action of the load F1 and the lever arm. The slideway 14 is welded to both sides of the base frame in advance as a medium for load transmission between the side suspension module and the base frame, and has both vertical and horizontal load-bearing directions. The T-bolts and the slideway 14 cooperate with each other to transfer the vertical force and bending moment brought by the cantilever structure through the lateral reaction force F 2x and vertical reaction force F 2y The support unit 100 is transferred to the underframe 10. Therefore, the present invention can improve the connection strength between the support unit 100 and the underframe of the locomotive by providing two support unit mounting members which are respectively arranged in the horizontal direction and the vertical direction.

[0041] The two support unit mounting parts are respectively arranged at the upper and lower parts of the bracket 110 to ensure that the distance between the two is as large as possible, and they are installed as much as possible corresponding to the upper and lower planes of the chassis, so that the cantilever structure of the side suspension module has the greatest possible rigidity. The positive tension received by the upper fastener is set in the horizontal direction, and the positive tension received by the lower fastener is set in the vertical direction. Such an arrangement fully utilizes the positive tension that the two fasteners can bear. In some embodiments, the lateral inner side of the bracket 110 forms a fitting surface that can fit with the locomotive chassis 10, and the fitting surface is located between the two support unit mounting parts. Therefore, the side of the support unit 100 close to the chassis 10 fits with the vertical surface of the chassis 10, which can maximize the elimination of the torsional moment of the cantilever structure on the fastener 12, thereby achieving a stable connection between the entire side suspension module and the chassis 10.

[0042] refer to Figure 5 In some embodiments, the handrail mounting member includes a receiving slot 116 (e.g., a C-shaped slot) for receiving the handrail and a handrail mounting plate 117 having a mounting hole, wherein the receiving slot 116 is arranged vertically and has a side opening on the outer side in the transverse direction, and the handrail mounting plate 117 is fixed in the side opening. The lower area of ​​the handrail can be inserted into the receiving slot 116 and the handrail can be fixed to the bracket 110 by fasteners cooperating with the mounting holes of the handrail mounting plate 117.

[0043] In some embodiments, the handrail mounting member includes a plurality of handrail mounting plates 117, and the plurality of handrail mounting plates 117 are fixed in the side opening at intervals, and the intervals between adjacent handrail mounting plates 117 allow for the insertion of adjustment gaskets. In this way, adjustment gaskets can be conveniently arranged between the handrail and each handrail mounting plate 117, so that the verticality of the handrail can be adjusted on the one hand, and the lateral position of the handrail can be adjusted on the other hand, so as to ensure that the plurality of handrails are neatly arranged in the same straight line.

[0044] refer to Figure 5 In some embodiments, the main body of the bracket 110 is formed by intermittent welding of a vertical plate 111 and two enclosure plates 112, and weld sealant is applied to the welds to avoid excessive structural welding deformation due to long welds and to avoid rust at the weld positions.

[0045] refer to Figure 6 and Figure 7 In some embodiments, the connecting beam 120 includes a top surface, a side surface extending downward from the lateral outer side of the top surface, and a flange extending inward from the side surface; the side trim panel mounting member includes a plurality of side trim panel mounting holes formed on the flange and arranged longitudinally, and the plurality of side trim panel mounting holes may include a plurality of oblong holes and a plurality of round holes arranged alternately; the corridor floor mounting member includes a plurality of fastener mounting seats arranged on the top surface.

[0046] The main body of the connecting beam 120 can be welded by a profiled part 121 and a rib plate 122 to ensure structural strength. The selection of the profiled part 121 can greatly reduce the welds caused by the splicing of the plates, effectively improve the manufacturing accuracy of the connecting beam 120, simplify the manufacturing process, and improve product quality. The circular holes and the oblong holes on the bottom surface of the profiled part 121 are arranged alternately in rows, integrating the installation interface between the connecting beam 120 and the bracket 110, the side decorative plate installation interface, and the charger installation interface, which can be flexibly adapted to the installation of different structures. The circular holes and the oblong holes cooperate with each other, the oblong holes can adapt to the longitudinal adjustment amount of different installation structures, and the circular holes can ensure the longitudinal positioning of the installation structure. The pre-welded fastener mounting seat (such as a screw seat) 123 under the connecting beam 120 is used for corridor floor installation. The top surface and the side surface of the profiled part 121 are hollowed out to form a plurality of hollow parts 124, which can achieve the effect of weight reduction on the one hand, and facilitate the installation of various components on the support unit 100 on the other hand.

[0047] Figure 8 FIG. 2 is a schematic diagram showing a locomotive side suspension module 200 formed by installing various components on a support unit 100 according to an embodiment of the present invention. Figure 8 As shown, the locomotive side suspension module 200 includes a support unit 100 and a handrail 210, a side trim 220, a corridor floor 230, a line 240, a pipeline 250 and a charger socket 260 installed in different functional areas of the support unit 100.

[0048] In summary, the present invention replaces the traditional locomotive welded side beam form with a mounted support unit. The support structure integrates the connection beam mounting seat, the wire trough mounting seat, the brake pipe slide rail, the handrail mounting seat, the support unit mounting piece, the corridor floor mounting piece, the side trim mounting piece and other multi-functions in one, which can realize the modular integrated installation of various components of the side suspension module, meet the personalized installation requirements of various components of the side suspension module, and improve the space utilization of the support unit. While meeting its own structural strength, the support unit highly matches the installation of other components under the side suspension module and can achieve lightweight.

[0049] The side suspension module integrates the structure and equipment of the side beam area on both sides of the locomotive, so that the load-bearing structure, brake lines, electrical lines, corridor floors, handrails, side trims and other components in this area form independent modules. The side suspension module takes the main support unit as the core and link. By integrating other structures and components in the area and hanging them sideways on the main load-bearing structure of the car body, the modular disassembly and assembly of this area of ​​the locomotive is realized, and the assembly of components in different scenes is realized, which can reduce the workload of the same workstation, realize the ground assembly of independent module accessories, and shorten the main pipeline working hours. Ultimately, it is possible to simplify the manufacturing process, improve product quality, improve production efficiency, reduce production costs and maintenance costs, and increase product service life. The present invention can be used to produce shunting locomotives that use new energy as power, are modularly intelligently manufactured, have a high degree of automation, and have low manufacturing and maintenance costs.
