[Prior art] In the ground, when the rail vehicle is running, the bending load caused by the load is first received or transmitted by the main cross frame. The rail vehicle of Weizhi Technology towel is usually provided with two rotating brackets, which are respectively located in the longitudinal end area of the vehicle. However, a main cross frame is provided above each rotating bracket to guide the vehicle's load. To each rotating stand. Therefore, the main cross frame must have a corresponding f-curve strength. In order to increase the strength of the f-curve, it can be achieved by increasing the height of the profile of the main cross frame. This degree needs to summarize the entire height between the top angle of the rotating bracket and the ground plane of the vehicle to achieve the maximum strength. A horizontal bracket may be set beside the main horizontal frame to support the ground. Regarding floor profiles, it is known to have a _ main age structure. The first line is to consider that there is a large distance between the top angle of the rotating bracket and the ground plane of the motor vehicle, and there is a main horizontal frame above each rotating bracket below the ground profile, and the ground profile It is set on one or a plurality of upper narrow plates of the main cross frame, and it is arranged on the entire length of the motor vehicle without interruption. Another structure is used in a large distance between the top angle of the rotating bracket and the ground plane of the motor vehicle to provide the required profile height of the main cross frame. In addition, on the main cross frame, the floor profile is cut and welded to the longitudinal side and the side of the narrow plate above the top of the connection plate. The upper narrow plate of the main cross frame replaces the top 572839 side of the floor profile forming the ground in the area between the cut ground profiles. The purpose of this design is that the main pine frame has a sufficiently high profile at a small distance between the top angle of the rotating bracket and the ground plane of the motor vehicle. One of the advantages of floor profiles running through the entire length is that the floor is manufactured fully automatically. Compared with the non-vertical full-length floor profile, the design of the vertical full-length design can greatly improve the welding of the floor profile and the long support. Because the floor profile and the two long brackets run through the length of the temple, the machine can be used. Carry out welding work. If the main horizontal frame is inserted into the ground, the welding seam on the bottom side of the ground can only be mixed. In the main horizontal thin area, manual square wire is required for work and work, which is greatly increasing the production cost. Another advantage of using a floor profile that runs through the entire length is that a very flat floor can be obtained in a fully automatic manner. However, the bending force of the floor profile across the entire length is reduced, and then it acts on the main crossbar, because the load generated will be absorbed by the floor profile. Therefore, on a non-vertical full-length floor profile, the main cross frame will have a higher load than the vertical-length floor profile. Therefore, the use of a ground profile that runs through the entire length of a rail vehicle has technical and economic advantages. In rail vehicles with a very small distance between the top angle of the rotating bracket and the ground plane of the vehicle, especially in the subway, the setting of the ground profile that runs through the entire length, and at the same time when the necessary bending strength of the main crossbar is reached This is indeed an unsolved technical issue. [Summary of the Invention] The main object of the present invention is to invent a railroad vehicle that has a long full-length floor profile even on a rail vehicle with a very small distance between the top angle of the rotating bracket and the ground plane of the vehicle, and 6 572839 and The main cross frame can have the required bending strength. The above purpose can be at least partially guided to the bottom side of the floor profile by the connection plate of the narrow plate under the main difficulty, and connected to it, but the upper narrow plate of the main cross frame is respectively related to the bottom profile of the floor profile. Combining to achieve. Through the structure of the main cross frame above the ground profile—or a plurality of upper narrow plates and the connection plate and the lower narrow plate below the ground profile, the part of the ground profile is located in the area corresponding to the main cross frame. The profile of the profile is increased, the required bending strength is achieved, and there is no need to cut the ground profile on the main crossbar. When connecting the connection plate to the ground, it is convenient to weld the square wires. With the connecting plate 6 provided with a widened portion 7 on the contact surface with the bottom side 3a of the ground profile 3, this design can simplify the work when the connecting plate is welded to the bottom side of the ground profile. In addition, another advantage of the present invention is that when one or more upper narrow plates are connected to the main cross frame, at least one of the upper narrow plates is welded to the top side of the floor profile. Another advantage of the present invention is that, in order to make a better connection with the top side of the surface profile, the main cross frame is provided with two upper narrow plates, which are welded to the top side of the ground profile within a preset clearance. With this design, the ratio of the area of the narrow plate to the area of the welded seam is reduced when compared with the vertical upper narrow plate, so the direct friction with the floor profile is greatly improved. Because a pneumatic spring is provided below the lower narrow plate of the main cross frame, its diameter is equal to the width of the main cross frame, and the f-curved load of the lower f plate is formed by the spring pressure. Therefore, in order to partially increase the lower narrow plate, For the strength of the flat plate, the present invention is arranged on the τ side between the upper narrow plates—connecting plates. 7 572839 In addition, a preferred embodiment of the floor profile is that in order to further increase the bending strength in the range of the main cross frame, the floor profile is made into a triangular cross section. In order to reduce the weight of the main crossbar, pure ㈣ can be used as the material of the main crossbar. In order to reduce the weight of the floor profile, the material can be used as the material of the floor profile. Through the integral forming of the connecting plate and the lower narrow plate, the purpose of reducing production costs and facilitating production can be achieved. In terms of reducing production costs, the lightweight main crossbar can be completed by means of high quality casting. In order to achieve light weight, the main cross frame can be made of large aluminum material. In order to further understand the structural features, technical contents and functions of the present invention, please refer to the following drawings of the Lions of the present invention, but the series are for reference and explanation, and are not intended to limit the present invention. . [Embodiment] As shown in the figure 'and referring to Figs. 2 and 3, the ground profile 3 is fixed on the main cross frame 2 of the rail vehicle 1, and the shed of the ground profile 3 forms a floor. As shown in FIG. 2 and FIG. 3, the narrow plates 5 a and 5 b above the main cross frame 2 are provided directly above the floor profile 3 and are welded to the top side of the floor profile 3. Welding of the upper narrow plates 5a, 5b is easier because they are provided on the floor profile 3 running through the entire length. Therefore, the sides of the upper narrow plates 5a, 5b must be welded to the top weave of the floor profile 3. Since the welds are straight-lined, the work has to be performed by machines. With the conventional technology, the present invention can save the work of the material consumption # required for the welding of the long brakes on the ground. In order to achieve the required f-curve strength ', the floor profile 3 is provided with a diagonal wooden monument 9. Below the floor profile 3 ', from the lower narrow plate of the main prism 2 to the bottom side 3 of the floor profile 3, the connection plate is known, b, c, and 572839 is welded to the bottom side 3a of the floor profile 3. The welding work of the bottom side 3a and the connection plate 6 is also performed by a machine because of the widened portion 7 at the bottom end of the connection plate. A rotating bracket (not shown) is provided under the main cross frame 2, and the load of the carriage is guided into the rotating frame via the main cross frame 2. Through its longitudinal side ends, the main cross frame 2 and the long bracket 8 (vertically arranged on the entire length of the rail vehicle) must be combined into a lion structure, and the _long support system is connected to the lower end of the side rail of the rail vehicle and the side The wall 10 extends into the upper narrow plate 53, _ of the long bracket 8. In addition, the upper ends of the side walls 10 are connected to each other into a cap shape. g In this embodiment, each upper cross frame 2 is provided with two upper narrow plates 5a, 5b. According to this design, as mentioned above, it can be connected between the upper lose 5a, 5b and the ground bet 3-because the ratio of the area of the upper narrow plates 5a, 5b to the area of the welding seam 13 is difficult, As shown in FIG. 3, the improvement can be achieved only by an extremely wide upper narrow plate 5. Because in this embodiment, a pneumatic elastic bullet (not shown) is provided under the lower narrow plate, which can apply force to put the lower narrow plate under a -bending load. Therefore, the upper and lower narrow plates 5 & A connection plate 6b is additionally provided within the range between 5b to partially improve the rigidity of the flat plate. The connection plate is connected to the lower narrow secret eye connection, but is not welded to the bottom side 2a of the main cross frame 2, because it only provides the support function and only receives pressure. Within the range of the floor profile 3, the diagonal wooden brick 9 conducts the load 'between the upper narrow plate 5 and the lower narrow pepper', especially through the pushing stress generated by the lateral force. Therefore, the diagonal type wooden monument 9 has the function of the connecting plate 6 of the main cross frame 2 within the range of the floor profile 3. As shown in FIG. 3, the present invention can also provide a full-length ground profile 3 on a very limited space between the top angle of the rotating bracket and the ground level of the rail vehicle 9 572839, because the position of the ground profile 3 is passed through the ' In the range between the lower narrow plate 4 and the upper narrow plates 5 & 5b of the main cross frame 2, the height of the profile can be increased to h '. Therefore, the required bending rigidity can be achieved, and No need for extra space. The connecting plate 6a '& separated-welding seams of the peripheral equipment 丨 the handle is connected to the bottom side of the ground 3, and at the same time, the connecting plates 6a, b, c and the lower narrow plate 4 can be easily and cheaply constructed. to make. Generally, a horizontal support (not shown) for supporting the ground is provided beside the main horizontal frame 2. It does not need to bear a large load. Only f is higher than the main age 2 and can be used for riding. Can be set under ground orchid 3. The original domain of the present invention is made based on the consideration of the county. 0 [Schematic description] Figure 1 is a cross-sectional view of the upper part of a rail vehicle; A three-dimensional sectional view of the vehicle surface; FIG. 3 is a sectional view taken along the line III-III of FIG.
