A railway vehicle 100 according to an embodiment of the invention is described below with reference to fig. 1-27. The rail vehicle 100 may be applied to a rail vehicle such as a straddle monorail train (not shown). In the following description of the present application, an example in which the rail vehicle 100 is applied to a rail vehicle such as a straddle monorail car will be described. Of course, it will be understood by those skilled in the art that the rail vehicle 100 may also be applied to other types of rail vehicles and is not limited to straddle monorail cars.

As shown in fig. 1 to 27, a railway vehicle 100 according to an embodiment of the first aspect of the present invention includes a floor panel 1 and a wheel package 3.

Specifically, the floor panel 1 is provided with an opening 11. Two wheel assembly and disassembly floor blocks 5 are arranged in the opening part 11, a sub opening part is defined between the two wheel assembly and disassembly floor blocks 5, a wheel 2 is arranged at the sub opening part, one part of the wheel 2 penetrates through the sub opening part and protrudes out of the upper surface of the floor 1, and the two wheel assembly and disassembly floor blocks 5 are respectively positioned at two sides of the wheel 2 in the front-back direction of the rail vehicle 100. The two wheel dismounting floor blocks 5 are detachably connected with the floor 1. The wheel package 3 covers the upper part of the wheel 2, and the wheel package 3 is connected with two wheel dismounting floor blocks 5.

For example, referring to fig. 1 to 3 and 5 in combination with fig. 16, the floor panel 1 extends in a horizontal direction, the opening 11 can penetrate the floor panel 1 in a vertical direction, two floor panels 5 for wheel attachment and detachment are provided at intervals on both sides of the opening 11 in a longitudinal direction of the floor panel 1, in this case, a width of the sub opening in the longitudinal direction of the floor panel 1 is smaller than a width of the opening 11 in the longitudinal direction of the floor panel 1, the wheel 2 is inserted into the sub opening, an upper portion of the wheel 2 is located above the floor panel 1, and a lower portion of the wheel 2 is located below the floor panel 1. So, through setting up foretell two wheel dismouting floor blocks 5, the area of whole floor 1 has been increased, and, through fixing wheel package 3 on two wheel dismouting floor blocks 5, the volume of wheel package 3 has been reduced, reduce the weight of wheel package and shared space, realize the installation of little wheel package, passenger space has been increased relatively, when rail vehicle 100 is applied to rail vehicle for example when striding a formula single track train, same passenger number, whole car length can be reduced to this kind of scheme, lighten whole car weight, and then improve the performance of whole car. In addition, the distance between the wheel 2 and the two wheel assembling and disassembling floor blocks 5 is short, the wheel space (namely the sub opening part) reserved in the body of the railway vehicle such as a straddle type monorail train can be reduced, the noise in the vehicle can be further reduced, and the riding comfort is improved. The wheels 2 may be running wheels of a rail vehicle, such as a straddle monorail, among others.

When the wheel 2 needs to be disassembled, the wheel package 3 can be disassembled firstly, then the two wheel disassembly floor blocks 5 are disassembled, and the wheel 2 is finally disassembled after enough disassembly space of the wheel 2 is reserved; on the contrary, when the wheel 2 is installed, the wheel 2 can be installed firstly, then the two wheel dismounting floor blocks 5 are installed, and finally the wheel package 3 is installed. Therefore, the wheel 2 can be assembled and disassembled in the vehicle. Compare with the mode of traditional car outer wheel of trading, easy dismounting, it is efficient, and labour saving and time saving.

According to the rail vehicle 100 of the embodiment of the invention, the two detachable wheel dismounting floor blocks 5 which are positioned at two radial sides of the wheel 2 are arranged, a part of the wheel 2 can penetrate through the sub-opening part between the two wheel dismounting floor blocks 5, and the wheel packet 3 is connected with the two wheel dismounting floor blocks 5, so that the area of the whole floor 1 is increased, the occupied space of the wheel packet can be relatively reduced, and the weight of the wheel packet 3 is reduced. When the rail vehicle 100 is applied to a rail vehicle such as a straddle-type monorail train, the weight of the rail vehicle such as a straddle-type monorail train is reduced while the vehicle wheels 2 are removed in the vehicle, the performance of the rail vehicle such as a straddle-type monorail train is improved, and the wheel space reserved by the vehicle body is reduced, so that the noise in the vehicle can be reduced, and the riding comfort of passengers is improved.

According to some embodiments of the invention, as shown in fig. 10 and 11, the central axis of the wheel 2 is lower than the upper surface of the floor panel 1. The centre axis of the wheel 2 is now located below the level of the floor 1. The size of the portion of the wheel 2 located above the floor 1 is smaller than the size of the portion thereof located below the floor 1. Thus, the part of the wheels 2, such as the running wheels, which protrudes out of the floor 1 is small, a certain low floor is realized, the proportion of the protruding part of the running wheels occupying the space of passengers is reduced, and the riding comfort is improved. Referring to fig. 8, the distance between the two wheel mounting/dismounting floor boards 5 in the longitudinal direction of the floor 1 is smaller than the diameter of the wheel 2. So set up, can further increase the area on whole floor 1, reduce the size that wheel 2 protrudes floor 1 for the occupation space of wheel package 3 can further reduce, and the weight of wheel package 3 can further alleviate, and the wheel space that the automobile body was reserved can further reduce, and the noise in the car can further reduce, and whole rail vehicle for example striding a formula monorail train's structure can be compacter, and rail vehicle for example striding a formula monorail train's performance can further promote.

Alternatively, the maximum width of the opening portion 11 in the longitudinal direction of the floor panel 1 is larger than the diameter of the wheel 2. Therefore, after the two wheels are disassembled and the floor blocks 5 are disassembled, the wheels 2 can be further conveniently disassembled in the vehicle. Alternatively, the longitudinal width of the opening 11 is at least 100mm larger than the diameter of the wheel 2, and since the weight of the wheel 2 is about 200kg, there is a shaking amount of the wheel 2 when the wheel 2 is disassembled, so as to better facilitate the disassembly of the wheel 2.

According to some embodiments of the present invention, as shown in fig. 10 to 11, the edge of the floor 1 at the opening 11 is provided with a step structure 13, and the side of each of the wheel mounting/dismounting floor boards 5 away from the wheel 2 is provided above the step structure 13 and the upper surface of the service floor board 4 is flush with the upper surface of the floor 1. For example, the step structure 13 may include a first upper surface 131 and a second upper surface 132 which are not located in the same plane, the first upper surface 131 is higher than the second upper surface 132, and the first upper surface 131 is located on the side of the second upper surface 132 far from the wheel 2, when the wheel mounting plate 5 is mounted, a portion of the wheel mounting plate 5 extends above the second upper surface 132 and fits on the second upper surface 132, and the upper surface of the wheel mounting plate 5 is flush with the first upper surface 131. Therefore, the whole floor 1 can be effectively ensured to be positioned in the same plane.

According to a further embodiment of the present invention, referring to fig. 10 and 11, a sealing member 124 is provided between each of the wheel mounting and dismounting floor boards 5 and the floor 1. For example, in the example of fig. 10 and 11, the side of each wheel attachment/detachment floor panel 5 remote from the wheel 2 extends above the second upper surface 132 of the floor 1 as described above, and the sealing member 124 is provided between the lower surface of the side of each wheel attachment/detachment floor panel 5 remote from the wheel 2 and the second upper surface 132 of the floor 1. So set up, above-mentioned one side of keeping away from wheel 2 of every wheel dismouting floor block 5 can the overlap joint on floor 1, can reduce the noise transmission, and made things convenient for the installation of sealing member 124, because the sealing member 124 can seal up the clearance between wheel dismouting floor block 5 and the floor 1 to can effectively completely cut off with rail vehicle for example stride the noise of the lower automobile body of a formula monorail train.

Optionally, the seal 124 is a sealing rubber. For example, the seal 124 may be a sealing rubber pad.

Here, it should be noted that the direction "in" is understood to be a direction toward the center of the interior of the wheel package seat assembly 7, and the opposite direction is defined as "out", i.e., a direction away from the center of the interior of the wheel package seat assembly 7. With the arrangement, the bolt structure 8 can be well hidden inside the wheel package seat assembly 7, and the structural compactness of the whole railway vehicle 100 is ensured. In the attaching/detaching operation, the seal plate 24 in the opening 11 can be opened to tighten or loosen the bolt structure 8.

Specifically, as shown in fig. 21-25, at least one fastener 341 may be fixedly attached to the sealing plate 34, the fastener 341 includes a shaft 3411 and an end 3412, one end of the shaft 3411 is connected to the sealing plate 34, the end 3412 is connected to the other end of the shaft 3411, a maximum dimension of the end 3412 in a cross section of the shaft 3411 is larger than a maximum dimension of the shaft 3411 in a cross section of the shaft 3411, and the end 3412 may be formed in an elongated shape. At least one mounting plate 331 is disposed at a position corresponding to the wheel package mounting opening 33 of the wheel package seat assembly 7, a locking structure 332 is disposed on the mounting plate 331, and a long hole 3321 adapted to the shape of the end 3412 is formed in the locking structure 332. When the locking structure is installed, the end 3412 of the fastening member 341 on the closing plate 34 passes through the mounting plate 331 and the elongated hole 3321 on the locking structure 332 and then is rotated by a certain angle, and at this time, the end 3412 is misaligned with the elongated hole 3321 on the locking structure 332, so that the closing plate 34 can be securely installed at the wheel package installation opening 33. Removal is accomplished by simply rotating fastener 341 so that end 3412 is aligned with elongated opening 3321 of locking structure 332 and then removing closure plate 34 outwardly, whereupon fastener 341 is withdrawn from elongated opening 3321 of locking structure 332 and mounting plate 331.

Of course, the bolt structure 8 may also be located outside the wheel package seat assembly 7, a groove with an open top is formed on the floor 1, the bolt structure 8 is located in the groove, and a detachable cover plate (not shown) is arranged at the top of the groove. Therefore, the bolt structure 8 is arranged on the outer side of the wheel package seat assembly 7, assembly and disassembly are facilitated, the bolt structure 8 can be well hidden under the cover plate due to the cover plate, and the attractiveness of the whole railway vehicle 100 can be well guaranteed.

When the assembly or disassembly is needed, the wheel package seat assembly 7 is disassembled integrally. Specifically, the wheel package seat assembly 7 is fixed to the floor 1 by the bolt 83 in the C-shaped groove 811 of the first connecting member 81. When it is necessary to detach the wheel package seat assembly 7, the trim cover plate 24 or the cover plate is removed, and then the bolts 83, such as fastening bolts, are loosened to detach the wheel package seat assembly 7 as a whole. The installation process is the reverse of the removal process. Therefore, the accuracy of positioning the bolt 83 and the threaded connector can be improved and the assembly efficiency can be improved by adopting the C-shaped groove 811. When a plurality of screw connectors are provided in the C-shaped groove 811, the screw connectors may be nuts fixed in the C-shaped groove 811 and/or movable in the C-shaped groove 811, and thus the processing accuracy of the plurality of connecting plates 821 can be reduced, and the cost can be saved.
