- The embodiments of the present disclosure are described below in detail. Examples of the embodiments are shown in the accompanying drawings, and same or similar reference signs in all the accompanying drawings indicate same or similar components or components having same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present disclosure and cannot be construed as a limitation to the present disclosure.
- The following describes a
railway vehicle 100 according to the embodiments of the present disclosure with reference toFIG. 1 toFIG. 27 . Therailway vehicle 100 is a straddle-type monorail vehicle (not shown in the figure). In the following description of this application, take therailway vehicle 100 as the straddle-type monorail vehicle as an example. Certainly, a person skilled in the art may understand that, therailway vehicle 100 is another type of railway vehicle, which is not limited to the straddle-type monorail vehicle. - As shown in
FIG. 1 toFIG. 27 , therailway vehicle 100 according to an embodiment of a first aspect of the present disclosure includes afloor 1 and awheel cover 3. - Specifically, an opening
portion 11 is provided on thefloor 1. Two wheel removal and mountingfloor panels 5 are disposed in the openingportion 11, a sub-opening portion is defined between the two wheel removal and mountingfloor panels 5, awheel 2 is disposed at the sub-opening portion, a part of thewheel 2 passes through the sub-opening portion and protrudes from an upper surface of thefloor 1, and the two wheel removal and mountingfloor panels 5 are respectively located on two sides of thewheel 2 in a front-rear direction of therailway vehicle 100. Both the two wheel removal and mountingfloor panels 5 are detachably connected to thefloor 1. Thewheel cover 3 covers an upper side of thewheel 2 and thewheel cover 3 is connected to the two wheel removal and mountingfloor panels 5. - For example, referring to
FIG. 1 toFIG. 3 ,FIG. 5 , andFIG. 16 , thefloor 1 extends in a horizontal direction, and the openingportion 11 may run through thefloor 1 in an up-down direction. The two wheel removal and mountingfloor panels 5 are disposed on two sides of the openingportion 11 in a length direction of thefloor 1 at intervals. In this case, a width of the sub-opening portion in the length direction of thefloor 1 is less than a width of the openingportion 11 in the length direction of thefloor 1. Thewheel 2 is disposed at the sub-opening portion through penetration, an upper part of thewheel 2 is located above thefloor 1, and a lower part of thewheel 2 is located below thefloor 1. Therefore, by disposing the two wheel removal and mountingfloor panels 5, an area of theentire floor 1 is increased, and by fixing thewheel cover 3 to the two wheel removal and mountingfloor panels 5, a volume of thewheel cover 3 is reduced and a weight and an occupied space of the wheel cover are reduced, thereby implementing mounting of a small wheel cover and relatively increasing a space for a passenger. When therailway vehicle 100 is a straddle-type monorail vehicle, in a case of a same quantity of passengers, this solution can reduce a length of the entire vehicle, reduce a weight of the entire vehicle, and further improve the performance of the entire vehicle. In addition, distances between thewheel 2 and the two wheel removal and mountingfloor panels 5 are relatively short, and a wheel space (that is, the sub-opening portion) reserved on a vehicle body of the railway vehicle such as the straddle-type monorail vehicle may be reduced, so that noise in the vehicle can be reduced, thereby improving the comfort of seat for passengers. Thewheel 2 may be a walking wheel of the railway vehicle such as the straddle-type monorail vehicle. - When the
wheel 2 needs to be removed, thewheel cover 3 may be first removed, and then the two wheel removal and mountingfloor panels 5 are removed. After a sufficient space for removing thewheel 2 is reserved, thewheel 2 is removed finally. Conversely, when thewheel 2 is mounted, thewheel 2 may be first mounted, then the two wheel removal and mountingfloor panels 5 are mounted, and finally thewheel cover 3 is mounted. Therefore, thewheel 2 can be removed and mounted in the vehicle. Compared with a conventional manner of changing a wheel outside the vehicle, the manner of removing and mounting the wheel in the vehicle is convenient in removal and mounting and is time-saving and labor-saving. - According to the
railway vehicle 100 provided in the embodiments of the present disclosure, two detachable wheel removal and mountingfloor panels 5 located on two sides of awheel 2 in a radial direction are disposed, a part of thewheel 2 may pass through a sub-opening portion between the two wheel removal and mountingfloor panels 5, and awheel cover 3 is connected to the two wheel removal and mountingfloor panels 5, so that an area of theentire floor 1 is increased and an occupied space of the wheel cover can be relatively reduced, to reduce a weight of thewheel cover 3. When therailway vehicle 100 is a straddle-type monorail vehicle, thewheel 2 is removed and mounted in the vehicle, a weight of the railway vehicle such as the straddle-type monorail vehicle is reduced, the performance of the railway vehicle such as the straddle-type monorail vehicle is improved, and a wheel space reserved on a vehicle body is reduced, thereby reducing noise in the vehicle and improving the comfort of seat for passengers. - According to some embodiments of the present disclosure, as shown in
FIG. 10 andFIG. 11 , a central axis of thewheel 2 is lower than an upper surface of thefloor 1. In this case, the central axis of thewheel 2 is located below a horizontal plane of thefloor 1. A size of a part of thewheel 2 located above thefloor 1 is less than a size of a part of the wheel located below thefloor 1. Therefore, a part of thewheel 2 such as a walking wheel protruding from thefloor 1 is relatively small, so that a relatively low floor is implemented and a proportion of a passenger space occupied by the protruding part of the walking wheel is reduced, to improve the comfort of seat. Referring toFIG. 8 , a distance between the two wheel removal and mountingfloor panels 5 is less than a diameter of thewheel 2 in a length direction of thefloor 1. Such arrangement can further increase the area of theentire floor 1 and reduce the size of the part of thewheel 2 protruding from thefloor 1, so that the occupied space of thewheel cover 3 is further reduced and the weight of thewheel cover 3 is further reduced. Therefore, the wheel space reserved on the vehicle body is further reduced, the noise in the vehicle is further reduced, and the structure of the entire railway vehicle such as the straddle-type monorail vehicle can be more compact, thereby further improving the performance of the railway vehicle such as the straddle-type monorail vehicle. - Optionally, a maximum width of the opening
portion 11 is greater than the diameter ofwheels 2 in the length direction of thefloor 1. Therefore, after the two wheel removal and mountingfloor panels 5 are removed, thewheel 2 can be further conveniently removed in the vehicle. Optionally, a longitudinal width of the openingportion 11 is greater than the diameter of thewheel 2 by at least 100 mm or more. Because thewheel 2 has a large weight, which is about 200 kg, thewheel 2 has a shaking amount when thewheel 2 is removed, and such arrangement better facilitates removal of thewheel 2. - According to some embodiments of the present disclosure, as shown in
FIG. 10 andFIG. 11 , astep structure 13 is disposed on an edge of thefloor 1 located at the openingportion 11, and one side of each wheel removal and mountingfloor panel 5 away from thewheel 2 is disposed on thestep structure 13, and an upper surface of an overhaulingfloor panel 4 is flush with the upper surface of thefloor 1. For example, thestep structure 13 may include a firstupper surface 131 and a secondupper surface 132 that are not located on a same plane. The firstupper surface 131 is higher than the secondupper surface 132 and the firstupper surface 131 is located on one side of the secondupper surface 132 away from thewheel 2. During mounting, a part of the wheel removal and mountingfloor panel 5 extends to an upper side of the secondupper surface 132 and matches the secondupper surface 132, and an upper surface of the wheel removal and mountingfloor panel 5 is flush with the firstupper surface 131. Therefore, it can be effectively ensured that theentire floor 1 is located on the same plane. - According to further embodiments of the present disclosure, referring
FIG. 10 andFIG. 11 , a sealingmember 124 is disposed between each wheel removal and mountingfloor panel 5 and thefloor 1. For example, in examples ofFIG. 10 andFIG. 11 , one side of each wheel removal and mountingfloor panel 5 away from thewheel 2 extends to the upper side of thefloor 1 such as the secondupper surface 132. The sealingmember 124 is disposed between a lower surface of one side of each wheel removal and mountingfloor panel 5 away from thewheel 2 and the secondupper surface 132 of thefloor 1. With such arrangement, one side of each wheel removal and mountingfloor panel 5 away from thewheel 2 may be propped to thefloor 1, noise transmission can be reduced, and mounting of the sealingmember 124 is facilitated. Because the sealingmember 124 may seal a gap between the wheel removal and mountingfloor panel 5 and thefloor 1, noise from a lower vehicle body of the railway vehicle such as the straddle-type monorail vehicle can be effectively isolated. - Optionally, the sealing
member 124 is a sealing rubber member. For example, the sealingmember 124 may be a sealing rubber pad. Due to elasticity, a rubber structure can better seal the gap between the wheel removal and mountingfloor panel 5 and thefloor 1, to achieve a good sound insulation effect. However, the present disclosure is not limited thereto. - According to some embodiments of the present disclosure, referring to
FIG. 1 toFIG. 3 andFIG. 12 toFIG. 14 , aseat 6 is disposed on thewheel cover 3. Theseat 6 is configured for a passenger to sit on. Such arrangement effectively utilizes a space occupied by thewheel 2 protruding from thefloor 1. Specifically, for example, in examples ofFIG. 1 toFIG. 3 andFIG. 12 toFIG. 14 , theseat 6 is fixedly connected to the top of thewheel cover 3, thewheel cover 3 covers an upper side of thewheel 2, and thewheel cover 3 and theseat 6 are detachably connected to thefloor 1 as a whole. In this case, thewheel cover 3 and theseat 6 may be an integrated structure, and theseat 6 and thewheel cover 3 may be integrally formed. Certainly, theseat 6 and thewheel cover 3 may alternatively be separately processed and formed and then connected as a whole through welding or the like. Therefore, thewheel cover 3 is designed to be compatible with theseat 6, and thewheel cover 3 and theseat 6 as a whole can simultaneously protect thewheel 2 and allow passengers to take. When requiring to be mounted or removed, thewheel cover 3 and theseat 6 only need to be mounted on thefloor 1 or removed from thefloor 1 as a whole. Compared with a conventional manner of requiring to first remove the seat and then remove the wheel cover, the manner is convenient in removal and is time-saving and labor-saving without a problem of destroying a mounting structure between the seat and the wheel cover and can implement mounting and removal of thewheel 2 in a compartment. - Further, as shown in
FIG. 15 , anaccommodating space 32 with the bottom being open and concave upward is formed on thewheel cover 3, and theaccommodating space 32 is configured to accommodate a part of thewheel 2. Therefore, a part of thewheel 2 protruding from an upper surface of thefloor 1 may be well covered by thewheel cover 3. - Optionally, referring to
FIG. 15 , a top wall of theaccommodating space 32 is formed as an arc-shaped wall adapted to the shape of thewheel 2. For example, thewheel cover 3 is formed as an upwardly protruding arch-shaped structure, which is preferably adapted to the shape of thewheel 2. With this arrangement, it is ensured that the part of thewheel 2 can be well accommodated in theaccommodating space 32, and the space occupied by thewheel cover 3 in the compartment can be relatively reduced. - Certainly, the present disclosure is not limited thereto. The
wheel cover 3 may further be formed in the form of seat 6 (not shown in the figure). For example, thewheel cover 3 and theseat 6 as a whole may also be formed as a seat in an upper part, and the bottom of thewheel cover 3 and theseat 6 as a whole is provided with an upwardly concave portion, where a part of thewheel 2 is located in the concave portion. Specifically, thewheel cover 3 may include a seat part and a backrest part. The seat part covers the upper side of thewheel 2, the concave portion for accommodating the part of thewheel 2 is formed on the bottom of the seat part, a top surface of the seat part is a horizontal plane for the passenger to sit, and the backrest part extends upward from the top surface of the seat part for the passenger to recline. Thewheel cover 3 may be a hollow structure with the bottom being open. In this case, the concave portion below thewheel cover 3 is configured to accommodate the part of thewheel 2 protruding from the upper surface of thefloor 1, and an upper part of thewheel cover 3 is for the passenger to directly sit. With this arrangement, thewheel cover 3 can be made relatively small and has a light weight. - Optionally, as shown in
FIG. 16 toFIG. 20 , thewheel cover 3 and theseat 6 are collectively referred to as a wheel cover andseat assembly 7 as a whole. The wheel cover andseat assembly 7 is detachably connected to thefloor 1 by abolt structure 8. Therefore, removal and mounting are convenient, and the connection through thebolt structure 8 is reliable, which is suitable for mass production and low in cost. - Further, referring to
FIG. 16 toFIG. 20 , thebolt structure 8 is located in the wheel cover andseat assembly 7. A wheelcover mounting opening 33 is formed in a lower portion of the wheel cover andseat assembly 7. The wheelcover mounting opening 33 is adjacent to thebolt structure 8, and adetachable sealing plate 34 is disposed at the wheelcover mounting opening 33. Herein, it should be noted that, a direction “inside” may be understood as a direction toward an inner center of the wheel cover andseat assembly 7, and a direction opposite to the “inside” is defined as “outside”, that is, a direction away from the inner center of the wheel cover andseat assembly 7. With this arrangement, thebolt structure 8 may be well hidden inside the wheel cover andseat assembly 7, to ensure the compactness of theentire railway vehicle 100. During removal and mounting, the sealingplate 34 at the openingportion 11 may be opened, to tighten or loosen thebolt structure 8. - Specifically, as shown in

Thefastener 341 includes arod portion 3411 and anend portion 3412, where one end of therod portion 3411 is connected to the sealingplate 34 and theend portion 3412 is connected to the other end of therod portion 3411. A maximum size of theend portion 3412 in a cross section of therod portion 3411 is greater than a maximum size of therod portion 3411 in the cross section of therod portion 3411, and theend portion 3412 may be formed as a long strip shape. At least one mountingplate 331 is disposed at a position of the wheel cover andseat assembly 7 corresponding to the wheelcover mounting opening 33, a lockingstructure 332 is disposed on the mountingplate 331, and anelongated hole 3321 adapted to a shape of theend portion 3412 is formed in the lockingstructure 332. During mounting, after passing through theelongated hole 3321 on the lockingstructure 332 on the mountingplate 331, theend portion 3412 of thefastener 341 on the sealingplate 34 rotates by a specific angle. In this case, theend portion 3412 is staggered with theelongated hole 3321 on the lockingstructure 332, to reliably mount the sealingplate 34 at the wheelcover mounting opening 33. During removal, only thefastener 341 needs to be rotated, so that theend portion 3412 of the fastener is aligned with theelongated hole 3321 of the lockingstructure 332. Subsequently, the sealingplate 34 is removed outward. In this case, thefastener 341 is withdrawn from theelongated hole 3321 of the lockingstructure 332 and the mountingplate 331. - Certainly, the
bolt structure 8 may also be located outside the wheel cover andseat assembly 7. A groove with the top being open is formed in thefloor 1, thebolt structure 8 is located in the groove, and a detachable cover plate (not shown in the figure) is disposed on the top of the groove. Therefore, thebolt structure 8 is arranged outside the wheel cover andseat assembly 7, to facilitate removal and mounting. Disposing of the cover plate allows thebolt structure 8 to be well hidden below the cover plate, which can similarly ensure the aesthetics of theentire railway vehicle 100. - It can be understood that the sealing
plate 34 and the cover plate may further be pivotally connected to a corresponding position by a hinge structure or the like, or may be clamped through a buckle structure or the like. However, the present disclosure is not limited thereto. - Specifically, referring to

When requiring to be mounted or removed, the entire wheel cover andseat assembly 7 is removed. Specifically, the wheel cover andseat assembly 7 is fixed to the C-shapedgroove 811 of the first connectingmember 81 on thefloor 1 by using thebolt 83. When the wheel cover andseat assembly 7 needs to be removed, the sealingplate 34 or the cover plate for decoration is first removed, and then thebolt 83 such as a fastening bolt is loosened, so that the entire wheel cover andseat assembly 7 is removed. A mounting process is opposite to the removal process. Therefore, by using the C-shapedgroove 811, the accuracy of positioning thebolt 83 and the threaded connector can be improved, and the assembly efficiency is improved. When a plurality of threaded connectors are disposed in the C-shapedgroove 811, the threaded connectors may be nuts fixed to the C-shapedgroove 811 or movable in the C-shapedgroove 811. In this case, machining precision of a plurality of connectingplates 821 can be reduced, and the costs can be saved. - For example, when the threaded connector in the C-shaped
groove 811, for example, the nut in the C-shapedgroove 811, is movable, during mounting and removal of the wheel cover andseat assembly 7, the wheel cover andseat assembly 7 may move leftward and rightward along the C-shapedgroove 811. When an assembly error exists, the assembly error can be reduced by moving the wheel cover andseat assembly 7 leftward and rightward, so that the wheel cover andseat assembly 7 is easy to remove. In addition, as shown inFIG. 27 , when a positioning destination of the wheel cover andseat assembly 7 is a spacer in the railway vehicle such as the straddle-type monorail vehicle, after the wheel cover andseat assembly 7 is mounted in the C-shapedgroove 811, the wheel cover andseat assembly 7 may be pushed toward the spacer, so that the wheel cover andseat assembly 7 is seamlessly propped to the spacer. When the wheel cover andseat assembly 7 needs to be removed, the wheel cover andseat assembly 7 is pushed away from the spacer, so that the wheel cover andseat assembly 7 is removed. - As shown in

The two wheel removal and mountingfloor panels 5 are respectively supported on upper surfaces of the at least twofixed supports 12, and the two wheel removal and mountingfloor panels 5 are respectively detachably connected to the at least twofixed supports 12. With this arrangement, the fixed supports 12 can reliably support the wheel removal and mountingfloor panels 5, so that thewheel cover 3 can be more reliably mounted on the wheel removal and mountingfloor panels 5. - Specifically, as shown in
FIG. 3 ,FIG. 4 , andFIG. 6 toFIG. 11 , each fixedsupport 12 includes: a fixedportion 121 and asupport portion 122. The fixedportion 121 is connected to theside wall 113 of the openingportion 11, one end of thesupport portion 122 is fixedly connected to the top of the fixedportion 121, and the other end of thesupport portion 122 horizontally extends toward thewheel 2. The wheel removal and mountingfloor panel 5 is supported on an upper surface of thesupport portion 122, and the wheel removal and mountingfloor panel 5 is detachably connected to thesupport portion 122. For example, in examples ofFIG. 4 andFIG. 7 , both the fixedportion 121 and thesupport portion 122 may be plate-shaped structures, the fixedportion 121 and thesupport portion 122 are generally L-shaped as a whole, and the fixedportion 121 and thesupport portion 122 may be processed and formed as a whole. For example, the fixedportion 121 and thesupport portion 122 may be formed by bending a flat plate, and the fixedportion 121 may be detachably connected to theside wall 113 of the openingportion 11 by a bolt or the like, so that the entire fixedsupport 12 is fixed to thefloor 1, achieving convenient mounting and a reliable connection. The upper surface of thesupport portion 122 can support the wheel removal and mountingfloor panel 5, and thehorizontal support portion 122 facilitates connection between the support portion and the wheel removal and mountingfloor panel 5, so that the assembly efficiency can be improved. - For example, in
FIG. 1 toFIG. 5 , each wheel removal and mountingfloor panel 5 is supported and fixed by two fixedsupports 12, and the two fixedsupports 12 are respectively located on two ends of the wheel removal and mountingfloor panel 5 in a length direction. Herein, the two fixedsupports 12 are for the purpose of exemplary description. However, after reading the technical solution of this application, a person of ordinary skill can obviously understand that the solution is applied to the technical solution of three or morefixed supports 12, which also falls within the protection scope of the present disclosure. - Optionally, referring to
FIG. 4 ,FIG. 8 , andFIG. 9 , the upper surface of thesupport portion 122 is lower than the upper surface of thefloor 1 and a distance between the upper surface of thesupport portion 122 and the upper surface of thefloor 1 is equal to a thickness of the wheel removal and mountingfloor panel 5. In this case, the upper surface of thesupport portion 122 is lower than the upper surface of thefloor 1, and after the wheel removal and mountingfloor panel 5 is mounted on the fixedsupport 12, an upper surface of the wheel removal and mountingfloor panel 5 may be flush with the upper surface of thefloor 1. - Optionally, as shown in
FIG. 4 , a width of thesupport portion 122 of the fixedsupport 12 is greater than half of a width of the wheel removal and mountingfloor panel 5. In this way, the floor panel can be supported more reliably. Similarly, to improve the stability of the support for the wheel removal and mountingfloor panel 5, one end of the wheel removal and mountingfloor panel 5 may further be configured in a curved edge or a bevel, as shown inFIG. 4 . - Further, each fixed
support 12 further includes: at least one reinforcingrib 123. The reinforcingrib 123 is connected between a lower surface of thesupport portion 122 and a surface on one side of the fixedportion 121 adjacent towheels 2, as shown inFIG. 4 ,FIG. 7 , andFIG. 9 . Therefore, by disposing the reinforcingrib 123, a structural strength of the fixedsupport 12 can be improved. Optionally, the reinforcingrib 123 may be a plate-shaped structure. Certainly, the reinforcingrib 123 may alternatively be a rod-shaped structure (not shown in the figure). However, the present disclosure is not limited thereto. - According to some embodiments of the present disclosure, referring to
FIG. 8 andFIG. 9 , an avoidingopening 1231 is formed in the reinforcingrib 123, and the avoidingopening 1231 is located at a joint between thesupport portion 122 and the fixedportion 121. For example, in an example ofFIG. 9 , the avoidingopening 1231 may be a triangular notch. In this case, a gap exists between the reinforcingrib 123 and the corresponding joint between thesupport portion 122 and the fixedportion 121. Such arrangement can avoid stress concentration on the joint between thesupport portion 122 and the fixedportion 121 and improve the support reliability of the fixedsupport 12. - Optionally, the wheel removal and mounting
floor panel 5 is connected to thesupport portion 122 by a bolt. Therefore, removal and mounting are convenient, the bolt structure is simple, the connection is reliable, and the costs are low. - Optionally, the fixed

Therefore, the thickness t is set to meet 30 mm≤t≤50 mm, it is ensured that a strength requirement of the railway vehicle such as the straddle-type monorail vehicle on thefloor 1 is met and the costs can be saved. For example, when the thickness t is less than 30 mm, the thickness of the wheel removal and mountingfloor panel 5 is relatively small, which may not meet the strength requirement of the railway vehicle such as the straddle-type monorail vehicle on thefloor 1, that is, deformation or cracking may occur when a plurality of passengers stands on the floor, easily resulting in a safety hazard. When the thickness t is greater than 50 mm, the thickness of the wheel removal and mountingfloor panel 5 is relatively large. In this case, the entire wheel removal and mountingfloor panel 5 is heavy, and the costs are high. Further, optionally, the thickness t meets: t=30 mm. - Optionally, both the two wheel removal and mounting
floor panels 5 are aluminum or steel. An aluminum material and a steel material can meet the strength requirement well, and the two materials are widely used with relatively low costs. In addition, the weight of the aluminum material is relatively light, which can meet the lightweight design. However, the present disclosure is not limited thereto. - It can be understood that a shape of each wheel removal and mounting
floor panel 5 may include a straight edge shown inFIG. 4 or may include an arc-shaped or ellipse arc-shaped edge or the like.

Therefore, after the overhaulingfloor panel 4 is removed, thewheel 2 may be overhauled by using thewheel access panel 111. Specifically, when thewheel 2 needs to be overhauled, for example, daily tire pressure detection, tire inflation and deflation, and pattern depth measurement are performed on thewheel 2 such as a walking wheel, the overhaulingfloor panel 4 may be removed from thefloor 1, and thewheel access panel 111 is exposed. In this case, thewheel 2 in thewheel mounting opening 112 may be viewed and operated through thewheel access panel 111, to overhaul and maintain thewheel 2. Compared with a conventional manner in which access panels are respectively disposed on the wheel cover outer cover and the dustproof cover, in the manner, for example, when thewheel cover 3 includes the wheel coverouter cover 35 and thedustproof cover 31, no access panel needs to be disposed on the wheel coverouter cover 35 and thedustproof cover 31, so that the dustproof and sound insulation effects of thedustproof cover 31 can be ensured. In addition, thefloor panel 4 can be made large, to increase an overhauling space (that is, the wheel access panel 111) for thewheel 2, thereby facilitating the daily overhauling and maintenance on thewheel 2. - Referring to
FIG. 1 toFIG. 3 , thewheel access panel 111 is located on one side of thewheel 2 in a left-right direction of therailway vehicle 100. This arrangement is convenient for maintenance personnel to perform operations such as tire pressure detection, tire inflation and deflation, and pattern depth measurement on thewheel 2 such as the walking wheel in thewheel access panel 111. - Optionally, a longitudinal maximum width of the
wheel access panel 111 is greater than the diameter of thewheel 2 For example, a width of thewheel access panel 111 is greater than the diameter of thewheel 2 in the length direction of thefloor 1, and a size of thewheel access panel 111 is relatively large, so that daily overhauling and maintenance on thewheel 2 can be more convenient. - According to further embodiments of the present disclosure, referring to
FIG. 1 toFIG. 4 , the overhaulingfloor panel 4 may be mounted at the openingportion 11 by using at least onefixed support 12. Further, as shown inFIG. 1 toFIG. 4 , somefixed supports 12 can support both the overhaulingfloor panel 4 and the wheel removal and mountingfloor panel 5. In this way, a quantity of fixedsupports 12 can be reduced, and the overhaulingfloor panel 4 and the wheel removal and mountingfloor panel 5 can be more tightly and neatly connected. - Still further, to reduce noise transmission, a sealing
member 124 may also be disposed between the overhaulingfloor panel 4 and thefloor 1, and the sealingmember 124 may be disposed between a lower surface of the overhaulingfloor panel 4 and the upper surface of thefloor 1, as shown inFIG. 10 andFIG. 11 . - A railway vehicle such as a straddle-type monorail vehicle according to embodiments of a second aspect of the present disclosure includes the
