Two wheel removal and mounting floor panels 5 are disposed in the opening portion 11, a sub-opening portion is defined between the two wheel removal and mounting floor panels 5, a wheel 2 is disposed at the sub-opening portion, a part of the wheel 2 passes through the sub-opening portion and protrudes from an upper surface of the floor 1, and the two wheel removal and mounting floor panels 5 are respectively located on two sides of the wheel 2 in a front-rear direction of the railway vehicle 100. Both the two wheel removal and mounting floor panels 5 are detachably connected to the floor 1. The wheel cover 3 covers an upper side of the wheel 2 and the wheel cover 3 is connected to the two wheel removal and mounting floor panels 5.
For example, referring to
When the wheel 2 needs to be removed, the wheel cover 3 may be first removed, and then the two wheel removal and mounting floor panels 5 are removed. After a sufficient space for removing the wheel 2 is reserved, the wheel 2 is removed finally. Conversely, when the wheel 2 is mounted, the wheel 2 may be first mounted, then the two wheel removal and mounting floor panels 5 are mounted, and finally the wheel cover 3 is mounted. Therefore, the wheel 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 mounting floor panels 5 located on two sides of a wheel 2 in a radial direction are disposed, a part of the wheel 2 may pass through a sub-opening portion between the two wheel removal and mounting floor panels 5, and a wheel cover 3 is connected to the two wheel removal and mounting floor panels 5, so that an area of the entire floor 1 is increased and an occupied space of the wheel cover can be relatively reduced, to reduce a weight of the wheel cover 3. When the railway vehicle 100 is a straddle-type monorail vehicle, the wheel 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
Optionally, a maximum width of the opening portion 11 is greater than the diameter of wheels 2 in the length direction of the floor 1. Therefore, after the two wheel removal and mounting floor panels 5 are removed, the wheel 2 can be further conveniently removed in the vehicle. Optionally, a longitudinal width of the opening portion 11 is greater than the diameter of the wheel 2 by at least 100 mm or more. Because the wheel 2 has a large weight, which is about 200 kg, the wheel 2 has a shaking amount when the wheel 2 is removed, and such arrangement better facilitates removal of the wheel 2.
According to some embodiments of the present disclosure, as shown in
According to further embodiments of the present disclosure, referring
Optionally, the sealing member 124 is a sealing rubber member. For example, the sealing member 124 may be a sealing rubber pad. Due to elasticity, a rubber structure can better seal the gap between the wheel removal and mounting floor panel 5 and the floor 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
Further, as shown in
Optionally, referring to

For example, the wheel cover 3 and the seat 6 as a whole may also be formed as a seat in an upper part, and the bottom of the wheel cover 3 and the seat 6 as a whole is provided with an upwardly concave portion, where a part of the wheel 2 is located in the concave portion. Specifically, the wheel cover 3 may include a seat part and a backrest part. The seat part covers the upper side of the wheel 2, the concave portion for accommodating the part of the wheel 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. The wheel cover 3 may be a hollow structure with the bottom being open. In this case, the concave portion below the wheel cover 3 is configured to accommodate the part of the wheel 2 protruding from the upper surface of the floor 1, and an upper part of the wheel cover 3 is for the passenger to directly sit. With this arrangement, the wheel cover 3 can be made relatively small and has a light weight.
Optionally, as shown in
Further, referring to
Specifically, as shown in
Certainly, the bolt structure 8 may also be located outside the wheel cover and seat assembly 7. A groove with the top being open is formed in the floor 1, the bolt 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, the bolt structure 8 is arranged outside the wheel cover and seat assembly 7, to facilitate removal and mounting. Disposing of the cover plate allows the bolt structure 8 to be well hidden below the cover plate, which can similarly ensure the aesthetics of the entire 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
For example, when the threaded connector in the C-shaped groove 811, for example, the nut in the C-shaped groove 811, is movable, during mounting and removal of the wheel cover and seat assembly 7, the wheel cover and seat assembly 7 may move leftward and rightward along the C-shaped groove 811. When an assembly error exists, the assembly error can be reduced by moving the wheel cover and seat assembly 7 leftward and rightward, so that the wheel cover and seat assembly 7 is easy to remove. In addition, as shown in
