Problems solved by technology

When disassembling or maintaining the running wheel, it is necessary to remove the electrical cabinet cover and dust cover of the wheel bag first. The disassembly steps are cumbersome and take a long time
Moreover, in order to facilitate the disassembly of the running wheels, the car body floor reserves a large space for the running wheels, and the sound insulation effect needs to be improved

Embodiment Construction

[0064] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary, and the embodiments of the present invention will be described in detail below.

[0065] Reference below Figure 1-Figure 27 A rail vehicle 100 according to an embodiment of the present invention is described. The rail vehicle 100 may be applied to a rail vehicle such as a straddle monorail (not shown). In the following description of the present application, the application of the rail vehicle 100 to a rail vehicle such as a straddle-type monorail is taken as an example for illustration. Of course, those skilled in the art can understand that the rail vehicle 100 can also be applied to other types of rail vehicles, and is not limited to a straddle-type monorail.

[0066] like Figure 1-Figure 27 As shown, the rail vehicle 100 according to the embodiment of the first aspect of the present invention includes a...

Abstract

The invention discloses a rail vehicle, comprising: a floor, an opening is arranged on the floor, two wheel detachable floor boards are arranged in the opening, a sub-opening is defined between the two wheel detachable floor boards, and the sub-opening Wheels are arranged at the center, and a part of the wheels passes through the sub-opening and protrudes from the upper surface of the floor. The two wheel detachable floor boards are respectively located on the radial sides of the wheel. The two wheel detachable floor boards can be connected with the floor. The wheel bag is disassembled and connected; the wheel bag, the wheel bag cover is arranged on the top of the wheel, and the wheel bag is connected with the two wheel detachable floor boards. According to the rail vehicle of the present invention, the area of ​​the entire floor is increased, and the space occupied by the wheel pack can be relatively reduced, and the weight of the wheel pack can be reduced. While ensuring the disassembly and assembly of wheels in the car, the weight of the rail vehicle is reduced, the performance of the rail vehicle is improved, and the reserved wheel space of the car body is reduced, thereby reducing the noise in the car and improving the comfort of passengers.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a rail vehicle. Background technique [0002] In the related art, in order to dismantle or maintain the running wheels on the straddle-type monorail, a huge bogie separation device is first used to separate the bogie from the vehicle body, and then the wheel change operation is performed under the vehicle body. During the operation, it is necessary to lift the car body and the bogie to a relatively high distance from the track beam surface to meet the space requirements for wheel changing. At the same time, a large number of wiring harnesses and pipes connected to the bogie need to be disassembled and reassembled, and the workload large and inefficient. [0003] In other related technologies, a detachable wheel bag that occupies a large space and is heavy is provided above the running wheels of the straddle-type monorail. When disassembling or maintaining the runnin...
