Problems solved by technology

When disassembling or maintaining the running wheels, it is necessary to remove the wheel bag outer 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

Abstract

The invention discloses a rail vehicle, comprising: a floor, an opening is formed on the floor, the opening includes a wheel inspection opening and a wheel installation opening; a wheel, the wheel is arranged at the wheel installation opening, a part of the wheel passes through the wheel installation opening and Protruding from the upper surface of the floor, the upper cover of the wheel is provided with a wheel bag; the maintenance floor plate is detachably connected to the wheel inspection port, and the wheel inspection port is located at the wheel on the rail vehicle. side in the left-right direction. According to the rail vehicle of the present invention, by providing an opening on the floor including a wheel inspection opening and a wheel installation opening, and setting wheels at the wheel installation opening and a detachable inspection floor board at the wheel inspection opening, the wheel Daily inspection and maintenance can fully ensure the dustproof and sound insulation effect of the wheel bag, and ensure its sealing performance. At the same time, the wheel inspection port can be made larger, which is more convenient for inspection.

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 disassemble or maintain the running wheels on the straddle-type monorail train, firstly, a huge bogie separation device is used to separate the bogie from the car body, and then the wheel changing operation is performed under the car body. During the operation, it is necessary to lift the car body and bogie to a relatively high distance from the track beam surface to meet the space requirements for wheel changes. At the same time, it is necessary to disassemble and reinstall a large number of wiring harnesses and pipes connected to the bogie, and the workload is Big 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 train. When disassembling or maintainin...
