Problems solved by technology
[0005] In the prior art, the partition wall is formed by installing wall panels on the outside of the aluminum alloy framework, and the partition wall is connected to the side wall and the roof by welding. Due to the complex structure of the driver's cab, the welding process is difficult when installing the partition wall. The installation efficiency is low, and the skeleton structure made of aluminum alloy is heavy, which does not meet the requirements of lightweight rail vehicles

The invention discloses a car body, which comprises a head car body and an intermediate car body. The head car body includes a bottom frame, a partition wall, a side wall and a car roof. The top of the wall is connected to the roof; the two sides and the top of the partition wall are provided with a number of U-shaped grooves distributed at intervals and the openings are vertically outward; the roof and side walls are respectively provided with connecting seats corresponding to the U-shaped grooves The connecting seat is provided with a bar-shaped hole whose extension direction is perpendicular to the extending direction of the U-shaped groove; the partition wall and the connecting seat are fixedly connected by bolts penetrating through the U-shaped groove and the bar-shaped hole. In the vehicle body provided by the present invention, the connection is firm, and the position adjustment of the roof and the side wall in the horizontal and vertical directions can be realized through the setting of the U-shaped groove and the strip hole, which is convenient for installation, and at the same time, can effectively avoid The problem of inability to assemble caused by machining errors improves the assembly efficiency of the car body. The invention also discloses a rail vehicle comprising the vehicle body.
Description
technical field [0001] The invention relates to the field of rail transit equipment, in particular to a vehicle body. Furthermore, the invention also relates to a rail vehicle comprising the above-mentioned vehicle body. Background technique [0002] Urban rail transit refers to a mode of transportation with the characteristics of large transport volume, fast speed, safety, punctuality, environmental protection, energy saving and land use, referred to as "rail transit", including subway, light rail, maglev, express rail, tram, New transportation system, etc. [0003] With the rapid development of rail transportation, people have higher and higher requirements for the strength, processing technology and manufacturing materials of rail vehicles, especially for the safety requirements of rail vehicles. [0004] The body of a rail vehicle includes a head car body and an intermediate car body, wherein both the head car body and the middle car body include an underframe, an end ...
