Embodiment approach
[0033] The second specific embodiment provided by the present invention is improved on the basis of the first specific embodiment, specifically: a cover plate 6 and a ring groove 7 are added. The rest of the air spring pneumatic connection device provided in this embodiment is the same as the above content, and will not be repeated here.
[0034] In order to optimize the connection relationship between the air spring 2 and the air spring air path mounting member 4, in this embodiment, a cover plate 6 is provided on the top of the air spring 2. The air spring air path mounting member 4 and the cover plate 6 are connected together to form a whole , Or it can be considered that the air spring air path mounting member 4 is a sub-component of the cover plate 6. The cover plate 6 covers the top of the air spring 2 and has a through hole, and the inside of the air spring air path mounting member 4 is connected with the through hole to ensure the air path between the air spring 2 and the...

The invention discloses an air spring air way connecting device of an urban rail vehicle. The air spring air way connecting device comprises an air way pipe arranged on a vehicle body chassis, and an air spring arranged below a vehicle body, and further comprises an air spring air way connecting piece and an air spring air way installing piece. The air spring air way connecting piece is provided with a cavity and an opening. The air way pipe is connected with the side wall of the air spring air way connecting piece and communicated with the cavity. The air spring air way installing piece is arranged on the air spring and is hollow. One end of the air spring air way installing piece is communicated with the air spring. The other end of the air spring air way installing piece is communicated with the cavity. A seal ring for being closely attached to the inner wall of the air spring air way connecting piece is arranged around the outer wall of the air spring air way installing piece. By means of the air spring air way connecting device of the urban rail vehicle, when the air spring air way connecting device gets off a vehicle to be connected with the vehicle, the air spring air way installing piece is inserted into the opening of the air spring air way connecting piece; the seal ring is closely attached to the inner wall of the opening of the air spring air way connecting piece, and therefore the smoothness and sealing performance of air way connection are ensured.
Description
Technical field [0001] The invention relates to the technical field of locomotive engineering, in particular to an air spring gas circuit connection device for urban rail vehicles. The present invention also relates to an urban rail vehicle including the above-mentioned air spring gas path connecting device Background technique [0002] With the development of urban road transportation in China, the investment and use of urban rail vehicles have gradually spread throughout the country, and their forms are also diverse, such as subways, high-speed rails, and light rails. [0003] When the urban rail vehicle is dropped and connected, the air spring of the vehicle bogie and the vehicle underframe pipeline are required to be air connected. At present, when urban rail vehicles are connected for landing, the connection between the air spring of the bogie and the pipeline of the vehicle underframe is generally completed through a threaded connection. [0004] However, it takes a lot of ti...
