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 an annular groove 7 are added. The remaining parts of the air spring air circuit connection device provided in this embodiment are the same as those described above, and will not be repeated here.

[0034] In order to optimize the connection relationship between the air spring 2 and the air spring air circuit mounting part 4, a cover plate 6 is provided on the top of the air spring 2 in this embodiment, and the air spring air circuit mounting part 4 and the cover plate 6 are connected together to form a whole , or it can be considered that the air spring air circuit installation piece 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 circuit mounting part 4 is connected to the through hole to ensure the air pat...

Abstract

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 air circuit connection device for urban rail vehicles. The present invention also relates to an urban rail vehicle comprising the above-mentioned air spring air circuit connection device Background technique [0002] With the development of China's urban road traffic, the investment and use of urban rail vehicles have gradually spread to all parts of the country, and their forms are also diverse, such as subways, high-speed rails, and light rails. [0003] When the urban rail vehicle is getting off and connected, the air spring of the vehicle bogie needs to be connected with the pipeline of the vehicle chassis. At present, when the urban rail vehicle is connected to the car, the connection between the air spring of the bogie and the pipeline of the vehicle chassis is generally completed in the form of threaded connection. [0004] However, it takes ...
