Abstract

The invention discloses an air source system for a railway vehicle and the railway vehicle. The air source system comprises an air supply component, a main pipeline and a plurality of branch pipelines, wherein two ends of the main pipeline are respectively connected with the air supply component; the plurality of branch pipelines are connected with the main pipeline, an air storage cylinder is arranged at the inlet end of each branch pipeline, and the air storage cylinders can be selectively communicated with or disconnected from the main pipeline; and the branch pipeline is connected with a first air spring and a second air spring, the first air spring and the second air spring are both selectively connected with the air cylinder, and a differential pressure valve is arranged between thefirst air spring and the second air spring. According to the air source system for the railway vehicle, when one of the multiple air cylinders breaks down, normal use of the other air cylinders is notaffected. The inclination angle of the railway vehicle can be prevented from being too large, so that the body of the railway vehicle is more stable.

Description

technical field [0001] The present application relates to the technical field of vehicle manufacturing, in particular to an air source system for a rail vehicle and a rail vehicle with the air source system. Background technique [0002] In order to improve the driving comfort, the air suspension system has been adopted on the existing high-end models. The air suspension system mostly adopts the air spring structure, and the control valve is used to charge and deflate the air spring, so that it can be adjusted The amount of air inside the air spring, thereby adjusting the stiffness of the air spring while the vehicle is running. In related technologies, when a single air storage component fails in the air source system of the air suspension, the use of other air springs is easily affected, and the stability of the air suspension supporting the rail vehicle is poor, so there is room for improvement. Contents of the invention [0003] This application aims to solve at least...
