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, a first branch pipeline, a secondbranch pipeline, at least one third branch pipeline and an air distribution pipe, wherein two ends of the main pipeline are respectively connected with the air supply component; the first branch pipeline and the second branch pipeline are respectively connected with the main pipeline, a first air storage cylinder is arranged at the inlet end of the first branch pipeline, a second air storage cylinder is arranged at the inlet end of the second branch pipeline, and the first air storage cylinder and the second air storage cylinder can be selectively communicated with or disconnected from the main pipeline; the at least one third branch pipeline is connected with the air distribution pipe; and the first branch pipeline, the second branch pipeline and the third branch pipeline are respectivelyconnected with a first air spring and a second air spring, and a differential pressure valve is arranged between the first air spring and the second air spring. According to the air source system forthe railway vehicle, when the air source system leaks air and breaks down, the fault position can be rapidly positioned, and the inclination angle of the railway vehicle can be prevented from being too large.
Description
technical field [0001] The present application relates to the technical field of vehicle manufacturing, in particular to an air source system for rail vehicles and a 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, each gas supply part of the air suspension is controlled at the same time, and when a single gas storage part fails, it will affect the use of other air springs, and the operator cannot quickly determine the fault location, and the balance on both sides of the rail vehicle cannot be guaranteed. There is an improved space. Conten...
