Abstract

The invention relates to a connecting structure and system of an integrated brake device for a railway vehicle and belongs to the technical field of railway vehicle manufacturing. The connecting structure of the integrated brake device for the railway vehicle comprises a brake valve, a dust collector, a middle body, an air cylinder, a support assembly and a connecting assembly. The middle body is of a plate-type structure. The brake valve and the dust collector are installed at one side of the middle body. The air cylinder and the middle body are connected through the connecting assembly. The air cylinder is installed at the other side of the middle body. The support assembly is located between the air cylinder and the middle body. The connecting structure of the integrated brake device for the railway vehicle is simple and compact in structure and capable of saving space. Brake parts are integrated on the middle body, and all the brake parts and the whole integrated brake device are connected with an external mounting base safely and reliably. According to the connecting system of the integrated brake device for the railway vehicle, by setting connection between the middle part and all the brake parts, connecting stability of the brake parts is improved and connecting safety of the connecting assembly is also improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicle manufacturing, in particular to a connection structure and system of an integrated braking device for rail vehicles. Background technique [0002] At present, the various components of the rail vehicle braking system are scattered and connected to the car body of the rolling stock. The pipeline connection is complicated and occupies a large space, which is not conducive to maintenance and maintenance. When designing rolling stock, it is necessary to determine the installation position of the braking system according to the size of the car body. [0003] In the existing rail vehicles, the braking system including various types of air cylinders is scattered and installed on the fixing frame, but there are problems that the fixing frame occupies a large space and the maintenance and disassembly of each component are inconvenient. Contents of the invention [0004] The purpose of the present i...
