Description

Technical Field

[0001] The invention relates to the technical field of height valves, and in particular to an integral height valve installation structure with integrated air supply function. Background Art

[0002] Most existing bogies with bolsters use the bolster as an additional air chamber for the air spring. The height valve is installed on the bolster, and the height valve is connected to the additional air chamber interface on the bolster through a pipeline. Since the height valve mounting seat and the additional air chamber interface are independently welded on the bolster, the positioning accuracy between the height valve mounting seat and the additional air chamber interface cannot be guaranteed due to the limitations of the welding process itself, which often leads to difficulties in connecting the pipeline between the height valve and the additional air chamber. Especially when the height valve mounting seat and the additional air chamber interface are close, the installation quality cannot be guaranteed due to the short connecting pipeline and limited adjustment space.

[0003] At the same time, the height valve mounting seat and the additional air chamber interface are welded and processed together with the bolster. On the one hand, sufficient processing allowance needs to be reserved, and on the other hand, it will also cause cumbersome procedures and low production efficiency.

[0004] Therefore, based on the above technical problems, technicians in this field urgently need to develop an integrated height valve installation structure with integrated air supply function. Summary of the invention

[0005] The object of the present invention is to provide an integral height valve installation structure with integrated air supply function, which is intended to solve the problem of difficulty in pipe connection caused by low positioning accuracy of the height valve installation seat and the additional air chamber interface after welding, and to avoid the use of the height valve installation seat and the additional air chamber interface after welding and then being processed as a whole with the pillow beam, thereby resulting in cumbersome production processes and low efficiency.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0011] The additional air chamber connector is provided with an additional air chamber interface, and the additional air chamber interface cooperates with the air hole reserved for the additional air chamber of the air spring on the corresponding side of the bolster;

[0012] The height valve installed on the height valve installation body is communicated with the additional air chamber interface through a pipe fitting.

[0013] Furthermore, two circular holes are provided on the height valve mounting body;

[0014] The height valve mounting body is used to mount the height valve via two circular holes.

[0015] Furthermore, the mounting structure is fixed to the bolster by welding.

[0016] Furthermore, the inner space of the mounting structure is formed into a sealed space through the weld between the mounting structure and the periphery of the bolster.

[0017] Furthermore, the air spring additional air chamber is formed at both ends of the bolster in the length direction;

[0018] The lower part of the air spring additional air chamber of the bolster is connected to the air spring;

[0019] The vertical plate on the side of the additional air chamber of the air spring of the bolster is connected to the mounting structure, and the air hole is opened on the vertical plate.

[0020] Furthermore, when the height valve is installed on the height valve installation body through the circular hole, the air outlet of the height valve is located at the top and close to one side of the additional air chamber connecting body;
