Problems solved by technology

But this is not what we want. This kind of change requires recalculation, testing and application verification, which is not only time-consuming and labor-intensive, but also increases costs and brings new safety hazards.
[0008] Brake cylinders are also commonly used. For brake cylinder manufacturers, it is a mature general-purpose structure with a large sales volume. If the interface is changed to adapt to the original interface of the framework, on the one hand, the difficulty of changing is more difficult than that of the existing framework. , on the other hand, it will also become a dedicated structure, which will take a lot of manpower, material resources and a long time, thereby increasing the manufacturing cost

Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0041] Such as figure 1 and Figure 6 As shown, the existing frame 1 includes three first mounting holes 11 and three brake bushings, and the three brake bushings are respectively the first brake bushing 12, the second brake bushing 13 and the third brake bushing. Casing 14. Wherein the second brake sleeve 13 and the third brake sleeve 14 each have a positioning matching surface 331, and the two positioning matching surfaces 331 of the second brake sleeve 13 and the third brake sleeve 14 form a 90° included angle.

[0042] Such as figure 2 As shown, the common brake cylinder 2 includes four second mounting holes 21 .

[0043] A transition interface plate for a brake cylinder of a bogie unit, used for the connection between an existing frame 1 and a common brake cylinder 2, including a transition between the existing fr...

Abstract

The invention discloses a transition interface plate for a brake cylinder of a bogie unit and a connection method, which is used for the connection between an existing frame and a common brake cylinder, and comprises a transition interface plate body, on which three frames are arranged Mounting holes, four brake cylinder mounting holes and right-angle bosses; the three frame mounting holes are respectively matched with the three first mounting holes, and the existing frame is fixedly connected with the transition interface plate body through the first bolts; The moving cylinder mounting holes are respectively matched with the four second mounting holes, and the common brake cylinder is fixedly connected with the transition interface plate body through the second bolt; the two right-angled sides of the right-angled boss can be connected with the two Brake sleeves fit snugly. After adopting the above structure and method, the two can be effectively matched without changing the existing frame or the structure of the commonly used brake cylinder, so that the utility model has strong versatility, low manufacturing cost and high popularization value. In addition, the right-angle boss can also play the functions of positioning, bearing and anti-shearing of bolts.

Description

technical field [0001] The invention relates to a connection device and a connection method in the production process of a rail vehicle bogie, in particular to a transition interface plate for a bogie unit brake cylinder and a connection method. Background technique [0002] In the production process of rail vehicle bogies, there are one or more types of bogies (hereinafter referred to as existing frames) that have been verified in use and have a mature structure. The connection interface between the existing frame and the brake cylinder is as follows: figure 1 As shown, since the original design uses a 3-hole interface, the brake cylinder used in conjunction with it has always been a dedicated 3-hole interface. [0003] However, the brake cylinders (hereinafter referred to as commonly used brake cylinders) sold in large quantities on the market, such as figure 2 As shown, the interface is usually a 4-hole interface. [0004] Since the interface between the existing frame...
