车钩缓冲装置是车辆最基本也是最重要的部件之一，因此,有必要设计建造性能

The coupler buffer device is one of the most basic and important parts of the vehicle. Therefore, it is necessary to design and build a coupler buffer device maintenance process line with excellent performance and complete functions to meet the requirements of the coupler buffer device maintenance process. This paper adopts field investigation method, literature research method, exploratory research method and other research methods, implements the combination of theoretical knowledge research and equipment application research, consults literature data, conducts in-depth research and analysis of scientific and reasonable policies, and clarifies optimization ideas. This article briefly introduces the development of coupler buffer devices, summarizes the experience rules, and puts forward some suggestions for future development directions. In this article, the first is an overview of the coupler buffer device, and the analysis is carried out on the types and characteristics of the coupler buffer device. Secondly, the technical characteristics of the current classic coupler buffer device are analyzed, and their common faults are analyzed on this basis. Reason analysis, and then expand the treatment methods for common failures.

The hook buffer device is one of the most basic and important components of the vehicle, so it is necessary to design and build a high-performance, fully functional hook buffer maintenance process line to meet the requirements of the hook buffering device maintenance process. By adopting research methods such as field research method, literature research method and exploratory research method, this paper combines theoretical knowledge research with equipment application research, consults literature, makes in-depth study and analyzes scientific rational practice, and clearly optimizes the idea. This paper briefly introduces the development of hook buffer device, summarizes the rule of experience, and puts forward some suggestions for the future development direction. In this paper, first of all, the overview of the hook buffer device, respectively, to the type and characteristics of the hook buffer device analysis, followed by the current classic hook buffering device for the technical characteristics of the analysis, on the basis of their common faults to analyze the cause, and then expand the treatment of common faults.

Coupler buffer device is one of the most basic and important parts of vehicle. Therefore, it is necessary to design and build a coupler buffer device maintenance process line with excellent performance and complete functions to meet the requirements of coupler buffer device maintenance process. In this paper, through the field research method, literature research method, exploratory research method and other research methods, the implementation of theoretical knowledge research and equipment use research combined, access to literature, in-depth research and analysis, scientific and reasonable policy, clear optimization ideas. This paper briefly introduces the development of coupler buffer device, summarizes the experience and rules, and puts forward some suggestions for the future development direction. In this paper, the first is an overview of the coupler buffer device, respectively to analyze the types and characteristics of the coupler buffer device, followed by the analysis of the technical characteristics of the current classic coupler buffer device, on this basis, the causes of their common faults are analyzed, and then the treatment methods of common faults are carried out.<br>
