Traction buffer device for locomotive

Abstract

The invention provides a traction buffer device for a locomotive. The traction buffer device comprises a hook tail pin (1), a hook tail frame (2), a central wedge block (3), a rear slave plate (4), abuffer box (5), a buffer plug (6) and an elastic cement gum core body (7) and is characterized in that the front end of the hook tail frame (2) is connected with the hook tail pin (1), and the middleof the hook tail frame (2) is fixedly provided with the buffer box (5) through the buffer plug (6); the central wedge block (3) is arranged at the rear end of the buffer box (5), and the rear slave plate (4) is arranged at the rear end of the central wedge block (3); and the elastic cement gum core body (7) is arranged in the buffer box (5). By means of the design of a nonlinear damping characteristic structure of the elastic cement gum core body, so that the traction buffer device for the locomotive can obtain a good buffer characteristic, through an integrated structure of the buffer box anda front slave plate, the difficult problem of limitation of an installation space of a bottom frame of a locomotive body is solved, and the integrally-forged buffer plug improves centering resettingcapacity of hooks.

Description

technical field [0001] The invention relates to the field of railway safety, in particular to a traction buffer device for locomotives. Background technique [0002] The traction buffer device of railway locomotive is mainly composed of buffer device, coupler and coupler frame and other components. The buffer device is the core component, which is arranged between the locomotive and the locomotive, or between the locomotive and the locomotive. During train operation, the traction buffer device is used to transmit the locomotive traction force and the impact force during braking and coupling. By absorbing or reducing the longitudinal force generated by the locomotive during braking, acceleration, etc. The resulting coupler lateral force and vehicle derailment coefficient can improve the longitudinal dynamic performance of the train and prolong the life of the car body, thereby improving the stability and smoothness of the train operation and ensuring the safety of railway tra...

Problems solved by technology

At the same time, the maintenance cost of the buffer device is high, and the elastomer buffer cake is often damaged after running 80,000 to 100,000 kilometers, and the entire hook buffer device needs to be replaced every year
