The invention relates to a buffer device, in particular to a composite joint installed in a car coupler.

Background

In the manufacturing process of the railway locomotive at present, two adjacent carriages are widely connected by a coupler, and the coupler is used as a key part of the locomotive and has important influence on the dynamic performance and the running quality of the locomotive. Along with the implementation of railway speed-raising and heavy-load strategies, the car coupler has the defects that the car coupler lacks variable rigidity, the fatigue damage of a rubber part affects the running performance of a locomotive, the running stability of the locomotive is poor, and hidden dangers are caused to the running safety.

The existing coupler has rigid connection and poor buffering performance. Some car couplers have a buffering structure, but are single in rigidity adjustment, lack variable rigidity, and are difficult to meet the requirement that the car is started with small rigidity under a large load to have good buffering performance; and the variable rigidity can be generated during emergency braking or turning, so that the rigidity of the car coupler is greatly increased, and the stability of the car is ensured.

The following patents are found to have similarities with the present invention through domestic search: the invention with application number 201510532446.3 and the name 'coupler rear-mounted crushing pipe with a limiting device' relates to a coupler rear-mounted crushing pipe with a limiting device, which comprises a buffer, the crushing pipe and a coupler mounting seat, wherein the crushing pipe comprises a crushing device and an expansion pipe, and the crushing device comprises a pressurizing seat and a pressurizing cone and is positioned at one end of the expansion pipe; one end of the buffer is provided with a joint bearing, and the joint bearing is contacted with the pressurizing seat; the crushing pipe is arranged on the coupler mounting seat, the knuckle bearing is connected with the pressurizing seat through a coupler yoke pin, and a limiting disc is arranged along the circumference of the outer diameter of the shell of the buffer shell; and a limiting table is arranged on one surface of the coupler mounting seat facing the limiting disc. The invention has simple structure, solves the problem that the rear-mounted crushing pipe is difficult to realize the limiting after the working stroke is finished, and when the crushing device is triggered to move, the limiting disc and the limiting table limit the working stroke of the crushing pipe, thereby reducing the impact on the vehicle body. The accurate limitation to the working stroke of the rear-mounted crushing pipe can be realized by adjusting the position of the limiting disc.
