[0002] With the rapid development of high-speed trains such as EMUs and subways in China, tight couplings have been widely used in these high-speed trains due to their excellent performance. Compared with traditional couplings, tight couplings exhibit significant advantages in meeting the high-standard requirements of high-speed trains on running safety, passenger comfort and driving stability. In the installation process, not only must the horizontal and vertical positioning of the coupling and the passenger car body be extremely accurate, but also the mutual connection between couplings is set with strict accuracy standards.

[0022] The present application will be described in detail below with reference to the embodiments, but the present application is not limited to these embodiments.

[0023] Reference Figs. 1-3 A centering and hanging device for a tight coupling, suspended on a car coupler buffer 1, the tight coupling 2 connected with the car coupler buffer 1, comprising:

[0024] A centering beam 3, both ends of the centering beam 3 are provided with a hanger rod 4, for forming a buffer in the horizontal direction of the tight coupling 2, one end of the hanger rod 4 is hinged with the centering beam 3, the other end of the hanger rod 4 is suspended on the car coupler buffer 1, a hanging space is formed between the centering beam 3, the car coupler buffer 1 and the hanger rod 4, and the tight coupling 2 is located in the hanging space;

[0025] The centering beam 3 is provided with a mounting groove 5, the tight coupling 2 is located in the mounting groove 5, and the centering beam 3 is further provided with a buffer assembly, the buffer assembly is located in the mounting groove 5, for forming a buffer in the vertical direction of the tight coupling 2.

[0026] Specifically, one end of the hanger rod is hinged with the centering beam, and the other end is suspended on the car coupler buffer, so that the hanger rod can provide effective buffer in the horizontal direction. When the train runs on uneven road surface or encounters emergency braking, etc., the hinged design of the hanger rod can absorb and disperse the impact force in the horizontal direction, protecting the coupler and connecting parts from damage. The centering beam is specially provided with a mounting groove for accommodating the tight coupling, and a buffer assembly is built-in to provide buffer in the vertical direction. This design not only ensures the stability of the coupler in the vertical direction, but also effectively reduces the vibration and noise caused by the up and down of the train, improving the riding comfort of passengers. Combined with the horizontal buffer of the hanger rod and the vertical buffer of the buffer assembly, the train coupler system is provided with all-round protection. Whether it is horizontal or vertical impact force, it can be effectively absorbed and dispersed by the device, ensuring the safety and stability of train operation.

[0027] It is worth noting that the tight coupling and the car coupler buffer in the present application are both existing devices, and the centering and hanging device can be suspended on the car coupler buffer to realize the centering and hanging function.

[0028] A plurality of mounting holes 6 are uniformly arranged in the length direction of the centering beam 3, which are arranged vertically through the centering beam 3 and located on the mounting groove 5, and the buffer assembly is mounted in the mounting hole 6.

[0029] Specifically, in the coupling device of the tight coupling, the centering beam serves as the core component, not only bearing the weight of the coupler, but also achieving the buffering and centering functions of the coupler in the horizontal and vertical directions through its unique design. A plurality of mounting holes 6 are uniformly arranged in the length direction of the centering beam 3, so that the buffer assembly can be accurately mounted on the centering beam, ensuring that the coupler obtains stable buffering effect in the vertical direction. The uniform distribution of the mounting holes not only ensures the balanced stress of the buffer assembly on the centering beam, but also provides great flexibility for installation and adjustment. According to actual needs, different numbers of mounting holes can be selected to install the buffer assembly to adapt to the needs of different vehicle models and operating conditions. By mounting the buffer assembly in the mounting hole, the centering beam can more effectively absorb and disperse the impact force of the coupler in the vertical direction. This not only protects the coupler and connecting components from damage, but also significantly improves the smoothness and safety of train operation.

[0030] The buffer assembly includes an abrasion base 7, and an abrasion plate 8 is arranged on the abrasion base 7, and the tight coupling 2 is located above the abrasion plate 8.

[0031] A plurality of limiting bolts 9 corresponding to the mounting holes 6 are arranged below the abrasion base 7, the limiting bolts 9 are externally sleeved with springs 10, the limiting bolts 9 pass through the mounting holes 6, and the springs 10 are clamped above the mounting holes 6.

[0032] Specifically, the abrasion base 7 is the basic component of the buffer assembly, which is usually made of wear-resistant materials to ensure that it can withstand the friction and wear of the coupler and connecting components during long-term use. The abrasion plate 8 is mounted on the abrasion base and directly contacts the tight coupling. Its main function is to reduce the friction between the coupler and the buffer assembly, prolonging the service life of the entire device. The limiting bolt 9 is a key component connecting the abrasion base and the centering beam. It passes through the mounting hole to fix the abrasion base on the centering beam, and realizes the buffering effect through the compression and release of the spring. The spring 10 is externally sleeved on the limiting bolt and clamped above the mounting hole. When the coupler is subjected to external force, the spring can absorb and disperse the impact force, protecting the coupler and connecting components from damage.

[0033] The mounting groove 5 includes a primary mounting groove and a secondary mounting groove arranged vertically along the centering beam 3 from top to bottom, the width of the primary mounting groove is greater than that of the secondary mounting groove, thereby forming a lap platform 11, and the abrasion base 7 is lapped on the lap platform 11.

[0034] The mounting hole 6 is located in the secondary mounting groove.

[0035] Specifically, the mounting groove on the centering beam is ingeniously designed as two parts, a primary mounting groove and a secondary mounting groove. The width of the primary mounting groove is greater than that of the secondary mounting groove, thereby forming an overlapping platform between the two. This design not only increases the flexibility of the mounting groove, but also provides more stable support for the installation of the wear base. The overlapping platform is formed by the difference in width between the primary mounting groove and the secondary mounting groove. The wear base is designed to overlap on this platform, which not only ensures the stable installation of the wear base, but also enhances the overall stability of the buffer assembly through the support of the platform.

[0036] The mounting groove 5 is located in the middle of the centering beam 3, and the two ends or the ring of the secondary mounting groove form an overlapping platform 11.

[0037] Specifically, the mounting groove is carefully arranged in the middle of the centering beam, which helps to ensure that the coupler obtains uniform support and buffering effect in the horizontal direction. At the same time, the middle position also facilitates the installation and maintenance work. At the two ends or the ring of the secondary mounting groove, an overlapping platform is ingeniously formed. The design of this platform not only increases the flexibility and practicality of the mounting groove, but also provides more stable support for the wear base. When the two ends of the secondary mounting groove form an overlapping platform, the wear base can be more closely fitted on the platform, ensuring the stability of the buffer assembly in the horizontal direction. It is suitable for application scenarios that require higher lateral stability. In some cases, in order to further enhance the support effect of the buffer assembly, the secondary mounting groove can be designed to form an overlapping platform in a ring shape. In this way, the wear base will be able to fit on the platform in all directions, achieving more stable installation. It is worth noting that when it is a ring-shaped overlapping platform, the secondary mounting groove is embedded, and its length and width are smaller than those of the primary mounting groove.

[0038] One end of the boom 4 is connected to the centering beam 3 through a pin shaft 12.

[0039] Specifically, after the boom is connected to the centering beam through the pin shaft, an effective support structure can be formed to bear the weight of the coupler and the connecting components. At the same time, during the train running process, the boom can also play a buffering role to absorb and disperse the impact force from the road, protecting the coupler and the connecting components from damage.

[0040] Centering and guiding: the connection of the boom and the centering beam also has certain centering function. When the coupler is subjected to external force, the boom can achieve a certain degree of deflection and recovery through the pin shaft, thereby maintaining the stability of the coupler on the longitudinal centerline position. In addition, the boom can also play a guiding role in the process of coupling and uncoupling the coupler, ensuring that the coupler can accurately and quickly realize coupling and uncoupling.

[0041] It is worth mentioning that the present application fully considers various force conditions in the process of train operation, and realizes the automatic centering and buffering function of the coupler in the horizontal and vertical directions. When there is no external force: the coupler tail is placed on the wear plate of the centering hanging device, and due to the gravity of the coupler itself, the hanger rod will be pulled tight. At this time, the part where the hanger rod is hinged with the centering beam will automatically return to the middle position by gravity, ensuring that the coupler is in the correct centering state. When there is external force: vertical direction: when external force acts on the coupler, the vertical component of force will be transmitted to the centering beam through the compression of the spring. The centering beam transmits the force to the two hanger rods through the pin shaft, and the hanger rods transmit the force to the coupler buffer, and finally the car body bears it. In this process, the spring not only plays a role in transmitting force, but also has a certain buffering effect. Through the design of the limiting bolt, the coupler can complete a ±7° swing action in the vertical direction to adapt to the fluctuation of the train in the vertical direction. Horizontal direction: the horizontal component of external force is first offset by the friction between the coupler tail and the wear plate. When the coupler tail leans on one side of the lower part of the centering beam, the centering beam will complete a ±30° swing action with the help of the pin shaft. In this process, the gravity of the coupler will also play a certain buffering effect, further reducing the influence of external force on the train system. When the external force disappears: under the action of the gravity of the coupler itself, the coupler as a whole will quickly return to the middle position when there is no external force, ensuring the stability and safety of the train system.

Although the above preferred embodiments are disclosed, they are not intended to limit the present application.
