At this time, the first sealing ring 801 and the second sealing ring 803 will seal the rotating connection between the mounting rod 3 and the mounting ring 4 in a space, thereby achieving the effect of facilitating the sealing of the rotating connection between the mounting rod 3 and the mounting ring 4.

[0032] In this embodiment: by injecting lubricating oil into the first lubricating oil channel 5 and then discharging it into the space sealed by the first sealing ring 801 and the second sealing ring 803 through the second lubricating oil channel 7 connected to the first lubricating oil channel 5, the rotating connection between the mounting rod 3 and the mounting ring 4 can be lubricated, thereby achieving the effect of facilitating the addition of lubricating oil to the rotating connection between the mounting rod 3 and the mounting ring 4.

[0033] As a technical optimization solution of the utility model, a sealing cover 6 is provided on the top of the first lubricating oil channel 5 , and the surface of the sealing cover 6 is threadedly connected to the inner wall of the first lubricating oil channel 5 .

[0034] In this embodiment, the sealing cover 6 is connected to the inner thread of the first lubricating oil passage 5 , so that the sealing cover 6 can seal the first lubricating oil passage 5 , thereby achieving the effect of sealing the first lubricating oil passage 5 .

[0035] As a technical optimization solution of the utility model, the front and rear sides and the top of the two protective covers 2 are fixedly connected with fixed blocks 10, and a screw 9 is provided on the right side of the right fixed block 10. The side of the screw 9 close to the right fixed block 10 passes through the right fixed block 10 and is connected to the internal thread of the left fixed block 10.

[0036] In this embodiment, by passing the screw 9 through the right fixing block 10 and connecting with the internal thread of the left fixing block 10 , the two protective sleeves 2 can be connected together, thereby achieving the effect of connecting the two protective sleeves 2 .

[0037] As a technical optimization solution of the present utility model, the protective sleeve 2 is made of a lightweight, corrosion-resistant metal, and the first sealing ring 801 and the second sealing ring 803 are both made of polyurethane.

[0038] In this embodiment: Since the first sealing ring 801 and the second sealing ring 803 are both made of polyurethane, polyurethane has excellent wear resistance, oil resistance and shear resistance, which can extend the service life of the first sealing ring 801 and the second sealing ring 803. Since the protective sleeve 2 is made of lightweight and corrosion-resistant metal, the weight of the protective sleeve 2 can be reduced while extending the service life of the protective sleeve 2, thereby achieving the effect of extending the service life of the protective sleeve 2, the first sealing ring 801 and the second sealing ring 803.

[0039] Working principle: First, the external adaptive vibration reduction system is connected to the train wheel-rail vibration damper body 1. The external adaptive vibration reduction system consists of a sensor, a controller and a vibration reduction actuator. The sensor is used to monitor the running status of the train, the vibration of the train wheels and tracks and other related parameters. The controller calculates the vibration reduction parameters that need to be adjusted based on the data collected by the sensor through certain algorithms and strategies, and sends a control signal to the vibration reduction actuator. The vibration reduction actuator adjusts the stiffness, damping or other parameters of the vibration reduction device according to the instructions of the controller to achieve the best vibration reduction effect. Before installing the train wheel-rail vibration damper body 1, pass the mounting rod 3 through the mounting ring 4, and then put the protective cover 2 on the surface of the mounting rod 3 so that the mounting rod 3 Pass through the second sealing ring 803, move the protective sleeve 2 until the surface of the protective sleeve 2 contacts the surface of the mounting ring 4, and then the first sealing ring 801 can seal the protective sleeve 2 and the mounting rod 3. After the two protective sleeves 2 are both sleeved on the surface of the mounting ring 4, pass the screw 9 through the right fixing block 10 and connect it with the internal thread of the left fixing block 10. At this time, the two protective sleeves 2 can be connected together. At this time, the side of the first sealing ring 801 close to the mounting ring 4 will be in close contact with the surface of the mounting ring 4. At this time, the first sealing ring 801 and the second sealing ring 803 will seal the rotating connection between the mounting rod 3 and the mounting ring 4 in a space, and then the external bolts can be used to pass through the mounting rod 3 and threadedly connect it to the train body to install the train wheel-rail damper The main body 1 is installed. During the use of the train wheel-rail shock absorber main body 1, external dust can be prevented from invading the rotating connection between the mounting rod 3 and the mounting ring 4, thereby preventing accelerated wear of the mounting rod 3 and the mounting ring 4, and avoiding the problem that most existing train shock absorbers do not have the function of adaptive adjustment. After the train shock absorber is installed, the rotating connection between the mounting rod 3 and the train shock absorber mounting ring 4 does not have a dustproof structure, and dust can easily invade between the mounting rod 3 and the shock absorber mounting ring 4, accelerating wear and affecting the service life of the train shock absorber. Since the first sealing ring 801 and the second sealing ring 803 are both made of polyurethane material, polyurethane has excellent wear resistance, oil resistance and shear resistance, which can extend the service life of the first sealing ring 801 and the second sealing ring. 803. Since the protective sleeve 2 is made of lightweight and corrosion-resistant metal, the weight of the protective sleeve 2 can be reduced while the service life of the protective sleeve 2 can be extended. When it is necessary to lubricate the rotating connection between the mounting rod 3 and the mounting ring 4, the sealing cover 6 is rotated to disengage the threaded connection between the sealing cover 6 and the interior of the first lubricating oil channel 5, and the lubricating oil can be injected into the first lubricating oil channel 5, and then discharged to the space sealed by the first sealing ring 801 and the second sealing ring 803 through the second lubricating oil channel 7 connected to the first lubricating oil channel 5, so as to lubricate the rotating connection between the mounting rod 3 and the mounting ring 4. It should be noted that the adaptive vibration damping system is an existing mature technology that has been published and is often used in today's high-end automobile suspensions, which will not be elaborated here.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
