Description

Technical Field

[0001] This utility model belongs to the field of buffer technology, and more specifically, it relates to a limiting wear-resistant lateral buffer. Background Technology

[0002] In the field of railway vehicle operation, in order to ensure the stable operation of the car body and bogie when the vehicle passes through curves and reduce the safety hazards caused by lateral displacement, technicians often install lateral buffers between the car body and the bogie.

[0003] However, traditional devices lack convenient installation capabilities, leading to significantly reduced installation efficiency due to complex structures and cumbersome operations. Since railway vehicle maintenance and repair are typically time-sensitive, this complex installation process forces maintenance personnel to spend considerable time and effort installing and replacing lateral buffers, potentially extending railway vehicle downtime. This not only disrupts normal railway transport operations and reduces efficiency but also increases operating costs due to prolonged downtime, ultimately hindering the development of the railway transport industry. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a limiting and wear-resistant lateral buffer to solve the technical problem that traditional devices in the prior art do not have convenient installation functions.

[0005] The purpose and effect of this utility model of a limiting wear-resistant lateral buffer are achieved by the following specific technical means: A limiting wear-resistant lateral buffer includes a low plate and a buffer rubber. The low plate and the buffer rubber are integrally formed. A circumferential limiting cylinder is provided on the outer side of the buffer rubber. The circumferential limiting cylinder is fitted with the outer wall of the buffer rubber to limit the shear displacement of the lateral buffer. A nylon wear plate is provided at the end of the circumferential limiting cylinder away from the low plate. The nylon wear plate is fixedly connected to the end face of the circumferential limiting cylinder away from the low plate to improve the friction when the lateral buffer contacts the frame. The low plate and the circumferential limiting cylinder are welded to form a base. The base is used to install and fix the lateral buffer, and the lateral buffer is mounted on the vehicle body traction pin seat through the base to suppress the lateral displacement of the vehicle body bogie when the vehicle passes through a curve.

[0006] According to a preferred embodiment, the nylon wear plate is made of nylon material, and the nylon wear plate forms a contact plane with the contact end face of the frame to ensure that the friction force is matched when in contact with the frame.

[0007] According to a preferred embodiment, the circumferential limiting cylinder is annular, the inner wall of the circumferential limiting cylinder is in contact with the outer wall of the buffer rubber, and the axis of the circumferential limiting cylinder is collinear with the axis of the buffer rubber.

[0008] According to a preferred embodiment, the low plate is flat and has mounting holes for connecting with the vehicle body traction pin seat. The mounting holes are evenly distributed around the circumference of the low plate, and the lateral buffer is fixedly installed with the vehicle body traction pin seat by bolts.

[0009] According to a preferred embodiment, the buffer rubber, the circumferential limiting cylinder, and the nylon wear plate form a buffer limiting unit. The number of buffer limiting units is one set, and the buffer limiting unit is coaxially arranged in the middle of the low plate to achieve lateral buffering and limiting.

[0010] According to a preferred embodiment, the low plate and the circumferential limiting cylinder are connected by a continuous weld at the welding point, and the weld is arranged circumferentially along the bottom of the circumferential limiting cylinder, so that the low plate and the circumferential limiting cylinder are connected.

[0011] According to a preferred embodiment, the lateral buffer is installed after the vehicle body traction pin seat to form a gap between itself and the frame, and the gap is adapted to the steering angle of the vehicle body bogie when the vehicle is running in a straight line.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This device, through the use of a circumferential limiting cylinder and a nylon wear plate, can limit the shear displacement of the lateral buffer and improve the friction condition when in contact with the frame, thereby enhancing the stability and durability of the device. The device can limit the shear displacement of the buffer during operation by having the circumferential limiting cylinder adhere to the outer wall of the buffer rubber, improving the reliability of the device when subjected to lateral forces.

[0013] 2. When using this device, it can be easily installed by bolting to the vehicle body traction pin seat through the evenly distributed mounting holes on the low plate, allowing it to be mounted on the vehicle body and improving installation convenience. Then, a buffer limiting unit, formed by the buffer rubber, circumferential limiting cylinder, and nylon wear plate, is coaxially mounted in the center of the low plate.

[0016] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0017] Example: For example Figures 1 to 2 As shown, this utility model provides a limiting wear-resistant lateral buffer, including a low plate 11 and a buffer rubber 12. The low plate 11 and the buffer rubber 12 are integrally formed. A circumferential limiting cylinder is provided on the outer side of the buffer rubber 12. The circumferential limiting cylinder is attached to the outer wall of the buffer rubber 12 to limit the shear displacement of the lateral buffer. A nylon wear plate 13 is provided at the end of the circumferential limiting cylinder away from the low plate 11. The nylon wear plate 13 is fixedly connected to the end face of the circumferential limiting cylinder away from the low plate 11 to improve the friction when the lateral buffer contacts the frame. The low plate 11 and the circumferential limiting cylinder are welded to form a base 14. The base 14 is used to realize the installation and fixation of the lateral buffer. The lateral buffer is installed on the vehicle body traction pin seat through the base 14 to suppress the lateral displacement of the vehicle body bogie when the vehicle passes through a curve.

[0018] Specifically, the low plate 11 provides a supporting foundation for the entire lateral buffer and is integrally formed with the buffer rubber 12 to enhance connection stability. The buffer rubber 12 is a buffering functional component that elastically deforms to buffer lateral forces. The circumferential limiting cylinder wraps around the outside of the buffer rubber 12 and fits against the outer wall of the buffer rubber 12 to limit its shear displacement, ensuring that the buffer rubber 12 operates within a certain range and improving the reliability of the lateral buffer.

[0019] The nylon wear plate 13 is made of nylon material. The nylon wear plate 13 forms a plane with the contact end face of the frame to ensure that the friction force is appropriate when in contact with the frame.

[0020] Specifically, the nylon material gives the nylon wear plate 13 wear resistance and self-lubrication, and a thick wear-resistant layer is added to the nylon wear plate 13. The flat surface setting that contacts the frame ensures that the friction force is uniform and appropriate when in contact, so that it does not affect the bogie movement too much, nor cause the buffer to shift and wobble too little, thereby improving the friction condition between the lateral buffer and the frame and extending the service life of the buffer.

[0021] The circumferential limiting cylinder is annular, with its inner wall fitting against the outer wall of the buffer rubber 12, and the axis of the circumferential limiting cylinder being collinear with the axis of the buffer rubber 12.

[0022] Specifically, the inner wall of the annular circumferential limiting cylinder is attached to the outer wall of the buffer rubber 12, providing lateral support for the buffer rubber 12. The circumferential limiting cylinder and the axis of the buffer rubber 12 are collinear, so that when the buffer rubber 12 is subjected to lateral force, the force is evenly transmitted to the circumferential limiting cylinder, avoiding large local stress, improving the buffering effect and service life of the buffer rubber 12, and ensuring the stable operation of the buffer.

[0023] like Figures 1 to 4 As shown, the low plate 11 is flat and has mounting holes for connecting with the vehicle body traction pin seat. The mounting holes are evenly distributed around the circumference of the low plate 11, and the lateral buffer is fixedly installed with the vehicle body traction pin seat by bolts.

[0024] Specifically, the flat, low-profile plate 11 is easy to machine and connect to the vehicle body traction pin seat. The circumferentially evenly distributed mounting holes are connected to the screw holes of the vehicle body traction pin seat via bolts, thus fixing the lateral buffer to the vehicle body traction pin seat. The evenly distributed mounting holes ensure that the buffer evenly bears the force of the vehicle body after installation, guaranteeing stable operation of the buffer.

[0025] The buffer rubber 12, together with the circumferential limiting cylinder and the nylon wear plate 13, forms a buffer limiting unit. The number of buffer limiting units is one set, and the buffer limiting units are coaxially arranged in the middle of the low plate 11 to achieve lateral buffering and limiting.

[0026] Specifically, the buffer rubber 12, the circumferential limiting cylinder, and the nylon wear plate 13 constitute a buffer limiting unit, coaxially arranged in the middle of the low plate 11. This layout allows the buffer limiting unit to concentrate on dealing with the lateral forces of the vehicle when crossing curves, achieving lateral buffering and limiting. The coaxial arrangement ensures direct and efficient force transmission, avoiding force transmission deviations that could affect the buffering effect or damage components, and ensuring stable operation of the vehicle bogie when crossing curves.

[0027] The low plate 11 and the circumferential limiting cylinder are connected by a continuous weld. The weld is set along the bottom circumferential direction of the circumferential limiting cylinder, so that the low plate 11 and the circumferential limiting cylinder are connected.

[0028] Specifically, the connection between the low plate 11 and the circumferential limiting cylinder adopts a continuous weld along the bottom circumferential direction of the circumferential limiting cylinder. The continuous weld has high connection strength, ensuring that the low plate 11 and the circumferential limiting cylinder will not loosen or separate under the long-term force of vehicle operation. The continuous circumferential weld ensures uniform connection and the same connection strength in all directions, thereby enhancing the structural stability of the lateral buffer.

[0029] The lateral buffer is installed behind the traction pin seat of the car body to form a gap between itself and the frame. The gap is adapted to the steering angle of the car body bogie when the vehicle is running in a straight line.

[0030] Specifically, the lateral buffer is mounted on the car body traction pin seat via base 14, creating a gap between itself and the frame. This gap is set according to the steering angle of the bogie when the vehicle is traveling straight. When the vehicle is traveling straight, the gap provides the bogie with room to maneuver, allowing it to adjust its direction with slight changes in the track, and preventing instability caused by a large gap. When the vehicle is crossing a curve, the buffer uses the buffer rubber 12 and the circumferential limit cylinder to suppress the lateral displacement of the bogie, ensuring the vehicle passes through the curve safely and smoothly.

[0031] The specific usage and function of this embodiment are as follows: In use, the wear-resistant lateral buffer is fixed to the car body traction pin seat with bolts through the mounting holes of the low plate 11 on the base 14. When the vehicle is running in a straight line, the gap between the lateral buffer and the frame provides the bogie with room to move, allowing it to adjust its direction according to slight changes in the track and ensuring stable operation.

[0032] When the vehicle passes through a curve and generates lateral force, the buffer rubber 12 undergoes elastic deformation to buffer the force, while the circumferential limiting cylinder restricts its shear displacement, ensuring that the buffer rubber 12 operates within its range and simultaneously distributing the force evenly to avoid excessive local stress. The nylon wear plate 13, with its nylon material and thick wear-resistant layer, ensures appropriate friction on the plane in contact with the frame, improving the friction condition in contact with the frame and preventing the buffer from shifting or swaying.

[0033] The buffer limiting unit, consisting of buffer rubber 12, circumferential limiting cylinder and nylon wear plate 13, is coaxially set in the middle of the low plate 11. It concentrates on dealing with lateral force and transmitting force, suppressing the lateral displacement of the bogie, and ensuring the stable operation of the bogie when the vehicle passes through curves. The entire lateral buffer relies on the coordinated action of each component to improve the safety and stability of vehicle operation.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
