Description

Technical Field

[0001] This utility model belongs to the field of vehicle parts technology, and in particular relates to a lateral buffer for passenger cars that is easy to maintain. Background Technology

[0002] Lateral buffers are one of the most important components of rail transit vehicles. They are mounted on the vehicle bogies and control the relative displacement between the car body and the bogies. Lateral buffers include mounting plates, rubber stops, connecting plates, and compression stops. The mounting plates and connecting plates are used to connect the car frame and the bogies, respectively. The compression stops use rubber stops to achieve elastic constraints to reduce lateral impact between the wheels and rails and reduce car body vibration.

[0003] Chinese patent application CN222022698U discloses a lateral buffer for a railway vehicle bogie, comprising a base plate and rubber disposed on the outer side of the base plate. A polymer wear-resistant stop is added to the top of the rubber surface at the impact point, and multiple steel sleeves are added to the middle of the inner side of the rubber. Bolts are provided at the bottom of the rubber. This structure, with the polymer wear-resistant stop added to the top of the rubber, avoids direct collision contact between the rubber and the vehicle body, thus extending the service life of the rubber. Simultaneously, the steel sleeves added to the middle of the rubber significantly increase the overall rigidity of the lateral buffer, further extending the service life of the rubber, demonstrating strong practicality. Furthermore, the polymer wear-resistant stop is installed and connected to the rubber via a connecting component, making installation simple and facilitating the removal and replacement of the polymer wear-resistant stop, thus providing convenience and flexibility in use.

[0004] The aforementioned transverse buffer for a railway vehicle bogie has a rubber base plate with a hemispherical structure. A high-polymer wear-resistant stop is mounted on top, and a high-polymer wear-resistant plug is installed inside the stop. The rubber contacts the car body via the stop and plug. The stop and plug are vulnerable parts, with the plug being the most significant wear component, followed by the stop, and then the rubber. The stop and plug are integrally formed by heat fusion. The structure is mounted on rubber, which leads to a problem: when the polymer wear-resistant stop and plug need replacement due to wear, only the entire rubber unit can be replaced, resulting in resource waste. Furthermore, multiple square-shaped steel sleeves are installed inside the rubber, with connecting cylinders at the top. These connecting cylinders are used for assembling and disassembling the bottom screw of the polymer wear-resistant stop. Since rubber is a soft material, it is bonded to the connecting cylinders. However, during the assembly and disassembly of the polymer wear-resistant stop, the connecting cylinders can easily detach from the rubber, causing damage to the lateral buffer and rendering it unusable. To address these issues, we provide a lateral buffer for buses that is easy to maintain. Utility Model Content
