The wedge friction damping device comprises a wedge body, the wedge body is provided with a main friction surface, a plurality of mounting holes are formed in the main friction surface, lubricating bodies are mounted in the mounting holes, and the main friction surface is provided with a plurality of friction surfaces; the lubricating body protrudes out of the surface of the main friction face by 0-1 mm. According to the wedge friction damping device for the bogie of the railway wagon, the structure of an existing wedge friction damping device for the bogie is effectively simplified, noise and clamping stagnation of abrasion between metal are reduced, and the wedge friction damping device is convenient to overhaul and maintain, high in practicability and long in service life.

    本发明公开了一种铁路货车转向架用斜楔摩擦减振装置及铁路货车转向架、铁路货车,该斜楔摩擦减振装置包括斜楔体,所述斜楔体具有主摩擦面,所述主摩擦面上开设有若干个安装孔,所述安装孔内安装有润滑体,所述润滑体凸出主摩擦面的表面0‑1mm。本发明的铁路货车转向架用斜楔摩擦减振装置有效简化了既有转向架斜楔摩擦减振装置结构,降低了金属之间对磨的噪音和卡滞特性,而且检修维护方便、实用性强、使用寿命长。
