The invention discloses a tapered wedge type combined shock absorber and a railway wagon bogie. The shock absorber comprises an inclined wedge body and a main friction plate, the inclined wedge body comprises an inclined wedge body slope, an inclined wedge body vertical face and an inclined wedge body bottom face, and the inclined wedge body slope, the inclined wedge body vertical face and the inclined wedge body bottom face define the inclined wedge body. The inclined surface of the inclined wedge body is arranged to be attached to the end part of a swing bolster of the bogie; the inclined surface of the inclined wedge body is of a double-inclined-surface structure and is provided with a first inclined surface, a second inclined surface and a connecting surface, the included angle betweenthe first inclined surface and the second inclined surface is an obtuse angle, and the connecting surface connects the first inclined surface and the second inclined surface; one side of the main friction plate is detachably connected to the vertical face of the inclined wedge body, and the other side of the main friction plate is arranged to be capable of being attached to a wearing plate on theside frame stand column, and the bottom surface of the inclined wedge body is arranged to be detachably connected to the upper part of a bogie spring of the bogie. According to the inclined wedge body combined shock absorber, the rhombus deformation resistance is improved.
本发明公开了一种斜楔式组合减震器及铁路货车转向架。该减震器包括斜楔体和主摩擦板;所述斜楔体包括斜楔体斜面、斜楔体立面和斜楔体底面,斜楔体斜面、斜楔体立面和斜楔体底面围合成所述斜楔体;所述斜楔体斜面设置为能够与转向架的摇枕端部相贴合;所述斜楔体斜面为双斜面结构,其具有第一斜面、第二斜面和连接面,第一斜面和第二斜面之间的夹角为钝角,连接面将第一斜面和第二斜面连接;所述主摩擦板的一侧可拆卸地连接在斜楔体立面上,所述主摩擦板的另一侧设置为能够与侧架立柱上的磨耗板贴合;所述斜楔体底面设置为能够可拆卸地连接于转向架的转向架弹簧上部。本发明的斜楔体组合减震器提高了抗菱形形变能力。
