The invention discloses a railway wagon swing bolster assembly. A lower center plate, a side bearing and a backstop are arranged on the swing bolster; the lower center plate of the swing bolster, the side bearing wearing plate mounting surface and the stop hole are prefabricated through integral casting; a sand and dust protection ring mounting groove with a U-shaped groove structure is formed in an upper opening of the lower center plate; a sand and dust protection ring made of an elastic material is embedded and fixed in the sand and dust protection ring mounting groove; when the upper center plate and the lower center plate of the bogie are combined, the bottom surface is in elastic closed contact with the dust protection ring; the side bearing wearing plate is fixed on the side bearing wearing plate mounting surface through welding; the backstops are fixedly installed on the upper planes of the two ends of the swing bolster through the backstop holes. According to the swing bolster, the center plate is designed in a sealed mode, vertical gaps between the side frame upper chord and the upper planes at the two ends of the swing bolster are limited, the structure of the swing bolster is improved, sand and dust are prevented from being accumulated in an inner cavity, and the swing bolster assembly has the whole vehicle hoisting function by improving the structure of the center pin. Railway vehicle operation risks are further reduced, abrasion is reduced, and the railway wagon operation performance is improved.

    本发明公开了一种铁路货车摇枕组成。包括:摇枕上设置下心盘、旁承和止挡;摇枕的下心盘、旁承磨耗板安装面、止挡孔通过整体铸造预制设置;下心盘上口设置U形槽结构的沙尘防护圈安装槽,由弹性材料制成的沙尘防护圈嵌入固定于沙尘防护圈安装槽中;转向架的上心盘与下心盘结合时、底面与沙尘防护圈弹性封闭接触;旁承磨耗板通过焊接固定在旁承磨耗板安装面上;止挡通过止挡孔安装固定在摇枕两端部上平面。本发明摇枕通过对心盘进行密封设计,限制侧架上弦杆与摇枕两端上平面的垂向间隙,改进摇枕结构避免沙尘在内腔堆积,通过改进中心销结构使摇枕组成具有整车起吊功能。本发明进一步降低铁路车辆运行风险、减少磨损,提高铁路货车运行性能。
