答案

参考答案:

组装顺序及要求如下:将构架翻转倒置使轴箱弹簧支承面朝上;将轴箱弹簧预先用弹簧夹板与工艺螺栓使弹簧压缩至(262±2)mm,并置于构架的支承座内:将弹性定位套用工装预压缩,并利用夹紧箍装于定位转臂的定位端连成整体,安装前应在各连接面涂以清漆;将弹簧缓冲垫置于轴箱弹簧上后,将定位转臂一端放在弹簧缓冲缓垫上,另一端与构架定位臂座组装连接;测量组装后的定位转臂尺寸:要求各定位转臂上之定位销的纵向间距(2180±1)mm之差小lmm。

横向间距(1956±1)mm之差小于1mm,其对角线之差小于2mm;安装轮对提吊,并检查各轴箱弹簧是否正位,与弹簧座是否相碰;将构架翻转正位落于四支点组装台上,依次组装基础制动各件、中央悬挂各件以及扭杆装置,扭杆装置的连杆组成应事先与摇枕连成一体,组装各盘形制动缸应使进气嘴朝上,踏面制动缸进气嘴朝内水平方向;转向架落轮对,使定位转臂上的定位销落入轴箱体承载座上的定位孔内;测量并调整两侧固定轴距之差不大于1.5mm后,将轮对与定位转臂紧固在一起。
