The invention discloses a single-axle bogie frame, a bogie, a railway vehicle and a forming process, the single-axle bogie frame comprises a cross beam and two side beams, and the two side beams and the cross beam form a symmetrical U shape; a traction pull rod seat mounting hole and a mounting seat mounting hole of a brake clamp are formed in the cross beam; the top faces of the connecting positions of the two side beams and the cross beam are each provided with a damping supporting part of a secondary suspension. The top faces of the non-connecting ends of the two side beams are each provided with a spring supporting part of a secondary suspension, and the bottom face of each cross beam is provided with a mounting hole of an axle box rotating arm, a mounting hole of a primary suspension vertical damping damper and a mounting hole of a primary spring. Compared with an existing single-axle bogie frame, the weight is reduced, and the cost is reduced.
本发明公开了一种单轴转向架构架、转向架、轨道车辆及成型工艺,单轴转向架构架包括一个横梁和两个侧梁,两个侧梁与横梁组成对称的U型;在横梁上开设有牵引拉杆座安装孔和制动夹钳的安装座安装孔;在两个侧梁与横梁的连接位置顶面各设有二系悬挂的阻尼支承部;在两个侧梁的非连接端顶面各设置一个二系悬挂的弹簧支承部,在每个横梁的底面设有轴箱转臂的安装孔、一系悬挂垂向减震阻尼的安装孔和一系弹簧的安装孔。该装置相对于现有的单轴转向架构架,重量降低,成本下降。
