The invention provides a guide frame type bogie frame suitable for a rail engineering vehicle, and relates to the technical field of bogie frames, the bogie frame comprises a cross beam and two side beams, the two ends of the cross beam are fixedly connected to the middle positions of the two side beams, and an H-shaped frame structure is formed; every two guide frame sets are arranged at the bottom of one side beam and located at the two ends of the cross beam respectively. The guide frame group comprises two guide frames, the two guide frames are oppositely and fixedly connected to the side beams in the length direction of the side beams, a mounting groove is formed between the opposite faces of the two guide frames, the mounting groove is used for mounting a series of springs and can bear longitudinal and transverse impact force under heavy load, traction force is transmitted to a framework from a wheel set axle box, the stability of traction performance is improved, and the service life of the framework is prolonged. And good stability performance of the vehicle body is kept.
本发明提供一种适用于轨道工程车用导框式转向架构架,涉及转向架构架技术领域,该转向架构架包括:横梁和两侧梁,横梁的两端固接于两侧梁的中部位置,形成H形框架结构;四个导框组,每两个导框组设置于其中一个侧梁的底部且分别位于横梁的两端;导框组包括两导框,两导框沿侧梁的长度方向相对固接于侧梁上,在两导框相对的面之间形成安装槽,安装槽用于安装一系弹簧,在重载下,可以承受纵向及横向的冲击力,并将牵引力从轮对轴箱传递至构架,提高了牵引性能的稳定性,使车体保持良好的稳定性能。
