The invention relates to the technical field of railway vehicle underframes, in particular to a railway vehicle large-section traction sleeper buffer underframe structure which comprises a sleeper beam, a traction beam, a car coupler mounting seat and two buffer beams and further comprises two connecting beams, the car coupler mounting seat is fixedly connected with the sleeper beam through the traction beam, and the connecting beams correspond to the buffer beams one to one. The two sets of connecting beams are arranged on the two sides of the traction beam respectively, and each buffer beam is fixedly connected with the sleeper beam through the corresponding connecting beam. Two sets of reinforcing rods are arranged between the two sets of connecting beams, each set of reinforcing rods is connected with the corresponding connecting beam through a connecting unit, and the traction beam is located between the two sets of reinforcing rods. The traction beam has the advantages that the alternating load of the buffer beam is applied to the connecting beam, when the connecting beam is subjected to fatigue fracture, the traction beam can still be connected with the two carriages, and therefore the using safety of the railway vehicle is improved.

    本申请涉及一种轨道车辆大断面牵枕缓底架结构,其涉及轨道车辆底架技术领域,其包括枕梁、牵引梁、车钩安装座以及两组缓冲梁,车钩安装座通过牵引梁与枕梁固定连接,还包括两组连接梁,连接梁与缓冲梁一一对应,两组连接梁分设在牵引梁的两侧,每个缓冲梁均通过连接梁与枕梁固定连接;两组连接梁之间设有两组加强杆,每组加强杆与连接梁之间均通过连接单元连接,牵引梁位于两组加强杆之间。本申请具有将缓冲梁的交变载荷施加到连接梁上,连接梁发生疲劳断裂时,牵引梁仍能连接两个车厢,从而提高轨道车辆使用的安全性的效果。
