The invention discloses a vehicle body and bogie connecting device structure suitable for passing through a minimum radius curve, the vehicle body and bogie connecting device structure comprises a bogie frame, a connecting device and a vehicle body, the bogie frame is connected with the lower end of the connecting device, and the upper end of the connecting device is connected with the lower end of the vehicle body. The connecting device and a bogie frame are designed in degree of freedom, limited x-axis (longitudinal) and z-axis rotation degree of freedom and z-axis (vertical) and y-axis (transverse) rotation degree of freedom around x-axis and y-axis rotation degree of freedom are released, the motion displacement is determined by an air spring and a transverse stopper, the connecting device and a vehicle body are designed in degree of freedom, x, y and z translation and rotation degree of freedom around x and y are restrained, the rotation degree of freedom around z-axis is released, and the motion displacement is determined by an air spring and a transverse stopper. The connecting part does not rotate, the requirement for rotation displacement does not exist, the problem of part displacement passing through a minimum radius curve is solved, and on the basis that the rigidity of the rib plate is not reduced, the maximum stress is transferred to the rib plate base material position from a welding seam.

    本发明公开了一种适用于通过极小半径曲线的车体与转向架连接装置结构,包括转向架构架、连接装置和车体,所述转向架构架与连接装置的下端连接,所述连接装置的上端与车体的下端连接。本发明连接装置与转向架构架自由度设计,限制的x向(纵)及绕z轴回转自由度,z向(垂)、y向(横)、绕x轴回转绕y轴回转自由度释放,其运动位移由空簧和横向止挡决定,连接装置与车体自由度设计,约束x、y、z平动及绕x和y的转动自由度,释放绕z轴的回转自由度,连接部件不发生回转,没有回转位移要求,解决了通过极小半径曲线的零部件变位问题,并且在不降低筋板刚度的基础上,将最大应力从焊缝转移至筋板母材位置。
