The invention discloses a high-speed inner axle box bogie of a railway freight car, which is arranged in an inner axle box mode, can effectively reduce the axle distance of the bogie and optimize the stress of a framework by adopting a primary suspension device, can reduce the deflection of a steel spring, and reasonably arranges the proportion of the offset distance of the steel spring to the length of a rotating arm. The damping effect of the damper can be improved; the combined mode that the secondary suspension device, the conical rubber spring and the laminated rubber spring are connected in series is adopted, appropriate vertical suspension rigidity and horizontal shearing rigidity can be provided for a vehicle body and a bogie, the structure is simple, meanwhile, an air spring can be replaced, cost can be reduced on the premise that the requirement for empty and load vehicles is met, and the service life is prolonged. Through the primary suspension mode and the secondary suspension mode of the bogie, the bogie can have a compact structure in the transverse direction and the longitudinal direction, the unsprung mass and the overall bogie mass are reduced to the maximum extent, the light weight purpose can be obviously achieved, and the running stability, stability and running speed of a vehicle can be improved.

    本发明公开了一种铁路货车高速内轴箱转向架,采用内轴箱方式布置,采用所述一系悬挂装置能够有效减小转向架的轴距,优化构架受力,同时能够减少钢弹簧的挠度,合理布置所述钢弹簧偏置距离和所述转臂长度比例,可以提升减振器减振效果;采用所述二系悬挂装置,所述锥形橡胶弹簧与所述叠层橡胶弹簧串联的组合方式,能够提供车体与转向架合适的垂向悬挂刚度和水平剪切刚度,并且结构简单,同时能够代替空气弹簧,可以在满足空重车的前提下降低成本,通过该转向架一系悬挂方式、二系悬挂方式,可使得转向架具有在横向和纵向的紧凑结构,最大程度降低簧下质量和整体转向架质量,能够显著达到轻量化目的,有利于提高车辆运行稳定性、平稳性和运行速度。
