The invention discloses an auxiliary framework type radial bogie suitable for various foundation brake devices. The auxiliary framework type radial bogie consists of a wheel set assembly, a side frame assembly, a rubber pile, a swing bolster assembly, the foundation brake devices, a rolling bearing device, a wheel set radial device, a central suspension device and an elastic side bearing assembly. The wheel set radial device is formed by a pair of U-shaped auxiliary frameworks; four groups of anti-falling mounting bases are arranged on the auxiliary frameworks and are connected above the round pins, and anti-falling bolts, nuts, gaskets and cotter pins are mounted in the anti-falling mounting bases; and a structural arm of the auxiliary framework is of a concave solid structure. The adaptability of the swing bolster is improved and the light weight is realized by optimally designing the assembly hole of the abdomen brake device of the swing bolster; the auxiliary framework part adopts a variable cross-section solid design to meet the assembling clearance requirements of various brake devices, and the application is reliable; according to the auxiliary framework type radial bogie suitable, the characteristics of low power, low abrasion, excellent curve passing capacity and the like of the bogie are guaranteed, and it is also guaranteed that the bogie can be provided with different basic braking devices.
本发明公开了一种适应多种基础制动装置的副构架式径向转向架,由轮对组成、侧架组成、橡胶堆、摇枕组成、基础制动装置、滚动轴承装置、轮对径向装置、中央悬挂装置和弹性旁承组成构成,轮对径向装置由一对U形副构架构成,副构架上设置四组防脱安装座,各连接圆销上方、防脱安装座中安装用于防脱螺栓、螺母、垫圈和开口销;副构架的结构臂为凹形实心结构。本发明通过优化设计摇枕腹部制动装置组装孔,提高了摇枕的适应性,实现轻量化;副构架部位采用变截面实心设计满足各型制动装置配装间隙要求,运用可靠;本发明副构架式径向转向架结构不仅保证转向架低动力、低磨耗以及优良的曲线通过能力等特点,也保证了转向架可安装不同的基础制动装置。
