The invention relates to the technical field of bogies, in particular to a bogie frame which comprises a mandrel component, an embedded part and a wrapping layer. The mandrel component is of a hollow tubular structure and comprises two side beam core molds arranged in parallel and a cross beam core mold perpendicularly arranged between the two side beam core molds. The embedded parts are embedded in the side beam core molds and the cross beam core molds at intervals; the wrapping layer integrally wraps the outer layers of the side beam core molds and the cross beam core molds; the core mold component is of a split type structure or an integrally-formed structure, and the split type structure comprises a left-right split type structure and an up-down split type structure. When the split type structure is a left-right split type structure, the split type structure further comprises a connecting piece used for connecting the side beam core mold and the cross beam core mold. The embedded part is embedded in the core mold component of the hollow pipe structure, and the wrapping layer is laid after the core mold component is formed, so that the overall strength of the bogie frame is improved, the stress concentration phenomenon is reduced, the overall weight of the bogie frame is reduced, and the requirement for train acceleration is better met.
本发明涉及转向架技术领域,尤其涉及一种转向架构架,包括芯模构件、预埋件和包裹层;芯模构件为空心管状结构,包括两平行设置侧梁芯模和垂直设置在两侧梁芯模之间的横梁芯模;预埋件间隔埋设在侧梁芯模和横梁芯模中;包裹层整体包覆在侧梁芯模和横梁芯模的外层;其中,芯模构件为分体式或一体成型式结构,分体式结构包括左右分体式和上下分体式;当分体式结构为左右分体式时,还包括用于连接侧梁芯模和横梁芯模的连接件。本发明通过在空心管结构的芯模构件中埋设预埋件、并且在芯模构件成型后通过包裹层的铺设,提高了转向架构架的整体强度,减少了应力集中现象,并且减轻了转向架构架的整体重量,更加符合列车提速的需求。
