The invention is suitable for the technical field of locomotive equipment, and provides a modularized locomotive bogie frame. Comprising two side beams which are arranged in parallel, and a front end beam, a traction beam, a cross beam and a rear end beam are sequentially arranged between the two side beams; the two ends of the front end beam are fixedly installed at the first ends of the two side beams respectively, and the two ends of the traction beam, the two ends of the cross beam and the two ends of the rear end beam are fixedly installed on the inner sides of the two side beams respectively. Wherein the two ends of the rear end beam are fixedly mounted at the second ends of the two side beams; the front end beam, the traction beam, the cross beam and the rear end beam are arranged in parallel; the front end beam is of a sinking structure, the traction beam is of a sinking type camber beam, and the side beams are of a box type welding structure with the middle higher than the two ends. The three-axle bogie is applied to a center pin traction mode, the traction beam is of a sunken camber beam structure, and the three-axle bogie has the advantages of being low in traction point, low in framework height, short in framework length, small in framework section, light in framework weight, good in installation base structure universality and the like.
本发明适用于机车设备技术领域,提供了一种模块化机车转向架构架;包括:两个侧梁,两个侧梁平行布置,两个侧梁之间依次布置有前端梁、牵引梁、横梁和后端梁;所述前端梁两端分别固定安装在两个侧梁的第一端,所述牵引梁、横梁和后端梁的两端分别固定安装在两个侧梁内侧;其中后端梁两端固定安装在两个侧梁的第二端;所述前端梁、牵引梁、横梁和后端梁平行设置;所述前端梁为下沉结构,牵引梁为下沉式弯梁,所述侧梁为中间高两端低的箱型焊接结构。本发明应用于中心销牵引方式的三轴转向架,其牵引梁采用下沉式弯梁结构,具有牵引点低、构架高度低、构架长度短、构架截面小重量轻、安装座结构通用性好等特点。
