Abstract
The utility model discloses a B0+B0 axial locomotive bogie, which comprises two two-axle bogie frameworks and a middle framework, wherein the two-axle bogie frameworks and the middle framework are connected in a secondary suspension manner; a traction device is arranged between the two-axle bogie frameworks and the middle framework; and a low-level traction is performed by the traction device through an inclined traction rod. The B0+B0 axial locomotive bogie has the advantages of simple structure, reasonable design, convenience in repair, high adhesion utilization rate, good dynamic property and high curve passing capability. A locomotive adopting the B0+B0 axial locomotive bogie can pass the curve radius of 80m. Compared with the traditional locomotive with a C0-C0 locomotive bogie, the transverse action force of the wheel track of the locomotive with the B0+B0 axial locomotive bogie is reduced by about 70%, so that the abrasion loss of the wheel track is greatly reduced; and the starting traction and the continuous traction are improved by more than 33%.
