Locomotive three-axis radial bogie

The invention discloses a locomotive three-axis radial bogie. In order to reduce wheel set abrasion and improve the curve passing performance of a locomotive, the locomotive three-axis radial bogie is mainly composed of three sets of wheel set shaft box assemblies, three sets of driving units, a framework, a single stage suspension device, a secondary suspension device, a set of traction device, three motor suspension devices, a brake device, and a radial device. The framework is mainly composed of a front end beam, two side beams, a traction beam, a middle beam, and a back end beam. The radial device is mainly composed of a pivot, a front guide beam, a transition coupling pull rod, a supporting rod, a turning arm, a coupling pull rod, and a back guide beam. The locomotive three-axis radial bogie has the capacity of automatically tending to a radial position, improves the curve passing speed of the locomotive, and reduces wheel set angle of attack, and reduces wheel rail transverse force, so that wheel rail abrasion is reduced, and the curve passing performance of the locomotive is improved.
