A power
bogie adopting traditional wheel sets for a 100% low-floor
light rail vehicle comprises a framework device, wheel set assemblies, first-series springs, second-series springs, second-series vertical oscillating dampers, second-series transverse oscillating dampers, second-series transverse buffers, single traction rods, side rolling preventing torsion rods, a flexible suspension longitudinal driving device, a
hydraulic brake unit and a magnetic rail
brake and is characterized in that the wheel set assemblies adopt wheel shaft type structures, journal boxes are built in, the wheels are elastic wheels in a
diameter Phi of 500-580mm, and two sets of side rolling preventing torsion rods are mounted on the outer side of a cross beam. According to the
bogie, the wheel set assemblies adopt the wheel shaft type structures, the journal boxes are built in, and the wheels are the elastic wheels in the
diameter of 500-580mm, so that the restoring problem of wheel sets during linear running and the guide problem of the wheels during curvy running are solved; the two sets of side rolling preventing torsion rods are mounted on the outer side of the cross beam, and the side rolling preventing performance of the vehicle is improved. The 100% low-floor requirement of the vehicle body is successfully realized by the
bogie, and meanwhile, the structure of the bogie is simplified. All the parts are mature products, and the
modular design of the bogie is facilitated.
