The invention discloses a three-axle power bogie based on a 100% low-floor tramcar. The three-axle power bogie comprises a rectangular framework, wheel set devices, primary suspensions, secondary suspensions, vertical dampers and transverse dampers. The three wheel set devices are arranged on the rectangular framework forwards and backwards at intervals, axles corresponding to the wheel set devices located on the front side and the rear side are power drive shafts, an axle corresponding to the wheel set device located in the middle is a non-power drive shaft, one side of each power drive shaft is provided with a power drive device, the other side of each power drive shaft is provided with a braking device and a grounding device, the two sides of the non-power drive shaft are provided with braking devices, and the two power drive devices are installed outside different side beams of the rectangular framework and arranged in a skew symmetry mode. The parts except for the power drive devices and the transverse dampers are symmetrically distributed according to the center point of the rectangular framework. Under the same load condition, compared with a two-axle bogie, the whole car acceleration is high, climbing capacity is high, adhesive force is large, and axle loads are effectively reduced.
