Power bogie for 100% low-floor light rail vehicle

A power bogie for a 100% low-floor light rail vehicle is mainly combined and assembled by a framing device, a wheel set axle box locating device, a driving device, a basic braking device and a secondary suspension device. The wheel set axle box locating device utilizes a rigid straight shaft and an elastic vehicle wheels set with the diameter ranging from phi 500mm to phi 580mm, two elastic vehicle wheels are assembled with a vehicle axle in an interference mode, a gearing device is in a compound assembly with a gear box and the basic braking device, a primary spring mounting base and a secondary spring mounting base are of a combined type integral structure, a rigid straight shaft wheel set type 100% low-floor vehicle running gear is achieved, meanwhile, optimization and improvement of other components are utilized cooperatively, so that integrated innovation of power bogie products for the 100% low-floor light rail vehicle is achieved, the innovative structure solves the problems that in the existing same type vehicle, the bearing capacity of a bogie is low, abrasion of tread is fast, maintainability is poor and the like.
