A motor hold shaft installation type permanent-magnetic direct-drive bogie comprises two frame devices, two permanent-magnetic synchronous traction motors, two triangular elastic supporting devices and four wheel pair box devices, wherein two adjacent front and rear wheel pair box devices are connected through the frame devices, two wheels on the left and right symmetric sides are connected through an axel, the permanent-magnetic synchronous traction motors and the axle are integrated through rotors, and driving is realized by rotating the axel; the two frame devices are symmetrically located on the left side and the right side of the advancing direction of a railway vehicle and are connected by double traction rod devices, and the triangular elastic supporting devices are connected with the permanent-magnetic synchronous traction motors and the double traction rod devices. According to the motor hold shaft installation type permanent-magnetic direct-drive bogie, the permanent-magnetic synchronous traction motors are adopted, rotor excitation power is saved, the motor efficiency is improved, the transmission efficiency is improved further after a gear box device is saved, the wheel base of the bogie is shortened, and the motor hold shaft installation type permanent-magnetic direct-drive bogie has the advantages that energy is saved, environment is protected and the small curve through capacity is high, and can be widely applied to various urban railway traffic vehicles.
