The invention discloses a longitudinal motor type modular power bogie, and belongs to the field of longitudinal motor type railway vehicle bogie devices. The modular power bogie comprises a bidirectional output shaft motor, two wheel sets, four brake clamp units, four primary steel springs, four primary vertical shock absorbers, two anti-snaking shock absorbers, two secondary vertical shock absorbers, two gearboxes, two secondary transverse shock absorbers, two air springs, two forged piece side beams, a longitudinally-arranged motor shell, four wheel set built-in primary suspension axle box devices, a center traction seat mechanism, two side beam balance connecting rods, two combined connecting seats, four shell side beam connecting columns, an n-shaped anti-side-rolling torsion bar mechanism and a traction seat fixing and shock absorbing mechanism. According to the invention, the framework space can be greatly saved, the compact layout of the wheel set built-in primary suspension axle box devices can be implemented, the motor control program can be simplified, the electric energy utilization and conversion efficiency and the control efficiency can be improved, and the energy-saving and environment-friendly properties of the train can be enhanced.
