The invention discloses an electric driving bogie for a subway engineering vehicle. The electric driving bogie comprises a framework, two pairs of wheel sets, an axle box, a plurality of primary suspension systems, a secondary suspension system, a driving device, a traction device, an axle box connecting device, a braking device, a weighing device and a grounding device. The electric driving bogie has the beneficial effects that problems such as center plate bearing and longitudinal impact of traction are solved by adopting a rubber-metal pad bearing plus traction rod traction pattern; by adopting a unit braking device for replacing a conventional lever braking device, the daily maintenance free is realized, and the maintenance amount is reduced; compared with the structure of a substrate coach bogie, the structure of the bogie is simple; the structural pattern of the bogie is optimized according to the requirements of the subway engineering vehicle; rubber-metal pad bearing is used for replacing air spring bearing and is supplemented by a device for preventing the side rolling of a vehicle body; a single traction rod is used for replacing a Z-shaped double traction rod and a center pin; an interface of the vehicle body and the structure of the bogie are simplified; and the manufacturing manufacturability is improved.
