摘要： A locomotive bogie driving device, comprising an axle (102), a driven gear (106) mounted on the axle (102) in an interference manner, identical traction motors (104) symmetrically mounted on two sides of the axle (102), and driving gears (107) mounted on rotary shafts of the traction motors (104) in an interference manner respectively. The driving gears (107) on the traction motors (104) on the two sides of the axle (102) engage with the driven gear (106) simultaneously to form a transmission gear pair. The locomotive bogie driving device can significantly increase and even double driving torque and driving power. Moreover, individual traction motors have smaller volume and weight for designated single-axle traction power and traction, thereby providing ample space for a bogie traction rod to cross under the traction motors. Meanwhile, the abrasion matching between the driving gears and the driven gear is improved.
