The invention discloses a locomotive bogie driving device. The locomotive bogie driving device comprises one axle, wherein a driven gearwheel is arranged on the axle in an interference mode, and identical traction motors are symmetrically arranged on the two sides of the axle; and driving pinions are arranged on rotating shafts of the traction motors in an interference mode correspondingly, and the driving pinions of the traction motors on the two sides of the axle are simultaneously meshed with the driven gearwheel to form a transmission gear pair. The driving torque and the driving power ofthe locomotive bogie driving device can be obviously increased and even doubled; and for appointed single-shaft traction power and traction force, the size and the weight of the single traction motorof the locomotive bogie driving device are smaller, so that huge space convenience is provided for a bogie traction rod to pass through the position below the traction motors; and in addition, the abrasion matching performance of the driving pinions and the driven gearwheel of the locomotive bogie driving device is better.
本发明公开了一种机车转向架驱动装置,包括一根车轴,所述车轴上过盈安装从动大齿轮,所述车轴的两侧对称安装相同的牵引电机,所述牵引电机的转轴上分别过盈安装主动小齿轮,且所述车轴两侧的牵引电机的主动小齿轮同时与所述从动大齿轮啮合形成传动齿轮副。本发明的驱动扭矩和驱动功率可以显著增大甚至翻倍;且对于指定的单轴牵引功率和牵引力,本发明单个牵引电机的体积和重量都会更小,从而为转向架牵引杆从牵引电机下方穿过提供了巨大的空间便利。此外,本发明的主动小齿轮与从动大齿轮的磨耗匹配性更好。
