The invention discloses a power wheel electric driving device of a civil aircraft undercarriage, which comprises an aircraft wheel carrier and an aircraft wheel hub, the lower left side of the aircraft wheel carrier is connected with a left aircraft wheel tire through a working rod, and the lower right side of the aircraft wheel carrier is fixedly connected with a right aircraft wheel tire througha working rod; the outer side of the airplane wheel hub is sleeved with a left airplane wheel tire, a cavity is formed in the airplane wheel hub, meanwhile, a rack is fixedly installed in the airplane wheel hub, a first open hole is formed in the upper side of the interior of the airplane wheel hub, and a second open hole is formed in the lower side of the interior of the airplane wheel hub. Thepower wheel electric driving device of the civil aircraft undercarriage is provided with the four sets of planetary gears, when any set is damaged, transmission work can be conducted through the otherthree sets, a sun gear transmission mode is replaced, the friction coefficient of the gears is reduced, and the load of a motor is reduced; and the stability of the four groups of planetary gears during working is ensured.
本发明公开了一种民用飞行器起落架的动力机轮电驱动装置,包括机轮架和机轮轮毂,所述机轮架左下侧通过工作杆与左机轮轮胎相连接,且机轮架右下侧通过工作杆与右机轮轮胎固定连接;所述机轮轮毂外侧套接有左机轮轮胎,且机轮轮毂内部开设有空腔,同时机轮轮毂内部固定安装有齿条,机轮轮毂内部上侧开设有第一开孔,且机轮轮毂内部下侧开设有第二开孔。该民用飞行器起落架的动力机轮电驱动装置,具有四组行星齿轮,任意一组发生损坏的时候,可依靠其余三组进行传动工作,取代太阳轮传动的方式,减少齿轮的摩擦系数,降低电机的负荷;保证四组行星齿轮在工作时候稳定性的特点。
