The fixed-wing unmanned aerial vehicle ground speed reducer comprises an aircraft wheel frame, a tire, a hub and a hollow main shaft, the hub is formed by splicing two single-side hubs of the same structure, follow-up impellers are arranged on the inner sides of the two single-side hubs, centrifugal heat dissipation turbines are arranged on the outer sides of the two single-side hubs, and the two single-side hubs are connected with the hollow main shaft. A fixed impeller is arranged in the center of an inner cavity of the hub and sleeved on the middle section of a hollow spindle, one end of the hollow spindle is open, the other end of the hollow spindle is closed, an oil through hole is formed in the middle section of the hollow spindle, a tire is assembled on the periphery of the hub, the open end of the hollow spindle is connected with an oil nozzle, and the outside of the oil nozzle is connected with an oil can through a high-pressure hose. After hydraulic oil is injected into the hub, air in the hub is compressed, the boiling point of the hydraulic oil is increased, and therefore advanced gasification of the hydraulic oil is avoided; the overall structure is simple and easy to maintain, brake discs, brake pads, reset springs, hydraulic pumps and other components of an existing fixed-wing unmanned aerial vehicle ground speed reducer are omitted, and therefore the total weight of the unmanned aerial vehicle is reduced.
本发明公开了一种固定翼无人机地面减速装置,包括机轮架、轮胎、轮毂和空心主轴,轮毂由两个结构相同的单侧轮毂拼合组成,两个单侧轮毂的内侧均设置有随动叶轮,两个单侧轮毂外侧均设置有离心式散热涡轮,轮毂的内腔正中位置设置有固定叶轮,固定叶轮套接于空心主轴中段,空心主轴的一端为开口,另一端封闭,空心主轴的中段处开有通油孔,轮毂的外周组装有轮胎,空心主轴的开口一端连接有油嘴,油嘴的外部通过高压软管连接有油壶。液压油注入轮毂之后将轮毂内部空气压缩,提升了液压油的沸点,从而避免液压油提前气化;整体结构精简易维护,取消现有固定翼无人机地面减速装置的刹车盘、刹车片、复位弹簧、液压泵等部件,从而减轻无人机总重。
