The invention discloses an aircraft wheel lock for a small unmanned helicopter and an undercarriage system of the unmanned helicopter, in an aircraft wheel lock assembly, an aircraft wheel lock shell is fixedly mounted on an undercarriage, and an aircraft wheel lock cylinder body, the aircraft wheel lock shell and a static part in an aircraft wheel friction assembly are connected and fixed through a connecting piece; an oil storage tank device, a pressure storage device and a piston mounting cavity are formed in the airplane wheel lock cylinder body, and an airplane wheel lock piston is mounted; a one-way oil way is arranged from the oil storage tank device to the pressure storage device; an oil pressing path is arranged from the pressure storage device to the piston mounting cavity, and an oil return path is arranged from the piston mounting cavity to the oil storage tank device; the movement direction of the airplane wheel lock piston is controlled by controlling all oil ways in the airplane wheel lock assembly, so that the airplane wheel lock piston is tightly attached to or loosened from the airplane wheel friction assembly. According to the technical scheme, the problem that the unmanned helicopter does not have the skating landing capacity or the autorotation gliding capacity is solved.
本发明公开一种用于小型无人直升机的机轮锁和无人直升机的起落架系统,机轮锁组件中,机轮锁壳体固定安装在起落架上,且机轮锁缸体、机轮锁壳体与机轮摩擦组件中的静部件通过连接件连接固定;机轮锁缸体内部形成储油箱装置、蓄压装置和活塞安装腔,并安装有机轮锁活塞;从储油箱装置到蓄压装置具有单向油路;从蓄压装置到活塞安装腔具有压油油路,从活塞安装腔到储油箱装置具有回油油路;通过对机轮锁组件中各油路的控制,以控制机轮锁活塞的运动方向,使其与机轮摩擦组件紧密贴合或松开。本发明的技术方案解决了无人直升机不具备滑跑着陆能力,也不具备自转下滑能力的问题。
