The telescopic aircraft landing gear comprises a driving assembly, a buffer and an aircraft wheel assembly, the aircraft wheel assembly comprises a connecting rocker arm and a telescopic rod, the connecting rocker arm is connected with an aircraft wheel, the connecting rocker arm is connected with a torque arm, and normal work of the device is guaranteed; the telescopic rod is hinged to the connecting rocker arm, so that the driving assembly can drive the telescopic rod to move through the transmission mechanism, the connecting rocker arm can rotate relative to the buffer, the angle between the connecting rocker arm and the buffer is changed, and therefore the overall length of the telescopic aircraft landing gear is adjusted. When the undercarriage is folded, the overall length of the undercarriage is shortened while the undercarriage is folded through the driving assembly, the transmission mechanism is arranged in the buffer, the end, connected with the transmission mechanism, of the telescopic rod extends into the buffer, and when the undercarriage is folded, the requirement for the storage space of the aircraft is met.

    本发明公开一种可伸缩式飞机起落架,包括驱动组件、缓冲器和机轮组件,机轮组件包括连接摇臂和伸缩杆,连接摇臂与机轮相连,连接摇臂连接有扭力臂,保证装置的正常工作;伸缩杆与连接摇臂铰接,使得驱动组件能够利用传动机构带动伸缩杆运动,以使连接摇臂能够相对于缓冲器转动,改变连接摇臂与缓冲器的角度从而调整可伸缩式飞机起落架的整体长度,在飞机起飞着陆的时候,起落架放下且长度增长,使飞机的离地间隙满足飞行要求,起落架收起时,通过驱动组件在收起起落架的同时,同时使起落架整体长度缩短,且传动机构设置于缓冲器内,伸缩杆与传动机构相连的一端也伸入缓冲器内,在起落架收起时,满足飞机的收藏空间要求。
