The invention provides an electric unlocking undercarriage downlock thrust spring actuator cylinder and a movement method, the actuator cylinder integrates a downlock thrust locking function and an electric drive unlocking function, and comprises a static end support lug, a motor, a speed reducer, a static cylinder, a lead screw, a lead screw nut, a lead screw nut limiting bolt, a thrust spring, a sliding cylinder and a sliding end support lug; a design scheme that a linear electromechanical actuator is combined with an undercarriage down lock thrust spring actuating cylinder is adopted; in the load bearing process of the undercarriage, the thrust spring outputs thrust to the undercarriage locking rods through the actuator supporting lugs, the thrust locking function is shown outwards, and the two locking rods are kept in contact and are not loosened; in the unlocking process of the down lock in the ground state, the pull unlocking function is shown outwards, the electric driving device changes the length of the actuating cylinder for limiting, pull force is output to the lock rods through the supporting lugs, and the deflection direction between the two lock rods is pushed to be changed; the landing gear is driven by the landing gear folding and unfolding actuator to achieve the folding function.

    本发明提供了一种电动解锁的起落架下位锁推力弹簧作动筒及运动方法,作动筒集成了下位锁推力上锁功能与电驱动解锁功能,包括静止端支耳、电机、减速器、静止筒、丝杆、丝杠螺母、丝杠螺母限位螺栓、推力弹簧、滑动筒和滑动端支耳;采用直线式机电作动器与起落架下位锁推力弹簧作动筒相结合的设计方案;起落架承受载荷过程中,由推力弹簧通过作动器支耳对起落架锁杆输出推力,对外表现为推力上锁功能,保持两锁杆间接触不松脱;在地面状态下位锁解锁过程中,对外表现为拉力解锁功能,由电驱动装置改变作动筒长度限位并通过支耳对锁杆输出拉力,推动两锁杆间挠度方向改变;起落架在起落架收放作动器驱动下实现收起功能。
