The invention provides an electric unlocking undercarriage downlock tension spring actuator cylinder and a movement method, the actuator cylinder integrates a downlock tension locking function and an electric drive unlocking function, and comprises a static end support lug, a static cylinder, a motor, a speed reducer, a lead screw, a lead screw nut, a lead screw nut limiting bolt, a tension spring, a sliding cylinder and a sliding end support lug; the design scheme that a linear electromechanical actuator is combined with an undercarriage downlock tension spring actuator cylinder is adopted, in the load bearing process of an undercarriage, a tension spring outputs tension to undercarriage lock rods through an actuator supporting lug, the tension locking function is shown outwards, and the two lock rods of the undercarriage are kept to be in contact without loosening; in the unlocking process of the down lock in the ground state, the actuating cylinder has a thrust unlocking function outwards, the length of the actuating cylinder is changed by the electric driving mechanism for limiting, thrust is output to the lock rods of the undercarriage through the support lugs, and the deflection direction between the two lock rods is pushed to be changed; and finally, 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拉力弹簧作动筒及运动方法,作动筒集成了下位锁拉力上锁功能与电驱动解锁功能,包括静止端支耳、静止筒、电机、减速器、丝杆、丝杠螺母、丝杠螺母限位螺栓、拉力弹簧、滑动筒、滑动端支耳;采用直线式机电作动器与起落架下位锁拉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拉力弹簧通过作动器支耳对起落架锁杆输出拉力,对外表现为拉力上锁功能,保持起落架两锁杆间接触不松脱;在地面状态下位锁解锁过程中,作动筒对外表现为推力解锁功能,由电驱动机构改变作动筒长度限位并通过支耳对起落架锁杆输出推力,推动两锁杆间挠度方向改变;最后起落架在起落架收放作动器驱动下实现收起功能。
