The invention relates to a hydraulic drive two-way load compensation system for helicopter control. The hydraulic drive two-way load compensation system comprises a pressure accumulator, a load compensation actuator and a connecting rod mechanism. When the main hydraulic system works normally, part of hydraulic energy is stored in the energy accumulator, when the main hydraulic system fails in pressure supply, the energy stored in the energy accumulator acts on the load compensation actuator, and power is transmitted through the connecting rod mechanism to act on the variable-pitch pull rod or the control surface, so that bidirectional control assistance is realized. The system can be used for emergency control or position keeping of helicopter blades or fixed-wing aircraft control surfaces, contains few accessories, is simple and reliable, and has the advantages of being high in energy utilization rate, stable in pressure, high in integration degree, small in size, light in weight and high in reliability.

    本发明涉及一种用于直升机操纵的液压驱动双向负载补偿系统,包括蓄压器、载荷补偿作动器、连杆机构;在主液压系统正常工作时将部分液压能量储存在蓄能器中,在主液压系统供压失效故障时,储存在蓄能器的能量作用在载荷补偿作动器上,并通过连杆机构传动动力作用于变距拉杆或舵面,实现双向操纵助力。本发明可用于直升机桨叶或定翼机舵面应急操纵或位置保持,该系统包含的附件少,简单可靠,具有能源利用率高、压力稳定,集成度高,体积小、重量轻,可靠性高的特点。
