The invention relates to the technical field of braking systems, in particular to an electro-hydrostatic braking system of an unmanned aerial vehicle. The electro-hydrostatic brake system of the unmanned aerial vehicle is only provided with two sets of hydraulic pipelines; wherein one set comprises a first hydraulic power unit, a first pipeline, a first normally open solenoid valve, a second pipeline and a first hydraulic braking module; the other set comprises a second hydraulic power unit, a third pipeline, a second normally open solenoid valve, a fourth pipeline and a second hydraulic brake module; when the first hydraulic power unit breaks down, the flight controller controls the first normally-open electromagnetic valve to be closed and controls the normally-closed electromagnetic valve to be opened, so that oil is supplied to the first hydraulic braking module through the second hydraulic power unit. When the second hydraulic power unit breaks down, the flight controller controls the second normally-open electromagnetic valve to be closed and controls the normally-closed electromagnetic valve to be opened, so that oil is supplied to the second hydraulic braking module through the first hydraulic power unit. The air load weight of the unmanned aerial vehicle is reduced, so that the effective load of the unmanned aerial vehicle is improved.
本发明涉及刹车系统技术领域,特别涉及一种无人机电静液刹车系统;本发明提出的无人机电静液刹车系统仅设置有2套液压管路;其中1套为第一液压动力单元‑第一管路‑第一常开电磁阀‑第二管路‑第一液压制动模块;另1套为第二液压动力单元‑第三管路‑第二常开电磁阀‑第四管路‑第二液压制动模块;当第一液压动力单元故障时,飞行控制器控制第一常开电磁阀关闭,并控制常闭电磁阀打开,以通过第二液压动力单元给第一液压制动模块供油;当第二液压动力单元故障时,飞行控制器控制第二常开电磁阀关闭,并控制常闭电磁阀打开,以通过第一液压动力单元给第二液压制动模块供油;降低了无人机的空载重量,从而提升无人机的有效载荷。
