A double-motor anti-skidding electric control brake system is of a double-motor structure and comprises a flight control computer, a normal brake system, an emergency brake system and an anti-skidding electric brake control box, and the anti-skidding electric brake control box is used for receiving instructions of the flight control computer and feeding back brake system state, brake pressure and airplane wheel speed information. The anti-skid electric brake control box controls the normal brake system to be powered on according to an instruction of the flight control computer so that the normal brake system can output corresponding brake pressure, and in the normal anti-skid control process, when the anti-skid electric brake control box detects that the normal brake system breaks down, the anti-skid electric brake control box is switched to the emergency brake system from the normal brake system, and the emergency brake system is switched to the emergency brake system. And system switching is realized. According to the system, double-motor anti-skid braking is adopted, double-motor braking is adopted for emergency braking, single-actuator braking is adopted for limit braking, and therefore the operation reliability of the braking system is improved, and the use safety of an airplane is effectively improved.
一种双电机防滑电控刹车系统,采用双电机结构,包括飞控计算机、正常刹车系统、应急刹车系统和防滑电刹车控制盒,所述防滑电刹车控制盒用于接收飞控计算机指令并反馈刹车系统状态、刹车压力及机轮速度信息,所述防滑电刹车控制盒根据飞控计算机指令控制正常刹车系统上电使正常刹车系统输出相应刹车压力,在正常防滑控制过程中,当防滑电刹车控制盒检测到正常刹车系统故障时,防滑电刹车控制盒由正常刹车系统切换至应急刹车系统,实现系统切换。本发明系统采用双电机防滑刹车,应急刹车采用双电机刹车,极限刹车采用单作动器刹车,从而提高刹车系统运行可靠性,有效提高飞机使用安全性。
