The invention provides an intelligent attack angle self-adaptive two-stage telescopic empennage device which comprises a main wing, two sets of hydraulic telescopic mechanisms and two servo motors, and the two sets of hydraulic telescopic mechanisms are the same in structure and are arranged below the main wing in a bilateral symmetry mode; the two servo motors mounted on the tail vehicle body are arranged in a bilateral symmetry manner and are meshed with the rack body through driving gears to drive the hydraulic telescopic mechanism to stretch and retract front and back; an automobile ECU receives signals of an automobile speed sensor, a brake pedal sensor, an accelerator pedal sensor and a steering wheel angle sensor, and then the automobile ECU outputs the signals to control a servo motor, a hydraulic telescopic mechanism (a first hydraulic cylinder and a second hydraulic cylinder) and a tail wing to stretch out of the tail of an automobile and control the tail wing to rise to the optimal height. Meanwhile, the optimal attack angle (front-back inclination angle) of the empennage can be adjusted through the hydraulic connecting rod mechanism, and the aerodynamic performance and the handling stability of the automobile are improved.
本发明提出了一种智能攻角自适应双级伸缩式尾翼装置,包括有一个主翼,2套液压伸缩机构,两个伺服电机,所述的2套液压伸缩机构结构相同,在主翼下方呈左右对称布置;安装在尾部车身上沟通两个伺服电机呈左右对称布置,通过驱动齿轮与齿条本体啮合,驱动液压伸缩机构前后伸缩;汽车ECU接收车速传感器、制动踏板传感器、加速踏板传感器、方向盘转角传感器的信号,进而汽车ECU输出信号控制伺服电机、液压伸缩机构(第一液压缸、第二液压缸),尾翼伸出汽车尾部,控制尾翼上升到最佳高度,同时可以通过液压连杆机构调节尾翼的最佳攻角(前后倾角),提升汽车空气动力学性能及操纵稳定性。
