The invention relates to a variable empennage system which comprises an empennage body and a driving assembly connected to a vehicle body of a vehicle, the driving assembly is connected with the empennage body and used for driving the empennage body to move between a first position and a second position, and the first position and the second position are both located outside the vehicle body of the vehicle. The first position and the second position are both located on the rear sides of rear wheels of the vehicle, the first position is located on the upper front side of the second position, and when the empennage body is adjusted to the second position, due to the fact that the position of the empennage body descends, wind resistance of the whole vehicle is reduced, and the horizontal distance between the empennage body and the rear wheels of the vehicle is increased; the proportion of the front and rear down pressures of the vehicle is still kept similar while the down pressure of the rear empennage is reduced; the technical problems that in the prior art, empennage angle change only changes vehicle rear wheel downward pressure, if a vehicle is in a second state due to mechanical faults and other reasons, high-speed turning is prone to out-of-control drifting due to front and rear downward pressure proportion change, and out-of-control is caused by unbalanced braking are solved.

    本发明涉及一种可变式尾翼系统,包括尾翼本体和连接在车辆的车身上的驱动组件,驱动组件连接尾翼本体并用于驱动尾翼本体在第一位置和第二位置之间移动,第一位置和第二位置均位于车辆的车身之外,第一位置和第二位置均位于车辆后轮的后侧,第一位置位于第二位置的前上侧,尾翼本体调整至第二位置时,由于尾翼本体位置下降令整车风阻变小,而与汽车后轮之间的水平距离增大,相当于力臂增大,使得在后尾翼下压力降低的同时仍然保持车辆前后下压力比例相近;以解决现有技术中的尾翼角度变化仅改变车辆后轮下压力,若车辆由于机械故障等原因在尾翼处于第二状态时由于前后下压力比例改变导致高速过弯容易失控甩尾及刹车不平衡导致失控的技术问题。
