The invention relates to the technical field of empennage driving devices, and provides a driving device, an empennage and a vehicle, the driving device is used for being connected with a flap and driving the flap to rotate so that the flap can be switched from a first state to a second state, and the driving device drives the length of a first force arm of first driving force of the flap in the first state to the length of a second force arm of second driving force; a second moment arm length smaller than a second driving force for driving the flap in the second state; the downward pressure borne by the flap in the first state is smaller than the downward pressure borne by the flap in the second state. By means of the scheme, the variation amplitude of the total acting force output by the driving device in the state switching process of the driving flap is relatively small, and therefore the durability of the driving device is guaranteed.
本申请涉及尾翼驱动装置技术领域,提供一种驱动装置、尾翼及车辆,驱动装置用于连接襟翼,并驱动襟翼转动,以使得襟翼从第一状态向第二状态切换,驱动装置驱动处于第一状态下的襟翼的第一驱动力的第一力臂长度,小于驱动处于第二状态下的襟翼的第二驱动力的第二力臂长度;其中,襟翼在第一状态下受到的下压力小于襟翼在第二状态下受到的下压力。通过上述方案,可使得驱动装置在驱动襟翼进行状态切换的过程中所输出的总作用力变化幅度相对较小,从而保障驱动装置的耐久性能。
