The invention discloses a brake airplane wheel cooled by utilizing airplane landing kinetic energy and brake heat. The brake airplane wheel comprises an outer half wheel hub, an unpowered fan, a bearing, an inner half wheel hub and a linkage structure, wherein the outer half wheel hub and the inner half wheel hub are coaxially arranged and are spliced and fixed into a complete wheel hub, the outerhalf wheel hub and the middle portion project towards the right side to form a shaft sleeve, the unpowered fan is arranged on the shaft sleeve of the outer half wheel hub through a bearing and located between the outer half wheel hub and the inner half wheel hub, the linkage structure is arranged on the unpowered fan and the outer half wheel hub, and is in linkage with the unpowered fan and the outer half wheel hub to rotate synchronously when the rotating speed of the outer half wheel hub is high, and the linkage between the unpowered fan and the outer half wheel hub is disconnected when therotating speed of the outer half wheel hub is reduced. According to the invention, the braking energy of the airplane wheel is rapidly guided into external air, so that the temperature of the airplane wheel and the braking device can be rapidly reduced, the cooling efficiency can be improved, and the continuous take-off time interval of the airplane is shortened.
本发明公开了一种利用飞机着陆动能及刹车热降温的刹车机轮,包括外半轮毂、无动力风扇、轴承、内半轮毂和联动结构;所述外半轮毂与内半轮毂同轴设置,并且拼合固定为完整轮毂;所述外半轮毂和中部向右侧方向突出形成轴套;所述无动力风扇通过轴承设于外半轮毂的轴套上,并且无动力风扇位于外半轮毂和内半轮毂之间;所述联动结构设于无动力风扇和外半轮毂上,联动结构在外半轮毂高转速时联动无动力风扇与外半轮毂同步转动,在外半轮毂转速降低时断开无动力风扇与外半轮毂联动。本发明实现快速将机轮刹车能量导向外部空气中,快速降低机轮及刹车装置的温度,提高降温效率,缩短飞机连续起飞的时间间隔。
