The invention discloses an aircraft braking wheel with a heat insulation device, and belongs to the technical field of aviation wheel braking. The airplane brake wheel comprises an airplane wheel assembly and a brake assembly, and is characterized in that devices for heat insulation are designed in the airplane wheel assembly and the brake assembly and comprise a heat insulation ring, a heat insulation block, a heat insulation barrel and a heat insulation ring. The heat insulation ring is fixedly arranged on the outer surface of the guide rail in a sleeving mode and acts together with the composite heat insulation screen, the brake disc assembly is fully surrounded, and heat transfer from the brake disc to the inner wall of the hub with air as a medium is blocked. And the heat insulation block is arranged between the guide rail and the hub to block heat transfer from the brake disc to the inner wall of the hub by taking a solid as a medium. The heat insulation barrel is installed in an inner cavity of the brake shell, and the heat insulation ring is installed between the supporting ring and the brake shell reinforcing ribs to jointly block heat transfer from the brake disc to the brake shaft. According to the invention, the heat transfer efficiency in the brake wheel of the airplane is reduced, the normal work of the brake wheel assembly is ensured, and the failure rate caused by high temperature is reduced.
本发明一种带隔热装置的飞机刹车机轮,属于航空机轮刹车技术领域。所述飞机刹车机轮包括机轮组件和刹车组件,特点在于本发明在机轮组件和刹车组件中设计了用于隔热的装置,包括隔热环、隔热块、隔热筒、隔热圈。隔热环套装固定于导轨外表面,与复合式隔热屏共同作用,实现刹车盘组件全包围,阻隔由刹车盘向轮毂内壁以空气为介质的热传递。隔热块安装于导轨与轮毂之间,阻隔由刹车盘向轮毂内壁以固体为介质的热传递。隔热筒安装于刹车壳体的内腔,隔热圈安装于支撑环和刹车壳体加强筋之间,共同阻隔由刹车盘向刹车轴的热传递。本发明降低了飞机刹车机轮中的热传递效率,保证了刹车机轮组件正常工作,降低了因高温引起的故障率。
