A device (1) for braking a wheel (2) of an aircraft, the hub (5a, 5b) of which is mounted for rotation about an axle (6), comprises a stack of wheel discs (11) screwed on a torque tube (12) attached to the axle and internally equipped with a thermal insulation (20) extending opposite an outer surface (5.1) of the hub facing the stack of wheel discs, in order to protect the hub from thermal radiation generated by the stack of wheel discs. The insulation comprises a tubular body (21) coaxial with the torque tube and a plurality of retaining tabs (22) elastically deformable and fixed to the tubular body, each retaining tab and an inner surface (12.1) of the torque tube comprising additional raised portions intended to engage one another so as to axially secure the insulation inside the torque tube. Wheel, landing gear and aircraft provided with such a brake device.
一种用于制动飞行器的轮(2)的装置(1),其轮毂(5a、5b)安装成绕轮轴(6)旋转,包括拧在扭矩管(12)上的轮盘叠堆(11),扭矩管附接到轮轴并在内部配备有隔热件(20),隔热件与轮毂的面向轮盘叠堆的外表面(5.1)相对延伸,以保护轮毂免受轮盘叠堆所产生的热辐射。隔热件包括与扭矩管同轴的管状主体(21)和多个保持突片(22),这些保持突片弹性可变形并固定到管状主体,每个保持突片和扭矩管的内表面(12.1)包括意图彼此接合的附加升高部分,使得将隔热件轴向固止在扭矩管内部。设有这样的制动装置的轮、起落架和飞行器。
