<p>The invention concerns a friction device comprising a non-rotating housing (50) shaped like a cage wherein are housed a thrust structure (30), an assembly of coaxial friction disks (21, 22, 23, 24, 25) and a support structure (40), the housing having a peripheral wall provided with ventilation apertures (54). The friction device is actuated by pneumatic actuator (60) mechanically linked to a central part of the thrust structure, through a central opening of an end wall (51) of the housing. Heat insulating means are arranged between the disk assembly (21, 22, 23, 24, 25) and the housing outside on the side of the end wall provided with a bearing (11) for the rotary shaft (10), and comprise at least a thermal barrier (76-77, 78-79) located at the bearing (11).</p> |
