Abstract: An axial fixing device for axially fixing an annular brake disk on a wheel hub of a motor vehicle, the annular brake disk having the same axis of rotation as the hub and including radial ventilation ducts regularly distributed about its periphery. According to the invention, the hub has axial guide pieces in relief, or “lugs”, for co-operating with fluting in an inner peripheral edge of the disk to center the disk, to lock it angularly, and to guide it axially relative to the hub, each lug of the hub having a radial through channel for co-operating with a corresponding ventilation duct of the disk, and the disk is held axially in the hub with play by axial holding means disposed between the disk and the hub.

Abstract: The friction device comprises a non-rotary casing (50) in the form of a cage in which there are received a thrust structure (30), a set of friction disks (21, 22, 23, 24, 25) on a common axis, and a backing structure (40), the casing having a peripheral wall provided with ventilation openings (54). The friction device is actuated by a pneumatic actuator (60) mechanically connected to the central portion of the thrust structure through a central opening in an end wall (51) of the casing. Thermal insulation is arranged between the set of disks (21, 22, 23, 24, 25) and the outside of the casing adjacent to the end wall provided with the bearing unit (11) for the rotary shaft (10), and comprises at least one heat barrier (76-77, 78-79) situated at the bearing unit (11).

Abstract: A rotor disk (20) is arranged between two stator disks (30, 40; 130, 140), the disks being made in thermostructural composite material at least for the wear parts. A first supporting structure (50, 150) has a bell shape with a bottom part (52) whereon rests the first stator disk (30, 130) and part of the skirt (70, 170) linked to the bottom part (52) and encloses the disks (20, 30, 40), the bell-shaped structure having cooling means (170, 174) for evacuating the heat generated by the mutual friction of the disks. A second supporting structure (80, 180) has a part in the shape of an annular support plate whereon rests the second stator disk (40, 140); and the bell-shaped structure bottom part (52) and the support plate (80, 180) are provided with cotters (60) or radial ribs (84) co-operating with the corresponding radial housings (36) formed in the outer surfaces (33, 44) of the stator disks (30, 40; 130, 140) to block the latter in rotation relative to the supporting structures (50, 150; 80, 180).
