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.

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 open at both ends and regularly distributed about its periphery, wherein said 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, which transmit the braking torque of the disk, having a radial through channel for co-operating with a corresponding ventilation duct of the disk, and wherein the disk is held axially in the hub with play by axial holding means disposed between the disk and the hub, said axial holding means comprises a plurality of radial pegs, each peg being engaged firstly in the radial through channel of the lug of the hub and secondly in the radial ventilation duct facing it in the brake disk.
