The system for mounting the wheel (10) comprises a wheel hub (11) which engages an axle journal (12) of the motor vehicle and on which a wheel (10) to be mounted is fastened by a central fastening element which is formed as a fastening screw (14), part of which has an external screw-thread (15) engageable with an internal thread (16) of a shaft (17) of the wheel hub (11), a slit cone (18) co-operating with the fastening screw (14) in such a way that it is pressable against the wheel (10) when the fastening screw (14) is fastened to the wheel hub (11), wherein the slit cone (18) is supported on an outer surface of the wheel-hub shaft (17) and forms a non-positive connection to it. The fastening screw (14) is locked by a bolt (26) with external teeth (27) which engage teeth (28) of the screw in one axial position, movement of the bolt to a second position against spring bias releasing teeth engagement. A brake disc (38) carries retaining bolts (39) held by respective sleeves (40) and screws (41) and which at least partly extend into respective recesses (42, 43) in the wheel (10) and hub (11). |
