Abstract
A fastening arrangement for a rim of a wheel on a wheel hub of a wheel carrier of a motor vehicle. The fastening arrangement includes a central screw which, on a fastening portion, has an external thread which engages in an internal thread of a step of the wheel hub. A tensioner produces a force-fitting connection between the wheel hub step and the central screw. A locking arrangement prevents unintentional release of the central screw. The locking arrangement has a carrier member and a blocking member, wherein the blocking member is pretensioned in relation to the carrier member by a locking spring member and is displaceable in the axial direction. The blocking member is arranged captively in the carrier member by a securing mechanism.

A fastening arrangement for a wheel on a wheel hub of a wheel carrier of a motor vehicle, the fastening arrangement comprising:
- a central screw which, on a fastening portion, has an external thread which engages in an internal thread of a step of the wheel hub,
- a tensioning means which produces a force-fitting connection between the wheel hub step, the wheel and the central screw,
- a locking arrangement which, in a closure position, prevents unintentional release of the central screw, wherein the locking arrangement has a carrier member and a blocking member,
- wherein the blocking member is pretensioned in relation to the carrier member by a locking spring member and is displaceable in an axial direction,
- wherein the blocking member is arranged captively in the carrier member by a securing means,
- wherein a relative movement of the carrier member and the blocking member has the effect that an engagement of clamping members with toothing members of the carrier member is released, and in that the clamping members can be brought into an untoothed plane of a sliding surface of the carrier member.
