Kind Code:
A
Abstract:
To provide an anti-loosening device for a fastening unit of a wheel.SOLUTION: An anti-loosening device 1 is configured to be arranged within a wheel hub H along an axial direction, so that a main axis of the anti-loosening device coincides with a wheel axis W. The anti-loosening device 1 comprises: a gear 3 arranged to cooperate with inner teeth H3; an elastic element 5 extending axially with respect to the gear 3; and a coupling element 8 provided in a sector of the gear 3, and arranged to receive a corresponding fastening member 10. The anti-loosening device is arranged to create a compressed configuration, wherein the gear is decoupled with respect to the inner teeth, and is arranged within a cavity portion provided on an inner surface H2 of the wheel hub, so as to allow rotation of the anti-loosening device around the main axis. The coupling element is arranged to be radially aligned with respect to each anti-rotation sector 9 provided on a fastening unit, in such a way that in the final assembled condition, the fastening member coupled to the coupling element cooperates with the anti-rotation sector, to avoid loosening of the locking unit 2.SELECTED DRAWING: Figure 1
