Abstract
A fastening device for a nut comprises a fastening part configured to engage in a screw element, a securing part configured to engage in the nut, and an intermediate part providing a non-positive connection between the fastening part and the securing part, wherein the intermediate part is made of a restorable material and is designed to apply a restoring torque directed at the original state during a rotation of the securing part in relation to the fastening part.
Claims12
A fastening device for an axle nut, comprising:
- a fastening part engaging an axially-extending groovelike recess of a screw element of a vehicle axle, wherein the fastening part includes at least one fastening segment that is adapted to engage with an inner wall of a screw element of a vehicle axle, wherein the at least one fastening segment comprises a pair of fastening elements arranged opposite each other;
- a securing part engaging an axle nut that is threadably received on the screw element of the vehicle axle;
- and
- an intermediate part coupling the fastening part and the securing part, wherein the intermediate part comprises a sheetlike configuration;
- wherein the intermediate part comprises an elastically deformable material that applies a restoring torque to the securing part upon rotation of the securing part relative to the fastening part.
