ANTITHEFT LOCKING DEVICE FOR ATTACHMENT OF WHEEL TO HUB OF AUTOMOBILE Russian patent published in 2013 - IPC F16B41/00 

FIELD: automobile production.

SUBSTANCE: antitheft locking device includes a threaded part, a retaining part intended for installation on an object that is to be fixed, and a drive part intended for introduction into a wheel well, which allows transmitting the tightening or weakening torque to the threaded part by means of a wrench, etc. Connection of the wrench, etc. to the drive part is performed by means of matching grooves on the drive part and the wrench, etc. The drive part includes a cylindrical pin passing along the axis, and an insert in the form of a sleeve having the above grooves on the outer side. The insert is installed along the axis with the force on the cylindrical pin to take up the first position of use with possibility of taking up the second position of use, in which it is inserted deeper on the cylindrical pin; and with that, the insert is connected at rotation to the cylindrical pin by means of friction means. The cylindrical pin and the insert are made so that in the first position the friction means can arrange the transfer of the tightening or weakening moment, and in the second position the friction means cannot arrange the transfer of the tightening or weakening moment.

EFFECT: absence of possibility of unauthorised breaking of this device.
