1. An emergency wheel attachment for a vehicle wheel having a rim and a tire arranged on the rim, the emergency wheel attachment configured to be placed onto an outside of the vehicle wheel and to enable a driving operation with a restricted tire function in an operating state in which the emergency wheel attachment is attached to the vehicle wheel, the emergency wheel attachment comprising:
an annular mounting unit configured to mount the emergency wheel attachment on the vehicle wheel, and
an annular tread unit configured to contact, in the operating state of the emergency wheel attachment, a road on which the vehicle wheel is intended to roll,
wherein the annular mounting unit is provided with at least two retaining claws configured to fasten the annular mounting unit to the rim of the vehicle wheel by engaging behind a rim flange of the rim, wherein at least one of the retaining claws is radially movable relative to the mounting unit so as to change a distance of the at least one of the radially movable retaining claws from a center point of the annular mounting unit,
wherein the annular mounting unit has an annular actuating element, rotatable about an axis of rotation coinciding with a vehicle wheel axis in the operating state of the emergency wheel attachment and forming part of a gear mechanism configured to convert a rotation of the annular actuating element into a radial movement of the at least one of the radially movable retaining claws,
and wherein the annular mounting unit includes a drive device configured to be coupled to the annular actuating element and the actuation of which causes a rotation of the annular actuating element.
