Patent ID: 7263909

Claim:
An electronically driven locking device for electronically engaging and disengaging a locking element of a motor vehicle, wherein the locking device is coupled to actuating means having a motor and a worm gear, said motor arranged to drive said worm gear and generate kinetic energy resulting in application of a torque to said locking device, said locking device comprising: a gear wheel comprising a gear ring, a hub, an elastic intermediate element and a central axis upon which the gear ring, hub and elastic intermediate element are arranged, wherein each one of said gear ring, hub and elastic intermediate element has a lateral side that is substantially perpendicular to said central axis, wherein said gear ring and hub are joined together by said elastic intermediate element and via a material to material bond, so that the intermediate element is sandwiched between a lateral side of the gear ring and a lateral side of the hub, wherein said gear ring and hub each comprise circumferential teeth, said gear ring teeth being arranged to engage said worm gear such that force from said worm gear is imparted upon said gear ring; and a control disk comprising circumferential teeth arranged to interact with said hub teeth such that rotational force may be exchanged between said control disk and hub, said control disk mechanically linked to said locking element such that said torque is absorbed by said intermediate element.
