Abstract: A wheel mounting and dismounting mechanism for allowing a driver to easily mount and dismount a wheel to the axle of a vehicle. A hub is mounted to the end of a vehicular axle and consists of concentric mounting of several lug studs with a central gear driven mechanism consisting of gear-driven locking arms that are concentrically mounted about the central drive gear and are radially aligned with the lug studs. At the end of each such arm is hook-shaped formation which, when the arm(s) are driven in the proper direction by the central gear, engage the lug studs in the fashion of an ordinary hook sliding over a post or stud. The normal embodiment of the invention contemplates the positioning of the wheel rim over the lug studs, in normal wheel-mounting fasion and subsequent actuation of the central drive-gear mechanism so as to rotate the locking arms into the hook-over-stud position.
