Abstract: A vehicle wheel for the purpose of slow speed temporary movement of the vehicle whereby the inner portion of the wheel disc includes a curved surface disposed in rotating contact with the beveled surface of the cylinder element of the attachment hub. The wheel disc and the attached tire extend outwardly from the attachment hub. The attachment hub includes the cylinder with a securing ring affixed to the inwardly extending portion of the cylinder and disposed in abutting relation with the inner surface of the wheel disc wherein the outer surface of the cylinder is disposed between the securing ring and a flange.

Abstract: An auxiliary wheel including a wheel hub and a tire, the wheel hub includes an outer wheel hub and an inner wheel hub and the tire is mounted on the outer wall of the outer wheel hub. The outer wheel hub and the inner wheel hub are detachably connected through a first connection component. When the first connection component unlocks the connection between the outer wheel hub and the inner wheel hub, relative rotation is generated between the outer wheel hub and the inner wheel hub with bearings disposed between the inner wheel hub and the outer wheel hub to reduce friction. Friction is reduced between the outer and inner wheels, thereby increasing the upper limit of the auxiliary wheel rotation speed. A nut and bolt arrangement is disposed in the nut groove to firmly fix the ring on the outer wall of the outer wheel.
