Abstract:
Disclosed is an auxiliary wheel comprising a wheel hub and a tire. The auxiliary wheel is fixedly mounted on a wheel of an automotive vehicle in a manner that the auxiliary wheel and the wheel have a common rotary axis. The auxiliary wheel may further comprise one or more locking components located on the wheel hub, and the locking component is used to fix the auxiliary wheel on the wheel hub of the wheel, so that the auxiliary wheel is driven by the wheel hub of the wheel. The present invention further relates to an unassisted lifting jack used when the auxiliary wheel is mounted. The unassisted lifting jack comprises a climbing block and a supporting block connected in a rotary way, the climbing block and the supporting block have a common supporting bottom, and the climbing block has a slope provided to the auxiliary wheel for climbing.
