Abstract

The invention relates to an auxiliary device for spare tire dismounting. The auxiliary device is characterized by comprising a connection ring, support frames and foot wheels, wherein the the connection ring is embedded into a flange groove of a spare tire steel rim, a broken opening is formed in the connection ring, and two ends of the broken opening are connected by a spreading adjustment mechanism; at least three support frames are mounted on the connection ring, the upper parts of the support frames jack in corresponding positioning parts of the spare tire steel rim, and the foot wheels are mounted at the bottoms of the support frames. According to the auxiliary device for spare tire dismounting, the structure is simple, the design is reasonable, a spare tire can be pulled from a vehicle bottom easily when the spare tire falls on the floor, and the operation is convenient and safe.

Description

technical field [0001] The invention relates to an auxiliary device for disassembling a spare tire, belonging to the technical field of automobile parts. Background technique [0002] In the event of a tire blowout, the spare tire needs to be disassembled and replaced. For large cars, the spare tire is very heavy and it is very troublesome to disassemble. When disassembling, the spare tire needs to be tightened and loosened first, and then the spare tire is moved by the rocker arm. Slowly lower it, and then manually pull the spare tire out from the bottom of the vehicle. Since the weight of the spare tire is generally hundreds of kilograms, this operation method is very laborious, it is difficult for one person to do it alone, and there is a certain degree of danger. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide an auxiliary device for dismantling a spare tire, which has a simple str...
