Abstract

The invention relates to an auxiliary device for mounting of a spare tire for trucks or large and medium buses and belongs to an auxiliary tool for automobiles. The auxiliary device for mounting of the spare tire comprises a rack bottom frame, wherein universal wheels are arranged at corners of the rack bottom frame, a vertical frame is upwards vertically arranged on the rack bottom frame, a lifting mechanism is arranged on the vertical frame, a supporting shovel used for supporting the tire is connected with the lifting mechanism and supports the tire surface of the spare tire, the lifting mechanism performs a lifting action to raise the supporting shovel, and then the spare tire rises together with the supporting shovel, so that the spare tire is not required to be carried and lifted manually, a person is only required to observe the height and the left-and-right position of the spare tire and conveniently insert the spare tire in the position of a connected bolt, a nut is screwed up, and the tire can be changed conveniently. With the adoption of the auxiliary device, the labor intensity of manual tire changing is greatly reduced, and a lot of time can be saved.

Description

technical field [0001] The invention relates to a spare tire installation auxiliary device for trucks or large and medium-sized passenger cars, which belongs to auxiliary tools for automobiles. Background technique [0002] A heavy-duty truck or a large and medium-sized passenger vehicle is a vehicle designed mainly for carrying goods or passengers. For example, a heavy-duty truck has always played an important role in the national logistics and transportation process. During frequent transportation, heavy-duty trucks often have tire blowouts due to various reasons. For light vehicles such as cars, it is not difficult to replace the spare tire, but for medium-sized or even heavy-duty trucks or large and medium-sized passenger cars, because the diameter of the rim of the spare tire of a medium-sized truck is usually larger, the dead weight generally exceeds 50kg. Therefore, manually carrying and installing the spare tire is not only time-consuming and laborious, but even nee...

AI Technical Summary

Problems solved by technology

Therefore, it is not only time-consuming and labor-intensive to carry and install the spare tire manually, but even requires more than two people to replace it.

Due to the heavy weight of the spare tire, most of the time is wasted in moving the spare tire and aligning it during the tire replacement process.

Handling the spare tire manually is not only time-consuming and labor-intensive, but the spare tire may also be reversed and dropped during transportation, which not only affects the handling time, but may even injure the driver and cause potential safety hazards
