Abstract

In the present invention, the passenger car is impossible to operate due to tire punctures and abnormalities during operation, or the road becomes an icy road due to winter snow, and thus all passenger cars are replaced in order to replace it in a safe operation due to tire slip of the passenger car. This is about the loading of secondary tires and snow chains.
Auxiliary tires and snow chains that are usually loaded in a passenger car for emergency use, because the weight of the tire itself is heavy, there is a problem in the fuel economy of the passenger car, in particular, the replacement of tires due to the puncture of the tire while the female driver driving, or slipping in winter Installation of snow chains is not easy to prevent. In order to facilitate this problem, the center axis of the independent wheel frame is made so that the center axis of the wheel frame of the new auxiliary tire can be moved up and down. Instead of separating the flat tire from the passenger car, the center axis of the wheel frame of the flat tire and the center axis of the wheel frame of the new auxiliary tire are variably moved to adjust the height so that the center axis and the central axis coincide with each other. Attach a new auxiliary tire to the outside of the flat tire. When the central axis of the new auxiliary tire wheel frame is attached to the outside of the flat tire wheel frame central axis, move the central axis of the new auxiliary tire to the center of the wheel frame of the new auxiliary tire, and then move the central axis to the auxiliary tire. Fully secured to the wheel frame. When the central axis of the new auxiliary tire is completely fixed to the center of the wheel frame, the passenger car is balanced by the new auxiliary tire and the passenger car can be safely operated to the place where the tire repair shop is located. If slippage occurs due to ice caused by snow in winter, and the safety operation of the passenger car is affected, the snow chain made for the new auxiliary tire is mounted in the snow chain mounting hole of the new auxiliary tire, and then By attaching a new auxiliary tire equipped with a snow chain to the left and right outer sides of the driving tire of the passenger car, it is possible to drive safely even on an icy road.
The new auxiliary tire having such a structure is a matter related to a new concept of a new auxiliary tire that can be easily worn by a woman since the tire can be attached to the outer side of the existing tire without separating the existing tire when punctured.

According to the present invention, in a spare tire, the tire mounted on the passenger car needs to be replaced due to an abnormality such as puncture while driving or parking, or the road is slippery due to winter snow, so that the snow chain should be attached to the driving tire of the passenger car. It is a new auxiliary tire that can be used.

Existing spare tires have to be lifted by a small car when the tires mounted on the passenger car are damaged due to puncture, etc. After removing the abnormal tires completely from the passenger car, the existing auxiliary tires must be replaced. When it snows, the road is slippery, and if the snow chain is attached to the drive tires mounted on the car, the snow chain is laid out on the floor of the road, and then the car is moved over the chain spread on the road. It will be mounted on it.

The present invention is to solve the difficulty of mounting as described above and to more easily mount a new auxiliary tire or snow chain, the central axis of the new auxiliary tire wheel frame, the wheel of the flat tire of the passenger car It is a new concept new auxiliary tire manufactured to be able to move up and down the central axis of the wheel frame of the new auxiliary tire so as to be moved to the same position as the central axis of the frame.

According to the present invention, the existing auxiliary tires and the non-slip snow chains for winter, which are loaded on the passenger car, also affect the fuel economy of the passenger car due to the weight of the auxiliary tires and the snow chain itself, and particularly when an abnormality occurs in the tire. Replacement of auxiliary tires and snow chain installation are not easy. Especially when the driver is female, the work is more difficult.

When the new auxiliary tire of the present invention is used, the tire is attached to the outer side of the existing tire, which is attached to the passenger's car, without detaching the existing tire, which is attached to the passenger car. Therefore, the driver can easily and quickly emergency tires of passenger cars with abnormalities.
