Embodiment 1

[0017] Embodiment 1: as figure 1 As shown, the automobile plastic spare tire includes a plastic hub 1, the plastic hub 1 is provided with a spare tire mounting hole 2, and a circle of plastic elastomer 3 is provided on the plastic hub 1 outer periphery. This design has a simple structure and does not need to be inflated; secondly, the weight is reduced, which improves the fuel economy of the car. Taking an ordinary car as an example, an ordinary spare tire weighs about 20kg. After changing to a plastic spare tire, it can reduce about 10kg, which can Improve the fuel economy index by about 0.7%. In addition, compared with ordinary rubber spare tire materials, plastic materials can be reused and environmentally friendly; in addition, the price is lower.

[0018] The plastic hub 1 and the plastic elastomer 3 are integrated, so designed, it is easy to process and improve the convenience of use; the outer circumference of the plastic hub 1 is provided with a U-shaped groove 4, and ...

Abstract

The invention relates to an automobile plastic spare tire. The weight of the existing automobile spare tire is heavy and no good is done to automobile fuel economy; and besides, since most automobile spare tires are made of rubber, steel or aluminum, the structure is complex, the rubber cannot be easily reused and the requirement on environmental friendliness is not satisfied. Accordingly, the automobile plastic spare tire comprises a plastic wheel hub. Spare tire installation holes are arranged in the plastic wheel hub. A circle of plastic elastomer is arranged on the periphery of the plastic wheel hub. The plastic wheel hub and the plastic elastomer are in an integral body. A circle of U-shaped groove is arranged on the periphery of the plastic wheel hub. The plastic elastomer is fixedly arranged on the U-shaped groove. The two vertical sides of the U-shaped groove are transitioned through external round corners. The automobile plastic spare tire provided by the invention has a simple structure and is scientifically designed, and has the advantages that the spare tire is not required to be inflated, the cost is low and the like; moreover, the weight is reduced and the automobile fuel economy is improved; and compared with common rubber spare tires, the automobile plastic spare tire provided by the invention has the advantages that since plastic materials are used, the reuse can be realized and the spare tire is environment-friendly.

Description

technical field [0001] The invention relates to an automobile spare tire, in particular to an automobile plastic spare tire. Background technique [0002] Spare tires have existed for more than 100 years. The earlier tire manufacturing technology was immature, the tire quality was not good enough, and the road was uneven. The spare tire was an essential equipment. With the rapid development of tire technology, most tires have evolved into tubeless radial tires. At the same time, the improvement of roads has also greatly extended the life of tires, so that the utilization rate of spare tires has been continuously reduced; coupled with the continuous increase of car maintenance outlets, Car maintenance has become very convenient. Therefore, the requirements for car spare tires are getting lower and lower. Some car manufacturers only equip spare tires that are narrower than the original car model, and stipulate that "after replacing the spare tire, the driving speed shall not ...
