Air-free tire of replacing TPR (Thermo Plastic Rubber) material with air

Abstract

The invention discloses an air-free tire of replacing a TPR (Thermo Plastic Rubber) material with air, which is characterized by comprising a wheel outer tire (1), a wheel inner tire (2), a vacuum wheel tire (A1), a TPR material (3), an air nozzle (4) and a wheel rim (5), wherein the rigidity range of the TPR material can be selected according the size, the driving speed and the load of a vehicle; and an auxiliary member of the air-free tire of replacing the TPR material with air comprises a charging device, an inner thread air nozzle connecting sleeve (21), a circular base adjustable hook bracket, a tire pressure positioning and interrupting device, and the like. The TPR material is replaced with air to be charged into the wheel tire and has elasticity and shock absorption effects as same as air. The pressure of the charged TPR material is regulated according to the load and the required driving speed so as to reach a certain pressure for adapting to the requirement on the load of the vehicle. The tire is fearless of being pricked and can not be punctured after being cooled and cured as well as pressurized. The wheel tire always keeps equal pressure to ensure that the service life of an outer tire of the wheel is prolonged; and when the outer tire is worn seriously and can not be used, the charged TPR material can be fully recycled; meanwhile, the manufacture process of the tire is simple.

Description

technical field [0001] The invention belongs to a wheel tire of a vehicle --- an airless tire in which TPR material replaces air. Background technique [0002] At present, there are various designs for airless tires, but none of them can be accepted by people. Why? It is because there are more or less defects in these designs. For example: the characteristics of the Tweel wheel developed by Michelin (Michelin) are retro. Its shock-absorbing rubber wheel treads distribute pressure across dozens of resilient polyurethane spokes. These spokes are in turn supported by an aluminum mandrel. Because there is no gas in this wheel, it is stronger than a pneumatic tire and less prone to blowouts. The wheels have already been tested on the "iBOT3000 Independent Mobility System" (iBOT) robotic wheelchair and military vehicles. Michelin says the wheels are still too noisy to be used in cars right now. There are four applications for airless tires in the patent retrieval of the Stat...

AI Technical Summary

Problems solved by technology

There are many shortcomings in the design and manufacture of the above patents, the manufacturing is complicated and the cost is high, and of course the shock absorption effect will not be good, etc.

The advantages and disadvantages of pneumatic tires coexist, which brings convenience to our transportation, but also brings great danger to our personal safety and great economic losses.
