Non-pneumatic tire and tire working method based on negative Poisson's ratio structure

Abstract

The invention provides a non-pneumatic wheel based on a negative Poisson's ratio structure, which includes a hub, a negative Poisson's ratio support body and an outer tread. The negative Poisson's ratio support body is installed around the outside of the hub, and the outer tread is installed around the outside of the negative Poisson's ratio support body. The wheel hub adopts a flat-bottom rim, the spokes and mounting holes are the same as the existing wheel hub, the negative Poisson's ratio support body has elastic deformation capability, the outer tread adopts low rolling resistance rubber, and the tread has patterns that increase friction. The technical scheme of the present invention uses a negative Poisson's ratio support body to replace the pneumatic tire part, which can not only play a supporting role, but also meet the requirements of vibration reduction and energy absorption, and reduce the overall quality of the wheel, ensuring the ride comfort of the car, and has a simple structure , easy to manufacture.

Description

technical field [0001] The invention belongs to the field of wheels, and in particular relates to a non-pneumatic tire based on a negative Poisson's ratio structure and a tire working method. Background technique [0002] At present, the pneumatic tires on the market are rubber-enclosed and pressurized air. When the air is compressed, the impact of the air molecules on the container wall is more intense, and the air tires are easily stimulated by sharp objects and are prone to tire bursts. Therefore, based on the consideration of safety performance, non-pneumatic tires came into being. It uses the material and structure of the tire itself to achieve support and cushioning. Compared with pneumatic tires, non-pneumatic tires have the advantages of maintenance-free and puncture-free. [0003] At present, there are two main types of non-pneumatic tires on the market. One is rubber solid tires, which have a production history of hundreds of years, but their limitations are also o...

Problems solved by technology

[0003] At present, there are two main types of non-pneumatic tires on the market. One is rubber solid tires, which have a production history of hundreds of years, but their limitations are also obvious. The weight of the carcass is large, the elasticity is poor, and the rolling resistance is large. low-speed heavy-duty vehicles

The other is a wheel with elastic deformation as a structural support body. The TWEEL launched by Michelin in France and the Terra in Armor launched by Polaris in the United States are representative products, but they are expensive and cannot be mass-produced
