Description

Novel inflation-free tire

Technical Field

The utility model relates to an exempt from pneumatic tire equipment technical field, concretely relates to novel exempt from pneumatic tire.

Background

A tire is a ground-rolling circular ring-shaped elastic rubber article mounted on various vehicles or machines. The tires for electric vehicles and motorcycles, i.e. the tires applied to electric vehicles and motorcycles, are usually inflatable tires, and are developed into vacuum tires at present, and the tires have excellent performance, but have obvious defects, are easy to puncture and burst, and have low bearing capacity.

In order to avoid the phenomenon of tire burst, an inflation-free solid tire is introduced on the market, but when the tire is connected with a hub, the contact effect is poor, and the following points are mainly shown:

1. the connection effect of tire and wheel hub is poor, can appear the phenomenon of aversion, and the aversion also is the phenomenon that appears skidding between tire and the wheel hub, can cause serious potential safety hazard when the tire appears the aversion.

2. When turning round, because electric motor car motorcycle when turning round, the tire can incline, and traditional inflation-free tire height is higher can receive the ground to the reaction force of tire when turning round, leads to the tire to take off the circle easily, can cause very serious potential safety hazard equally.

3. The traditional solid tire has poor damping effect because the traditional solid tire adopts polyurethane as a foaming material, and the polyurethane foaming material has poor damping effect, so that the damping effect of the tire is poor.

Therefore, a novel non-pneumatic tire is provided.
