Description

a non-pneumatic tire

technical field

The utility model relates to the field of automobile tires, in particular to a non-pneumatic tire.

Background technique

At present, the commonly used automobile tires are mainly pneumatic tires, which fill compressed air into the elastic bag to alleviate the vibration and impact during exercise. This tire often needs to inflate, change tires and repair tires because of easy air leakage and blasting in application, which brings many inconveniences to people's production and life.

In addition, if a tire blows out at high speed, it is very dangerous and often leads to serious traffic accidents. Because the vehicle is running fast on the highway, the continuous friction will increase the surface temperature of the tire and the air pressure inside the tire. For "healthy" tires, the increase in temperature and pressure can be overcome, but for the occurrence of Tires that are excessively worn or have obvious trauma or scratches are difficult to withstand huge pressure, so the probability of tire "accidents" is higher. According to statistics, 70% of my country's expressway traffic accidents are related to tires, and car blowouts have really become "super killers" on expressways.

Many scientific research and production departments at home and abroad have invested a lot of manpower, financial resources, and material resources to try to solve the problems of tires without inflation and safety. At present, many new types of non-pneumatic tires have come out. Non-pneumatic safety tires mainly include: PU non-pneumatic tires, solid tires, non-pneumatic honeycomb tires, non-pneumatic resin spoke tires and Goodyear spring tires. Since the non-pneumatic tire adopts a non-inflatable structure, there are no problems such as puncture and damage of the existing pneumatic tire, which greatly increases the safety of the vehicle at high speed.

However, when the existing non-pneumatic tires are loaded, the spokes transmit impacts in a straight line relative to the road surface, and the spokes support the tread in a discontinuous interval, so periodic noise and vibration will be generated during driving. In addition, the spokes of the existing non-pneumatic tires are exposed. During driving, debris such as stones, mud, ice and snow are easily involved in the spokes of the wheels, resulting in uneven weight and unbalanced conditions of the wheels.

Therefore, it is very important to develop non-pneumatic tires that improve tire performance and ride comfort, and reduce driving noise and vibration.

Utility model content

The utility model proposes a non-pneumatic tire to solve the problems in the prior art, and the non-pneumatic tire has the advantages of reducing driving noise and vibration.

The beneficial technical effect of the utility model is:

1. The spoke blades are curved. When the tire is under load, the spoke blades in the tire contact area will bend in the same direction under the action of pressure, and there will be no relative bending of two adjacent spoke blades, which will cause the two spoke blades to bend. Contact wear; the elastic curved spoke blades act like compressed springs to better support the tread; when the tire is squeezed by the road, the curved spoke blades will have greater resilience, and it will Convert the elastic potential energy stored in the wheel into forward kinetic energy, which can save energy and reduce consumption.

2. The utility model is provided with sidewalls, which can prevent stones, mud, ice and snow and other sundries from being involved in the spokes of the wheels during the driving process of the car, resulting in uneven weight and unbalanced situation of the wheels.

3. The spoke blades are arranged obliquely relative to the inner peripheral surface of the outer cylinder and the outer peripheral surface of the above-mentioned inner cylinder. The inclined setting can make the connection area between the spoke blades and the inner peripheral surface of the outer cylinder and the outer peripheral surface of the inner cylinder larger, and enhance the connection strength between them; in addition, because the elastic spoke blades are curved, the bearing capacity Under the pressure, it will increase the support force of the tread, and then enhance the rigidity of the tread, so that the contact area of the tread and the ground contact more evenly when the tire is loaded.

4. The spokes in the utility model include several spoke blades including several long spoke blades and several short spoke blades, and the long spoke blades and short spoke blades are arranged at intervals, and the end of the long spoke blades located on the inside of the tire crosses the tire The central symmetry plane, and the inclination angles of the long spoke blades and the short spoke blades to the axis direction of the spokes are different. One end of the long-spoke blade crosses the central symmetrical plane of the tire, so that when the tire is on the ground and rolls under load, the long-spoke blade and the short-spoke blade together provide continuous and uninterrupted support for the tread. Long-spoke blades and short-spoke blades are arranged at intervals. First, the total length and total weight of the spokes can be reduced, that is, the weight of the tire (lightweight); second, the thickness, length and inclination angle of the short-spoke blades can be adjusted flexibly. The longitudinal rigidity and lateral rigidity of the tire can not only ensure the comfort of driving, but also ensure the stability of handling.
