Description
Technical Field
The invention relates to the technical field of tires, in particular to an open-structure tire.
Background
Currently, the tires in use worldwide are not classified into two types, i.e., pneumatic tires and non-pneumatic tires, and the non-pneumatic tires include two types, i.e., open structural tires and solid tires. All kinds of tires are good and bad in the aspect of respective specific use environment and requirements, but all the tires face a common problem that no effective solution exists until now, namely, all the tires influence comfort, handling and safety when the load bearing of the tires is changed, and the tires are heavy duty tires and power tires.
In particular, tires of all kinds are known, the load of which is positively correlated with the compression of the tire. When the bearing capacity is too light, the deformation of the tire is reduced, the comfort level is reduced, the contact between the tire surface and the ground is reduced, the grip of the tire is weakened, and the braking distance is prolonged; when the bearing is too big, tire deformation increases, because of the suspension system pressurized of its vehicle, and the same comfort level reduces, and the tread is the increase trend with the contact on ground, and tire grip is too strong, and wearing and tearing, control dynamics and energy consumption increase, and the probability of blowing out rises simultaneously. The solid tire has the performance that the internal heat is increased sharply, and even the tire is exploded. The load bearing, comfort and controllability of the vehicle can be harmonious and unified only when the load bearing of the vehicle and the deformation of the tires reach an ideal balanced state, and the ideal condition is less under the normal use condition of the vehicle, and the vehicle working in most of the time is used under the non-ideal state.
Take a bicycle tire as an example. Under the normal inflation state, if one to several people or heavier goods are loaded, the loaded mass is multiplied by several times compared with the self mass of the bicycle, the deformation of the tire is increased, the riding resistance is increased, the control is difficult, and the abrasion of the tire is increased. To combat this situation, the tire pressure must be increased and the negative effects reduced. When the air pressure of the tire is increased, the bicycle ridden by a single person or a lighter load becomes jolt, the ground contact area of the tire surface is reduced, the grip force is reduced, the bicycle is easy to slip on particularly wet and slippery road surfaces, the braking distance is correspondingly prolonged, and meanwhile, the tire burst probability is increased. Of course, in a run-out condition below the normal inflation pressure, the negative effects of normal or increased load will increase dramatically, as will the chance of a tire burst.
The case of a non-pneumatic tire is similar except that the hardness of the carcass material is similar to the inflation pressure of the pneumatic tire. Although there is no risk of tire burst, excessive deformation of the non-pneumatic tire increases fatigue and internal heat generation of the tire body material, and the probability of tire damage is greatly increased.
Based on above drawback, improve current tire structure, make its travelling comfort, nature controlled and security reach harmonious unity when the bearing changes, be the problem that the present stage urgently need to be solved.
