Description

Radial-dividing multi-cabin type slow-burst tire

Technical Field

The utility model relates to a motor vehicle accessory technical field particularly, relates to a radially cut apart many cabins formula and slowly burst tire.

Background

With the continuous increase of automobile reserves in the automobile society of China, disasters caused by tire burst in high-speed running of vehicles often see news, and cause irreparable loss of lives and properties of people. The reason is that once a conventional common vacuum tire is burst under a high-speed driving state due to various situations, the tire pressure is released instantly, the tire loses the support of the vehicle, and the change process is very fast and exceeds the reaction speed of a common driver, so that the vehicle is out of control and disasters occur. One of the ideas for solving the problem is to ensure that the tire maintains local tire burst or wholly presents a slow burst process when the tire is broken, so as to gain enough time and opportunity for the driver to react, control the vehicle and deal with accidents, thereby avoiding disasters.

Disclosure of Invention

At present, the solution of the problem of tire burst of automobiles is that a plurality of proposals of the suzuki is sufficient, but in the view of the proposals, firstly, in the concept, no proposal creatively provides a 'slow burst' idea for prolonging the tire burst process, and almost all the tyre is designed to be anti-burst, non-burst and run-flat, thereby leading to the following typical defects that ① is additionally provided with extremely complex structural components or parts on the basis of the traditional vacuum tyre, the production difficulty is large or even infeasible, the cost is high, the weight of the tyre is increased too much, the use experience is poor, ② does not consider enough maintainability and maintainability, and the great difficulty exists in normal deflation or normal maintenance of the tyre.

For example, the scheme of 'explosion-proof tire' (hereinafter referred to as 'comparison document') of publication No. CN103991334 and publication No. 2014.08.20 has the typical defects that ① automobile tire crown needs to be repaired if being nailed, and the comparison document is designed without removing heat and repairing patches and lacks the practicability of the invention, ② has the parallel partition 3, so that the operation space for installing or detaching the tire on or from a hub ring is reduced by half, the great operation difficulty is brought, the practicability of the invention is lacked, ③ parallel partition makes the weight of the whole tire more heavy, the material consumption and oil consumption are in disadvantage, the use experience difference is large, ④ parallel partition divides the divided outer layer to seal a tire body, the feasibility of processing and manufacturing is in doubt, a hole is directly arranged on each partition plate of ⑤ divided cabins to slowly release air pressure for explosion prevention, the slow-release effect of tire pressure of 0.2-0.3 MPa of the automobile is lacked with data support, the invention for high-pressure gas is obvious, the pressure release process is nonlinear, and the scheme of basically lacked in the practical support of the automobile body, and the scheme of the invention is created.

The design is to solve the problem of prolonging the tire pressure loss time and providing basic wheel support when the automobile runs at high speed and has a tire burst by an innovative, simple and ingenious idea so as to avoid tire burst accidents.

The utility model discloses a "slow explosion" effect when reaching the tire and bursting, the technical scheme that will adopt is: on the basis of the traditional vacuum tire, the inner part of the tire is uniformly divided into eight independent cabins by a rubber compartment plate along the radial direction; the root and two side edges of the compartment plate are respectively and tightly connected with a tire crown and two tire sides in the vacuum tire, the free end parts respectively extend out of tails (the two sides respectively extend for about 5 cm) towards the two sides in the circumferential direction, when the tire is installed on a wheel hub, the extending tails are tightly contacted with the inner side of the wheel hub, and the contact surface is coated with an interface agent for enhancing frictional contact and playing a role in sealing.

The rubber partition board is provided with a rubber vent pipe which is communicated with adjacent compartments, the inner diameter of the hole is about 3-5 mm, the total length is about 8cm, and the wall thickness and the material flexibility are determined according to specific tire specifications, related pressure parameters and the like; when the tire normally charges and discharges air through the air tap, because the two sides of each adjacent cabin have no pressure difference or the pressure difference is very small, each vent hole is kept smooth, and the uniform charging and discharging of the whole tire is met; when the tire bursts, the air pressure of the corresponding tire burst cabin is suddenly reduced, and huge pressure difference is generated between the corresponding tire burst cabin and the adjacent cabin instantaneously, so that the vent holes between the tire burst cabin and the adjacent cabin are flattened, the tire burst cabin is in a compression blocking state, meanwhile, the tail of the end part of the partition plate is compressed by the instantaneous pressure difference, the air pressure of the adjacent partition cabins on the two sides is blocked and delayed to be leaked rapidly, and the purpose of whole slow burst of the tire is achieved.

The technical scheme brings the following advantages: the utility model firstly only attaches eight subdivision rubber baffles with air vents on the basis of the traditional vacuum tire, has ingenious idea, simple structure, easy production, little cost and weight increase and almost consistent use experience compared with the traditional tire; secondly, the processes of maintaining, repairing and inflating and deflating the tire are basically the same as those of the traditional vacuum tire; most fundamentally, the original tire is instantaneously burst out of control, and is transformed into a slow burst process which lasts for more than 10s, so that precious time is gained for a driver to deal with conditions, and accidents are avoided.

Compared with the typical comparison scheme, the utility model completely overcomes the defects, has ingenious, novel, feasible, reliable and practical design, and belongs to the invention of 'element omission' in element change to a certain extent; especially, by utilizing physical skill, the hose is arranged on the hole of the partition plate, the effect of smooth and closed air hole is skillfully achieved by utilizing the pressure difference condition, the reasonable requirements in normal inflation, deflation and tire burst situations are met, and the effects of slow burst and disaster prevention of the tire are really achieved.
