Abstract
The utility model relates to a run-flat tire which comprises a hub and a tire body sleeving the hub, wherein an air faucet extending into the tire body is arranged on the hub, the tire body sequentially comprises an outer tire surface, an anti-explosion layer, a reinforcing layer and a tire body which are adhered into a whole from outside to inside, a plurality of elastic support bodies extending towards a circle center of the hub are uniformly arranged on the inner surface of the tire body along the circumference of the tire body, and a gap is reserved between the elastic support bodies and the hub. The run-flat tire is reasonable in structure design, and capable of preventing from being punctured by a sharp so as to avoid tire burst; even if the tire body is punctured to cause tire burst, the speed of outwards leaking gas in the tire body can be delayed so as to avoid the phenomenon that the running direction of an automobile is suddenly changed due to deflated tire within a short time and enough response time is provided for a driver to stabilize and stop the automobile, and thus the personal safety of the driver and passengers is effectively ensured.
Description
Technical field:
The utility model relates to a kind of trouble-proof tire.
Background technology:
At present, the tubeless design of the many employings of tire of using on automobile, chamber between wheel hub and tire body is as a whole, in the process that automobile is being run at high speed, when tire is pierced through by knife-edge and blows out, the supporting role that automobile loses tire causes wheel hub directly contact with ground and rub, because hub diameter is little more a lot of than diameter of tyres, automobile meeting flip-flop travel direction after blowing out, chaufeur is difficult to reacting in a flash of blowing out, very easily occur overturning or collision phenomenon, this will serious threat chaufeur and passenger's personal safety.
Utility model content:
The utility model provides a kind of trouble-proof tire, and its reasonable in design can prevent from being pierced through by knife-edge, avoids blowing out; Even if be pierced while blowing out, also can delay the interior gas of tire body to the speed of outward leakage, guaranteed tire can be not at short notice because of the travel direction of flat tire flip-flop automobile, give chaufeur with the sufficient reaction time, vehicle steadily is lived and stopped, thereby actv. has guaranteed chaufeur and passenger's personal safety, has solved problems of the prior art.
The utility model is to solve the problems of the technologies described above adopted technical scheme to be: it comprises wheel hub and is set in the tire body on wheel hub, on wheel hub, be provided with a valve that stretches into tire body, described tire body is followed successively by bonding all-in-one-piece tread, explosion-proof layer, strengthening course and carcass from outside to inner side, inside face at carcass is provided with along its even circumferential the elastic support that several extend to the wheel hub center of circle, between elastic support and wheel hub, is provided with gap.
Described explosion-proof layer is the folded explosion-proof layer that is affixed on one that aromatic poly amide interweaves and makes, and its Denier value through weft material is between 150D to 300D, and its density is between between 30EPI to 80EPI, and its folded paste layer number is more than three layers.
Described strengthening course is the folded strengthening course that is affixed on one that nylon fiber interweaves and makes, and its Denier value through weft material is between 210D to 1360D, and its density is between between 20EPI to 120EPI, and its folded paste layer number is more than one deck.
Described elastic support is rubber bodies.
The utility model adopts such scheme, and reasonable in design, can prevent from being pierced through by knife-edge, avoids blowing out; Even if be pierced while blowing out, also can delay the interior gas of tire body to the speed of outward leakage, guaranteed tire can be not at short notice because of the travel direction of flat tire flip-flop automobile, give chaufeur with the sufficient reaction time, vehicle steadily is lived and stopped, thereby actv. has guaranteed chaufeur and passenger's personal safety.
Simple in structure, save Material Cost, alleviate tire weight, thereby reduce oil consumption
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that in Fig. 1, A-A analyses and observe cross section structure schematic diagram.
In figure, 1, wheel hub, 2, tire body, 3, valve, 4, tread, 5, explosion-proof layer, 6, strengthening course, 7, carcass, 8, elastic support.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in Fig. 1～Fig. 2, the utility model comprises wheel hub 1 and is set in the tire body 2 on wheel hub 1, is provided with a valve 3 that stretches into tire body 2 on wheel hub 1.Tire body 2 is followed successively by bonding all-in-one-piece tread 4, explosion-proof layer 5, strengthening course 6 and carcass 7 from outside to inner side, inside face at carcass 7 is provided with along its even circumferential the elastic support 8 that several extend to wheel hub 1 center of circle, between elastic support 8 and wheel hub 1, is provided with gap.Elastic support 8 is rubber bodies.Carcass 7 is made for nylon or poly-ester fibres.The folded explosion-proof layer 5 that is affixed on one that explosion-proof layer 5 is made for aromatic poly amide interweaves, its Denier value through weft material is between 150D to 300D, its density is between between 30EPI to 80EPI, its folded paste layer number is more than three layers, can make explosion-proof layer 5 form a hard combination, can resist piercing through of external knife-edge.The folded strengthening course 6 that is affixed on one that strengthening course 6 is made for nylon fiber interweaves, be positioned at explosion-proof layer 5 inner sides, its Denier value through weft material is between 210D to 1360D, its density is between between 20EPI to 120EPI, its folded paste layer number is more than one deck, can strengthen rigidity, tackness and the bearing force of explosion-proof layer 5.Explosion-proof layer 5 after dip treating, then with tread 4 with carcass 7 is bonding forms, utilizes the anti-puncture of explosion-proof layer 5 and the strengthening of strengthening course 6 with strengthening course 6, makes tire body 2 reach the effect that runs over knife-edge and be not pierced.
When tire body 2 is pressed onto shorter knife-edge, its knife-edge can insert tread 4, can not be inserted into explosion-proof layer 5, the phenomenon that therefore can not blow out, when tire body 2 is pressed onto longer knife-edge, its knife-edge can insert explosion-proof layer 5 or strengthening course 6, utilizes the anti-puncture of explosion-proof layer 5 and the strengthening of strengthening course 6, makes tire body 2 directly press knife-edge, make knife-edge fracture or crooked, the phenomenon of therefore also can not blowing out, when the knife-edge that tire body 2 is pressed onto longer, when harder, knife-edge can pierce through carcass 7, gas can outwards spill from tire body 2, at this moment the elastic support 8 of tire body 2 gas leakage point both sides connects with wheel hub 1, be equivalent to block the gas leakage point on tire body 2, thereby blocked leaking of gas, simultaneously under the cooperation of elastic support 8 supporting roles, guaranteed tire can be not at short notice because of the travel direction of flat tire flip-flop automobile, give chaufeur with the sufficient reaction time, vehicle steadily is lived and stopped, thereby actv. has guaranteed chaufeur and passenger's personal safety.It is to the structure of outward leakage, reasonable in design, simple and practical that the utility model delays in tire body gas when blowing out, and saved Material Cost, alleviated tire weight, can reduce oil consumption.
The above-mentioned specific embodiment can not be as the restriction to the utility model protection domain, and for those skilled in the art, any alternate modification that the utility model embodiment is made or conversion all drop in protection domain of the present utility model.
The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
