Abstract
The utility model discloses a run-flat safety tire, in particular to a run-flat safety tire for cars. The run-flat safety tire is safe and reliable, various in specification and low in cost and comprises a side wall and a crown, wherein a lining block is fixedly mounted between the crown and a tire rim. After the lining block is arranged in a general tire, the lining block can bear load when the tire is burst on any conditions, and then the diameter and the circumference of the tire can not be changed obviously, thereby preventing accidents. The lining block can be designed into different specifications according to different conditions so as to meet requirements of different car models, and has low cost, and then the tire is not only safe but also economical and adaptive.
Description
Technical field
The utility model relates to a kind of run-flat safety tyre of run-flat safety tyre, especially automotive use.
Background technology
In present according to statistics China express highway, the traffic accident that causes owing to blowing out has accounted for more than 30% of the accidents caused sum of accidental cause, and blowing out becomes the major cause of traffic accidents.In order to guarantee the safe handling of tire, corresponding regulation has all been made by a lot of countries, indicate " DOT " peaceful up-to-standard sign in the tire side as the U.S., " DOT " is the abbreviation of US Department of Transportation, its subordinate's highway safety mechanism (Fwvss) stipulates corresponding safety rate at self-propelled vehicle, wherein the Fwvss-109 standard pin is to passenger car tire, and the Fwvss-119 standard pin is to heavy duty tire.Frankly speaking, this standard has only solved the quality problems of tire in manufacturing process.The tire build guality is no doubt important, but can't resolve the sudden accident that running at high speed blows out causes, the caused particularly serious traffic accident of particularly blowing out when running at high speed.
In order to solve the accidents caused problem of tyre explosion, saying should be to solve tire exactly
Blow out and normal tire circumference and radius do not wait the problem that causes the accident generation, U.S. Goodyear Tire and Rubber has released run-flat tire.Tire that still can safety traffic after promptly blowing out, after in fact all tire was blown out, the girth of left and right tire and radius waited scarcely, therefore, also can only drive to the tyre service shop and repaired to be lower than high-revolving conventional speeds.The principle of run-flat tire is: fill particular matter heat-resisting and that antifatigue is high on the sidewall of tire, these materials are by self the crooked bounce decomposition car weight pressure that produces, even having had gas fully, tire can not help tire to support the vehicle weight of 1/3-1/4 yet, these materials can extend to wheel rim and tire interlock place locks tire on wheel rim, its pressure and resistance to effect of heat have avoided follow-up the continuing of tire flat to sail and be destroyed in high temperature, therefore, Gu special deficency tire can not show the state of conventional tire deficency.Because run-flat tire costs an arm and a leg, be the conventional tyre valency 3-4 doubly and specification few, selection face is narrow, only is applicable to that only a few luxury car uses, and uses and be suitable for general vehicle.
The utility model content
Technical problem to be solved in the utility model provides a kind of safe and reliable, multi-size, run-flat safety tyre with low cost.
The run-flat safety tyre that its technical matters that solves the utility model adopts comprises sidewall and crown, it is characterized in that: be mounted with interior pad between crown and the wheel rim.
Further be, interior pad has 2 and along the tire circumferential arrangement at least, adjacent in the rear end and the front end of pad circumferentially interconnect, and interior pad outside face is close to the crown inboard.
On the basis of technique scheme, pad is circular-arc in can being provided with, and interior pad rear end is concavity, and interior pad front end is convex, and described convex and concavity are suitable.
Further be that interior pad rear end is connected by connecting pin with adjacent interior pad front end.
Further be to be provided with compression spring between interior pad and the wheel rim.
As the further improvement of above technical scheme, spring is a cone-shaped spring, and its major part be contained in in the blind hole on the pad, the microcephaly is connected on the wheel rim cylindrical.
As the further improvement of above technical scheme, interior pad can be set to 5-8.
As the further improvement of above technical scheme, the inboard faying face with interior pad cylindrical of tyre crown is provided with unvulcanized rubber or bridging particle.
Therefore the beneficial effects of the utility model are: interior pad is set in conventional tyre, makes no matter tire blows out, and all can support vehicle weight by interior pad under which kind of situation, can diameter of tyres not take place and perimeter change is excessive, prevent the generation of accident thus.Interior pad can adopt the material of endurance, resistance to compression, light weight, and is designed to different size according to different situations, can satisfy the needs of different automobile types thus, and with low cost, makes both safety of tire, and is economic and practical again.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1, Fig. 2, shown in Figure 5, the utility model comprises sidewall 3 and crown 11, pad 5 in being mounted with between the crown 11 of inside tires and wheel rim 1.Under cruising, interior pad 5 can not exert an influence to the running of tire.After blowing out, interior pad 5 is supported on and plays the effect that is similar to solid tyre on the wheel rim 1, make the minimizing that diameter of tyres can be not excessive, avoid generation, the traffic safety after therefore can actv. guaranteeing to blow out owing to accidents such as the excessive sideslip that causes of diameter difference between tire, rollovers.
On the basis of above technical measures, the traveling comfort of installing for convenience and not influencing tire 3 operations and running car, as shown in Figure 2, pad 5 has 2 at least in described, interior pad rear end 8 circumferentially interconnects with adjacent interior pad front end 6, and interior pad 5 outside faces are close to crown 3 inboards.Pad 5 only is equivalent to increase the wall thickness of tire in this moment, so can the performance of tire not exerted an influence.
On the basis of above technical measures, as shown in Figure 3, Figure 4, for the ease of the installation and the increase connection reliability of interior pad 5, pad 5 is circular-arc in described, interior pad rear end 8 is concavity, and interior pad front end 6 is convex, and described convex and concavity are suitable.
For the connection reliability between the pad 5 in further improving, as Fig. 1, Fig. 2, shown in Figure 5, described in pad rear end 8 be connected by connecting pin 4 with adjacent interior pad front end 6.
As shown in Figure 1 and Figure 2, for pad 5 in making can better be adjacent to tire 3 crown inboards, can between interior pad 5 and wheel rim 1, be provided with compression spring 2.
As shown in Figure 1 and Figure 2, for make spring 2 better be fixed on the pad, be unlikely to come off, spring 2 can be selected cone-shaped spring for use, and its major part be contained in in the blind hole 9 on the pad 5, the microcephaly is on wheel rim 1 cylindrical.
As shown in Figure 1, for the processing of pad in making, easy for installation, interior pad 5 is set to 5-8, is preferably 6 or 8.
For pad 5 in making can be more firm be adjacent to crown 11 inboards, and can be produced certain sealing function by damaged rear inner lining piece 5 at tire, can unvulcanized rubber or bridging particle be set at the faying faces of crown 11 inboards and interior pad 5 cylindricals.
Embodiment:
A, tire is done safety inspection.
B, the tire one side wheel rim 1 of packing into, tire below one side is in inboard, wheel rim 1 top, adds mat below tire, the convenient installation.
C, elder generation put into tire with two interior pads 5, wear connecting pin 4.
D, successively 5, five connecting pins 4 of other four interior pads are installed, check confirm after, the mat that takes out below the tire makes tire parallel with wheel rim 1.
E, spring 2 major parts are packed in blind hole 9 in the middle of pad 5 inner arcs, the microcephaly is on wheel rim 1 cylindrical.
F, tire is unkitted the side wheel rim 1 of packing into.
