Description
Technical field
The utility model belongs to motor tire, is specifically related to a kind of secondary tire and uses the safety tyre of this pair tire.
Background technology
Automobile flat tire is very serious safety misadventure, particularly blows out at express highway, and the centre-of gravity shift of moment makes to lose control of one's vehicle possibly, causes the generation of grave accident.According to statistics, the unexpected traffic accident of China's express highway 70% causes by blowing out.
Automobile has more and more driven into the common people's life as a kind of walking-replacing tool, and as the private car car owner, women car owner particularly in case tire occurs losing heart and needs to change when automobile is set out on a journey, will be a very thing of difficulty trouble.
If therefore vehicle still can the certain distance of cruising arrive repair plant after tire loses heart, just can farthest solve above-mentioned worrying safety problem.
The technology that is used for motor tire Runflat aspect at present is a lot, as being that representative discloses a kind of automobile leakproof safety wheel and tire with Chinese patent 200420016192.7, the periphery fixed cover of the bead seat of its wheel rim be equipped be positioned at vacuum tyre, lose heart or its still walking ring skeleton is supported in blast when vacuum tyre.This technical security poor reliability, the yielding damage of embedding structure when tire is hit is unfavorable for during tyre service that the workman operates.
The utility model content
The purpose of this utility model is to provide a kind of secondary tire and safety tyre, this tire lose heart or blow out after can guarantee that still vehicle drives at moderate speed, safe and reliable and convenient maintenance and replacement.
Secondary tire of the present utility model has an annular inflatable tire, and the outer ring of air tyre is the supporter of thickening, and inflatable inner tube is provided with tire tube valve, and the outside of supporter is provided with air channel.
Secondary tire of the present utility model also can be made up of the supporter of annular inflatable tire and ring-type independently, and the both sides of supporter are provided with the shoulder muscle that forms groove, and air tyre can place in the groove that is formed by the shoulder muscle on the supporter.
Secondary tire of the present utility model also can be, comprises the supporter of annular inflatable tire and ring-type, and the both sides of supporter are provided with the shoulder muscle that forms groove, and air tyre places in the groove that is formed by the shoulder muscle on the supporter, and the outer ring and the supporter of air tyre connect as one.
Safety tyre of the present utility model comprises wheel hub and is fixed on cover tire on the wheel hub, the bead seat of wheel hub is provided with the throttle mouth, periphery at the bead seat of wheel hub is fixed with described secondary tire, the air tyre of secondary tire can be fitted with the periphery of bead seat, form inflating cavity between the supporter of secondary tire and the cover tire, the tire tube valve of inflatable inner tube is protruding from the bead seat of wheel hub, and the head of described throttle mouth is provided with the pore of side direction.
Can establish antipricking layer in the above-mentioned supporter.
After secondary tire was contained in the safety tyre, inflation can extraordinaryly be fitted on the periphery of wheel hub bead seat injustice to air tyre, and secondary tire is fixed on the wheel hub firmly, has steadiness preferably, and increases its bearing capacity and adhere to torsion.When tire leaks air or blow out situation, can utilize the supporting role of secondary tire supporter during driving, still can keep vehicle to drive at moderate speed.When needing to change tire, only need the gas of air tyre is just bled off and cover tire, secondary tire can be taken out simultaneously.The shoulder muscle and the air tyre of supporter together play the dual support effect to cover tire.Air channel on the outside of supporter can form gas channel between cover tire and secondary tire, making the throttle mouth from the wheel hub bead seat can normally be the cover tire inflation.Antipricking layer in the supporter can prevent that foreign matter is with interior puncture.Safety tyre with said structure makes that driving is more safe and reliable, uses and keeps in repair also very convenient.
The utility model also has following characteristics:
1, simple in structure, demolition, installation are convenient, and the factory that do not need repairing increases new tyre dismounting equipment;
2, safe and reliable, the vehicle that the accessory whorl tire has been installed can ensure the tire Runflat, even long-term or run at high speed, does not also have ill-effect.The accessory whorl tire has shock resistance, can not keep the high fine balance of wheel because of the phenomenon in heavy burden or foreign impacts generation skew axle center;
3, because of the accessory whorl tire is empty little in taking, and certain space is arranged between supporter and the tire, tire pressure remains in the normal value, therefore can not influence the original traveling comfort of vehicle;
4, price is easy to customer's acceptance, has equipped the accessory whorl tire, and vehicle can be equipped spare tyre, has both saved vehicle space, has saved expense again.
Below in conjunction with drawings and Examples the utility model is further specified.
