Abstract
The utility model relates to a punctureproof wheel for motor vehicles, which is composed of a wheel hub and a tyre. The utility model has the improvement that a wheel rim of the wheel hub is provided with an installing groove structure; a miniature thick-wall inner tyre is prepared; an inner circle of the tyre is designed with an installing skirt; the installing skirt of the thick-wall inner tyre is installed in the installing groove of the wheel rim of the wheel hub and is fixed. The utility model can ensure that even when the air pressure of the tyre is zero, the tyre can not come off from the wheel rim. The utility model prevents the tyre exploding up to the hilt and ensures the driving safety.
Description
The utility model relates to auto-industry, is a kind of burst-proof tyre that is used on the power actuated vehicle.
Wheel is the rotary components that bears load between tire and axletree, general wheel is made up of wheel hub and tire two parts, along with improving constantly of the speed of a motor vehicle, and tubeless tires is universal, people require increasingly stringent to the safety performance of wheel, thereby make aluminium alloy wheel hub replace the steel wheel hub to become the trend of auto trade development.
At present, the generally equipped inner tube free radial-ply tyre of aluminum-alloy wheel, wheel rim for adapted inner tube free radial-ply tyre, its bead seat must adopt safe bead seat peak frame, to guarantee that under lower tire pressure bead seat peak frame can withstand tyre bead tire toe, stop tyre bead to slip into rim gutter, prevent that tire from coming off from wheel rim, have an accident avoiding.Facts have proved that these peak framves have played the sidewise restraint effect really, have guaranteed certain driving safety when tire is punctured gas leakage suddenly.But when tire pressure was very low, these peak framves just can not play the effect of contraction of side direction.
In order to overcome the above problems, external many research institutions have developed multiple run flat tire, in fact are exactly the reinforced bead sidewise restraint, even when tire pressure is very low, tyre bead can not slip into rim gutter yet, to guarantee traffic safety.
But there is following defective in above run flat tire:
1. the safety performance of run flat tire still has wretched insufficiency, this system can only guarantee can travel when air pressure is not enough, promptly when outer tire is punctured, slowly gas leakage, and rely on the pressure of inside tire to continue to travel, but seriously collide (promptly work as appearance and collide, under the situations such as strikes obstacles) when wheel occurring, wheel rim breaks, and causes the tire internal gas pressure to be reduced to 0 (in one minute) tyre bead rapidly and will slip into rim gutter; At this moment, the run flat system will be ineffective fully, when particularly occurring in wheel flutter.Can cause steering swivel system entirely ineffective, major accident takes place.
2. the run flat tire is because of inside and outside two-layer tire, thereby causes the wheel cost to rise, and particularly quality increases, according to evidence, and the every increase of wheel 1KG, then 1 liter of gasoline travels 0.8 kilometer at least, and its economical disadvantages is apparent.
3. the run flat tire need use specialized equipment to produce tire, and its price is expensive, and maintenance difficult when a damaged tyres, if there is not spare part of the same type, then can't be changed, and automobile can't travel, and influences service efficiency.
The purpose of this utility model is that a kind of fool proof failure-free new type explosion proof wheel will be provided, even it can guarantee that tire when air pressure is zero, still can not come off from the wheel rim of wheel hub, to guarantee traffic safety.
Concrete scheme of the present utility model is: burst-proof tyre has wheel hub and tire equally, particularly on the wheel rim of wheel hub, be shaped on the mounting groove structure, set up a small-sized heavy wall inner tube of a tyre, circle is gone up design in its tire the installation skirt, the installation skirt of the heavy wall inner tube of a tyre is gone in the wheel rim mounting groove of wheel hub and is fixed.
For simplifying technology, equipment, the mounting groove structure on the wheel rim of the utility model wheel hub is that wheel hub is made two, and two joint stays the mounting groove position, and increases interface.
For ease of changing, it is to adopt bolt to connect that the installation skirt of the heavy wall inner tube of a tyre of the present utility model is gone in the wheel rim mounting groove of wheel hub.
The utility model is compared with the run flat tire, has safety and reliability, even can guarantee that tire when air pressure is zero, still can not come off from wheel rim, has prevented to greatest extent to blow out, and guarantees traffic safety; And mass of system is little, and productive costs is low.
The utility model will be further described below in conjunction with accompanying drawing:
Accompanying drawing is a main cutaway view of the present utility model.
Embodiment: referring to accompanying drawing, the utility model is mainly assembled by aluminium alloy wheel hub 8 and tire 2, has particularly set up a small-sized heavy wall rubber inner tube 1 in the utility model, and sicula cross section external diameter is 80mm, and wall thickness is 20mm.Design has the skirt 5 of installation on the interior circle of the inner tube of a tyre 1; Wheel rim on the wheel hub 8 of the present utility model is formed by left and right two halves 3 and 7 butt joints, the joint of two halves leaves mounting groove position 6, the installation skirt 5 of the above-mentioned small-sized heavy wall inner tube of a tyre 1 is inserted in the mounting groove position 6 of wheel rim joint, uses bolt 4 one that is fixedly connected promptly to constitute a safe and reliable burst-proof tyre.
Wheel rim of the present utility model also can be made integral type (being regardless of two halves), mounting groove can be made into several discontinuous groove positions on it, then correspondingly on the interior circle of the heavy wall inner tube of a tyre be shaped on some skirts are installed, skirt is installed is inserted mounting groove and can adopt seccotine to be fixedly connected.
Principle of work of the present utility model is: when air pressure just often, travel the same with normal wheels; When air pressure reduces, because of the anti-gas-leak effect of tire 2 self, and under the effect of the small-sized heavy wall inner tube of a tyre 1, can the same cruising with the run flat tire; When taking place to collide, serious collision such as strikes obstacles, when tyre break even wheel rim broke, air pressure reduced to zero rapidly; The heavy wall inner tube of a tyre 1 is had an effect at this moment, is crushed out of shape, and just withstands the tire toe, prevents that tire from slipping at the bottom of the rim gutter, and bears vehicle weight together with cover tire, and automobile still can be travelled with certain speed, guarantees traffic safety.
Claims (3)
1. be used for the burst-proof tyre on the power actuated vehicle, have wheel hub tire is arranged, it is characterized in that: on the wheel rim of wheel hub, be shaped on the mounting groove structure, set up a small-sized heavy wall inner tube of a tyre, circle is gone up design in its tire the installation skirt, the installation skirt of the heavy wall inner tube of a tyre is gone in the wheel rim mounting groove of wheel hub and is fixed.
2. burst-proof tyre according to claim 1 is characterized in that: the mounting groove structure on the wheel rim of wheel hub is that wheel hub is made two, and two joint stays the mounting groove position and increases interface.
