Specific embodiment
In Fig. 1, design has interior post holes with the level on the wheel rim 1 of wheel, and support tube 7 is fitted into.Outside support tube 7
Cylindrical surface step has sealing ring 2 on 1 upper limit of wheel rim, step.7 inner cylinder face of support tube has been arranged symmetrically guide groove a and bayonet
B, and have interior step (can refer to Fig. 4).To guarantee that support tube 7 is easy for installation, accurately, there are positioning in support tube 7 and 1 contact position of wheel rim
Pin 8.After support tube 7 is installed on wheel rim 1, indentation retainer ring 6 is positioned.It is straight that 6 height of retainer ring is less than the external port of step in support tube 7
Diameter not only makes port keep communicating with atmosphere, also to allow screwdriver that can be inserted into.11 head of support leg is cylinder, other end instep
There is the arc (can refer to Fig. 3) as 10 inner tread of rubber tyre.The head movement of support leg 11 is mounted in support tube 7, is used
The interior step of support tube 7 limits, and has sealing ring 3 on step.There is annular groove on 11 head cylindrical surface of support leg, and sealing ring 9 is mounted on ring
In slot, Double seal ring sealing is formed.When 11 head of support leg is pressed in support tube 7 on step, 11 instep of support leg and rubber wheel
10 inner tread of tire has distance H, deflection when normally rolling and impact for tire.Fixture block 4 has been arranged symmetrically in support leg 11,
4 one end of fixture block is stuck in the guide groove a of support tube 7, and one end has step to limit 4 stroke of fixture block, and 5 one end of leaf spring is fixed on support leg 11
On interior side column, one end is pressed on fixture block 4, provides sports force for fixture block 4.
When 10 normal high speed scroll of rubber tyre, the pressure to 11 head disc of support leg of the high pressure gas generation in tire
Power is greater than centrifugal force caused by support leg 11, and 11 head of support leg is pressed in support tube 7 on step, seals support tube 7
Port, wheel is as common wheel function at this time.
In Fig. 2, when automobile unexpected tyre explosion in running at high speed, intrauterine pressure pop-off, support leg 11 is lost
Pressure support ventilation in tire, the centrifugal force produced by high-speed rotating wheel throw away from step out of support tube 7, are mounted on support leg
Guide groove a of the fixture block 4 on support tube 7 on 11 is also thrown away therewith, and when fixture block 4 is thrown to the bayonet position b, fixture block 4 is limited,
Fixture block 4 is pressed into bayonet b, lock support foot 11, at this moment all support legs 11 being thrown out of, in tire under the action of leaf spring 5 simultaneously
Interior one Clearance joints of composition support tire, are not biased towards running car.
What needs to be explained here is that can fixture block 4 throw away indentation bayonet b, lock support foot 11 in tyre explosion moment.
First, when tyre explosion is instantaneous, seam broken be it is outside, tire is intracavitary not to have residue, does not influence support leg 11 and throws away；Second, only
The tire chamber contacted with road surface is crushed, that is, has one piece of support leg 11 to be crushed on road surface, but wheel is rolling, the support leg 11 pressed
After rolling across road surface rapidly, and it is thrown out of locking, has thrown away and the support leg 11 locked is forced into road surface, to reach support automobile
Balance；Third, leaf spring 5 will have certain pressure；4th, worry that the support leg 11 thrown away pins fixture block 4, makes fixture block 4 in bayonet b
Place not can enter bayonet b.The Impact direction at bayonet b of fixture block 4 is variation, i.e., fixture block 4 when support leg 11 is acted on by centrifugal force
It is an Impact direction, when support leg 11 presses upper road surface to be acted on by vehicle weight, the Impact direction of fixture block 4 is exactly the opposite, card
Block 4 does not stress in Impact direction change moment, and leaf spring 5 gives 4 one Impact directions of fixture block always, therefore fixture block 4 is can to block
In card inlet b.
The installation of support leg 11: being packed into wheel rim 1 with usual way on one side for rubber tyre 10 first, then will support
Foot 11 never loads onto the tyre beads insertion tire chamber of wheel rim 1, and head is allowed to stretch out from the port of wheel rim 1, insertion band installation inclined-plane support
Pipe 7, rotating support leg 11 or support tube 7 makes its fixture block 4 be caught in guide groove a, and is pushed into 7 bottom of support tube at step, then
The support tube 7 assembled is inserted into wheel rim 1 along positioning pin 8, and after all installing, then by the another side loading wheel rim 1 of tire, indentation blocks
Enclose 6 lock support pipes 7, inflation.
Here it should be noted that, this design (referring to Fig. 3) of support leg, primarily to do not influence support leg 11 by
In the case where power, mitigate the weight of support leg 11, reduces centrifugal force.Such as:
If 10 centimetres of 11 head body diameter of support leg, 9.5 centimetres of the external port of step, i.e. radius 4.75 in support tube 7
Centimetre, 2.2 kilograms every square centimeter of intrauterine pressure, then 11 head disc gas pressure of support leg: 4.75 × 4.75 × 3.14 ×
2.2=155.8 kilogram.
Centrifugal force multiplies radius equal to 11 mass of support leg and multiplies angular speed of wheel square.Setting speed reaches 170 public affairs per hour
In when support leg 11 be possible to be thrown out of, that is centrifugal force is equal with 11 head disc gas pressure of support leg at this time, also reaches
To 155.8 kilograms.
170 kilometers i.e. 47.2 meters per second per hour, wheel diameter takes 0.6 meter, and wheel excircle perimeter is 0.6 × 3.14=
1.884 meters, the wheel 47.2/1.884=25 per second that turns turns, and the angular speed of wheel is 2 × 3.14 × 25=157 radian per second, branch
Mass centre's radius of support foot 11 is calculated by 0.25 meter, then the quality of support leg 11 are as follows: 155.8 × 9.8/0.25 × 157 × 157
=0.2477 kilogram.That is, it is ensured that vehicle up to per hour 170 kilometers when, support leg 11 is not thrown out of, the matter of support leg 11
Amount is necessarily less than 0.2477 kilogram.
The high speed requirement small to support leg quality is met, then blowing out when to automobile low speed, can support leg be got rid of
Out? as long as centrifugal force caused by support leg, greater than sealing ring 9 to the resistance hysteresis of support tube and fixture block to the frictional force of support tube
The sum of, support leg can be thrown away.Such as:
When 30 kilometers per hour of speed, support leg quality takes 0.24 kilogram, then centrifugal force caused by support leg is
4.728 kilograms (calculation method is same as above).
Since the 11 head disc of critical speed (per hour 170 kilometers) support leg of the closer setting of speed is to sealing ring 3
Pressure it is smaller, in order to guarantee vehicle in the leakproofness of ultrahigh speed tire chamber when driving, so increasing on support leg head cylindrical surface
One of sealing ring 9.
There are also a kind of functions by the present invention: rubber tyre 10 is normal when vehicle parking, night or after a few days is parked, to drive
When, discovery rubber tyre 10 is flat (not having gas), as long as at this moment the support leg 11 for not contacting ground is shifted into hand (or screwdriver)
Then position starts automobile forward movement and concedes the support leg 11 pressed, then the support leg 11 pressed just now is shifted onto position, vehicle is delayed
Slowly the repairing of tyre repair shop is reached.
The method of tire dismantling and the sequence of installation on the contrary, it is noted here that, the fixture block for being caught in bayonet can use flat mouth spiral shell
Silk knife pushes.
The present invention is not suitable for tubed tyre.
Above-mentioned is that this hair can be understood and applied for convenience of those skilled in the art to the description of embodiment
It is bright.Those skilled in the art obviously can easily modifications to the embodiments described above may be made, and described herein general
Principle is applied in other embodiments without having to go through creative labor.Therefore, the present invention is not limited to the above embodiments, ability
