This self-inflation tyre that the present invention proposes is the revolution improvement to existing tire, because a plurality of (multistage) pump air bag (5) is arranged to be placed wherein, tire is whenever advanced a week each breathing of these pump air bags once on the ground, so aeration speed is quite fast, can satisfy fitness for purpose.And, simpler, easy to manufacture, cheap than existing various self-inflation tyre scenario-frames.
Describe a preferred embodiment of the present invention below in conjunction with accompanying drawing, each accompanying drawing is:
Fig. 1, the present embodiment self-inflation tyre pass through the viewgraph of cross-section that get at its pump air bag middle part;
Fig. 2, the cutaway view of getting along the II-II line among Fig. 1.
The parts title of each symbolic representation among the figure is:
(1) fuse pipe, (2) ligament, (3) add heavy case, (4) capillary high pressure hose, (5) pump air bag,
(6) one-way cock, (7) main valve, (8) inner tube of a tyre tube, (9) press logical dust cap, (10) tire tube valve.
Dotted arrow fingering entraining air stream among Fig. 1, solid arrow refers to pump air bags air-flow.Fuse tube (1) is also used the canvas filler rubber manufacturing with rubber or canvas filler rubber manufacturing, ligament (2), and hardened layer (3) is one deck tire tube material of thickening.
Certainly the inflation principle of this tire can 1 be described below in conjunction with the accompanying drawings:
Open and press logical dust cap (9), fuse tube (1) is connected atmosphere, the tire that gives earlier existing certain tire pressure is in ground surface, when the tire of locating when a pump air bag (5) is flattened by ground, this place's ligament (2) is loose, because of the air pressure in the inner tube of a tyre chamber greater than the air pressure in the fuse tube (1), so the one section fuse tube in this place (1) is crushed, force pump air bag (5) compression air wherein in this section, when the air pressure after the supercharging surpasses in the inner tube of a tyre chamber air pressure, promptly flow into capillary high pressure hose (4) and also flow into the tire chamber then by the terminal one-way cock (6) of pump air bag (5).
When the tire of locating when this pump air bag (5) breaks away from ground, this section tire opens, this section ligament (2) is tightened up, owing to add the width (see figure 1) of the transversal surface width of heavy case (3) greater than fuse tube (1) inner chamber transversal surface, pretend the atmospheric pressure that is used on the fuse tube (1) less than acting on the atmospheric pressure that adds on the heavy case (3), this section fuse tube (1) is drawn back again, this pump air bag (5) in it open by self elastic force and from fuse tube (1) by an one-way cock of front end (6) suck air.Toward and renew, tire whenever circles, each pump air bag (5) is all finished circulation of air-breathing and exhaust separately successively.
All there is a moment in each pump air bag (5) in the process by compression, air pressure in the pump air bag (5) is from being elevated to approaching tire pressure value this moment near a barometric pressure this moment, produce the equilibrium appearance of middle air pressure of pump air bag (5) and tire chamber internal gas pressure, even be lower than the tire pressure value, if pump air bag (5) can not further compress, just can not be to the gas transmission of tire chamber.Aforementioned fuse tube (1) transversal surface width is greater than the width (see figure 1) of pump air bag (5) transversal surface in it, so the tire internal gas pressure is applied to the total power (ligament this moment (2) is loose) on the fuse tube (1), thereby be applied to the power on the pump air bag (5), can outwards be applied to self elastic force sum of total power on pump air bag (5) inwall and pump air bag (5) and fuse tube (1) greater than the interior gas of pump air bag (5), so just guaranteed the further compression of pump air bag (5), air pressure reaches the purpose to the gas transmission of inner tube of a tyre chamber above air pressure in the tire chamber in pump air bag (5).
Multistage pump gas is to adopt in the tire that the specified atmospheric pressure value of tire is had relatively high expectations.Only need two or many pump air bags (5) head and the tail are ganged up mutually, then the last grade pump air bag (5) just can be discharged more high-voltage gas.Can prove, the anticyclonic pressure value that two stage pump gas is discharged be single-stage compression ratio square doubly, the anticyclonic pressure value that triple stage pump gas is discharged be single-stage compression ratio cube doubly.
One-way cock (6) can unidirectional unlatching under far below an atmospheric draught head, thereby the charge efficiency that guarantees pump air bag (5) has high value.And good reliability, volume is minimum.
When inflation of tire arrives certain atmospheric pressure value, tire under the certain load lands to be out of shape and will be equal to or less than certain value, and pump air bag this moment (5) can not be closed effectively, and its compression ratio is less than certain value, from tire was still being advanced, pump air bag (5) also quits work.Lower wall spacing on the cavity of setting pump air bag (5) is with the atmospheric pressure value that determines that tire can be charged to.Its automatically regulating function that Here it is.
In the time of need not inflating, can close the main valve (7) in the tire tube valve (10), only need to rotate and press logical dust cap (9) to realize.
Be charged to the tire that requires atmospheric pressure value, after closing main valve (7), be not open to atmosphere, because inevitably there is slow seepage at fuse tube (1), pump air bag (5) and one-way cock places such as (6), after after a while, might cause in the inner tube of a tyre chamber air leaks among fuse tube (1), to such an extent as to reach the degree that fuse tube (1) inner and outer air pressure equates.This will help reducing the subsidiary load that bears on core tube (1), inner tube of a tyre tube (8), the ligament (2), even subsidiary load disappears, and will be favourable to increasing the inner tube of a tyre life-span.
Self-inflation tyre is that the roller tire lands that to cause the work done of tire internal gas pressure difference to realize gas filed automatically in distortion.One of self-aerated prerequisite is that air pressure will surpass an interior barometric pressure of fuse tube (1) in the tire chamber.Also can inflate automatically under the gas filed situation outside nothing is given earlier in order to make tire, for the less tire (as cycle tyre) in tire chamber footpath can adopt thicker, can bearing certain pressure and unbending ligament (2) is made, under free position, can inflate automatically guaranteeing.And ligament that is thin, that can only bear pulling force be do less than.
