Embodiment 1
A kind of high durable non-inflatable tyre of the present embodiment, as shown in Figure 1, Figure 2, Figure 3 and Figure 4, including
Carcass 1；
Hollow hole 2 is the through-hole for being opened in 1 side of carcass；
Further include connection chamber 20, is the toroidal cavity being opened in carcass 1, hollow hole 2 is interconnected；
The hole of the hollow hole 2 is gradually reduced in the middle part of hollow hole 2 both ends of the surface to hollow hole 2 without leave.
Hollow hole 2 is circumferential through the side that carcass 1 is arranged in, and to guarantee balance when tyre rotation, hollow hole 2 is uniform
Setting in 1 side of carcass, the shape of hollow hole 2 includes but are not limited to circle, ellipse, square, diamond shape, polygon etc.
The through-hole of shape, in view of circular through hole formed 2 stress of hollow hole when be evenly distributed, compared to other shapes through-hole, circle is engraved
The time of fatigue damage, damping effect was more preferable at most when emptying aperture 2 resists tire used, therefore the present embodiment is made using circular through-hole
For hollow hole 2.
In actual use, the impact force that carcass 1 is subject to is transmitted to hollow hole 2 by tyre surface, and engraved structure passes through at this time
Deformation-recovery-deformation carries out consumption buffering to impact force, is finally reached damping purpose, and each hollow hole 2 is respectively a list
Member has no direct correlation between each other, therefore when by impact force, it is that the several hollow holes 2 nearest apart from impulse source carry out damping
Effect, the characteristic of solid carcass so that hollow hole 2 be difficult it is multiple carry out collaboration damping, in view of this, the present embodiment is in carcass 1
Equipped with connection chamber 20, the hollow hole 2 on carcass 1 is together in series, the toroidal cavity structure in carcass 1 can inherently impact
Power, which transmits, to be made circumferentially to carry out dispersion transmitting to power, therefore, when tire is impacted, under the action of being connected to chamber 20, band
It moves more hollow holes 2 to consume the energy of impact force, the impact force energy being eventually transferred on vehicle body is less, makes tire
Damping effect greatly improve, and by dispersion of the connection chamber 20 to impact force, so that the impact force that single hollow hole 2 is born becomes
Small, 2 deformation of hollow hole-recovery amplitude, frequency become smaller, so that the aging speed of hollow hole is slack-off, to improve hollow hole 2
The durability degree at place, and then improve the durability degree of tire.
Traditional hollow hole 2 is straight tube, when some impurity particle objects etc. are entered in hole, is generated when being rotated by tire
Centrifugal force, the hollow hole 2 of straight tube for traveling balance consideration is generally parallel to level road, if therefore impurity thing not by
Other active forces can be tightly attached to 2 hole wall of hollow hole under the influence of centrifugal force, be not easily disconnected from, impurity thing is accumulated in over time
Hollow hole 2 is blocked in hollow hole 2, in winter when hollow hole 2 in easily to occur to freeze be also the principle of similitude, hollow hole 2 is blocked meeting
It causes following risk: 1) increasing the quality of carcass 1, make resistance increasing when driving, increase traveling power consumption；2) hollow hole after blocking
2 lose the effect of stress damping；3) it blocks and is likely to have sharp object (such as stone) constantly contact in the impurity thing of hollow hole 2
And the carcass 1 of 2 hole wall of hollow hole is worn, the damage of carcass 1 is accelerated, Life of Tyre is seriously affected.
The present embodiment changes the straight-tube shape hole wall of hollow hole 2, make its hole without leave 2 both ends of the surface of hollow hole to the middle part of hollow hole 2
It is gradually reduced, just as horizontal hourglass from the point of view of the cross-sectional view of 1 radial section of carcass, as shown in figure 3, using the hole of this shape
Wall under the action of tire centrifugal force, is adjacent to hole wall when impurity thing enters hollow hole 2, but hole wall and non-horizontal in ground
Face, therefore impurity thing is not easy to obtain the support force of balance on hole wall and engraves so being easily detached from from hollow hole 2 to solve
The susceptible to plugging problem in vacancy.
The cross sectional shape for being connected to chamber 20 can be circle, ellipse, square, polygon etc., it is contemplated that circular cross-section
Connection chamber 20 is more preferable to the dispersion effect of power, and the point that few stress are concentrated, and the present embodiment selects the company of circular section shape
Cavity 20.
To guarantee to open up the balance of connection 20 rear tyre of chamber when in use, the connection chamber 20 of the present embodiment is set to hollow hole
2 medium positions, i.e. connection chamber 20 connect each hollow hole 2 from 2 aperture minimum of hollow hole.
Embodiment 2
A kind of high durable non-inflatable tyre of the present embodiment, is further improved on the basis of embodiment 1, such as Fig. 5, figure
Further include blister cavities 21 shown in 6 and Fig. 7, is opened in 2 middle part of hollow hole, is interconnected between blister cavities 21 via connection chamber 20.
A big reason of tire generation aging is caused to make the use temperature of tire, carcass is rubber product, to temperature
The tolerance of degree be it is very limited, in tire running, especially run at high speed, or in hot weather when driving, carcass
Can generate heat in ground friction, the continuous deformation of tire can generate heat, the heat on 1 surface of carcass relatively easily disperses, but tire
The heat generated in body 1, the heat generated in the middle part of hollow hole 2 are connected to the heat generated in chamber 20, since its neighbouring space is narrow
It is small, it is not easy to disperse, accumulation of heat causes temperature to increase, and over time, accelerates the aging of the position carcass 1.The present embodiment exists
21 structure of blister cavities is added in carcass 1, blister cavities 21 is located at 2 middle part of hollow hole, increases the space at 2 middle part of hollow hole, and by being connected to
