Abstract

The utility model discloses an automobile tyre, including rim, matrix and lag, the lag is by outward to interior skid resistant course, puncture -proof layer, buffer layer and the buffer layer of including in proper order, the interval sets up many hexagon convexity layers and many trapezoid depression layers on the skid resistant course, puncture -proof layer is cellular rubber layer, the buffer layer internal surface with latch and draw -in groove that the buffer layer surface passes through the cockscomb structure match the bonding, set up many heliciform steel wire strengthen muscle in the buffer layer. The utility model discloses can increase the intensity of tire, when the tire internal gas pressure is not enough, have supporting role to car body's partial weight to reducing car body and being used in the gravity on the tire, prevent to a certain extent that the tire is bad because of the not enough quilt book of atmospheric pressure, but also can prevent that the tire from being punctured, the practicality is strong.

Description

A kind of doughnut

Technical field

The utility model belongs to automotive field, especially relates to a kind of doughnut.

Background technology

Tire is the annular elastic rubber product rolled at various vehicle or the ground connection mechanically assembled, is usually arranged in alloy rim, can support vehicle body, buffering foreign impacts, it is achieved with the contact on road surface and ensure the operating performance of vehicle. When use for a long time or be subject to mechanical wear comparatively serious time, it is easy to make tire glue-line impaired, and cause can not continuing to use, it is necessary to changing tire, cost is higher, thus, is contained on automobile cover, and the tire protecting jacket for the protection of tire is more and more welcome. But current protective jacket of automobile tire, mostly only there is the function that protecting tyre glue-line is impaired, in tire, air pressure is not enough, vehicle body gravity is often all applied on tire, thus make the tyre surface of tire and boundary, sidewall place extrude pleat road and make that tire is impaired even to be damaged, this weak point existing for prior art.

Notification number CN203543537U discloses a kind of doughnut, comprise the protecting jacket body mated mutually with outer surface of tire, described protecting jacket body comprises cover face and is fixed on the cover side of both sides, cover face, the outside surface of described cover side is provided with stiffening web and the connection bump with connection hole, it is provided with web member in described connection hole, on each cover side, described stiffening web comprises two annular projections being parallel to each other, this novel outside surface overlapping side is provided with stiffening web, the intensity of cover side can be increased, when in tire, air pressure is not enough, the part weight of body of a motor car had supporting role, thus reduce the gravity that body of a motor car acts on tire, prevent to a certain extent tire because of air pressure not enough bad by pleat, but this kind of tire focuses on carcass surface and gains in strength, performance and the intensity of whole tire is not thoroughly changed from internal layer, bigger weight cannot be born, the intensity of guarantee tire that also can not be long-time and performance.

Practical novel content

In view of this, the purpose of this utility model is for the deficiencies in the prior art, provide the technical scheme of a kind of doughnut, the program can increase the intensity of tire, when air pressure is not enough in tire, the part weight of body of a motor car is had supporting role, thus reduce the gravity that body of a motor car acts on tire, prevent tire from being rolled over because air pressure is not enough to a certain extent bad, but also it is possible to prevent tire and is punctured, practical.

For achieving the above object, the utility model by the following technical solutions:

A kind of doughnut, comprise wheel rim, carcass and protecting jacket, described protecting jacket comprises non-skid finish, antipricking layer, buffer layer and buffer layer from outside to inside successively, on described non-skid finish, interval arranges the protruding layer of many hexagons and many trapezoidal recess layers, described antipricking layer is cellular rubber layer, described buffer layer internal surface and described buffer layer outside surface, by the latch of spination and the coupling bonding of card groove, arrange many spirrillum steel wire stiffening webs in described buffer layer.

Preferably, it is provided with wearing layer between any two protruding layers of adjacent described hexagon and trapezoidal recess layer.

Preferably, the height of the protruding layer of described hexagon is 3 ~ 8mm, and the degree of depth of described trapezoidal recess layer is 2 ~ 5mm.

Preferably, described many spirrillum steel wire stiffening webs are arranged in described buffer layer to one week around carcass shafts.

Preferably, it is coated with preservative coat outside described non-skid finish.

The beneficial effects of the utility model are:

1. on the utility model non-skid finish, interval arranges the protruding layer of many hexagons and many trapezoidal recess layers, hexagonal protruding layer adds anti-skidding area, the design that convex-concave combines makes tire can adapt to various different road surface, non-skid property is better, raise into play and support preferably and provide protection, thus improve the security of vehicle movement, it is provided with wearing layer between any two protruding layers of adjacent described hexagon and trapezoidal recess layer, the wear resisting property of protecting jacket can be increased, so that protecting jacket is while playing protective effect, the work-ing life of self can also be increased,

2. the utility model arranges cellular rubber antipricking layer, tire not only not easily punctures, effectively reduce rate of blowing out, and also have elastic force, the needs of automobile tire elasticity distortion in motion can be met, cellular antipricking layer is made more to have cushioning pocket, it is possible to also for the heat radiation of doughnut provides space while effectively avoiding pricking object protection carcass;

3. the utility model can make buffer layer and buffer layer more combine closely by buffer layer and the buffer layer of the latch of spination and the coupling bonding of card groove, effectively prevents the slip of protecting jacket;

4. many spirrillum steel wire stiffening webs are set in the utility model buffer layer, the intensity of whole protecting jacket can be increased, thus when tire QI-insufficiency, the part weight of vehicle body is played a supporting role, thus reduce the gravity of vehicle body on tire, the structure of spirrillum makes stiffening web have certain elasticity, increase while the even whole protecting jacket intensity of buffer layer can also compensator or trimmer pressure, to play damping and the effect of dispersion vehicle body pressure.
