Abstract
The utility model belongs to an inflation free type tyre, wherein, an outer ring face of an annular tyre body is provided with a plurality of grooves which are arranged in the radial direction and divide the tyre body into a plurality of tyre bodies; internal hollow cavities which are arranged along the circumferential direction are arranged in each tyre body; an integral tyre crown layer is also arranged out of the tyre body and connected with the tyre body; an outer hollow cavity is arranged on the tyre crown layer. The utility model has the advantages of good elasticity, broad application for bearing, optimize performance for sitting and carrying, good safety, braking performance and adaptability for sitting, long service life and oil saving.
Description
The utility model relates to a kind of non-inflatable tyre, particularly exempts from gas filed cavity type tyre.
Existing non-inflatable tyre real core arranged with band two kinds of cavity.Notification number be CN2107395U's " sponge filled type solid tyre " owing to be whole real cored structure, thereby its shock resistance and elasticity are all relatively poor; The non-inflatable tyre of disclosed band cavity, have that I patent, the patent No. is 99257102.2 " non-inflating cavity formula tire ", there is a circle steel band at the interior ring place of the ring shaped tyre of this tire, a plurality of grooves that radially are provided with are arranged on the outer ring surface, the full annular carcass is separated into continuous multistage carcass, the mutual edge cavity that circumferentially axis is radially arranged with vertically arranging is arranged in every section carcass.This tire is owing to be the design of individual layer cavity, thereby the applicable area of its carrying is narrower, have the sensation of spring during light(-duty) service, can occur soft flat phenomenon during heavy service again, use the driver comfort of vehicle when empty wagons or heavily loaded travelling of this tire not good enough.
The purpose of this utility model be to provide that a kind of elasticity is better, the applicable area broad of carrying, take with cargo-carrying ability all suitable exempt to inflate the double-layer cavity tire.
For achieving the above object, the utility model has adopted following technical scheme: outside the carcass of " the non-inflating cavity formula tire " of my original invention the annular whole crown layer that is attached thereto is set, outer cavity is arranged in the crown layer.Be that a plurality of grooves that radially are provided with are arranged on the ring shaped tyre of the present utility model, whole carcass is separated into the multistage carcass, the internal layer cavity is all arranged in every section carcass, the annular whole crown layer that carcass is attached thereto outward in addition has outer cavity in the crown layer.
Outer cavity in the crown layer is preferably sphere, cylindricality, taper or taper type areola.
Outer cavity is preferably by honeycomb arrangement.Internal layer cavity in every section carcass can radially be arranged to two-layer at least, promptly can be one deck, also can be two-layer, three layers or multilayer.Internal layer cavity in the crown also can be one deck, two layers or multilayer.The groove that whole carcass is separated into the multistage carcass vertically runs through the sidewall, both sides along carcass.
Aspect manufacturing process, the post-cure technology that can adopt carcass and crown to vulcanize respectively; Aspect material, the colloid compound design of crown layer can be become more high resilience and abrasion resistant rubber bodies, the colloid compound design of body piles is become the rubber bodies of high resiliency, high hardness, match in order to planform with carcass and crown.Like this, lean on the weight of the resilient mounting vehicle of crown layer when sub-load, just do not have very hard sensation in travelling, because carcass has enough intensity, the degree of deflecting on sidewall is little, so move brisk when heavy duty or overload.
Owing to taked technique scheme, thereby the utility model compares with existing non-inflatable tyre with common air-inflation tyre, has following advantage:
1, safety is good: because the tire internal cavity does not have high pressure, can not leak gas, also not have obstruction even bundle is worn a plurality of cavitys, rubber itself is flexible, can seal voluntarily, long-time continuous is travelled and also can not blown out on express highway, can effectively prevent the traffic accident that vehicle causes because of blowing out.
2, reduce expenses and increase work efficiency: conventional tyre gas leakage will tire patching, and not only time-consuming but also expensive, the utility model does not then have this disadvantage, has not only saved expense but also improved work efficiency.
3, deceleration and stopping performance is good: the utility model can be made into the tire of less flat ratio, because flat ratio is little, wheel rim and brake disc just increase relatively, brake lighter laborsaving, more effective; Because of crown is thin, the quality softness to the ground strong adhesion, especially on the oil circuit of rainy day humidity, is difficult for producing " hydroplaning " simultaneously, and deceleration and stopping performance is very superior.
4, take with cargo-carrying ability all suitable: it is radially all less with circumferential rigidity, no very hard sensation, especially in running at high speed, its lateral deviation resistance is big, travels to be difficult for producing on mire or oil circuit and is partial to, and has good ride comfort and stationarity.
5, long service life: because flat ratio is less, the area that contacts to earth is relatively large, crown pressure over the ground is less relatively, so abrasion intensity reduces, because its sidewall degree of deflecting in service is little, and cal val is low, carcass is difficult for aging again, life-span, than the long 1-1.5 of air tyre doubly operating cost reduced more than 50%.
6, energy-conservation fuel-economizing: common air tyre, crown is made of cushion layer, band bundle, cord, layer of cloth etc., and crown is thick and hard, and " standing wave " phenomenon is serious in travelling, and sliding resistance is big, and power consumption is high.The utility model does not have above-mentioned structure, and its crown is thin and soft, is difficult for producing " standing wave " phenomenon, even produce a little hoop-stress, is also admitted by the carcass groove and digests.Through measuring and calculating, its sliding resistance reduces 30%, and consumption of fuel can reduce 8-10%.
7, can improve safe driving speed: because of not blowing out, cal val is low, strong adhesion over the ground, thereby can improve safe driving speed 5-10%.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the front view of the utility model carcass.Fig. 2 is the birds-eye view of the utility model carcass.Fig. 3 is along the cutaway view of A-A line among Fig. 1.Fig. 4 is along the cutaway view of B-B line among Fig. 1.
In Fig. 1, Fig. 2, Fig. 3 and embodiment shown in Figure 4, there are 16 grooves 2 (as seen from Figure 4) that vertically connect along radially being provided with of carcass, along carcass the middle and upper part of ring shaped tyre 1 of the present utility model.Groove 2 is separated into 16 sections carcasses with whole carcass five equilibrium.5 row, the 5 row long column shape internal layer cavity 3 of totally 25 truncated cones is all arranged in every section carcass, and whole carcass just has the long column shape internal layer cavity 3 of 400 leak free truncated cones.Also be connected with annular single-piece crown layer 4 outside the carcass 1.One deck 12 circles, 144 on every circle, 1728 outer cavitys 5 of leak free short cylinder are altogether arranged in the crown layer.
Use vehicle of the present utility model under steam, when the carcass pressurized, the sections line that contacts to earth can circumferentially extend along carcass, its elongation is admitted by two adjacent grooves, thereby not having significantly " standing wave " phenomenon, sealed cavity plays the effect of little ball, makes more high resilience of tire.The utility model not only can be used as the tire of motor bike, and can be used as the tire of bicycle, automobile, particularly car and mid-get car.
