Description
Technical field
The utility model is related to tyre technologies, and in particular to a kind of to exempt from suitable for vehicles such as electric vehicle, bicycles
Pneumatic tire.
Background technology
Non-inflatable tyre have the advantages that wear-resisting, bearing capacity it is strong, without blow out, without gas leakage, solve pneumatic tire before use
Check tire pressure and often inflate, even and in easily by punctured blow out cause safety accident defect.The prior art is public
The non-inflatable tyre of diversified forms, such as solid tyre are opened, ontology is interior, and there are one the tunnel cavities that wheel hub is parallel to several
The air core tyre of body.But solid tyre heavier-weight, cost is high, and hardness is big.
Utility model content
The utility model overcomes the deficiencies in the prior art, and it is good, at low cost and can anti-knocking over to provide a kind of comfort
Non-inflatable tyre.
In order to solve the above technical problems, the utility model uses following technical scheme：
A kind of non-inflatable tyre, it includes tire body, and the tire body top side is crown, the tire body inside
For placenta, the tire body both sides centre is tyre sidewall；There is inner cavity in the tire body；The tyre sidewall is distributed with axial heavy
Hole；The placenta surface is fluted；The tire assembles required hub outside diameter and is more than tire diameter；The wheel hub is for blocking
The deck of tire placenta circumferentially has boss corresponding with the groove.
Further technical solution is to be provided at least two inner cavities in the tire body.
Further technical solution is that the counterbore depth is no more than the 1/3 of overall tire width.
Further technical solution is that the two neighboring counterbore use is interspersed up and down.
It is bucking ladder or terrace with edge or taper platform structure, the counterbore width that further technical solution, which is the counterbore,
From gradually increasing to tyre sidewall direction close to centerline.
It is arc transition that further technical solution, which is the counterbore adjacent surface,.
Further technical solution is that the tire body both sides counterbore is arranged using asymmetric.
Further technical solution is the trapezoidal structure of the groove, and the recess width is from placenta position to tire
Internal gradually to increase, the groove is evenly distributed on placenta surface.
Compared with prior art, one of the advantageous effect of the utility model embodiment is：The utility model exempts from inflated wheel
There are multiple inner cavities to promote tire flexibility in tire ontology, the setting of counterbore makes the rigidity in tyre bead portion is appropriate to decline, improves tire
Damping property comfort.The usage amount of rubber is reduced in inner cavity and tyre sidewall setting counterbore in tire body, reduces tire cost.Tire
Placenta surface increases several trapezoidal grooves, and wheel hub deck increases several corresponding boss, increases the contact surface of tire and wheel hub
Product, increasing friction force.Groove is mutually twisted with boss, and powerful snap-in force is generated during tire used.To prevent the wheel position of foetus
It moves and skids, while avoiding tire that knocking over occurs, improve safety.

Specific implementation mode
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only
It is an example in a series of equivalent or similar characteristics.
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawings and embodiments.
In the following detailed description, many specific descriptions are described for illustrative purposes so as to thoroughly understand institute
Disclosed embodiment, it is clear, however, that one or more embodiments can be in the case where specifically describing without using these
Implement, in other instances, known structure and device is schematically shown, to simplify attached drawing.
As shown in Figures 1 to 5, one embodiment according to the present utility model, the present embodiment disclose a kind of non-inflatable tyre,
The non-inflatable tyre includes tire body 1, and the tire body top side is crown, is placenta on the inside of the tire body, described
It is tyre sidewall among tire body both sides.Specifically, there are several inner cavities 4 in tire body 1 described in the present embodiment, tire is suitably reduced
Body intensity promotes elasticity and damping effect.
Further, non-inflatable tyre ontology described in the present embodiment 1, in its two side, upper edge tire axial is uniformly distributed
There are several counterbores 2.Inner cavity 4 is arranged in tire both sides and counterbore 2 reduces the usage amount of rubber, mitigates non-inflatable tyre weight, reduces
Tire material cost.
Wherein, counterbore outside height b ＞ counterbore inside heights c, the counterbore 2 are bucking ladder or terrace with edge or taper platform knot
Structure.It is under pressure during tire running, partly deforms upon dispersion pressure between adjacent two counterbore, can inhibit to cross step
When impact and phenomenon of jolting later.
Further, on the basis of the above embodiments, two neighboring counterbore is used and is interspersed up and down by the present embodiment
The reaction speed deformed caused by its external force is helped speed up, the damping property and comfort of tire are promoted.To ensure tire flexibility,
Counterbore size is unsuitable too small, and quantity is unsuitable very few.Spacing 5mm~10mm between described two adjacent counterbores 2.The counterbore 2
Depth d≤overall tire width a/3, and in the anisopleual distribution of tire, ensure tire intensity, make tire force evenly.
Further, according to another embodiment, the tyre sidewall of the counterbore 2 and the tire is set to 21 mistake of circular arc
It crosses, when 2 stress of counterbore deforms, circular arc 21 can reduce stress concentration, avoid edge from breach occur, and then extension tire makes
Use the service life.
Placenta recess width e2 ＜ wheel hubs boss the second width f2 ＜ placenta grooves of tire body 1 described in the present embodiment
1 ＜ wheel hubs the first width of boss f1 of width e.With after wheel hub assembly, placenta groove 3 is mutually twisted tire with wheel hub boss 5, is prevented
Tire is subjected to displacement and skids in the process of moving.Tire is tightly stuck on wheel hub, and tire is made not deviate from from wheel hub, to
Prevent the generation of knocking over phenomenon.The elasticity that can avoid fully relying on tire body 1 in this way wales wheel hub.
Further, 31≤hub outside diameter of tire body internal diameter 51 in the present embodiment；Placenta 32≤wheel hub of groove diameter is convex
Platform diameter 52.Tire does not have excessive tensile, reduces tire used and generates elastically-deformable probability afterwards for a period of time.
" one embodiment " for being spoken of in the present specification, " another embodiment ", " embodiment " etc., refer to combining
