Description
Technical field
The utility model is related to a kind of tire, particularly a kind of air-free tyre；The utility model further relates to a kind of using preceding
State the automobile of air-free tyre.
Background technology
Tire is mounted on automobile and the component for rolling is contacted with ground.Tire be able to will not only bear right as transferring
The vehicle load of elephant, will also buffer the traveling impact that ground injustice causes.
Tire and wheel make motor racing in vehicle bridge (axle) power transmission and ground between.Therefore, tire and wheel arrangement should
Meet following basic demands：Enough load-bearing capacities and speed ability are good with less rolling resistance and running noise
Attachment characteristic and mass balance, wear-resistant, resistance to puncture, ageing-resistant and good air-tightness, quality is small, price is low, convenient disassembly,
Interchangeability is good.
Tire has various sorting techniques, wherein, it is divided into radial, cross-ply etc. by carcass structure difference；By curtain
Wire material difference steel splitting wire tire, half steel wire tire, staple fibre tire and cotton cord tyre；By different points of passenger cars of purposes
(referring to car, light bus) tire, commercial car (referring to lorry, motorbus) tire, off-highway use wheel tire, special purpose vehicle tire；
Press different points of highway tread pattern tires of tread contour, cross-country tread pattern tire, dual purpose tread pattern tire and extraordinary rib tire；Press section shape
Shape difference is divided to two kinds of conventional section tyre and low-profile tyre；It is divided to tubed tyre and tubeless tyre two by air tight manner difference
Kind.
Passenger vehicle tyre size is small, and high speed and comfortableness are good；Commercial car tire size is big, and bearing capacity is strong；It is off-highway
It is good with wheel tire tack, the resistance to puncture of tyre surface, it is adaptable to work under severe conditions.Highway tread pattern tire drag is small, make an uproar
Sound is small, it is adaptable to used on paved road, and wherein annular ribs tire is applied to good road surface, and transverse pattern tire is applied to soil
Stone road surface；Cross-country tread pattern tire is applied to bad road surface or is used without road area；Dual purpose tread pattern tire is suitable for use with pavement conditions
Protean occasion.
The widely used aerated rubber tyre of present automobile, pneumatic tire is to inject in confined space compressed air to keep
The tire of shock-absorbing capacity is obtained while tire shape by air pressure, wherein it is divided into tubed tyre and tubeless tyre again,
Tubeless tyre is called vacuum tyre.However, pneumatic tire is present is punctured or is difficult to when tearing the defect for keeping its shape.At a high speed
If pneumatic tire explosion during traveling, the operability of vehicle becomes extreme difference, be the reason for causing the major accidents such as overturning it
One.
In the key property of tire, tire it is elastic extremely important.When structure mechanics analysis are carried out to tire, such as scheme
Shown in 1, tire this elastic model is often divided into tread rubber layer 100, belt 200 and 300 3, sidewall elastic ring, and handle
Wheel 400 regards rigidity as, and with reference to Fig. 1 and Fig. 2, these three elastic rings form the lateral stiffness K of tires, radial rigidity KrWith turn
Dynamic stiffness Kt, lateral stiffness KsThe lateral deviation power of tire is determined, and lateral deviation power directly affects the control stability of vehicle, lateral deviation power becomes
Change easily causes shimmy of front wheels greatly；Radial rigidity KrDirectly affect the bearing capacity and ride comfort of vehicle；Rotational stiffness KtTo vehicle
Braking ability and startability influence are very big.
Present air-free tyre is progressively developed, and future also will progressively use air-free tyre.Air-free tyre be it is a kind of not
The tire of support force is realized by air, support and the buffering of tire are realized by material and structure.Air-free tyre is taken turns
Spoke outer ring substitutes belt, and sidewall is substituted with the spoke and spoke centre circle of spoke, and spoke inner ring is combined with wheel, air-free tyre
Tread rubber layer is essentially identical with pneumatic tire, therefore, the spoke of air-free tyre and the combination bodily form of tread rubber layer into bullet
Sexual function will substitute tread rubber layer, belt and three, the sidewall spring function of elastic ring of pneumatic tire, connection wheel and
The spoke of tread rubber layer, not only want tire keep cylindrical shape, but also can bear and buffer laterally, radially and rotation when
The effect of power and torque.
Air-free tyre due to the particularity of its structure, when there is hard objects to pierce through tire, can't as pneumatic tire that
Sample is blown out, and can be moved on, and greatly promotes power driving safety.But the foreign matters such as water, silt, stone are easily accessible without turbine
In gap between tire spoke, existing air-free tyre is poor to the discharge ability of foreign matter.
A kind of air-free tyre is disclosed in the Chinese invention patent specification of Application No. 201210458366.4, its structure
As shown in figure 3, including rubber tread 500, spoke 600, outer side band 700 and inner band 800.Due to the load from vehicle etc.,
Impact, the moment of torsion from wheel hub that frictional force, road pavement form from road surface are brought etc. form complicated internal stress, these power
Act on tire, so this air-free tyre has problems with：When by road shocks, buffer capacity is poor, causes
The ride comfort of vehicle traveling is poor；When vehicle is braked or is accelerated, the ability for resisting the moment of torsion of wheel hub is smaller, makes braking and acceleration
It is delayed.

Many, and interior spoke 25 corresponds arrangement with outer spoke 24, i.e., outer spoke 25 is identical with the quantity of interior spoke 24, and every outer
Spoke 24 corresponds to an interior spoke 25, and corresponding interior spoke 24 and outer spoke 25 are heavy with the intersection point b and b' of spoke centre circle 22
Close.Using the architectural feature, can be easier to produce radial deformation when tire from ground by being impacted, reduce wheel
The radial rigidity K of tirer, the ride comfort and comfortableness of the flexible and vehicle traveling of tire are improved, meanwhile, improve rotational stiffness Kt, carry
Vehicle high performance in braking or startup.
For the ease of by the foreign matter discharge in air-free tyre, it is preferable that as shown in fig. 7, left side spoke and right side spoke
Radial section after spoke outer ring merges is justified by the symmetrical straightway 212 in inner side straightway 211, both sides two and outside
Segmental arc 213 is constituted, and outer arc section 213 forms the appearance of spoke outer ring 21 after the axis axial-rotation of the air-free tyre
Face, inner side straightway 211 forms the inner surface of spoke outer ring 21, both sides straight line after the axis axial-rotation of the air-free tyre
Section 212 forms two sides of spoke outer ring 21 after the axis axial-rotation of the air-free tyre.Spoke centre circle 22 and spoke
The surfaces externally and internally of inner ring 23 is the face of cylinder.When tire interface ground and stress, the inner side straightway 211 at ground connection is reformed into
Raised curve, is easy to discharge in water or foreign matter.
Embodiment of the present utility model additionally provides a kind of automobile, including tire, and the tire is above-mentioned air-free tyre.
Because the air-free tyre has above-mentioned technique effect, the automobile comprising the air-free tyre should also have identical technique effect.
Construction of the present utility model, feature and action effect is described in detail according to the embodiment shown in schema above, with
Upper described is only preferred embodiment of the present utility model, but the utility model is not to limit practical range shown in drawing, it is every according to
According to the made change of conception of the present utility model, or the Equivalent embodiments of equivalent variations are revised as, still without departing from specification and figure
Show covered it is spiritual when, all should be in protection domain of the present utility model.
