Description
Technical field
The present invention relates to a kind of tire, particularly a kind of air-free tyre；Used the invention further relates to one kind foregoing without turbine
The automobile of tire.
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 due to it
The particularity of structure, when there is hard objects to pierce through tire, can't blow out as pneumatic tire, and can move on,
Greatly promote power driving safety.
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 tire shoulder of the pneumatic tire of prior art is harder,
The phenomenon of inordinate wear is easily produced, the resistance that tire shoulder is produced during turning is also than larger.Additionally, the foreign matter such as water, silt, stone holds
In the gap for easily entering between air-free tyre 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.
The content of the invention
