Description
Technical field
The present invention relates to a kind of tire, especially a kind of air-free tyre；Aforementioned no turbine is used the invention further relates to a kind of
The automobile of tire.
Background technology
Tire is mounted on automobile and contacts the component rolled with ground.Tire is not only wanted to bear as transfer pair
The vehicle load of elephant will also buffer the uneven caused traveling impact in ground.
Tire and wheel make motor racing in vehicle bridge (axis) power transmission between ground.Therefore, tire and wheel arrangement are answered
Meet following basic demands：Enough load-bearing capacities and speed ability have smaller rolling resistance and running noise, good
Attachment characteristic and mass balance, wear-resistant, resistance to puncture, ageing-resistant and good air-tightness, quality is small, price is low, it is convenient for disassembly and assembly,
Interchangeability is good.
There are many sorting techniques for tire, wherein 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；Divide passenger car by purposes difference
(referring to car, light bus) tire, commercial car (referring to lorry, motorbus) tire, off-highway wheel tire, special purpose vehicle tire；
Divide highway tread pattern tire, cross-country tread pattern tire, dual purpose tread pattern tire and extraordinary rib tire by tread contour difference；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 comfort are good；Commercial car tire size is big, and bearing capacity is strong；It is off-highway
It is good with wheel tire adhesion, the resistance to puncture of tyre surface, suitable for working under severe conditions.Highway tread pattern tire drag is small, makes an uproar
Sound is small, and suitable for being used on paved road, wherein annular ribs tire is suitable for good road surface, and transverse pattern tire is suitable for soil
Stone road surface；Cross-country tread pattern tire is suitable for bad road surface or is used without road area；Dual purpose tread pattern tire is suitable for using pavement conditions
Protean occasion.
The widely used aerated rubber tyre of present automobile, pneumatic tire are to inject compressed air in confined space to keep
The tire of cushion performance is obtained while tire shape by air pressure, wherein be divided into as tubed tyre and tubeless tyre,
Tubeless tyre is called vacuum tyre.However, there is the defect for being punctured or being difficult to keep when tearing its shape in pneumatic tire.At a high speed
When driving if pneumatic tire bursts, the operability of vehicle becomes very poor, be the reason of the major accidents such as causing to overturn it
One.
In the basic performance of tire, the elasticity of tire is extremely important.When carrying out structure mechanics analysis 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, these three elastic rings form the lateral stiffness K of tire combined with Figure 1 and Figure 2,s, radial rigidity KrWith turn
Dynamic stiffness Kt, lateral stiffness KsDetermine the lateral deviation power of tire, 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 very big.
Present air-free tyre is gradually developed, and future also will gradually use air-free tyre.Air-free tyre be it is a kind of not
The tire that support force is realized by air realizes support and the buffering of tire by substance and structure.Air-free tyre is due to it
The particularity of structure can't blow out when there is hard objects to pierce through tire as pneumatic tire, and can move on,
Greatly promote power driving safety.
Present air-free tyre is gradually developed, and future also will gradually use air-free tyre.Air-free tyre be it is a kind of not
The tire that support force is realized by air realizes support and the buffering of tire by substance and structure.Air-free tyre is taken turns
Spoke outer ring substitutes belt, substitutes sidewall with the spoke and spoke centre circle of spoke, 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 at bullet
Sexual function will substitute the spring function of three tread rubber layer of pneumatic tire, belt and sidewall elastic rings, connection wheel and
The spoke of tread rubber layer, not only want tire keep cylindrical shape, but also can bear and buffer transverse direction, radial direction and rotation when
The effect of power and torque.
Air-free tyre due to its structure particularity, have hard objects pierce through tire when, can't as pneumatic tire that
Sample is blown out, and can be moved on, and power driving safety is greatly promoted.But the tire shoulder of the pneumatic tire of the prior art is harder,
The phenomenon that easy ting produce inordinate wear, the resistance that tire shoulder generates when turning are also bigger.In addition, the foreign matters such as water, silt, stone hold
Easily enter in the gap between air-free tyre spoke, existing air-free tyre is poor to the discharge ability of foreign matter.
Application No. is disclose a kind of air-free tyre, structure in 201210458366.4 Chinese invention patent specification
As shown in figure 3, including rubber tread 500, spoke 600, outer side band 700 and inner band 800.Due to from vehicle etc. load,
Impact caused by frictional force, road pavement form from road surface, the torque etc. from wheel hub form complicated internal stress, these power
It acts on tire, so this air-free tyre has the following problems：When by road shocks, buffer capacity is poor, causes
The ride comfort of vehicle traveling is poor.
