Description
Technical field
The invention belongs to tire filler technical fields, and in particular to a kind of non-maintaining tire filler and its user
Method.
Background technology
It is all inflated wheel that most tires, which include bike tire, in the market, motorcycle tire, automobile tire use
Tire.Pneumatic tire has the advantages that light-weight and provides soft and comfortably take, because these filling tires have gas or sky
Gas.However the major defect of pneumatic tire is deflation risk caused by piercing through, cover tire is detached with wheel rim or cover tire or wheel rim
Other failures.
There is partially self vehicle to use the solid tyre for exempting from inflation in the market.Solid tyre due to be it is solid, can it is non-aerating and
It is anti-tie, but such tire has the following problems:It is of high cost, it is not wear-resisting, shockproof properties are poor, the shortcomings of carcass weight.
Filling tire contains solid or semisolid material rather than compressed air, this eliminates deflation risk, because cover tire
It pierces through or other failures will not cause gas to leak.
Filling tires material should meet several requirements mutually to be competed with the good dynamic characteristic of pneumatic tire.For example, tire
Packing material should make tire absorb concussion and provide good tractive force.Therefore, filling tires material should be soft and flexible.This
Outside, filling tires material should make tire not gather excessive heat in use, because these heats can damage filling material
Therefore material or cover tire simultaneously reduce Life of Tyre.It is considered in addition, cost is very important.
