Description

Tire construction

[technical field]

The utility model relates to a kind of tire construction, and it is relevant with general tire especially to refer to a kind of, particularly reduces the tire construction of the disappointing possibility of bike tyre.

[background technology]

Known bike tyre is directly to be assembled on the wheel rim, and is available for users to the usefulness that drives.

And general known bike tyre is when driving; usually can be subjected to push improperly; often occur in and when tire fills full gas, be subjected to the object that protrudes; for example: rock, ridge ... or the like impact; cause tire to be extruded rapidly; and tire is between compression period, causes the inner tube of a tyre to be extruded between hard edge of wheel rim and the object that causes impacting, even pierce through the inner tube of a tyre at last and cause losing heart of tire.

Though, the dealer can be by increasing the thickness of whole tyre edge, so that the intensity of tyre edge increases, further can reduce the degree that tire is extruded, but this measure will increase the weight of whole tire, and cause the too stiff and forfeiture of tire original on controlling the flexible ability of due each landform of adaptation, and increase productive costs and material, so generally can not adopt.

Perhaps the dealer considers to increase tire flap (curtain yarn density), and then the concentrated zone that can scatter one's forces, but it also has the shortcoming that increases great amount of cost.

Though and tubeless tire construction does not have the inner tube of a tyre, but convert this tyre type (tubeless tires structure) to, then must buy the tire of particular design and the wheel rim of collocation thereof, also do not have an economic and practical; In addition, the wheel ring cross-section squeezes the moulding that type can be designed to scatter one's forces, and it also has the problem of its applicability and the cost of deriving.

In addition, general tire is shed to outside the wheel rim because of some situations sometimes unexpectedly, please cooperate and consult Fig. 3 to shown in Figure 5, array mode for known tire, it comprises a wheel rim 30 and a tire 40, the open sides near-end edge place of this tire 40 has a tyre bead portion 41 respectively, and the end of the open sides of this tire 40 has a tire lip 42 respectively, the inner tube of a tyre 50 is placed this tire 40 inside, and 42 groups on the tire lip that utilizes tire 40 is gone in the groove 31 of wheel rim 30, when filling full gas then, because the cause of air pressure, groove 31 inner faces and the tire lip 42 of wheel rim 30 combined closely (tubeless tires structure also herewith principle);

Yet, when tire 40 in some painstakingly under the bevelled situation (as the fancy performance or cross when curved), tyre bead portion 41 is extruded distortion causes tire lip 42 to come off from the groove 31 of wheel rim 30 easily, and precipitate like this coming off controlled safety (as Fig. 3 and shown in Figure 5) with what have a strong impact on bicycle.

Though, the pipe tire there is no the doubt of this obscission under normal mounting, but problem is that the pipe tire mainly is directly to be sewn into the inner tube of a tyre in the tire, in case when blowing out, be only to repair, and must change in the lump, therefore together with cover tire at the inner tube of a tyre, under the prerequisite of considering cost, these structures also can't solve the above-mentioned problem that comes off.

Moreover, the problem that tire may occur when bicycle drove is that tire and wheel rim rotate asynchronously, and can produce slightly slide relative, be so-called slippage (Slipping), the Regular Bicycle brake system is to utilize to check wheel rim, also stops operating simultaneously to cause the tire that is installed on it, but under certain speed, stop the stopping time, stopped though wheel rim has stopped, because the cause of force of inertia, tire will continue to rotate independently to rub until ground and exhaust its kinetic energy.When this slippage (Slipping) phenomenon takes place, it will cause the bicycle driver effectively to control, and then influence it and drive safety.And such slippage (Slipping) situation may occur in tube-tyre structure and the tubeless tires structure simultaneously.

And, will cause wheel rim to peel off inner tube of a tyre valve lever and inner tube of a tyre joint at last owing to the relative dislocation of wheel rim with tire (inner tube of a tyre and cover tire), and cause losing heart of tire.

Though the tubeless tires structure does not have the inner tube of a tyre, as previously mentioned, convert the tubeless tires structure to, must buy the tire of particular design and the wheel rim of collocation thereof, therefore under the prerequisite of considering cost, it also can't address the above problem.
