Description

Aromatic polyamide fiber braid and tire covering the tire of the aromatic polyamide fiber braid

The present invention relates to an aromatic polyamide fiber braid and a tire comprising the same, in particular to a tire with a low elongation and high elastic recovery of a bead coated with an aromatic polyamide fiber braid. .

In order to make the tires run on the road, the tires are not detached from the rim due to uneven road surface conditions. Most of the tire's bead is covered with steel wire. The low elongation of the steel wire improves the rubber tire lip. Air density and stability against the rim frame.

Uneven road conditions such as potholes, curb seams or bulges, manhole covers, etc. are inevitable, especially for small tires, among which bicycles are the most important. Compared with other vehicles, the tire tire has the thinnest sidewall and the narrowest tread, and the tire has the smallest inflation space. When the road surface condition is not good, the bicycle tire can buffer the impact space and disperse the impact force. The smallest area, and most susceptible to road conditions, is also the most prone to detachment of the rim from the tire.

However, in recent years, as oil prices have risen and parking spaces are hard to find, many people have turned to bicycles that do not require the use of gasoline and are less space-consuming, and the riding of bicycles as a leisure or sport. Improvements to various parts of the bicycle become more and more people Research and development topics.

Since the road surface condition is uncontrollable, in order to avoid damage or deformation of the tire, it is an inevitable trend that the bicycle is equipped with a spare tire. However, the steel wire covered by the tire's bead is originally intended to strengthen the adhesion between the bead and the rim, and this has become a limitation on the spare tire.

In order to make the spare tire easy to carry, and then consider the bicycle storage space and the weight of the load is limited, the spare tire of the bicycle must have the advantages of light weight and small volume. In practice, the most straightforward way to reduce the spare tire volume is to fold the tire, but because the tire is covered with steel wire, and the angle at which the steel wire can be bent is limited, the tire is greatly limited in folding. In addition, the steel wire will be creased after being bent, which will affect the airtightness of the bead and the rim, and it is easy to cause the occurrence of the tire or the air leakage and affect the driving safety. Furthermore, the use of steel wire tires is heavier and is a drawback for tires that have a lighter weight requirement.

The reason is that, in view of the problems of the conventional tires, in order to be able to solve the problem, the creator based on years of research and development and many practical experience, proposed an aromatic polyamide fiber braid and fetal lip coated aromatic poly A tire of a polyamide fiber braid is used as an implementation and basis for improving the above disadvantages.

In view of the above-mentioned problems of the prior art, one of the aims of the present invention is to provide an aramid fiber woven fabric which can be used in the tire lip of a tire to solve the limitation of the folding size of the tire and the bead and the wheel after folding. The problem of poor density of the air and the need to reduce the weight of the tire.

For the purposes of this creation, this creation proposes an aramid fiber braid for tires of tires. The braid comprises at least one core wire and at least one covered wire, wherein the core wire and the covered wire are bundles of aromatic polyamide fibers, and the covered wire is interwoven by a braiding machine to form the braid on the outside of the core wire, and the foregoing The bead covers the braid.

Preferably, the aforementioned aromatic polyamide fiber bundle has an elongation of from 0.1% to 3%.

Preferably, the aforementioned aromatic polyamide fiber bundle is preferably a bulletproof fiber bundle.

In addition, the present invention further provides a tire-covered aramid fiber braided tire comprising a tire body and at least one braid body. The tire body comprises a tread, a second sidewall and a second fetal lip, one side of the tread is provided with a pattern, and the other side of the opposite pattern is provided with at least one airtight layer. The second sidewalls are tapered from the sides of the tread toward the inner liner, and the second sidewall and the tread form a hollow annular body having an opening toward the center. The second fetal lips are respectively located at one side edge of each of the sidewalls to form an opening for sealing against the frame of the rim, and the opening is covered by the frame of the rim, and the airtight layer and the frame of the rim form a gas chamber. The braid body is wrapped in the bead, and comprises at least one core wire, that is, at least one covered wire, and the core wire and the covered wire are bundles of aromatic polyamide fibers, and the covered wire is interwoven and wrapped on the core wire by a braiding machine. The outer portion forms the braid body. When the tire body is sleeved on the rim and the air chamber is filled with the inflatable body, the bead is tightly abutted against the frame of the rim by the braid body, so that the gas is sealed in the air chamber.

Preferably, the aforementioned aromatic polyamide fiber bundle has an elongation of from 0.1% to 3%.

Preferably, the aforementioned aromatic polyamide fiber bundle may be a bulletproof fiber bundle.

In the present invention, in the above-mentioned aromatic polyamide fiber woven fabric, deformation can be generated by bending external force, and when the bending external force is removed, the woven fabric returns to the state before deformation by the elastic restoring force. Further, the braid can be deformed by stretching by a tensile external force, and when the tensile external force is removed, the braid is returned to the state before the deformation by the tensile resistance. In the tire in which the bead is coated with the above-mentioned aromatic polyamide fiber braid, the tire is folded by bending external force, and when the bending external force is removed, the bead returns to the deformation state by the elastic restoring force of the braid body. State. And after the tire is folded and restored to the state before the deformation, the tensile force is stretched and set on the frame of the rim, and the tire is pulled. The external force causes the bead to deform. When the external force is removed, the bead returns to the state before the deformation by the tensile strength of the braid body, and closely adheres to the frame of the rim.

According to the above description, the aromatic polyamide fiber woven fabric of the present invention and the tire-covered tire of the aromatic polyamide fiber woven fabric have the following advantages:

(1) The aromatic polyamide fiber woven fabric and the tire-covered tire of the aromatic polyamide fiber woven fabric are replaced with an aromatic polyamide fiber woven fabric to reduce the weight of the tire.

(2) The tire of the aromatic polyamide fiber braid and the tire covering the aromatic polyamide fiber braid, the bending angle of the bead of the braid or the tire is obtained by the bending property of the fiber after weaving Unrestricted, thereby reducing the restriction of the folding of the tire, so that the volume of the tire can be minimized by folding.

(3) The tire of the aromatic polyamide fiber woven fabric and the tire-covered fabric of the aromatic polyamide fiber woven fabric, which has a high elastic recovery property after being woven by the aromatic polyamide fiber bundle When re-expanding after bending, there will be no creases on the fiber bundle, so that the shape of the bead will not be changed by folding the tire, and the adhesion of the bead to the rim can be ensured without the tire folding. influences.

(4) The tire of the aromatic polyamide fiber braid and the tire covering the aromatic polyamide fiber braid, the bead and the rim by the low elongation property of the aromatic polyamide fiber bundle The pressure of the abutment is not changed by the folding of the tire and the action of stretching or stretching the tire on the rim, ensuring the airtightness of the tire air chamber.
