Description

a bicycle tire

technical field

The utility model relates to a tire, in particular to a bicycle tire.

Background technique

Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on metal rims, it can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, which shows the ability of tires to consume rubber.

Tires are usually composed of three parts: outer tire, inner tube, and cushion belt. There are also those that do not need an inner tube. The inner layer of the carcass has a rubber layer with good airtightness and needs to be equipped with a special rim. The structure of tires all over the world is developing towards tubeless, radial structure, flat (the ratio of tire section height to width is small) and lightweight.

The outer tire is composed of a carcass, a buffer layer (or a belt layer), a tread, a sidewall and a bead. The profile of the tire casing can be divided into several separate areas: the crown area, the shoulder area (tread slope), the flex area (sidewall area), the reinforcement area and the bead area. ① carcass: also known as carcass. It usually refers to the force-bearing structure of (as) a pneumatic tire composed of one or several layers of ply (with strength, softness and elasticity) and bead.

Ply: It is a cloth layer composed of parallel rubberized cords in the carcass, and is the stressed skeleton layer of the tire to ensure the necessary strength and dimensional stability of the tire.

Bead: The part of the tire mounted on the rim, consisting of bead core, ply wrapping and chafer cloth. It can bear the tensile force caused by internal pressure, and at the same time, it can overcome the lateral force of the tire when it is turning, so that the outer tire will not come out of the rim. Therefore, it must have high strength, and the structure should be tight and firm, and it should not be easily deformed.

The carcass needs to have sufficient strength and elasticity to withstand strong vibrations and impacts, and to withstand multiple deformations caused by the radial, lateral, and circumferential forces that the tire acts on the tire during driving. The carcass consists of one or more layers of rubberized cords that give the carcass and the entire tire the necessary strength.

②Buffer layer (or belt layer): the rubber ply or rubber layer between the tread and the carcass of the bias tire, which does not extend to the middle material layer of the bead. It is used to buffer external impact, protect the carcass, and improve the adhesion between the tread and the ply. The buffer layer of the radial structure tire is generally called the belt layer because of its different functions. Under the tread base of radial tires, there is no layer of material that tightens the carcass in the circumferential direction of the centerline of the crown.

③Tread: The outermost rubber layer of the tire that is in contact with the road surface (usually, the tire crown, the outer shoulder: the edge parts on both sides of the crown, the sidewall, and the outermost rubber in the reinforced area are collectively referred to as tread rubber).

The tread is used to prevent the carcass from mechanical damage and early wear, to transmit the traction and braking force of the car to the road surface, to increase the grip between the tire and the road surface (soil), and to absorb the vibration of the tire during operation.

The part of the tire that is in direct contact with the road during normal driving is called the driving surface. The surface of the driving surface is composed of pattern blocks and pattern grooves of different shapes, and the protruding part is a pattern block. The surface of the pattern blocks can increase the gripping force of the tire and the road (soil) and ensure the necessary anti-skid force of the vehicle. The lower layer of the groove is called the base of the tread, which is used to cushion shocks and impacts.

④The sidewall is the rubber layer on the outer layer of the tire side ply, which is used to protect the carcass and is elastic.

⑤The bead is the part where the tire is installed on the rim. It is composed of a bead core and a chafer cloth, which plays a role in fixing the tire. The specifications of the tire are expressed by dimensions such as the outer diameter of the tire D, the inner diameter of the bead or the diameter of the rim d, the section width B, and the flat ratio (tire section height H/tire section width B), and the unit is generally inches (in) (lin=2.54 cm). Tire heel: The part where the outside of the bead meets the rounded corner of the bead seat of the rim. Bead core: The portion of the bead made of steel rim, apex and flipper. Traveler: A rigid ring of wound copper-plated steel wire that is the primary component that secures the tire to the rim. Assembly line: A single or multi-ring rubber rib molded at the junction of the sidewall and the bead, usually used to indicate that the tire is correctly assembled on the rim.

At present, the performance bicycle tires on the market will often touch and rub against obstacles when they are in use, which can easily cause the tires to be scratched and cause potential safety hazards.
