Abstract
The invention relate to a novel light bicycle tire which comprises a left tire bead portion, a right tire bead portion, side wall portions and a tire tread portion. The side wall portions extend from the tire bead portions to the radial outer side of the tire, and the tire tread portion is in bridge connection with the two side wall portions. The tire tread portion comprises a crown in contact with the ground and tire shoulders connected with the side wall portions. The novel light bicycle tire further comprises a cord fabric layer folded back to wrap the tire bead portions for a circle, and the edge of the cord fabric layer is folded upwards around a bead core to be anchored in the two tire shoulders in a wrapping mode. The tire tread portion comprises a reinforced cord fabric layer and a tire tread layer which are sequentially on the outer side of the cord fabric layer and annularly arranged in the circumferential direction of the tire, and the reinforced cord fabric layer and the cord fabric layer are arranged on the two tire shoulders in an overlapped mode. The cord fabric layer is folded to wrap the tire bead portions for a circle, and the reinforced cord fabric layer arranged on the outer side of the cord fabric layer is used in combination, so that the tire tread portion is divided into two layers, and the tire side portion is divided into two layers; under the condition of reducing the weight of the tire, the safety and durability of the tire are also guaranteed, weight reduction of the bicycle tire is achieved, and the requirement for riding comfort is met.
Description
Technical field
The present invention relates to a kind of tire, particularly relate to a kind of Novel lightweight bike tyre.
Background technology
Along with self-propelled vehicle gets more and more, the congestion in road in city grows in intensity, and motor vehicle exhaust emission has also become urban air primary pollution source, and in order to alleviate the motor vehicle exhaust emission in urban traffic pressure and minimizing urban district, government more and more advocates Green Travel.
In prior art, bike tyre mainly contains following two kinds of structures: one is turned back overlapping after parcel bead part by one deck carcass plies, forms fetus face 3 layers of carcass plies, 2 layers, sidewall portion carcass plies; Two is turned back not overlapping after parcel bead part by two layers of carcass plies, and sidewall portion is fixed at the place of turning back, and forms tyre surface 2 layers of carcass plies, 4 layers, sidewall portion carcass plies.The weight of above-mentioned two kinds of bike tyres is light not, can not meet the demand of people.
Therefore, the comfortable bicycle of a kind of light weight is more needed badly.
Summary of the invention
The object of the invention is the defect overcoming prior art existence, a kind of Novel lightweight bike tyre is provided.
The technical scheme realizing the object of the invention is: a kind of Novel lightweight bike tyre, comprise a left side, right pair of bead portion, the fetus face in the sidewall portion extended from bead part towards tire radial outside and bridge joint two sidewall portions, described fetus face comprises and the crown of earth surface and the tire shoulder that is connected with sidewall portion, it is characterized in that, also comprise the carcass plies that the described bead part of parcel of turning back forms a week, upwards to turn back parcel and be anchored in two tire shoulders around bead core in the edge of described carcass plies, described fetus face comprises and to be set in turn in outside described carcass plies and the reinforcement carcass plies that arranges along tire circumference of ring-type and tread ply, described reinforcement carcass plies and described carcass plies overlap at two tire shoulder places, the edge of described carcass plies is upwards also provided with anti-friction layer in the place of turning back around bead core.
Further, described anti-friction layer is nylon interlaced yarns, and the density of described anti-friction layer is per square inch between 20 × 20 to 60 × 60.
Further, described carcass plies and reinforcement carcass plies are nylon oblique curtain yarn layer, and the density of described carcass plies and reinforcement carcass plies is per square inch between 30 to 120.
Further, described bead core is bead coil or the KEVLAR fibrous loop of diameter 0.95mm.
Further, the described two ends of reinforcement carcass plies in the direction of the width and/or in circumference are for no reason.
Further, the tension member being arranged at bead part around bead core ring-type is also comprised.
Further, described tension member is steel cord.
Further, described tension member outer application has rubber layer or resin bed.
Further, the two ends of described tension member in the direction of the width and/or in circumference are for no reason.
The present invention has positive effect: carcass plies is turned back and wrapped up bead part formation one week, in conjunction with the reinforcement carcass plies be arranged at outside carcass plies, tyre surface position is made to be two-layer, position, sidewall is two-layer, when reducing tire weight, ensure that safety and the durability of tire equally, realize the lightweight of bike tyre, meet the comfort level demand of riding.
Accompanying drawing explanation
In order to make content of the present invention more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation, wherein:
Fig. 1 is structural representation of the present invention.
Wherein: 1, carcass plies, 2, reinforcement carcass plies, 3, bead core, 4, anti-friction layer, 5, tread ply.
Detailed description of the invention
As shown in Figure 1, the present invention, a kind of Novel lightweight bike tyre, one of them embodiment, comprise a left side, right pair of bead portion, the fetus face in the sidewall portion extended from bead part towards tire radial outside and bridge joint two sidewall portions, fetus face comprises and the crown of earth surface and the tire shoulder that is connected with sidewall portion, also comprise the carcass plies 1 that parcel bead part of turning back forms a week, upwards to turn back parcel and be anchored in two tire shoulders around bead core 3 in the edge of carcass plies 1, fetus face comprises and to be set in turn in outside carcass plies and the reinforcement carcass plies 2 that arranges along tire circumference of ring-type and tread ply 5, reinforcement carcass plies 2 and carcass plies 1 overlap at two tire shoulder places, the edge of carcass plies 1 is also provided with anti-friction layer 4 around bead core 3 parcel place of upwards turning back.
According to actual conditions, can select, carcass plies 1 and reinforcement carcass plies 2 are nylon oblique curtain yarn layer, and the density of carcass plies 1 and reinforcement carcass plies 2 is per square inch between 30 to 120; Bead core 3 is bead coil or the KEVLAR fibrous loop of diameter 0.95mm; Anti-friction layer 4 is nylon interlaced yarns, and the density of anti-friction layer 4 is per square inch between 20 × 20 to 60 × 60.
