Description
Technical field
The utility model relates to a kind of tire, particularly relates 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.
Utility model content
The purpose of this utility model is the defect overcoming prior art existence, provides a kind of Novel lightweight bike tyre.
The technical scheme realizing the utility model object 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 utility model 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 utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein:
Fig. 1 is structural representation of the present utility model.
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 utility model, 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.
