A. of tire 100.
In addition, tire 100 has a pair of reinforcement plies 160, each is in a side of tire 100 and be arranged in tire shoulder portion 135. as shown in Figure 1, each reinforcement plies 160 extends to the radially inner side of crown plies 150 from side wall portion 115. and reinforcement plies 160 shown in Figure 1 is in body piles 140 radially outer positions, but, it should be understood that, reinforcement plies 160 is in body piles 140 radially inner sides location also within the spirit and scope of the present invention. and reinforcement plies 160 extends predetermined distance d towards crown part 110, and the axial edge 165. of crossing radially interior crown plies 150 preferably, predetermined distance d is greater than 10mm, but can be according to such as other factors such as manufacturing process or the tyre performance except pinch shock and longer. reinforcement plies 160 also extends preset distance f towards side wall portion 115, and the axial edge 165. of crossing radially interior crown plies 150 preferably, preset distance f is 25mm at least, but can be according to such as other factorses such as manufacturing process or the tyre performance except pinch shock and longer. in other embodiments of the invention, apart from the length of f 25mm at least, but be no more than the length that reinforcement plies 160 is crossed tire equator E. as body piles 140, reinforcement plies 160 is formed by many textile cords usually, cord is by such as polyester, nylon, aramid, the combination of regenerated fiber or these textile materials is made. as carcass layer end 145, reinforcement plies 160 provides extra reinforcement in tire 100, opposing destroys or pinch shock when extruding occurring between wheel rim and road surface.
Utilize finite element method, the applicant has studied the influence of the angle of the cord in the relative body piles 140 of cord that changes in the reinforcement plies 160 to the opposing pinch shock.Normally used rubbery material is in fact incompressible in tire construction.As a result, when these materials are extruded, for example producing under the condition of pinch shock between wheel rim and road surface, rubber causes the force direction expansion of extruding in approximate vertical.According to displacement, the cord in the tire may rupture, and is called pinch shock here.The applicant determined, by with the cord of reinforcement plies 160 by the mode orientation that is basically parallel to body piles 140, can produce reinforced tire 100 and increase its maximum effect the pinch shock opposing.But this parallel orientation is unfavorable to some application, for example needs to increase the application of lateral stability.Therefore, the applicant determines, can use the angle except that parallel orientation between the cord of body piles 140 and reinforcement plies 160, and the tire construction of opposing pinch shock still can be provided simultaneously.
Below with reference to the diagram of curves of Fig. 7, the cord that the x axle represents to constitute reinforcement plies 160 is the angle of the horizontal surface of the S. A. by tire 100 relatively.For example, an angle of 90 degrees is represented the horizontal surface of the cord of reinforcement plies perpendicular to the S. A. that passes through tire 100.Under this orientation, the cord of body piles 140 and reinforcement plies 160 is parallel to each other substantially.Curve y axle among Fig. 7 represents to stand the interior application force ratio of tire specific part of finite element analysis.This specific part is the choice of location that occurs the pinch shock effect from the tire shoulder portion 135 interior expections usually of tire 100.The ratio that the y axle is represented is:
R＝(F
rp/F
0)*100
In the formula, F
Rp=have a tensile force that reinforcement plies stands
F
0=the tensile force that do not have reinforcement plies to stand
In order to make the tensile force minimum that causes pinch shock, need reduce R or make its minimum.Shown in the curve of Fig. 7, when the cord of reinforcement plies 160 relatively the angle of the horizontal surface of the S. A. by tire 100 be 90 when spending, the R minimum.In other words, when the cord of reinforcement plies 160 is parallel to the cord that constitutes body piles 140, the R minimum.But as shown in Figure 7, the applicant determines that when angle was spent between (that is, body piles cord 0 to 20 is spent relatively) 70 to 90, reinforcement plies 160 still produces to be resisted the pinch shock acceptable.Though under the angles that are lower than 70 degree, still play some effects, when angle when reducing, provides the cost of reinforcement plies 160 to begin to surpass the benefit of resisting pinch shock since 70 degree.Therefore, when preferably less than the angle of 90 degree (may for the application of the higher lateral stability of needs), the applicant finds to utilize the present invention still can realize opposing to pinch shock.
