The specific embodiment
Explain embodiments of the present invention below in conjunction with accompanying drawing:
As Fig. 2, Fig. 3, shown in Figure 4, the present invention has disclosed a kind of evil road all-terrain vehicle air tread structure, and this tire protector 1 is divided into the shoulder zone B of central area A and both sides, and the width of central area A is 1/2 of tread contour overall width TW.Central area A comprises the core piece 10 of circumferentially arranging, and the shoulder zone B of both sides comprises the shoulder pattern block 30 of circumferentially arranging, the set-up mode that middle pattern block 20 adopts across the shoulder zone B of central area A and both sides.
Key of the present invention is: circumferentially be extended with the first enhancing portion 40 along its base portion in the spoil disposal passage in the middle of each between the pattern block 20, this first enhancing portion 40 can connect adjacent middle pattern block 20, lean between the axially inboard base portion spoil disposal passage with shoulder pattern block 30 at middle pattern block 20 simultaneously the second enhancing portion 50 that is connected the two is set, this first enhancing portion 40 can strengthen piece 41 by fitfull first and constitute, and this second enhancing portion 50 strengthens piece 51 by a plurality of fitfulls second and constitutes; First end face that strengthens piece 41, the second enhancing piece 51 adopts dip plane 411,511 that (seeing Fig. 5, shown in Figure 6) is set respectively, each dip plane 411, the 511st, and mind-set tire shoulder direction is the setting of top-down inclined-plane in tyre surface.So arrange by fitfull first strengthen the first enhancing portion 40 that piece 41 constitutes, by a plurality of fitfulls second strengthen the second enhancing portion 50 that pieces 51 constitute can effectively prevent tire in the process of moving the shoulder zone in the ground connection outside destroyed by the foreign object puncture.As shown in Figure 8, the first enhancing portion 40 also can be made up of a plurality of first enhancing pieces 41.As Fig. 9, shown in Figure 10, the first enhancing portion 40, the second enhancing portion 50 can be along tire and circumferentially are the setting of continuous or discrete interval.
