Tire 1 tyre surface 10 inclination grooves 11
The specific embodiment
Explain the specific embodiment of the present utility model below in conjunction with accompanying drawing 1-10:
Be illustrated in figure 1 as Electrical Bicycle tire 1 of the present utility model, it is divided into 3 zones with tire protector 10 along tyre surface arc orientation average, comprises a central area A, two symmetrical transitional region B, reaches two symmetrical shoulder zone C.Generally be filled with the Electrical Bicycle tire of standard blast, the zone that contacts with ground when straight-line travelling is mainly central area A.Therefore because the common angle of turn of Electrical Bicycle is less, and moving velocity can be too not high, and tire contacts with ground when turning is mainly transitional region B, and shoulder zone C only just can be touched when turn sharp.
Cooperate Fig. 2 to shown in Figure 6, Electrical Bicycle tire of the present utility model, its both sides at tyre surface 10 circumferential line of centerss are provided with several uniform inclination grooves 11, be provided with cross groove 12 between the adjacent two inclination grooves 11, between each cross groove 12 and inclination groove 11, be provided with branch's groove 13; These inclination groove 11 upper ends extend to central area A, and tread edge is run through in the lower end, it should be noted that: upper and lower side herein is the direction of advancing with tire and defining, and the upside down end of inclination groove 11 is the design that broadens gradually; The upper end that the design that is in the shape of the letter V of this cross groove 12, its inner extend to central area A and inclination groove 11 connects, and tyre surface 10 edges and 11 perforations of inclination groove are run through in the outer end; This branch's groove 13 is the inverted L shape design of inclination, and its upper end connects with the nearly middle part of inclination groove 11, and the nearly inner end of its lower end cross groove 12 connects, and kink 131 extends to the boundary line of regional A and regional B; Behind inclination groove 11, cross groove 12 and the branch's groove 13 tyre surface 10 is divided into three main pattern blocks: core piece 20, transition pattern block 21, pattern block on tire shoulder 22(are as shown in Figure 6).
As shown in Figure 2, the inclination groove 11 that arranges in the circumferential line of centers both sides of tyre surface 10 adopts longitudinally design of height, the α that has angle of itself and the circumferential line of centers of tire, and angle α designs less than 45 °.The inner of inclination groove extends to central area A, and tread edge is run through in the outer end, and the inner broadens gradually towards the outer end.Inclination decorative pattern height is angle design and all can be effectively water be discharged towards the tread edge design that broadens gradually longitudinally, improves the wetland performance of tire.
As shown in Figure 3, the cross groove 12 that arranges in tyre surface 10 circumferential line of centers both sides, intert between inclination groove 11, and the groove after the mutual perforation of the two is inner to form a distance L 1(as shown in Figure 4 to the circumferential line of centers of tire), L1 is set to 30% ~ 45% central area A width.If it is too little that L1 arranges, the circumferential decorative pattern in tyre surface 10 centers can be cut into fritter, cause this land, zone than too small, the circumferential creeping deformation of decorative pattern was large when tire was kept straight on, and namely rolling resistance increases; If it is too large that L1 arranges, this land, zone is than excessive, and it is done, earth-catching property and the drainage performance of wetland will be affected.
As shown in Figure 5, be arranged between inclination groove 11 and the cross groove 12 at branch's groove 13 of transitional region B, part extends to the boundary line of regional A and regional B, and the land ratio with balance transitional region B reduces the generation of irregular abrasion phenomenon.And the core piece 20 that tyre surface is divided into, transition pattern block 21, pattern block on tire shoulder 22, it is that core piece 20 edges are continuous zig-zag or the shape of other concavo-convex drops, the ground contact area of continuity decorative pattern is large, can effectively reduce rolling resistance; The design of zig-zag edge, the edge effect of enhancing tire, the earth-catching property of raising vehicle; In addition, transition pattern block 21, pattern block on tire shoulder 22 are all the fitfull polygon, and this two pattern block to move towards setting consistent with the working direction of tire, promote the drainage performance of tread contour.
As shown in Figure 7, for further promoting the Combination property of tire, sharp-pointed outshot 201 at serrated center pattern block 20 is provided with the with it parallel short ditch 20a in edge, this short ditch 20a adopts inverted triangle taper designs (such as Fig. 8), and its degree of depth h1 is 30% ~ 50% inclination groove 11 or the depth H of branch's groove 13.The stress that the arranging of short ditch 20a can be reduced core piece 20 sharp-pointed outshots 201 is concentrated, and avoids premature wear, and the inverted triangle cone do not lose the pattern block rigidity when reducing the land ratio, does not namely affect the rolling resistance performance.The recessed portion of core piece 20 is comparatively weak, one connection rib 21a can be set between recessed portion and pattern block 21, it is arranged on the bottom of trench of branch's groove 13, the cross section of this connection rib 21a is step (shown in Fig. 8,9), the top of connection rib 21a is first step 21c, and base portion is second step 21d.Connection rib 21a height h2 is set to greater than 50% inclination groove 11 or the depth H of branch's groove 13, and wherein the height h3 of first step 21c is 30% ~ 70% of connection rib 21a height h2; And first step 21c length L 3 is set to the length L 2 of 30% ~ 70% second step 21d.Step connection rib 21a only increases weight seldom, but can obviously promote the boundary intensity of central area A and transitional region B, and promotes the whole feel of tire.At transition pattern block 21 configuration shallow ridges 21b, shallow ridges 21b can improve transition pattern block 21 elasticity, thereby increases the tractive force of tire, laterally breaks away when preventing from turning; Downward-sloping and run through the shallow ridges 22a at tyre surface 10 edges from cross groove 12 bottoms in pattern block on tire shoulder 22 configuration, this shallow ridges 22a complies with the tire working direction, to improve the drainage performance of shoulder zone C.Simultaneously, arranging of shallow ridges 21b, 22a all reduced tire weight.
In addition, can be at transition pattern block 21 or the thin decorative pattern group of pattern block on tire shoulder 22 surface configuration 22b, this thin decorative pattern group is the suitable shape that triangle cone, quadrangular pyramid body etc. can alligatoring pattern block surfaces, to improve at turn sharp or tempo turn earth-catching property, increases the safety of driving.
Comprehensive above design, the total land of tyre surface 10 decorative patterns of the utility model tire is than (with the ground plane area on pattern block surface as land area, the ditch area of pattern block is as the ocean area, and the land is than the ratio for the ground plane area on pattern block surface and this zone gross area) maintain: 60% ~ 70% is advisable.And, configure respectively tyre surface 10 each regional optimum land than as follows:
Central area A:85% ~ 95%
Transitional region B:55% ~ 65%
Shoulder zone C:50% ~ 60%
The scheme that the utility model tire discloses not only can be used as the structural improvement of Electrical Bicycle tire, also can be used as bike tyre and uses, and all can reach aforesaid result of use.
Embodiment:
The below uses embodiment to be described in further details.
Tire size: 16X1.95
Following table is depicted as the result who tests, compares gained by the design that will have Electrical Bicycle tire decorative pattern now and the utility model example tire, adopts desired value as metewand, and numerical value is larger, and performance is better.
Key point of the present utility model is to optimize the tire tread pattern method of designing, and tire protector is divided into some zones, and is different according to the effect in each zone of tyre surface, configures suitable decorative pattern combination and land ratio.
