Embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only explaining The utility model, is not used to limit the utility model.

Embodiment

As shown in Figures 1 to 9, the utility model discloses a kind of commuting Mountain bike tire tread decorative pattern.In Fig. 1, Vertical direction is set as tire radially, and horizontal direction is set as tire axial direction, and single dotted broken line represents equatorial plane；In figure 3, CL Represent circumferential line, arrow is oriented to tire rotating direction.

As shown in Fig. 1 the section structure diagram of the utility model tire carcass 1, carcass 1 is included to be prolonged along circle The tyre surface 2 stretched, a pair of of tyre bead 3 and tire lip 4 are set in 2 both sides of tyre surface respectively.As shown in figure 3, tread base 20 is divided into center Portion M and two shoulder portion S, central portion M (region limited in Fig. 3 between two dotted lines) using circumferential line CL be it is symmetrical, its Spreading width W is the 75%-90% of tread base overall width TW.The present embodiment central portion mixing set fine and closely woven convex and Invaginated type decorative pattern, and the pattern block on tire shoulder 24 of convex is then provided at circumferentially spaced in two shoulder portion S along tire.

Specifically as shown in Figure 2-5, central portion M is divided into using circumferential line CL as symmetrical recess M1 and positioned at recessed The convex portion M2 of portion M1 two sides, the spreading width W1 of recess M1 are arranged to the 15%-30% of tread base overall width TW.In recess Set in M1 and stria 21 is crosslinked for starting point is radially concave downwards with tread base 20, crosslinking stria 21 is by multiple intensive It is connected with each other, the stria of perforation composition, is respectively 90 ° to the joint angle between lower recess stria.

The design of crosslinking stria 21 makes 20 surface of recess M1 tread bases that a variety of polygon textures with right angle, this reality be presented Apply in example, crosslinking stria 21 makes 20 surface of recess M1 tread bases that the texture similar to spliced Tetris be presented.Crosslinking Stria 21 can reduce the weight of tire, also can fully penetrated the ground pressure of scattered tyre surface 2, increase are helped into the gap on road surface Intensive contact surface with ground is to lift earth-grasping force, and the crosslinking stria 21 at right angle increases axial marginal element, there is provided one Fixed braking ability.

The cup depth h1 of crosslinking stria 21 is arranged to 0.2mm-0.5mm, and the width W2 of each stria is arranged to 0.3mm- The extra large ratio of the crosslinking stria 21 of 0.6mm, recess M1 is set as 40%-60%.The area of definition crosslinking stria 21 is ocean area, It is land area that definition crosslinking stria 21, which sets the area of the surface texture of back recesses M1, face of the sea than being defined as crosslinking stria 21 Product and the ratio of the recess M1 gross areas.If cup depth h1 is too small or slot width W2 is narrow, sea is than too small, crosslinking stria 21 The texture that more broken lines are produced in tread base 20 can not be in gap of the fully penetrated to road surface, and distributed grounding pressure and increase grab ground Power it is ineffective；Separately because of the lightweight requirements for the Mountain bike tire that commutes, its tire carcass thickness is relatively thin, if crosslinking stria 21 cup depth h1 are excessive or slot width W2 is wide, then sea is than excessive, it will largely weaken the recess M1 tires of central portion M Face rigidity, can aggravate the compression of tread base 20 on the contrary, increase energy expenditure and then increase rolling resistance.
