Fig. 2 is the variation scheme drawing of tire ground connection impression in the turning process.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Description of reference numerals is as follows:

1---laemodipodiform decorative pattern rib 2---whale dorsal fin shape pattern block

3,3 ＇---curve groove 4---are straight flute circumferentially

The interior arc groove of 5---tire shoulder pattern ribs 6---

7,7 ＇---oblique groove 8---gripping pattern rill

The short sharp knife shape of 9---long sharp knife shape grooves 10---groove

11---anti-skidding fine groove

This tire is a kind of riding radial-ply tyre, and its tread contour is by a large amount of different circular pitches and be asymmetric decorative pattern unit, the left and right sides along circumferential overlapping forming.

As shown in Figure 1, its tyre surface is divided into the central area and adheres to the shoulder zone on both sides separately, wherein the central area is made up of the continuous laemodipodiform decorative pattern rib 1 in tire center and the whale dorsal fin shape pattern block 2 of both sides, the both sides of laemodipodiform decorative pattern rib 1 are the continuous circumferential mutual dislocation of concave shaped and edge, consistent with the dislocation mode of both sides whale dorsal fin shape pattern block 2, between the whale dorsal fin shape pattern block 2 and and laemodipodiform decorative pattern rib 1 between the curve groove 3 that forms, 3 ＇ are in conjunction with being the bow type, and twice continuous circumferential straight flute 4 in the left and right sides is formed shoulder zone with the tire shoulder pattern rib 5 on both sides respectively, according to the tire size size, it specifically is exactly different tread widths, article two, circumferential straight flute 4 should distribute with suitable furrow width and location interval, the applicant is optimum when repetition test confirms that the value of correlation parameter is set by following scope: the width of central area is 0.43～0.47 (0.455) with the ratio of tread width, the ratio 0.43～0.47 (0.455) of the width of tire shoulder pattern rib and tread width, the width of the circumferential straight flute of left and right sides twice is 10～16mm (15mm), and the numerical value in its bracket is the actual value of present embodiment.Thereby above-mentioned two broad circumferential straight flutes can be fast effectively draining improved the wetland tractive force and prevented neatly, the central area can substantially improve tyre revolution to precision, strengthen the road-holding property of exercises such as directly advancing, whale dorsal fin shape pattern block can be easily and is punctured moisture film effectively, water dumping rapidly, greatly improved tire ground hydroplaning phenomena, under wet and slippery pavement conditions, give tire splendid handling, the curve groove makes the tire ground connection and the transmission of power in the process of moving more level and smooth, can reduce noise and improve traveling comfort to improve abrasion uneven.

As shown in Figure 1, whale dorsal fin shape pattern block 2 has the interior arc groove 6 that extends inwards from outside straight flange middle part, its radian is consistent with the curve groove 3 between the whale dorsal fin shape pattern block, whale dorsal fin shape pattern block 2 also has the oblique groove 7 that extends to interior arc groove 6 from arc limit, both sides inwards, 7 ＇, two oblique groove mutual dislocation also distribute at an angle with horizon, whale dorsal fin shape pattern block is divided into three little piecemeals, two little piecemeals in the outside have the gripping pattern rill 8 that extends inwards from straight flange middle part, and its radian is consistent with interior arc groove 6.The centre of above-mentioned oblique groove 7,7 ＇ and interior arc groove 6 forms the lightning shape for one section, like this can more rational refinement pattern block, not only can improve the wet-sliding resistant performance of tire, and can significantly reduce compression to air, thereby greatly reduce the high frequency noise of tire, provide quiet comfortable driving to experience to the driver, gripping pattern rill 8 has not only improved the wet-sliding resistant performance of tire, and optimized the rigidity of colored piece, favourable and reduction tire path is made an uproar, and has strengthened the riding stability and the deceleration and stopping performance of tire.

As shown in Figure 1, tire shoulder pattern rib 5 is provided with from the outward extending long sharp knife shape groove 9 of inboard straight flange, the tire shoulder pattern rib is divided into some little piecemeals, each little piecemeal is provided with outward extending internally short sharp knife shape groove 10, its shape is similar with long sharp knife shape groove 9, the width of curve groove 3 is 6～8mm with the width of long sharp knife shape groove 9, the radius of the radius on arc limit, whale dorsal fin shape pattern block both sides and laemodipodiform decorative pattern rib both sides concave shaped is 140～160mm, the arc limit of whale dorsal fin shape pattern block both sides is a translation relation, the concave shaped of its long arc limit and laemodipodiform decorative pattern rib is an offset relationship, curve groove 3 between the whale dorsal fin shape pattern block is 22～28mm with the aperture pitch of adjacent long sharp knife shape groove 9, and the actual value of present embodiment is 25mm.The sharp knife shape groove of above-mentioned different in width, not only guaranteed the draining rapidly and effectively of tire shoulder position, have excellent wet and slippery road surface maneuvering performance and wet-sliding resistant performance, and refinement tire shoulder position pattern block, optimized tire shoulder position rigidity rightly, the tire comfort property is made an uproar, improved on the reduction road all bigger help.

As shown in Figure 1, the little piecemeal of each of tire shoulder pattern rib is provided with the anti-skidding fine groove 11 that three roads extend inwards from inboard straight flange, and its radian is all consistent with long sharp knife shape groove 9, and wherein the end of anti-skidding fine groove is communicated with short sharp knife shape groove 10 together.These thin tire sipes by geometric configuration and arranging density optimization can further reduce the tyre surface road and make an uproar, improve drainage performance by puncturing moisture film, reduce pattern block rigidity and improve the tire traveling comfort, can strengthen slush tractive force on the ground, improve the driving stability of doing on the wet road surface, prevent irregular wear, these thin tire sipes by geometric configuration and arranging density optimization can strengthen slush tractive force on the ground simultaneously, improve the driving stability of doing on the wet road surface, prevent irregular wear.

Usually directly cross in the journey at vehicle, the ground connection impression of tire protector is oval to keep enough earth-grasping forces.But work as Ackermann steer angle, the ground connection impression of tyre surface can change, as accompanying drawing 2 are analog demenstration figure of the ground connection impression variation of right front tire tread, straight arrows is represented working direction, curved arrow is represented turn direction, obviously, this tire can keep enough tyre surface ground contact area guaranteeing good manoeuvring safety performance and earth-grasping force in the turning process of fierceness, thereby excellent handling is provided.

The utility model is not limited to above-mentioned preferred forms, and anyone can draw other various forms of products under enlightenment of the present invention.Though but on its shape or structure, do any variation, every identical with the utility model or akin technical scheme is all within its protection domain.
