Abstract
The utility model relates to a pneumatic tire for a motorbike outdoor competition. A tire face comprises a tire crown area, a middle area and a tire shoulder area. The width of the tire crown area, the width of the middle area and the width of tire shoulder area are identical. The ratio of a tread pattern block is 30% to 45%. The tire crown area is provided with a square tire crown pattern block. The middle area is provided with a rectangular middle pattern block. The tire shoulder area is provided with a rectangular tire shoulder pattern block. The tire shoulder pattern block, the tire crown pattern block and the middle pattern block are arranged in intervals. The pattern blocks of each area are arranged in parallel along the circumference direction. Straight line narrow grooves perpendicular to each other are formed in a surface of the tire crown pattern block. Oblique line narrow grooves parallel to each other are formed in a surface of the middle pattern block. The height of the tire shoulder pattern block is higher than that of the tire crown pattern block and that of the middle pattern block. Therefore ground contact areas of the pattern blocks are enlarged and the pattern blocks are prevented from falling down or cracking. A tire has large adsorption and ground grabbing capacity when climbing and jumping in outdoor road condition, good driving force is expressed and meanwhile tire shoulders are capable of bearing large impact force in jump.
Description
Technical field
The utility model is about a kind of Pneumatic tire for motorcycle, refer to especially a kind ofly guarantee tire in the climbing of the open-air road conditions such as rock or timber and have larger absorption when jumping to grab the ground ability, bring into play better propulsive effort, tire shoulder can bear the outdoor sports air-inflation tyre of motor bike of larger impact capacity when jumping simultaneously.
Background technology
The in the past outdoor sports of motor bike generally adopt the pattern block of rule to form with the air tread decorative pattern, for guaranteeing its propulsive effort and casting on uneven road surface, each pattern block arranged spaced, the sparse setting of pattern block, the whole land of decorative pattern is lower than arranging, the height that the pattern block operated by rotary motion is identical, the outdoor sports of this kind motor bike with air-inflation tyre in the open air road conditions (mainly take jungle as main, comprise chunk of wood, large rock, wet and slippery stone, tree root, when the roughness pavements such as step) going up climbing and jump, pattern block is vulnerable to the power from all directions, pattern block distortion resistivity is not good, fall easily piece or burst apart, the tire tread land is lower because this kind arranged in addition, the pattern block ground contact area is little, it is not good to control stability, can't bring into play when being the climbing of rock or timber road conditions and jump in the open air than large traction performance and absorption and grab the ground ability, and tire pattern block on tire shoulder when jumping also can't bear larger impact capacity simultaneously.Based on above problem, this case just produces thus.
The utility model content
The purpose of this utility model is to provide a kind of motor bike outdoor sports air-inflation tyre, can guarantee that tire has larger absorption and grabs the ground ability when the open-air road conditions climbing such as rock or timber and jump, bring into play better propulsive effort, tire shoulder can bear larger impact capacity when jumping simultaneously.
For achieving the above object, solution of the present utility model is:
The outdoor sports air-inflation tyre of a kind of motor bike, its tyre surface comprises the crown region at center, the shoulder zone of tyre surface both sides and the zone line between crown region and shoulder zone, wherein: crown region is all identical with the width of two zone lines and two shoulder zone, and the whole land of tread block ratio is 30% ~ 45%; Wherein crown region disposes foursquare crown pattern block, pattern block in the middle of the zone line configuration is rectangular-shaped, and shoulder zone disposes rectangular-shaped pattern block on tire shoulder; And pattern block on tire shoulder and crown pattern block and middle pattern block are arranged spaced, and each regional pattern block circumferentially is arranged side by side; The orthogonal straight line fine groove of described crown pattern block surface configuration, and the oblique line fine groove that middle pattern block surface configuration is parallel to each other; The height of pattern block on tire shoulder is higher than the height of crown pattern block and middle pattern block.
Axial distance between each pattern block of described crown region, zone line, shoulder zone is 5% ~ 15% of tread width, and the circumferential distance between each pattern block of crown region, zone line, shoulder zone is 15% ~ 25% of a decorative pattern unit circumferential lengths.
The axial and circumferential number of described straight line fine groove is set to respectively 2 ~ 4, and the distance between each straight line fine groove is set to 2 ~ 8mm.
The number of described oblique line fine groove is set to 2 ~ 6, the oblique line of oblique line fine groove and axially between angle be set to 40 ° ~ 60 °, the distance between each oblique line fine groove is set to 2 ~ 8mm.
Described zone line adjacent in the middle of two the oblique fine groove on pattern block surfaces be vertically and be symmetrical arranged.
The width of described straight line fine groove and the degree of depth are 0.3mm ~ 2.0mm.
The width of described oblique line fine groove and the degree of depth are 0.3mm ~ 2.0mm.
The outside overall profile that each fine groove on crown pattern block and middle pattern block surface distributes in the described decorative pattern unit is ellipticity.
The scope of the diff-H of described pattern block on tire shoulder and crown pattern block and middle pattern block is 1.5mm ~ 5mm.
After adopting such scheme, because the utility model is by the outdoor sports of motor bike air tread pattern structure optimal design, be that tyre surface is divided into Three regions, the crown region pattern block adopts the square shape design, the orthogonal straight line fine groove design of pattern block surface configuration, zone line and shoulder zone pattern block all adopt rectangular-shaped pattern block design, the oblique line fine groove design that zone line pattern block surface configuration is parallel to each other, the outside overall profile that each fine groove on crown pattern block and middle pattern block surface distributes in a decorative pattern unit is ellipticity.The relative crown region of shoulder zone pattern block, zone line pattern block arranged spaced, the setting of pattern block on tire shoulder height are higher than crown region and zone line pattern block height.So arrange, can improve the ground contact area of pattern block, avoid pattern block to fall piece or burst apart, grab the ground ability when tire has larger absorption in the open-air road conditions climbing such as rock or timber and when jumping, bring into play better propulsive effort, tire shoulder can bear larger impact capacity when jumping simultaneously.
