Description
Technical field
The present invention relates to a kind of tire tread pattern, particularly relate to a kind of decorative pattern of radial tire tread.
Background technology
Along with manned vehicle developing rapidly and universal, tire tread update speed of its assembling is constantly accelerated, and function segmentation, special feature are more outstanding, as by being divided into season such as all-year tire, summer tires, Tire used in winter, mud-and-snow tyre etc.Generally adopt cros-rib tread to combine with circumferential pattern to the design of tire tread pattern, the decorative pattern of design, except will considering wear-resisting, the performance such as adherence properties, drainage, also will be considered the aesthetic property of tire, and require that tire has stable startup and deceleration and stopping performance.Research shows, at identical conditions, the resistance to abrasion of cros-rib tread is better than the performance of circumferential pattern with braking ability; But the lateral sliding of cros-rib tread is larger than circumferential pattern, and the oil consumption of cros-rib tread is large, easily falls fast.So common design is combined by groove with circumferential pattern by cros-rib tread.
China's tire industry development is swift and violent, the design of tire is also more and more tending towards hommization, cause the classification of tire especially manned vehicle radial-ply tyre more careful, decorative pattern is as the important design factor of tire, progressively define difference in functionality type, as symmetrical decorative pattern (comprise undirected decorative pattern, singly to lead decorative pattern), non-symmetrical design etc. in snowfield tire decorative pattern, all season tyre, the speed step of current UHP (very-high performance radial-ply tyre) constantly raises.Tread design quality is the main factor affecting tire snowfield, ice face and face, main line maneuvering performance, but under several pavement conditions, weigh the difficult problem that tyre performance also becomes tire tread pattern design phase, winter Tire used in winter has good performance under ice road surface or snow pavement conditions, but is difficult to significantly improve the handling under ice road surface and snow pavement conditions simultaneously.
Summary of the invention
Technique effect of the present invention can overcome above-mentioned defect, provides a kind of radial tire tread pattern of passenger car, and it can provide larger braking force for vehicle, and has good road-holding property and road surface comformability, excellent combination property.
For achieving the above object, the present invention adopts following technical scheme: the centerline of its tyre surface is provided with central longitudinal to circular groove, tyre surface is divided into symmetrical two parts to circular groove by central longitudinal, central longitudinal is provided with center running lug, sidepiece pattern block, pattern block on tire shoulder from inside to outside respectively successively to the circular groove left and right sides, center running lug is longitudinal integral type pattern block, by main longitudinal circular groove interval between center running lug and sidepiece pattern block, by assistant longitudinal circular groove interval between sidepiece pattern block and pattern block on tire shoulder; By horizontal arc groove interval between adjacent both sides pattern block, one end of arc groove originates in main longitudinal circular groove, and the other end terminates in pattern block on tire shoulder, and arc groove is communicated with assistant longitudinal circular groove.
Center running lug adopts firm one pattern block, elegant in appearance, on dry wet road surface, adhesion value is good, can provide enough braking forces for vehicle, guarantee the stable of when running at high speed performance, center running lug adds the rideability on effective grounding area and ice road surface.The roomy central longitudinal in middle part is equipped with sidepiece, the open main longitudinal circular groove of shoulder, assistant longitudinal circular groove to circular groove, and the wetland face that can be formed after snow melt plays outstanding drainage performance.Main longitudinal circular groove, assistant longitudinal circular groove are roomy tortuous groove, drainage space between effective increase tire and road surface, be conducive to the spoil disposal draining that rainy day muddy road surface travels, because groove is wider, tire tread form after ensureing tyre inflating is played an important role, prevent tire irregular wear, the air overstock in traveling can be made simultaneously to discharge glibly, be conducive to reducing noise.Arc groove and circumferential pattern ditch can reduce concentrating of center running lug pressure in tire running process, can also make the overstocked discharge in tire running process, reduce noise.Arc decorative pattern cutter groove runs through one, natural and tripping, effectively increases drainage space between tire and road surface, is conducive to the self-cleaning that rainy day muddy road surface travels.The longitudinal groove of tyre surface headed by five longitudinal furrows, the pattern block in addition varied in size and being interspersed, can reduce the noise that pattern block sends when kiss the earth greatly.
Center running lug, sidepiece pattern block, pattern block on tire shoulder are all provided with the fine groove of inclination, fine groove undulate.
Fine groove adopts the configuration of depth groove interval, and namely adopt the configuration of dark, shallow, dark, SC, rigidity and softness are combined closely, and brings comprehensive ice face performance, uniform wear and ride comfort.
Arc groove is diminished to its degree of depth of clearing end gradually by initiating terminal.Tread rigidity from center running lug to pattern block on tire shoulder improves gradually, the ratio of the rigidity of center running lug, sidepiece pattern block, pattern block on tire shoulder is followed successively by 1: 1.4-1.6: 1.7-1.9, form rational ground contact pressure distribution: middle part pattern block flexible relative, be conducive to improving the ground pressure in the middle part of tire, increase the broken snow ability of tyre surface ground connection and craspedodrome performance; Sidepiece pattern block rigidity improves and improves the partially soft feature of the common tyre surface both sides flank of Tire used in winter; Tyre revolution to time ground pressure part transfer to shoulder, improve shoulder lug rigidity and be conducive to driving stability.
Central longitudinal is all provided with stepped projection to the bottom of trench of circular groove, main longitudinal circular groove, and projection has drag function, and occlusion snow face more deep when tire is travelled on the darker ground of accumulated snow, catches fresh, soft accumulated snow to improve tractive property.
The side of center running lug, sidepiece pattern block, pattern block on tire shoulder all arranges zig-zag longitudinal groove, can form snow post, improves tractive force.
Be provided with cutter groove outside pattern block on tire shoulder, between adjacent two arc grooves, be provided with two cutter grooves, be communicated with by Z-type groove between this two cuttves groove.Its cutter groove has the tiny trench design of the three-dimensional warp architecture of sharp edges: continuous intersection " Z " type of this groove on ground plane designs and have two kinds of functions in the similar engaged gears design of ground plane vertical surface: one is when running into contact in rough road, and the colored block that microgroove can be made automatically to close up formation one piece complete bears immense pressure; Two is when ice and snow road travels, sharp slot wedge can catch road surface again, increase earth-grasping force and tractive force, and this kind of design can increase the rigidity that tiny groove number significantly can not reduce again pattern block simultaneously, when starting at tire, brake or turn, the distortion of pattern block reduces, ground contact area increases, and tire friction force on ice road surface and face, main line improves.
Groove and pattern block optimum position arrange, and in conjunction with its width, angle and microgroove ratio, scientific allocation, ensures that each pattern block hardness of tire is impartial, make its braking driving stiffness and cornering stiffness Proper Match, improve the comformability of tire snowfield.
