Description
Technical field
The utility model relates to a kind of auto tyre structure, relates in particular to a kind of tread pattern structure of motor tire.
Background technology
The passenger car tire decorative pattern is numerous in the prior art, is divided into usually driving decorative pattern, guiding decorative pattern etc.Generally adopt cros-rib tread to combine to the design of tire tread pattern, the performances such as the design-calculated decorative pattern is wear-resisting except considering, adherence properties, drainage, also will consider the aesthetic property of tire, and require tire to have stable startup and deceleration and stopping performance with circumferential pattern.Studies show that under identical condition, 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 bigger than circumferential pattern, and the oil consumption of cros-rib tread is big, falls piece easily.So common design is that cros-rib tread is used in combination by groove with circumferential pattern.
The tread of tyre structure generally is divided into pattern block and groove, and pattern block is discrete tread element, and it can be arranged to along the circumferencial direction of tire or the structure of side direction; Groove is with the pattern block interval, and it provides functions such as draining preferably and reduction noise.Using pattern block in tyre surface still is that groove can be by the final use decision of tire.When the designing tyre tyre surface, tread designer need be used in combination pattern block and groove, so that optimize the tread of tyre performance.The combination that pattern block is different with groove can realize different purposes, reach different effects.
The utility model content
The utility model provides a kind of radial tire tread, can provide enough braking forces and good road-holding property for vehicle.
For achieving the above object, the utility model adopts following technical scheme: its radial tire tread, comprise center running lug, sidepiece pattern block, pattern block on tire shoulder, center running lug is the circumferential pattern piece, the regularly arranged successively from inside to outside sidepiece pattern block in its left and right sides, pattern block on tire shoulder, center running lug is positioned at the middle position of tyre surface, between center running lug and the sidepiece pattern block, between the adjacent both sides pattern block respectively at interval by arc groove; Pass through bevelled side direction groove between the two adjacent center running lugs at interval; Be communicated with by auxiliary groove between the two adjacent arc grooves; By vertical circular groove at interval, arc groove is communicated with vertical circular groove between sidepiece pattern block and the pattern block on tire shoulder.
Center running lug is the circumferential pattern piece, and is elegant in appearance, and adhesion value is good on dried wet road surface, can provide enough braking forces for vehicle.Side direction groove and arc groove can reduce concentrating of center running lug pressure in the tire running process, can also make the overstocked discharge in the tire running process, reduce noise.
One end of arc groove originates in the interval between center running lug and the sidepiece pattern block, and arc groove passes the interval between the adjacent both sides pattern block, and the other end terminates in vertical circular groove.The initiating terminal of the arc groove at center running lug and sidepiece pattern block interval is tending towards vertically, and the clearing end of the arc groove that is communicated with vertical circular groove is tending towards laterally, the initiating terminal of arc groove direction to clearing end by vertically to laterally seamlessly transitting; Arc groove initiating terminal is to the width employing gradually wide design from narrow to wide of clearing end.Arc groove runs through one from the tyre surface middle part to shoulder, and is natural and tripping, effectively increases drainage space between tire and the road surface, the self-cleaning that helps travelling on the rainy day muddy road surface.
Auxiliary groove comprises two ditches that the degree of depth is different.Sidepiece is equipped with the sidepiece groove on pattern blocks.The sidepiece groove has been guaranteed to do ground-surface handling and at the ground-surface crossing ability of not mating formation, and slot wedge is sharp, can directly destroy the ground-surface moisture film, makes the direct ground connection of rubber, has improved the wetland performance.The sidepiece pattern block is the big-pattern piece, guarantees when curved extremely excessively, and the stability of tread contour, thus keep controlling accurately.The sidepiece pattern block can reduce rolling resistance, fuel-economizing, and pattern block is soft, beautiful.
The outside of pattern block on tire shoulder is provided with tire shoulder big-pattern ditch.Side near vertical circular groove on the pattern block on tire shoulder is provided with little groove of tire shoulder and auxiliary groove.All be provided with steel disc on center running lug, sidepiece pattern block, the pattern block on tire shoulder.
Usually most of position, the crown of tire middle part rigidity is very high, but is the bracing ply end points just at the tire shoulder position, and rigidity is lower, and for preventing shoulder mill and eccentric wear, this tyre surface has adopted the method for designing that increases the shoulder pattern block.The clearing end of the arc groove on the pattern block on tire shoulder connects the tire shoulder cross groove.The width of tire shoulder cross groove is greater than the width of the arc groove on the pattern block on tire shoulder.Connect by the circumferential pattern ditch between the two adjacent tire shoulder cross grooves.Gradually the groove of wide structure alleviates air push the influence that is produced in the tread contour groove, helps reducing noise, brings comfortable quiet driving impression.Pattern block on tire shoulder is provided with transverse auxiliary decorative patterned groove and auxiliary tire sipe.
Vertically between the normal of the furrow bank of circular groove and tread angle is arranged, angle between the furrow bank of vertical circular groove of close pattern block on tire shoulder and the normal of tread is 14 °-18 °, and the angle between the furrow bank of vertical circular groove of close sidepiece pattern block and the normal of tread is 10 °-14 °.Between the furrow bank of arc groove and the normal of tread angle is arranged, angle is 8 °-12 °.Vertically the furrow bank angle of circular groove has improved the stability that tire is run at high speed.Its furrow bank plays an important role to guaranteeing the tyre surface ground connection shape and the road surface holding power of doing, wet behind the inflation of tire.
Arrange groove and pattern block optimization location, in conjunction with its width, angle and microgroove ratio, scientific allocation, guarantee each pattern block hardness equalization of tire, make its braking driving stiffness and cornering stiffness rational Match, improve the stability that tire runs at high speed and turn to tracing ability, make take quite comfortable, also relatively quieter comparatively speaking.
This tread of tyre adopts dual purpose tread pattern, have enough braking forces and good maneuvering performance, and good looking appearance is generous.
