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 passenger car 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 growing interest of and living environment healthy to self along with people, tire as the automobile important component part is faced with test, living with people, the exploitation of closely-related passenger vehicle tyre has embodied the design concept that people-oriented, summarizes and gets up to mainly contain two great development directions: energy saving and environment friendly tire and be the high-performance tire of high-speed secure performance brilliance.The latter is the research and development emphasis of each giant tyre company of the world always, and market competition is fierce unusually.The manufacturing of China's high-performance tire is at the early-stage, can not satisfy international market demand far away.
The utility model content
Technique effect of the present utility model can overcome above-mentioned defective, and a kind of passenger car tire tread contour is provided, and can provide enough braking forces and good road-holding property for vehicle.
For achieving the above object, the utility model adopts following technical scheme: it comprises center running lug, sidepiece pattern block, pattern block on tire shoulder, center running lug is positioned at the central authorities of tyre surface, 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 an integral type circumferential pattern piece, passes through vertical circular groove between center running lug and the sidepiece pattern block at interval; Pass through the assistant longitudinal groove between sidepiece pattern block and the pattern block on tire shoulder at interval; All pass through the side direction groove at interval between the adjacent sidepiece pattern block and between the adjacent pattern block on tire shoulder, the side direction groove is communicated with vertical circular groove, and the two ends of assistant longitudinal groove are communicated with two adjacent side direction grooves respectively.
Center running lug is vertical integral type pattern block, and is elegant in appearance, and adhesion value is good on dried wet road surface, can provide enough braking forces for vehicle, guarantees the craspedodrome stability simultaneously.The integral type pattern block has improved the rigid circumference of tyre surface, helps increasing the length of impression major axis, and powerful tractive force of sustainable transmission and braking force increase steering stability and sense of direction when travelling.Vertically circular groove and side direction 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, the reduction noise.Center running lug makes tire in the process of running at high speed, and pattern block is stable, and is not yielding, makes pattern block close proximity to ground equably, when condition of road surface changes, is enough to tackle strong wallop, guarantees the accurate of steering angle, has good high speed and controls stability.
The side direction groove is the L type, angle between side direction groove and the vertical circular groove is 20 °-30 °, seamlessly transit between side direction groove and the vertical circular groove, transitional slope shape edge can quicken ponding and be diverted in the side direction groove, the water that accumulates in the middle part in the tire straight-line travelling process can be discharged rapidly, reach the purpose of disperseing draining.Tiny groove by the assistant longitudinal groove between sidepiece pattern block and the pattern block on tire shoulder is cut apart, can give out the heat of savings when running at high speed fast, and the slot wedge that it is sharp, destroy moisture film rapidly, guarantee the tire effective grounding, guaranteed the safety of on the road surface of doing, wet, running at high speed.Between the furrow bank of main vertical circular groove and the normal of tread angle is arranged, angle is 10 °-14 °, and the furrow bank of groove 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.
The tire shoulder groove is set on the pattern block on tire shoulder, and the tire shoulder groove is communicated with the side direction groove.The tire shoulder groove is the L type.Be interval with auxiliary tire sipe ditch on the pattern block on tire shoulder, auxiliary tire sipe ditch is communicated with the bending place of L type side direction groove, and the structure of auxiliary tire sipe ditch provides tire splendid heat radiation, realizes high speed performance.Pattern block on tire shoulder 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.Wide and crash-resistant pattern block on tire shoulder provides lateral stability and sensitive steering reaction, even when highly difficult turning operation, and the tread elements shape that also can remain unchanged.The pattern block on tire shoulder of one design continuously improves the whole wear hardness of tire, obtains higher service life.The tire shoulder groove improves resonance frequency under the prerequisite of efficiently radiates heat, reduce noise.
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 and take advantage of seat quite soft, also relatively quieter comparatively speaking.
This tire decorative pattern unit design is mainly controlled safety performance and quiet, traveling comfort two broad aspect lifting tyre performance from the high speed of tire, at first consider how to allow tire run at high speed, carrying out abrupt maneuver or changing to make tire bear great force on the road surface, can both effectively guarantee ground contact area and the heat that gives out savings easily on the road surface of doing, wet, thereby reach the purpose of accuracy control.Than common passenger car tire decorative pattern, has excellent high stability; Wet road road-holding property, water dumping effect excellence; The peak noise ability of pattern block is effectively reduced, realize tire low noise, comfortable quiet.
This tread of tyre adopts dual purpose tread pattern, have enough braking forces and good maneuvering performance, and good looking appearance is generous.
