Description
Technical field
The utility model relates to a kind of motor tire, relates in particular to a kind of tread pattern structure of motor tire.
Background technology
The band tire decorative pattern is numerous in the prior art, is divided into usually driving decorative pattern, guiding decorative pattern and trailer decorative pattern.The design that tire tread pattern adopts cros-rib tread to combine with circumferential pattern can effectively improve tire to different ground-surface comformabilitys.Pattern Design is mainly considered performances such as resistance to abrasion, adherence properties, drainage, the noise that goes, braking ability, also will have attractive in appearance, generous characteristics in addition.Technical study shows that generally, the resistance to abrasion of cros-rib tread is better than the performance of circumferential pattern with braking ability; The lateral sliding of cros-rib tread is bigger than circumferential pattern, and the oil consumption of cros-rib tread is big, collapses easily and uses up piece.For guaranteeing the Combination property of tire, normally adopt cros-rib tread and circumferential pattern to be used.
The tread of tyre structure generally is divided into pattern block and groove, and pattern block is for continuously or independently block unit; Groove is with the pattern block interval, and it provides functions such as draining preferably and reduction noise.In tyre surface, to use pattern block still be groove by the final use decision of tire, need take into full account factors such as aerodynamics through test many times.When tread design, take into full account the factor such as use road conditions, load carrying ability size, moving velocity, climatic conditions of tire.
The utility model content
The technique effect of the utility model can overcome above-mentioned defective, and a kind of heavy-duty truck tyre tread decorative pattern is provided, and it can be for vehicle provides bigger braking force, and has good road-holding property and road surface comformability, excellent combination property.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: the heavy-duty truck tyre tread decorative pattern; The centerline of tyre surface is provided with central longitudinal to circular groove; Central longitudinal is provided with center running lug, sidepiece pattern block, pattern block on tire shoulder from inside to outside successively to the circular groove left and right sides; Through vertical circular groove I at interval, through vertical circular groove II at interval, between the adjacent center running lug of tyre surface circumferencial direction, be provided with cross groove I between sidepiece pattern block and the pattern block on tire shoulder between center running lug and the sidepiece pattern block; Between the adjacent sidepiece pattern block of tyre surface circumferencial direction, be provided with cross groove II; Between the adjacent pattern block on tire shoulder of tyre surface circumferencial direction, be provided with cross groove III, central longitudinal is communicated with cross groove I respectively to the both sides of circular groove, and vertically the both sides of circular groove I are communicated with cross groove I, cross groove II respectively; Vertically the both sides of circular groove II are communicated with cross groove II, cross groove III respectively, and vertically center running lug, sidepiece pattern block, the pattern block on tire shoulder of circular groove I both sides all are the point symmetry distribution and shift to install up and down.
Central longitudinal is along the circumferential direction linearly extended to circular groove, has reduced the rolling resistance of tire greatly.Groove is crisscross, and pattern block is divided into the independently block structure of polygon, and pattern block is point symmetry with respect to the tyre surface center and arranges along vertical, the oblique proper alignment of tyre surface.
Center running lug, sidepiece pattern block, pattern block on tire shoulder are all the block structure of polygon, its shape approximation, the pattern block shape is similar can guarantee to form laterally, circumferential pattern ditch marshalling, regular.Pattern block shifts to install up and down and can make pattern block stressed evenly, reduces rolling resistance and goes noise.The pattern block point symmetry is arranged and is made pattern block overall appearance, generous, orderly.
The side of center running lug, sidepiece pattern block, pattern block on tire shoulder all is provided with the broken line v notch v, and the broken line v notch v cooperates with vertical circular groove, forms shallow broken line shape.The broken line v notch v can make the circumferential pattern ditch form shallow broken line shape, and its shape both can reduce tire drag between straight line and common broken line, can improve handling again.
All be provided with Z type tire sipe on center running lug, sidepiece pattern block, the pattern block on tire shoulder, can guarantee in wet and slippery ground-surface goes to cut off moisture film, improve wet and slippery road surface handling, can play heat radiation, effect attractive in appearance again.
Central longitudinal is provided with reinforced rib I to the bottom of trench of circular groove.The length of reinforced rib I is the 30%-50% of center running lug length, and the height of reinforced rib I is the 30%-60% of central longitudinal to the circular groove total depth.The bottom of trench of cross groove III is provided with reinforced rib II, and the height of reinforced rib II is the 30%-60% of cross groove III total depth.The bottom of trench reinforced rib has increased the rigidity of center running lug and shoulder pattern block, can effectively avoid irregular wear.
Central longitudinal is vertical with tyre surface to the groove furrow bank; Vertically angle is all 6-20 ° between the furrow bank of circular groove I, vertical circular groove II, cross groove I, cross groove II, cross groove III and the tyre surface normal, thereby two sections cross grooves form the wide-angle broken line shapes.Central longitudinal adopts narrow ditch design to groove, and width is 4-8mm, according to the groove width; Bottom of trench adopts full radius to connect two decorative pattern furrow banks, and furrow bank becomes 0 ° (U type ditch) with the tyre surface normal, and cooperates the bottom of trench reinforced rib; Can suitably increase the center running lug rigidity, improve the pattern block resistance to abrasion.Other horizontal and vertical groove furrow bank becomes 6-20 ° of angle (V-type ditch) with the tyre surface normal, foreign matter such as stone sandwiches in can effectively preventing to go.
The degree of depth of all grooves is identical.Except that central longitudinal to groove adopts the design of narrow ditch; Other vertically, the width of cross groove, the degree of depth be all similar; The crisscross perforation of broken line type groove; Both can improve tire braking performance, handling, wet-sliding resistant performance, be beneficial to the smooth and easy discharge of air of overstocking in going again, greatly reduce generation of noise.
This tread of tyre adopts independent block-type tread, and groove is crisscross, have enough braking forces and good maneuvering performance, and good looking appearance is generous.
