Abstract
The utility model discloses a winter tire of a truck and a passenger car, comprising a tire body, wherein the tire body is provided with a tread annular fringe block and the tread annular fringe block is provided with a bulge; the tread annular fringe block comprises a first fine decorative pattern, a middle fine decorative pattern and a second fine decorative pattern, which are in an integral structure; an included angle alpha between the first fine decorative pattern and the middle fine decorative pattern is 120-140 degrees; and an included angle beta between the second fine decorative pattern and the middle fine decorative pattern is 120-140 degrees. According to the winter tire, the tread annular fringe block is provided with the bulge, and the tread annular fringe block comprises the first fine decorative pattern, the middle fine decorative pattern and the second fine decorative pattern, which are in the integral structure; and the tread annular fringe block is in a double-bent structure, so that the structure enables an occluding force of a vehicle tire on a road surface to be greater and the vertical rigidity of a driving face of the vehicle tire is increased; and therefore, the winter tire is good for working on the road surface in winter.
Description
Technical field
The utility model relates to a kind of passenger tyre, is specifically related to a kind of stable tire of operability when on the face of main line, going.
Background technology
Tire used in winter is meant a kind of special tyre that snowfield and common main line face in the winter time use, and requires tire can guarantee can possess the good road-holding property that on the face of main line, goes again in snowfield ground-surface brake safety.Early stage Tire used in winter adopts the edge pin structure, and like patent CN200920053014.4, this structure can effectively provide the snowfield holding power, but tyre surface is attend institute's metal inlaying nail the main line face is had than macrolesion.The later stage Tire used in winter begins to adopt change decorative pattern block structured mode that the snowfield holding power is provided; Like patent CN200810183899.X and patent CN200410087180.8 etc.; Increase tire protector and ground-surface friction force through increasing two-dimentional serration cutter groove structure; But this structure only has more intense locking stiffness structure at the tread horizontal direction; And the pattern block that on the direction perpendicular to tread, is cut does not exist engaging structure rigidity less, thereby has influenced the run at high speed road-holding property of tire on the face of main line.
The utility model content
The technical matters that the utility model will solve is existing Tire used in winter, and the tread bar piece does not have engaging structure on perpendicular to the direction of tread, rigidity is little; Provide a kind of winter the card passenger tyre; Horizontal and vertical rigidity of tread surface can be provided, and pattern block cutter groove is open freely on the axial direction of assurance tire rolling.
The technical scheme of the utility model realizes in the following manner: a kind of winter the card passenger tyre; Comprise carcass; Carcass is provided with tyre surface ring grain piece, and tyre surface ring grain piece is provided with convexity, and said tread block comprises the first thin decorative pattern that is integral the formula structure, middle thin decorative pattern and the second thin decorative pattern; Angle between the first thin decorative pattern and the middle thin decorative pattern is 120 ~ 140 °, and the angle β between the second thin decorative pattern and the middle thin decorative pattern is 120 ~ 140 °.
Said convexity is a hemispherical projections.
The said first thin decorative pattern is parallel with the second thin decorative pattern.
Angle between first steel disc and the middle steel disc is 100 °, and the angle β between the middle steel disc and second steel disc is 100 °.
Said tread block is provided with reinforced rib.
The utility model on tread block, be provided with convexity; And tread block comprises the first thin decorative pattern that is integral the formula structure, middle thin decorative pattern and the second thin decorative pattern; Tread block presents the hyperbolic folded structure; This structure makes that the snap-in force of vehicle tyre road pavement is bigger, can increase vertical rigidity of vehicle tyre tread, helps tire road surface operation in the winter time.Show through the finite element analysis checking; The single pattern block load 700kg of the utility model; Tread and ground-surface laterally/vertically relative displacement is under the 0.05m condition, the pattern block that adopts the utility model structure all improves more than 50% to rigidity than the pattern block of General Two-Dimensional steel disc structure in length and breadth.And through the card of entrucking road test on the spot, the tire road-holding property is significantly improved.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is an A-A generalized section among Fig. 1.
The specific embodiment
Shown in accompanying drawing, a kind of winter, the card passenger tyre comprised carcass 1; Carcass 1 is provided with tyre surface ring grain piece 2; Tyre surface ring grain piece 2 is provided with convexity 3, and said tread block 2 comprises the first thin decorative pattern 2-1 that is integral the formula structure, middle thin decorative pattern 2-2 and the second thin decorative pattern 2-3, and the angle between the first thin decorative pattern 2-1 and the middle thin decorative pattern 2-2 is 120 ~ 140 °; Angle between the second thin decorative pattern 2-3 and the middle thin decorative pattern 2-2 is 120 ~ 140 °, such as: 120,125,130,135 or 140 °.
The structure of the tread block of the utility model can make the vehicle tyre road pavement that bigger snap-in force is arranged; Resulting tire has vertically the stability with lateral stiffness when the main line face goes, can guarantee that the opening of pattern block cutter groove freely on the axial direction of tire rolling.
In the utility model, said protruding 2 is hemispherical projections preferably.
In the utility model preferred version, the said first thin decorative pattern 2-1 is parallel with the second thin decorative pattern 2-3.
As the further improvement of the utility model, said tyre surface ring grain piece is provided with reinforced rib 4, is provided with after the reinforced rib, can increase the intensity of pattern block.
In the utility model; The module of pattern block sulfidization molding is corresponding with the tread contour block structure; Module be provided with protruding corresponding groove, with the cooresponding gap of reinforced rib, like this, after the tyre vulcanization moulding; Remove module, just on carcass, formed protruding and with the cooresponding reinforced rib in gap position.
