Abstract
The utility model discloses a stone clamping prevention structure for a pneumatic tire tread. Two or more than two main grooves are distributed on the tire tread along the circumferential direction of a tire; strip-shaped decorative patterns are formed among the main grooves; a plurality of projections are arranged on the left wall and the right wall of the bottom of each main groove in a transversely extending manner; and the projections are evenly distributed in the main grooves at intervals. As the stone clamping prevention projections transversely extend from the bottoms of the left walls and the right walls of the main grooves and are evenly distributed in the main grooves at intervals, the formed projections are capable of effectively filling gaps of the main grooves, stones entering the main grooves of the tire tread are discharged more easily, and then the stones are prevented from being clamped in the main grooves and damaging groove walls. Simultaneously, the drainage performance of the main grooves can be effectively kept by the aid of the structure that the transversely arranged projections are evenly distributed at intervals.
Description
Technical field
The utility model relates to a kind of air-inflation tyre, is meant a kind of air tread anti-pinch stone structure especially.
Background technology
Air-inflation tyre all disposes circumferentially at its tread portion, groove radially, and each ground connection position that is partitioned into by groove has formed satisfies the pattern block that tyre performance and usage condition require.When tire when having relatively poor road surface such as stone row to relax, stone can enter in the groove of air tread, and tyre surface ground connection position meeting torsional deflection under being loaded, make stone be difficult for from groove, discharging, can enter bottom of trench gradually after then the stone of different sizes enters groove, damage bottom of trench and may damage the bracing ply of tire causes fault, influences the service life of tire.
Therefore make and airtyred anti-pinch lithopedion face structure occurred, it mainly is to be provided with projection in the tap drain bottom of the circumferential groove of tire protector, when stone enters groove, furrow bank prevents that stone from embedding in the groove, and when stone is arranged in groove, the projection deformation in compression of bottom of trench can be given antagonistic force of stone, makes the easier discharge groove of stone.
But central authorities are provided with the structure of projection at the bottom of this tap drain, though can fully prevent to produce the function of horsestone, can but can be significantly impaired to the drainage of tap drain; In addition, because stone is when entering during groove extruding projection, the connecting portion that the distortion of projection appears at projection and bottom of trench easily cracks, and then influences the service life of tire.So the anti-pinch stone structure of tire is still waiting to improve, this case just produces thus.
The utility model content
The purpose of this utility model is to provide a kind of air tread anti-pinch stone structure, and its order enters the easier discharge of stone in the groove, and guarantees the drainage performance of tire.
Another purpose of the present utility model provides a kind of air-inflation tyre tire anti-pinch stone structure, and its order enters the easier discharge of stone in the groove, and ensures the service life of tire.
For achieving the above object, solution of the present utility model is:
A kind of air tread anti-pinch stone structure, this tire protector circumferentially is distributed with main line more than two and two along tire, form the bar shaped decorative pattern between each main line, wherein: horizontal expansion has several projections on the left and right sides furrow bank of each main line bottom, and each projection is the interval and is distributed in the main line uniformly.
Described each projection is provided with identical height.
Each projection on the furrow bank of the described left and right sides is and staggers mutually and be provided with.
Described main line is the corrugated setting of bending, and each projection is provided in a side of the bending place of main line projected side wall, and the place, inflection point forms the disconnection groove.
After adopting such scheme, since the utility model is an anti-horsestone projection in the tire protector main line be set to by about two furrow bank bottom transverse extend and be uniformly at intervals, so the projection that forms can effectively be replenished the tap drain gap, make the easier discharge of the stone that enters in the tire protector main line, prevent that stone is clipped in damage and furrow bank in the tap drain; Simultaneously, the projection of this horizontally set structure uniformly at intervals can effectively keep the drainage performance of main line again.
In addition, projection links to each other with tap drain and at tap drain turning fluting, then tire is being subjected under the external force situation, and jut is difficult for torsional deflection, guarantees the lithagogue effect of projection and prevents the projection fracture, thereby ensure the service life of tire.
Description of drawings
Fig. 1 is the partial schematic diagram that the utility model tire protector launches;
Fig. 2 is the utility model tire partial schematic sectional view radially;
Fig. 3 is the partial enlarged drawing of Fig. 2.
The specific embodiment
As shown in Figure 1, 2, 3, the utility model has disclosed a kind of air tread anti-pinch stone structure, be the main line 1 that circumferentially is distributed with more than two and two on this tire protector, be set to four main lines 1 among this embodiment, just forming bar shaped decorative pattern 2 between each main line 1; Key of the present utility model is: horizontal expansion has several projections 3 on the two bottom sides furrow bank of each main line 1, and each projection 3 is the interval and is distributed in uniformly in the main line 1.
Because the projection 3 of horizontally set, can effectively replenish the gap of main line 1, enter the function that the stone of main line 1 is ejected main lines 1 and plays anti-horsestone by this projection 3 in can making tire be expert at relaxing, in addition, one side and the bottom of each projection 3 all link together with tire body, thereby the effect of its anti-horsestone can be better; Simultaneously horizontally set and the drainage performance that is 3 pairs of main lines 1 of projection spaced apart can not cause damage, thereby have guaranteed the drainage performance of main line 1.
Each projection 3 can have the setting of equal height, also can adopt being crisscross arranged of differing heights; Projection 3 on the two lateral walls can be interlaced and be provided with, and so makes the drainage performance of main line 1 further be guaranteed.
Cooperate shown in Figure 1ly, the main line 1 on the tyre surface can be the corrugated setting of bending, and then each projection 3 just is arranged on the bending place of main line 1 projected side wall, and forms at the place, inflection point and to disconnect groove 31; So setting can be subjected under the situation of external force, and projection 3 is difficult for torsional deflection, guarantees the lithagogue effect of projection 3, and prevents projection 3 fractures, thereby ensures the service life of tire.
