Abstract
The invention discloses a directional steel wire belt type pneumatic tire structure. A novel belt structure design is adopted; belt steel wires are arranged on the outmost sides of a left tire shoulder and a right tire shoulder and are symmetric about the central surface of a tire crown. The directional steel wire belt type pneumatic tire structure is suitable for pneumatic tires adopting steel wire belts, which include car tires, truck and passenger car tires, engineering machinery tires and the like. The belt structure comprises at least two working layers, at least one protection layer and at least one transition layer.
Description
Technical field
The present invention relates to tire production technical field.
Background technology
The steel belt air-inflation tyre of ordinary construction, normally the widest one deck work bracing ply lateral symmetry occupy wheel crown line of centers both sides, causes two tire shoulder outermost belt edges steel wire directions consistent.In tire rolling process, propulsive effort is reached wheel rim by engine, and wheel rim reaches tyre bead, tyre bead by propulsive effort and further propulsive effort reached to sidewall, tire shoulder, and propulsive effort is reached bracing ply, tyre surface by tire shoulder, and final propulsive effort reaches ground, and tire rolls forward.Propulsive effort is in the time reaching crown part from tire shoulder portion, and tire shoulder both sides stressing conditions changes, and a side bracing ply steel cord orientation is consistent with the direction of transfer of power, and opposite side is contrary.This side steel wire that steel cord orientation is contrary with the direction of transfer of power and the shearing force of rubber strengthen, and easily produce and damage, and cause tyre failure.
Summary of the invention
The object of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of above belt structure because of the stressed asymmetric damaged tyres causing in tire shoulder both sides that is intended to solve is provided, improve tire belt endurance quality and use security and stability.
The present invention is achieved by the following technical solutions:
A kind of oriented shaped steel wire bracing ply air-inflation tyre, comprise at least one pair of ring like steel wire coil assembly at tyre bead portion arrangement in parallel, at least one deck be wound around described bead coil carcass plies, comprise bracing ply fabricate block that steel cord strengthens, be placed in bracing ply fabricate block outside with dapple tread structure and extend to the sidewall of described tyre bead portion from described tyre surface.
Described bracing ply fabricate block is by least two-layer working lining bracing ply, and at least layer protective layer and maximum one deck cambic horizon form.
The orientation of two-layer working lining bracing ply steel cord is contrary.
Two-layer working lining bracing ply is provided with insulation rubber parts at end points place, both sides, to reduce the shearing stress at bracing ply end points place in operational process.
Two-layer working lining bracing ply cross central line c1, cross central line c2 do not overlap with wheel crown line of centers c, and cross central line c1, cross central line c2 occupy hat line of centers c both sides symmetrical dividing.
Two tire shoulder outermost bracing ply steel cord orientations are sentenced wheel crown longitudinal plane of symmetry symmetry at the left and right tire shoulder of tire.
Advantage of the present invention is:
Two-layer working lining bracing ply steel cord of the present invention orientation is contrary, and two-layer working lining bracing ply is provided with insulation rubber parts at end points place, both sides, to reduce the shearing stress at bracing ply end points place in operational process.Two working lining bracing ply cross central lines do not overlap with wheel crown line of centers, and symmetrical point occupy hat line of centers both sides, realize the orientation of bracing ply steel cord in the left and right tire shoulder outermost of tire with wheel crown longitudinal plane of symmetry symmetry.The force way that reaches two tire shoulder transmission of drive force in tire running process is consistent, guarantee two shoulder outermost bracing ply steel cord directions in propulsive effort transmittance process all with the direction of transfer of power always, avoid the tyre failure causing because of extra shearing force, reach the object that improves tire belt endurance quality and use security and stability.

Fig. 1 is tire transverse cross-sectional view of the present invention.
Fig. 2 is the present invention's two working lining bracing ply steel cord orientation schematic diagrams.
The specific embodiment
Embodiment: oriented shaped steel wire bracing ply air-inflation tyre as shown in Figure 1, 2, comprise at least one pair of ring like steel wire coil assembly 1 at tyre bead portion arrangement in parallel, at least one deck be wound around described bead coil carcass plies 2, comprise bracing ply fabricate block that steel cord strengthens, be placed in bracing ply fabricate block outside with dapple tread structure 4 and extend to the sidewall 3 of described tyre bead portion from described tyre surface.Described bracing ply fabricate block is by least two-layer working lining bracing ply 6,7, and at least layer protective layer 8 and maximum one deck cambic horizon 5 form.Two-layer working lining bracing ply 6,7 steel cord orientations are contrary.Two-layer working lining bracing ply 6,7 is provided with insulation rubber parts 9 at end points place, both sides, to reduce the shearing stress at bracing ply end points place in operational process.Two-layer working lining bracing ply 6,7 cross central line c1, cross central line c2 do not overlap with wheel crown line of centers c, and cross central line c1, cross central line c2 occupy hat line of centers c both sides symmetrical dividing.Two tire shoulder outermost bracing ply steel cord orientations are sentenced wheel crown longitudinal plane of symmetry symmetry at the left and right tire shoulder of tire.
