Its technical scheme is: a kind of fibrage strengthens the tyre surface radial-ply tyre; Comprise the tyre surface of circumferential hoop around the wheel crown part; Be symmetricly set on the sidewall of tire both sides; Bracing ply, tyre bead and prolonging are walked around tyre bead and are formed a pair of anti-package partial sum laterally from inboard anti-package and be positioned at the inboard tire carcass of tyre bead, said tyre surface comprise bottom sizing material layer, top sizing material overplate and be arranged on said bottom sizing material layer and top sizing material overplate between fiber-reinforced layer.
Said fiber-reinforced layer is the rubberized cord that fiber cord or fiber canvas form after rolling.
Said fiber increases in the layer and forms angle between the fiber orientation and tire tread pattern tap drain, and angle is between 10-90 °.
Fibre strength is more than the 200N/ root in the said fiber-reinforced layer, calendering density in 30/10cm～100 piece/10cm, fibre diameter is at 0.3～2.0mm.
Said bottom sizing material layer is a kind of sizing material or the compound composition of multiple sizing material layering.
Said top sizing material cover thickness is at 2～4mm.
The utility model be set to bottom sizing material layer, top sizing material overplate through tyre surface and be arranged on said bottom sizing material layer and top sizing material overplate between fiber-reinforced layer; Can improve the tread contour rigidity, reduce stress deformation in the tire running process, improve the anti-puncture performance and the shock resistance of tire; Effectively reduce groove base portion glue thickness; Alleviate tire weight, reduced tire drag, prolonged the service life of tire.

The specific embodiment
Embodiment one:
As depicted in figs. 1 and 2; A kind of fibrage strengthens the tyre surface radial-ply tyre; Comprise the tyre surface of circumferential hoop, be symmetricly set on the sidewall of tire both sides, bracing ply 4 around the wheel crown part; Tyre bead 9 and prolonging is walked around tyre bead 9 and is formed a pair of anti-package partial sum laterally from inboard anti-package and be positioned at the inboard tire carcass 7 of tyre bead 9, and said tyre surface comprises bottom sizing material layer 1, top sizing material overplate 3 and is arranged on the fiber-reinforced layer 2 between said bottom sizing material layer 1 and the top sizing material overplate 3.
Said fiber-reinforced layer 2 is the rubberized cord that fiber cord or fiber canvas form after rolling.Can play a protective role to tyre surface through this structure, prolong the service life of tire greatly.
Form angle between fiber orientation and the tire tread pattern tap drain in the said fiber-reinforced layer 2, angle is between 10-90 °.
Fibre strength is more than the 200N/ root in the said fiber-reinforced layer 2, calendering density in 30/10cm～100 piece/10cm, fibre diameter is at 0.3～2.0mm.
Said bottom sizing material layer 1 is a kind of sizing material or the compound composition of multiple sizing material layering.
Said top sizing material 3 cover thicknesss are at 2～4mm.
During making; After wirecord fabric in carcass 7, bracing ply 4, tyre bead 9 combinations is rolled by the wirecord fabric flattening mill; Directly cut out machine or the severing of wirecord fabric bias cutter according to the tire design construction parameter by wirecord fabric, the sizing material half-blank in tyre surface bottom sizing material layer 1, pad glue 5, sidewall 8, inside liner 6 and tyre bead 9 combinations is extruded by extruder.More than each parts make up on make-up machine according to molding construction technology.
After tyre surface fiber-reinforced layer 2, tyre surface top sizing material overplate 3 roll into cord and film by flattening mill respectively, according to detail desige by severing.
Tyre surface fiber-reinforced layer 2, tyre surface top sizing material overplate 3 are applied on the tyre surface bottom sizing material layer 1 in order, and strengthen the tyre surface radial-ply tyre by promptly becoming fibrage after the vulcanizer sulfuration.
