Abstract

The utility model relates to a tire bead of an all-steel radial truck tire. The tire bead comprises a steel ring of the tire bead, wherein tire bead wear-resistant rubber coats the bottom of the steel ring of the tire bead, the steel ring of the tire bead is provided with an outer steel wire ring which clamps the anti-bag free end point of the tire steel wire, the outer steel wire ring is provided with triangular rubber, and a tire body steel wire curtain and a tire body inner seal layer are sequentially arranged outside the triangular rubber from inside to outside. The tire bead provided by the utility model overcomes the design deficiency of the anti-bag free end point of the tire steel wire, a tire bead steel wire-wrapped reinforced layer is saved, the volume of the triangular rubber is greatly reduced, and the design cost is lowered.

Description

All steel load radial tyre circle

Technical field

The utility model relates to a kind of novel all steel load radial tyre circle.

Background technology

The main Quality of all steel load radial tire is that tyre bead rim of the mouth is split, its reason is that tyre bead place has a carcass wirecord fabric anti-package layer, the end points free point of cord anti-package layer, free point is Design of Tire Structure defect, cord anti-package free point splits and causes damaged tyres to account for 90% of whole damaged tyres, in order to overcome this design defect, tire design worker has increased layer of steel wire infantees enhancement Layer at tyre bead portion, although splitting to some extent, rim of the mouth takes a turn for the better, but free end breach still accounts for 70% of whole damaged tyres, and meanwhile increase the inside and outside free end points of steel bead wire infantees enhancement Layer.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned defect, provides one can reduce significantly triangle rubber volume, thereby reduces all steel load radial tyre circle of design cost.

To achieve these goals, the all steel load radial tyre circle of the utility model design, comprise bead bundle, the bottom outside of described bead bundle is coated with the wear-resisting glue of tyre bead, on described bead bundle, be provided with the cover wire circle of clamping the free end points of carcass steel wire anti-package, on described cover wire circle, be provided with triangle rubber, the outside of described triangle rubber is disposed with carcass wirecord fabric and carcass inner seal layer from inside to outside.

In technique scheme, the wear-resisting glue of tyre bead is connected with sidewall rubber.

The utility model has increased a special-shaped cover wire circle on bead bundle, clamp the free end points of carcass steel wire anti-package, solve the design defect of the free end points of steel bead wire cord anti-package, save steel bead wire infantees enhancement Layer, can reduce significantly triangle rubber volume, thereby reduce design cost.

Brief description of the drawings

Fig. 1 is integral structure schematic diagram of the present utility model;

In figure: 1-bead bundle; The wear-resisting glue of 2-tyre bead; 3-cover wire circle; 4-triangle rubber; 5-carcass wirecord fabric; 6-carcass inner seal layer.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:

All steel load radial tyre circle as shown in Figure 1, comprise bead bundle 1, the bottom outside of bead bundle 1 is coated with the wear-resisting glue 2 of tyre bead, on bead bundle 1, be provided with the cover wire circle 3 of clamping the free end points of carcass steel wire anti-package, on cover wire circle 3, be provided with triangle rubber 4, the outside of triangle rubber 4 is disposed with carcass wirecord fabric 5 and carcass inner seal layer 6 from inside to outside.The wear-resisting glue 2 of tyre bead is connected with sidewall rubber 7.

The utility model has increased a deformed steel wire ring on bead bundle, clamp the free end points of carcass steel wire anti-package, solve the design defect of the free end points of steel bead wire cord anti-package, save steel bead wire infantees enhancement Layer, can reduce significantly triangle rubber volume, thereby reduce design cost.

The content not being described in detail in this specification sheets belongs to the known prior art of professional and technical personnel in the field.
