Abstract
The utility model discloses a high-adhesiveness agricultural tire bead, which comprises an apex rubber core, a steel wire ring and a steel wire wrapping cloth; the steel wire wrapping cloth is used for wrapping the triangular rubber core and the steel wire ring; the triangular rubber core and the steel wire ring are distributed and arranged up and down; the wire diameter of the steel wire wrapping cloth is 0.55mm, the density of the cord threads is 60 threads/cm, and the thickness of the cord threads is 0.77-0.80 mm; the diameter of the steel wire ring is more than or equal to 400mm, and the steel wire wrapping cloth wraps the triangular rubber core at the height 1/2. Or the diameter of the steel wire ring is less than 400mm, and the steel wire wrapping cloth is wrapped to the position of the height 2/3 of the triangular rubber core. The utility model discloses use low density steel wire infantees and downside semi-enclosed structure steel wire winding, it is more firm not only to make triangle gum and steel wire cooperation in the production process, when still making the triangle gum vulcanize, under the effect of internal pressure, remove the shape that changes self along the route of balanced profile, the requirement of better adaptation balanced profile.
Description
Technical Field
The utility model relates to a tire design especially relates to a high adhesion agricultural tire bead with manufacturing, belongs to the rubber processing field.
Background
The bead ring plays a major role in the tire in firmly fixing the tire to the rim. The stress generated by the internal pressure and the centrifugal force generated at high speed are overcome to ensure the normal running of the automobile. The steel wire ring is usually composed of steel wires, triangular glue, steel ring wrapping cloth and the like. The steel wire is used for guaranteeing the strength of the tire bead, the bead filler plays a role in filling the bead ring, the profile of the tire bead is enabled to be uniform in transition, and the bead ring wrapping cloth mainly plays a role in fixing the steel wire and the bead filler, so that the forming process operation is facilitated. Because the number of plies of the cord fabric of the agricultural tire is small, the height of the apex is generally increased for enhancing the rigidity of the tire bead, and the apex and the steel wire are completely sealed by adopting a full-surrounding ring-wrapping mode in a flexing area. If the apex is not aligned when the steel wire wrapping cloth is wrapped, gaps exist in the steel wire ring, and the steel wire ring and the wrapping cloth can be separated due to the fact that gas is heated and expanded in the vulcanization process. In addition, the mobility is high during deflection molding, so that the deformation of the triangular rubber strip influences the design outline of the tire bead part, and the uniform transition of the bead opening thickness is also influenced, thereby causing stress concentration at the part and causing serious quality problems such as bead bulging, fracture and the like. Therefore, the existing method not only has more steel wire wrapping cloth consumption and high material cost, but also causes the problems of excessive stress concentration of the material at the rim part, heat generation increase, burst of the rim of the tire and the like.
Disclosure of Invention
In order to overcome the not enough of above-mentioned prior art, the utility model discloses an use low density steel wire infantees to adopt the half encirclement of downside to enclose the circle mode, solve above-mentioned problem, make tire bead material distribute more rationally, improve tire life.
The utility model is realized by the following technical proposal, the high-adhesiveness agricultural tire bead comprises an apex rubber core, a steel wire ring and a steel wire wrapping cloth;
the steel wire wrapping cloth is used for wrapping the triangular rubber core and the steel wire ring; the triangular rubber core and the steel wire ring are distributed and arranged up and down;
the wire diameter of the steel wire wrapping cloth is 0.55mm, the density of the cord threads is 60 threads/cm, and the thickness of the cord threads is 0.77-0.80 mm;
the diameter of the steel wire ring is more than or equal to 400mm, and the steel wire wrapping cloth wraps the triangular rubber core at the height 1/2.
A high-adhesiveness agricultural tire bead comprises an apex, a bead ring and a flipper;
the steel wire wrapping cloth is used for wrapping the triangular rubber core and the steel wire ring; the triangular rubber core and the steel wire ring are distributed and arranged up and down;
the wire diameter of the steel wire wrapping cloth is 0.55mm, the density of the cord threads is 60 threads/cm, and the thickness of the cord threads is 0.77-0.80 mm;
the diameter of the steel wire ring is smaller than 400mm, and the steel wire wrapping cloth wraps the triangular rubber core to the height 2/3.
The utility model has the advantages that
The utility model discloses use low density steel wire infantees and downside semi-enclosed structure steel wire winding, it is more firm not only to make triangle gum and steel wire cooperation in the production process, when still making the triangle gum vulcanize, under the effect of internal pressure, remove the shape that changes self along the route of balanced profile, the requirement of better adaptation balanced profile. The bead filler flows upwards uniformly without being bound by the steel wire wrapping cloth above the bead filler, is natural in shape and is combined with the cord fabric to form better transition, so that the bead filler is slender, the highest point of the bead filler reaches above a waterproof line, the H1 area of the lower tire side is reinforced, and the overall combination performance and the dynamic fatigue performance of various materials at the tire bead part are improved. The service life of the tire is prolonged, the using amount of the steel wire wrapping cloth is reduced, the material cost is reduced, and the market competitiveness of the product is improved.
