Embodiment Construction

[0010] The tire carcass layer (2) and the belt layer (8) of the present invention all adopt aramid chemical fiber cord fabric, which increases the adhesion between the tire carcass layer (2), the belt layer (8) and rubber, and improves Tire service life.

[0011] The production molding process adopts a one-time molding method: in the accompanying drawing 1, the rubber material is used to make the capsule molding drum, and the setting is adjustable. Flat drum (uninflated) size is used; when forming the belt layer (8), sidewall rubber (6) and crown rubber (7), the capsule forming drum is used to fill in compressed air to achieve a certain shape and size before forming the belt layer (8), sidewall rubber (6), and tire crown rubber (7); the technical problem that aramid radial giant OTR tires cannot be molded at one time is solved. All parts of the tire, carcass layer (2), bead ring (3), apex (4), belt layer (8), sidewall rubber (6), and crown rubber (7) are all in the variable r...

Abstract

The invention relates to a forming method of huge engineering tyre of aramid fibre meridian, the belt and the tyre body layer of tyre all use the aramid fibre chemical fiber flat chafer fabric, capable of improving the adhesive force between the meridian huge engineering tyre body layer, the belt and the rubber, and reducing the tyre weight, energy conservation, improving useful life of the tyre, the manufacture forming process uses method of forming in one piece to simplify forming manufacture process and improve productivity effect.

Description

Technical field: [0001] The invention relates to a method for forming an aramid radial giant engineering tire. Background technique: [0002] Existing radial giant OTR tire adopts steel cord fabric or semi-steel wire and semi-chemical fiber cord fabric to make the carcass and belt ply of radial giant OTR tire during design. Because the problem of poor adhesion often occurs between the steel wire and the rubber, it affects the service life of the tire. Moreover, the density of steel cord fabric is higher than that of aramid fiber, and the weight of the product is larger. The manufacturing process of radial giant OTR tires usually adopts the secondary molding method, which is complex, requires a large investment in tooling equipment, and has low production efficiency. Invention content: [0003] In order to overcome the shortcomings of the existing radial giant OTR tires, the present invention adopts high-strength aramid chemical fiber cord fabrics and steel cord fabrics, ...
