Abstract
The utility model discloses a high strength 21-ply steel wire with an externally winding steel wire, which is composed of 22 steel wires, wherein the inner layer is 2 steel wires, the middle layer is a circle layer made of 7 steel wires and the outer layer is a circle made of 12 steel wires which is in the state of an approximate ellipse cross section. The outside of the outer layer is provided with an externally winding steel wire; the inner layer is in the state of S twist of which the pitch of twist is 12.0MM; the middle layer is in the state of Z twist of which the pitch of twist is 18MM; the outer layer is in the state of S twist of which the pitch of twist is 5.0MM. The utility model has the advantages of antifatigue, good corrosion resisting properties and small weight proportion occupation of a tyre.
Description
Technical field
The utility model relates to a kind of as the intensive shaped steel cord of using in the pneumatic tire.
Background technology
Almost very close to each other between the steel wire of existing steel cord, make rubber be difficult to penetrate in the steel cord, cause that the bonding force of steel cord and rubber descends.And, have the space because rubber can not fully be penetrated in the monofilament of steel cord, and water conservancy diversion moisture is played in these spaces or the salt moisture penetrates in the steel cord, and when tire during by deflection repeatedly, the steel cord will accelerated corrosion, the service life of reducing tire.
Summary of the invention
The utility model provides a kind of endurance, corrosion resistance and good, accounts for tire weight than outer 20 one high strength steel cords around steel wire of little band.
The utility model is a kind of with outer 20 one high strength steel cords around steel wire, it is made up of 22 steel wires, and the innermost layer is 2 steel wires, and a ring layer is formed by 7 steel wires in the intermediate layer, skin is formed a circle by 12 steel wires and is sub-elliptical tee section state, and the outer outside is provided with an outer winding steel wire; Nexine S twists with the fingers state, and the lay pitch is 12.0mm, and the intermediate layer is that Z twists with the fingers state, and the lay pitch is 18mm, and skin is that S twists with the fingers state, and the lay pitch is 5.0mm.
The utility model is a kind of with outer 20 one high strength steel cords around steel wire, forms by three layers, adds an outer silk that twines at last again.The steel cord of this structure, steel wire and steel wire, strand with thigh between all be that line contacts, fatigue performance is good, simultaneously in the steel cord, in, outer three layers sth. made by twisting is to be ordinary lay, be convenient to ooze strand permeate, improved steel cord corrosion resistance, and, improved the intensity and the twist of cord, so guaranteeing that the tire safety coefficient meets the requirements of under the prerequisite owing to used high-tensile steel wires, can reduce cord weight, reduce the production cost of tire weight and tire plant.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further
Fig. 1 is a kind of structural representation with outer 21 high strength thigh steel cords around steel wire of the utility model.
The specific embodiment
According to shown in Figure 1, outer 20 one high strength steel cords of the utility model band around steel wire, it is made up of 22 steel wires, the innermost layer is 2 steel wires, a ring layer is formed by 7 steel wires in the intermediate layer, skin is formed a circle by 12 steel wires and is sub-elliptical tee section state, and the outer outside is provided with an outer winding steel wire; Nexine S twists with the fingers state, and the lay pitch is 12.0mm, and the intermediate layer is that Z twists with the fingers state, and the lay pitch is 18mm, and skin is that S twists with the fingers state, and the lay pitch is 5.0mm.For line contacts, outermost is an outer winding steel wire between steel wire and the steel wire.
