Abstract
The utility model discloses a cord for a tire with better elongation and permeability, which comprises at least three strands, wherein all strands are twisted together in parallel along the axial centerline in a rotation direction (clockwise or counterclockwise), and the space between the two adjacent strands is equal. Compared with the prior structure, the elongation and permeability of the steel cord are greatly improved, thus improving the driving comfort of cars assembled with radial tires which take the steel cord as the tire reinforcement.
Description
Technical field
The utility model relates to tire, refers more particularly to a kind of steel cord that is used for tire.
Background technology
Along with improving constantly of people's living standard, private car has entered ordinary family.People no longer contented just to automobile to people life bring convenient, and more and more pay attention to the comfort level of driving and riding car.And a framework material that important indicator is exactly a tire of automobile comfort level, usually adopt the steel cord in the present radial-ply tyre as framework material, what described steel cord was selected for use usually is 2+2 * 0.25HT or 1 * 3 * 0.38HT structure, the elongation of these two kinds of structures and permeability are all not so good, have influenced the comfort level of driving and riding car to a great extent.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of elongation and permeability all to be used for the steel cord of tire preferably.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the steel cord that is used for tire, comprise: at least three monofilament, all monofilament are parallel to each other according to a rotation direction along longitudinal center line and are twisted together, and the spacing between the adjacent in twos monofilament equates.
Described steel cord comprises: the monofilament of five diameters between 0.37～0.39 millimeter, the lay pitch of all monofilament is all between 13.3～14.7 millimeters.
The beneficial effects of the utility model are: steel cord described in the utility model, the more original structure of its elongation and permeability is greatly improved, and adopts the driving comfort level of steel cord described in the utility model as the automobile of the radial-ply tyre of tyre framework thereby improved to be equipped with.
