Abstract
The utility model discloses an improved tyre bead reinforcement structure of a pneumatic tyre. A pair of bead wires are arranged at a bead part, a cord fabric bypasses from the bottom of the bead wires from inside to outside, turns upward and wraps and contains the bead wires and a bead filler, wherein the bead filler is arranged above the bead wires, the part, turning upward, of the cord fabric is a cord fabric rolled edge, a steel strip reinforcement layer is arranged outside the cord fabric rolled edge, tyre bead rubber is arranged outside the steel strip reinforcement layer, a height drop point of the steel strip reinforcement layer is arranged above maximum section width, and distance between the height drop point and the maximum section width is more than or equal to 5mm, so that strength of a tyre bead is improved, and overlapping with other joints and stress concentration are avoided.
Description
Technical field
The utility model relates to a kind of pneumatic tire structure, and especially a kind of tyre bead reinforcement that promotes tyre bead intensity improves structure.
Background technology
Because pitchy road rally match intensity is large, higher to the requirement of strength of tire, having relatively high expectations to tyre bead intensity especially.Generally, rally tire lip mainly comprises tire lip steel wire, triangle rubber, carcass plies, tyre bead glue and tyre bead strengthening course, in the time meeting the rally tire in match, the high-intensity manipulation requests such as sharply turning, anxious acceleration, sudden stop, used the steel band strengthening course to strengthen tyre bead intensity.Use the steel band strengthening course can strengthen tyre bead intensity, still, if the upper height of volume drop point is unreasonable, can cause distribution of stress inhomogeneous, can fall on the contrary the intensity of weak tire.
The utility model content
In order to overcome above-mentioned defect, the utility model provides a kind of air-inflation tyre tyre bead reinforcement to improve structure, and tyre bead intensity that this air-inflation tyre tyre bead reinforcement has improved structural strengthening, can not only meet performance requirement, can avoid again stress to concentrate.
The utility model for the technical scheme that solves its technical matters and adopt is:
A kind of air-inflation tyre tyre bead reinforcement improves structure, the tire lip has a pair of tire lip steel wire, carcass plies walk around and make progress from the bottom of tire lip steel wire from inside to outside turnup and bag put tire lip steel wire and triangle rubber, described triangle rubber is positioned at described tire lip steel wire top, the make progress part of turnup of described carcass plies is cord lock ups, the outside of described cord lock ups is the steel band strengthening course, the outside of described steel band strengthening course is tyre bead glue, and the upper height of described steel band strengthening course volume drop point is more than or equal to 5mm above maximum is disconnected wide and with the disconnected wide distance of maximum.
Be preferably the upper height of described steel band strengthening course volume drop point 5mm above maximum is disconnected wide.
The beneficial effects of the utility model are: the upper height of the steel band strengthening course volume drop point that the reinforcement of the utility model air-inflation tyre tyre bead improves structure is more than or equal to 5mm above maximum is disconnected wide and with the disconnected wide distance of maximum, not only strengthened tyre bead intensity, and avoided and the overlapping of other joints and generation that stress is concentrated.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below, by the particular specific embodiment accompanying drawings specific embodiment of the present utility model, those skilled in the art can understand advantage of the present utility model and effect easily by content disclosed in the present specification.The utility model also can other different mode be implemented, and, under the category do not disclosed departing from the utility model, can give different modifications and change that is.
Embodiment: a kind of air-inflation tyre tyre bead reinforcement improves structure, the tire lip has a pair of tire lip steel wire 1, carcass plies 2 walk around and make progress from the bottom of tire lip steel wire 1 from inside to outside turnup and bag put tire lip steel wire and triangle rubber 3, described triangle rubber is positioned at described tire lip steel wire top, the make progress part of turnup of described carcass plies is cord lock ups, the outside of described cord lock ups is steel band strengthening course 4, the outside of described steel band strengthening course is tyre bead glue 5, the upper height of described steel band strengthening course volume drop point 6 is more than or equal to 5mm above maximum disconnected wide 7 and with the disconnected wide distance H of maximum, most preferably described steel band strengthening course is rolled up upper height drop point 5mm above maximum is disconnected wide.
Above-described embodiment is only illustrative the utility model principle and effect thereof, but not for limiting the utility model.Rights protection scope of the present utility model, should be as listed as claims.
