Abstract
The utility model relates to a tire bead structure, in particular to a tire bead structure with a steel ring enwrapped by a adhesive piece, and belongs to the technical field of tires. The tire bead structure comprises a tire body, wherein the tire body comprises a tire body main body and a tire body enwrapping part; a steel ring and a triangular rubber strip are enwrapped inside the tire body; a steel ring is positioned at one end of the tire body enwrapping part; the triangular rubber strip is connected at one end of the steel ring; the outer surface of the steel ring is enwrapped by a steel ring enwrapping adhesive piece. The tire bead structure is simple, compact and reasonable in structure; rigid impact between the steel ring and the tire body and a stress concentration phenomenon are solved, so that the bearing capacity of a tire is improved and the service life of the tire is prolonged.
Description
Technical field
The utility model relates to a kind of tire bead structure, and especially a kind of tire bead structure that adopts film parcel steel ring, belongs to tyre technology.
Background technology
Existing wheeled car, particularly large-scale shipping load-carrying vehicle, they run quickly on express highway, and the speed of not only having relatively high expectations also requires good load-carrying capacity, and wherein high bearing capacity is had higher requirement to the tire bead structure of load-carrying vehicle.The key point of tire bead quality mainly contains two parts: being first the bead structure of tire, is secondly tire bead material selection.Tire bead structure particularly, tire bead structure reasonable in design can make the load-carrying capacity of tire obviously strengthen, and Using Life of Tyre increases, and plays the high efficiency hauling operation that Duola hurries up.
In each tire enterprise, tire bead structure is generally comprised of following components at present: carcass 1, tyre bead enhancement Layer 2, steel ring 3, apex strip 4.Described tyre bead enhancement Layer 2, carcass 1 wrap steel ring 3.There is certain defect in above form: one, adopt carcass 1, steel ring 3 material of main parts to be steel wire, under the pressure of high load capacity, rigid shock is comparatively obvious between the two, produces steel wire fracture phenomenon when serious; Two, in prior art, steel ring 3 shapes are generally the polygons such as rectangle, hexagon, are prone to stress concentration phenomenon in its edges and corners, impact even more serious between steel wire.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of tire bead structure, do not changing under the prerequisite of existing equipment structure, solving rigid shock and stress concentration phenomenon between steel ring and carcass, improving load-carrying capacity and the service life of tire.
The technical scheme providing according to the utility model, tire bead structure comprises carcass, carcass comprises carcass main part and carcass turnup, coated steel ring and apex strip in carcass.Steel ring is positioned at carcass turnup one end, and apex strip is connected to steel ring one end, it is characterized in that: the coated steel ring parcel of described steel ring outside face film.
Further, the coated tyre bead enhancement Layer of carcass outside face.
Further, steel ring parcel film adopts elastomeric material to make.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, has solved rigid shock and stress concentration phenomenon phenomenon between steel ring and carcass, load-carrying capacity and the service life of having improved tire.
Accompanying drawing explanation
Fig. 1 is the structural representation of tire bead in prior art.
Fig. 2 is structural representation of the present utility model.
Description of reference numerals: 1-carcass, 1.1-carcass main part, 1.2-carcass turnup, 2-tyre bead enhancement Layer, 3-steel ring, 4-apex strip, 5-steel ring parcel film.
The specific embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 2, the utility model mainly comprises carcass 1, and carcass 1 comprises carcass main part 1.1 and carcass turnup 1.2, the interior coated steel ring 3 of carcass 1 and apex strip 4.Steel ring 3 is positioned at carcass turnup 1.2 one end, and apex strip 4 is connected to steel ring 3 one end.
The coated steel ring parcel of described steel ring 3 outside faces film 5, steel ring parcel film 5 not only plays a protective role to steel ring 3 and carcass 1, plays buffer action, and then improved load-carrying capacity and the service life of tyre bead between steel ring 3 and carcass 1 simultaneously.Described steel ring parcel film 5 adopts elastomeric material to make.
Described carcass 1 outside face is coated tyre bead enhancement Layer 2, by tyre bead enhancement Layer 2, further improves the intensity of carcass 1.
The utility model, by increased elastomeric wear-resisting steel ring parcel film 5 at steel ring 3 and carcass 1, has solved rigid shock and stress concentration phenomenon between steel ring and carcass, improves load-carrying capacity and the service life of tire.
