CN2846102Y - Radial tyre steel wire ring - Google Patents

Abstract

The utility model relates to a radial tire steel wire ring whose appearance structure is formed by winding the flat bottom or the wedged bottom by multiple steel wires in a multilayer side by side or a dislocation mode, and the cross section of the steel wires is in a hetero shape. The structure also comprises a plurality of ferrules for banding the steel wires, and the ferrules are uniformly distributed along the circumferential direction of steel wire rings. Because of being tightly and uniformly ferruled by the ferrules along the circumference and no flowing sizing material between the adjacent steel wires, the steel wire rings made of heterogeneous steel wires can keep self-geometric shape in the process of tire vulcanization, and the ferrule force of a tire mouth for a tire rim meets design need and is stable. In the process of vehicle running, the steel wire rings as a stress component which is correspondingly stable and is in a geometric shape integrally enter the state of operation, and the ferrule force of the tire mouth for the tire rim is stable. Thus, the utility model not only reliably transfers vehicle power, but also reduces the corresponding movement of the tire mouth and the tire rim, lowers heat quantity caused by attrition, and prolongs the service life of tires.

Description

Radial tyre bead ring

Technical field

The utility model is about a kind of bead wire ring, particularly relates to a kind of radial tyre bead ring that is entwined by the non-circular cross sections steel wire.

Background technology

In radial tyre production, all can in tire, also add a wire loop and strengthen the tightening force of tire wheel rim.Now used wire loop is to be wound in the circulus that multilayer is made with the winding of infantees bar again by the steel wire that glue is applied on many surfaces.At present, the steel wire that is used to make bead wire ring all is the circular cross section steel bead wire, and does not also have special-shaped steel bead wire in the steel bead wire GB.

The wire loop made from the steel bead wire of circle cross-section has following shortcoming: in process of production, when the tire base vulcanizes, glue around the deposited glue of every Steel Wire Surface of wire loop and the wire loop has certain flowing, under the effect of glue that flows and sulfide stress, wire loop can't the original geometry of complete reservation, in addition have at random; Because wire loop is out of shape or at random, the rim of the mouth of the tire of producing will be lower than designing requirement and instability to the tightening force of wheel rim; In use, the rubber between the adjacent wires of wire loop, between each layer steel wire constantly is extruded distortion, and the geometry of wire loop is destroyed continuously, and tyre rim then continues to descend to the tightening force of wheel rim.In running car is particularly run at high speed process, be lower than designing requirement, the tyre rim that continues to descend will influence the normal delivery of power of vehicle to the tightening force of wheel rim, also easily cause tyre rim and wheel rim to relatively move, rub and living heat, make the fatigue damage of tire bead position, reduced the service life of tire; And be lower than designing requirement, the lasting tyre rim that descends to the tightening force of wheel rim and the fatigue damage at tire bead position, the bearing capacity of tire is descended, or cause other accident.

Summary of the invention

Technical problem to be solved in the utility model is: a radial tire ring traveler is provided, the steel wire of making this wire loop has special-shaped cross-section, can avoid wire loop out of shape or at random in production and use, and keep self geometry, make tyre rim keep meeting the requirements and stable tightening force to wheel rim.

For solving the problems of the technologies described above, the utility model is taked following technical scheme: a radial tire ring traveler is provided, and its surface structure twines multilayer side by side by many steel wires or the flat or wedged bottom of multilayer is twined in dislocation, and the cross section of this steel wire is special-shaped; It also comprises the cranse of some banding steel wires, and this cranse circumferentially evenly distributes along wire loop.

Owing to adopt technique scheme, the utlity model has following beneficial effect: this radial tyre bead ring is because by along the equally distributed cranse banding of circumference, and there is not flowable sizing material between the adjacent wires, in tire base sulfidation, himself geometry is kept, as long as wire loop is reasonable in design, tyre rim will adhere to specification to the tightening force of wheel rim and be stable; Owing to the sizing material that does not have between the steel wire of wire loop to be extruded, and counted the thin steel band banding of five equilibrium along circumference, between the steel wire floor of wire loop and the layer, may not misplace between root and the root, wire loop enters duty as the metastable stressed member integral body of geometry in the vehicle traveling process, tyre rim to the tightening force of wheel rim with regard to quite stable, this not only can transmit power of vehicle reliably, and reduced relatively moving of tyre rim and wheel rim, the amount that reduced that friction generates heat is prolonged tyre life; The wire loop that profile wire is made has thoroughly solved oblique tire tyre bead portion the tightening force of wheel rim is not reached designing requirement, tightening force instability, transmits problem such as power of vehicle change, has greatly improved the quality and the dependability of oblique tire.

Fig. 4 is the flat wire loop of radial of the present utility model is tied up the cross section along Fig. 3 an amplification cross-sectional view.

The specific embodiment

As Fig. 1 and Fig. 2, Fig. 3, shown in Figure 4, the utility model provides a radial tire ring traveler, it is after more than 1 on the steel wire of the non-circular cross sections of deposited glue twines multilayer side by side by the surface, to make along the branch bandings such as circumference of wire loop with a plurality of cranses of being made by thin steel band 2 again.

As Fig. 2, shown in Figure 4, the steel wire that is adopted is a rectangular cross section, can certainly adopt the steel wire of other non-circular cross sections, having dual-side at least as shape of cross section is the steel wire of straight line, it needs to guarantee that this steel wire 1 comprises at least one plane respectively with in the contact-making surface of neighbouring steel wire 1 in two-layer, for example: the cross section of steel wire can also be regular hexagon, flat hexagon or cydariform etc., and glue need not applied in the surface of steel wire 1.This cranse 2 is sealing ring bodies of being made through common seaming by thin steel band, and it is installed in along wire loop circumference equally divided position.

The wire loop that the non-circular steel wire of this employing is made since by cranse along circumference banding equably, and there is not flowable sizing material between the adjacent wires 1, in tire base sulfidation, himself geometry is kept, and tyre rim will adhere to specification to the tightening force of wheel rim and be stable; In addition, wire loop enters duty as the metastable stressed member integral body of geometry in the vehicle traveling process, tyre rim to the tightening force of wheel rim with regard to quite stable, this not only can transmit power of vehicle reliably, and reduced relatively moving of tyre rim and wheel rim, the amount that reduced that friction generates heat is prolonged tyre life.
