Abstract

The utility model provides a tire steel wire ring used for bias tyre. The utility model is made by a plurality of cables with no glue on the surface and allotype lateral sections binding side by side. The lateral section of the cable can have straight line edging along at least both sides; the utility model also comprises a plurality of hoops evenly distributed along the circumference of the cable loop for banding cable. The ring traveller made of section wires which is cramped evenly along the circumference by the hoop, and where no flowable glue stock is arranged between the steel wires, can keep the geometric figure during the sulfidation process of the raw tire. The sub mouth of the tyre bands the circular rim with an appropriate force which satisfies the specification and stabilization. As a stressed member with a relatively stable geometric figure, the ring traveller enters the working state in the automobile running process, the banding force of the tyre sub mouth to the circular rim is fairly stable, which can not only convey the automobile horsepower reliably, but also decrease the relative movement of the tyre submouth from the circular rim and the friction heat, which extends the life of the tyre.

Description

Bead wire ring

[technical field]

The utility model is the bead wire ring that is used for diagonal tyre about a kind of, particularly relates to a kind of bead wire ring that is entwined by the special-shaped cross-section steel wire.

[background technology]

In diagonal construction tire is produced, all can in tire, also add a bead coil and strengthen the tightening force of tire wheel rim.Now used bead coil is to be wound in the cyclic structure 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 bead coil 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 bead coil and the bead coil has certain flowing, under the effect of glue that flows and sulfide stress, bead coil can't the original geometric configuration of complete reservation, in addition have at random; Because bead coil 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 bead coil, between each layer steel wire constantly is extruded distortion, and the geometric configuration of bead coil 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, tyre capacity is descended, or cause other accident.

[utility model content]

For solve the defective that above-mentioned bead wire ring exists in actual production and use, the utility model provides a kind of bead wire ring, the steel wire of making this bead coil has special-shaped cross-section, it is out of shape or at random effectively to avoid bead coil to take place in production and use, and keep self geometric configuration, make tyre rim keep meeting the requirements and stable tightening force to wheel rim.

For achieving the above object, the utility model provides a kind of bead wire ring, and it is entwined side by side by many steel wires, and it is straight line that the cross-sectional plane of this steel wire has dual-side at least; It also comprises the cranse of some branch banding steel wires such as circumference along bead coil, and this cranse is along the circumference rectangular distribution of bead coil.

Owing to adopt technique scheme, the utlity model has following beneficial effect: this bead wire ring is because by along circumference well-distributed cranse banding, and there is not flowable sizing material between the adjacent wires, in tire base curing process, himself geometric configuration is kept, as long as bead coil 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 bead coil to be extruded, and counted the thin steel band banding of five equilibrium along circumference, between the steel wire floor of bead coil and the layer, may not misplace between root and the root, bead coil enters mode of operation as the metastable stressed member integral body of geometric configuration 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 tire life; The bead coil that profile wire is made thoroughly solved the diagonal construction tire tyre bead portion to tightening force out of reach designing requirement, the tightening force instability of wheel rim, transmit problem such as power of vehicle change, greatly improved the quality and the reliability of service of diagonal construction tire.

Fig. 2 is the amplification cross sectional drawing of bead wire ring of the present utility model along the A-A face among Fig. 1.

[specific embodiment]

As shown in Figures 1 and 2, the utility model provides a kind of bead wire ring, and 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 bead coil with a plurality of cranses of being made by thin steel band 2 again.As shown in Figure 2, the steel wire that is adopted is a rectangular cross section, can certainly adopt the steel wire of other special-shaped cross-section, having dual-side at least as cross-sectional plane 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 surface of neighbouring steel wire 1 in two-layer, for example: the cross-sectional plane 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 bead coil circumference equally divided position.

The bead coil that this employing profile wire is made since by cranse along circumference banding equably, and there is not flowable sizing material between the adjacent wires, in the tire base curing process, himself geometric configuration is kept, and tyre rim will adhere to specification to the tightening force of wheel rim and be stable; In addition, bead coil enters mode of operation as the metastable stressed member integral body of geometric configuration 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 tire life.
