Description

Technical Field

[0001] The utility model relates to the technical field of all-steel radial tires, in particular to a lightweight bead of an all-steel tire. Background Art

[0002] All-steel radial tires are radial tires with an all-steel cord structure. Compared with radial tires with nylon cords, all-steel radial tires have higher durability, tensile resistance and impact resistance. All-steel cords are usually woven from multiple layers of steel wire. This structural design makes the tire more durable and suitable for high-speed driving and heavy-loaded vehicles. All-steel radial tires are widely used in commercial vehicles, trucks, buses and other heavy vehicles. They can provide better stability, wear resistance and durability, and adapt to various harsh road conditions and high-load conditions. All-steel radial tires are a high-performance tire type suitable for vehicles that need to be used for a long time and at high intensity.

[0003] At present, the all-steel tire market is highly competitive. In order to adapt to the needs of market development, the weight of existing all-steel tires can no longer meet the cost needs of factories, and it is urgent to carry out lightweight design of all-steel tires.

[0009] Preferably, the lower apex is located below the upper apex, above the wire ring, and between the tire bead gasket and the tire body. By designing the lower apex, the connection strength and stability between the upper apex, the wire ring, the tire bead gasket and the tire body can be strengthened.

[0010] Preferably, the carcass is bonded to the upper apex and the lower apex through the wire ring. The carcass is designed to strengthen the structure after the wire ring is wrapped.

[0011] The beneficial effects of the utility model are as follows:

[0012] The utility model adopts a new design without wire cloth covering to effectively reduce the weight of the tire and achieve lightweight tire.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

A carcass 5 is arranged on the wire ring 8, and the carcass 5 is bonded to the upper triangle rubber 7 and the lower triangle rubber 6 through the wire ring 8. The carcass 5 is designed to strengthen the structure after wrapping the wire ring 8.

[0018] See also Figure 1 A lower apex rubber 6 is provided on the carcass 5, and an upper apex rubber 7 is provided on the lower apex rubber 6. The lower apex rubber 6 is between the upper apex rubber 7 and the inner carcass 5. By designing the lower apex rubber 6, the upper apex rubber 7 can be connected to the inner carcass 5 to enhance the tightness of the connection. The upper apex rubber 7 is between the wear-resistant rubber 2 and the inner carcass 5, and is wrapped by the sidewall 1, the wear-resistant rubber 2 and the bead cushion rubber 3 from the inside to the outside. By designing the upper apex rubber 7, the internal structure can be filled to ensure the structural strength.

[0019] See also Figure 1 , Figure 2 The lower apex rubber 6 is located below the upper apex rubber 7, above the wire ring 8, and between the tire bead gasket 3 and the carcass 5. By designing the lower apex rubber 6, it can be used to strengthen the connection strength and stability between the upper apex rubber 7, the wire ring 8, the tire bead gasket 3 and the carcass 5. The carcass cord 4 is bonded to the wear-resistant rubber 2, the inside of the sidewall 1 is clamped with an adhesive plate 9, the inside of the adhesive plate 9 is fixedly connected with a clamping block 10, the clamping block 10 is clamped with the sidewall 1, the inside of the adhesive plate 9 is coated with tire rubber 11, the outside of the tire rubber 11 is bonded with a reflective tape 12, and the reflective tape 12 is bonded to the sidewall 1.

[0020] The specific implementation process of the utility model is as follows: by removing the wire wrap, the disadvantages of high density and heavy weight of the wire material can be reduced. With the cooperation of high hardness wear-resistant rubber 2 and high hardness lower triangle rubber 6, the strength of the steel ring can be kept unchanged. The hardness of the wire ring 8 is greater than that of the lower triangle rubber 6, and the hardness of the lower triangle rubber 6 is greater than that of the upper triangle rubber 7. The tire body 5 has a reverse end point of 30mm-35mm. The upper triangle rubber 7 has a strong adhesive force with the tire body 5, ensuring good anti-destruction performance during driving. The height of the upper triangle rubber 7 is greater than that of the bead pad rubber 3, and the difference is between 15mm-25mm. The angle of the steel wire of the tire body 5 is 90 degrees, symmetrically distributed, and wound over the wire ring 8. The hardness of the wear-resistant rubber 2 is relatively high, between 70-80 Shore hardness. By innovatively designing the tire bead structure and material distribution, the weight of the tire bead is reduced. Compared with the prior art, by applying no wire wrap, the number of bead wire roots is strengthened, the weight of the tire is effectively reduced, and the bead strength is kept unchanged, and the tire performance is not reduced.

[0021] By designing the function of the reflective sticker 12, when the tire of the vehicle is illuminated by the light, the reflective sticker 12 forms a reflection to attract the attention of the driver and pedestrians to avoid accidents.
