Description

Technical Field

[0001] The utility model relates to the technical field of low rolling resistance tires, in particular to a low rolling resistance tire. Background Art

[0002] Tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machinery. They are usually installed on metal rims. They can support the vehicle body, cushion external impacts, achieve contact with the road surface and ensure the vehicle's driving performance. In order to reduce the resistance of the car's driving, a low rolling resistance tire is needed.

[0003] The rolling resistance is closely related to the structure and weight of the tire itself. The bead, as one of the skeleton structures of the tire, is prone to problems such as wire dewlap, loose bead, and relatively poor bonding between the rubber coating and the steel wire during use, which is very unfavorable for its stable use. In addition, the shock absorption effect and comfort of existing tires are poor, which will cause discomfort to the user when driving. Therefore, a low rolling resistance tire is proposed to solve the above problems. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a low rolling resistance tire for solving the problems raised in the above background technology.

[0012] Preferably, the styrene-butadiene rubber layer and the chloroprene rubber layer are in contact with each other, and the styrene-butadiene rubber layer and the chloroprene rubber layer are located between the adhesive layer and the sidewall.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the low rolling resistance tire, by providing a plurality of longitudinal grooves and a plurality of transverse grooves, further reduces the contact area between the tire and the ground, further reduces the rolling resistance, and solves the problem of large rolling resistance of the existing tires when working. By providing an adhesive layer, the adhesive layer can ensure that when the tire rotates, the rubber is embedded in the surface of the steel wire, so that the rubber and the steel wire in the steel belt layer can contact more firmly, and then when the tire is deformed by force and gives a certain pressure to the bead wire, the bead wire can be very firmly protected by the adhesive layer and is not easy to deform and separate.

[0014] By arranging a styrene-butadiene rubber layer and a chloroprene rubber layer, the main material of the styrene-butadiene rubber layer is styrene-butadiene rubber, also known as polystyrene butadiene copolymer, whose physical structural properties, processing properties and product performance are close to those of natural rubber, and it has good elasticity. Some properties such as wear resistance, heat resistance, aging resistance and vulcanization speed are better than those of natural rubber. The main material of the chloroprene rubber layer is chloroprene rubber, which has good physical and mechanical properties, oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance and chemical reagent resistance, and has high tensile strength, which further improves the comfort and solves the problem that the shock absorption effect and comfort of existing tires are poor, which will cause discomfort to users during driving.
