Bionic non-pneumatic tire

Abstract

The invention discloses a bionic non-pneumatic tire. The bionic non-pneumatic tire comprises a crown, a bionic spoke plate support body and a spoke plate inner ring, wherein the crown, the bionic spoke plate support body and the spoke plate inner ring are sequentially arranged from outside to inside according to the radial direction of the tire; the crown comprises a tread, a cap ply and belt plies, wherein the tread, the cap ply and the belt plies are sequentially arranged from outside to inside according to the radial direction of the tire; the belt plies comprise a # 1 belt ply and a # 2 belt ply which are sequentially arranged from outside to inside according to the radial direction of the tire; and the bionic spoke plate support body is designed by imitating a kangaroo lower limb structure, and the bionic spoke plate support body comprises a kangaroo lower limb-imitated main spoke plate and a supporting auxiliary spoke plate. According to the bionic non-pneumatic tire, shock absorption, drainage and heat dissipation capability of the non-pneumatic tire are remarkably improved, and the overall mass is remarkably reduced; and the bionic spoke plate support body adopts a high-modulus polyurethane material, and thus high hardness, fatigue resistance, cutting resistance and green and environmental protection performance are achieved.

Description

technical field [0001] The invention relates to tire structure design, in particular to a bionic non-pneumatic tire, which belongs to the field of auto parts. Background technique [0002] Traditional pneumatic tires require regular tire pressure maintenance, are easy to puncture and leak, and are easy to cause traffic accidents. Pneumatic tires need to choose suitable materials to meet the various requirements of tires. The materials do not have excellent environmental performance. In terms of military, Traditional pneumatic tires cannot withstand the disadvantages of weapon attacks, and can no longer meet people's needs for various performances of tires. Therefore, major tire companies around the world are researching new tires one after another. Among them, the design, development and application of non-pneumatic tires are the most practical and revolutionary, which not only breaks the design process and design concept of traditional pneumatic tires, but also makes the dr...

[0002] Traditional pneumatic tires require regular tire pressure maintenance, are easy to puncture and leak, and are easy to cause traffic accidents. Pneumatic tires need to choose suitable materials to meet the various requirements of tires. The materials do not have excellent environmental performance. In terms of military, Traditional pneumatic tires cannot withstand the shortcomings of weapon attacks, and can no longer meet people's needs for various performances of tires

Therefore, major tire companies around the world are researching new tires one after another. Among them, the design, development and application of non-pneumatic tires are the most practical and revolutionary, which not only breaks the design process and design concept of traditional pneumatic tires, but also makes the driving fuel economy , handling stability and ride comfort are improved, and the impact of tire vibration on vehicle driving performance is effectively improved. Reasonable criticism, this bionic non-pneumatic tire has improved the above performance, and the material used is environmentally friendly polyurethane material, which can be recycled and used to save resources and protect the environment. It has laid a certain foundation for the development of non-pneumatic tires in the future. foundation, so that the development of tires will stride forward in terms of intelligence, environmental protection and safety
