Radial plate type non-pneumatic tire with bionic vibration reduction function

Abstract

The invention discloses a radial plate type non-pneumatic tire with a bionic vibration reduction function, which comprises a tire crown, a radial plate and a rim combination ring, and the tire crown, the radial plate and the rim combination ring are sequentially arranged from outside to inside along the radial direction of the tire; wherein the radial plates are arranged in a matrix mode at equal intervals in the circumferential direction of the tire, symmetrical inwards-concave parts are arranged on the two sides of each radial plate, the inwards-concave parts are arc-shaped notches cut in the thickness direction of the radial plates, and the arc-shaped notches are inwards concave in the center direction of the radial plates; the starting points of the arc-shaped notches of the inner concave parts on the adjacent radial plates are respectively staggered from the joint ring of the tire crown and the rim. The invention has the beneficial effects that the radial exciting force is reduced through swing deformation of the radial plates, fluctuation of the exciting force is reduced, and radial vibration of the non-pneumatic tire is reduced; the vibration reduction method can be applied to radial plate type non-pneumatic tires, and the application range is wide; besides, the processing is simple and convenient, and the weight reduction of the tire is realized while the cost is saved; in addition, the asymmetric arc structure is simple, and excessive design and manufacturing difficulty and cost are prevented from being increased.

Description

technical field [0001] The invention relates to a non-pneumatic tire, in particular to a web type non-pneumatic tire with a bionic damping function, which belongs to the technical field of vehicle tires. Background technique [0002] Tires are the only parts of your vehicle that come into contact with the road and play a vital role in driving. Although traditional pneumatic tires have the advantages of good adhesion, uniform ground pressure distribution, and good fuel economy, but because of their thin sidewalls and poor impact resistance, they are easy to cause cuts, blowouts, and punctures, which have become threats to vehicle safety. Therefore, non-pneumatic tires have shown good development advantages due to their safety, economy, environmental protection, wear resistance and other advantages. The supporting body of the non-pneumatic tire replaces the inflation pressure to support the mass of the whole vehicle, and bears the tension and compression load during the runni...

Problems solved by technology

However, so far, the existing studies on the vibration reduction of the spokes of non-pneumatic tires are limited to exploring the impact on vibration by changing the structural parameters and materials of the spokes, so as to find a relatively optimized vibration reduction scheme, which is very important for non-pneumatic tires. It is difficult for future real vehicle applications to play a substantial guiding role
