A spoked non-pneumatic tire with bionic vibration damping function

Abstract

The invention discloses a spoke type non-pneumatic tire with bionic vibration damping function, comprising a tire crown, a spoke plate and a rim combination ring, the tire crown, the spoke plate and the rim combination ring are arranged in sequence from outside to inside along the tire radial direction cloth; the webs are arranged in a matrix at equal intervals along the tire circumferential direction, and symmetrical inner recesses are arranged on both sides of the webs, and the inner recesses are arc-shaped gaps cut along the thickness direction of the webs, and the arc-shaped gaps are It is concave inward toward the center of the web; the starting points of the arc-shaped notch of the concave portion on the adjacent web respectively start staggered from the joint ring of the tire crown and the rim. Beneficial effects: the present invention reduces the radial excitation force through the swinging deformation of the web, reduces the fluctuation of the excitation force, and reduces the radial vibration of the non-pneumatic tire; the vibration damping method can be used for the non-pneumatic tire of the web type, and has a wide range of applications ; The processing is simple and convenient, which saves the cost and realizes the weight reduction of the tire; the structure of the asymmetric arc is simple, which avoids the increase of excessive design and manufacturing difficulty and cost.

Description

technical field [0001] The invention relates to a non-pneumatic tire, in particular to a web-type non-pneumatic tire with a bionic vibration damping function, and belongs to the technical field of vehicle tires. Background technique [0002] Tires are the only parts of a vehicle in contact with the road surface and play a crucial role in the driving process. Although traditional pneumatic tires have the advantages of good adhesion, uniform ground pressure distribution, and good fuel economy, but due to their thin sidewalls and poor resistance to impact, they are easy to cause cuts, punctures, and punctures, which threaten the safety of vehicles. Therefore, non-pneumatic tires have shown a good development advantage with their advantages of safety, economy, environmental protection and wear resistance. The support body of the non-pneumatic tire replaces the inflation pressure to support the mass of the whole vehicle, and bears the tensile and compressive load during the driv...

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
