A non-pneumatic tire with bionic vibration-damping webs

Abstract

The invention relates to the technical field of automobile tires, in particular to a non-pneumatic tire with bionic vibration-damping webs, which comprises: a tire crown and a rim joint ring connected by wheel spokes; the wheel spokes are composed of several evenly distributed bionic vibration-damping webs ;The two sides of the bionic vibration damping web along the axial direction are smooth curved surfaces A and B; the contours of the curved surfaces A and B are both asymmetrical arcs, and the asymmetrical arcs reduce the radial direction of the non-pneumatic tire when rolling. The excitation force and the fluctuation of the excitation force are reduced, thereby reducing the radial vibration, and a good shock absorption effect is achieved without any shock absorption device.

Description

technical field [0001] The invention relates to the technical field of automobile tires, in particular to a non-pneumatic tire with bionic vibration-damping webs. Background technique [0002] As the only direct contact medium between the car and the road, the tire directly affects the handling stability, driving safety and riding comfort of the car. However, traditional pneumatic tires have potential safety hazards such as puncture and air leakage, which seriously affect the driving of the car. Safety, so non-pneumatic tires reflect its development advantages with its safety, economy, environmental protection, wear resistance and other advantages. [0003] Existing non-pneumatic tires include a crown, spokes, and rim from the outside in. The spokes of non-pneumatic tires are used to connect the crown and rim, and can replace the air pressure of pneumatic tires to play the role of load-bearing support, traction braking, etc. However, compared with the better mass distributi...

AI Technical Summary

Problems solved by technology

The spokes of non-pneumatic tires are used to connect the tire crown and rim, and can replace the air pressure of pneumatic tires to play the role of bearing support, traction and braking, etc. However, compared with the better mass distribution uniformity of pneumatic tires, non-pneumatic tires are discontinuous The support structure introduces non-uniform mass distribution, which will lead to non-uniform stiffness, which will cause fluctuations in ground pressure and ground area, resulting in overall and local vibration effects, and the vibration effect is more obvious at high speeds and high loads

[0004] Therefore, non-pneumatic tires have prominent vibration problems, which not only limit the speed increase of vehicles equipped with non-pneumatic tires, but also hinder the development of non-pneumatic tires. Therefore, vibration reduction has become one of the keys to the development of non-pneumatic tires.
