Abstract

The invention relates to an air inflation free tire structure comprising an inner ring connected to a hub, an outer ring connected to tread rubber and an N-type elastomer connected to the inner and outer rings to form an annular air inflation free tire. The N-type elastomer comprises a plurality of elastomeric spokes in the radial direction of the tire, and the widths of the two spokes between theradial spokes respectively occupy half of the width of the radial spokes. The elastomeric spokes are staggered on both sides to be connected to the inner and outer rings. The air inflation free tirecan reduce tire weight and rolling resistance and prevent the occurrence of puncture.

Description

technical field

[0001] The invention belongs to the technical field of auto parts, and relates to a non-pneumatic tire, in particular to a structure of a non-pneumatic tire. Background technique

[0002] At present, due to structural limitations, there is a very important risk of pneumatic rubber tires, which is tire blowout. When a pneumatic tire is running on the road, due to rolling deformation, it is easy to generate a lot of heat in the tread, shoulder and sidewall, and rubber is a poor conductor of heat, and the speed of heat generation is much faster than its dissipation speed. will accumulate inside the tire. If the heat builds up to the point where it changes the chemical properties of the rubber, it can destroy the tire's structural strength and cause a blowout.

[0003] The non-inflatable tire, as the name suggests, does not need to inflate the tire, there is no internal air pressure, and the operation of the vehicle is supported by the structural strength of th...
