Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and typical embodiments.

[0019] exist Figure 1-Figure 3 Among them, the main body of the non-pneumatic hollow tire of the present invention is composed of a crown 1 and a toe 2 interconnected as a whole, and is characterized in that the crown 1 includes a carcass 11 and a wear-resistant layer 12 provided with an anti-skid pattern, which is wear-resistant The layer 12 covers the top pressure bearing surface 111 on the outer surface of the carcass 11, and the toe 2 is provided with an embedded clip 21, wherein: the inside of the carcass 11 is set on the side close to the top pressure bearing surface 111 There is a circular buffer air cavity 112, and a pair of upper oblique arc-shaped cavity walls 1131, inner vertical cavity walls 1132, outer arc-shaped cavity walls 1133 and lower parts are arranged symmetrically on the other side of the carcass 11 near the middle. The l...

Abstract

The invention relates to an inflating-free pneumatic tire. A main body of the inflating-free pneumatic tire consists of a crown and a bead toe which are connected into a whole, wherein the crown comprises a carcass and a wear-resistant layer; an embedded clamping strip is arranged on the bead toe; five buffer air cavities are formed inside the carcass; a left limiting groove and a right limiting groove are externally formed in the joint of the bead toe and the carcass, and a left rectangular buffer air cavity and a right rectangular buffer air cavity are internally formed in the joint of the bead toe and the carcass; the interval between cavity walls of each buffer air cavity is the same; during working, an elastic supporting rib system enabling the tire to have reliable working elasticity is composited, and an anti-puncture pressure bearing working area, an assembly force bearing working area and an assembly limiting elastic working area are formed on the surface of the tire, so that the inflating-free pneumatic tire has reliable working elasticity, an excellent anti-puncture function and a longer reliable working service life; moreover, compared with a conventional automotive inflatable tire, the inflating-free pneumatic tire has general interchangeability, high practicality and excellent economical efficiency.

Description

technical field [0001] The invention relates to a vehicle tire, in particular to an air-free hollow tire with anti-puncture function. Background technique [0002] Traditional pneumatic tires for vehicles are all made up of a cover tire and a closed circular ring-shaped pneumatic inner tube. In the installed state during use, the inner tube is wrapped by the outer tire, inflated and embedded on the rim to form a wheel assembly. When the outer tire is punctured and hurts the inner tube, it is prone to air leakage and flat tire, and when the inner tube is over-inflated, it is also prone to tire blowout, which affects driving safety. It must be sent to a professional point for repair or replacement. In order to resume normal work, there are many inconveniences. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the existing pneumatic tires for vehicles, and provide a non-inflatable hollow tire with relatively simple an...
