Problems solved by technology

[0007] The purpose of the present invention is to provide an inflatable maintenance-free tire, which solves the disadvantages of tires with inner and outer tires that are easy to stab and burst under high load, need to be inflated in time for slow air leakage, and cannot be driven without air pressure; and It solves the problems that the non-pneumatic tires in the prior art cannot compensate for the deformation of the tire crown wear after the tire is worn, resulting in uneven wear or eccentric wear, resulting in reduced service life of the tire and crossed comfort

Embodiment 1

[0033] like figure 1 and 2 As shown, an inflatable maintenance-free tire includes a tire body 1, the top side of the tire body 1 is a crown 3, the inner side of the tire body 1 is a placenta 4, and between the tire crown 3 and the placenta 4 is fetal wall. The tire body 1 is provided with a sealed inner cavity 2, and the tire body 1 is provided with a valve 12 for inflating or deflated the inner cavity 2. In this embodiment, the air valve 12 is arranged on the tire wall.

[0034] In this example, if image 3 As shown, the valve 12 includes a male nozzle 6 and a female nozzle 5. The female nozzle 5 is embedded in the tire wall, preferably vertically arranged. channel 8 , the male nozzle 6 is engaged in the airflow channel 8 , so that the male nozzle 6 and the female nozzle 5 are sealed.

[0035] like Figure 4 and 5 As shown, the specific engaging method is: the side wall of the air flow channel 8 of the female nozzle 5 is provided with a card slot 11, the side wall of t...

Embodiment 2

[0047] This embodiment is further optimized on the basis of Embodiment 1, and the similarities will not be repeated. In this embodiment, several pattern grooves are set on the crown 3, and the valve 12 is arranged on the pattern grooves of the crown 3. inside, such as Figure 7 and 8 shown.

Embodiment 3

[0049] This embodiment is further optimized on the basis of Embodiment 1, and the similarities will not be repeated. In this embodiment, the tire wall is provided with an escape groove 7 in the direction of the inner cavity 2 at the lower part of the carcass, and the valve 12 It is arranged on the side wall of the avoidance groove 7. The escape groove 7 is provided to protect the structure of the air valve 12 .

Abstract

The invention discloses an inflatable maintenance-free tire, and belongs to the technical field of tires. The inflatable maintenance-free tire comprises a tire body, a closed inner cavity is formed inthe tire body, and at least one inflating valve used for inflating or deflating the inner cavity is arranged on the tire body. The tire is novel in structure and high in practicability. 0.5-1.5 kg ofair pressure is inflated into the inner cavity through the inflating valve and is stored in a sealed mode, the comfortableness is improved, meanwhile, deformation of the tire in the driving process is compensated through the air pressure, wrapping and attaching between a crown of the tire and the ground are effectively improved, the ground contact surface is reasonable and balanced, abrasion is uniform, the service life of the tire is guaranteed, and the driving safety of the tire is guaranteed.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to an inflatable maintenance-free tire. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on metal rims, it can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. [0003] With the development of industry, the requirements for tire performance of industrial vehicles and other special...
