Problems solved by technology

[0005] The non-pneumatic tires prepared by the existing technology cannot have both load support characteristics and noise, vibration and ride comfort characteristics. For example, when the load support performance of the tire is good, the characteristics of the tire noise, vibration and ride comfort are generally poor; When the noise, vibration, smoothness and roughness of the tire are improved, its load support characteristics are poor

preparation example Construction

[0054] The present invention also includes the preparation method of air-free hollow tire, comprising the following steps:

[0055] ①Put the rubber and auxiliary materials into the internal mixer to mix the mixed rubber, and then roll it into a rubber diaphragm with a thickness of 11-25mm through the calender for many times;

[0056] ②Calculate the quality of the rubber diaphragm required for each layer of the inner ring layer, the middle ring layer, the hollow layer and the outer ring layer, and set aside;

[0057] ③Add the rubber diaphragm of the quality required for the inner ring layer into the mold, pre-vulcanize at 110-163°C for 14-18 minutes, open the left and right flaps of the inner ring layer of the mold, and replace the left and right flaps required by the middle ring layer After adding the rubber diaphragm of the quality required for the middle ring layer, close the left and right flap molds required for the middle ring layer, pre-vulcanize at 110-163°C for 3-4 min...

Embodiment 1

[0068] A kind of air-free hollow tire 1, such as Figure 1~5 As shown, from the inside to the outside are the inner ring layer, the middle ring layer, the hollow layer 100 and the outer ring layer 20, wherein the inner ring layer is the belt layer 110 and the bead layer 120 from the inside to the outside, and the middle ring layer is from the inside to the outside. The outer ones are the shoulder layer 130 and the middle inner ring layer 140 in sequence;

[0069] The outermost edge of the outer ring layer 20 is the tread 10, the tread 10 is in contact with the road surface, the belt layer 110 is installed on the rim of the vehicle, and the hollow layer 100 arranges multiple sets of shock absorbing units along the circumferential array, and each set of shock absorbing units Including the first shock-absorbing hole P1, the second shock-absorbing hole P2, the third shock-absorbing hole P3 and the fourth shock-absorbing hole P4, such as image 3 The shown corners of the first sho...

Embodiment 2

[0076] The preparation method of the non-inflation hollow tire described in embodiment 1, comprises the following steps:

[0077] ①Put the rubber and auxiliary materials into the internal mixer to mix the mixed rubber, and then roll it into a rubber diaphragm with a thickness of 11-25mm through the calender for many times;

[0078] ②Calculate the quality of the rubber diaphragm required for each layer of the inner ring layer, the middle ring layer, the hollow layer and the outer ring layer, and set aside;

[0079]③Add the rubber diaphragm of the quality required for the inner ring layer into the mold, pre-vulcanize at 110-163°C for 14-18 minutes, open the left and right flaps of the inner ring layer of the mold, and replace the left and right flaps required by the middle ring layer After adding the rubber diaphragm of the quality required for the middle ring layer, close the left and right flap molds required for the middle ring layer, pre-vulcanize at 110-163°C for 3-4 minute...

Abstract

The invention discloses an inflation-free hollow tire and a preparation method thereof. The inflation-free hollow tire sequentially comprises an inner ring layer, a middle ring layer, a hollow layer and an outer ring layer from inside to outside; the inner ring layer sequentially comprises a bridle layer and a bead layer from inside to outside, and the middle ring layer sequentially comprises a tire shoulder layer and a middle inner ring layer from inside to outside; the outermost side of the outer ring layer is a tread, the tread is in contact with a road surface, the bridle layer is mounted on a rim of a vehicle, the hollowed-out layer is provided with a plurality of groups of damping units in an annular array, and each group of damping units comprises a first damping hole, a second damping hole, a third damping hole and a fourth damping hole; the corners of the first damping hole, the second damping hole, the third damping hole and the fourth damping hole are in arc transition. The hollowed-out tire structure is a reasonable structure obtained by calculation and optimization through a finite element method, the designed through holes are reasonably distributed in the supporting body in the radial direction and the annular direction, the damping effect is achieved, the weight of the tire can be effectively reduced, and heat convection with the outside is improved, heat generated by rubber due to repeated deformation in the running process of the tire is quickly dissipated, the wear resistance of the tire is improved, and the service life of the tire is prolonged.

Description

technical field [0001] The invention relates to the technical field of tire preparation, in particular to an air-free hollow tire and a manufacturing method thereof. Background technique [0002] The air-free hollow tire supports the load through its own structure without using high-pressure air, so the air-free tire has the advantage of not blowing out the tire. The air-free hollow tire can be installed on small vehicles and heavy equipment vehicles to support the vehicle load and turn the vehicle The power is transmitted to the ground to reduce the vibration and impact from the ground during the driving of the vehicle. [0003] Air-free hollow tires are usually used at a speed of 40-80 kilometers per hour, and are used for low-speed vehicles, special vehicles, or non-motorized vehicles. The existing air-free hollow tires are generally divided into rubber tires and polyurethane tires. It exceeds rubber tires, but its hardness is high and its cushioning performance is weak....
