Embodiment approach

[0018] by figure 1 , image 3 , Figure 5 , technical requirements, were made into the outer hub and tire crown, and two independent sidewalls. Put the original wheel hub and the outer wheel hub flat on the tire loading machine, respectively install the two sidewalls into the inner and outer hubs, and fill in air to seal the bead until the standard air pressure is reached, such as Figure 6 . Install the outer wheel hub with the worn crown on the grinding machine, after grinding the tread, spread the pre-vulcanized tire crown rubber, and then vulcanize. Combined vacuum tires are suitable for all types of trucks, engineering vehicles and large passenger cars.

Abstract

The invention provides a combined vacuum tire. An outer hub with inward rims is additionally arranged outside an original hub, the whole tire is divided into two independent tire sides and a crown attached to the outer wall of the outer hub, and the independent components can be replaced independently. Twenty downward-concave antiskid grooves are formed in the outer wall face of the outer hub at equal intervals. The rims are arranged on the two stepped edges. An original tire rim and the outer tire rim can be sealed by the inner and outer edge rims of the two independent tire sides in the inflation process to form an airtight air cavity. The outer hub with the worn crown is arranged on a grinding machine, pre-vulcanizing crown glue is laid on the ground tire tread, and vulcanization is conducted. By means of the combined vacuum tire, the manufacturing difficulty can be lowered, the tire tread is prevented from being pierced by sharp objects, the heating of a tire body is reduced, and the retreading rate of the tire is increased.

Description

Technical field: [0001] The invention belongs to the manufacture of automobile tires, and relates to a method for manufacturing combined vacuum tires. Background technique: [0002] The current general-purpose pneumatic vacuum tires for automobiles are a whole. The parts of the carcass are connected to each other and the structure is compact. Air leakage affects driving safety. The worn teeth on the tire crown only account for one-seventh of the entire tire. When the worn teeth are less than the safety standard, or the puncture wound is too large, a new tire must be replaced, and most of the other carcass has not reached the service life of the product. scrap. my country produces hundreds of millions of waste tires every year, and it is still on the rise. In order to improve the safety performance of tires, reduce economic costs, save resources and reduce pollution, countries around the world are constantly developing new tire manufacturing technologies and encouraging and...
