Abstract

The DC60 pneumatic tire consists of a tire carcass, which consists of a main carcass part that extends from the tread area through the sidewall to the inner core of the outer bead area. A tread belt layer is arranged inside the tread area and outside the carcass, and an inner tube made of impermeable rubber that forms a cavity in the tire. A barrier layer, which provides enhanced adhesion between the main carcass and the inner tube, is provided between the main carcass and the inner tube. This barrier layer is formed by wrapping a long rubber barrier around the outer surface of the inner tube, which is wrapped around the core, creating a swirling pattern. The pneumatic tire consists of a tire carcass, which consists of a main carcass part that extends from the tread area through the sidewall to the inner core of the outer bead area. A tread belt layer is arranged inside the tread area and outside the carcass, and an inner tube made of impermeable rubber that forms a cavity in the tire. This barrier layer provides enhanced adhesion between the main carcass and the inner tube. A better adhesion between the main parts of the tire body and the inner tube is provided between said main parts of the tire body and said inner tube. Said barrier layer is provided by wrapping a long barrier rubber strip around the outer surface of the inner tube wrapped around the core, forming a swirling pattern of overlapping sections.

Claims (8)

Disclaimers (all) that will not appear on the advertisement page: 1. The bellows tire (1), which consists of a tire chassis (6) with the main body part (6a), which is connected from the tread area (2) through the sidewall (3) to the rim. In the outer tire (5) of the outer tubing area (4), a layer of tread belt (7), which is located inside the tread area (2) and the outside of the carcass (6). ) And inner tubes (8), which are made of tires that are air impermeable and cause cavities in the tires. It is characterized by a barrier rubber layer (12) which ensures a better adhesion between the main body parts (6a) and the inner tube (8) is provided between the main body parts. The said tube (6a) and the inner tube (8), and whereby the barrier (12) layer is formed by a long loop (20) looped rubber band around the surface. The outer part of the inner tube (8) wrapped around the cylinder axis (D) in the periphery, causing Side overlapping part And such a rubber bar (20) is made of a rubber material with the lowest torque (ML) greater than the minimum torque (ML) of sidewall (3G) tires. Tires (3) 2. Rubber bellows (1) as requested in claim 1, where the rubber barrier (12) is arranged in a neat To be placed in region (Y) from position (P1) of the outer end (7e) in the axial direction of the tire of The tread belt layer (7) is attached to position (P2) of the point with the maximum tire width (M). 3. The method of manufacturing the bellows (1), which consists of a tire chassis (6), which contains the main body part (6a), which is a continuation from the tread area (2) through the sidewall area (3). To the inner tube (5) of the outer tube (4) by means of The process of forming the untreated inner tube (S1) by forming the untreated inner tube (8N) on the cylinder core (D), the step (S2) of the barrier rubber layer which also Untreated (12N) on the outer surface of the inner tube. It is not processed (8N) by wrapping an untreated rubber barrier (20) in the direction of the perimeter, creating a lateral overlap. The rubber barrier (20) is made of a rubber material that has The minimum torque (ML) is greater than the minimum torque (ML) of the sidewall tire (3G) in the sidewall area (3) and the untreated carcass mounting process. (S3) by wrapping an untreated (6N) rubber carcass layer on the peripheral surface of the untreated (12N) rubber barrier layer. 4. Method for producing inflated tires (1) as requested in claim 3 by the inner tube molding process which still Untreated (S1), the untreated inner tube (8N) is formed by wrapping a rubber sheet which has not yet been processed. It has been processed one round of width (21) to overlap and connect the two ends (21e) in the periphery. 5. Manufacturing method of bellows (1) as requested in claim 3, whereby the process of forming the inner tube which still The untreated (S1) forms such untreated (8N) inner tubes by stacking and wrapping the tubes. Which has not undergone a long process (22) is a circular pattern in the direction of the perimeter 6. Method of producing inflated tires (1) as requested in claim 3, where such untreated rubber barrier (20) is continuously intertwined from one end of the inner tube, which Untreated (8N) to the other end. 7. Manufacturing method of inflated rubber (1) as requested in claim 3, where in the said (S2) procedure of forming an untreated rubber barrier (12N) rubber barrier Which have not been processed (20), two strips will be used And is wound from both ends of the untreated inner tube (8N) towards its center or From the center out to both ends 8. Methods for producing inflated tires (1) as requested in claim 3, where such untreated rubber barrier layer (12N) has a missing part in the middle (23), which occurs.
