Abrasion-proofing, puncturing-preventing and safe retreaded tire

Abstract

The invention discloses an abrasion-proofing, puncturing-preventing and safe retreaded tire. The abrasion-proofing, puncturing-preventing and safe retreaded tire comprises a used tire body, and a retreaded tire tread which is adhered to the outer side of the used tire body, wherein lengthways-arranged striped grooves in which buffering layers are arranged are formed in a tread of the used tire body; pattern blocks, and antiskid grooves which are formed by pattern ditches are arranged on and formed in the outer circumferential surface of the retreaded tire tread; an abrasion-proofing layer is arranged on the surface of each pattern block; clamping connecting strips and a puncturing-resisting lining layer are arranged at the inner side of the retreaded tire tread; the clamping strips are in match with the striped grooves by size; soft fitting edges are arranged at the left side and the right side of the retreaded tire tread; a cord fabric layer and the puncturing-resisting lining layer are arranged at the inner side of each soft fitting edge; the cord fabric layers are arranged at the lower sides of the puncturing-resisting lining layers. According to the abrasion-proofing, puncturing-preventing and safe retreaded tire, the abrasion-proofing layers are arranged on the outer side of the retreaded tire tread, so that the abrasion-proofing performance is high; the puncturing-resisting lining layers are arranged at the inner side, the left side and the right side of the retreaded tire tread, so that the puncture preventing performance of the tire can be effectively ensured; and the cord fabric layers at the inner sides of the soft fitting edges are capable of improving the toughness of the soft edges, and thus the use safety of the retreaded tire can be ensured.

Description

technical field [0001] The invention relates to the technical field of tire retreading, in particular to a wear-resistant, puncture-resistant and safe retreaded tire. Background technique [0002] Since the tread of the current tire retreading is mainly block tread segments, when laminating, the tread segments are placed on the polished surface of the glue, and the tread is rolled by the rolling device to discharge the air bubbles. The special rolling device can only bond the tread to the old tire temporarily. During the use of the tire, the tire tread will be squeezed. Slight misalignment will affect the normal use of retreaded tires; in addition, when the tires are in use, tire punctures will inevitably occur, especially where the tread bonding edge is bonded to the old tire, and the soft edge is bonded Thinner, the soft side of the tire is easy to be pulled and even cracked when the tire is used, making it easier for external hard objects to pierce through the gap at the...
