Semi-steel radial tire blank

Abstract

The invention provides a semi-steel radial tire blank, which comprises a tire body, a tread and a tire side, wherein the tread is in a rubber strip wrapping structure, namely a single rubber strip is wound on the tire body from the tire side as the starting point along the peripheral direction of the tire body; the adjacent rubber strips are arranged in a clinging manner or a slant stacking manner; the tail end of each single rubber strip is located on the other surface of the tire side, and is finally vulcanized into an overall tire blank body; the width of each rubber strip can be directionally adjusted according to the technological requirements; the width of the new tread is changed by changing the width of each rubber strip; the design structure of a trapezoidal tread made from a traditional single rubber strip and a traditional cutting tread pasting process are changed; the constitutive property and the plasticity of the tire blank are enhanced; the abrasive resistance of the tread of the tire is enhanced; the technological link for manufacturing the tire blank is omitted; the technological zero distance among semi-finished product production procedures is achieved; the production quality of the process is ensured; and the potential quality hazard caused by manual intervention is avoided.

Description

technical field [0001] The invention relates to the production technology of automobile tires, in particular to a semi-steel radial tire blank. Background technique [0002] The tire embryos in automobile tires use molding blocks corresponding to the width of the tire to be laid in multiple layers on the structural layer and then vulcanized. When the molding blocks are docked, a variety of overlapping methods are used to ensure their integrity and connection reliability. Whether it is oblique lap, cross lap, or embedded lap, it is always an application of lap joints. There will be interfaces in the lap joints between the noodle blocks. When the stress generated by the car tires during driving is to a certain extent Tearing or stretching will cause fatal damage to the tire and seriously affect the safety of driving. Contents of the invention [0003] The invention proposes a semi-steel radial tire blank in order to enhance the structure and plasticity of the tire blank, in...
