Abstract

The invention discloses a tire structure with shape memory alloy. In the tire structure, a shape memory alloy, such as NITI alloy and the like, is employed as the cord wires inside a belted layer rubber sheets in a certain arrangement manner instead of a steel wire tire cord material in a certain ratio, , so that force distribution on tire tread and tire shoulder is improved by means of a negative thermal expansion behavior and a two-way shape memory effect of the shape memory alloy, thereby reducing steel wire stress at the end of the belted layer in the tire. The tire structure with the shape memory alloy is reduced in strain energy density at the tire shoulder of the tire, is reduced in tire use temperature and is reduced in tire shoulder crack. Meanwhile, the tire structure can enhance the stress on steel wires at the tire tread, so that a tire is improved in rolling resistance performance and service life synergistically. The tire structure can also improve stress concentration at a tire bead.

Description

technical field [0001] The invention relates to a tire belt cord structure, in particular to a tire structure using a shape memory alloy. Background technique [0002] Car tires are the only object that the car contacts with the road, and the performance of the tires is closely related to the fuel economy and driving safety of the car. Radial tires are complex flexible structures composed of various rubber materials and skeleton materials (bead wires, steel cords). The belt layer of a radial tire is the main structure that transmits the force of the tire. It is composed of a cord layer and rubber wrapped around the periphery. The cord layer basically uses steel wire as the material at present, and its mechanical properties are relatively simple. The water seepage of the wire will easily lead to corrosion of the steel cord, which will affect the life of the tire, and the density is relatively high, which will hinder the lightweight design of the tire.
