Pneumatic tire with triangular balance outline

Abstract

The invention relates to a pneumatic tire with a triangular balance outline, mainly comprising a tread part, a tire side part, a tire waist part, a tire bead filler, a tire bead part, an inside liner layer, a carcass layer, a tire waist cushion layer, a belt ply and a triangular balance outline supporting piece, wherein the position where the flexing deformation occurs during the movement of the tire is changed, and the contact area between a tread and the ground during the movement of the tire is increased through the arrangement of the tire waist part structure; in such a way, the evenness of grounding pressure of the tire is guaranteed and the biasing wear of the tire is decreased, so that the service life of the tire is prolonged; since the grounding pressure is evenly distributed, the brake performance, the steering performance and the pass performance of the tire are increased, and meanwhile, the safety of automobile driving is guaranteed; under the action of the triangular balance outline supporting piece, the profile outline shapes of the tread part and the tire side part are guaranteed not to change, so that the carcass layer structures and the position shapes in the tread part and the tire side part are enabled not to change; and therefore, the roundness of rolling contact between the tire and the ground is guaranteed, the rolling resistance of tire running is decreased, and the driving safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of tire structure design, in particular to a section profile structure and design method of a pneumatic tire. Background technique [0002] The current tire structure has a narrower running surface due to the smaller cross-sectional contour band and thin shoulder area, so the contact area with the ground is small during the rolling process, resulting in uneven distribution of tire contact pressure, often causing crown, Shoulder wear and partial wear reduce the service life, braking performance and passing performance of the tire; in addition, when the current tire structure is under the action of vertical load and lateral force, the tire is prone to deformation, and the shape of the cross-sectional profile is distorted. It changes the optimal movement and natural balance profile of the tire and increases the rolling resistance of the tire. Although many existing tires increase the profile of the tire by incr...
