Embodiment Construction

[0017] A radial tire with a bionic crown structure of the present invention will be further described in conjunction with the accompanying drawings.

[0018] The bionic crown structure radial tire crown structure that the present invention proposes is such as figure 1 As shown, it mainly includes a locust-like sole geometric structure tread arc 1, a locust-like sole geometric structure tread arc 2, and a locust-like flexor tendon structure belt layer 3.

[0019] The main control parameters of the imitation locust sole tread arc that the present invention proposes have: L 1 , L 2 , L 3 , L 4 , radius of curvature R 1 , radius of curvature R 2 , driving surface width L, driving surface height H (such as figure 2 shown). The tread width L is consistent with the original tread structure parameters. L 1 , L 2 , L 3 , L 4 , R 1 , R 2 , The specific value of H is determined by optimization according to the specific tire model. where L 1 = L 2 , L 3 = L 4 , and L ...

Abstract

The invention discloses a radial tire with a bionic crown structure. A tire tread arc of the tire imitates the geometric structure on the surface of a locust sole, and the tire tread arc with the thread surface width L consists of two arcs which are symmetrical with each other relative to the center line of the cross section of the tire; the horizontal lengths of the two sections of the tire tread arc are respectively L1 and L2, which are equal to each other and are respectively 50% of the thread surface width L. Two highest points of the tire tread arc are symmetrical with each other relative to the center line of the cross section of the tire, the distances from the highest points of the tire tread arc to the center line of the cross section are respectively L3 and L4, and the lengths of L3 and L4 are respectively 15%-25% of the thread surface width L. A section of high-modulus belted layer is added to the center of a tire tread, and is of a flexor tendon structure which imitates the locust sole, the angle of a steel wire tire cord is 0 degree, and the width of the bionic belted layer is L5 which is 10%-20% of the L. According to the radial tire with the bionic crown structure, the deformation of a crown can be effectively controlled when the tire is grounded, the tire grounding pressure distribution can be improved, and the grounding performance of the radial tire can be improved.

Description

technical field [0001] The invention belongs to the field of auto parts, and relates to a radial tire, in particular to a radial tire with a bionic crown structure. Background technique [0002] The role of the car and the ground is achieved through tires. The performance of tires has an important impact on the ride comfort, handling and safety of the vehicle, and determines the characteristics of the load transfer between the vehicle and the ground. The ground contact mark is the mark formed when the tire is in contact with the ground after the load is applied, and it can reflect the distribution of the ground contact pressure of the tire. The ground pressure distribution has an important influence on the handling stability of the vehicle, and it determines the wear of the tire tread, which has an important influence on the service life of the tire. For wide-base radial tires, due to the wide tread, it is difficult to control the stiffness distribution of the tread, resul...
