Embodiment 1

[0028] This embodiment is a preferred embodiment of the present invention, see Figure 1-2 As shown, the light-duty truck tire in this embodiment includes a tire body 2 and a tread 1, the tread 1 includes a crown 11, sidewalls 13 and shoulders 12, and the tire crown 11 is arranged on the tire body 2 and rests on the ground. In contact, the shoulder 12 connects the crown 11 and the sidewall 13 .

[0029] The crown 11 is composed of several longitudinal grooves arranged along the circumferential direction of the tire body and a number of transverse grooves arranged along the width direction of the tire body. 9mm, the transverse spacing between the longitudinal grooves is 20mm, the longitudinal grooves are arranged continuously along the circumferential direction of the tire body in a Z-shape, which includes the first longitudinal groove sequence 31, the second longitudinal groove sequence 32, the third longitudinal groove sequence The groove sequence 33 and the fourth longitudi...

Embodiment 2

[0036] Others are the same as those described in Embodiment 1, except that the length of the longitudinal groove is 25mm, the width can be 8mm, the depth can be 10mm, and the spacing between the longitudinal grooves is 25mm; the first transverse groove 41 and The length of the second transverse groove 42 is 5mm, the width is 2mm, and the depth is 4mm; the length of the third transverse groove 43 is 5mm, the width is 2mm, and the depth is 2mm; the length of the fourth transverse groove 44 is 3mm, the width is 2mm and the depth is 2mm. The parameters selected in this embodiment can obtain better main groove volume for the tire and increase the contact area at the same time, so as to better improve the drainage and stability of the tire.

[0037] The length of the long steel sheet 51 on the tire shoulder 12 is 12 mm, and the length of the short steel sheet 52 is 3 mm. The setting of the thin steel sheet on the tire shoulder can improve the rigidity of the tire shoulder, thereby i...

Embodiment 3

[0039]Others are the same as those described in Embodiment 1, except that the length of the longitudinal groove is 28mm, the width can be 10mm, the depth can be 12mm, and the distance between the longitudinal grooves is 30mm; the first transverse groove 41 and the second groove The length of two transverse grooves 42 is 6mm, and width is 2mm, and depth is 1mm; The length of the 3rd transverse groove 43 is 3mm, and width is 2mm, and depth is 2mm; The length of the 4th transverse groove 44 is 1mm, and width is 1mm. 1mm and a depth of 1mm. The parameters selected in this embodiment can obtain better main groove volume for the tire and increase the contact area at the same time, so as to better improve the drainage and stability of the tire.

[0040] The length of the long steel sheet 51 on the tire shoulder 12 is 15mm, and the length of the short steel sheet 52 is 5mm. The setting of the thin steel sheet on the tire shoulder can improve the rigidity of the tire shoulder, thereby ...

Abstract

The invention relates to a light-weight heavy-duty tire which includes a tire body and a tire surface. The tire surface includes a tire crown, a tire sidewall and a tire shoulder. The tire crown is disposed on the tire body and contacts ground. The tire shoulder connects the tire crown to the tire sidewall. The tire crown is composed of a continuous sequence of pattern blocks. The continuous sequence of the pattern blocks is formed in a manner that a plurality of vertical grooves, which are disposed in a peripheral direction of the tire body, and a plurality of transverse grooves, which are disposed in a width direction of the tire body, are arranged in a stagger manner. Each pattern block in the continuous sequence of the pattern blocks is provided with a plurality of thin steel pieces. Multiple petal-shaped grooves are disposed on the tire shoulder at equal intervals. Each thin steel piece is arranged between each two petal-shaped grooves. The light-weight heavy-duty tire is higher in stability, thereby improving driving safety. [0]

Description

technical field [0001] The invention relates to an automobile tire, in particular to a light truck tire. Background technique [0002] The most important thing to consider when a car is running is safety performance, and the safety of tires is a crucial part. The tire is composed of the tire body and the tread. The tread includes the crown, the shoulder and the sidewall. The crown is the part that contacts the road surface and protects the main body of the tire; the shoulder connects the crown and the sidewall; the sidewall is the part that is in contact with the tire body. And fix the tire to the part on the tire main body. The main functions of tires are to transmit driving force, change driving direction, buffer vibration and bear weight, etc., and the safety performance of tires depends to a large extent on its grip and stability. [0003] At present, the tires on the market are mainly the most basic requirements for automobiles. Light vans and trucks carry heavy loads...
