Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire technology, and in particular to a heavy-duty radial tire. Background Technology
[0002] Tires are one of the most important components of a car. They play a crucial role, supporting the vehicle's entire weight, bearing its load, and transmitting forces and torques in other directions. Tires prevent severe vibrations and premature damage to other car parts, adapt to the vehicle's high-speed performance, reduce noise during driving, and ensure driving safety, handling stability, comfort, and fuel economy. As the part of the car that directly contacts the ground during driving, tires are prone to damage over time, especially under heavy loads, where high intensity loads accelerate tire wear. Utility Model Content
[0003] The purpose of this invention is to provide a heavy-duty radial tire with a simple and reasonable structure that can greatly improve the tire's strength and durability.
[0004] A heavy-duty radial tire includes a carcass and a tread. The tread is located on the outer side of the carcass and has longitudinal water-guiding grooves and tread blocks on its outer side. The depth of the longitudinal water-guiding grooves ranges from 5mm to 8mm. The carcass includes a nylon belt layer, a steel wire layer, and a radial layer. The nylon belt layer includes two layers: a first nylon belt layer and a second nylon belt layer. The steel wire layer includes two layers: a first steel wire layer and a second steel wire layer. The second nylon belt layer is disposed inside the first nylon belt layer, the first steel wire layer is disposed inside the second nylon belt layer, the second steel wire layer is disposed inside the first steel wire layer, and the radial layer is disposed inside the second steel wire layer. The radial layer has reinforcing cords made of steel wire material, and the steel wires are long filaments with a diameter of 0.3mm to 0.35mm. A triangular rubber is provided at the end of the airtight layer away from the tread, and the triangular rubber contains a bead steel wire bundle.
[0005] The nylon belt layer is made of fiber material, and the steel wire layer is made of metal material. The first nylon belt layer and the second nylon belt layer have the same thickness, and the first steel wire layer and the second steel wire layer have the same thickness.
[0006] The depth of the longitudinal water-guiding channel is 6 mm.
[0007] The tread is a wear-resistant rubber layer. There are three longitudinal water-guiding grooves. The three longitudinal water-guiding grooves divide the upper side of the tread into four equal parts. The two sides are symmetrically distributed with anti-skid tread blocks, and the two middle parts are symmetrically distributed with wear-resistant tread blocks.
[0008] Both the anti-slip patterned blocks and the wear-resistant patterned blocks are rectangular. Anti-slip horizontal lines are provided between adjacent anti-slip patterned blocks and adjacent wear-resistant patterned blocks. The wear-resistant patterned blocks are provided with X-shaped fine patterns. The anti-slip patterned blocks are provided with wavy anti-slip patterns on the upper and lower sides. An anti-slip groove is provided between two wavy anti-slip patterns. The anti-slip groove is elliptical.
[0009] The bead wire bundle contains 4-8 wires.
[0010] The beneficial effects are as follows: This utility model is equipped with two layers of nylon belt, two layers of steel wire, and a radial layer. The tread is a wear-resistant rubber layer, which makes the tire structurally strong, has a high load-bearing capacity, good wear resistance, and increases its service life. The longitudinal water-guiding grooves significantly improve the tire's drainage and anti-skid performance. The anti-skid tread blocks have wavy anti-skid patterns on the upper and lower sides, and an anti-skid groove is provided between the two wavy anti-skid patterns.

The crown is located on the outer side of the carcass and has longitudinal water-guiding grooves 5 and tread blocks on its outer side. The depth of the longitudinal water-guiding grooves 5 ranges from 5mm to 8mm. The carcass includes a nylon belt layer, a steel wire layer, and a radial layer 12. The nylon belt layer includes two layers: a first nylon belt layer 8 and a second nylon belt layer 9. The steel wire layer includes two layers: a first steel wire layer 10 and a second steel wire layer 11.

The three longitudinal water-guiding grooves 5 divide the upper side of the tread into four equal parts. The two sides are symmetrically distributed with anti-skid tread blocks 2, and the two middle sides are symmetrically distributed with wear-resistant tread blocks 3. The middle wear-resistant tread blocks 3 improve the wear resistance of the main contact friction surface, and the anti-skid tread blocks 2 on both sides can improve the anti-skid and wear resistance when turning and changing direction.
