Abstract
Description
Technical Field
[0001] This utility model relates to the field of all-steel radial tire technology, specifically an all-steel radial tire with heat dissipation function. Background Technology
[0002] All-steel radial tires are defined as tires in which the carcass cords are arranged in a radial direction (at 90° or close to 90° to the center line of the tire crown), and the carcass is tightened by belt layers with cords arranged almost circumferentially.
[0003] Existing all-steel radial tires typically only have cooling grooves on the tread. However, the tire shoulder is the thickest point of the tire section. During vehicle operation, heat accumulates in the tire shoulder, causing the shoulder temperature to rise. The performance of the rubber material in the tire shoulder will decrease due to the heat generated in the tire shoulder, which can easily cause shoulder damage and affect the tire's service life. Furthermore, existing all-steel radial tires are easily punctured when encountering sharp objects such as nails, affecting vehicle operation. Utility Model Content
[0004] The purpose of this invention is to provide an all-steel radial tire with heat dissipation function to solve the problems mentioned in the background art.

The bead ring, steel cord layer, and steel wire cord layer are used to strengthen the structural strength of the tire carcass. A protective mechanism is provided near the steel wire cord layer in the tire carcass for protection, and a heat dissipation mechanism is provided on the outer side of the tire carcass for heat dissipation. The heat dissipation mechanism includes annular grooves for installing copper wire cord rings on the shoulders on both sides of the tire carcass, and copper wire cord rings for heat conduction are connected to the inner wall of the annular grooves.
[0006] Preferably, a copper wire webbing for heat conduction is connected between the two sets of copper wire loops, and the copper wire webbing is connected through the tire body.
[0007] Preferably, the tire carcass has tread patterns for anti-slip purposes on its surface, and heat dissipation grooves for heat dissipation are also provided on its surface.
[0008] Preferably, the protective mechanism includes a chainmail mounted inside the tire body for blocking sharp objects.
[0009] Preferably, the inner wall of the chainmail is connected to a butyl rubber layer for barrier purposes.
[0010] Preferably, the inner wall of the butyl rubber layer is connected to a protective scale layer.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The temperature of the tire body is transferred to the outside through copper wire webbing and copper wire loops, and the wind generated by the vehicle movement is used to cool the tire body; 2. Sharp objects are blocked by chainmail and scale layer to prevent the tire body from being punctured by sharp objects. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1 and Figure 3This utility model proposes an all-steel radial tire with heat dissipation function, including a tire carcass 1 for support, a bead rim 2 installed inside the tire carcass 1, a steel cord layer 3 installed inside the tire carcass 1 near the bead rim 2, and a steel wire cord bundle layer 4 connected to the end of the steel cord layer 3. The bead rim 2, the steel cord layer 3, and the steel wire cord bundle layer 4 are used to strengthen the structural strength of the tire carcass 1. A protective mechanism 5 is provided inside the tire carcass 1 near the steel wire cord bundle layer 4 for protection, and a heat dissipation mechanism 6 is provided on the outside of the tire carcass 1 for heat dissipation.
[0021] The bead rim 2 supports the inner ring of the tire carcass 1, and the steel cord layer 3 and the steel wire bundle layer 4 form a skeleton, increasing the overall structural strength of the tire carcass 1.
[0022] exist Figures 2-5 In the tire carcass 1, the protective mechanism 5 includes a chainmail 501 installed inside the tire carcass 1. The chainmail 501 is used to block sharp objects. A butyl rubber layer 502 for blocking is connected to the inner wall of the chainmail 501. A scale layer 503 for protection is connected to the inner wall of the butyl rubber layer 502. Both the butyl rubber layer 502 and the scale layer 503 are installed inside the tire carcass 1.
[0023] The chainmail 501 blocks larger sharp objects, preventing them from penetrating the tire carcass 1. The butyl rubber layer 502 prevents the chainmail 501 and the scale layer 503 from rubbing against each other, and at the same time absorbs sound, reducing noise between the chainmail 501 and the scale layer 503. The scale layer 503 blocks smaller sharp objects, preventing them from puncturing the tire carcass 1.
[0024] exist Figures 1-3 and Figure 6 In the tire carcass 1, the heat dissipation mechanism 6 includes a tread pattern 601 on the tread surface for anti-skid purposes, and heat dissipation grooves 602 on the tread surface for heat dissipation. An annular groove 603 is provided on the shoulder of the tire carcass 1 for installing copper wire loops 604. A copper wire loop 604 for heat conduction is connected to the inner wall of the annular groove 603. A copper wire webbing 605 for heat conduction is connected between two sets of copper wire loops 604. The copper wire webbing 605 is connected through the tire carcass 1.
[0025] When the tire carcass 1 rolls on the vehicle, the heat dissipation groove 602 allows air to enter and cool the tire tread. At the same time, the annular groove 603 allows air to enter and cool the copper wire webbing 604. The copper wire webbing 605 transfers the heat inside the tire carcass 1 to the copper wire webbing 604. By cooling the annular groove 603, the interior of the tire carcass 1 is cooled.
