Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of tire bead structure design, and in particular relates to a tire bead reinforcement structure. Background Art
[0002] A tire is a donut-shaped elastic rubber product installed on various vehicles or machinery, usually on a metal rim. It is used to support the vehicle body, cushion external impacts, and achieve contact with the road surface, thereby ensuring the vehicle's driving performance. The tire bead is the part of the tire installed on the rim, also known as the bead. The bead consists of a bead core and a bead cover. Its main function is to firmly fix the tire on the rim.
[0003] However, during use, the airtight layer of a traditional tire bead may generate friction with the rim, causing wear of the airtight layer. Severe wear of the airtight layer will reduce the airtightness of the tire. In addition, the tire bead is generally fixed and shaped by a wire ring. The effect of fixing and shaping by the bead alone is poor, which can easily lead to deformation of the bead and poor safety in use. Utility Model Content
[0004] The purpose of the present invention is to provide a tire bead reinforcement structure to solve the above problems, which can strengthen the bead area, reduce the probability of bead deformation, and improve the air tightness of the bead area, thereby making it more convenient to use.
[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:
[0006] A tire bead reinforcement structure includes a tire carcass, an airtight layer fixedly connected to the tire carcass, two first reinforcement layers fixedly connected to the outside of the airtight layer, two second reinforcement layers fixedly connected to the inside of the tire carcass, two shaping glues provided inside the tire carcass, and a reinforcement ring fixedly connected to the inside of the shaping glue.
[0007] As a preferred solution of this embodiment, the reinforcement ring is made of metal, and the cross-section of the reinforcement ring is a circular structure.
[0008] As a preferred solution of this embodiment, the second reinforcement layer is made of elastic steel mesh, and the first reinforcement layer is made of rubber.
[0009] As a preferred solution of this embodiment, a cord layer is wound around the outside of the tire carcass, a first steel wire layer is wound around the outside of the cord layer, and a second steel wire layer is wound around the outside of the first steel wire layer.
[0010] As a preferred solution of this embodiment, two spacers are wound around the outer side of the second steel wire layer, and a nylon belt layer is wound around the outer side of the two spacers.
[0011] As a preferred solution of this embodiment, a crown is provided on the outer side of the nylon belt layer, and the crown is fixedly connected to the tire carcass.
[0012] As a preferred solution of this embodiment, shoulders are provided on both sides of the tread crown, and two grooves are provided on the tread crown.
[0013] As a preferred solution of this embodiment, a plurality of tread blocks are fixedly connected to the tread crown, and the plurality of tread blocks are distributed in a circumferential array about the center of the tire carcass.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] The utility model can play a certain protective role on the airtight layer through the contact between the first reinforcement layer and the rim, thereby preventing the airtight layer from being damaged by friction and causing tire leakage, which can effectively improve the airtightness of the bead area. The second reinforcement layer can play a certain supporting role on the bead area, which can cooperate with the reinforcement ring to better support and shape the bead, reducing the probability of bead deformation.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] See also Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a tire bead reinforcement structure, comprising a tire carcass 1, to which an airtight layer 2 is fixedly connected, two first reinforcing layers 3 being fixedly connected to the outer side of the airtight layer 2, two second reinforcing layers 4 being fixedly connected to the interior of the tire carcass 1, two shaping adhesives 5 being provided inside the tire carcass 1, and a reinforcing ring 6 being fixedly connected to the interior of the shaping adhesives 5. In this embodiment, the contact between the first reinforcing layer 3 and the rim provides a certain degree of protection for the airtight layer 2, preventing the airtight layer 2 from being damaged by friction and causing tire leakage, thereby effectively improving the airtightness of the bead area. The second reinforcing layer 4 provides a certain degree of support for the bead area, thereby cooperating with the reinforcing ring 6 to better support and shape the bead, reducing the probability of bead deformation, thereby making it more convenient to use. The shaping adhesive 5 can fix the reinforcing ring 6.
[0023] See also Figure 1 and Figure 2 As shown, the reinforcing ring 6 is made of metal and has a circular cross-section, which can reinforce the tire bead. The second reinforcing layer 4 is made of elastic steel mesh, and the first reinforcing layer 3 is made of rubber, which can further strengthen the tire bead.

The first and second steel wire layers 8, 9, reinforce the tire carcass 1. Two spacers 10 are wound around the outside of the second steel wire layer 9, and a nylon belt layer 11 is wound around the outside of the two spacers 10. The nylon belt layer 11 and the spacers 10 secure the first and second steel wire layers 8, 9. The cord layer 7 supports tire pressure and strengthens and solidifies the tire, while the first and second steel wire layers 8, 9, reinforce the tire carcass 1.
