Description

A sidewall anti-friction structure for radial mode tires of electric vehicles or motorcycles

technical field

The utility model belongs to the technical field of electric vehicle or motorcycle tires, and in particular relates to an anti-friction structure on the sidewall of tires in radial mode for electric vehicles or motorcycles.

Background technique

Tire refers to a circular elastic rubber product that rolls on the ground and is assembled on various vehicles or machinery. It is usually installed on the metal hub, which can support the body, buffer the external impact, realize the contact with the road surface and ensure the driving performance of the vehicle. The tire structure in the prior art is composed of a tire crown, a tire shoulder, a sidewall and a bead. Although the normal running of the vehicle can be realized, when the tire sidewall is impacted by the outside world, the local pressure is too large, causing the carcass to be damaged. damage, or even fracture of the skeleton material, which may cause safety hazards such as tire blowouts. Therefore, it is necessary to further improve the performance of tires in terms of vehicle safety and tire reliability.

Contents of the invention

In order to make up for the defects of the prior art, the utility model provides a tire sidewall anti-friction structure for electric vehicles or motorcycles in radial mode. The utility model can effectively improve various performances of the tire sidewall and solve the problem of excessive local pressure. Problems, improve wear resistance and facilitate tire heat dissipation and gas removal during vulcanization.

The utility model is realized through the following technical scheme: an anti-friction structure for the tire sidewall of electric vehicles or motorcycles in the radial mode, including a crown, a shoulder, a sidewall and a bead, and is characterized in that: the sidewall There are raised ribs and other irregular patterns on it.

The raised ribs are arrow ribs molded on the sidewall.

The raised irregular pattern is a grid pattern, which accounts for 65%-70% of the total area of the sidewall.

The beneficial effects of the present invention are: when the tire side is impacted, the arrow ribs molded on the tire side can disperse the impact force, release the local pressure slowly, and prevent the side of the tire from being scratched, thus protecting the carcass Cord fabric: The raised irregular grid pattern can increase the specific surface area of the sidewall, reduce the bending stress during driving, disperse the heat generation of the carcass, prevent the early aging of the carcass, and prolong the life of the tire; at the same time, it is beneficial to the tire Emission of surface gas during the vulcanization process improves the appearance pass rate.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is a schematic cross-sectional view of the structure of the utility model;

Fig. 2 is the layout diagram of the structure sidewall pattern of the utility model;

Fig. 3 is a schematic diagram of raised arrow ribs at part A of the present invention;

Fig. 4 is a schematic diagram of the raised grid pattern of the B part of the utility model;

In the figure, 1 is a tire crown, 2 is a tire shoulder, 3 is a sidewall, 4 is a bead, 5 is a raised arrow rib, and 6 is a raised grid pattern.

Detailed ways

A sidewall anti-friction structure for electric vehicles or motorcycles with radial mode tires, including a crown 1, a shoulder 2, a sidewall 3 and a bead 4, characterized in that: the sidewall 3 is provided with a raised arrow Ribs 5 and other raised grid patterns 6 .

The raised ribs are arrow ribs molded on the sidewall. When the sidewall is impacted, the raised arrow ribs molded on the sidewall can disperse the impact force, slow down the local pressure, and make the tire The sides are not scratched, thereby protecting the carcass cord;

The raised irregular pattern is a gridded pattern, which accounts for 65%-70% of the total area of the sidewall. The raised irregular gridded pattern can increase the specific surface area of the sidewall and play a role in driving. Reduce the bending stress, disperse the heat generation of the carcass, prevent the premature aging of the carcass, and prolong the life of the tire; at the same time, it is beneficial to the discharge of surface gas during the tire vulcanization process, and improves the appearance qualification rate.

The technologies, shapes and construction parts not described in detail in the present invention are all known technologies.
