Problems solved by technology

[0002] The anti-slip of ordinary tires mainly depends on the tread blocks. Due to the limitation of tire width, the contact area is limited, especially for two-wheeled tires. When driving, especially when turning or driving on muddy roads, due to the reduced grounding performance, it is easy to slip and cause accidents
[0003] When a two-wheeled vehicle is driving on a muddy road, since the tires are narrow and there are only two wheels, the stability is poor, so it is easy to slip. At this time, the requirements for the grip of the tires are high. There are two main aspects to improve the grip of the tires. One is to increase the tire width, and the other is to increase the groove depth, both of which are to increase the ground contact area of ​​the tire, but the tire width cannot be increased too much due to the limitation of the model, and the groove is too deep when used, it is easy to fall off

Embodiment 1

[0043] Combined with the accompanying drawings, figure 1 is a schematic diagram of the tire turning ground state, Figure 7 It is the force analysis diagram when the tire turns and touches the ground. When the two-wheeled vehicle is turning, the wheels are tilted due to centrifugal force, and the contact point with the ground is no longer the tire crown, but the joint between the tire crown and the sidewall. At the same time, the force on the wheel changes, and the contact point of the wheel tire is affected by four directions of force, namely, the gravity f2 of the driver and the vehicle, the ground support force f1, the ground friction force f4, and the centrifugal force f3. If the friction between the tire and the ground is too small, it will skid and roll over. At this time, the ground friction force f4 is generated by the joint between the crown and the sidewall and the ground.

[0044] There are two main solutions to improve tire grip and increase friction. One is to ...

Embodiment 2

[0050] The grooves on the surface of the tire can increase the friction between the tire and the ground and can better drain water in rainy days. On rainy days or muddy roads, due to the action of rainwater and muddy water, the friction force decreases after the tire surface adheres to rainwater and muddy water. The grooves on the tire surface can collect water and mud well, reduce adhesion and increase friction force.

[0051] to combine figure 1 , figure 2 , image 3 . figure 2 It is a schematic diagram of the surface structure of the tire in this embodiment, image 3 It is a schematic diagram of the cross-sectional structure of the tire of this embodiment. In this example, there is a concave groove 5 between the tire shoulder formed by the anti-skid teeth and the tire crown, and the depth is 5 mm to 12 mm. The other structures are the same as in embodiment 1. The groove 5 surrounds the tire, between the tire shoulder formed by the anti-skid teeth and the tire crown, ...

Embodiment 3

[0053] to combine figure 1 , figure 2 . In this embodiment, there is a groove 6 in the anti-skid shoulder of the tire, and other structures are the same as in Embodiment 1 or Embodiment 2.

[0054] The dimples 6 are evenly distributed in the tire shoulder 2, the size and number of which are determined according to the practicality of the tire, and the depth is generally 5 mm to 12 mm. The concave grooves 6 have a similar effect to the concave grooves 5, and the concave grooves 6 are nearly laterally distributed in the tire shoulder 2, and can further increase the forward frictional force.

Abstract

The invention provide a non-skid tire which comprises a tire tread structure, a tire sidewall structure and tire shoulders, wherein the tire tread structure and the tire sidewall structure comprise rubber, cord fabrics and steel wires; the tire shoulders comprise non-skid teeth and are positioned at two sides of the tire tread; grooves can be arranged between the tire shoulders and the tire tread; and the non-skid teeth can be in a structure of tetragonal pyramids, triangle pyramids, triangular strips, hexagonal pyramids, semi-spheres, and the like. In the invention, the non-skid teeth are designed at the tire tread especially the tire shoulder part, the grooves are additionally arranged, the tire width needs not to be changed to increase the surface area of the tire tread, and the non-skid teeth also increase the frictional force between the tire and the ground, thereby improving the grounding performance of a vehicle and achieving the non-skid purpose.

Description

technical field [0001] The invention belongs to the field of design and manufacture of tires, in particular to the field of design and manufacture of anti-skid tires, in particular to an anti-skid tire suitable for two-wheeled vehicles such as motorcycles and bicycles. Background technique [0002] The anti-slip of ordinary tires mainly depends on the tread blocks. Due to the limitation of tire width, the contact area is limited, especially for two-wheeled tires. When driving, especially when turning or driving on muddy roads, due to the reduced grounding performance, it is easy to slip and cause accidents. [0003] When a two-wheeled vehicle is driving on a muddy road, since the tires are narrow and there are only two wheels, the stability is poor, so it is easy to slip. At this time, the requirements for the grip of the tires are high. There are two main aspects to improve the grip of the tires.
