What are the functions of tire patterns?

The role of the tire tread:

1: Increase the friction between the tire and the ground;

2: Reduce tire noise and enhance comfort;

3: Heat dissipation and drainage for tires;

4: Improve vehicle handling performance;

5: Beautiful, enhance the visual effect.

There are two types of tire patterns: longitudinal patterns and transverse patterns.

Generally speaking, the tire pattern is a groove composed of various longitudinal, transverse and oblique directions on the tire tread. Don't look at these horizontal and vertical patterns are very messy, in fact, they have a clear division of labor. Because of its longitudinal continuity, the longitudinal pattern is mainly responsible for the function of draining water in rainy days, and it is also very helpful for the heat dissipation of tires, but the grip is insufficient.

The transverse pattern has a greater grip ability, which can compensate for the congenital defects of the longitudinal pattern.

The longitudinal pattern of a tire is a pattern arranged according to the circumference of the tire, and this pattern usually has several stripes on a tire (and a small number of tires have only one or none at all).

Contrary to the longitudinal pattern, this pattern is longitudinally disconnected and transversely continuous, so that the tire has large transverse stiffness, better friction and braking effect.

Off-road tires have wide and deep tread grooves, while normal tire tread tires with longitudinal tread and transverse tread tires are suitable for driving on hard roads and are easy to embed into small pebbles. According to the results of some professional tests, the traction of off-road tires is twice that of ordinary tires when driving on dirt roads of the same model. The design of off-road tires in the tread is ingenious, which can improve the driving of the vehicle in mud and other road conditions.

An asymmetrical tread pattern can improve stability. Choose tread-groove-dense tread tires that provide strong grip even in wet wetlands. You can choose a brand that everyone is familiar with.

Such as: Michelin, Goodyear, Zhengxin, Giti. Bridgestone.

All good tires.

The main function of the tire pattern is to increase the friction between the tread and the road surface to prevent the wheel from slipping.

The tire pattern has the performance of improving the ground elasticity of the tread, and under the action of the tangential force between the tread and the road surface (such as driving force, braking force and transverse force), the tread block can produce a large tangential elastic deformation accordingly.

With the increase of tangential force, the tangential deformation of the tire increases, and the "grinding rock annihilation effect" of the contact surface is also enhanced, which in turn hinders the skidding or skidding trend between the tread and the road surface.

This performance largely eliminates the drawbacks of non-tread (smooth tread) tires that are easy to slip, and ensures the normal play of power, braking, steering maneuverability and driving stability related to the friction between tires and road surfaces.

The factors that produce the friction between the tread and the pavement also include the adhesion effect between the two sides, the molecular gravitational effect and the cutting effect of the small-size micro-convex body of the pavement on the Zaochun tread. The main role is still played by the elastic deformation of the pattern block.

The pattern on the tire is the tire traction, braking force, wear resistance, handling stability, drainage, quietness and other ridges, and the use of different pattern designs also greatly affects the comprehensive performance of the tire.

1. The longitudinal pattern of the tire is arranged according to the circumference of the Sakura tire. There are usually several tires in one tire, which is not common in daily use;

2. Compared with the longitudinal pattern, the type is longitudinally disconnected and horizontally continuous. The design makes the tire have a large lateral stiffness, good friction and braking effect, this pattern of tires in the field of professional filial piety is more widely used, such as some agricultural machinery, such as harvesters, tractors, etc.;

3. Block pattern tires are widely used in off-road vehicles. There are three types of them: road tires, all-terrain tires, and mud tires;

4. The single-guide tread grooves are connected to each other, which has strong pavement performance and drainage capacity. Tires have a fixed rolling direction;

5. Asymmetrical tread tires refer to the different pattern structures on the left and right sides. Due to the different structures of the left and right patterns, more attention will be paid to the design of the patterns that increase the landing pressure of the outer patterns when turning;

6. Mixed pattern, so that the longitudinal pattern in the middle that can drain quickly is combined with the horizontal pattern that provides grip on the shoulder to create a perfect situation, so as to form a mixed pattern. At present, this kind of hybrid tire is widely used in most vehicles such as cars, buses, and trucks. (Photo by photo:.)

1. For vehicles driving in the city, the pattern of tires is generally straight and zigzag. This pattern not only enables the car to drive safely on the asphalt road, but also helps eliminate the noise when the car is running, so people call it a silent pattern;

2. For vehicles driving in the wild, the patterns on the tires are deep and wide, which can tightly "gnaw" the road surface, and it is not easy to slip even if it is driving on the snow;

3. Tire pattern is an important part of improving car performance and ensuring driving safety. Therefore, it is very important to correctly choose, install and use tire patterns. According to the purpose of the vehicle and the road conditions and speed of the vehicle, the stress crack chooses the more suitable Mingwang tire pattern.

The pattern on the tire, also known as the tread pattern, plays the same role as the fingerprint of the finger. By molding or engraving the concave and convex parts of the tread of the outer tire, the car can be skiddled when running on the city road, which improves the driving performance of the tire and enhances the appearance.

The types of tread tires are roughly divided into five categories: longitudinal pattern, transverse pattern, longitudinal and horizontal pattern, mud and snow pattern, and off-road pattern. The longitudinal pattern has excellent handling stability, small rotation resistance, and is not easy to slip laterally.

Generally, the clear mold is suitable for road surfaces with good road conditions, such as highways or urban roads. The rolling resistance is small during driving, so the friction with the ground is small, and it has good driving orientation, which is very suitable for high-speed driving.

The horizontal pattern is suitable for bad roads in the wilderness, but it is not as flexible as the vertical pattern. The mainstream tires are a combination of horizontal and vertical, whether it is a hard road, a bad road or a good road can be handled, and there is an asymmetrical pattern mainly used in performance vehicles, good at high-speed cornering.

The longitudinal and horizontal pattern absorbs the advantages of good drainage performance and low noise of the longitudinal pattern, and at the same time takes into account the strength of the dynamic performance of the transverse pattern, and has better driving force and braking force performance than the pure longitudinal pattern. Therefore, this type of tread tire has strong adaptability and a wide range of applications, it is suitable for different hard road surfaces, and roads with poor road conditions can also be dealt with.
