What's the pattern of the car tyres? Its principle is briefly described
At present, there are 7 kinds of tread patterns in automobile tires. What are the differences and advantages and disadvantages of different patterns?1, single oriented pattern: pattern ditch is connected with each other, showing an independent pattern block structure.Advantages: the pattern has obvious direction, mole is larger, so it is less cutting lines, born with small resistance, high speed level and control good performance characteristics, suitable for high speed.Disadvantages: loud noise, only for sports tires, because the direction of the installation must be the same as the direction of travel, so it should not be used as a spare wheel.Main applications: sports cars and sports SUV.
The tread patterns are not only for decorative purposes, but also for the performance of tyres, such as traction, braking, turning, drainage, mute, and so on. The most important three functions of tread pattern are: 1. Lifting the grip; 2, reducing noise; 3, increasing drainage. However, these three are in themselves contain each other, and even conflict. Therefore, tire manufacturers in tread pattern design, it is necessary to each tire according to different product positioning, research and design of different pattern design.
Strip pattern: the groove direction of the pattern is consistent with the circumferenceAdvantages: low rolling resistance, not easy to skid, can provide good handling stability and high speed performance, while taking into accountRide comfort and low noise.Disadvantages: poor braking performance and poor stability of the wetland. It is prone to crack during long running under high load.Main uses: good road, truck and bus front wheels.3, symmetrical pattern: tread central groove is accurate, the left and right sides of the same or similar tire patterns, or the other side of the rotation after 180 degrees, patterns can completely coincide.Advantages: mute, comfort is good, because reducing tire rolling resistance, so fuel-efficient is also its advantages, therefore, economic wear resistant tires are using this design.Disadvantages: the symmetrical tread patterns used in cars are smaller, smaller in grip and less athletic in performance.Main use: general economical family car, city SUV and cross-country SUV.
