What are the functions of automobile tires?
Tire is an organic combination of many performances. Its performance indexes include grip (dry, wet), steering, comfort and wear resistance. Many of these indicators are contradictory, such as comfort and handling, grip and abrasion resistance, and so on.In the purchase of the tire, you need to fully consider the vehicle performance (for example: super sports car, SUV, small cars), driving habits (such as mild or intense driving driving style) and hobbies (such as: comfort, noise, high tire) traffic conditions (such as: high speed, gravel Road and road etc.) and climatic conditions (e.g. winter weather) and so on, then according to the positioning of Michelin tire products to choose appropriate your tires.Buy tires must first determine the original vehicle tire specifications. Usually the car tire specifications of the logo is ***/** R** * is digital. (for example: 205/55R16)Different specifications for different patterns are also different.
The modern automobile speed continues to improve, the temperature rise in high speed rolling tire under internal friction intensifies, and will make the physical and mechanical properties of tire materials decreased, at the same time caused by dynamic load increases, working conditions deteriorate, so special requirements of tire safety and reliability in high speed condition, low rolling resistance, long service life, to ensure the safety of and the economy car. The above requirements are often contradictory. Such as large load, tread fast wear, short life; soft and comfortable tires, traction capacity is poor; reduce rolling resistance, fuel saving effect, but the handling stability is poor. According to the Chongqing auto parts industry, the progress of tire technology is focused on resolving these contradictions, so that the structure, material and manufacturing technology of tires have been continuously improved and improved.
(1) and vehicle suspension work together to ease the car at the time of impact and attenuating vibration arising therefrom, to ensure a good car ride comfort and ride comfort; (2) ensure that the wheels and pavement have good adhesion, to improve vehicle traction, braking and passing; (3) the car under gravity force and torque transmission and other direction.
From the Chongqing auto parts industry, the automobile tires are the "shoes" of automobiles. They are the main consumable parts of automobiles, so that 80% of the rubber (natural rubber and synthetic rubber) produced in the world are used to make tires. Tire and wheel is an important component in the vehicle, its function is to support the vehicle; moderated by the impact force from the road; through the attachment of the existing tire road surface to produce the driving force and the braking force to ensure the normal running of the vehicle.
