Automotive Rubber Products Applications:
The role of automotive rubber products in automobiles today
(1) Car tires
The tire is one of the important parts of the car. It directly contacts the road surface and works with the car suspension to alleviate the impact of the car when it is running, to ensure that the car has a good ride comfort and smooth ride; to ensure that the wheels and road have good The adhesion of the car improves the traction, braking and passability of the car; under the weight of the car, the important role played by the tire on the car is getting more and more attention.
At present, the main component of most automobile tire materials is natural rubber or synthetic rubber. The comprehensive performance of natural rubber is better than that of synthetic rubber, so natural rubber is often used for high-level tires. In order for rubber to have the properties required for making tires, it is necessary to infiltrate various chemical materials, ie chemical additives, into the rubber. One of the very important additives added is carbon black, because of the adsorption of carbon, the adhesion of carbon particles to rubber molecules is very good, making the rubber enhance the hardness, strength and wear resistance. Because carbon black and rubber are basically equal, the main material of the car tire is actually a composite material of rubber and carbon black.
(2) Sealed products
A modern car has more than 240 sealing accessories. Although these rubber accessories are small, they have a great effect
A. The functions of different types of sealing strips and car sealing strips, in addition to their decorative functions, are mainly able to effectively block the dirt and noise received during driving, play a role in dustproof, rainproof and sound insulation, and also as a car When subjected to vibration and twisting during driving, the sealing strip can also serve as a buffer and shock absorption, giving the car even better cleaning and comfort.
B. Oil seal, mainly used for the sealing of rotating shaft or reciprocating shaft system, can use higher speed, good self-sealing, long service life, is a high-tech precision rubber parts.
C. Brake cup, the brake fluid used in automobile brake system, is the fluid that transmits pressure and realizes braking effect in different automobile hydraulic brake systems.
D. Dust cover. Although the dust cover is simple, it also requires heat resistance, cold resistance, oil resistance, fatigue resistance, ozone aging resistance and good tensile properties.
E. Brake film It is the diaphragm of the brake air chamber, which plays the role of transmitting pressure in the automobile brake system.
F. O-ring. The rubber sealing O-ring used in automobiles has the same function as the sealing O-ring used in other mechanical equipment. Prevent leakage and intrusion of external environmental media and dust. Mainly used for rotating shaft or reciprocating shaft system. O-rings for automobiles are installed on engines, gear boxes, car spindles or in hydraulic and pneumatic drive trains to prevent leakage of lubricating oil, hydraulic oil and other liquids, and ensure the normal operation of each component system.
(3) Shock-absorbing block
Damping blocks are mainly used on automobile engines, chassis and other components to prevent and reduce vibration and noise during automobile driving. Compared with other vibration-damping products, rubber vibration-damping products have the following advantages:
① Freedom of shape;
② It can rotate in X, Y, Z directions, and has the function of spring in six directions:
③It has moderate damping performance and can be used in the range of low frequency to high frequency;
④ At the same time, it has diverse functions such as vibration reduction, buffering and sound insulation;
⑤ Impact stiffness is greater than dynamic stiffness, and dynamic stiffness is greater than static stiffness, which is beneficial to reduce impact deformation and dynamic deformation.
(4) Tape products
Adhesive tape products are mainly used to transmit torque power and speed in automobiles, and transmit power from power source engines to systems and places that require power. Installed in cooling fans, cooling water pumps, brake compressors, booster pumps, air conditioning systems and steering systems. Car tapes are mainly V-belts. Generally, there are three types of V belts, that is, cloth V belt, cutting V belt and multi-wedge V belt. There is no wrapping on both sides of the cutting V-belt. It has good flexibility, large friction coefficient, high stress, high linear speed, good heat dissipation and fatigue resistance, and energy saving. Commonly used rubber types are NBR and CR. Synchronous toothed belts are used for vehicle engine gas ignition. The conditions of use are high speed, high power, and high temperature.
(5) Hose products
Hose products are used in the three major parts of the chassis, engine and body. They are used for the hoses of the seven systems of oil transmission, gas transmission, driving, control, braking, cooling and heating. The types of hoses are fuel hose, water delivery hose, brake hose, vacuum hose, air conditioning hose, radiator hose, power steering hose and special branched hose.
(6) Other products
In addition to the above-mentioned rubber products for automobiles, other major varieties include brake films, leather bowls, and dust covers. The future development focus should adopt fluorosilicone rubber and polyester fabric as the skeleton material for the fuel supply pressure regulator diaphragm for cars; and use chlorinated polyethylene for the diaphragm. As a material for the dust cover, an important requirement is good weather resistance. Neoprene is generally used for constant velocity joints, but with the improvement of heat resistance, the application of polyolefin thermoplastic elastomers has gradually increased. In Europe and the United States, polyolefin thermoplastic elastomers are used in most cars to make dust covers. This type of material can meet the requirements of weather resistance, oil resistance, and heat resistance, and can also reduce the weight of cars.
