Automotive parts lubrication technology
Whenever we talk about car lubrication, we all think of the common car lubricants, such as engine lubricants, automotive gear oils, transmission lubricants, chassis grease and so on. In fact, these lubricants are only the main parts of the early car in the process of using the required lubricating grease, but need to lubricate the parts are few. With the development of the automobile industry, there are more and more parts and components in the car. Now a car has about 40,000 parts and components. Of these 40,000 parts, the parts that need to be lubricated are also more More and more, so the automotive parts lubrication products are also more and more.
Since the 1970s, one of the most obvious changes in passenger car technology has been the extensive activation of lubrication components, the emergence of many components that require lubrication, and the need for lubrication of the largest number of control components, such as engine power control components, travel agency safety controls Components, automatic transmission control components, body parts in the control of the components, most of these components are concentrated in the body components, engines, air conditioners, bumpers, trim, car seat and other components. The increasingly widespread use of lubricated parts in modern cars has become a trend. Lubricants reduce friction and reduce wear and noise. For example, the use of lubricants on plastic gears or sliders reduces noise; a wide range of plastics that are used in door panels require lubrication, including rails, sliders and rollers, window lifters, micromotors and exterior mirrors Etc. The use of dry film lubricant before the door trim is assembled to the door panel eliminates jarring noise during motor vehicle movement as well as effectively reducing noise on the assembly line using flocked plastic tape and improving assembly line production efficiency.
Since the parts of a vehicle that needs to be lubricated vary in the composition of the vehicle and the working environment in which the vehicle is working is different, the requirements of each product to be lubricated vary greatly. For example: engine parts and transmission parts and other components on the lubrication of products there is a big difference.
Automotive components - General requirements for lubricating products
Friction coefficient is low, because the car's power comes mainly from the engine, so to improve the efficiency of the engine is the main requirement of automotive power. For the lubrication of automotive parts, lubricating products should first have a lower friction coefficient, reduce frictional resistance of parts work, so as to give full play to the efficiency of the engine.
Wide range of temperature to adapt to all kinds of cars driving a wider geographical area affected by the greater climate, especially the engine room components when the engine is also subject to engine heat radiation, so many parts will be The effect of temperature on the lubrication of the product is relatively high temperature requirements.
Long service life, many auto parts in use rarely consider the usual maintenance, are generally used until the end of life to be replaced, so these parts of the life of lubricating products is relatively high, usually The life expectancy of the lubricated products used is higher than the life of these parts.
Pollution to the environment is low, many auto parts, especially the interior parts in its movement, the lubrication parts will be exposed, and some lubrication products will also be with the movement of parts, may cause other interior parts Pollution, and thus the requirements of the lubricating product is not leaked, does not fall off, regardless of oil, do not pollute, at the same time require lubricating product color to light.
Adaptability to parts and components of the material better, automotive components are usually based on different functions and choose different materials, and many automotive parts of the lubricant products also have certain requirements. If these parts use the lubricating products can not meet the requirements of the material, the service life of parts will be doubled or even can not be used.
These are the general requirements of automotive parts for lubrication products. Due to the different functions of auto parts, the composition of the different materials, the use of different parts of the various effects of different roles, and therefore in addition to the general requirements of lubricating products, many auto parts lost lubrication products have specific requirements. Such as: fuel-resistant requirements, anti-radiation requirements, protection requirements, damping requirements, chemical resistance, water resistance requirements, reliability requirements.
The current need for lubrication of auto parts are
1) Body Components: Door Systems, Skylight Systems, Mirrors, Door Lock Systems, Interior Parts, Seat Systems, Wiper and Wash Systems, and Bolts and Fasteners
2) Chassis and Brake System: Suspension Parts, Damping Parts, Brake Cylinder, Brake Master Cylinder, Brake Control System, ABS and TSL Systems
3) electrical and electronic components: all kinds of instruments, connectors, relays, switches, starting system, ignition system, lighting equipment
4) Fuel and air systems: fuel control components, booster components, exhaust gas recirculation control, air control systems
5) Powertrain components: Assembly aids, cooling and air control systems, engine coatings, clutches, cover gasket and transmission and transmission systems.
6) steering mechanism; steering gear, steering connection, power steering assistance.
7) security system; airbags, seat belts, control cables.
